This appeal involves a claim for refund of $44,553.35 in federal income taxes paid by Elot H. Raffety Farms, Inc., a Missouri corporation, in the taxable years ending March 31 of 1964, 1967, 1968, 1969, and 1970. The United States District Court for the Eastern District of Missouri granted recovery. We reverse.
From the record, it appears that in early 1965 taxpayer, through its president and principal stockholder (Elot Raffety), agreed orally with L. D. Joslyn, a Missouri attorney, and the Rolwing-Moxley Company (the “Missouri partners”) to conduct cotton farming operations in the Republic of Mexico. They agreed that Raffety Farms would own a one-half interest in the enterprise and each of the other partners would own a one-quarter interest. Elot Raffety himself would act as the manager.
When it was discovered that Mexican law effectively prohibits farm operations by foreign nationals, attorney Joslyn employed Mexican counsel and instructed him to take whatever steps were necessary to enable them to farm there legally. Shortly thereafter, the Mexican lawyer organized El Sombrero Sociedad de Responsibilidad Limitada to conduct the farming business. Under its charter, El Sombrero was authorized to lease land to process cotton, and in general to do all lawful acts related to an agricultural business. The business capital was fixed at 3,000,000 pesos to be provided by three Mexican organizers; the number of members of the company was limited to twenty-five; and the business was to be conducted by an administrator, Luis Vargas Nunez. No conveyance or assignment of any interest in El Sombrero was ever made to the taxpayer, nor did El Sombrero in fact ever issue any stock. The three Mexicans whose names appeared in El Sombrero’s articles of organization never contributed any capital to .the business, nor did they perform any services for which they were paid by the taxpayer.
During the taxable years in question, taxpayer and the Missouri partners put up substantial sums of money towards the cost of operations of El Sombrero. Taxpayer advanced $200,000 in 1966 and an additional $22,000 in 1967; Joslyn and Rolwing-Moxley matched those amounts. In exchange, however, no notes were issued by El Sombrero; there was no provision for interest; and no interest was paid. No security was established for the money so advanced. There was no fixed maturity date for repayment; indeed, no money so advanced was even required to be repaid, and none was repaid.
In the summer of 1965, Luis Vargas Nunez, acting in his capacity as administrator for El Sombrero, executed some 30 leases for farming land on the east coast of Mexico near Tampico, totalling thousands of acres. A few months later, in April of 1966, Raffety moved to Mexico and commenced operations. In the name of El Sombrero, he opened and maintained bank accounts, contracted for goods and services, and borrowed almost half a million dollars from Cook & Company, signing the promissory notes om El *1237Sombrero’s behalf. From the first, however, adverse fortune plagued the business.
Approximately 7,300 acres of cotton had been planted and had come up when Hurricane Inez struck in the first week of October, 1966, leaving less than 600 bales of cotton harvestable. The next year, after an initial dry season, crops were just coming up when Hurricane Beulah hit, drowning the cotton and making the acreage impossible to cultivate. Turning to safflower as a wintertime stopgap, Raffety planted that crop in November and December of 1967, but by the time it was harvested in the Spring of 1968, financial difficulties had caught up to El Sombrero, forcing the company to cease operations. Since payments on the Cook & Company loans were overdue, that creditor sued in Mexican court and obtained a judgment for $95,052.78 against El Sombrero as an organizational entity.1 At the trial both Raffety and Señor Nunez appeared on behalf of El Sombrero.
Taxpayer never recovered its original advances to El Sombrero. Subsequently a complaint was filed in federal district court seeking a refund on income taxes paid between 1964 and 1970, and contending, alternatively, that the losses were deductible from income as:
(1) operating losses under 26 U.S.C. § 165(a);
(2) bad debt losses under 26 U.S.C. § 166(a)(1); or
(3) ordinary business expenses under 26 U.S.C. § 162(a).
In response the Government argued that the advances were simply contributions to the capital of an “association” taxable as a corporation and must be characterized as capital losses under 26 U.S.C. § 165(f).
In a memorandum decision, D.C.Mo., 369 F.Supp. 653, filed December 27, 1973, the district court found as follows:
Although this S. de R. L. is an association taxable as a corporation under the Code, the Court is of the opinion that it must be disregarded for tax purposes as it was but a passive entity.
The El Sombrero S. de R. L. was not organized for the purpose of avoiding taxes. Rather, it was organized upon the advice of Mexican legal counsel to allow the Missouri partners to farm in Mexico without being in violation of Mexican law. However, the S. de R. L. performed no substantial business function.
The court drew attention to the taxpayer’s regular business of farming in Missouri and concluded that the Mexican cotton-growing operation was no more than an extension of its existing business. The lost advances were therefore ordinary and necessary expenses, deductible under 26 U.S.C. § 162(a). We cannot agree with the trial court.
The district court correctly classified El Sombrero as a corporate entity, i. e., an “association” under the Code. The relevant rule is that:
An unincorporated organization shall not be classified as an association unless such organization has more corporate characteristics than noncorporate characteristics. [Treas.Reg. § 301.-7701-2(a)(3).]
The key factors to be considered are continuity of life, centralization of management, liability for corporate debts limited to corporate property, and free transferability of interests. Treas.Reg. § 301.7701 — 2(a).
Under Mexican law, it is clear that El Sombrero did have more corporate characteristics than non-corporate ones. Its liability was limited to its capital; its management was centrally controlled in the hands of an administrator; its life was continuous for at least 20 years, without limitation by death or separation of any of the members; it was required *1238to have an annual meeting and an annual accounting; the fiscal year was the calendar one; the liquidation of the corporation was to be handled by the manager or other person designated by the members; and there could be only 25 members. Although the members of El Sombrero did not formally enjoy the right of free transferability of interests, the organization must be treated as a corporate entity since it possessed the remaining characteristics. Nevertheless, as we noted above, the district court chose to disregard El Sombrero’s legal form and to focus on its “passive” nature. We think this puts the shoe on the wrong foot.
Since any income tax deduction is a matter of legislative grace, the claimant bears the burden of proving that he comes within its provisions. Interstate Transit Lines v. Commissioner, 319 U.S. 590, 593, 63 S.Ct. 1279, 87 L.Ed. 1607 (1943). In the business area, once a corporate entity has been identified, it may not be disregarded in respect to taxation if it was intended to “have some real substantial business function, or if it actually engages in business.” Jackson v. Commissioner, 233 F.2d 289, 290 (2d Cir. 1956). Here, El Sombrero did have an intended purpose and did engage in business. Indeed, it was the sine qua non of the Missouri group’s being permitted to farm in Mexico. Without it, not one acre of land could have been leased, not one dollar borrowed, not one field plowed, nor one seed planted. It was the business entity through which the entire enterprise functioned and in whose name its operations were performed. As the Supreme Court has stated in Moline Properties v. Commissioner, 319 U.S. 436, 438, 63 S.Ct. 1132, 1134, 87 L.Ed. 1499 (1943):
The doctrine of corporate entity fills a useful purpose in business life. Whether the purpose be to gain an advantage under the law of the state of incorporation or to avoid or to comply with the demands of creditors or to serve the creator’s personal or undisclosed convenience, so long as that purpose is the equivalent of business activity or is followed by the carrying on of business by the corporation, the corporation remains a separate taxable entity. [Emphasis added]
Cf. Omaha Public Power District v. O’Malley, 216 F.2d 764 (8th Cir. 1954).
In its brief, taxpayer argues that El Sombrero was “a fictional farce” that conducted no business operations itself. In particular, appellant stresses that Nunez, the so-called “administrator” of El Sombrero, had absolutely nothing to do with the operation of the business in Mexico. Taxpayer states:
Luis Vargas Nunez did not handle the business of El Sombrero. There was no accounting or administration made annually and when the business was liquidated in 1968, it was not carried out by Mr. Nunez. Nunez had nothing to do with the management of the farming business and the three Missouri partners had equal voice and control in the management of the partnership affairs.
The bald facts of the record are to the contrary.
El Sombrero obtained and signed, through its administrator Nunez, leases on the 7,300 acres of land on which it conducted farming operations in Mexico; it received and paid out the funds (including those paid in by Raffety Farms and now claimed as deductions) used in the Mexican operation; it contracted for goods and services, bought machinery, and created a line of credit; it negotiated loans; and, finally, when the end came, it suffered a suit by Cook & Company in the Mexican courts in which administrator Nunez appeared for the company. While it is true that Elot Raffety personally supervised the actual farming, the entire operation was conducted in El Sombrero’s name.2
*1239The record disproves that El Sombrero was, as taxpayer insists, “a sham and a dummy organization” created for the purpose of evading Mexican law. On the contrary, it emerges as a viable, commercially active company operating on a million-dollar scale in Mexico which afforded to its true owners complete protection from personal liability. Taxpayer may not escape liability in a foreign nation’s courts under one theory and then seek an advantage in this nation’s courts by contending its opposite. That El Sombrero may not have been operated in complete accord with Mexican law or its charter is, at this late date, an irrelevancy.3
Alternatively, taxpayer urges that El Sombrero be viewed as, at most, an agent or nominee for the Missouri partners and that the losses are therefore attributable to the latter. We must reject this contention, for nothing in the record suggests that El Sombrero acted in the name of Raffety Farms, Joslyn, or Rolwing-Moxley in the conduct of its affairs with third parties. See Harrison Property Management Co., Inc. v. United States, 475 F.2d 623, 201 Ct.Cl. 77 (1973).
Since the entity status of El Sombrero must be recognized, appellant’s three claimed bases for deductions must accordingly be rejected. Raffety Farms paid the $222,000 at issue into the Mexican venture as a start-up expense and received a pure equity interest in El Sombrero proportionate to that contribution; no intent to repay or other indicia of a loan existed. Unquestionably, this capital investment may not be characterized as a “debt” under the bad debt loss provision of 26 U.S.C. § 166(a)(1). Further, we cannot accept the claim that El Sombrero was a mere extension of taxpayer’s on-going farming activities in Missouri; it had no relationship with Raffety Farms’ other agricultural operations. El Sombrero was a separate and distinct enterprise operating in a foreign country and in conjunction with other parties. Its expenditures for labor, equipment, and leases cannot be characterized as taxpayer’s ordinary and necessary business expenses under 26 U.S.C. § 162(a). Hagan v. United States, 221 F.Supp. 248 (W.D.Ark.1963), and Lutz v. Commissioner, 282 F.2d 614 (5th Cir. 1960), on which appellant relies, are therefore inapposite. The losses sustained by the Mexican operation are El Sombrero’s alone, and, since taxpayer’s interest in that company was a capital asset, may be deducted under 26 U.S.C. § 165 only to the extent allowed in §§ 1211-1212. See 26 U.S.C. § 165(f).
The judgment is reversed.
. Having guaranteed payment of the notes for El Sombrero, Raffety was made a party to the litigation, and his private airplane was temporarily seized when Cook & Company levied on the company’s assets. It was apparently returned subsequently.
. The documents in this case make unmistakably clear that the parties perceived El Sombrero as a separate entity. For example, on May 17, 1967, attorney Joslyn (one of the *1239Missouri partners) wrote to one John Baldridge of Tampico, Mexico, regarding acquisition of land by the company, saying:
Sombrero has continued to prepare this farmland since its first oral agreement was reached in Tampico and has expended much money, time and effort thereon.
Moreover, the contract for establishing credit with Cook & Company, signed by Luis Vargas Nunez, as administrator of El Sombrero, and Elot Raffety, as guarantor, specifically designated El Sombrero as “The Grower”, not Mr. Raffety. The tenth paragraph of this document obligated the grower “to continue delivering to the company [Cook] . . . the crops and fruits”. And the eleventh paragraph obligated the grower “to sell to the company . . . the entire cotton crop . Furthermore, by letter to Cook & Company on September 17, 1968, Elot Raffety himself, representing El Sombrero, requested “a full accounting of the relationship between El Sombrero and your Company” and notes that Cook has in its possession “a good bit of our machinery and undoubtedly have sold some of it but we have had no word as to either the detailed account or credits on it . ” Significantly, the letter closes with the observation that “Mr. Joslyn wrote you asking for an accounting and he says he has heard nothing.” The letter is signed “Sombrero S. de R. L.” on the typewriter and below it appears the name of “Elot Raffety”.
. So too, it is unavailing to appellant that the Missouri partners believed that they were only forming a limited partnership. The status of a taxpayer is determined not by what the taxpayer thought, but by the terms of the instrument which created it. Wholesalers Adjustment Co. v. Commissioner, 88 F.2d 156 (8th Cir. 1937).
