'State' in the Internal Revenue Code
26 U.S.C. § 7701(a)(10) defines 'State' to include the District of Columbia. The use of 'include' rather than 'mean' has been read in alternate-tax theory as restricting the term to D.C. and federal possessions, excluding the fifty states. Read in tandem with § 7701(c) — the IRC's own construction rule — that reading is foreclosed: 'includes' is non-exclusive, and the fifty states remain within the ordinary meaning of 'State.'
