- 5 - U.S. 435 (1934). Taxpayers are required to maintain records that are sufficient to enable the Commissioner to determine their correct tax liability. See sec. 6001; Meneguzzo v. Commissioner, 43 T.C. 824, 831-832 (1965); sec. 1.6001-1(a), Income Tax Regs. Moreover, a taxpayer who claims a deduction bears the burden of substantiating the amount and purpose of the item claimed. Hradesky v. Commissioner, 65 T.C. 87, 90 (1975), affd. per curiam 540 F.2d 821 (5th Cir. 1976); sec. 1.6001-1(a), Income Tax Regs. Under certain circumstances, however, if a taxpayer establishes the entitlement to a deduction but does not establish the amount of the deduction, we may estimate the amount allowable, Cohan v. Commissioner, 39 F.2d 540, 543-544 (2d Cir. 1930), if the taxpayer provides some rational basis upon which an estimate may be made, Vanicek v. Commissioner, 85 T.C. 731, 743 (1985). In estimating the amount allowable, we bear heavily upon the taxpayers, whose inexactitude is of their own making. Cohan v. Commissioner, supra at 543-544. Respondent contends that petitioners are not entitled to any deductions beyond the amounts allowed in the notice of deficiency and in the stipulations. Petitioners, however, contend that they are entitled to all of the deductions that they claimed on their return. As all of their records were destroyed by fire, petitioners seek to establish their entitlement to the disallowed deductions through their testimony only.Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Next
