Latest Highlights from the IRS-CI

bigstock-Handcuffs-A-Criminal-Fingerpr-326501557The Internal Revenue Service (IRS) has many departments, one of them being the Criminal Investigation (CI) unit. This department serves the U.S. by investigating criminal financial crimes such as tax fraud, money laundering, identity theft scams, healthcare fraud and more.


You can learn about IRS-CI's processes and latest cases on their website, but we wanted to share some highlights of theirs from the past several years that they recently shared with us:

Below is just a small example of the types of cases in which CI has led or been significantly involved in over the last few years. These cases show the breadth and skill of CI’s Special Agents in various types of fraud and criminal activity that have had significant impacts on the financial system at home and abroad. Despite having 25% less staff over the course of the decade, CI has consistently delivered strong results. An increase in funding would help to add more investigations to the pipeline, ensure more criminals are held accountable, and shore up the global financial system.

Narcotics/Counterterrorism/National Security Investigations

IRS:CI targets the illicit financial flows of Transnational Criminal Organizations to reduce the economic incentive of narcotics trafficking, terrorist financing, and money laundering. IRS:CI has key positions to enhance operational coordination at DEA SOD, EO-OCDETF, OCDETF Fusion Center, FinCEN, IOC2, HIDTA, J-CODE in addition to Joint Terrorism Task Force (JTTF) and National Counterintelligence Task Force (NCITF). Investigations involve money laundering (Title 18) and currency violations (Title 31). IRS:CI is the largest user of Bank Secrecy Act data to identify significant financial criminal activity. Investigative areas include: money laundering, narcotics, public corruption, corporate fraud, terrorism, healthcare fraud, and financial institution fraud.
