A new report from the head of the IRS’s Taxpayer Advocate Service shows that the agency has lost more than one-quarter of its workforce since President Donald Trump assumed office.
The overhaul is consistent with the administration’s effort to slim down the federal government, but it raises questions about the agency’s readiness for the 2026 tax season.
Of the 26,411 employees who left the agency since Jan. 25, more than 17,500 took buyouts through the DOGE-related “fork in the road” resignation offer, formally known as the Deferred Resignation Program.
Another 1,475 exited through early retirement or voluntary separation incentives, while nearly 3,000 departed through standard attrition such as resignation, termination, or death.
National Taxpayer Advocate Erin M. Collins, who heads the Taxpayer Advocate Service, which produced the report, praised the IRS for delivering one of its smoothest filing seasons in recent memory this year. But she warned that the sharp reduction in personnel—particularly in areas such as taxpayer services, IT, and small business operations—could strain the agency in the year ahead.
The report noted that many of the agency’s most experienced leaders were among those who left, compounding operational challenges. Some key preparatory steps—such as hiring and training seasonal workers—had yet to begin as of mid-year, raising concerns about potential gaps when the filing season opens in January 2026.
Critics Assail Downsizing
While proponents of the downsizing initiative argue that it will foster a more efficient and accountable federal bureaucracy, critics say the cuts could hollow out government services.Former IRS Commissioner John Koskinen also criticized the downsizing, calling it “nonsensical” to weaken the agency responsible for collecting revenue needed to run the government—particularly amid calls for deficit reduction.
The watchdog report also flagged potential upcoming budgetary pressures. The Trump administration’s fiscal 2026 budget proposal calls for a 20 percent cut to IRS appropriations, and a total reduction of 37 percent when accounting for the expiration of Inflation Reduction Act funds, the report noted.
“A reduction of that magnitude is likely to impact taxpayers and potentially the revenue collected,” Collins wrote.
Collins urged the administration to lift its hiring freeze and grant direct hiring authority so that the IRS can bring on essential staff in time to prepare for next year’s tax filing season. Without swift action, she warned, taxpayers could face longer wait times, service delays, and greater frustration.
Actual reductions may be even steeper. Several agencies, including the Department of Defense, have announced planned cuts that were not included in the June budget documents. The White House has acknowledged that the published staffing figures “may not reflect all of the management and administrative actions underway or planned in federal agencies.”
