- 6 - Other Schedule C Activities There were no sales of timber or firewood with respect to petitioner’s timber and firewood sales activity for 1994, because “the thing fell apart”. His “venture capital” health food and resort enterprise “never got off the ground.” The only items in petitioner’s possession to show his involvement in an oil and gas venture were copies of two uncleared checks that he showed to respondent’s counsel before trial. Discussion The Commissioner’s deficiency determinations are presumed correct, and taxpayers generally have the burden of proving that the determinations are incorrect. Rule 142(a); Welch v. Helvering, 290 U.S. 111, 115 (1933). Under certain circumstances, however, section 7491(a) may shift the burden to the Commissioner with respect to a factual issue affecting liability for tax. Petitioner did not present evidence or argument that he satisfied the requirements of section 7491(a), and, therefore, the burden of proof does not shift to respondent. Deductions for Dependency Exemptions Petitioner argues that he is entitled to dependency exemption deductions for his son and daughter for the years at issue and for Stacy Brown for 1994 and 1995. Section 151(c)(1) allows a taxpayer to claim an exemption deduction for each dependent as defined in section 152 whosePage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 10, 2007
