IRS Selects Criminal Unit Leader to Oversee Enforcement (1)

The leader of the IRS division that oversees all taxpayer enforcement is getting a new face.

Jarod Koopman will serve as its Acting Chief Tax Compliance Officer, the agency announced Monday. The office has a wide remit, overseeing units in charge of large business and international, small business and self-employed, tax-exempt and government entities, criminal, professional responsibility, return preparers, and whistleblowers.

Edward Killen had been in the role in an acting capacity. Killen will return to his position as the commissioner of the tax-exempt and government entities division.

Koopman is the third person to hold the job this year—one of the many employees stepping into leadership roles amid an exodus of workers who took Trump administration incentives to leave the government, or were pushed out.

Koopman comes from the criminal investigation division and led the creation and development of both the Cyber Crimes and Cyber and Forensics Services sections.

Divisions in the enforcement side of the IRS have come under increased scrutiny under the Trump administration. Republicans in Congress have clawed back tens of billions Democrats gave the agency to beef up enforcement in the 2022 tax-and-climate law.

The chief tax compliance officer is a relatively new position at the agency, created in 2023 in the agency’s first restructuring in decades.
