There are roughly 20,000 employees of the IRS who have expressed interest in leaving the tax enforcement agency by using a deferred resignation program from President Donald Trump.

IRS leadership under Trump aims to downsize the force of slightly more than 102,000 with the deferred resignation offer and waves of mass layoffs. The resignation deal lets employees remain on payroll through the end of September while they are on administrative leave.

The employees were provided a deadline of April 14 to accept the deferred resignation offer. One internal email said they are allowed to leave their positions at the IRS as soon as April 28.

Other efforts to downsize the IRS, which had their staff rosters expanded under legislation signed by former President Joe Biden, include offering a previous deferred resignation which 4,700 employees took and placing 7,300 probationary employees on administrative leave.

Trump administration officials will meanwhile send waves of reduction in force notices to dismiss employees at the IRS, with the ultimate goal of having between 60,000 and 70,000 staffers.

One spokesperson for the Treasury Department told the media that they are “committed to ensuring that efficiency is realized while providing the collections, privacy, and customer service the American people deserve.” The statement added that the cuts will enable the “consolidation of critical support functions” that are “vital to improve both efficiency and quality of service.”
