- 4 - registered mail to the taxpayer at the taxpayer’s last known address. Id. at 261-262. The effect of the “shall be sufficient” language in section 6212(b)(1) is to provide a safe harbor assuring the Commissioner that the notice of deficiency is valid for these purposes even if the notice is not received by the taxpayer before the end of the petition period. Mulvania v. Commissioner, 81 T.C. 65, 67-68 (1983); Zenco Engineering Corp. v. Commissioner, 75 T.C. 318, 321-322 (1980), affd. without published opinion 673 F.2d 1332 (7th Cir. 1981). Because of the Court’s concern about jurisdiction, we directed the parties to consider whether respondent’s use of an incorrect ZIP Code in addressing the notice of determination affected the validity of the notice of determination. See Normac, Inc. & Normac International v. Commissioner, 90 T.C. 142, 146-147 (1988). The unrebutted evidence submitted by respondent is that in the instant case the notice of determination was attempted to be delivered to the correct address and ZIP Code. The error in the ZIP Code shown on the notice of determination envelope was corrected by the U.S. Postal Service and did not affect the timely attempted delivery of the notice of determination. Consequently, we find that the notice of determination was sent to petitioner’s last known address.Page: Previous 1 2 3 4 5 6 NextLast modified: November 10, 2007
