- 50 - The addition is imposed at the rate determined by section 6621.21 Imposition of the tax is mandatory where prepayments of the tax, either through withholding or by making estimated quarterly payments, do not satisfy the specified percentages of total liability required under the statute. Grosshandler v. Commissioner, 75 T.C. 1, 20-21 (1980); see also Swonder v. Commissioner, T.C. Memo. 1994-430. Section 6654 allows no generally available reasonable cause or willful neglect defenses. See Swonder v. Commissioner, supra; cf. sec. 6654(e)(3)(B) (reasonable cause/willful neglect defense allowed for newly retired or disabled individuals). Once respondent determines that petitioner is liable for the addition to tax under section 6654, the burden shifts to petitioner to prove, by a preponderance of the evidence, that respondent's determination was incorrect. Rule 142(a); Register v. Commissioner, T.C. Memo. 1988-390. Petitioner presented no evidence on this issue. He did not pay any estimated income tax in either 1986 or 1987 beyond minimal withholding on the wages reported by Sam Gilbert Associates in 1986 and Fort Apache, Inc. in 1987.22 Therefore, petitioner is liable for the addition to tax imposed by section 6654(a) for both years. 21The rate is the short-term Federal rate for the applicable period plus 3 percentage points. Sec. 6621(a)(2) and (b). 22See infra Tables 9 and 14 in appendix.Page: Previous 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 Next
