Senate Advances IRS Tax Administration Reform

A bipartisan bill now before the Senate Finance Committee proposes a broad overhaul of how the IRS communicates with taxpayers, resolves disputes, and enforces compliance. Introduced as S. 3931, the Taxpayer Assistance and Service (TAS) Act was referred to the committee on February 26, 2026, after an earlier discussion draft drew public comment through March 2025. The bill contains more than 60 provisions spanning ten titles, roughly 40 of which reflect recommendations from the National Taxpayer Advocate.

Bill Targets Notices, Penalties, and Digital Tools

The legislation focuses on IRS operations rather than tax rates or deductions. Key provisions would require clearer math-error notices that explain the specific issue and response deadlines, mandate written supervisory approval before certain penalties are issued, and expand online account tools so taxpayers can track refund status and correspondence backlogs in real time. Additional measures would push the IRS to accelerate scanning and digitization of paper-filed returns and correspondence, reducing reliance on manual transcription.

The bill would also strengthen the independence of the National Taxpayer Advocate and the IRS Independent Office of Appeals. Under the proposal, Appeals would gain authority to hire its own attorneys, separate from IRS Chief Counsel, to preserve its independence from the enforcement function. Taxpayers would gain broader access to appeals in select cases, while the Tax Court would receive expanded authority over refund disputes, collection due process cases, and innocent spouse reviews.

IRS Backlog and Staff Losses Drive Legislative Push

Operational strain at the IRS is a central motivator. A March 2026 Government Accountability Office report found the agency's correspondence backlog remained above pre-pandemic levels through 2025, even as 17,047 employees — roughly 17 percent of the workforce — departed through resignation and early-retirement programs. The GAO noted that the IRS still lacked a formal plan to reduce the backlog and recommended that the agency develop one alongside an updated strategic workforce plan.

Treasury officials have separately outlined modernization priorities, including redesigned notices, paperless processing, and expanded callback options. The TAS Act aligns with many of those goals. It draws heavily from longstanding recommendations by the National Taxpayer Advocate, whose mid-year report to Congress flagged the risks posed by a 26 percent workforce reduction heading into the 2026 filing season.

Provisions Reshape Rights for Taxpayers and Practitioners

For individual taxpayers, the proposed changes could simplify notices, reduce procedural surprises during audits, and open new avenues to challenge IRS positions through appeals or Tax Court. The bill also reinforces protections under the Taxpayer Bill of Rights, including the rights to be informed, to appeal, and to finality. A new requirement would compel the IRS to issue a determination on refund claims within 12 months, a significant reduction from the 36-month window in the earlier discussion draft.

Tax professionals face different implications. Provisions addressing preparer standards, PTIN procedures, and refund-claim explanations could raise documentation and compliance expectations. The bill would impose new penalties on ghost preparers and make willful failure to furnish a valid PTIN a felony offense. Industry groups, including the American Institute of CPAs, the National Association of Enrolled Agents, and the National Taxpayers Union, have voiced early support, calling the bill a needed modernization of outdated processes.

Bill Heads to Committee Review and Markup

The legislation now follows a standard path: committee review, possible hearings or markup, and eventual floor consideration. The Joint Committee on Taxation will prepare revenue estimates, and the Congressional Budget Office will issue a cost estimate if the full committee advances the measure. Stakeholders can monitor progress through official channels of the Senate Finance Committee and participate in any future comment periods.
