When people hear “IRS cuts,” they usually picture fewer audits and a looser enforcement posture. The newer question is more pointed: did workforce reductions actually cost the government money?
Here is one striking data point. Revenue collected from IRS examinations fell 35%, from about $10 billion in fiscal 2024 to $6.5 billion in fiscal 2025, during a period when the agency was undergoing steep workforce reductions that ultimately cut examination and collection staffing by nearly 10,000 employees, as flagged by a Treasury watchdog.
It is tempting to treat that as a clean cause-and-effect story. But the public numbers here do not, by themselves, show why the change happened. What they do show is timing: a large drop in examination-related collections occurred while staffing was being reduced.

What we know
The core sequence is straightforward:
- Revenue collected from IRS examinations fell from about $10 billion (fiscal 2024) to about $6.5 billion (fiscal 2025).
- That is a 35% drop.
- The IRS was undergoing steep workforce reductions that ultimately cut examination and collection staffing by nearly 10,000 employees.
That is enough to say there was a sharp decline during a sharp staffing drawdown. It is not enough, on its own, to prove causation or to show whether collections were permanently lost versus shifted later in time.
Why staffing comes up
Even without getting into the mechanics of how examinations work, the basic logic is simple: fewer employees generally means less capacity to do work. If examination and collection staffing shrinks, the amount of work the agency can push through those functions can change as well.
Still, the safest reading of the public figures is correlation, not a final verdict. The revenue drop happened while staffing was being reduced, and that overlap matters. The figures alone do not tell you what else changed at the same time.
Constitutional basics
The Constitution does not mention the IRS. It does provide the structure that makes federal taxation, appropriations, and administration possible.
At the highest level, tax administration sits at the intersection of three constitutional ideas:
- Taxing power. The federal government has authority to raise revenue through taxation.
- Appropriations. Agencies operate at the scale Congress funds.
- Executive enforcement. The Executive Branch carries out the laws through departments and agencies.
That architecture is why staffing levels are never just management. They are a policy choice about how much administrative capacity the federal government will maintain to carry out laws that are already on the books.
The broader workforce picture
The IRS numbers appeared amid a much wider effort to shrink the federal workforce. As of August, federal government employment stood at 2.67 million, down from just over 3 million when President Donald Trump took office, the lowest level since 1966, per Bureau of Labor Statistics data. Not included in that headcount are roughly 1.35 million armed services members and approximately 100,000 intelligence agency employees.
Cutting the size of the federal workforce, a project eventually spearheaded by the Department of Government Efficiency and the Office of Personnel Management, was a major campaign promise during Trump’s 2024 run.
Not all agencies have been hit the same. The Departments of Education, Agriculture and Housing and Urban Development have been cut particularly hard, while headcount at the Department of Homeland Security has remained largely unchanged.
Savings claims and real costs
The administration has estimated the cuts will produce significant savings, with OPM projecting that its Deferred Resignation Program alone will save more than $20 billion a year.
But reductions have also come with costs. The Government Accountability Office found agencies spent about $6.7 billion paying employees who took part in the Deferred Resignation Program, which allowed many of them to stop working while still collecting a paycheck until they officially left government. The Partnership for Public Service estimated the government spent $12.1 million rehiring workers who had previously been fired during the administration’s workforce reductions.
And reduced headcount does not automatically translate into reduced spending. Despite the cuts, most of which happened during the president’s first year in office, the administration spent 3% more on federal salaries during its first year in power than the Biden administration did during its initial year.
Policy backdrop
The staffing debate also follows a major recent investment. Former President Joe Biden secured nearly $80 billion in 2022 for the IRS over 10 years to upgrade its systems, improve taxpayer service and hire more staff, including enforcement personnel.
The Trump administration has also proposed further IRS cuts for 2027, keeping questions about enforcement capacity and collections on the table.
What to ask next
If you are trying to evaluate whether IRS workforce reductions reduced examination-related collections in a way that matters for the federal budget, focus on questions the headline numbers cannot answer:
- What changed in results? Did collections fall because fewer matters were completed, because the mix of work changed, or for other reasons not visible in the topline figure?
- What spending actually changed? OPM projected more than $20 billion a year in savings from the Deferred Resignation Program alone, but GAO also identified $6.7 billion in program pay costs, and rehiring costs were estimated at $12.1 million.
- What is the long-term plan? Further IRS cuts have been proposed for 2027, which could change capacity again depending on what functions are preserved.
The Constitution does not answer those questions for us. It assigns who must answer them. Congress decides what to fund. The Executive Branch decides how to manage what it is given. And the public decides whether the results match the promises.
The bottom line
The available figures point to a clear overlap in timing: revenue collected from IRS examinations fell 35%, from about $10 billion in fiscal 2024 to about $6.5 billion in fiscal 2025, during steep workforce reductions that ultimately cut IRS examination and collection staffing by nearly 10,000 employees.
That is a strong signal that examination-related collections declined during a period when enforcement staffing was being reduced. Whether the net effect was budget savings or budget loss is a broader accounting question, and one the headline metric cannot answer on its own.
