- 4 - carrying on a trade or business. Generally, no deduction is allowed for personal, living, or family expenses. See sec. 262. The taxpayer must show that any claimed business expenses were incurred primarily for business rather than social reasons. See Rule 142(a); Walliser v. Commissioner, 72 T.C. 433, 437 (1979). To show that the expense was not for personal reasons, the taxpayer must show that the expense was incurred primarily to benefit his business, and there must have been a proximate relationship between the claimed expense and the business. See Walliser v. Commissioner, supra. Where a taxpayer has established that he has incurred a trade or business expense, failure to prove the exact amount of the otherwise deductible item may not always be fatal. Generally, unless precluded by section 274(d), the Court may estimate the amount of such an expense and allow the deduction to that extent. See Finley v. Commissioner, 255 F.2d 128, 133 (10th Cir. 1958), affg. 27 T.C. 413 (1956); Cohan v. Commissioner, 39 F.2d 540, 543-544 (2d Cir. 1930). In order for the Court to estimate the amount of an expense, however, the Court must have some basis upon which an estimate can be made. Vanicek v. Commissioner, 85 T.C. 731, 742-743 (1985). Without such a basis, an allowance would amount to unguided largesse. Williams v. United States, 245 F.2d 559, 560 (5th Cir. 1957).Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 10, 2007
