IRS loses 31% of auditors nationwide

Summary

By the end of March 2025, the IRS had lost approximately 3,600 tax auditors - 31% of all revenue agents - through layoffs and deferred resignations during DOGE's cost-cutting push, according to a May 2025 Treasury Inspector General for Tax Administration report. Plans at the time called for trimming as much as 40% of the IRS workforce in 2025.

What happened

Auditors, customer service staff, IT personnel, and enforcement specialists departed en masse. A Treasury Inspector General for Tax Administration report (released May 2, 2025) found that the IRS lost 31% of revenue agents in the first months of 2025. The Yale Budget Lab projected $323 billion in forfeited revenue over the decade from reduced compliance and auditing.

Impact on the United States

Revenue agents typically handle cases involving wealthy taxpayers or corporations, experts told CBS News, so losing nearly a third of them weakens enforcement for those taxpayers; one expert warned that taxpayers who see little risk of audit may stop paying or filing. The federal deficit grows as IRS capacity shrinks. Every $1 spent auditing the top 0.1% of earners can return about $26 in tax revenue, according to an analysis by the advocacy group Better IRS cited by CBS News.

Documented effects

1. May 2025IRS lost approximately 3,600 revenue agents (31%) in the first three months of 2025, per a Treasury Inspector General for Tax Administration report issued May 2, 2025.[1]
2. Yale Budget Lab projected $323 billion in forfeited tax revenue over ten years from reduced IRS auditing and compliance activity.[1]
3. Apr 2026An updated Yale Budget Lab analysis (April 2026) estimated that the reduction of almost 28,000 IRS staff in 2025 decreases federal revenue by $597.8 billion over 2026-2035.[3]

Why this is rated severe

The loss of 31% of revenue agents, which the Yale Budget Lab projects will cost hundreds of billions of dollars in forgone revenue over a decade, is a severe fiscal harm.

1. Sep 29, 2026CorrectedDate

   The TIGTA report (released May 2, 2025) covered losses through March 2025, not May: 31% of revenue agents, about 3,600 auditors, left in the first three months of 2025. The entry's "up to 20%" workforce-cut figure was unsupported; CBS News reported plans to trim as much as 40% of the IRS workforce in 2025.[1]

2. Sep 29, 2026CorrectedSource

   The Yale Budget Lab $323 billion estimate is reported in the CBS News source, which is now cited for it. The Center on Budget and Policy Priorities is a specialist policy-analysis group and is relabeled Tier 3.[1]

3. Sep 29, 2026ClarifiedKey facts

   The "$26 per $1" audit-return figure comes from an analysis by Better IRS, an advocacy group, as cited by CBS News; it is now attributed.[1]

4. Sep 29, 2026UpdatedFigure

   In an updated April 2026 analysis, the Yale Budget Lab estimated that the reduction of almost 28,000 IRS staff in 2025 decreases federal revenue by $597.8 billion over 2026-2035, up from its earlier $323 billion estimate.[3]

5. Sep 29, 2026CorrectedWhat happened

   Removed two statements no cited source supports: that phone wait times grew dramatically and that IRS staff were told they lacked time to review certain cases. The entry also stated as fact that reduced enforcement disproportionately benefits the wealthy; it now attributes the point as CBS News reported it: revenue agents typically handle cases involving wealthy taxpayers or corporations, experts said. The summary card no longer calls the cuts 'DOGE layoffs' - CBS reports the auditors left through deferred resignation or firing during DOGE's cost-cutting push.[1]

6. Sep 29, 2026CorrectedSeverity rationale

   The severity rationale called the revenue loss 'realized', but the figure is a Yale Budget Lab projection; it now says so. Severity unchanged.[1][3]

   Previously

   Loss of 31% of auditors projected to cost hundreds of billions in uncollected revenue, a severe and realized fiscal harm to the Treasury.

   Now

   The loss of 31% of revenue agents, which the Yale Budget Lab projects will cost hundreds of billions of dollars in forgone revenue over a decade, is a severe fiscal harm.

7. Sep 29, 2026CorrectedCost estimate

   The booked so-far IRS figure was a modeled estimate with no published source. It now uses the Yale Budget Lab's own year-by-year table: $23.6B net for fiscal 2026 ($27.5B lost revenue minus $3.9B payroll savings), of which three quarters ($17.7B) is booked through mid-2026. The 10-year figure ($597.8B) is unchanged. The 15-year figure was built on a wrong late-decade run-rate ($60B/yr); Yale's table shows $97.2B in 2035, which we now hold flat through 2040.

   Previously

   $125.5B net so far ($130B lost, $4.5B saved); $850B through 2040

   Now

   $17.7B net so far ($20.6B lost, $2.9B saved); $1.08T through 2040
