The Estate of Burton Kanter and Naomi Kanter appeal a decision of the Tax Court. This consolidated appeal deals with six out of forty-one separate issues decided by the Tax Court with respect to alleged deficiencies of the late Burton W. Kanter, his wife, Naomi Kanter, and related entities, as well as two additional post-trial issues. We affirm in part and reverse in part.
INTRODUCTION
The late Burton W. Kanter,1 and various family entities associated with him, have been audited by the Internal Revenue Service virtually, if not literally, every year since Richard Nixon was President. Kan-ter was a well-known and accomplished tax and estate lawyer. He graduated from the University of Chicago Law School. He had a very successful law practice beginning in 1956, founding what would eventually become the law firm of Neal, Gerber & Eisenberg. Among Kanter’s clients was the Pritzker family of Hyatt Corporation fame. Kanter was also an accomplished businessman, with “extensive exposure” to a “good many public .... [and] private companies.” (Tr. at 5278.)2 Kanter wrote extensively on tax-related subjects (originating a “Shop Talk” column in the Journal of Taxation), and was an expert on the subject of trusts and estate planning. See, e.g., Burton W. Kanter & Michael J. Legamaro, The Grantor Trust: Handmaiden to the IRS and Servant to the Taxpayer, 75 Taxes 706 (1997); Sheldon I. Banoff & Burton W. Kanter, LLC Announcements: Damage Control, 80 J. Tax’n 255 (1994); Burton W. Kanter & Sheldon I. Banoff, Tax Planning for the Elderly, 70 J. Tax’n 191 (1989); Burton W. Kanter, AARP—Asset Accumulation, Retention and Protection: Prelude to Transmission, 69 Taxes 717 (1991); Burton W. Kanter, Cash in a “B” Reorganization: Effect of Cash Purchases on “Creeping” Reorganization, 19 Tax L. Rev. 441 (1964). In the 1960s and 1970s, Kanter helped Hollywood finance movies through tax shelter arrangements, and was involved in the production of many major Hollywood films, including “One Flew Over the Cuckoo’s Nest.” The IRS’s extraordinary attention to Kanter is understandable given that from 1979 to 1989 Kanter, the highly successful tax attorney, who hobnobbed with Pritzkers and Hollywood producers and who participated in countless extremely large and lucrative business ventures, reported a negative adjusted gross income each year on his federal tax return and paid no federal income taxes. (Tr. at 5290-91.)
This consolidated appeal involves Kan-ter’s petitions for review of deficiencies assessed during the years from 1978 to 1986, which is itself only a portion of the original consolidated case tried by the Tax Court in 1994 — -a trial that generated almost 5500 pages of transcript, more than 4600 pages of briefs and thousands of exhibits consuming hundreds of thousands of pages, and was eventually, five years later, distilled into a 606 page opinion covering forty-one separate issues. A thorough description of the entire factual background to this case can be found in the Tax *839Court’s opinion. Investment Research Associates, Ltd. v. Comm’r, 78 T.C.M. (CCH) 951 (1999) [hereinafter IRA]. The trial was conducted by Special Trial Judge Cou-villion, to whom the Tax Court had assigned the case under 26 U.S.C. § 7443A(b)(4). See also Tax Court Rule 180.3 Under the Tax Court’s rules, the Special Trial Judge (STJ) then submitted a report containing findings of fact and opinion to the Tax Court’s Chief Judge, who then assigned the case to Tax Court Judge Dawson. See Tax Court Rule 183(b). Judge Dawson subsequently issued his opinion, which stated that the Tax Court “agrees with and adopts the opinion of the Special Trial Judge, which is set forth below.” IRA, 78 T.C.M. (CCH) at 963. Of the forty-one issues decided by the Tax Court, six were appealed to this court:4
1. Fraud: The Tax Court determined that Kanter (and two colleagues) helped individuals obtain business opportunities in exchange for payments that later were fraudulently diverted through a series of Kanter-controlled entities in order to disguise the payments’ origins and lower the tax assessed on the income (by dividing it up and assigning parts of it to various entities claiming losses). Kanter concedes that there was an underpayment of taxes but disputes that the Commissioner was able to prove by clear and convincing evidence that the underpayment was due to fraud.
2. Bea Ritch Trusts: Kanter challenges the Tax Court’s determination that capital gains reported in 1986 by the Bea Ritch Trusts (BRT) were properly taxable to Kanter under the grantor trust provisions of the Internal Revenue Code (IRC).
3. Washington Painting: Kanter challenges the Tax Court’s refusal to allow him to deduct expenses he incurred during an aborted sale of a painting.
4. 1982 Bank Deposits: Kanter challenges the Tax Court’s determination of a deficiency for the year 1982 based upon an analysis of his bank deposits. He argues that the Commissioner failed to meet his burden to prove a deficiency, that the Tax Court erred in presuming the Commissioner’s deficiency determination to be correct, and that in any event the evidence Kanter presented at trial was sufficient to overcome any presumption of correctness.
5. Equitable Leasing: Kanter challenges the Tax Court’s determination that payments from Equitable Leasing Company to Kanter entities were taxable commissions and not loans.
6. Cashmere: The Tax Court disregarded a series of transactions involving (a) the contribution of certain partnership interests to a shelf corporation (Cashmere) and (b) the subsequent installment sale of Cashmere’s stock, the result of which was an immediate recognition of capital gain to Kanter on the partnership interests. Kan-ter argues that the transactions had economic substance and should not have been disregarded as an attempt to avoid the payment of federal income tax.
*840The remaining two issues in this appeal concern events after the conclusion of the Tax Court’s trial. Beginning in April 2000, Ranter sought repeatedly to have the original report filed by the STJ placed in the record, or in the alternative made available for this Court’s review in camera. Ranter alleged that informal conversations with two Tax Court judges had revealed that the issued opinion had undergone significant alterations from the original report filed by STJ Couvillion. The Tax Court denied all of Ranter’s motions. Ranter appeals the Tax Court’s refusal to produce the STJ’s original report. The final issue concerns Ranter’s wife’s (Naomi’s) efforts to seek innocent-spouse relief from the deficiencies levied against her husband’s estate.
To make this very complex case easier to understand we have placed a brief statement of facts relevant to each issue immediately preceding that issue’s analysis. We begin with the broadest (and least fact dependent) issue: whether the STJ’s original report should have been made part of the record on appeal. Then we address the six transactional issues from the Tax Court’s decision. Finally, we address Naomi Ranter’s post-trial motions.
The United States Courts of Appeals have exclusive jurisdiction to review decisions of the United States Tax Court. 26 U.S.C. § 7482(a)(1); Seggerman Farms, Inc. v. Comm’r, 308 F.3d 803, 805 (7th Cir.2002).
I. The STJ’s Report
Ranter’s first argument is that the STJ’s original report must be made a part of the record on appeal so that this court can determine whether the appropriate degree of deference had been paid to it by the Tax Court judge, whose opinion is before us. Ranter claims that informal conversations between his attorney and other Tax Court judges revealed that the STJ who presided over the trial of this case submitted a report that found Ranter credible and recommended rejection of much of the Commissioner’s assessed deficiencies, specifically the fraud deficiency. Ranter argues that the STJ’s report cannot be rejected by the Tax Court unless clearly erroneous, and that, without the STJ’s report in the record, there is no way for this court to determine if proper deference was accorded it. Moreover, this secret and unaccountable process of review allegedly violates Ranter’s due process rights. Ranter, relying on a Supreme Court.case examining the relationship between U.S. district court judges and magistrate judges, argues that this quasi-collaborative process affords a Tax Court the opportunity to reverse an STJ’s credibility findings without first hearing or seeing the witnesses itself — thus offending due process. See United States v. Raddatz, 447 U.S. 667, 681 n. 7, 100 S.Ct. 2406, 65 L.Ed.2d 424 (1980) (observing in dicta that in the criminal context a district court judge’s reversal of a magistrate judge’s credibility findings without the district judge hearing or seeing the witnesses would raise “serious questions”). Ranter argues that in addition, our review of the Tax Court’s decision is unconstitutionally impaired by the omission of the STJ’s report from the record. Ranter’s challenge of the Tax Court’s refusal to include the “original” STJ report presents questions of law that we review de novo. Pittman v. Comm’r, 100 F.3d 1308, 1312 (7th Cir.1996).
Of course, Ranter’s arguments are immaterial if the Tax Court’s final opinion is the STJ’s report. See Ballard, 321 F.3d at 1042-43. The Tax Court’s final opinion clearly states that it “agrees with and adopts the opinion of the Special Trial Judge.” IRA, 78 T.C.M. (CCH) at 963. The Chief Judge of the Tax Court, Judge *841Dawson, and Special Trial Judge Couvil-lion himself all signed that final opinion, and we take their statement at face value. Therefore, notwithstanding Ranter’s attorney’s declaration, we accept as true the Tax Court’s statement that the underlying report adopted by the Tax Court was in fact Special Trial Judge Couvillion’s. See Ballard, 321 F.3d at 1042-43. This renders moot all of Ranter’s arguments.
But even if, as the dissent suggests, the phrase “agrees with and adopts” masks what is in fact a quasi-collaborative judicial deliberation in which an STJ’s initial findings are malleable, neither the Tax Court’s own rules of procedure, the Federal Rules of Appellate Procedure, nor Congress’ scheme for appeals from Tax Court decisions would require the Commissioner to include the STJ’s preliminary report as part of the appellate record. Furthermore, this purportedly quasi-collaborative process would not offend our notions of fundamental fairness, nor would due process require the inclusion of the report in the appellate record to preserve the fairness of our review.
First, it is clear that the Tax Court’s own rules do not require the report to be disclosed to the parties or made part of the appellate record. To the contrary, its rules specifically preclude the report’s disclosure. That the Tax Court has the power to prescribe its own rules of procedure is undisputed. See 26 U.S.C. § 7453; Stone v. Comm’r, 865 F.2d 342, 347 (D.C.Cir.1989) (“The Tax Court is of course free to make its own rules determining the relation between it and its Special Trial Judges.”). Having exercised that rulemaking authority, the Tax Court no longer requires an STJ’s report to be made available to the parties and, by extension, no longer allows those parties to file objections to it. Compare Tax Court Rule 182(b), (c), 60 T.C. 1149, (1973) (providing for service of the STJ’s report on each party and allowing each party to file objections to the report’s findings), with Tax Court Rule 183, 81 T.C. 1070, (adopted 1983) (noting that “[t]he prior provisions for service of the [STJ’s] report on each party and for the filing of exceptions to that report have been deleted”).
Neither do the Tax Court procedures prescribe any particular level of deference due the STJ’s report. Under the current rule, the Tax Court maintains sole authority to decide cases assigned to an STJ. Tax Court Rule 183(c) (“The Judge to whom or the Division .to which the case is assigned may adopt the [STJ’s report] or may modify it or may reject it in whole or in part .... ”); see also Freytag v. Comm’r, 501 U.S. 868, 875 n. 3, 111 S.Ct. 2631, 115 L.Ed.2d 764 (1991) (“[A] special trial judge has no authority to decide a case assigned under [§ 7443(b)(4)].”). The Tax Court thus acts as the original finder of fact. Conversely, the STJ’s inability to decide cases limits the amount of deference that the Tax Court, as the original factfinder, must pay to those preliminary findings. Although the Rule requires that “due regard” be given to the STJ’s opportunity to evaluate the credibility of witnesses and that those findings be presumed correct, see Tax Court Rule 183(c), to impose the further requirement that the Tax Court review an STJ’s findings for clear error, as Ranter urges, would all but abdicate the Tax Court’s original decisionmaking authority. Instead, we believe Rule 183’s due-regard language merely instructs the Tax Court to be cognizant that the STJ had the opportunity to evaluate the credibility of witnesses, and allows the Tax Court to overcome the presumption of correctness it prescribes should it find that the evidence suggests those findings were incorrect. Consequently, secreting the report does not offend any rule-mandated *842check on the Tax Court’s power to decide cases assigned to an STJ.
Second, Congress has by statute precluded direct appellate review of STJ reports. We lack jurisdiction to review anything but “decisions of the Tax Court.” 26 U.S.C. § 7482(a)(1). We have repeatedly held that the use of the term “decisions” in § 7482 means that the appellate courts can review only (i) dismissals (e.g., for lack of jurisdiction) or (ii) formal determinations of deficiency (or lack thereof). See, e.g., Kreider v. Comm’r, 762 F.2d 580, 584 (7th Cir.1985). In other words, a “decision” of the Tax Court is the final formal ruling of the Tax Court; a preliminary “report” is not a decision. See 26 U.S.C. § 7459(a) (“A report upon any proceeding instituted before the Tax Court and a decision thereon shall be made as quickly as practicable. The decision shall be made by a judge in accordance with the report of the Tax Court, and such decision so made shall, when entered, be the decision of the Tax Court.” (emphasis added)). An STJ report, therefore, is not reviewable, see Estate of Smith v. Comm’r, 638 F.2d 665, 670 (3d Cir.1981), which lends credence to the Commissioner’s argument that Congress intended STJ reports to be treated as preliminary findings comprising part of the Tax Court’s internal deliberative process.
Third, the Federal Rules of Appellate Procedure do not require that STJ reports be made part of the statutorily required record on appeal of a “decision” of the Tax Court. Federal Rule of Appellate Procedure 14 excepts appeals of Tax Court decisions from certain rules of appellate procedure.5 Among those rules not applicable to Tax Court review is Rule 16, which provides that the record on review of an administrative order shall include “any findings or report on which [the order] is based.” FED. R. APP. P. 16(a)(2). Unlike other administrative actions, the Federal Rules of Appellate Procedure thus do not require that Tax Court decisions be reviewed in light of the preliminary findings upon which the decision was based. Instead, Rule 13 notes that Rule 10 governs the contents of a Tax Court appellate record, and that rule does not require the record to include any preliminary findings or reports. Fed. R. App. P. 13 & 10(a)6
With these considerations in mind, we find that the relationship between the preliminary reports of STJs and the final, reviewable “decisions” of the Tax Court bears striking resemblance to the relationship between reports of “divisions” of the Tax Court and final decisions of the Tax *843Court itself. A “division” is a subset of the Tax Court (often a single judge) that is designated to hear a single case and is empowered to make determinations with respect to disputes before the Tax Court. 26 U.S.C. §§ 7444(c), 7460(a). Under § 7460, the division’s decision generally becomes the decision of the Tax Court, but the Tax Court retains the power to review the division’s decision and render its own. Those preliminary recommendations of the division which do not become part of the final decision of the Tax Court also do not become part of the record for any additional future review. Id. § 7460(b) (“The report of a division shall not be a part of the record in any ease in which the chief judge directs that such report shall be reviewed by the Tax Court.”).
Thus, the two circuits to have interpreted § 7460 have ruled that a division’s preliminary report is not part of the appellate record and not available for review by a federal appeals court once the Tax Court has undertaken an internal review. See Estate of Varian v. Comm’r, 396 F.2d 753, 755 n. 2 (9th Cir.1968); Heim v. Comm’r, 251 F.2d 44, 48 (8th Cir.1958). The Ninth Circuit noted a congressional intent in § 7460 to preclude a two-tier appellate relationship between the division and the full court and determined that such a mandate did not offend the court’s notions of fundamental fairness. Varian, 396 F.2d at 755 n. 2.
Given the similarities between these two relationships, we are led to the same conclusion that the Ninth Circuit reached in Varían: there is no two-tier appellate relationship between STJs and the Tax Court. Instead, STJ reports are treated by the Tax Court as preliminary findings only and, in accordance with applicable rules and statutes, are not required to be made part of the record on appeal.
The dissent takes issue with this comparison, noting that divisions are comprised of one or more Tax Court judges, who are all presidentially appointed and serve a fifteen-year, statutorily mandated term of office from which they can be removed only for “inefficiency, neglect of duty, or malfeasance in office but for no other cause.” 26 U.S.C. § 7443(f). STJs, however, serve at the discretion of the Chief Judge and have no statutorily mandated term of office. Id. § 7443A. If Tax Court Rule 183 provides for a quasi-collaborative process, the dissent fears this distinction between the participants impairs the judicial independence of the STJ. As a result, the dissent questions whether an STJ can participate meaningfully in this internal deliberative process. See post at 87.
We respectfully disagree. We are hesitant to suggest that members of the Tax Court would either expressly coerce or by nature of their office exert undue influence over an STJ. Nor will we discredit an STJ’s express statement that the final Tax Court opinion “agrees with” his own based solely on this observed distinction.
This procedure, while admittedly unusual vis a vis typical judicial procedure, does not offend our notions of fundamental fairness. See Varian, 396 F.2d at 755. In this respect, we agree with the dissent’s conclusion that due process neither requires the Tax Court to be constrained by a formal degree of deference to the STJ nor requires the Tax Court to rehear witnesses whether or not it ultimately reverses the STJ’s findings. See post at 89-94 (discussing United States v. Raddatz, 447 U.S. 667, 100 S.Ct. 2406, 65 L.Ed.2d 424 (1980) and Universal Camera Corp. v. NLRB, 340 U.S. 474, 492-94, 71 S.Ct. 456, 95 L.Ed. 456 (1951)). Although dictum in the Supreme Court’s decision in Raddatz suggests that “serious questions” may *844arise from a district court’s reversal of a magistrate judge’s credibility findings without the opportunity to personally see or hear the witnesses, see 447 U.S. at 681 n. 7, 100 S.Ct. 2406, that observation was made within the context of a criminal appeal. In a civil tax proceeding, a party’s interests are more akin to those at stake in a typical administrative adjudication, and we agree with the dissent that the risk of erroneous deprivation in a civil proceeding is neither “as high, nor the costs as great, as would be the case in a criminal milieu.” See post at 93 (discussing Tax Court Rule 183 within the procedural-due-process framework established by Mathews v. Eldridge, 424 U.S. 319, 333, 96 S.Ct. 893, 47 L.Ed.2d 18 (1976)). Moreover, we agree that the “only fully responsive remedy” to Ranter’s complaint would prove unworkable, as it would require the enormous burden and prohibitive cost of rehearing witnesses, which would ultimately prove to add little value given the continued input that the STJ retains under Tax Court Rule 183’s purportedly quasi-collaborative process. See post at 883-884.
But the recognition that little value would be added to the process given the STJ’s continued involvement — signified by his adoption of the statement that the final Tax Court opinion reflects his own opinion — is ultimately why we take issue with the dissent’s conclusion that our review of the Tax Court’s opinion is unconstitutionally impaired by this procedure. The conclusion rests on the premise that STJs do not enjoy an equal voice in this purportedly quasi-collaborative process. See post at 886-887. As discussed above, we reject this premise. In as much as the final Tax Court opinion purports to agree with and adopt the opinion of the STJ, we therefore believe that the final opinion reflects the true legal opinions and findings of the STJ. Any differing preliminary recommendations — if they ever existed — would no longer be constitutionally relevant because the STJ has abandoned them. Should he feel otherwise, we would expect him — or the Tax Court — to say so.
As the Eleventh Circuit recently noted, “there is nothing unusual about judges conferring with one another about cases assigned to them.” Ballard, 321 F.3d at 1043. If Tax Court Rule 183 in fact provides the opportunity for STJs and Tax Court judges to conference regarding the STJ’s preliminary findings, then we have every reason to believe that Tax Court judges would duly regard the input of the STJ and that he, in turn, would participate meaningfully in the exchange. Like the Ninth and the Eleventh Circuits, we too are loath to interfere with another court’s deliberative process. See id.
In any event, the issue is academic since the Tax Court’s opinion in this case purports to “agree with and adopt” Special Trial Judge Couvillion’s opinion. We will take the Tax Court at its word and, thus, move on to a discussion on the merits of Ranter’s appeal.
II. Fraud
A. Facts
The bulk of the Tax Court’s opinion involves its determination that certain income tax underpayments were made with fraudulent intent. The facts surrounding the fraud issue are the most complex of all and will be described as succinctly as possible.
The Tax Court’s decision tells a story of Ranter and two business associates—Robert Lisle and Claude Ballard. Lisle and Ballard worked in real estate, principally as managers in the real estate division of Prudential Insurance Company, where they had significant authority and influence over the conduct of Prudential’s busi*845ness. Kanter, Lisle, and Ballard concocted a plan whereby they would use Lisle and Ballard’s positions along with Ranter’s legal skills to collect and hide payments from people who wanted to do real estate business with Prudential.7
The Tax Court focused on five individuals (referred to collectively as the Five) who paid Kanter, Lisle, and Ballard for their influence.8 For the Five, Lisle and Ballard would help secure business opportunities with Prudential, and in return the Five made payments, including cash and partnership interests, to Kanter.
It was at this point that the IRS became interested. According to the Commissioner these payments were diverted (the Commissioner and Tax Court use the more highly charged word “laundered”) to entities created by Kanter or someone acting at Ranter’s direction. The dominant method was to divert payments to a Kan-ter-controlled corporation called Investment Research Associates, Ltd (IRA).9
The payments to IRA were deposited in the accounts IRA kept with another Kan-ter-eontrolled entity called the Administration Company. The Administration Co. was exactly what its name indicates: a company that administered the records and funds of its clients. It maintained books and records for its clients, and often prepared client tax returns. Additionally, it administered client funds, collecting receivables and paying bills. Money for clients was kept in pooled bank accounts listed under Administration Co.’s name. Two of these accounts were called the Special E account and the TACI Special Account. Client funds were pooled in order to get the higher rate of return on aggregated funds and to avoid a multiplicity of account maintenance charges on many, smaller client bank accounts kept in the clients’ individual names. Administration Co. itself (and not the bank where the accounts were kept) tracked individual client balances within the pooled accounts on its internal records for each client. IRA and many of its subsidiaries were clients of Administration Co.10 In fact, it does not appear that Administration Co. had any significant clients not directly associated with (or controlled by) Kanter.
The payments by the Five to IRA that were deposited in the accounts of the Administration Co. were commingled with other non-Five-related funds of IRA as *846well as the funds of other Administration Co. clients. This commingling and the inadequate record keeping of Administration Co. made it difficult to track or account for the payments from the Five.
It was IRA — and not Kanter, Lisle, or Ballard — that reported the income from the Five’s payments on its tax return (where it was off-set by aggregated losses). Subsequently, IRA distributed the income into subsidiary “sham” corporations, BWK, Carleo, and TMT, controlled by Kanter, Lisle, and Ballard, respectively, in a 10/45/45 ratio, respectively, that represented the division of the payments allegedly agreed to by Kanter, Lisle, and Ballard.11 These sham corporations were used, in effect, as the personal bank accounts of Kanter, Lisle, and Ballard, and these men could withdraw or use the funds contained in them at their leisure.12 The funds withdrawn were never repaid and were eventually written off as bad debts. Alternatively, the controlled corporations’ funds were used to fund the personal expenditures of Kanter, Lisle, and Ballard, as well as their families.
Kanter, on the other hand, argues that the payments to the corporations were merely investments by the entities, “ceded” to them by Kanter. The underlying scheme of securing business opportunities for the Five interested individuals in return for payments to Kanter (through Kanter entities) is disputed in its entirety by Kanter.
The Commissioner argued, and the Tax Court agreed, that this income was properly taxable to the individuals, and a deficiency was assessed. The Tax Court held that the diversion of these funds from the individuals to the sham corporations was undertaken with the fraudulent intent to evade the payment of taxes. According to the Tax Court, this arrangement not only disguised income earned by the individuals, but also hid their activities from Prudential.
In the Tax Court, Kanter presented an impressive list of witnesses associated with Kanter, Lisle, Ballard, the Five, and the various relevant entities — all of whom expressly denied that the Five paid “kickbacks” to Kanter for steering business the Five’s way. But the Tax Court found that these witnesses had testified that the Five had, in fact, entered into payment arrangements with Kanter, Lisle, and Ballard in exchange for their influence in obtaining business. IRA, 78 T.C.M. (CCH) at 1065. This testimony established that Kanter had not reported income on which he was taxable and had therefore underpaid his federal-income-tax obligations. The Tax Court found that these underpayments were undertaken with intent to evade taxes based on, inter alia, the following factors: the lack of credibility of Kanter’s testimony; Kanter’s legal education and experience indicating an awareness of his obligation' to report income accurately and pay taxes; Kanter’s substantial underreporting of income for many years; Kanter’s creation of a eom-*847plex laundering network of sham corporations and other entities that made it difficult to trace the flow of funds; Ranter’s lack of cooperation with the IRS — namely, the withholding of documents and the destruction of documents subject to summonses; Ranter’s commingling of “kickback” monies with other monies in the Administration Co.’s accounts; Ranter’s movement of monies through conduits that had no legitimate business purpose showing an intent to disguise sources of funds; Ranter’s reporting of his personal income on the tax returns of IRA in order to create the appearance that income was earned by IRA; and Ranter’s use of phony loans to disguise distributions to himself, later written off as bad debts. IRA, 78 T.C.M. (CCH) at 1083-85.
B. Analysis
A finding of fraud by the Tax Court is a factual finding that we review for clear error. Toushin v. Comm’r, 223 F.3d 642, 647 (7th Cir.2000). As with all findings of fact of the Tax Court, we must view the evidence in the light most favorable to the Tax Court’s findings and reverse only if we are left with the definite and firm conviction that a mistake has been made. Pittman, 100 F.3d at 1312-13.
To establish fraud, the Commissioner must prove by clear and convincing evidence that Ranter’s underpayment of taxes was done with intent to evade taxes that he knew or believed were owed. Toushin, 223 F.3d at 647; Pittman, 100 F.3d at 1319. Fraud may be proven through circumstantial evidence. Pittman, 100 F.3d at 1319. There are a variety of commonly recognized indicia of fraud, “such as keeping a double set of books, making false entries or alterations, [using] false invoices or documents, [destroying] books or records, [concealing] assets or covering up sources of income, handling ... one’s affairs to avoid making the records usual in transactions of the kind, and [undertaking] any conduct, the likely effect of which would be to mislead or to conceal.” Spies v. United States, 317 U.S. 492, 499, 63 S.Ct. 364, 87 L.Ed. 418 (1943). Additionally, fraud can be shown by significant and repeated understatement of income, Pittman, 100 F.3d at 1320, by a lack of cooperation with investigating agents, Korecky v. Comm’r, 781 F.2d 1566, 1568-69 (11th Cir.1986); Zell v. Comm’r, 763 F.2d 1139, 1146 (10th Cir.1985), by destruction of records, Powell v. Granquist, 252 F.2d 56, 59 (9th Cir.1958), or by considering the legal experience and education of the taxpayer, Plunkett v. Comm’r, 465 F.2d 299, 303 (7th Cir.1972).
Ranter’s principal argument is based on the representation he makes above concerning the STJ’s report: Ranter and his witnesses were found credible, and his story was believed by the STJ. Therefore, there can be no finding of intent to defraud. It was, Ranter alleges, only the rejection of the STJ’s findings by the Tax Court judge that led to the finding that Ranter was not credible and that the underpayment of taxes was accomplished with fraudulent intent. As discussed above, we refuse to credit Ranter’s allegations in light of the Tax Court’s statement that it “agrees with and adopts” the opinion of the STJ. Therefore, Ranter’s principal argument is without merit. The Tax Court found that Ranter’s testimony was not credible and also found significant circumstantial indicia of fraud. Ranter’s arguments now do not demonstrate that this is clearly erroneous.
Ranter’s remaining arguments are also meritless. He argues that it is a common estate planning technique to cede personal investments to family trusts and corporations. But he does nothing to undermine *848the considerable evidence cited by the Tax Court that demonstrates that the Five paid for Ranter, Lisle, and Ballard’s help in securing business opportunities, and that those payments went through IRA to Carleo, TMT, and BWK for division of the proceeds in a 10/45/45 split. And inasmuch as this argument seeks to show a lack of fraudulent intent by attacking the existence of a deficiency, this argument was expressly waived by Ranter.
Additionally, Ranter argues that fraud was raised by the respondent late in the process by the Commissioner’s amendment to his Answer, that none of the Commissioner’s notices of deficiency indicated fraud and that IRS agents’ reports had found no intent to defraud. While the Tax Court might have found this persuasive when, as the trier of fact, it considered the issue of fraud, this argument is unpersuasive at this stage. Ranter does not argue that the Commissioner’s amendment was improperly allowed or otherwise defective. Nor is the Commissioner’s delayed amendment particularly probative of the sufficiency of the fraud evidence, given the difficulties facing the Commissioner in unraveling the relevant transactions during the time leading up to (and during) the trial.
Finally, Ranter’s attacks on the circumstantial indicia of fraud are little more than efforts to recharacterize the evidence in a manner favorable to Ranter’s version of events. But a review of the record in the light most favorable to the Tax Court’s findings makes clear that it was not clear error to find significant indicia of fraud.
To review just a few of the relevant indicia: first and foremost, even Ranter concedes that he significantly underreport-ed his income from the transactions with the Five over many years. (Pet. Br. at 33.)
Second, the money earned by Ranter through the transactions with the Five was diverted to IRA and commingled with other monies, where the funds were reported as income earned by IRA, before ultimately becoming available to Ranter personally — a complicated money trail that made it difficult to trace the flow of the funds and gave the appearance that the money had been earned by IRA.
Third, there was evidence that Ranter and those acting at his behest did not cooperate with investigating agents and even destroyed records that the IRS had requested formally through its summons power. See 26 U.S.C. § 7602. James Lunk, an IRS Case Manager, was asked during his testimony at trial what records Ranter and his representatives had provided voluntarily, to which he responded, “Generally they were records that really wouldn’t do us a lot of good in the examination in terms of really getting at the type of information we needed to examine the transactions that we were most interested in.” (Tr. at 1055-56.) IRS Agent Paul Dion testified similarly:
I have some very direct recollection[s] of the meeting, because it was the first time I met Mr. Ranter. And at the very beginning of the meeting, we discussed some — had a very nice conversation relating to very general type[s] of topics. I remember art was one of them, and a few other generalities. And as soon as we started discussing the required documentation, it was almost as if a different person appeared. And that person became, I guess, very demonstrative in terms of not wanting to provide us with the information that we asked for; basically saying that he was going to frame the issue and not us.
(Tr. at 831-32.) The Commissioner had to seek the assistance of the district court in order to enforce summonses against Ran*849ter seeking documents relevant to the present case. The district court, in two separate rulings, indicated that Kanter had not cooperated and that documents had been destroyed even after the IRS summonses for those documents had been issued.13 The court stated that
[Solomon] Weisgal testified that since [receiving a summons to compel production of documents], some of the BK documents, including summoned documents relating to the Kanters, had been turned over to the Administration Company and that some have been discarded as part of a three-year record retention and discard policy.... [Linda] Gallenberger testified that she disposed of some documents [related to Kanter] after receipt of the IRS summons.
United States v. Administration Co., 74 A.F.T.R.2d 94-5252, 1994 WL 240518, at *2 (N.D.Ill. May 31, 1994). The district court went on to note that
The facts are that the Kanters first promised to produce the documents sought from [entities involved in the present case] and then, in early February 1994, notified government counsel that the Entities were third-parties over whom they had no control. The eleventh-hour change of position by the Kanters is indicative of bad faith on the part of the Kanters.
Id. at *3. Less than a month later, the same judge held Gallenberger in contempt for a continuing failure to comply fully with IRS summonses. United States v. Administration Co., 74 A.F.T.R.2d 94-5256, 1994 WL 285064, at *2 (N.D.Ill. June 23, 1994) (“Gallenberger misconceives her duty to use all reasonable efforts to comply with the summonses. A half-hearted request and cursory further search are insufficient”) (internal quotations and citations omitted).
These and the other indicia cited by the Tax Court, when considered in a light favorable to the Tax Court’s findings, paint a clear and convincing picture of an intent by Kanter to evade the payment of taxes he knew or believed that he owed. It was not clearly erroneous for the Tax Court to find that Kanter’s underpayment of taxes involved fraud.
III. Bea Ritch Trusts
A. Facts
The Bea Ritch Trusts (BRT) are a group of twenty-five trusts established in 1969 under one trust document. The trust document named Beatrice Ritch, Kanter’s mother, as the grantor of BRT, Kanter’s friend and business associate Solomon Weisgal as the trustee and the members of Kanter’s family as the beneficiaries. According to the trust document, Beatrice Ritch funded each of the separate BRT trusts with a $100 check. No evidence (beyond the trust document itself) was presented to substantiate that this actually happened. Kanter himself was originally named as a beneficiary of twenty-four of the twenty-five trusts and he alone was granted a power of appointment over the beneficial interest of BRT. Kanter allegedly renounced his interest in BRT in 1971, 1977, and 1978, thereby purportedly eliminating his power of appointment over BRT. At sometime during or before 1987, *850however, sixty new beneficiaries were added to BRT.
Before 1987, Kanter borrowed money from BRT, and as of January 1, 1987, Kanter still owed the trust $287,080. This debt does not appear to have been secured, nor is there any indication in the record that a reasonable interest rate (if any) was charged on the loans.
In the early 1970s Kanter participated in business ventures in Long Island, New York, involving the then nascent cable television industry. He and other members of his law firm helped an entity that eventually became Cablevision Co. raise funds, secure financing and find investors for its cable business. In return, Kanter (along with others) was to receive interests in partnerships that themselves owned interests in Cablevision.14 Kanter arranged to have BRT receive the Cablevision partnership interests to which he was entitled — in essence he contributed the Ca-blevision partnership interests to BRT. The Tax Court found that the contribution of Kanter’s Cablevision partnership interests (along with other income and assets) to BRT was the principal source of funding for BRT. Kanter, therefore, was the true grantor of BRT. IRA, 78 T.C.M. (CCH) at 1098-99.
In 1987, BRT reported capital gains of $2,033,368 for the fiscal year ending September 30, 1987, from the sale of the Ca-blevision partnership interests owned by BRT.15 Because Kanter was the true grantor of BRT and because he had a power of appointment to name beneficiaries of BRT, the Commissioner assessed a deficiency for the year 1987 against Kanter with respect to BRT’s income from the Cablevision sale. At trial, the evidence made clear that the income at issue had been earned during the calender year 1986, and the Commissioner sought to amend his pleadings and reallocate the BRT deficiency from 1987 to 1986. The Tax Court allowed the amendment, and denied Kanter’s request to shift the burden of proof to the Commissioner for having raised a “new matter.” See Tax Court Rule 142(a)(1).
The Tax Court found that Kanter had failed to prove that he did not fund BRT and, despite his three renunciations of any beneficial interest in BRT, that he had not appointed the 60 new beneficiaries. As a result, the Tax Court held Kanter hable for tax on BRT’s income for 1986 and 1987 under the IRC’s grantor trust provisions. 26 U.S.C. §§ 671, 674. The Tax Court also found that, in the alternative, Kanter’s borrowing of trust funds made him taxable on BRT’s income. See 26 U.S.C. § 675(3).
B. Analysis
1. Was the allowance of the amendment proper?
Kanter’s first argument concerns the Tax Court’s allowance of an amendment of the pleadings to conform to the proof that the alleged deficiency relating to BRT applied to 1986 rather than to 1987. Kanter argues that it was error to allow this amendment at all, and that, once allowed, *851the Tax Court further erred by not treating this as a “new matter” under Tax Court Rule 142(a), which would have shifted the burden of proof on the issue to the Commissioner.
The decision to allow or deny an amendment of the pleadings under Tax Court Rule 41 is reviewed for abuse of discretion. See Estate of Ashman v. Comm’r, 281 F.3d 541, 542 n. 2 (9th Cir.2000); LeFever v. Comm’r, 100 F.3d 778, 786 (10th Cir.1996); Braude v. Comm’r, 808 F.2d 1037, 1039 (4th Cir.1986). It was not an abuse of discretion for the Tax Court to allow the amendment of the Commissioner’s pleadings to reallocate the BRT deficiency to 1986. Kanter was on notice as to the specific partnership income of BRT that was the subject of the assessed deficiency. (Tr. at 4483-86.) There was no prejudice to Kanter in the adjustment of the date, and he had a fair opportunity to defend with respect to the amended claim. In fact, it was Kanter, and not the government, who elicited the testimony (from Kanter’s accountant, Gallenberger) that revealed the timing error and prompted the government’s request for amendment.16 The government apparently did not realize its error until Kanter pointed it out at trial. Further, Kanter points to no additional evidence that he was prevented from introducing by virtue of the late amendment. The amendment of the pleadings to conform to the evidence was proper.
2. Should the amendment have shifted the burden of proof?
Kanter argues next that the amendment to the pleadings was a new matter that shifted the burden of proof on this issue to the Commissioner. See Tax Court Rule 142(a)(1) (“The burden of proof shall be upon the petitioner, except ... that, in respect of any new matter, ... it shall be upon the respondent.”). The distribution of burdens is a question of law that we review de novo. This argument fails as well. The Commissioner is allowed the latitude to amend his pleadings and even adopt entirely new theories supporting assessed deficiencies without triggering Rule 142’s shift in burden, so long as the new theory is not inconsistent with the original allegation, does not require new evidence in its support, nor increases the amount of the deficiency. See, e.g., Friedman v. Comm’r, 216 F.3d 537, 543 (6th Cir.2000) (“A new position taken by Commissioner is not necessarily a ‘new matter’ if it merely clarifies or develops Commissioner’s original determination without requiring the presentation of different evidence, being inconsistent with Commissioner’s original determination, or increasing the amount of the deficiency.”); Abatti v. Comm’r, 644 F.2d 1385, 1390 (9th Cir.1981) (same); Achiro v. Comm’r, 77 T.C. 881, 890, 1981 WL 11333 (1981) (same).
The problem for Kanter is that the Commissioner’s amendment did not offer a new theory for the alleged deficiency. The theory under which the Commissioner pro*852ceeded at all times was that specific transactions produced taxable income that was reported by BRT but which was properly taxable to Ranter by virtue of the grantor trust provisions of the tax code.17 The case relied upon by Ranter here supports our conclusion. Achiro involved an amendment under which the Commissioner alleged for the first time that a deduction was improper under a section of the tax code completely different from the section originally argued. 77 T.C. at 889-90; see also Shea v. Comm’r, 112 T.C. 183, 190-92, 1999 WL 177471 (1999). The Commissioner’s amendment here presented a much more modest change, more akin to a clarification of the original allegation. Nor is Ranter correct when he alleges that the amendment increased the assessed deficiency. The stated deficiency remained constant, and involved the same income from the same transactions, but was reallocated from one disputed year to another disputed year to correct a calender error that did not prejudice Ranter’s case.18 The Commissioner did not propose additional income nor require Ranter to defend against a larger deficiency than had been assessed before the amendment. Therefore, it is incorrect to claim that the amendment resulted in “an entirely new and increased deficiency in a different year.” (Pet. Br. at 46 (emphasis in original).) The Tax Court was correct in determining that the amendment did not shift the burden of proof to the Commissioner.
3. Ranter was the grantor of BRT
Although Ranter argues principally that the Commissioner should have borne the burden of proving that Ranter was the grantor and owner of BRT, and that the Commissioner could not meet that burden, Ranter maintains that, regardless of burden, he is not taxable on BRT’s income under the IRC’s grantor trust provisions. A finding of grantor status is a factual finding that we review for clear error. Scott v. Comm’r, 226 F.3d 871, 874 (7th Cir.2000). Ranter has failed to show that the Tax Court’s decision was clearly erroneous.
Despite the trust document’s showing that Beatrice Ritch was the grant- or of BRT, the familiar principle of substance over form views as the true grantor the one who principally funded the trusts. Schulz v. Comm’r, 686 F.2d 490, 496 (7th Cir.1982); United States v. Buttorff, 761 F.2d 1056, 1060-61 (5th Cir.1985). In Schulz, for example, the petitioner’s wife was considered the grantor of a family trust because both the Commissioner and this court disregarded the conveyance of the wife’s assets, which were subsequently used to fund the trust in question, to the petitioner. 686 F.2d at 496. The wife, in substance, provided the funds for the *853trust, and the form of the funding, by routing the funds through the petitioner, was ignored. Similarly, although Ranter was not listed in the trust document as a grantor, and, even if Beatrice Ritch actually did contribute $100 towards the funding of each BRT trust, there is evidence that Ranter contributed to BRT income and assets he earned, to substantially fund the twenty-five trusts.
The Tax Court found that Ranter transferred to BRT income and assets associated with his services in the Cablevision transactions as well as others. IRA, 78 T.C.M. (CCH) at 1098. Ranter provided no evidence (other than the trust document itself) to show that Beatrice Ritch actually funded the trusts nor any evidence to show from whence the substantial assets owned by BRT originated. Ranter’s assertion that he merely ceded investment opportunities in Cablevision to BRT does nothing to undermine the Tax Court’s findings and, further, depends on his credibility, which the court found to be lacking. Because Ranter was the principal source of the funding of BRT, he is deemed a grantor of BRT. See 26 C.F.R. § 1.671-2(e)(1) (“[A] grantor includes any person to the extent such person either creates a trust, or directly or indirectly makes a gratuitous transfer ... of property to a trust.... If a person creates or funds a trust on behalf of another person, both persons are treated as grantors of the trust.”).
Ranter argues that the Tax Court’s finding that he was the grantor is directly contrary to an Illinois trial court decision, in which the Cook County Circuit Court determined that the Cablevision partnership interests did not constitute property of Ranter’s law firm because they did not result from payment of fees for legal services. Statland v. Levenfeld, No. 84 CH 6494 (Ill.Cir.Ct., Ch. Jan. 28, 1988). Ranter argues that (a) the state court ruling stands for the proposition that the Cablevision partnership interests were not in payment for any services (not just legal services) but were rather investments and (b) the state court ruling is determinative and binding on the matter. Ranter overstates the holding of the cited case. The case involved a former law partner of Ranter, who alleged that the Cablevision partnership interests were the property of the partnership because they were provided in payment for legal services. The Illinois court disagreed and held that the Cablevision partnership interests were not the product of legal fees paid to Ranter’s law firm. The court did not hold, however, that the Cablevision partnership interests were not in payment of fees for services furnished by individual law firm partners in securing financing and investors for Ca-blevision, which is what the Commissioner alleges here. The trial court did, at various times, refer to the Cablevision partnership interests as individual investments, but it also spoke of the activities of Ranter and his partners in working to obtain financing and investors for Cablevision. None of these dicta contradicts the position of the Commissioner nor renders the factual findings of the Tax Court clearly erroneous.
4. Ranter was the substantial owner of BRT
Generally, if a grantor of a trust has the power to dispose of the beneficial enjoyment of that trust through a power of appointment, then the grantor is treated as the owner of the trust and the income of the trust must be included in the income of the grantor. 26 U.S.C. §§ 671, 674(a); 26 C.F.R. § 1.674(a)-1. Ranter argues that he three times renounced his beneficial interest in BRT and, by those renunciations, lost the power of appointment that he had under the trust document. But the Tax Court notes that, after the third of Ranter’s renunciations, sixty new beneficiaries *854were added to BRT.19 Kanter was the only-person who ever had the power under the trust document to appoint new beneficiaries. The most logical inference (which the Tax Court drew) is that Kanter himself appointed the new beneficiaries and that his earlier renunciations were shams. Kanter fails to rebut this. Kanter’s only-argument directly on this issue appears in his reply brief, in which he argues that the Tax Court improperly refused to reopen the record to admit evidence that Kanter’s children were the grantors of the various JSK Trusts that had been added as beneficiaries of BRT.20 (Reply Br. at 18.) This purported evidence would not be probative of the issue whether Kanter had exercised the power of appointment under BRT. The Tax Court’s findings that Kanter was the grantor of BRT and that he held a power of appointment of beneficiaries of BRT were not clearly erroneous. Therefore, the Tax Court’s finding that Kanter is taxable on BRT’s income in 1986 (and 1987) is also not clearly erroneous.
As an alternative, the Tax Court also found that Kanter’s borrowing from BRT without repayment and without adequate security subjected Kanter to liability for BRT’s income. See 26 U.S.C. § 675(3) (“The grantor shall be treated as the owner of any portion of a trust in respect of which .... [t]he grantor has directly or indirectly borrowed the corpus or income and has not completely repaid the loan, including any interest, before the beginning of the taxable year.”). It appears undisputed that Kanter had borrowed money from BRT in a way that subjects him to liability under § 675(3), and that at the beginning of 1987 he still owed BRT $287,030. This would be sufficient for Kan-ter to incur liability for 1987.21 There are, however, no findings by the Tax Court as to any amount Kanter owed to BRT as of January 1, 1986. Therefore, there could be no tax liability for Kanter in 1986 based on § 675(3). In the end this conclusion does not affect ultimate tax liability because under § 674 Kanter remains liable for both 1986 and 1987.
In conclusion, we affirm the Tax Court’s determination that Kanter was the grantor of BRT in 1986 and 1987 and is taxable on BRT’s income for those years.
IV. George Washington Painting
A. Facts
In 1980, Kanter was approached by Richard Feigen, a client, who wanted help *855in securing funding to buy a painting of George Washington located in England that Feigen believed to be by John Trumbull.22 Kanter put Feigen in touch with another client, Mr. Rappaport,23 in Switzerland, who agreed to finance the purchase of the painting. The transaction closed. After the purchase, the painting was discovered not to be a Trumbull, and the seller agreed to rescind the sale. As a result of exchange rate and interest rate changes, Rappaport, who had advanced the funds, lost money. Rappaport wanted to be made whole, and when rebuffed, threatened to sue Feigen and Kanter for his claimed loss. Kanter, in convincing Feigen to reimburse Rappaport, agreed to provide $94,231 of his own funds. Kanter also paid $10,000 in legal fees incurred throughout the course of the transaction.
On his 1980 tax return, Kanter claimed the sum of $104,231 as a deduction on Schedule C, stating that his main business activity was “buying and selling paintings.” The IRS disallowed the claimed loss. The Tax Court found, based on Kanter’s testimony, that Kanter’s main occupation was as an attorney and that he did not hold himself out as an art expert or art dealer. This made the claimed deduction unrecognizable under 26 U.S.C. § 162 as an ordinary and necessary business expense. Additionally, the Tax Court did not allow this deduction as a § 212 expense for production of income “because Kanter received no fees and no contract existed therefor, [and so] the expenditure did not bear a reasonable and proximate relationship to the production of income.” IRA, 78 T.C.M. (CCH) at 1121. “[Kanter] merely served as an intermediary to introduce Feigan to another friend, Rappaport. There was no written contract between Feigan and Kanter for the sharing of profits.” Id.
B. Analysis
The Commissioner’s determination that Kanter’s expenses associated with the failed sale of the Washington painting were not legitimate deductions under 26 U.S.C. §§ 162 and 212 is a finding of fact that we review for clear error. Reynolds v. Comm’r, 296 F.3d 607, 615 (7th Cir.2002); Buelow v. Comm’r, 970 F.2d 412, 415 (7th Cir.1992).
The Tax Court found, essentially, that Kanter could not deduct the expenses under §§ 162 and 212 because Kanter’s business was the practice of law, not art, and there was no evidence that Kanter had an agreement with Feigen to receive fees or share profits from the purchase and planned resale of the painting. The Tax Court simply did not believe the “self-serving and uncorroborated” testimony of Kanter. IRA 78 T.C.M. (CCH) at 1121. Given the totality of the Tax Court’s findings that Kanter systematically engaged in extensive (non-law related) business dealings whereby he “entered into arrangements pursuant to which he would use his ... contacts ... to assist individuals ... in obtaining business opportunities or in raising capital for business ventures[,]” we find it implausible for the Tax Court to conclude that Kanter was not engaged in such dealings when he helped Feigen se*856cure financing from Rappaport. IRA, 78 T.C.M. (CCH) at 970.
Without excessively detailing the transactions relating to the Five that we summarized in Part II, we note that the Tax Court’s opinion went to considerable lengths to confirm deficiencies against Kanter based on a characterization of Ranter’s “business” as ranging far beyond the simple practice of law. In each of the transactions involving the Five, the foundation for the Tax Court’s determination that Kanter consistently understated his income was its findings that time after time Kanter provided non-legal business services in facilitating business opportunities for the Five with Prudential, and that he was paid handsomely for that facilitation. It is difficult for us to read the first few hundred pages of the Tax Court’s opinion and not be left with the distinct impression that the Tax Court believes Kanter was involved in this business “activity with continuity and regularity and ... [his] primary purpose for engaging in the activity [was] for income or profit.” Comm’r v. Groetzinger, 480 U.S. 23, 35, 107 S.Ct. 980, 94 L.Ed.2d 25 (1987). At the very least, Kanter has shown a distinct proclivity to seek income and profit through activities similar to the failed sale of the painting.
Determining whether an activity was engaged in for profit requires an examination of the relevant factors outlined in Treasury Regulation 1.183-2. See 26 C.F.R. § 1.183-2; Burger v. Comm’r, 809 F.2d 355, 358 (7th Cir.1987). The nine factors for determining whether Ranter’s involvement in the sale of the George Washington painting was carried on for profit include: (1) the manner in which the taxpayer carries on the activity; (2) the expertise of the taxpayer; (3) the time and effort expended by the taxpayer in carrying on the activity; (4) the expectation that assets used in the activity may appreciate in value; (5) the success of the taxpayer in carrying on other similar or dissimilar activities; (6) the taxpayer’s history of income or losses with respect to the activity; (7) the amount of occasional profits, if any, which are earned; (8) the financial status of the taxpayer; and (9) elements of personal recreation or pleasure in carrying on the activity. 26 C.F.R. 1.183-2(b).
We can, based on Ranter’s testimony and considering the Tax Court’s other findings, construct a highly probable scenario under which Kanter was to find financing for Feigen’s purchase in exchange for part of the anticipated profits. Under factor (1), this manner of doing business, while not well documented, is consistent with the method pursued in other transactions detailed by the Tax Court. Under factor (2), Ranter’s apparent expertise in facilitating financing transactions and putting people together for deals in order to generate income was so evident to the Tax Court that it found him liable for large underpayments of income tax. Additionally, Kanter has indicated that the art project was attractive because of Feigen’s expertise in generating sufficient publicity and excitement about artwork to likely increase the resale price, thus satisfying factor (4). (Tr. at 4416-30.) Regarding factor (5), Ranter’s obvious success in other facilitation-of-business ventures was what landed him in trouble with the Commissioner in the first place. An appealing tale of the Washington painting scheme as a failed for-profit venture emerges from this evidence. In fact, while there is significant evidence that Kanter undertook similar, though not identical, transactions as the failed painting purchase for profit, there is no evidence that Kanter facilitated any other deals of this kind for personal reasons (i.e., gratuitously). And the Commissioner presents no evidence contradicting Ranter’s version of events. In fact, by *857asserting that, in all of his other disputed transactions in which income was produced, Kanter had participated in the manner alleged here and with the kind of profit motive he alleges here, but arguing that in this single transaction, where losses were generated, Kanter participated for only personal reasons, the Commissioner appears to want to have his cake and eat it too.
There are certain difficulties in reversing the Tax Court here. We would have to reverse the Tax Court’s credibility finding on the matter. In that connection, neither Feigen’s testimony, nor Rappaport’s testimony, nor any piece of specific evidence exists in the record to support Kanter’s testimony. And we have found elsewhere that, while a taxpayer’s uncontradicted testimony was sufficient to demonstrate that the Commissioner’s determination was erroneous, the Tax Court can disregard that testimony if it is not credible. Lerch v. Comm’r, 877 F.2d 624, 681 (7th Cir.1989). The Tax Court did not here believe Kan-ter’s claim of a profit motive. While finding Kanter not credible in this instance is consistent with the Tax Court’s refusal to find him credible on other issues, it results in a completely inconsistent and implausible factual scenario — Kanter’s incurring more than $100,000 in expenses gratuitously to facilitate a business transaction where huge potential profits lie. But without any indication why this transaction is unique among all the other Kanter activities, we think the Tax Court was clearly erroneous in rejecting Kanter’s claim that he was pursuing commercial objectives here as elsewhere.
In conclusion, we find that there must have been a profit motive in Kanter’s involvement in the aborted purchase of the George Washington painting; the Tax Court’s finding to the contrary is clearly erroneous and we reverse. Kanter’s deduction for the $104,281 of expenses incurred in facilitating the failed sale of the George Washington painting is allowed.
V. Bank Deposit Analysis
A. Facts
In examining Kanter’s 1982 tax return, the IRS determined that inadequately documented deposits into three of Kanter’s bank accounts during that year greatly exceeded the income Kanter reported on his federal tax return. Based on a comparison of the deposit amounts to Kanter’s tax return for 1982, the Commissioner determined that Kanter had unreported gross income that year in an amount of $2,084,017, and issued an assessment of deficiency. After Kanter produced sufficient records documenting some of the deposits in question, the Commissioner reduced this deficiency to $1,303,207, which comprised the sum of four specific deposits:
DEPOSIT AMOUNT PAYOR OR SOURCE
$787,129 The Holding Co. (THC) 24
$ 40,000 Computer Placement Services, Inc. (CPS) 25
$190,078 Administration Co. (Special E Account)
$286,000 Administration Co. (Special Account)
*858The Tax Court found that the Commissioner had produced sufficient evidence to create a presumption of correctness in the indicated deficiency. The bank deposit analysis method was a reasonable method of reconstructing income, and deposits from THC, CPS and the Administration Co. accounts often included taxable income. Therefore it was proper, the Tax Court ruled, for the Commissioner to determine gross income from an analysis of total deposits to Ranter’s bank account minus any deposits properly excluded from income and to assess a deficiency for the excess of that income over the reported income. The Tax Court found that Ranter had not adequately documented that the four deposits in question were loans, and they were properly included in his gross income under the deposit analysis. Moreover, the Court did not find the testimony of Ranter’s accountant, Gallenberger, credible on the issue.
B. Analysis
The Tax Court’s determination that a taxpayer has unreported income is a finding of fact that we review for clear error. Reynolds, 296 F.3d at 612. The Commissioner’s assessment of a deficiency is presumed correct, but can be overcome by rebuttal evidence presented by the taxpayer. Pittman, 100 F.3d at 1313.
Ranter has three arguments with respect to the deficiency determined by the bank deposit analysis: first, the change in the amount of the deficiency for 1982 under the bank deposit analysis constituted a “new matter” under Tax Court Rule 142 that required the burden of proof to shift to the Commissioner, and with that burden the Commissioner cannot prevail. Second, the lack of evidence on this issue made the deficiency a “naked assessment,” and it was, therefore, improper to give the Commissioner’s assessment of a deficiency the usual presumption of correctness. See Weimerskirch v. Comm’r, 596 F.2d 358, 360 (9th Cir.1979) (finding no presumption of correctness when Commissioner’s assessed deficiency lacks any reasonable foundation in the evidence). Finally, Ranter argues that the Tax Court clearly erred in finding a deficiency in light of the evidence presented. All of these arguments fail.
First, there is no merit in Ranter’s contention that the Commissioner’s reduction in the amount of deficiency assessed in 1982 under the bank deposit analysis is a new matter requiring a shift in the burden of proof. The Commissioner’s concession that part of the original deficiency was properly excluded from Ranter’s income is not a new theory, is not inconsistent with the original assessment of deficiency, does not require new or different evidence from Ranter and does not increase the assessed deficiency. See discussion supra Part III. The same theory of bank deposit analysis was being applied before and after the Commissioner’s concessions, and the resulting deficiency was reduced, not increased, when Ranter produced documentation demonstrating to the Commissioner’s satisfaction that certain deposits were not income. The remaining, insufficiently documented deposits, therefore, do not constitute a new matter.
Nor can Ranter escape the presumption of correctness by relying on the “naked assessment” exception of Weimerskirch. “The general rule is that a presumption of correctness attaches to the Commissioner’s deficiency determination; the taxpayer has the burden of disproving it. A narrow exception exists where the determination is arbitrary and erroneous or without rational foundation.” Pfluger v. Comm’r, 840 F.2d 1379, 1382 (7th Cir.1988) (citations omitted). It is not disputed that “before the Commissioner can rely on [the] *859presumption of correctness, the Commissioner must offer some substantive evidence showing that the taxpayer received income from the charged activity.” Weimerskirch, 596 F.2d at 360. But the threshold for properly invoking the presumption is not as high as Ranter would have us believe, nor is the evidence presented by the Commissioner as thin as that presented in Weimerskirch.
In Weimerskirch, the Commissioner assessed a deficiency based on more than $24,000 of unreported income from the taxpayer’s alleged sale of heroin. Id. at 359. The Commissioner, however, presented no evidence from which one could even infer that Weimerskirch was involved in heroin sales in any way. There were, for example, no records of bank deposits, net worth, or cash expenditures. Id. at 361-62. The deficiency was calculated based on an IRS agent’s purely hypothetical calculation of what income would be realized from a given level of heroin sales each week over a given period of time. Id. at 359. Not only was the deficiency calculation completely divorced from any evidence of actual or inferrable heroin sales by Weimer-skirch, but the entire method of calculation used was unsupported by evidence. Id. The Commissioner’s attempt to attach the presumption of correctness to the assessed deficiency in Weimerskirch was, in every sense of the word, naked.
In contrast, the presumption of correctness in the present ease appears far more modestly appareled. The Commissioner’s use of bank deposits as circumstantial evidence of gross income is an accepted methodology. See, e.g., United States v. Ludwig, 897 F.2d 875, 878 (7th Cir.1990). The Tax Court found evidence that Ranter was engaged in income producing businesses. And the court found that actual deposits were made that had the appearance of income. IRA, 78 T.C.M. (CCH) at 1104; see also United States v. Esser, 520 F.2d 213, 217 (7th Cir.1975) (describing test for implementing deposit analysis method of reconstructing income). There is no dispute about the evidence of deposits. Consequently, there was sufficient evidence to support the presumption of correctness.
Lastly, Ranter argues that the uncontra-dicted evidence at trial shows that the four deposits in question were loans and were not income. By uncontradicted, we can only assume Ranter means uncontradicted by any evidence beyond the evidence we have outlined, establishing, prima facie, that there was a deficiency during 1982. Because we have found that the Tax Court properly gave the Commissioner’s assessed deficiency a presumption of correctness, we must interpret Ranter’s argument as claiming that the evidence presented overcame the presumption. In that respect, Ranter’s argument also fails.
In considering whether Ranter met his burden of proof, the Tax Court found Gal-lenberger’s summary and Ranter’s assertions unconvincing. “No credible evidence was introduced to support Ranter’s assertion that the deposits were loans.... We find the testimony of the accountant, Gal-lenberger, unreliable and her analysis fatally flawed....” IRA 78 T.C.M. (CCH) at 1104. The Tax Court also recalled “Gal-lenberger’s regular practice of record destruction” and the general lack of any documentation other than her summary and testimony. Id. at 1104-05. The evidence that Ranter asserts was “uncontradicted” was considered by the Tax Court and found wanting. Exhibit 9172PR, which, according to Ranter, demonstrates that the deposits from CPS, THC, and Administration Co. were loans, reflects a summary analysis by Linda Gallenberger that the Tax Court found not credible. Nor is it correct for Ranter to say that the Tax *860Court had determined previously that one of the deposits of money from Administration Co. was money already found to belong to Kanter. (Pet. Br. at 58.) Kanter cites to a sentence in the Tax Court’s opinion as to issue 21 (allowable capital gains and losses in 1987) wherein the court states, “As indicated previously, funds from the Administration Co. special E and PSAC special E accounts were Kanter’s funds.” IRA, 78 T.C.M. (CCH) at 1126. This sentence, in context, refers only to the specific funds from the accounts cited and used in the specific transactions at issue (five years after the deposits at issue here) in that section of the Tax Court opinion. These specific funds were Kan-ter’s own funds, and he was entitled, therefore, to the basis he had claimed for the assets he had purchased with those funds. But Kanter seeks to generalize this statement about his ownership of specific money to mean that all the money in the Special E accounts, at all times, already belonged to Kanter. The Tax Court’s opinion does not say this.
In conclusion, the Tax Court did not clearly err in its findings regarding Kan-ter’s unreported income in 1982 as determined by bank deposit analysis. These findings are therefore affirmed.
VI. Equitable Leasing’s Payments to THC & Zion
A. Facts
Equitable Leasing Co., Inc. (Equitable) was the wholly owned company of Joel Mallín, a friend and former law partner of Kanter. Mallín used Equitable (among other companies) to promote and structure equipment leasing transactions to make money for investors. The investors’ capital would be highly leveraged to purchase the equipment to be leased, and the residual value of the equipment at the end of the lease would provide the ostensible paper profit on the investors’ capital. A principal motivation behind the investment in the leasing transactions, however, was the opportunity for tax benefits associated with the venture. Kanter acted as a middleman, introducing Mallín to investors for his leasing transactions. In return, Mallín paid commissions to Kanter entities. The Commissioner issued a notice of deficiency for 1983 that included a deficiency of $635,250 with respect to four payments by Equitable to Kanter entities, Zion, and THC.26
FORM OF DATE PAYMENT PAYEE AMOUNT
Jan. 4, Bank Zion $317,250 198327 Transfer
Jan. 24, Check THC $ 9500 1983
June 1, Check Zion $ 6500 1983
June 30, Bank THC $302,000 1983 Transfer
Total $635,250
The Commissioner alleged that these payments were commissions paid for Kan-ter’s procurement of investors in Mallin’s enterprises. Kanter argued that Zion and THC were loaned money by Equitable that was then turned around and invested in Equitable as an accommodation to Equita*861ble to enable it to close certain transactions.
The Tax Court found that there was sufficient evidence to indicate that Equitable had paid commissions to Zion and THC for Kanter’s services in providing investors to Mallín. Two of the four payments, for $9500 and for $6500, were labeled (on the check in payment and in THC’s adjusting journal entries, respectively) as commissions. The Tax Court determined that this evidence was sufficient to support the presumption that all of these payments to Zion and THC were income to Kanter. In response to this presumption, the Tax Court found that Kanter had provided no evidence other than his “uncorroborated, self-serving testimony” concerning the “accommodation” arrangement with Equitable. IRA, 78 T.C.M. (CCH) at 1103. The court found, as previously noted, that Kan-ter was not credible and that the four payments were income attributable to Kanter.
B. Analysis
Whether or not monies are taxable income to a taxpayer is a finding of fact that we review for clear error. Reynolds, 296 F.3d at 612. The Commissioner’s assessment of a deficiency is presumed correct, but can be overcome by rebuttal evidence presented by the taxpayer. Pittman, 100 F.3d at 1313.
Kanter argues first that the Commissioner’s assessment of a deficiency should not be given the benefit of the presumption of correctness because the Commissioner “failed to provide any evidence connecting Kanter to this income.” (Pet. Br. at 59.) This argument fares no better here than it did when we considered it with respect to the Bank Deposit issue. There was evidence that Mallín and Kanter were partners in various investments, and that Kanter’s law firm had procured investors for Mallin’s Equitable Leasing transactions. (Tr. at 5213-15.) There was also evidence that Mallín had paid commissions for these services to Kanter entities. (Id.) Additionally, at least two of the payments in question were documented as commissions. This was sufficient evidence to provide a rational foundation for the Commissioner’s assessment.. The Commissioner’s assessment appropriately received its presumption of correctness. See Pittman, 100 F.3d at 1313.
Kanter also argues that he has rebutted the Commissioner’s deficiency with evidence that only the $16,000 that was labeled as commissions (comprised of the $9500 and $6500 checks) should be considered commission payments, and the remainder consisted of loans made as an accommodation to Equitable. Even accepting Kanter’s concession that the $9500 and $6500 checks from Equitable Leasing to THC and Zion, respectively, were taxable commission income, we do not believe he has provided sufficient evidence to show that the two bank transfers of $317,350 and $302,000 were loans.
Regarding the $317,250 transfer, there is clearly evidence supporting the Tax Court’s finding that the transfer was a commission paid to Zion, and Kanter has provided no evidence to rebut this finding despite his control of the entities involved and his access to the records of those entities. First, as noted, there was circumstantial evidence that Equitable Leasing was making payments to THC and Zion as commissions. Additionally, THC’s adjusting journal for 1983 has an entry “32” indicating an amount of $317,250 that was labeled, “Due from Zion — Commission Income to adj. for commiss. from Eq. Leasing, loaned to Zion on 1/4/83.” (Ex. 146, THC adjusting journal at 6.) Finally, Kanter appears to concede in the facts section of his brief that this amount was *862received as commission. In his brief on appeal, Kanter breaks down the $635,250 as including “$317,250 as commission income from Equitable (see Ex. 146, THC adjusting journal, p. 6, adjusting journal entry 32, reflecting commission income of $317,250 which was paid to THC’s subsidiary Zion as a loan from THC ...).” (Pet. Br. at 16.) The Tax Court’s finding that this payment was commission income was not clearly erroneous.
What about the June 30, 1983 transfer from Equitable to THC for $302,000? Against the general circumstantial evidence of commission payments to THC by Equitable and the presumption of correctness of the Commissioner’s assessment of deficiency, there is an entry in THC’s general ledger for June 30, 1983, for $302,000 labeled “Loan from Equitable Leasg.” (Ex. 148, THC general ledger at 12.) Together with this entry there is an entry indicating an $8000 transfer three days earlier also labeled “Loan from Equitable Leasg.” (Id.) This $8000 transfer is corroborated by a check from Equitable to THC on June 24, 1983, for $8000 that has a memo line reading, “loan.” (Ex. 9203PK, check #2391.) The corroboration of the general ledger entry for the $8000 transfer is indirectly probative of the likelihood that the roughly contemporaneous and similarly labeled ledger entry for the $302,000 transfer may also be correct. These circumstances make it more likely that the ledger is accurate in its indication that the $302,000 transfer was a loan and not a commission payment.
But there is one additional piece of evidence in the record that the Commissioner and Kanter have not mentioned. In the THC adjusting journal, entry 59 is a barely legible entry for $310,000 that appears to read, “N/P — Equitable Leasing, Commission Income, to reclassify funds from Eq. Leasing.” (Ex. 146, entry 59.) This entry is significant because we believe it may also represent the $302,000 and $8000 transfers and show that those transfers were commissions. These two transfers were roughly contemporaneous, and Kan-ter himself aggregates them and describes them as a cumulative amount in his brief. (See Pet. Br. at 16 (“$310,000 as loans from Equitable ... reflecting a $302,000 loan and an $8,000 loan .... ”).) The $310,000 in entry 59 would appear to be the same as the $310,000 in the general ledger and as the $310,000 described by Kanter, comprising the total of the $8000 and $302,000 transfers. Entry 59 in the THC adjusting journal weighs against the general ledger’s notations for both the $302,000 and the $8000 transfer and weighs further in favor of the Tax Court’s finding that the $302,000 was a commission payment. In any event, this evidence does, at the very least, make the characterization of the $302,000 transfer unclear, and because Kanter bears the burden of rebutting the Commissioner’s assessment of deficiency and controlled the entities whose records could have cleared this matter up definitively, we cannot say that the Tax Court clearly erred in finding that the $302,000 was a commission payment to THC for Kanter’s services.
In conclusion, it was not clear error for the Tax Court to find that the transfers from Equitable Leasing were commissions and were taxable income.
VII. Cashmere Investment Assoc.’s transactions
A. Facts
During the 1970s, Kanter was involved in a series of real estate developments with developer Sam Zell. The development properties were owned by partnerships (real estate partnerships). Kanter’s interests in the real estate partnerships were held through a series of Kanter-controlled *863trusts, including the BWK Revocable Trust, the Everglades Trusts 1-5, and the BWK Family Trusts (referred to collectively as the grantor trusts). Each of these trusts was a grantor trust whose income was attributable to Kanter personally. A detailed breakdown of the real estate partnership interests and their associated financial attributes is provided in the Tax Court’s opinion. IRA, 78 T.C.M. (CCH) at 1107-11. The interests in these real estate partnerships had, as of 1982-88, zero basis.
During 1982, Zell expressed his desire to purchase all of the real estate partnership interests held by the grantor trusts. Kan-ter was interested in selling to Zell, but was concerned that significant gains would be triggered by an unqualified sale of the real estate partnership interests held by his grantor trusts. The Tax Court found that twenty one of the real estate partnership interests held by the grantor trusts had negative capital accounts; that is, their liabilities exceeded their bases, by an amount, in total, of $476,889. IRA, 78 T.C.M. (CCH) at 1108. Therefore, the unqualified transfer of those interests would involve the assumption of liabilities in excess of the bases, and would trigger capital gains to the seller — Kanter, who was the owner by virtue of the IRC’s grantor trust provisions. See 26 U.S.C. §§ 671-677.
In 1983, a series of transactions took place that ultimately resulted in the transfer of the real estate partnership interests from the grantor trusts to a Zell-controlled entity. The transfer took place in three stages.
1. Transfer of real estate partnership interests to Cashmere
Cashmere Investment Associates, Inc. (Cashmere) was an inactive “shelf’ corporation incorporated in Delaware in 1982 and controlled by Kanter. On or about May 15, 1983, Kanter directed the grantor trusts to transfer their real estate partnership interests to Cashmere in what was intended as a nontaxable exchange under 26 U.S.C. § 351 in return for Cashmere common and preferred stock. Concurrently with the § 351 transfer, the grantor trusts also transferred to Cashmere eight promissory notes payable to, and held by, the grantor trusts with a face value, in total, of $498,500. The promissory notes were all dated May 1, 1983, and were payable on August 1,1983. These promissory notes, according to Kanter, had a basis equal to face value and increases the total aggregate basis of the transferred property so as to eliminate the gain that would otherwise have been realized under 26 U.S.C. § 357(c) through the assumption by Cashmere of the negative capital accounts in the transfer of the real estate partnership interests. See 26 U.S.C. § 357(c).28
2. Sale of Cashmere stock to Waco
On July 12, 1983, in the next stage of the transfers to Zell-controlled entities, Kanter directed the grantor trusts to sell their common and preferred stock in Cashmere to Waco Capital Corp. in return for promissory installment notes totaling approximately $1.5 million. The grantor trusts *864reported the income from this sale under the installment method of 26 U.S.C. § 453.
Waco was a Delaware corporation whose sole shareholder was BRT. BRT’s beneficiaries were the members of Ranter’s family, who were also the beneficiaries of the grantor trusts. The Tax Court found that, under 26 U.S.C. § 453(f), Waco and the grantor trusts were “related persons.” See 26 U.S.C. § 318(a)(2), (3).
On August 31, 1983, the promissory notes held by Cashmere were paid off by eight checks drawn on the Administration Co.’s Special E account. As noted, the Special E account contained the commingled funds of a variety of entities, mostly (if not entirely) Ranter entities, and the Administration Co. accounted internally for the specific source of a given disbursement. The Administration Co.’s general ledger, however, did not specify the source of the eight checks paying the notes. The checks themselves indicate, in part, what entity is the payor of the notes. Three of the promissory notes were ostensibly paid with funds from BRT, an entity that was not the maker of the notes in question, and there was no documentary evidence that BRT was advancing the funds to the makers of the promissory notes or had, in some way, assumed the obligations on the notes. IRA, 78 T.C.M. (CCH) at 1110-11.
As of September 1, Waco held all of the stock in Cashmere, and Cashmere’s assets included the real estate partnership interests and $498,500 in cash (from the note payments).
3. Sale of Cashmere stock from Waco to Zell
Ranter subsequently negotiated the sale of Waco’s Cashmere stock to Equity Financial Management Co. (Equity), an entity controlled by Zell. On September 2, 1983, Waco sold the Cashmere stock to Equity for $1,647,500 payable by check.29 Immediately after the purchase, Zell liquidated Cashmere.
The Tax Court found that this convoluted series of transactions taking place within a three-and-one-half month period that ultimately resulted in the transfer of the real estate partnership interests to Zell was arranged principally to avoid immediate recognition of gain on the transfer and otherwise lacked any bona fide business purpose. IRA, 78 T.C.M. (CCH) at 1113; see 26 U.S.C. § 357(b)(1)(A), (B). Therefore, the assumption of liabilities by Cashmere was recognized as money received by Ranter (through his grantor trusts), and he was required to be taxed on his gain resulting from the transfer, up to the full amount of the liabilities. 26 U.S.C. § 357(b). Additionally, the Tax Court found that the transfer of the notes with the real estate partnership, interests also lacked any bona fide business purpose and were principally intended as a means to avoid income tax. The Tax Court found that the notes represented mere transfers between and among Ranter-controlled entities, and did not represent true indebtedness. Therefore, Ranter had no basis in the notes, and the notes did not, therefore, increase the aggregate basis in the property transferred to Cashmere. Under § 357(c), the excess of liabilities over basis in the transferred property was therefore recognized as capital gain to Ranter. Because the basis in the partnership interests was zero, under both § 357(b) and (c), the full amount of the transferred liabilities was taxable to Ranter.
*865Additionally, the Tax Court found that the subsequent sale to Waco using the installment method was a “disposition] of property to a related person.” 26 U.S.C. § 453(e)(1)(A). When Waco then subsequently transferred, within two years, the Cashmere stock to Equity, the installment method of reporting was no longer available. 26 U.S.C. § 453(e)(1), (2). The entire amount realized by Waco in the second disposition was treated as received (at the time of the second disposition) by the seller-grantor trusts in the first disposition. Id.
B. Analysis
Whether the transactions involving Cashmere had economic substance for federal income tax purposes is a factual question reviewed for clear error. N. Ind. Pub. Serv. Co. v. Comm’r, 115 F.3d 506, 510 (7th Cir.1997). Similarly, whether the installment method of reporting is available is a factual question that we review for clear error. Applegate v. Comm’r, 980 F.2d 1125, 1128 (7th Cir.1992).
1. The Attempted § 351 Transaction
The tax-free transfer of property to a controlled corporation solely in exchange for the transferee corporation’s stock is permitted under 26 U.S.C. § 351. The IRC also provides a means for preserving § 351 eligibility in circumstances where the transferee corporation assumes liabilities of the transferor together with the property transferred (an event that is economically equivalent to a transfer of money (boot) from the transferee corporation to the property transferor). 26 U.S.C. § 357. There are two limitations, however, to tax-free treatment under § 351. First, the taxpayer-transferor must prove by a preponderance of the evidence that the liabilities were not transferred for the principal purpose of tax avoidance and that the transfer had a bona fide business purpose. § 357(b). If the taxpayer fails to clear this hurdle, the assumption of the liability is treated as money received by the taxpayer, and the taxpayer recognizes any gain to the full amount of the liability. 26 U.S.C. §§ 357(b)(1), 351(b)(1)(A). Second, if the amount of the liability transferred is greater than the basis of the property transferred, then, in general, the transferor-taxpayer recognizes a capital gain on the amount by which the liability exceeds the basis of the transferred property. 26 U.S.C. § 357(c)(1).
a. 26 U.S.C. § 357(b)
There can be little question that the Tax Court was correct when it viewed the totality of the convoluted Cashmere transactions and found that their only purpose was the avoidance of federal income tax. Ranter’s argument that § 357(b)(1) does not reach this transaction is merit-less. Within a four-month period of time an inactive shelf corporation controlled by Ranter (Cashmere) had its stock transferred three times, twice between Ranter-controlled entities. Within that same time span, promissory notes, virtually equal in total value to the total negative capital account balances, were made by entities controlled by Ranter, transferred (along with the real estate partnership interests holding the negative balances) to entities controlled by Ranter and then satisfied by entities controlled by Ranter. Both Cashmere and the promissory notes completed their entire useful life-cycle within the span of the larger, intended transaction— transferring the real estate partnership interests to Zell. Yet neither the promissory notes nor Cashmere functioned to facilitate the transfer of the real estate partnership interests to Zell: the promissory notes were created, transferred, and satisfied before the consummation of the sale to Zell, and Cashmere was liquidated as soon as *866its stock came into Zell’s possession leaving Zell with only the desired asset — the real estate partnership interests. The entire transaction was constructed to avoid the recognition of the gain realized on the assumption of the real estate partnerships’ liabilities (by, ultimately, Zell). Therefore, the assumption of those liabilities by Cashmere in the initial stages of the process cannot be described as other than having as its principal purpose the avoidance of federal income tax. See 26 U.S.C. § 357(b).
Ranter’s remaining argument with respect to § 357(b) appears to be that the intent of that statutory section was to prevent taxpayers from creating additional liabilities (like personal loans or debts) to be packaged with assets contributed in a § 351 exchange in order to extract the gains contained within the contributed property without recognition for tax purposes. This kind of intent to avoid taxes, argues Ranter, is far removed from the present case where the liabilities were a substantial aspect of the real estate partnership interests to be contributed. This argument fails as well. The fact that the liabilities being contributed were “ordinary business liabilities of the partnerships” does nothing to save this transaction. As noted, the entire business of contributing the partnership interests and their associated liabilities to Cashmere was a transaction whose only function was the avoidance of federal tax. Therefore, “taking into consideration the nature of the liability and the circumstances in the light of which the arrangement for the assumption was made,” it is clear that the principal purpose of the assumption of liabilities was the avoidance of tax. 26 U.S.C. § 357(b)(1).
it was not clearly erroneous for the Tax Court to have found that the assumption of the real estate partnership interests’ liabilities by Cashmere had as its principal purpose the avoidance of federal income tax.
b. 26 U.S.C. § 357(c)
The Tax Court also found, alternatively, that § 357(c) would apply to the Cashmere transactions.30 Section § 357(c) is triggered when the amount of the liabilities assumed exceeds the basis of the property contributed in the § 351 exchange. The taxpayer is taxed on the amount by which the liabilities exceed the basis. The Tax Court found that the contributed promissory notes did not represent genuine indebtedness and had, therefore, a basis of zero. Without any additional basis from the promissory notes, the basis of the contributed real estate partnership interests was zero, and the amount of the liabilities assumed (in the form of the oft-mentioned negative capital accounts) necessarily exceeded that zero basis. Therefore, the gain realized in the § 351 transfer must be recognized to the full extent of the assumed liabilities.
Ranter vigorously argues that the substance of the promissory notes should be respected and not disregarded as mere form, and the notes should be given a basis equal to their face value. For this argument Ranter relies heavily on the Ninth Circuit’s determinations in Peracchi v. Comm’r, 143 F.3d 487 (9th Cir.1998), where a taxpayer made and contributed notes to his closely held corporation. The Ninth Circuit found substance in Perac-chi’s promises to pay himself, and increased the basis of property contributed (in a § 351 exchange) to a figure greater *867than the liabilities assumed by the closely-held transferee corporation. Id.; see also Lessinger v. Comm’r, 872 F.2d 519 (2d Cir.1989) (finding also that personal note had face-value basis in hands of transferee corporation). The hypothetical risk that this note might somehow become the property of a creditor (through bankruptcy of the corporation) and that a creditor might then be able to enforce the note was sufficient to make the note more than an empty promise. Peracchi, 143 F.3d at 493. The Ninth Circuit panel realized the potential for abuse of this holding, however, and cabined it.
We confíne our holding to a case such as this where the note is contributed to an operating business which is subject to a non-trivial risk of bankruptcy or receivership. [The closely held company] is not, for example, a shell corporation or a passive investment company.
Id. at 493 n. 14.
Even if we were to accept Peracchi’s underlying premise that a taxpayer’s self-made obligations to his own closely held corporation should be respected for tax purposes, in light of the language limiting Peracchi’s holding, we would not extend that premise to the present case. Cashmere was a passive investment company that, before the transactions at issue, was a shelf corporation. And after the transfer of the real estate partnership interests to Zell, Cashmere was liquidated. Cashmere was not an operating business, and, unlike Peracchi, where an insurance corporation needed more assets to meet a minimum premium-to-asset ratio-for regulatory purposes, there was no underlying business purpose here for these transitory promissory notes. Nor did Cashmere face a “non-trivial risk of bankruptcy.” Perac-chi is, therefore, quite distinguishable from the present case. The promissory notes here did not represent genuine indebtedness, and the Tax Court did not clearly err in finding that the promissory notes had no basis. Therefore, the Tax Court’s conclusion that the liabilities assumed exceeded the basis of the contributed property by the full amount of the liabilities and were taxable to that extent was not clearly erroneous.
2. Disallowance of § 453 Installment Method
The next steps in the sale of the real estate partnership interests to Zell involved, first, the sale of the Cashmere stock from Ranter’s grantor trusts to Waco and, second, the subsequent sale within two months of the Cashmere stock from Waco to Equity (the Zell-controlled entity). The grantor trusts reported their gains from the sale to Waco under the installment method allowed by 26 U.S.C. § 453.31 But § 453(e) limits the use of the installment method in circumstances where there is a second disposition of the property within two years that is effected by a person “related” to the original seller. In other words, if A sells to B, and then B sells to C (within two years), A cannot report the income from its sale under the installment method if A and B are “related persons” under 26 U.S.C. §§ 267(b) or 318(a). The Tax Court found that the grantor trusts and Waco were “related persons,” and that the entire amount of income attributable to the sale of the Cashmere stock to Waco must be recog*868nized in 1983. We affirm this finding as well.
Section § 453(f)(1) defines a “related person” for purposes of determining the reach of § 453(e):
(A) a person whose stock would be attributed under section 318(a) (other than paragraph (4) thereof) to the person first disposing of the property, or
(B) a person who bears a relationship described in section 267(b) to the person first disposing of the property-
26 U.S.C. § 453(f)(1). Waco’s stock is owned entirely by BRT, whose beneficiaries were undisputedly the members of Ranter’s family. Similarly, Kanter does not dispute that these same family members were the beneficiaries of the grantor trusts. Under 26 U.S.C. § 318(a)(2)(B)(i), the stock owned by BRT is considered owned by its beneficiaries. Therefore, the BRT beneficiaries are treated as owning the Waco stock. Similarly, those same BRT beneficiaries are also beneficiaries of the grantor trusts, and their ownership of the Waco stock is imputed “upstream,” under § 318(a)(3)(B)®, to the grantor trusts. Therefore, the stock of Waco would be attributed to the grantor trusts under § 318(a), making Waco a person “related” to the grantor trusts under § 453(f)(1)(A). The attribution, therefore, makes the sale of the Cashmere stock to Waco ineligible for the installment method under § 453(e).32
Similarly, as noted in Part III, Kanter was the substantial owner of BRT under the grantor trust provisions of 26 U.S.C. §§ 671 et seq. Therefore, there is an alternative means by which the grantor trusts and Waco are “related persons.”33 Under § 318(a)(2)(B)(ii), stock owned by a grantor trust is attributed to its grantor; BRT’s stock, therefore, is attributed to Kanter. That is, Kanter himself is considered to own the Waco stock owned by BRT. Following a similar statutory path as before, Ranter’s status as the substantial owner of the grantor trusts means that any stock he owns personally is attributed to the grantor trusts under *869§ 318(a)(3)(B)(ii). Therefore, Ranter’s attributed ownership of the Waco stock means that the grantor trusts also own the Waco stock. Because the grantor trusts are attributed ownership of the Waco stock under § 318(a), Waco and the grant- or trusts are “related persons” under § 453(f)(1)(A), and the sale of the Cashmere stock from the grantor trusts to Waco is ineligible for reporting under the installment method by operation of § 453(e).
Whether one, the other, or both methods of analysis are followed, the grantor trusts’ sale of Cashmere stock to Waco was ineligible for the installment method of reporting for federal income tax purposes. The Tax Court’s findings on this issue were not clearly erroneous.
VIII. Naomi Ranter motions
A. Facts
On May 8, 2001, in the midst of the Tax Court’s post-trial Rule 155 computations, attorney Karen Hawkins entered an appearance in the Tax Court on behalf of Ranter’s wife, Naomi Ranter (Naomi), for the purpose of claiming that Naomi should not be jointly and severally liable for the Tax Court’s determined deficiencies against Ranter. Shortly thereafter, Randall Dick, attorney of record for both Ranter and Naomi, moved to withdraw his representation of Naomi. By her new counsel, Naomi first filed a series of objections to the Commissioner’s computations because they held Naomi liable for fraud penalties. The Tax Court upheld these objections. (Order, IRA, 6/20/01; App. at 0346.) Naomi then filed seven motions asking the Tax Court to find that she had not meaningfully participated in the litigation as provided in 26 U.S.C. § 6015(g)(2). In the alternative, Naomi asked that the Tax Court reopen the record in order to hear additional evidence that Naomi was an “innocent spouse” under 26 U.S.C. § 6015(b) and § 6015(f), and not jointly and severally liable with her husband. In response to Naomi’s motion, the Commissioner stated that “respondent has no objection to petitioner’s first request for relief [a finding that Naomi had not meaningfully participated in the litigation].” (See App. at 0364.) Therefore, the Commissioner felt the alternative request to reopen to hear additional evidence that Naomi was an innocent spouse was moot.
In its September 20, 2001 Order, the Tax Court denied Naomi’s seven motions. (See App. at 0224.) The Tax Court found that the language of § 6015(g)(2) required that any finding that a spouse had not “meaningfully participated” in the litigation must occur in a subsequent, separate proceeding that could properly consider the matter now before us as a “prior proceeding.” 26 U.S.C. § 6015(g)(2). Therefore, the Tax Court ruled, Naomi would have to wait for a separate proceeding before the Tax Court to have the res judi-cata effect of the present case adjudicated. Additionally, thé Tax Court exercised its discretion not to reopen the record and take additional evidence on the merits of Naomi’s claim that she was an “innocent spouse.” The Tax Court found that, even though the innocent-spouse provisions had been significantly amended in 1998, and clarified in 2000, the underlying availability of innocent-spouse relief had been unchanged since the origination of the present case in the early 1990s. The court refused to reopen a case whose trial had concluded more than five years earlier, especially when there had been no mention of innocent-spouse relief during the period since the trial. Given the possibility of later relief for Naomi in a subsequent proceeding, the Tax Court did not feel the burden on the Commissioner to reopen the *870present case and litigate the issue was justified.
B. Analysis
This court reviews the denial of motions to reopen the Tax Court’s record for abuse of discretion. Coleman v. Comm’r, 16 F.3d 821, 829 (7th Cir.1994). Whether or not § 6015(g)(2) requires a subsequent proceeding to determine whether Naomi had “meaningfully participated” in the matter now before us as a “prior proceeding” is a question of statutory interpretation that we review de novo. Eli Lilly & Co. v. Natural Answers, Inc., 233 F.3d 456, 467 (7th Cir.2000).
The substance of current 26 U.S.C. § 6015 was enacted as part of the Internal Revenue Service Restructuring and Reform Act of 1998, Pub.L. No. 105-206, 112 Stat 685, § 3201 (IRRRA). Technical corrections to the IRRRA were enacted in 2000, leaving us with the statute as it presently appears. See Community Renewal Tax Relief Act of 2000, Pub.L. No. 106-554, 114 Stat. 2763, App. G. Section 6015 contains the so-called “innocent spouse” provisions that allow a spouse to avoid joint and several liability for a tax deficiency assessed against both husband and wife based on a joint tax return filing. To avoid joint and several liability, the innocent spouse must show, generally, that (1) a joint return was filed, (2) the return understated the tax owed based on the “erroneous items” of the other joint filer, (3) she did not know, and had no reason to know, that there was an understatement, (4) it is inequitable to hold her liable for the understatement and (5) she has applied for innocent-spouse protection no later than two years after the Commissioner begins “collection activities.” See 26 U.S.C. § 6015(b). Section 6015 expanded previous innocent-spouse provisions by removing the requirement that the understatement be “substantial” and that the return be “grossly erroneous” in order to receive protection. Additionally, § 6015 provided increased protection for divorced or separated spouses by holding such a spouse liable for only those items on which she would have been liable had she filed a separate return. Finally, the modifications to § 6015 provided for equitable relief for an innocent spouse. 26 U.S.C. § 6015; see also John B. Harper, Federal Tax Relief for Innocent Spouses: New Opportunities Under the IRS Restructuring and Reform Act of 1998, 61 Ala. Law. 204 (2000).
Section 6015 also contemplates the possibility that a court will adjudicate a joint tax liability to completion before an innocent spouse invokes the section’s protection. Under § 6015, res judicata will attach to the decision of a court if the innocent spouse “participated meaningfully in [the] prior proceeding,” even if the innocent-spouse issue was never presented to the adjudicating court. 26 U.S.C. § 6015(g)(2).
Naomi first argues that the Tax Court should have “determined,” under § 6015(g)(2), that she did not meaningfully participate in the Tax Court litigation and that the Tax Court’s IRA decision against her husband would have had no preclusive effect with respect to her potential innocent-spouse defense to joint liability. Naomi argues that the record and the Tax Court’s decision clearly show that she was not involved in the present case. See IRA, 78 T.C.MJCCH) at 969 (“Petitioner Naomi R. Ranter, Ranter’s wife, was not involved in any of the activities giving rise to this litigation. However, she filed joint Federal income tax returns with Ranter for the years at issue.”). She further notes that there would likely not be any delay in the course of the present case with such a determination, that there would be no need *871to reopen the record in order to make such a determination, and that the Commissioner expressly noticed no objection to such a determination.
Unfortunately for Naomi, the general principles of res judicata and the language of the statute deny her this relief at this time. Section 6015(g)(2) is only properly invoked in a subsequent judicial proceeding to avoid the preclusive effect of a prior judicial determination, and has no application during the pendency of the initial judicial proceeding whose preclusive effect she wishes to avoid. First, we start with the plain language of the statute. Lara-Ruiz v. INS, 241 F.3d 934, 940 (7th Cir.2001). As the Tax Court observed, the plain language of § 6015(g)(2), which is labeled “Res judicata,” limits its effect to consideration of a “decision of a court in any prior proceeding,” to determine if an “individual participated meaningfully in such prior proceeding.” To us, this language is clear: a decision from a prior proceeding means that this statute is only applicable when the original court proceeding determining tax liability has concluded. We can only conclude that this section is designed to assist innocent spouses in avoiding the preclusive effect of the other spouse’s prior, completely adjudicated court case, but that the section has no application internal to the prior judicial proceeding.
This reading gains support from the general principle of res judicata. Res judicata prevents parties from relitigating claims that have already been adjudicated by a court to a final judgment on the merits. Of necessity, res judicata requires two proceedings: an original proceeding wherein a final judgment on the merits is rendered, and a subsequent proceeding wherein a party seeks to litigate again a claim decided in the original proceeding. See N.H. v. Me., 532 U.S. 742, 748, 121 S.Ct. 1808, 149 L.Ed.2d 968 (2001) (“Claim preclusion [res judicata] generally refers to the effect of a prior judgment in foreclosing successive litigation of the very same claim, whether or not relitigation of the claim raises the same issues as the earlier suit.”) (emphasis added); see also Black’s Law DICTIONARY 1305 (6th ed.1990) (defining res judicata as the “[r]ule that a final judgment rendered by a court ... constitutes an absolute bar to a subsequent action involving the same claim.”) (emphasis added). Therefore, Naomi cannot have the level of her meaningful participation (or lack thereof) in the present case determined until res judicata becomes relevant in a subsequent proceeding.
In the alternative, Naomi argues that, if she must wait for a subsequent proceeding before § 6015(g)(2) becomes relevant, she wants to have her innocent-spouse defense to joint liability (under 26 U.S.C. § 6015(b) & (f)) adjudicated on the merits during the pendency of the present case. This would require, she argues, reopening the record and allowing her to introduce the necessary evidence to support her innocent-spouse claim, and she further claims that it was an abuse of discretion for the Tax Court not to allow her to do so.
Naomi seeks support in prior Tax Court decisions that, she claims, have “bifurcated proceedings” in order to allow an innocent spouse to have issues of joint liability tried proximately to the general issues of tax liability. (Pet. Br. at 78.) Yet in none of the cases upon which Naomi relies did the innocent spouse remain silent for the duration of the Tax Court proceedings (with over ten years elapsing from Ranter’s petition to Naomi’s first motion regarding this issue) and, only after the case was all but closed, raise, for the first time, an innocent-spouse defense to joint liability. In Vetrano v. Comm’r, 116 T.C. 272, 2001 WL 423012 (2001), the inno*872cent-spouse defense was asserted in the original petition to the Tax Court. Id. at 274. Likewise, both spouses in Charlton v. Comm’r, 114 T.C. 333, 2000 WL 626760 (2000), asserted in their original petitions that they qualified for innocent-spouse relief. Id. at 338. In King v. Comm’r, 116 T.C. 198, 2001 WL 356124 (2001), the original petition was, in its entirety, an innocent-spouse defense, and the so-called not-innocent spouse was involved as an inter-venor. The one consistent thread running through all of these cases relied upon by Naomi is that the request for innocent-spouse relief was squarely before the Tax Court well before the resolution of the case. Naomi, for whatever reason, never put the Tax Court on notice that she had an innocent-spouse defense to joint liability-
Naomi claims her silence was due, in part, to a conflict of interest with respect to the joint representation by counsel of her and her husband. This conflict of interest, she alleges, is the kind of extraordinary circumstance that makes refusing to reopen the record an abuse of discretion. What Naomi fails to argue adequately, however, is that there was an actual conflict of interest. Joint representation, by itself, is not a conflict of interest; the representation of one client must actually conflict with the representation of the other. See United States v. Fox, 613 F.2d 99, 102 (5th Cir.1980) (“However, an actual, not merely hypothetical or speculative, conflict must be demonstrated before it can be said that an accused has been deprived of effective assistance of counsel.”); cf. Dorchester Indus., Inc. v. Comm’r, 108 T.C. 320, 339, 1997 WL 210795 (1997) (“Certainly, one spouse’s claim that she (he) is an innocent spouse can present a conflict of interest to counsel trying to represent both spouses. If, indeed, the spouses do have differing interests with respect to any issue in a case, our rules provide that counsel must secure informed consent of the client, withdraw from the case, or take whatever other steps are necessary to obviate the conflict of interest.”). Naomi shows no actual conflict in the joint representation of her and her husband during the present case. If Naomi could point us to an innocent-spouse defense that she had at any time during the trial, before a decision by the Tax Court, that would have relied upon arguments in conflict with Ranter’s defenses, then she is correct that Tax Court Rule 24(g) may have required separate representation. See Dorchester Indus., 108 T.C. at 339. She has not yet alleged such an argument — in other words, she does not show us that she ever had a viable innocent-spouse defense that she was prevented from raising because it conflicted with Ranter’s defense strategy. There does not appear to have ever been a time when she could say that the joint representation faced conflicting interests between Naomi and Ranter. Now, with the Tax Court’s having entered a final decision, Naomi would have us engage in hindsight and find that she was inevitably prejudiced by the joint representation because she is now liable for deficiencies for which she is the “innocent spouse.” Had Ranter’s arguments succeeded in the Tax Court, she would not be facing joint liability nor would she be alleging conflict of interest. We cannot, and will not, automatically conclude that her silence was helpless ignorance and not a strategic decision.
Naomi is not prejudiced by the Tax Court’s refusal to reopen the record. The opportunity to assert innocent-spouse defenses to joint and several liability remains fully available to her for up to two years after the Commissioner’s first “collection activity.” 26 U.S.C. *873§ 6015(b)(1)(E).34 She will have her asserted defense administratively reviewed by the IRS, and, if necessary and appropriate, judicially reviewed by the Tax Court.35
The Tax Court’s decision not to determine that Naomi had not “participated meaningfully” in the present litigation was proper under § 6015(g)(2), and it was not an abuse of discretion for the court to refuse to reopen the record in order to receive evidence concerning an innocent-spouse defense.
CONCLUSION
In summary:
Issue I — STJ Report. Because we take the Tax Court at its word that in rendering its final opinion it agreed with and adopted the opinion of Special Trial Judge Couvillion, we find Ranter’s arguments challenging the Tax Court’s refusal to disclose the STJ’s “original” report moot. We Affirm the Tax Court’s denial of Ranter’s motions for access to the STJ’s report.
Issue II — Fraud. There is significant circumstantial evidence of fraudulent intent. It was not clearly erroneous for the Tax Court to find fraud.- We Affirm the Tax Court’s findings on this issue.
Issue III — BRT. It was not clearly erroneous for the Tax Court to find that Ranter was the grantor of BRT and to affirm deficiencies against him for BRT’s income during the years at issue. We Affirm the Tax Court’s findings on this issue.
Issue IY — Washington Painting. There can be no question that Ranter sought to facilitate the sale of the George Washington painting for profit. The Tax Court found that, in every instance where the potential for profit was involved, Ranter engaged in significant non-law-related business activities with the purpose of facilitating the business opportunities of others for his own profit. Given the number of evidentiary indicators supporting that this venture was also for profit, we believe it was clearly erroneous to find otherwise. We Reverse the Tax Court’s findings on this issue.
Issue V — Bank Deposits. The Tax Court did not clearly err in its findings regarding Ranter’s unreported income in 1982 as determined by bank deposit analysis. We Affirm the Tax Court’s findings on this issue.
*874Issue VI — Equitable. It was not clear error for the Tax Court to find that the transfers from Equitable Leasing were commissions and were taxable income. We AffiRM the Tax Court’s findings on this issue.
Issue VII — Cashmere. It was not clearly erroneous for the Tax Court to have found that the assumption of the real estate partnership interests’ liabilities by Cashmere had as its principal purpose the avoidance of federal income tax. Alternatively, it was not clearly erroneous for the Tax Court to conclude that the promissory notes did not represent genuine indebtedness and had no basis, and, therefore, that the liabilities assumed exceeded the basis of the contributed property by the full amount of the liabilities and were taxable to that extent. Finally, the Tax Court did not clearly err in finding the grantor trusts’ sale of Cashmere stock to Waco ineligible for the installment method of reporting for federal income tax purposes. We Affirm the Tax Court’s findings on this issue.
Issue VIII — Naomi Kanter. We believe the Tax Court’s interpretation of § 6015(g) was correct, and that Naomi must wait for a subsequent proceeding before she can have the level of her participation in the present case determined. We also do not believe that it was an abuse of discretion for the Tax Court to refuse to reopen the present case to allow Naomi to litigate her innocent-spouse defense. We Affirm the Tax Court on this issue.
For the foregoing reasons we Affirm in part and Reverse in part the decision of the Tax Court.
. Burton W. Kanter died on October 31, 2001. His estate was subsequently substituted as the principal party to this litigation. In order to avoid semantic contortions, this opinion refers interchangeably to the current Petitioners collectively, the Estate of Burton W. Kanter individually and to the late Burton Kanter, as "Kanter.”
. "Tr.” refers to the transcript for the Tax Court trial. "App.” will refer to the appendix to Petitioners' brief.
. All Rule references are to the Rules of the United States Tax Court (Tax Court Rules) unless otherwise indicated.
. The Tax Court trial consolidated the petitions of Kanter and two other individuals (Lisle and Ballard) against whom the Commissioner assessed deficiencies. Under 26 U.S.C. § 7482(b)(1)(A), appeals from Tax Court decisions are reviewed by the U.S. Court of Appeals for the circuit in which the legal residence of the petitioner lies. Of the three petitioners, only Ranter's legal residence lies within the Seventh Circuit. Parallel appeals for the other petitioners are ongoing in the Fifth and Eleventh Circuits. During the pendency of this appeal the Eleventh Circuit issued its opinion. Ballard v. Comm’r, 321 F.3d 1037 (11th Cir.2003).
. Federal Rule of Appellate Procedure 14 states that "[a]ll provisions of these rules, except Rule 4-9, 15-20, and 22-23, apply to review of a Tax Court decision.” Fed. R. App. P. 14.
. Federal Rule of Appellate Procedure 13 provides in relevant part:
(d) The Record on Appeal; Forwarding; Filing.
(1)An appeal from the Tax Court is governed by the parts of Rules 10, 11, and 12 regarding the record on appeal from a district court, the time and manner of forwarding and filing, and the docketing in the court of appeals. References in those rules and in Rule 3 to the district court and district clerk are to be read as referring to the Tax Court and its clerk.
Fed. R. App. P. 13(d)(1). And Federal Rule of Appellate Procedure 10 provides in relevant part:
(a) Composition of the Record on Appeal.
The following items constitute the record on appeal:
(1) the original papers and exhibits filed in the district court;
(2) the transcript of proceedings, if any; and
(3) a certified copy of the docket entries prepared by the district clerk.
Fed. R. App. P. 10(a).
. As the Tax Court opinion notes, there were additional sets of transactions that involved only Lisle and Kanter during Lisle's post-Prudential career at Traveler’s Insurance Company as well as transactions involving Kanter alone. IRA, 78 T.C.M. (CCH) at 970-71. These transactions followed the same pattern detailed here where Kanter used his influence to secure business opportunities for individuals in return for compensation that was then diverted through a series of entities in order to disguise the origin of the funds and avoid income tax liability. For the sake of simplicity we will refer only to the transactions involving Prudential and the Five as representative of all of the transactions detailed by the Tax Court.
. The Five were J.D. Weaver, Bruce Frey, William Schaffel, Kenneth Schnitzer, and John Eulich. The details of the transactions involving the Five are in the Tax Court opinion at 78 T.C.M. (CCH) at 976-1019.
. IRA was originally incorporated in 1974 in Delaware as Cedilla Co. It was intended as a vehicle for making investments. Cedilla changed its name to Investment Research Associates in 1979. IRA owned as relevant subsidiaries, at various times, Carleo, TMT and BWK, Inc. IRA conducted no business and had no employees other than bookkeepers and paid virtually no amount in salaries.
. In 1988, the Administration Co. filed for bankruptcy. Concurrently, a company called Principal Services was organized, and took over many of Administration Co.’s clients, operating with the same purposes and in the same way as had Administration Co.
. Carleo, TMT, and BWK were "shelf” corporations formed by Kanter in 1982. In 1983, they became active, and IRA acquired 100% of the common stock of each. In 1984, each corporation issued shares of preferred stock. Carleo issued its preferred shares to the Christie Trust, a trust established by Kan-ter for the benefit of Lisle’s family. TMT’s preferred shares were issued to the Orient Trust, established by Kanter for the benefit of Ballard’s family. BWK’s preferred shares were issued to the BK Children’s Trust, established for the benefit of Kanter’s family. As part of the scheme, Lisle controlled Carlco’s investment decisions, Ballard controlled TMT’s and Kanter controlled BWK’s.
. The actions summarized in these few sentences took place over many years.
. Kanter's argument that the documents were destroyed according to a standard document retention policy is unpersuasive. The existence of a document retention policy, which appears to have been enforced inconsistently, cannot justify the destruction of documents that were already subject to an IRS summons. Further, we agree with the Tax Court and believe that it is clear from the record that Linda Gallenberger (Kanter's accountant and Administration Co. employee) and Solomon Weisgal (Kanter's associate and trustee/officer for various Kanter entities) acted at the direction of Kanter.
. We speak in generalities in order to avoid further confusing the situation by expanding the alphabet soup of partnership and trust abbreviations, whose exact identities are not necessary to explain the factual background of this issue. The Tax Court’s opinion fully identifies all the relevant entities. See IRA, 78 T.C.M. (CCH) at 1093-1100. We will simply refer to the partnership interests transferred to IRA for Kanter’s services to Cablevision as the Cablevision partnership interests.
. The partnerships in which BRT was a partner sold their respective interests in Cablevision itself, triggering a capital gain to the partnerships that then ilowed-through to BRT. See IRA, 78 T.C.M. (CCH) at 1093.
. A fair reading of the trial transcript is that Kanter’s strategy regarding the BRT income was from the beginning to demonstrate that the income in question had been earned in 1986, not 1987, and to try to shift the burden of proof to the Commissioner in precisely the manner argued here. (Tr. at 4455-4501.) With Kanter’s clear advance knowledge of the calender mistake and his apparent strategic decision regarding that mistake, we find it hard to believe Kanter when he says this "was not an issue that Kanter was prepared to defend at trial” — except inasmuch as this statement may reflect Kanter’s belief at trial that a shifting of the burden of proof to the Commissioner would obviate any need to mount a substantive rebuttal defense.
. The Commissioner appears to be offering to split the baby with respect to the burden of proof issue by conceding that he bears the burden to prove that BRT actually had taxable income in the form of capital gains in 1986, but claiming he has met that burden. There can be no serious dispute that the monies in question were reported as earned in 1986 by BRT. It was Ranter’s own accountant, Gallenberger, who, on redirect by Ranter, provided the testimony with respect to this fact. (Tr. at 4455-4501.) The only substantive issue in dispute is Ranter's status as grantor and owner of BRT under the IRC's grantor trust provisions, a theory unaffected by the amendment.
. This should obviously not be read to preclude the possibility that an amendment of the Commissioner’s pleadings to shift an assessed deficiency from one year to another would result in a shifting of the burden under Rule 142(a)(1). But where, as here, the amendment results from a good faith error in the timing of when specific income was earned from specific transactions and does not involve any change in the underlying theory of the deficiency, there is no shifting of the burden of proof to the Commissioner.
. The new beneficiaries were all trusts— named and numbered variations of "JSK Trust.” IRA, 78 T.C.M. (CCH) at 1094-95.
. A possible logical alternative argument not made by Kanter (because, we must assume, it is not valid) is that the appointments were made by Weisgal under some power he possessed as trustee. The Tax Court, the Commissioner and Kanter all spend significant time arguing whether Weisgal is or is not an independent and adverse trustee. An affirmative determination of that question would be necessary if Weisgal were to have appointed the sixty new beneficiaries or if Kanter were able to prove that he (Kanter) did not appoint them. Because we find that the Tax Court’s determination that Kanter exercised a power of appointment was not clearly erroneous, we need not consider whether or not Weisgal was an independent and adverse trustee of BRT.
.The existence of these facts, however, would raise an additional issue, which we will not attempt to resolve today. Would we, as Kanter claims, need to analyze the amount of the loans in relation to the trust's income during the years the loans were made and from that determine what portion of the trust income from 1987 is attributable to Kanter? See Bennett v. Comm’r, 79 T.C. 470, 484-85, 1982 WL 11148 (1982). Or can we, as the Commissioner urges, merely consider the significant amount of the loans as indicative of Kanter’s total control over BRT’s income and therefore attribute all of the income for 1987 to Kanter? See Benson v. Comm’r, 76 T.C. 1040, 1047-48, 1981 WL 11406 (1981).
. John Trumbull was a painter of scenes and individuals from the time of the founding of the United States. He is, perhaps, most well known to the general public as the painter of the famous "Declaration of Independence” painting that dramatized (more accurately, fictionalized) the scene of the signing of the Declaration of Independence, and that is familiar to almost every American schoolchild from its reprinting in countless American History textbooks.
. Neither the parties’ briefs nor the trial transcript reveal Mr. Rappaport’s first name.
. THC was a Kanter entity incorporated in 1976. Its purpose, like that of IRA, was the making of investments. One of the relevant subsidiaries of THC was Zion Ventures, Inc. (Zion). See infra Part VI. The stock of THC was substantially owned by the BRT and Everglades Trusts 1-5 (Everglades Trusts), which were Kanter trusts whose income was attributable to Kanter via the IRC’s grantor trust provisions, 26 U.S.C. §§ 671 et seq.
. The record does not indicate who holds legal or beneficial ownership of CPS.
. THC was a Kanter-controlled investment company and Zion was a THC subsidiary. See supra note 24.
. The Tax Court opinion and the Commissioner’s brief both indicate that this transfer occurred on January 8, 1983. It is of no significance to the disposition of the case, but the bank transfer record (Ex. 9203PK) and the THC adjusting journal entry (Ex. 146, entry 32) both indicate that the transfer took place on January 4, 1983.
. Section 357(c) provides in relevant part:
(c) Liabilities in excess of basis.—
(1) In general. In the case of an exchange—
(A) to which section 351 applies ...
if the sum of the amount of the liabilities assumed exceeds the total of the adjusted basis of the property transferred pursuant to such exchange, then such excess shall be considered as a gain from the sale or exchange of a capital asset or of property which is not a capital asset, as the case may be.
26 U.S.C. § 357(c).
. As noted, Cashmere’s assets included $498,500 in cash plus the partnership interests. Therefore, the $1,647,500 purchase price of Cashmere included a purchase price of $1,149,000 for the real estate partnership interests.
. Section 357(c)(2)(A) gives priority to § 357(b)(1) when both § 357(c) and § 357(b)(1) apply. Therefore, the finding under § 357(c) is only relevant as the alternative to the previous finding under § 357(b)(1).
. Section § 453(c) states:
For purposes of this section, the term "installment method” means a method of payment under which the income recognized for any taxable year from a disposition is that proportion of the payments received in that year which the gross profit (realized or to be realized when payment is completed) bears to the total contract price.
26 U.S.C. § 453(c).
. We note with some trepidation that there was no effort by the Tax Court to identify the precise actuarial interests of the beneficiaries of BRT nor how precisely those beneficiaries’ identities matched the beneficiaries of the grantor trusts. This information would be relevant for determining the exact percentage of Waco stock owned by the BRT beneficiaries (who were also grantor trust beneficiaries), which would then be imputed to the grantor trusts. Because Kanter did not make this argument on this issue, however, we will not disturb the Tax Court’s determination. United States v. Jones, 34 F.3d 495, 499 (7th Cir.1994) (finding argument not made before this court in opening brief is waived).
. There does not appear to be any obstacle in the statute, legislative history, or regulations to the attribution of a grantor trust’s stock ownership to the beneficiaries of a trust as well as to the substantial owner of a trust under §§ 671 et seq. See The Attribution Rules, 554-2d Tax Mgmt. Portfolio at A-11 (1996) ("Apparently, attribution from the [grantor] trust to the beneficiaries and from the beneficiaries to the trust would still occur, even if the grantor or another is deemed to be the 'owner,' although the statute and legislative history are ambiguous on this point and the regulations are silent.”). Nor does any court appear to have ruled on the issue. Our research unearthed only one commentator who has suggested that attribution to a grant- or precludes attribution to the beneficiaries. See Shop Talk, Is Stock Attributed to Beneficiaries of Grantor Trusts?, 65 J. TAX’N 207 (Burton W. Kanter & Sheldon I. Banoff ed., 1986) ("A common sense interpretation of Section 318(a)(2)(B)(ii) should be that its specific rule regarding attribution from grantor trusts should preempt the general rule of trust attribution of Section 318(a)(2)(B)(i).”). The financial interest in this matter of one of the editors of the article may diminish the persuasive value of the proposed answer.
