Internal Revenue Service (IRS) Commissioner Danny Werfel on Friday announced he will resign his post on Monday, the same day as President-elect Donald Trump's inauguration.

Trump nominated former Missouri Rep. Billy Long to replace Werfel last month, but the current commissioner still has several years left in his five year term. But Werfel’s deputy, Doug O’Donnell, will run the agency until Long is confirmed by the Senate.

Werfel's decision comes ahead of the 2025 tax season, which is set to begin on January 27. The agency was also in the middle of a major overhaul that made it easier for filers to contact the IRS via phone, according to Politico.

“After significant introspection and consultation with others, I’ve determined the best way to support a successful transition is to depart the IRS on January 20, 2025,” Werfel told agency employees. “We have delivered two of the best filing seasons in decades, with significantly improved phone, online and in-person service ... We answered nearly nine in 10 calls the last two filing seasons, up from fewer than two in 10 calls, while cutting call wait times from 30 minutes to under five minutes.”

Other officials have also announced they will resign on Inauguration Day, including FBI Director Christopher Wray, Securities and Exchange Commission Chair Gary Gensler, and Federal Election Commission head Sean Cooksey.

Long, who is in line to testify in front of the Senate Finance Committee after they confirm other top officials like Treasury Secretary nominee Scott Bessent, will serve the rest of Werfel's term if confirmed, which ends Nov. 12, 2027.
