The Department of the Treasury's Office of Inspector General (OIG) was established pursuant to the 1988 amendments to the Inspector General Act of 1978. OIG is headed by an Inspector General appointed by the President, with the advice and consent of the Senate. Serving with the Inspector General in the immediate office is a Deputy Inspector General. OIG performs independent, objective reviews of Treasury programs and operations, except for those of the Internal Revenue Service (IRS) and the Troubled Asset Relief Program (TARP), and keeps the Secretary of the Treasury and Congress fully informed of problems, deficiencies, and the need for corrective action. The Treasury Inspector General for Tax Administration performs oversight related to IRS. A Special Inspector General and the Government Accountability Office perform oversight related to TARP.
