- 5 - lack of substantiation. Although petitioner substantiated $1,514 for insurance, $3,027 for repairs and maintenance expenses, and $898 for utilities, respondent disallowed those expenses as personal in nature. In the notice of deficiency respondent determined that petitioner is entitled to deduct $2,010 as real estate taxes, $12,740 as mortgage interest, and $400 as a charitable contribution deduction on Schedule A, Itemized Deductions. Discussion Section 162(a) allows a taxpayer to deduct all ordinary and necessary expenses paid or incurred in carrying on a trade or business. Under section 280A, however, deductions associated with a home office are generally disallowed unless the home office is used exclusively and regularly as the principal place of business of the taxpayer.4 Petitioner presented no evidence to substantiate deductions claimed for advertising expenses, car and truck expenses, legal/professional expenses, and other expenses which consisted of postal and shipping, business calls and faxes, and computer and software services claimed on Schedule C. Secs. 162, 274(d), 280F(d)(4). Respondent’s determination as to these adjustments is sustained. 4 Petitioner does not argue, nor does the record establish, that petitioner satisfied the requirements of sec. 7491(a).Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: March 27, 2008
