About TIGTA

The Treasury Inspector General for Tax Administration (TIGTA) was established in January 1999 by the Internal Revenue Service (IRS) Restructuring and Reform Act of 1998 to provide independent oversight of IRS activities.

We provide high-quality audit, investigative, and evaluation services to promote integrity, efficiency, and economy in the administration of the nation’s tax system. Although we are placed organizationally within the Department of the Treasury and report to the Secretary of the Treasury and to Congress, we function independently from all other offices and bureaus within the Department of the Treasury.

TIGTA is committed to serving the public by conducting audits and investigations that improve IRS operations. TIGTA's audit and investigative activities are designed to:

  • Investigate IRS employee misconduct and external attempts to corrupt or threaten IRS employees.
  • Provide policy direction and conduct, supervise, and coordinate audits and investigations related to IRS programs and operations.
  • Review and make recommendations on existing and proposed legislation and regulations related to IRS programs and operations.
  • Promote economy and efficiency in the administration of tax laws.
  • Prevent and detect waste, fraud, and abuse in IRS programs and operations.
  • Inform the Secretary of the Treasury and Congress of problems and deficiencies identified and of the progress made in resolving them.
