The IRS slashed its auditing staff final yr in what was billed as a cost-cutting transfer, but when the trouble was designed to enhance the federal government’s backside line, it has backfired.
A new report from the Treasury Department’s Inspector General for Tax Administration exhibits that income from audits plunged 35% in fiscal yr 2025, that means billions of {dollars} in taxes went un-collected. The drop coincides with a 27% lower in enforcement and assortment staffing on the IRS, as a part of Elon Musk’s marketing campaign to spice up authorities effectivity.
“The downstream effects of these reductions are likely to become more apparent over time,” the Inspector General wrote.
The IRS had beefed up its auditing ranks throughout the Biden administration, in an effort to gather extra of the estimated $696 billion {dollars} in taxes that go unpaid yearly, largely because of folks and companies that under-report their earnings.
The elevated staffing led to a 41% enhance in audit-related income in 2024 — however that was largely reversed final yr. More than 25,000 IRS staff have been laid off or took early retirement in 2025, together with about 3,600 tax examiners.
The loss in tax income from decreased audit exercise outweighs any financial savings from decreased staffing on the tax-collection company.
“Defunding the IRS is not a money-saving proposition because you have fewer employees,” says Natasha Sarin, who served as a counselor on tax coverage to former Treasury Secretary Janet Yellen. “It is a money-losing one, because you do a less good job of collecting taxes.”
Audits generated $10 billion in tax income in fiscal yr 2024 however that dropped to $6.5 billion in 2025.
Tax audits have been a software to extend compliance
The Inspector General notes that the general lack of income might be bigger, since tax audits are primarily designed to advertise voluntary tax compliance by filers eager to keep away from one.
“You’re less likely to speed when you know that there’s a cop on the beat,” says Sarin, who’s now a professor at Yale Law School.
IRS Chief Executive Officer Frank Bisignano defended the company’s tax enforcement document. Bisignano instructed lawmakers earlier this yr the company is utilizing expertise to focus on its tax audits extra effectively.
The elevated staffing on the IRS beneath the Biden administration was geared toward bringing elevated scrutiny to rich people and partnerships. That fell off sharply as 1000’s of auditors have been let go. Audits of partnerships fell 76% between 2023 and 2025.
“Disproportionately, this is about the tip-top of the [income] distribution,” Sarin says. “Something like the top 1% of earners are responsible for something like a third of the tax gap.”
Staffing ranges on the IRS continued to say no within the first 4 months of the present fiscal yr. The Trump administration has known as for extra cuts in company funding in 2027.
