The IRS Collected More Revenue With a Far Smaller Workforce in Fiscal Year 2025
A side-by-side read of the fiscal year 2025 and 2024 Data Books shows a leaner, more automated IRS, with a few numbers that matter if you hold foreign accounts or have unfiled returns.
The IRS released its fiscal year 2025 Data Book on June 5, 2026, and the year-over-year story is striking: the agency collected more than $5.3 trillion, up from $5.1 trillion the year before, while its staff in pay status shrank by nearly 19%, from 99,628 employees to 80,967. The report on IRS.gov shows the agency leaned harder on automation and analytics to close that gap, saying expanded technology now helps it “identify high-risk areas of non-compliance and tax fraud.” For Americans abroad, the headline is simple: fewer auditors did not mean looser enforcement. Here is the year-over-year review, the most interesting finds, and what they mean for your filing.
Revenue Climbed While the Workforce Shrank
The clearest finding in the side-by-side is the widening gap between output and staffing. Collections rose even as the agency operated with thousands fewer people.
| Measure | FY 2024 | FY 2025 |
|---|---|---|
| Revenue collected | $5.1 trillion | More than $5.3 trillion |
| Returns and documents processed | More than 266 million | 271.4 million |
| Employees in pay status (fiscal year-end) | 99,628 | 80,967 |
The IRS ran on $19.0 billion in expenditures and 95,226 full-time equivalent positions in fiscal year 2025. A smaller team collecting more revenue is the through-line of the entire report.
Human Audits Slipped, but Automated Enforcement Did the Heavy Lifting
This is the most important compliance finding. Traditional, human-driven audits declined slightly year over year, while automated programs closed far more cases than auditors ever could by hand.
| Enforcement measure | FY 2024 | FY 2025 |
|---|---|---|
| Tax-return audits closed | 505,514 | 497,621 |
| Recommended additional tax from audits | $29.0 billion | $26.8 billion |
The eye-opener sits outside that table. In fiscal year 2025, the IRS closed 987,460 cases through its Automated Underreporter Program, resulting in $5.9 billion in additional assessments, and another 592,773 cases through its Automated Substitute for Return Program, yielding close to $2.9 billion. In other words, automated matching closed roughly twice as many cases as every hand-worked audit combined. The agency also assessed $29.6 billion in additional tax tied to returns that were not filed on time.
Taxpayers Kept Shifting Online
The service side of the Data Book points in the same direction: fewer phone calls, more self-service. There were nearly 417 million “Where’s My Refund?” inquiries, up 9% from fiscal year 2024, while IRS.gov logged 958.9 million visits and 590.7 million file downloads. Live phone assistance fell to about 18.6 million calls, down from roughly 20 million the prior year. A digital-first agency is processing more interactions through software, which is the same infrastructure that powers its compliance matching.
What These Findings Mean for Americans Abroad
- Automation does not skip foreign accounts. Foreign banks already report U.S. account holders to the IRS under FATCA. As the agency improves how it cross-checks that incoming data against filed returns, gaps that once slipped through become easier to flag, regardless of how many auditors are on staff. A recent federal audit of FATCA enforcement showed how central this data has become.
- Unfiled returns are a standing target. That $29.6 billion in assessed penalties for late or missing returns is a reminder that the automated substitute-for-return machine keeps running even when staffing is down.
The finding matters most if you are:
- A late filer or accidental American who has never filed an FBAR.
- An optimizer holding foreign investment or retirement accounts that may trigger Form 8938 reporting.
- A digital nomad moving money through foreign banks across several countries.
- A retiree abroad drawing a foreign pension or holding accounts above the reporting thresholds.
Steps to Take Now
- Confirm whether your foreign accounts crossed the $10,000 FBAR threshold or the Form 8938 thresholds in any recent year.
- If you are behind, review the Streamlined Filing Compliance Procedures, which let eligible taxpayers catch up with reduced or no penalties when the omission was non-willful.
- Read the real audit risk for expats so you can weigh your exposure with facts.
- Keep organized records of your foreign account balances and income year to year.
