The series preserves in permanent form, the regulations promulgated by the Treasury Department that interpret statutory provisions relating to income, estate, gift, and employment taxes, that illustrate methods of compliance, and that govern practice before the Internal Revenue Service. The regulations are codified in Code of Federal Regulations, Title 26—Internal Revenue, or Title 31—Money and Finance, and the Internal Revenue Code references are identical to 26 U.S.C.A. sections. These volumes contain regulations adopted through December 31, 2025.
