Paid administrative leave is an ordinary tool. An agency puts someone on it during an investigation, or a building closure, or a transition. GAO's phrasing is neutral and exact: "an excused absence without loss of pay or charge to leave. It is a cost to taxpayers as employees receive full pay without performing job duties."
In 2025 it became something much larger than a tool.
The numbers
GAO's review of payroll data found that federal agencies' use of paid administrative leave increased by 435 percent from 2023 to 2025. GAO estimates federal agencies in our review spent $9.5 billion in salary costs on paid administrative leave in 2025, a sixfold increase from 2023.
The cause is named in the report's title and in its text: "In 2025, the Office of Personnel Management (OPM) directed agencies to use paid administrative leave to support the deferred resignation program, which generally allowed federal employees to be placed on leave until they resigned or retired by September 30, 2025."
GAO's estimate of that share: "Using program assumptions and internal time and attendance data provided by payroll service providers, GAO calculated about $6.7 billion of that amount was associated with deferred resignation program."
So roughly $6.7 billion of $9.5 billion is the program. The remaining $2.8 billion is everything else administrative leave is used for — and, as the next section shows, some of it is probably not administrative leave at all.
The bucket problem
The sharpest sentence in the report is not about the size of the number. It is about where the number lives.
OPM does not know the actual costs of the paid administrative leave used for workforce reduction efforts, including the deferred resignation program.
Why not: "the paid administrative leave used for workforce reduction efforts is reported with other types of general paid administrative leave." There is no separate code for it.
And the consequence, in GAO's words:
To calculate long-term savings, OPM needs to know short-term costs of paid administrative leave used for these efforts. However, OPM cannot easily and accurately do this... Without a mechanism to track paid administrative leave for workforce reduction efforts, federal leaders may not have the data needed to understand whether government-wide cost saving goals are being met.
GAO notes the stated purpose the program was meant to serve: "One of the administration's stated principles for current workforce reduction efforts is to trim the budget topline by reducing full-time equivalent positions."
The saving and the cost are real, and they are booked in different places. That is not an allegation about anyone's motives. It is a chart of accounts that cannot produce the subtraction.
The data is also noisy, and GAO says which way
GAO found a specific, checkable defect: "GAO found that agencies reported 144 percent more paid administrative leave used in pay periods with a public holiday in 2023 through early 2025."
The interpretation is immediate: "Holidays should not be reported as paid administrative leave, and OPM has issued guidance to help address this data issue." A federal holiday is not an excused absence; it is a holiday. Some agencies were coding it as one anyway.
GAO says this "could overstate the actual amount used" — so its own $9.5 billion carries a stated direction of error, which is worth more than a number with no error attached at all.
OPM has issued guidance going forward. What it will not do is go back: "OPM does not plan to retroactively fix such historical errors in data released to the public." Which means the public dataset for 2023 through early 2025 contains known errors that will stay in it.
What GAO asked for
Two recommendations, both still open as of publication:
- That OPM publicly disclose the data reliability issues that remain unaddressed, so that "users make informed decisions about how to use these data."
- That OPM create a new category of paid administrative leave for workforce reduction efforts, so the cost can be separated from ordinary administrative leave.
Neither asks anyone to change a policy about who may be put on leave. Both ask the government to be able to count what it already did.
