Regulations are laws made by an executive branch agency under the authority of a statute passed by Congress. Regulations are first published in the Federal Register. The Treasury Department issues three types of administrative regulations: proposed, temporary and final. Temporary regulations are issued to provide guidance to tax payers on new tax provisions. They do not require a comment period and are effective immediately upon publication. Final and temporary regulations are first published as Treasury Decisions, which are recognized by a four digit citation, i.e. T.D. 8860 and a description of the purpose and content of the new regulation. Upon codification, regulations are assigned a prefix corresponding to the type of tax provision as indicated.
