- 37 - of tax attributable to, among other things, any substantial understatement of income tax. Sec. 6662(a), (b)(2). In the notice of deficiency, respondent determined that the entire underpayment of tax for the 1991 taxable year was due to a substantial understatement of income tax. Petitioners bear the burden of proving that respondent's determination is erroneous. See Rule 142(a). In their briefs, petitioners simply assert that there is no substantial understatement of income tax. On the record before us, we find that respondent's determination of a penalty under section 6662(a) is correct, except to the extent that it relates to respondent's concessions regarding the unexplained bank deposits discussed in supra section III.A. V. Conclusion Respondent's determinations of a deficiency in and penalty on petitioners' Federal income tax for the 1991 taxable year are sustained to the extent set forth in this report. Decision will be entered under Rule 155.Page: Previous 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37
