- 26 - accuracy-related penalty under section 6662(a).24 OPINION Petitioners bear the burden of proving that respondent erred in making the determinations in the notice that remain for our consideration.25 Rule 142(a); Welch v. Helvering, 290 U.S. 111, 115 (1933). We address below the standard of proof required of petitioners in order to satisfy that burden with respect to the December 2, 1999 transaction and the June 14, 2000 transaction. Before considering the December 2, 1999 transaction and the June 14, 2000 transaction, we shall (1) summarize certain princi- ples applicable in determining whether those transactions consti- tute sales for tax purposes by petitioners of lots 5 and 12 and (2) evaluate certain evidence in the record on which petitioners rely. Certain Applicable Principles The determination of whether a purported sale is a sale for tax purposes is a factual determination, Derr v. Commissioner, 77 24Respondent made certain additional determinations in the notice with respect to petitioners’ taxable year 1999 that petitioners do not dispute. Certain of those determinations were favorable to petitioners, and certain others were unfavorable. In addition, respondent made certain additional determinations in the notice with respect to petitioners’ taxable years 1999 and 2000, the resolution of which flows automatically from the resolution of certain other determinations in the notice. 25Petitioners do not claim that the burden of proof shifts to respondent under sec. 7491(a). We conclude that the burden of proof does not shift to respondent under that section.Page: Previous 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 NextLast modified: November 10, 2007
