- 16 - Commissioner, T.C. Memo. 2003-39; Nichols v. Commissioner, T.C. Memo. 2003-24, affd. 79 Fed. Appx. 282 (9th Cir. 2003). Petitioners raised the issue of whether section 7491(a) applies for the first time in their posttrial brief. Respondent argues that he would be prejudiced if we were to allow petitioners to raise the section 7491(a)(2) requirements issue for the first time on brief because had they raised the issue earlier, respondent could have presented evidence showing that petitioners have not satisfied the requirements. We agree with respondent. See Smith v. Commissioner, T.C. Memo. 2007-368; Deihl v. Commissioner, T.C. Memo. 2005-287. Furthermore, other than the testimony of the examining agent that petitioners provided her with a lot of information, the record contains no specific evidence that petitioners have complied with all of the substantiation and record maintenance requirements or cooperated with respondent’s information requests. Therefore, the record is insufficient for us to find that petitioners have satisfied the requirements of section 7491(a)(2), and we conclude a shift of the burden of proof is not appropriate in this case. II. Whether Petitioners Must Pay Income Tax on FRC’s Income for 1997 Petitioners argue that they are not required to pay income tax on any of FRC’s income or loss for 1997 because collateral estoppel prevents respondent from taxing petitioners in an amount in excess of what they received from the arbitration award andPage: Previous 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 NextLast modified: March 27, 2008
