Commissioner, T.C. Memo. 1992-213; Jenkins v. Commissioner, T.C. Memo. 1988-292, affd. without published opinion 880 F.2d 414 (6th Cir. 1989). He is, or certainly should be, familiar with the substantiation requirements of section 274, and he had access to a wide range of tax resources relating to his claimed deductions under sections 162 and 274. Petitioners knew or should have known that they had to substantiate the deductions they claimed and had to establish both the amount and business, as opposed to personal, nature of the expenditures. Accordingly, respondent’s determination is sustained. We have considered the other arguments of the parties, and they are either without merit or not necessary in view of our resolution of the issues in this case. To reflect the foregoing, Decision will be entered under Rule 155.Page: Previous 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43
