We fulfill our mission by using advanced data-driven investigative techniques; coordinating with agencies responsible for administering taxpayer-funded programs; partnering with federal, tribal, state, territorial, and local law enforcement on fraud-fighting efforts; developing systems and processes that ensure efficient identification and investigation of fraud; and equipping prosecutors and law enforcement with state-of-the-art tools and resources needed to bring criminal actors to justice. Our cases involve traditional violations of criminal tax laws by taxpayers having legal sources of income, including, for example, tax evasion and the filing of false tax returns, as well as cases involving fraudulent claims against the public fisc for refunds, tax defiers, identity theft, financial institution fraud, securities fraud, health care fraud, organized crime activities, and narcotics trafficking.
