The Taxpayer Advocate Service and the IRS
Occasionally, the U.S. Congress discovers to its great surprise that the agency it created to collect revenues for the federal government, the Internal Revenue Service, engages in systematic abuse of taxpayers. In one such moment in 1979, Congress created the Office of the Taxpayer Ombudsman as a taxpayer advocate within the IRS. This office eventually became the Taxpayer Advocate Service (TAS). by authority of first so-called "Taxpayer Bill of Rights" in 1988.
