IRS-CI 2025 report highlights new investigation techniques

The IRS Criminal Investigation division (IRS-CI) has released its Fiscal Year 2025 Annual Report, highlighting a significant escalation in both the scale and sophistication of financial crime enforcement. In FY 2025, IRS-CI identified $10.59 billion in financial crimes, a notable increase from the previous year, with a substantial portion directly related to tax violations. 

Focus on tax fraud

Tax fraud remains a primary focus for IRS-CI. Of the total financial crimes identified, $4.5 billion stemmed from tax fraud, more than doubling the amount from FY 2024. Nearly two-thirds of IRS-CI’s investigative resources were dedicated to tax-related offenses, including refund fraud, employment tax schemes, abusive tax shelters and false claims involving pandemic-related credits.

This renewed emphasis on traditional tax enforcement underscores IRS-CI’s commitment to protecting the integrity of the tax system. For compliant taxpayers, robust enforcement helps ensure fairness and confidence in the system. 

Tip: Due diligence, which includes thorough documentation and conservative reporting, is as important as ever.

Emphasis on digital evidence

IRS-CI’s enforcement efforts are increasingly data-driven. In FY 2025, agents seized 2.35 petabytes of digital data, a nearly 60% increase over the prior year. Cyber-related investigations are on the rise, with average prison sentences in these cases exceeding five years.

Digital assets such as cryptocurrency, online fraud schemes and digital money laundering are now routine elements of IRS-CI investigations. 

Tip: Tax professionals should be aware that digital transactions are highly traceable, and clients should not assume otherwise.

Enforcement in action

The report highlights several high-profile cases, including the Feeding Our Future fraud scheme, one of the largest pandemic-related fraud cases in U.S. history. Defendants received lengthy prison sentences for misappropriating hundreds of millions of dollars intended for low-income children.

Other notable cases involved cryptocurrency laundering, offshore tax evasion and failures by financial institutions to maintain effective anti-money laundering controls. For example, TD Bank pleaded guilty to violations of the Bank Secrecy Act and the money laundering conspiracy, agreeing to pay $1.8 billion in penalties.

These cases demonstrate that financial crimes, whether committed by individuals or institutions, carry significant consequences.

New partnerships and initiatives

IRS-CI is evolving its enforcement approach through new partnerships and initiatives. In FY 2025, the agency launched CI-FIRST, a public-private partnership to improve communication with financial institutions and strengthen Bank Secrecy Act reporting. Another initiative, Optimizing Financial Records Requests, seeks to streamline the process for obtaining and responding to records requests.

These efforts are designed to enhance enforcement efficiency and effectiveness, allowing agents to focus on the most significant threats while reducing administrative burdens.

Implications for tax professionals 

The FY 2025 Annual Report reinforces the importance of compliance for both taxpayers and tax professionals. Strong internal controls, careful client screening and adherence to ethical standards are essential in today’s enforcement environment.

IRS-CI’s work in FY 2025 reflects an agency that is modernizing its tools while remaining committed to its core mission. As financial crimes become more complex, the fundamentals (accurate reporting, honest disclosure and respect for the law) remain the best defense.

Ultimately, the FY 2025 results serve as a reminder that the tax system functions best when all parties comply with the rules. Tax professionals should remain vigilant and proactive in helping clients navigate this evolving landscape.

The FY 2025 results are not just a report card on enforcement. They are reminders that the tax system works best when everyone plays by the rules.
