The Treasury Department announced on Monday that Social Security Commissioner Frank Bisignano will also serve as the CEO of the Internal Revenue Service (IRS).

Under the move, Treasury Secretary Scott Bessent will remain in the role of acting IRS commissioner while Bisignano will report directly to him from the newly created CEO role.

As the IRS CEO, Bisignano will manage the organization and be responsible for all day-to-day operations at the IRS. He will continue to serve as the Social Security commissioner amid the shakeup.
