- 12 - taxpayer must still establish the actual mileage, the time, and the business purpose of each use. Nicely v. Commissioner, T.C. Memo. 2006-172; sec. 1.274-5(j)(2), Income Tax Regs. Petitioner submitted a travel log, consisting of a collection of preprinted forms which he had filled in, showing the details of travel on particular dates. The travel log was not prepared contemporaneously with the claimed business travel but rather was a reconstruction based on petitioner’s recollection of travel during 2003. The travel log was prepared after petitioner had been contacted by respondent’s agents in connection with an audit of petitioner’s 2003 tax return. The travel log was unsupported by any other documentation, such as a calendar or receipts, and petitioner admitted that the log contained several errors. Even if petitioner maintained an office in his home for the convenience of the university (which we find he did not), the travel log does not meet the substantiation requirements of section 274, and petitioner’s use of his automobile for his trips to libraries around the State did not generate any business deduction.6 Petitioner’s claimed transportation expenses reflecting the use of his vehicle to drive from his home to the university were 6At trial, respondent conceded that other expenses for trips out of State and abroad for the purpose of attending conferences and the like are adequately substantiated and are therefore deductible.Page: Previous 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 NextLast modified: November 10, 2007
