IRS Audit Collections Decline sharply Following Workforce Reductions
Washington, Wednesday, 2 September 2026.
Internal Revenue Service audit revenue dropped 35% to $6.5 billion in fiscal year 2025 after federal workforce reductions eliminated nearly one-third of the agency’s dedicated tax enforcement personnel.
Enforcement Capacity and Revenue Loss
The Treasury Inspector General for Tax Administration (TIGTA) reported on August 31, 2026, that audit revenue fell to $6.5 billion in fiscal year 2025, down from $10 billion in fiscal year 2024 [2][3]. This represents a decline of 35 percent, a drop attributed to significant workforce reductions that began in January 2025 under the Trump administration [1][4]. The agency lost approximately 30% of its audit-dedicated staff during this period, with nearly 10,000 enforcement workers leaving the agency [2][3].
Consequently, examinations of individuals earning over $400,000 decreased by 26% in fiscal year 2025, while audits of new business partnerships fell by 30% [2]. Despite the decline in audit-specific revenue, total federal tax revenue reached a record $5.3 trillion in the last fiscal year, driven largely by automatic withholding and economic performance [3][5]. However, the IRS estimates an annual tax gap of approximately $700 billion in unpaid taxes under existing law, highlighting the potential revenue loss from reduced enforcement capacity [3].
Political Responses and Funding Reversals
Congressional Democrats and former President Joe Biden had previously authorized approximately $80 billion in additional IRS funding, including more than $45 billion for enforcement, which was projected to yield around $560 billion in federal revenue over a decade [1][2]. Following President Trump’s second-term directive to reduce the federal workforce, much of this funding was rescinded, reversing efforts to bolster the agency [3][4]. Representative Don Beyer (D-Va.) stated, “Trump gutted the IRS and wealthy tax cheats are reaping the benefits,” emphasizing the impact on tax compliance [1].
Senator Elizabeth Warren (D-Mass.) echoed these concerns, noting that gutting the IRS is a win for wealthy tax cheats and a loss for working people who play by the rules [2]. The Institute on Taxation and Economic Policy noted that the richest Americans benefit most when the IRS lacks staff to dedicate to audits [1]. Natasha Sarin, President of Yale University’s Budget Lab, remarked that if auditors are removed, less money is raised from audits, identifying tax cheats as the winners and rule-followers as the losers [1][4].
Operational Shifts and Future Projections
IRS CEO Frank Bisignano dismissed concerns about the agency losing tens of thousands of employees, asserting that advanced data and analytic strategies allow the IRS to catch instances of tax evasion that would have been undetectable previously [2][3]. Administration officials claim artificial intelligence technology will improve audit selection and investigation efficiency, though specific implementation plans remain undisclosed [3][4]. However, the Treasury Inspector General for Tax Administration expressed concern about how staffing losses are impacting the IRS’s ability to ensure that it meets department priorities [2].
Looking ahead, the Trump administration has proposed further IRS budget cuts for 2027, while experts warn that current staffing levels for revenue agents are at their lowest since the 1950s [2]. Tax analysts with the Center on Budget and Policy Priorities noted that research shows every dollar spent on IRS tax enforcement raises multiple dollars in revenue, meaning cuts add to the deficit [2]. The IRS closed 497,621 audits in fiscal year 2025, recommending $26.8 billion in additional tax, but coverage remains uneven across income levels [5].
