- 11 - is reasonable if it “harmonizes with the plain language of the statute, its origin, and its purpose.” Id. at 477. Following its decision in National Muffler, the Supreme Court decided Chevron U.S.A., Inc. v. Natural Res. Def. Council, Inc., 467 U.S. 837 (1984). In Chevron, the Court stated that when reviewing an agency’s regulatory implementation of a statute, we look first to whether Congress has directly spoken to the precise question at issue. Id. at 842. If congressional intent is clear, our inquiry ends, and we apply the unambiguously expressed intent of Congress. Id. at 842-843. However, if congressional intent is not clear, the question is whether the regulation is based on a permissible construction of the statute. Id. This Court has, on a number of occasions, considered Chevron’s effect on National Muffler and the review of interpretive tax regulations. See, e.g., Swallows Holding, Ltd. v. Commissioner, 126 T.C. 96, 131 (2006) (discussing the review of Federal tax regulations under National Muffler in relation to Chevron and stating that Chevron restated National Muffler in a more practical two-part test); Cent. Pa. Sav. Association & Subs. v. Commissioner, 104 T.C. 384, 392 (1995) (same) (noting the Supreme Court’s application of National Muffler after Chevron). Whether our analysis is guided by National Muffler or by Chevron, the result would be the same.Page: Previous 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 NextLast modified: November 10, 2007
