- 9 - B. Substantiation Taxpayers must maintain records sufficient to enable the Commissioner to determine their correct tax liability. Sec. 6001; Higbee v. Commissioner, 116 T.C. 438, 440 (2001); sec. 1.6001-1(a), Income Tax Regs. Taxpayers must “keep such permanent books of account or records * * * as are sufficient to establish the amount of gross income, deductions, credits, or other matters required to be shown by such person in any return of such tax or information.” Sec. 1.6001-1(a), Income Tax Regs. The notice of deficiency in this matter, combined with information on the attached Form 4549A and Form 886-A, adequately reveals that respondent disallowed petitioner’s Schedule C deductions because of petitioner’s failure to substantiate those deductions. As discussed supra, the Form 886-A states that respondent disallowed the Schedule C expense amounts shown on petitioner’s 2001 and 2002 returns because petitioner failed to provide respondent with “supporting information”. The Form 886-A also states that petitioner “must establish that [his claimed deductions have] met all requirements of the law.” This substantially corresponds both with the language of section 6001 and the regulations issued thereunder, and the principles underlying section 6001. Petitioner therefore bears the burden of proof with respect to substantiating his claimed business deductions.
