About Criminal Investigation

 

The American system of taxation is based on the premise that all income is taxable (which includes illegally earned income). In many instances, proving that a taxpayer willfully attempted to hide income from the Federal Government is an integral part of proving other criminal activity including fraud, money laundering or Bank Secrecy Act violations. Criminal Investigation continues to fulfill the important role of helping to ensure the integrity and fairness of our nations' tax system.

IRS-CI is the criminal investigative arm of the IRS, responsible for conducting financial crime investigations, including tax fraud, narcotics trafficking, money-laundering, public corruption, healthcare fraud, identity theft and more. IRS-CI special agents are the only federal law enforcement agents with investigative jurisdiction over violations of the Internal Revenue Code, obtaining a more than a 90 percent federal conviction rate. The agency has 20 field offices located across the U.S. and 12 attaché posts abroad.

Initiating an investigation

IRS special agents must follow strict procedures to initiate an investigation and recommend prosecution to the Department of Justice. These procedures include approval by several IRS officials to ensure investigations are based on factual evidence that tax fraud or another financial crime has occurred.
