What Joint Liaison Committee on Taxatio does

The Joint Committee on Taxation (JCT) is a nonpartisan joint committee of the United States Congress, established under the Revenue Act of 1926 and headquartered at 502 Ford House Office Building in Washington, DC. It serves the entire Congress—primarily the tax-writing committees (House Ways and Means and Senate Finance), individual Members, and their staffs—by providing objective technical analysis of proposed tax legislation. Its functions include preparing official revenue estimates for all tax legislation considered by Congress, drafting hearing pamphlets and committee reports, producing technical explanations and Bluebooks, conducting distributional analyses across income groups, reviewing large IRS refund cases exceeding $2 million, and maintaining the only complete legislative history of Federal taxation dating back to the Tariff and Income Tax Act of 1913.

The JCT operates a core analytical platform of highly developed microsimulation tax models—Individual, Corporate, International Cross Border, and Estate and Gift Models—built on large micro-data files drawn from the IRS Statistics of Income Division and supplemented by spreadsheet-based panel models. The staff also performs macroeconomic analysis under House and Senate dynamic scoring rules dating to 2003. Publications are distributed via the jct.gov website, an XML publications feed, and direct confidential delivery to requesting Members; recent outputs include JCX-19-26 on sports industry tax issues and JCX-18-26 on digital asset taxation (2026). Leadership consists of Chief of Staff Thomas A. Barthold and Deputy Chief of Staff Chris Giosa.

The JCT does not generate commercial revenue. It is funded through annual congressional appropriations and provides all estimates and analyses at no cost as part of the legislative process. Requests are submitted on a Member's letterhead to the Chief of Staff and are confidential unless the requesting Member chooses to release them. The committee is chaired on a rotating basis by the chairs of the Senate Finance and House Ways and Means Committees.

Others

• Tax Notes (Tax Analysts): Subscription-based publisher of federal and state tax news, analysis, and primary source documents. Comparable to JCT's publication function in serving tax practitioners and policymakers with legislative and regulatory tax intelligence.
• IRS Statistics of Income (SOI) Division: IRS division that produces statistical analyses of tax return data and serves as the primary data source for JCT's microsimulation models. Directly comparable as a tax data and statistics producer, though an IRS program rather than Congressional support function.

Emerging players

• Tax Policy Center: Joint venture of the Urban Institute and Brookings Institution providing distributional analyses of federal tax proposals. Comparable to JCT's distributional analysis function across income groups, though an academic/policy organization rather than a government entity.
• Tax Foundation: Nonpartisan tax policy think tank producing independent analyses of federal tax proposals. Comparable in tax policy analytic output and modeling capability, though external to government and not empowered to produce official Congressional revenue estimates.
• Penn Wharton Budget Model: Academic budget and tax microsimulation model used to produce revenue and distributional estimates of federal tax proposals. Comparable to JCT's revenue estimating and distributional analysis capabilities, though an independent academic alternative rather than official scorekeeper.

Broad incumbents

• Bloomberg Tax: Commercial provider of tax research, news, and practice tools used by tax professionals, lawmakers, and their staffs. Comparable in serving the broader tax policy ecosystem with analysis and legislative tracking, though a commercial subscription product rather than nonpartisan government entity.
• Government Accountability Office (GAO): Legislative-branch agency conducting audits, investigations, and program evaluations for Congress. Comparable in nonpartisan Congressional support mission, but broader in scope beyond tax and lacking JCT's microsimulation modeling focus.

Direct peers

• Congressional Research Service (CRS): Nonpartisan legislative branch agency providing policy analysis to Members of Congress. Comparable in mission (nonpartisan technical analysis for Congress), customer base (Members and committees), and confidentiality protocols, though broader in policy domain.
• Congressional Budget Office (CBO): Federal legislative-branch agency that produces official cost estimates for all legislation considered by Congress. Directly comparable to JCT as a nonpartisan Congressional scorekeeper, with overlapping microsimulation modeling expertise and a similar statutory mandate under the 1974 Budget Act.
• Office of Tax Analysis (U.S. Treasury): Treasury Department office responsible for official executive-branch analyses of tax policy and revenue estimates. Directly comparable in tax microsimulation modeling capability and analytic mission, though serving the executive rather than legislative branch.
