The United States Tax Court is established under Article 1 of the United States Constitution and exists to resolve disputes between taxpayers and the Internal Revenue Service. The U.S. Tax Courts website has several helpful resources about the Tax Court System that include the following:
This website can also be used to find the forms, opinions, and orders of the Tax Court.
Other than being focused on tax law, there are a couple qualities about the Tax Court that are different from other courts:
The United States Tax Court has their own Rules of Practice and Procedure. To view the historical explanations of the Rules, you can access the Guide to Rules Amendments and Notes.
In addition to the Tax Court rules freely available on the United States Tax Courts website, you can also access helpful Annotated Versions of the Rules of Practice and Procedure on Bloomberg Law, Lexis+, and Westlaw. The Law Library has limited holdings of these rules available in print. [ KF6324.A39 T39]. The most recent print version the Law Library holds is from 2003.
Petitions and complaints in the U.S. Tax Court are the equivalent of records and briefs for other courts. You can find petitions, complaints, and dockets online using Bloomberg.
The first place of recourse is in the U.S. Tax Court, which is a specialized Article I court that handles only tax cases. Decisions made in this court are appealed to the U.S. Court of Appeals. There are 3 kinds of decisions that the U.S. Tax Court can issue:
More about these decisions and where to find them is below.
The second place of recourse for taxpayers is to bring their suits in the U.S. Claims Courts. This specific court is where taxpayers can dispute assessments of tax liability and file for refunds. If their request for a refund is rejected, then they can file a suit for their refund in this court. Decisions made in this court are appealed to the U.S. Court of Appeals for the Federal Circuit.
Memorandum decisions are the most common type of case heard in the U.S. Tax Courts. These decisions are those where a taxpayer's situation is disputed, but it is most commonly not a decision that involves an interpretation of the Internal Revenue Code. These cases are not officially reported, but because there are so many of them, they carry slightly more weight than Small Cases Division Decisions.

The Law Library has print holdings of these decisions from 1946 on, and the electronic holdings have availability from 1942 on.
