I have substantially revised the legislative history discussion in my Federal Tax Procedure Working Draft for the 2026 editions (Student and Practitioner) to be published on SSRN in early August 2026. As currently revised, the text (without footnotes as it will appear in the Student Edition, although those wanting the draft with footnotes in the Practitioner Edition may view it here):
(5) On Legislative History.
I noted above the controversy between textualists and purposivists over the role that legislative history should play in statutory interpretation. Legislative history is the course of congressional consideration in identifying the need for legislation, drafting or revising the bills (the “drafting history” for enacted statutory text), expressions by persons involved in the process as to how they understood the text of the bills, and the final statutory text. The principal sources of legislative history for statutes are the drafting history and the committee reports which I discuss below. (For tax legislation, the legislative history may also include proposals from Treasury (analogous to drafting history) and Treasury’s explanation of the proposals, most commonly along with Treasury’s annual budget request with tax proposals referred to as the Green Book.) Other sources include committee hearings, statements made on the floor of Congress in debating the legislation, and submissions to Congress by the executive branch. There is a long and substantial history of judicial use of legislative history in statutory interpretation, particularly in the tax area.
Legislative history is a broad term, with some legislative history more persuasive than others (at least for those willing to consider legislative history). In terms of the legislative process and reliable indicators of the meaning of statutory text, the committee reports accompanying legislation are generally viewed as a reliable form of legislative history (eclipsed only by conference committee reports discussed below). In both houses, proposed legislation is generally first considered substantively in committees which generally give the most detailed consideration of proposed statutory text; those committees often hold hearings to discuss legislative proposals and then prepare reports explaining the proposed statutory text that they send to the floors of their respective Houses. The meaning of particular statutory text that is then enacted may be discussed in those hearings or in the committee reports.
For tax legislation, because of the historic influence of the tax writing committees and their staffs and the assistance of the Joint Committee on Taxation (“JCT”), the committee reports of the House Ways and Means Committee and the Senate Finance Committee have been the most frequently used legislative history guide to interpreting the statutory text. Often said to rank even higher than committee reports in authoritativeness is the particular form of legislative history accompanying and explaining statutory text produced in a Conference Committee to work out differences in legislation between the two Houses of Congress. In considering legislative history in a particular case, it is important to understand the legislative processes that produced the legislative history and whether those processes make the legislative history a reliable indicator of the actual or deemed meaning of the statutory text.
