The Internal Revenue Service Criminal Investigations (IRS-CI) division identified $10.6 billion in tax and other financial crimes in the federal fiscal year ending September 30, a rise of nearly 16% from the prior year.
In its annual report released Friday, IRS-CI said it found $4.5 billion in tax fraud—an increase of roughly 112%—and more than $6 billion tied to other financial crimes. The agency initiated 1,153 money-laundering cases in fiscal 2025, up from 1,080 new cases in 2024 and a more than 20% rise from the fiscal 2023 total.
The agency also reported a 25% jump in warrants and about a 14% increase in referrals to prosecutors compared with the previous fiscal year.
The IRS attributed the higher totals to shifting priorities, the use of advanced analytics to detect suspicious activity, and a new partnership with financial institutions aimed at identifying potential crimes.
While the report continues to highlight familiar targets such as money laundering, cyber-related crimes and tax credit fraud, it also describes new focus areas tied to administration priorities.
In May, IRS-CI began supporting U.S. Immigration and Customs Enforcement (ICE), including allocating agents to assist in the arrest, detention and deportation of undocumented migrants, according to the report. The report also notes the use of IRS agents to support National Guard deployments in U.S. cities.
