Internal Revenue Service
The IRS is the U.S. government agency responsible for tax collection and tax law enforcement. Outside the United States, IRS Criminal Investigation (IRS-CI) units work with foreign governments to pursue some of the most significant cross border financial investigations targeting tax evasion, fraudulent schemes, organized crime syndicates, narcotics distribution rings and terrorist organizations. In the course of these investigations, the IRS-CI may receive information from informants, assist in undercover operations, gather evidence and financial intelligence, and coordinate regional or global financial investigations with CI field offices.
