- 8 - 142(a); INDOPCO, Inc. v. Commissioner, 503 U.S. 79, 84 (1992). A taxpayer is required to maintain records sufficient to substantiate deductions claimed on his tax return. Sec. 6001; 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. To establish the amount of time petitioner spent on his rental real estate activities, petitioners introduced a spreadsheet summarizing the work activities he performed on a daily basis for each of his three rental properties (daily work log). The daily work log was not prepared contemporaneously as petitioner performed each activity but was composed by petitioners, purportedly from various receipts and documents, in preparation for trial. Petitioners claim that they have the underlying receipts and documents from which the spreadsheet was prepared, but they did not think it was necessary to bring them to Court for trial or to introduce them into evidence. In the absence of any corroborative evidence, we do not consider the daily work log persuasive. Furthermore, the daily work log merely identifies tasks and services performed by petitioner on a particular day. It does not give any indication or approximation of how much timePage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 Next
