- 31 - Mich. v. Commissioner, 353 U.S. 180, 189-190 (1957); Brown v. Helvering, 291 U.S. 193, 203 (1934). Taxpayers challenging the Commissioner's authority must prove that the Commissioner's determination is "clearly unlawful" or "plainly arbitrary". Thor Power Tool Co. v. Commissioner, supra at 532-533. The Commissioner's authority under section 446(b) encompasses overall methods of accounting, as well as specific methods utilized to report any item of income or expense. Id. at 531; Ford Motor Co. v. Commissioner, 102 T.C. at 100; Prabel v. Commissioner, 91 T.C. 1101, 1112-1113 (1988), affd. 882 F.2d 820 (3d Cir. 1989); sec. 1.446-1(a), Income Tax Regs. The fact that the Commissioner possesses broad authority under section 446(b) does not mean that the Commissioner can change a taxpayer's method of accounting with impunity. See, e.g., Prabel v. Commissioner, supra at 1112-1113. Thus, for example, if a taxpayer uses a method of accounting that clearly reflects income, the Commissioner may not require a change to another method merely because the Commissioner believes that the latter method will reflect income more clearly.
