Bessent's 210-Day Term as Acting IRS Commissioner Lapses in the Middle of Filing Season

Treasury Secretary Scott Bessent's time as acting commissioner of the Internal Revenue Service ran out on March 6, 2026, according to three Senate Democrats who raised the alarm on March 10. In a statement from the Senate Finance Committee minority, Ron Wyden, Chuck Schumer and Elizabeth Warren said no nominee has been sent to the Senate, leaving the agency without confirmed leadership in the middle of filing season.

What changed

Bessent became acting commissioner on August 8, 2025, when President Trump removed Billy Long, who had been confirmed only weeks earlier. The Federal Vacancies Reform Act allows an acting official to serve for 210 days when no nomination is pending. By the senators' count, that period ended March 6.

Day-to-day operations are being run by Frank Bisignano, the Social Security commissioner, who was named to a newly created IRS chief executive officer role in October 2025. The senators argue Congress never authorized that position. They also noted that Kenneth Kies, who has served as acting chief counsel since November while also holding the Senate-confirmed post of assistant secretary for tax policy, faces his own acting-service deadline on June 16, 2026.

The letter describes seven changes in the commissioner or acting commissioner role during 2025, and says most of the IRS's 28 top official positions were vacant or filled on an acting basis as of late 2025.

Why the legal question matters

Reporting by Bloomberg Tax, summarized by TaxProf Blog, notes that actions taken by an official serving in violation of the Vacancies Act can have no force or effect. The practical catch is that someone must sue to test it, and agencies often have another official co-sign actions to limit that risk.

There is also a timing problem for any nominee. The commissioner's term is fixed, and a new appointee would serve only the remainder of former Commissioner Danny Werfel's term, which ends in November 2027. That shrinking window makes a nomination less likely, according to the same reporting.

Who is affected

For most wage earners, refunds and routine processing continue regardless of who holds the title. The stakes are higher for households whose returns depend on guidance that has not yet been written or on examinations that require senior sign-off. The One Big Beautiful Bill Act made sprawling changes, and much of the guidance that affluent filers and business owners are waiting for runs through the commissioner's office and the chief counsel.

What it means for complex filers

Leadership gaps rarely change a tax bill directly. They can change how quickly guidance arrives, how consistently rules are applied and how responsive the agency is when something goes wrong. For owners of pass-through businesses, households with equity compensation or large charitable gifts, and anyone with an open examination or appeal, delays in guidance can mean filing positions taken without final rules.

• Filers relying on provisions that still lack formal guidance may want to document the basis for their positions carefully and discuss extension timing with a CPA.
• Taxpayers with pending audits, appeals or private letter ruling requests may see slower responses and often ask their representatives how to plan around that.
• Households expecting correspondence or notices may benefit from keeping records organized, since resolution can take longer when senior approvals are backlogged.

What to watch

The immediate question is how Treasury describes who is exercising the commissioner's authority now that the acting period has lapsed, and whether a nominee is named. Beyond that, watch the June 16 deadline for the acting chief counsel and the pace of guidance on last year's tax law as the April 15 filing deadline approaches.
