A large number of IRS employees have taken a buyout deal from the Trump administration, choosing to leave their jobs with full pay and benefits through the end of September, reports Reuters.

According to two IRS sources who spoke to Reuters, over 22,000 workers have accepted the administration’s deferred resignation program, which was offered to federal employees earlier this month. Most of those who accepted have reportedly been told they are not required to report to work during their final months on the payroll.

The IRS had about 100,000 employees when Trump returned to office. Since then, the agency has seen the dismissal of 7,000 probationary employees earlier this year, followed by another 5,000 resigning or retiring in the past three months. Under President Joe Biden, the IRS added about 20,000 workers as part of a broader agency expansion.

Across the entire civilian federal workforce—around 2.3 million employees—roughly 200,000 have left through a mix of resignations, layoffs, and buyouts since January.

The leadership at the IRS has also seen major changes. Acting IRS Commissioner Melanie Krause resigned earlier in April, becoming the third agency head to step down in just a few months. Her departure came shortly after the IRS entered into a data-sharing agreement with the Department of Homeland Security. The agreement allows the IRS to share data with Immigration and Customs Enforcement (ICE) in an effort to help track illegal immigrants.

Some watchdog groups are voicing concerns over what this mass exit could mean for the agency’s ability to do its job effectively.

“I worry that this Administration’s destructive initiatives at IRS will cost the federal government hundreds of billions of dollars in revenue while putting taxpayer services and privacy at risk,” said Chye-Ching Huang, executive director of the nonpartisan Tax Law Center at New York University.

The IRS has not publicly commented on the buyout totals, but internal discussions are reportedly focused on how the agency will maintain operations amid the steep workforce decline.
