- 7 - period within which they were obliged to file a petition for redetermination with the Tax Court and that (2) those taxpayers could rely on the computation of that period by the Commissioner. S. Rept. 105-174, at 90 (1998), 1998-3 C.B. 537, 626; see H. Rept. 105-364 (Part 1), at 71 (1997), 1998-3 C.B. 373, 443; see also Rochelle v. Commissioner, 116 T.C. 356, 362-363 (2001), affd. per curiam 293 F.3d 740 (5th Cir. 2002). Thus, if the Commissioner makes a mistake in computing the filing period by overstating it, the last sentence of section 6213(a) serves to enlarge the period of time within which a taxpayer would otherwise have to file a petition for redetermination with this Court. On the other hand, the Commissioner’s mistake in computing the filing period by understating it does not serve to shorten the period of time prescribed by law within which a petition must be filed. Cf. Bush v. Commissioner, T.C. Memo. 2002-33 (notice of deficiency specifying July 4 as the last date to file a petition ignored the provisions of section 7503 regarding time for performance of acts where the last day falls on Saturday, Sunday, or legal holiday), affd. 51 Fed. Appx. 422 (4th Cir. 2002). In short, the 90th day after March 24, 2007, was Friday, June 22, 2007, and by no administrative fiat in the notice of deficiency may respondent make that day any earlier.Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: March 27, 2008
