Treasury Secretary Scott Bessent is tapping Social Security Administration Commissioner Frank Bisignano to serve as the chief executive officer of the Internal Revenue Service, a new position at an agency that has undergone multiple leadership shakeups this year.

Bisignano will continue to lead the SSA while managing day-to-day operations at the IRS. Bessent, who has served as acting IRS Commissioner since August, will continue in the top role at the tax agency.

“Under his leadership at the SSA, he has already made important and substantial progress, and we are pleased that he will bring this expertise to the IRS as we sharpen our focus on collections, privacy, and customer service in order to deliver better outcomes for hardworking Americans,” Bessent said in a statement Monday.

The newly created CEO position at the IRS, does not require Senate confirmation, unlike the IRS commissioner job. Seven people have served as IRS commissioner in 2025 alone, according to the agency’s website. The most recent Senate-confirmed commissioner was Billy Long, a former member of Congress and ally of President Donald Trump, who left the agency in August after fewer than two months on the job. 

The move to give Bisignano a second full-time job has become commonplace in Trump’s second term. He has given several top officials additional roles as he seeks to quickly fill high-profile positions with loyalists. Secretary of State Marco Rubio, Budget Director Russell Vought and US envoy Ric Grenell all hold multiple titles.

Bisignano now will oversee two sprawling bureaucracies. The Social Security Administration, which employs more than 50,000 people, is responsible for distributing billions of dollars in benefits each month, including $131 billion in August alone, to more than 70 million people. 

The IRS adds an additional 74,000 employees to Bisignano’s portfolio. He assumes the new CEO role at a crucial time for the agency, as it works with Treasury to implement Trump’s new tax law, which created a slew of new tax breaks for the next filing season, including exemptions for tips and overtime income. The tax changes are a large administrative lift for the agency, requiring it to create new tax forms.

Before taking over the Social Security Administration in May, Bisignano served as CEO of Fiserv Inc., which provides payment processing and other digital services to the financial institutions.
