United States Congress Joint Committee on Taxation is a bicameral committee of the United States Congress charged with providing nonpartisan analysis for tax legislation, the Internal Revenue Service oversight, and revenue estimation. The committee operates at the intersection of United States Senate and United States House of Representatives processes, advising committees such as United States Senate Committee on Finance and United States House Committee on Ways and Means while interacting with agencies including the Department of the Treasury and the Office of Management and Budget.

History

Created during the 69th United States Congress in 1926 amid debates over Revenue Act of 1926 provisions, the committee evolved through interactions with landmark laws such as the Revenue Act of 1935, the Tax Reform Act of 1986, and the Economic Growth and Tax Relief Reconciliation Act of 2001. Its institutional role expanded after reforms linked to the Internal Revenue Service Restructuring and Reform Act of 1998 and the tax controversies surrounding the 1993 budget reconciliation and the 2001 recession. Over decades the committee has produced statutory estimates and technical interpretations that influenced rulings of the United States Supreme Court in tax cases and informed investigations by the Government Accountability Office and the Congressional Budget Office.

The committee comprises ten members apportioned between delegations from the United States Senate and the United States House of Representatives, with membership drawn principally from the United States Senate Committee on Finance, the United States House Committee on Ways and Means, and their ranking members. Leadership is informal but coordinated with chairs of United States Senate Committee on Finance and chairs of United States House Committee on Ways and Means; staff are led by the Chief of Staff or Chief of the Joint Committee who often liaises with the Treasury Secretary, the Director of the Congressional Budget Office, and the Comptroller General of the United States. Members have included prominent legislators tied to major tax measures such as those associated with Bob Packwood, Daniel Patrick Moynihan, and Bill Archer.

Statutorily empowered to provide revenue estimates, the committee issues baseline projections used in budget reconciliation under the Budget Act of 1974 and advises on Pay-As-You-Go Act of 2010 calculations. It prepares tax expenditure estimates related to laws like the Tax Cuts and Jobs Act of 2017 and analyzes the distributional effects of proposals referenced in Congressional Budget Office reports and Government Accountability Office audits. The committee also issues advisory opinions and technical explanations that shape rulemaking by the Department of the Treasury and precedence considered by the United States Tax Court.

Staffed by economists, attorneys, and accountants, the committee produces models and microsimulations that draw on datasets such as Individual Income Tax Return (Form 1040), corporate filings associated with Securities and Exchange Commission, and administrative data from the Internal Revenue Service. Its revenue estimations employ methodologies similar to those used by the Congressional Budget Office and academic centers like the Tax Policy Center and National Bureau of Economic Research, while coordinating on dynamic scoring issues with the Office of Management and Budget and independent analysts at institutions such as Brookings Institution and American Enterprise Institute.

During markup of major measures including the Tax Reform Act of 1986, the committee provides Joint Committee on Taxation explanations, revenue estimates, and technical corrections that influence floor debate in both the United States Senate and the United States House of Representatives. It issues formal cost estimates for amendments under the Byrd Rule during reconciliation and supports drafting of statutory language used in bills shepherded by leaders of Republican Party (United States) and Democratic Party (United States). The committee’s zero-baseline and baseline scoring affects negotiations with the Executive Office of the President and shapes legislative strategies employed by committee chairs such as those from Ways and Means Committee and Senate Finance Committee.

The committee publishes reports and documents that are used by watchdogs like the Government Accountability Office and academics at Harvard University and Columbia University, but it has faced criticism from members of Congress and think tanks including Heritage Foundation and Center on Budget and Policy Priorities for methodology, partisan perception, and the limits of public access to certain working papers. Debates have centered on dynamic scoring, distributional tables, and assumptions about macroeconomic feedback similar to controversies in analyses by the Congressional Budget Office and disputes seen during passage of the Tax Cuts and Jobs Act of 2017. Congressional oversight has included inquiries by the House Committee on Oversight and Reform and the Senate Committee on Homeland Security and Governmental Affairs into data handling and transparency practices.
