delivered the opinion of the Court.
This case presents the issue whether, and to what extent, the Fifth Amendment privilege against compelled self-incrimination applies to the business records of a sole proprietorship.
I
Respondent is the owner of several sole proprietorships. In late 1980, a grand jury, during the course of an investigation of corruption in the awarding of county and municipal contracts, served five subpoenas on respondent. The first two demanded the production of the telephone records of several of respondent’s companies and all records pertaining to four bank accounts of respondent and his companies. The subpoenas were limited to the period between January 1, 1977, and the dates of the subpoenas. The third subpoena demanded the production of a list of virtually all the business records of one of respondent’s companies for the period be*607tween January 1, 1976, and the date of the subpoena.1 The fourth subpoena sought production of a similar list of business records belonging to another company.2 The final subpoena demanded production of all bank statements and cancelled checks of two of respondent’s companies that had accounts at a bank in the Grand Cayman Islands.

Respondent filed a motion in Federal District Court seeking to quash the subpoenas. The District Court for the District of New Jersey granted his motion except with respect to those documents and records required by law to be kept or disclosed to a public agency.3 In reaching its decision, the *608District Court noted that the Government had conceded that the materials sought in the subpoena were or might be incriminating. The court stated that, therefore, “the relevant inquiry is . . . whether the act of producing the documents has communicative aspects which warrant Fifth Amendment protection.” In re Grand Jury Empanelled March 19, 1980, 541 F. Supp. 1, 3 (1981) (emphasis in original). The court found that the act of production would compel respondent to “admit that the records exist, that they are in his possession, and that they are authentic.” Ibid. While not ruling out the possibility that the Government could devise a way to ensure that the act of turning over the documents would not incriminate respondent, the court held that the Government had not made such a showing.
The Court of Appeals for the Third Circuit affirmed. In re Grand Jury Empanelled March 19, 1980, 680 F. 2d 327 (1982). It first addressed the question whether the Fifth Amendment ever applies to the records of a sole proprietorship. After noting that an individual may not assert the Fifth Amendment privilege on behalf of a corporation, partnership, or other collective entity under the holding of Bellis v. United States, 417 U. S. 85 (1974),4 the Court of Appeals reasoned that the owner of a sole proprietorship acts in a personal rather than a representative capacity. As a result, the court held that respondent’s claim of the privilege was not foreclosed by the reasoning of Bellis. 680 F. 2d, at 331.
The Court of Appeals next considered whether the documents at issue in this case are privileged. The court noted that this Court held in Fisher v. United States, 425 U. S. 391 (1976), that the contents of business records ordinarily are *609not privileged because they are created voluntarily and without compulsion. The Court of Appeals nevertheless found that respondent’s business records were privileged under either of two analyses. First, the court reasoned that, notwithstanding the holdings in Beilis and Fisher, the business records of a sole proprietorship are no different from the individual owner’s personal records. Noting that Third Circuit cases had held that private papers, although created voluntarily, are protected by the Fifth Amendment,5 the court accorded the same protection to respondent’s business papers.6 Second, it held that respondent’s act of producing the subpoenaed records would have “communicative aspects of its own.” 680 F. 2d, at 335. The turning over of the subpoenaed documents to the grand jury would admit their existence and authenticity. Accordingly, respondent was entitled to assert his Fifth Amendment privilege rather than produce the subpoenaed documents.
The Government contended that the court should enforce the subpoenas because of the Government’s offer not to use respondent’s act of production against respondent in any *610way. The Court of Appeals noted that no formal request for use immunity under 18 U. S. C. §§6002 and 6003 had been made. In light of this failure, the court held that the District Court did not err in rejecting the Government’s attempt to compel delivery of the subpoenaed records.
We granted certiorari to resolve the apparent conflict between the Court of Appeals’ holding and the reasoning underlying this Court’s holding in Fisher. 461 U. S. 913 (1983). We now affirm in part, reverse in part, and remand for further proceedings.
Ill
A
The Court in Fisher expressly declined to reach the question whether the Fifth Amendment privilege protects the contents of an individual’s tax records in his possession.7 The rationale underlying our holding in that case is, however, persuasive here. As we noted in Fisher, the Fifth Amendment protects the person asserting the privilege only from compelled, self-incrimination. 425 U. S., at 396. Where the preparation of business records is voluntary, no compulsion is present.8 A subpoena that demands production of docu*611ments “does not compel oral testimony; nor would it ordinarily compel the taxpayer to restate, repeat, or affirm the truth of the contents of the documents sought.” Id., at 409. Applying this reasoning in Fisher, we stated:
“[T]he Fifth Amendment would not be violated by the fact alone that the papers on their face might incriminate the taxpayer, for the privilege protects a person only against being incriminated by his own compelled testimonial communications. Schmerber v. California, [384 U. S. 757 (1966)]; United States v. Wade, [388 U. S. 218 (1967)]; and Gilbert v. California, [388 U. S. 263 (1967)]. The accountant’s workpapers are not the taxpayer’s. They were not prepared by the taxpayer, and they contain no testimonial declarations by him. Furthermore, as far as this record demonstrates, the preparation of all of the papers sought in these cases was wholly voluntary, and they cannot be said to contain compelled testimonial evidence, either of the taxpayers or of anyone else. The taxpayer cannot avoid compliance with the subpoena merely by asserting that the item of evidence which he is required to produce contains incriminating writing, whether his own or that of someone else.” Id., at 409-410.
This reasoning applies with equal force here. Respondent does not contend that he prepared the documents involun*612tarily9 or that the subpoena would force him to restate, repeat, or affirm the truth of their contents. The fact that the records are in respondent’s possession is irrelevant to the determination of whether the creation of the records was compelled. We therefore hold that the contents of those records are not privileged.10
B
Although the contents of a document may not be privileged, the act of producing the document may be. Id., at 410. A government subpoena compels the holder of the document to perform an act that may have testimonial aspects and an incriminating effect. As we noted in Fisher:
*613“Compliance with the subpoena tacitly concedes the existence of the papers demanded and their possession or control by the taxpayer. It also would indicate the taxpayer’s belief that the papers are those described in the subpoena. Curcio v. United States, 354 U. S. 118, 125 (1957). The elements of compulsion are clearly present, but the more difficult issues are whether the tacit aver-ments of the taxpayer are both ‘testimonial’ and ‘incriminating’ for purposes of applying the Fifth Amendment. These questions perhaps do not lend themselves to categorical answers; their resolution may instead depend on the facts and circumstances of particular cases or classes thereof.” Id., at 410.
In Fisher, the Court explored the effect that the act of production would have on the taxpayer and determined that the act of production would have only minimal testimonial value and would not operate to incriminate the taxpayer. Unlike the Court in Fisher, we have the explicit finding of the District Court that the act of producing the documents would involve testimonial self-incrimination.11 The Court of Appeals agreed.12 The District Court’s finding essentially rests on its *614determination of factual issues. See United States v. Nixon, 418 U. S. 683, 702 (1974). Therefore, we will not overturn that finding unless it has no support in the record. Ibid. Traditionally, we also have been reluctant to disturb findings of fact in which two courts below have concurred. Rogers v. Lodge, 458 U. S. 613, 623 (1982). We therefore decline to overturn the finding of the District Court in this regard, where, as here, it has been affirmed by the Court of Appeals.13
IV
The Government, as it concedes, could have compelled respondent to produce the documents listed in the subpoena. *615Title 18 U. S. C. §§ 6002 and 6003 provide for the granting of use immunity with respect to the potentially incriminating evidence.14 The Court upheld the constitutionality of the use immunity statute in Kastigar v. United States, 406 U. S. 441 (1972).
*616The Government did state several times before the District Court that it would not use respondent’s act of production against him in any way. But counsel for the Government never made a statutory request to the District Court to grant respondent use immunity.15 We are urged to adopt a doctrine of constructive use immunity. Under this doctrine, the courts would impose a requirement on the Government not to use the incriminatory aspects of the act of production against the person claiming the privilege even though the statutory procedures have not been followed.
We decline to extend the jurisdiction of courts to include prospective grants of use immunity in the absence of the formal request that the statute requires.16 As we stated in Pillsbury Co. v. Conboy, 459 U. S. 248 (1983), in passing the use immunity statute, “Congress gave certain officials in the Department of Justice exclusive authority to grant immunities.” Id., at 253-254 (footnotes omitted). “Congress foresaw the courts as playing only a minor role in the immunizing process . . . .” Id., at 254, n. 11. The decision to seek use immunity necessarily involves a balancing of the Government’s interest in obtaining information against the risk that immunity will frustrate the Government’s attempts to prosecute the subject of the investigation. See United States v. Mandujano, 425 U. S. 564, 575 (1976) (plurality opinion). Congress expressly left this decision exclusively to the Jus*617tice Department. If, on remand, the appropriate official concludes that it is desirable to compel respondent to produce his business records, the statutory procedure for requesting use immunity will be available.17
V
We conclude that the Court of Appeals erred in holding that the contents of the subpoenaed documents were privileged under the Fifth Amendment. The act of producing the documents at issue in this case is privileged and cannot be compelled without a statutory grant of use immunity pursuant to 18 U. S. C. §§6002 and 6003. The judgment of the Court of Appeals is, therefore, affirmed in part and reversed in part,18 and the case is remanded to the District Court for further proceedings consistent with this opinion.
It is so ordered.
The categories of records sought by the third subpoena were: (1) general ledgers; (2) general journals; (3) cash disbursement journals; (4) petty cash books and vouchers; (5) purchase journals; (6) vouchers; (7) paid bills; (8) invoices; (9) cash receipts journal; (10) billings; (11) bank statements; (12) canceled checks and check stubs; (13) payroll records; (14) contracts and copies of contracts, including all retainer agreements; (15) financial statements; (16) bank deposit tickets; (17) retained copies of partnership income tax returns; (18) retained copies of payroll tax returns; (19) accounts payable ledger; (20) accounts receivable ledger; (21) telephone company statement of calls and telegrams, and all telephone toll slips; (22) records of all escrow, trust, or fiduciary accounts maintained on behalf of clients; (23) safe deposit box records; (24) records of all purchases and sales of all stocks and bonds; (25) names and home addresses of all partners, associates, and employees; (26) W-2 forms of each partner, associate, and employee; (27) workpapers; and (28) copies of tax returns.
The only documents requested in the fourth subpoena that were not requested in the third were the company’s stock transfer book, any corporate minutes, the corporate charter, all correspondence and memoranda, and all bids, bid bonds, and contracts. The request for “corporate” minutes and the “corporate” charter is puzzling because the company named in the subpoena was an unincorporated sole proprietorship.
The District Court mentioned tax returns and W-2 statements as examples of documents falling within this category. Respondent has not challenged this aspect of the District Court’s opinion. We therefore understand that this ease concerns only business documents and records not required by law to be kept or disclosed to a public agency. We also note *608that our opinion addresses only the Fifth Amendment implications of the subpoenas. The subpoenas were drawn in the broadest possible terms. It may be that the breadth of the subpoenas is subject to attack on other grounds that are not before us.
Bellis defined a “collective entity” as “an organization which is recognized as an independent entity apart from its individual members.” 417 U. S., at 92.
See In re Grand Jury Proceedings (Johanson), 632 F. 2d 1033 (1980); ICC v. Gould, 629 F. 2d 847 (1980), cert. denied, 449 U. S. 1077 (1981).
Justice Stevens apparently reads the Court of Appeals’ decision as merely affirming the District Court’s finding that the act of producing the subpoenaed records was privileged. In support of this hypothesis, he quotes extensively from that portion of the Court of Appeals’ opinion that addresses the act-of-production issue. The quoted passage, however, begins after the court has discussed whether the records themselves are privileged. After noting that Fisher could be read to deprive the contents of a sole proprietorship’s records of Fifth Amendment protection, the court noted that other Third Circuit cases — principally ICC v. Gould, supra, had refused to adopt that interpretation. The court stated: “Gould, then, stands for the proposition that an individual’s business papers, as well as his personal records, cannot be subpoenaed by a grand jury.” 680 F. 2d, at 334 (footnote omitted). The court went on to hold, in the alternative, that the act of production is privileged as well. We note in passing that both parties share our interpretation of the Court of Appeals’ opinion. Brief for United States 5; Brief for Respondent 3-4.
In Fisher, the Court stated: “Whether the Fifth Amendment would shield the taxpayer from producing his own tax records in his possession is a question not involved here; for the papers demanded here are not his ‘private papers,’. . .” 425 U. S., at 414. We note that in some respects the documents sought in Fisher were more “personal” than those at issue here. The Fisher documents were accountant’s workpapers in the possession of the taxpayers’ lawyers. The workpapers related to the taxpayers’ individual personal returns. To that extent, the documents were personal, even though in the possession of a third party. In contrast, each of the documents sought here pertained to respondent’s businesses.
Respondent’s principal argument is that the Fifth Amendment should be read as creating a “zone of privacy which protects an individual and his personal records from compelled production.” Brief for Respondent 15. This argument derives from language in Boyd v. United States, 116 U. S. 616, 630 (1886). This Court addressed substantially the same argument in Fisher:
*611“Within the limits imposed by the language of the Fifth Amendment, which we necessarily observe, the privilege truly serves privacy interests; but the Court has never on any ground, personal privacy included, applied the Fifth Amendment to prevent the otherwise proper acquisition or use of evidence which, in the Court’s view, did not involve compelled testimonial self-incrimination of some sort.” 425 U. S., at 399.
In Andresen v. Maryland, 427 U. S. 463 (1976), the petitioner also relied on Boyd. In rejecting his argument, we observed that “the continued validity of the broad statements contained in some of the Court’s earlier cases [has] been discredited by later opinions.” 427 U. S., at 472. See also United States v. Nobles, 422 U. S. 225, 233, n. 7 (1975).
The Court of Appeals recognized the absence of compulsion in the compilation of the records sought in this case and those sought in Fisher. “To be sure, the documents requested here, like those sought in Fisher, were voluntarily prepared, and therefore ‘cannot be said to contain compelled testimonial evidence’ in and of themselves.” 680 F. 2d, at 334. The Court of Appeals nevertheless gave our holding in Fisher an unduly restrictive reading and found it not to control the outcome in this case.
Accord, In re Grand Jury Proceedings, 626 F. 2d 1051, 1055 (CA1 1980) (“The line of cases culminating in Fisher have stripped the content of business records of any Fifth Amendment protection”). While not directly on point, Andresen v. Maryland, supra, is consistent with our holding. In Andresen, investigators from a bicounty fraud unit obtained warrants to search the petitioner’s office. During the search, the investigators seized several incriminating business records relating to the petitioner’s practice as a sole practitioner of real estate law. The petitioner sought suppression of the documents on Fourth and Fifth Amendment grounds. The petitioner based his Fifth Amendment argument on “dicta in a number of cases which imply, or state, that the search for and seizure of a person’s private papers violate the privilege against self-incrimination.” Id., at 471. The Court dismissed this argument and found the documents not to be privileged because the petitioner “had voluntarily committed to writing” any incriminating statements contained therein. Id., at 473. Although Andresen involved a search warrant rather than a subpoena, the underlying principle is the same in this context. If the party asserting the Fifth Amendment privilege has voluntarily compiled the document, no compulsion is present and the contents of the document are not privileged.
The District Court stated:
“With few exceptions, enforcement of the subpoenas would compel [respondent] to admit that the records exist, that they are in his possession, and that they are authentic. These communications, if made under compulsion of a court decree, would violate [respondent’s] Fifth Amendment rights. . . . The government argues that the existence, possession and authenticity of the documents can be proved without [respondent’s] testimonial communication, but it cannot satisfy this court as to how that representation can be implemented to protect the witness in subsequent proceedings.” 541 F. Supp., at 3.
The Court of Appeals stated:
“In the matter sub judice, however, we find nothing in the record that would indicate that the United States knows, as a certainty, that each of the myriad documents demanded by the five subpoenas in fact is in the ap-pellee’s possession or subject to his control. The most plausible inference to be drawn from the broad-sweeping subpoenas is that the Government, unable to prove that the subpoenaed documents exist — or that the appellee *614even is somehow connected to the business entities under investigation — is attempting to compensate for its lack of knowledge by requiring the appel-lee to become, in effect, the primary informant against himself.” 680 F. 2d, at 335 (footnote omitted).
The Government concedes that the act of producing the subpoenaed documents might have had some testimonial aspects, but it argues that any incrimination would be so trivial that the Fifth Amendment is not implicated. The Government finds support for this argument in Marchetti v. United States, 390 U. S. 39 (1968). In Marchetti, the Court stated that a party who wishes to claim the Fifth Amendment privilege must be “confronted by substantial and ‘real,’ and not merely trifling or imaginary, hazards of incrimination.” Id., at 53; see United States v. Apfelbaum, 445 U. S. 115, 128 (1980). On the basis of the findings made in this case we think it clear that the risk of incrimination was “substantial and real” and not “trifling or imaginary.” Respondent did not concede in the District Court that the records listed in the subpoena actually existed or were in his possession. Respondent argued that by producing the records, he would tacitly admit their existence and his possession. Respondent also pointed out that if the Government obtained the documents from another source, it would have to authenticate them before they would be admissible at trial. See Fed. Rule Evid. 901. By producing the documents, respondent would relieve the Government of the need for authentication. These allegations were sufficient to establish a valid claim of the privilege against self-incrimination. This is not to say that the Government was foreclosed from rebutting respondent’s claim by producing evidence that possession, existence, and authentication were a “foregone conclusion.” Fisher, 425 U. S., at 411. In this case, however, the Government failed to make such a showing.
Section 6002 provides:
“Whenever a witness refuses, on the basis of his privilege against self-incrimination, to testify or provide other information in a proceeding before or ancillary to—
“(1) a court or grand jury of the United States,
“(2) an agency of the United States, or
“(3) either House of Congress, a joint committee of the two Houses, or a committee or a subcommittee of either House,
“and the person presiding over the proceeding communicates to the witness an order issued under this part, the witness may not refuse to comply with the order on the basis of his privilege against self-incrimination; but no testimony or other information compelled under the order (or any information directly or indirectly derived from such testimony or other information) may be used against the witness in any criminal case, except a prosecution for perjury, giving a false statement, or otherwise failing to comply with the order.”
Section 6003 provides:
“(a) In the case of any individual who has been or may be called to testify or provide other information at any proceeding before or ancillary to a court of the United States or a grand jury of the United States, the United States district court for the judicial district in which the proceeding is or may be held shall issue, in accordance with subsection (b) of this section, upon the request of the United States attorney for such district, an order requiring such individual to give testimony or provide other information which he refuses to give or provide on the basis of his privilege against self-incrimination, such order to become effective as provided in section 6002 of this part.
“(b) A United States attorney may, with the approval of the Attorney General, the Deputy Attorney General, or any designated Assistant Attorney General, request an order under subsection (a) of this section when in his judgment—
“(1) the testimony or other information from such individual may be necessary to the public interest; and
“(2) such individual has refused or is likely to refuse to testify or provide other information on the basis of his privilege against self-incrimination.”
Despite repeated questioning at oral argument, counsel for the Government gave no plausible explanation for the failure to request official use immunity rather than promising that the act of producing the documents would not be used against respondent.
Of course, courts generally suppress compelled, incriminating testimony that results from a violation of a witness’ Fifth Amendment rights. See United States v. Mandujano, 425 U. S. 564, 576 (1976); United States v. Blue, 384 U. S. 251, 255 (1966). The difference between that situation and the Government’s theory of constructive use immunity is that in the latter it is the grant of judicially enforceable use immunity that compels the witness to testify. In the former situation, exclusion of the witness’ testimony is used to deter the Government from future violations of witnesses’ Fifth Amendment rights.
Respondent argues that any grant of use immunity must cover the contents of the documents as well as the act of production. We find this contention unfounded. To satisfy the requirements of the Fifth Amendment, a grant of immunity need be only as broad as the privilege against self-incrimination. Murphy v. Waterfront Comm’n, 378 U. S. 52, 107 (1964) (White, J., concurring); see Pillsbury Co. v. Conboy, 459 U. S., at 253, n. 8; United States v. Calandra, 414 U. S. 338, 346 (1974). As discussed above, the privilege in this case extends only to the act of production. Therefore, any grant of use immunity need only protect respondent from the self-incrimination that might accompany the act of producing his business records.
Justice Stevens states that we should affirm the Court of Appeals decision as a whole because our reasoning is entirely consistent with that of the courts below. See post, at 623. As we stated above, see n. 6, supra, we read the opinion of the Court of Appeals as holding that the contents of the subpoenaed records were privileged. It is that aspect of the court’s opinion that we reverse today. Were we to adopt Justice Stevens’ suggestion, respondent could argue on remand that any grant of use immunity must cover the contents of the records because the records themselves are privileged under the holding of the Court of Appeals. To avoid that result, we must reverse the decision below insofar as it held that the contents of the subpoenaed records are privileged.
