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.
According to the June 25 report, the IRS workforce has dropped from 102,113 employees to 75,702 since January—a roughly 26 percent reduction. The majority of those departures came through voluntary exit programs rolled out by the Department of Government Efficiency (DOGE), a Trump administration initiative to shrink the federal workforce, boost bureaucratic efficiency, and reduce deficits.
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 2025 filing season was one of the most successful filing seasons in recent memory,” Collins said in a statement. “But with the IRS workforce reduced by 26 [percent] and significant tax law changes on the horizon, there are risks to next year’s filing season. It is critical that the IRS begin to take steps now to prepare.”
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.
The staffing reductions are part of a broader Trump administration push to reduce the size of the federal bureaucracy. A February executive order called for a “critical transformation” of the civil service and instructed agencies to root out what it described as “waste, bloat, and insularity.”
A subsequent memorandum from the Office of Management and Budget laid out plans for deep workforce cuts across non-defense agencies.
If we only knew half of what our government is wasting we would be furious
