The IRS has undertaken significant workforce reductions, cutting about 50 IT executives as part of a strategy to enhance compliance with immigration enforcement data-sharing regulations. The agency has sidelined dozens of top IT officials seen as potential obstacles to these changes, putting many on leave. In a related development, the Treasury Department has elevated Jeffrey King from deputy CIO to Acting CIO, positioning him to lead the IT department during this transition. These moves come as the IRS faces legal challenges from unions regarding job cuts tied to labor orders initiated during previous administrations.
