Unreimbursed Employee Business Expenses We next consider the unreimbursed employee business expenses petitioners claimed on Schedule A. We begin by outlining the general rules to claim business expenses. In general, all ordinary and necessary expenses paid or incurred in carrying on a trade or business during the taxable year are deductible. Sec. 162(a). Services performed by an employee constitute a trade or business. O’Malley v. Commissioner, 91 T.C. 352, 363-364 (1988); sec. 1.162-17(a), Income Tax Regs. An expense is ordinary for these purposes if it is normal or customary within a particular trade, business, or industry. Deputy v. du Pont, 308 U.S. at 495. An expense is necessary if it is appropriate or helpful for the development of the business. Commissioner v. Heininger, 320 U.S. 467, 471 (1943). Personal, living, or family expenses, on the other hand, are not generally deductible. Sec. 262. If a taxpayer establishes that he or she paid or incurred a deductible business expense but does not establish the amount of the deduction, we may approximate the amount of the allowable deduction, bearing heavily against the taxpayer whose inexactitude is of his or her own making.
