- 16 - OPINION Unreported Flowthrough Income As a general rule, a taxpayer challenging the Commissioner’s determinations in a notice of deficiency bears the burden of proof. Rule 142(a). That burden may shift to the Commissioner if the taxpayer introduces credible evidence with respect to any factual issue relevant to ascertaining the taxpayer’s tax liability. Sec. 7491(a)(1). However, section 7491(a)(1) applies with respect to an issue only if the taxpayer has complied with the requirements under the Code to substantiate any item, has maintained all records required by the Code, and has cooperated with reasonable requests by the Commissioner for witnesses, information, documents, meetings, and interviews. Sec. 7491(a)(2)(A) and (B). Petitioners have not satisfied the conditions for shifting the burden of proof to respondent. In any event, the evidence establishes overstatement of cost of goods sold resulting in understated income and understated tax liability. In calculating gross income, taxpayers may offset gross receipts by the cost of goods sold. Metra Chem Corp. v. Commissioner, 88 T.C. 654, 661 (1987); sec. 1.61-3(a), Income Tax Regs. In order to substantiate claimed cost of goods sold, taxpayers are expected to maintain adequate records. Sec. 6001; sec. 1.6001-1(a), Income Tax Regs.Page: Previous 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 NextLast modified: November 10, 2007
