U.S. Tax Court

The United States Tax Court is a federal trial court of record established by Congress under Article I of the U.S. Constitution, section 8 of which provides (in part) that the Congress has the power to "constitute Tribunals inferior to the supreme Court". The Tax Court specializes in adjudicating disputes over federal income tax, generally prior to the time at which formal tax assessments are made by the Internal Revenue Service. Though taxpayers may choose to litigate tax matters in a variety of legal settings, outside of bankruptcy, the Tax Court is the only forum in which taxpayers may do so without having first paid the disputed tax in full. Parties who contest the imposition of a tax may also bring an action in any United States District Court, or in the United States Court of Federal Claims; however these venues require that the tax be paid first, and that the party then file a lawsuit to recover the contested amount paid (the "full payment rule" of Flora v. United States). Tax Court judges are appointed for a term of 15 years, subject to presidential removal for "inefficiency, neglect of duty, or malfeasance in office...."

The first incarnation of the Tax Court was the "U.S. Board of Tax Appeals", established by Congress in the Revenue Act of 1924 (also known as the Mellon tax bill) in order to address the increasing complexity of tax-related litigation. Those serving on the Board were simply designated as "members." The members of the Board were empowered to select, on a biennial basis, one of their members as "chairman." The Board originally had 16 members, with Charles D. Hamel serving as the first Chairman. The Board was initially established as an "independent agency in the executive branch of the government." It was housed in the Internal Revenue Service Building in the Federal Triangle. The first session of the Board of Tax Appeals spanned July 16, 1924 to May 31, 1925.
