IRS Criminal Investigation Division

Internal Revenue Service, Criminal Investigation (IRS-CI) investigates potential criminal violations of the U.S. Internal Revenue Code and related financial crimes in a manner intended to foster confidence in the tax system and deter violations of tax law. While other federal agencies also have investigative jurisdiction for money laundering and some bank secrecy act violations, the Internal Revenue Service (IRS) is the only federal agency that can investigate potential criminal violations of the Internal Revenue Code.

Chief Richard Weber oversees a worldwide staff of approximately 3,500 CI employees, including approximately 2,500 special agents who investigate and assist in the prosecution of criminal tax, money laundering, and Bank Secrecy Act related crime cases.

According to statistical data on the IRS web site, Criminal Investigation initiated 4,297 investigations in fiscal year 2014. In addition, the IRS-CI conviction rate (which is the percentage of convictions compared to the total number of convictions, acquittals, and dismissals) was 93.4% in fiscal year 2014.
