- 7 - substantiation submitted for the amounts claimed on the return is for a computer purchased in 1997. Based upon the testimony of petitioner’s husband, this computer was fully depreciated for tax purposes prior to 2000. Accordingly, the miscellaneous business expense deductions for “Computer” are disallowed. In 2001, petitioner claimed a deduction of $1,926 for worthless securities. In 2000, petitioner claimed deductions of $4,462 and $5,621 for “Uranium 616 expense” and “Gold 616 expense”, respectively. In 2000 and 2001, petitioner claimed deductions of $1,647 and $1,649, respectively, under the caption “Oil and gas”. The information submitted by petitioner relative to these items are the copies of checks dated in 1983 and 1984. We found petitioner’s husband’s explanation of these deductions to be unconvincing, and these deductions are disallowed. The other miscellaneous business expenses disallowed by respondent were not adequately substantiated by petitioner, and respondent’s adjustments are sustained. The remaining issue is the penalty under section 6662. Section 6662(a) provides a penalty equal to 20 percent on the portion of the underpayment of tax attributable to a substantial understatement of income tax or to negligence. A substantial understatement of income tax is defined as an understatement of tax that exceeds the greater of 10 percent of the tax required to be shown on the tax return or $5,000. Sec. 6662(d)(1)(A). ForPage: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 10, 2007
