The understatement of income tax resulting from the disallowance of petitioners’ Schedule C deductions, alone, is $5,546, which is greater than 10 percent of the tax petitioners were required to show on their 2001 return. Therefore, we conclude that respondent has met his burden of production for his determination of the accuracy-related penalty based on a substantial understatement of income tax pursuant to section 6662(d)(1)(A). Accordingly, petitioners bear the burden of proving that the accuracy-related penalty should not be imposed with respect to any portion of the underpayment for which they acted with reasonable cause and in good faith. See sec. 6664(c)(1); Higbee v. Commissioner, supra at 446. Some of the claimed deductions, such as those for meals for Mr. Vigil’s family (absent proof that these expenses had a bona fide business purpose), are likely nondeductible family living expenses. See sec. 262; sec. 1.162-2(c), Income Tax Regs. In addition, it should be obvious to any taxpayer exercising ordinary business care and prudence that duplicating automobile expenses (by deducting not only car and truck expenses based on actual costs but also driving expenses calculated using the standard mileage rate) is prohibited.Page: Previous 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 NextLast modified: March 27, 2008
