- 10 - to section 7491(a), the burden of proof on factual issues that affect the taxpayer’s tax liability may be shifted to the Commissioner where the “taxpayer introduces credible evidence with respect to * * * such issue.” The burden will shift only if the taxpayer has, inter alia, complied with substantiation requirements pursuant to the Internal Revenue Code and “cooperated with reasonable requests by the Secretary for witnesses, information, documents, meetings, and interviews”. Sec. 7491(a)(2). In the instant case, petitioners did not argue that the burden should shift, and they failed to comply with the substantiation requirements. Accordingly, the burden of proof remains on petitioners. II. Deductions A. General Rules Deductions are a matter of legislative grace, and the taxpayer bears the burden of proving that he is entitled to any claimed deductions. INDOPCO, Inc. v. Commissioner, 503 U.S. 79, 84 (1992); New Colonial Ice Co. v. Helvering, 292 U.S. 435, 440 (1934). Taxpayers must maintain records relating to their income and expenses and must prove their entitlement to all claimed deductions, credits, and expenses in controversy. See sec. 6001; Rule 142(a); INDOPCO, Inc. v. Commissioner, supra at 84; Welch v. Helvering, supra at 115.Page: Previous 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 NextLast modified: March 27, 2008
