- 16 - and maintain that by filing late, they were merely deferring receipt of their tax refund. Thus, we sustain the addition to tax. Section 6661 Section 6661(a) provides for an addition to tax equal to 25 percent of the amount of any underpayment which is attributable to a substantial understatement of income tax. The amount of the understatement is equal to the excess of the amount of tax that is required to be shown on the return for the taxable year over the amount of the tax actually shown on the return. Woods v. Commissioner, 91 T.C. 88, 94 (1988). An understatement is "substantial" when it exceeds the greater of 10 percent of the tax which is required to be shown on the return or $5,000. Sec. 6661(b)(1). However, the amount of the understatement may be reduced for amounts that the taxpayer adequately discloses or supports with substantial authority. Sec. 6661(b)(2)(B); Mitchell v. Commissioner, T.C. Memo. 1994-242. Petitioners have failed to present any argument or evidence regarding the applicability of either exception. Rather, they contend that no understatement exists. Accordingly, we sustain the addition to tax. Decision will be entered under Rule 155.Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
