The U.S. Tax Court is a specialized federal court dedicated to resolving disputes between taxpayers and the Internal Revenue Service (IRS) regarding federal income, estate, and gift taxes. Unlike other courts, it allows taxpayers to challenge IRS determinations without having to pay the contested tax amount upfront.

Role and Jurisdiction

Established by Congress in 1924, the Tax Court offers a judicial forum for taxpayers to dispute IRS findings before paying any tax liability. This pre-payment advantage distinguishes it from district courts and the Court of Federal Claims, where tax disputes typically require payment first.

The court primarily hears cases involving:

  • Tax deficiencies (disputes over IRS audits or assessments)
  • Penalties imposed by the IRS
  • Disputes related to deductions, credits, and income reporting
  • Certain procedural issues related to federal tax laws

Taxpayers generally must timely file a petition with the U.S. Tax Court within 90 days after receiving a “Notice of Deficiency” (commonly known as a “90-day letter”) from the IRS. This notice informs the taxpayer of proposed tax adjustments and their right to petition the court.

Procedures and Rules

The U.S. Tax Court operates under its own Rules of Practice and Procedure, which govern filing petitions, discovery, trials, and appeals. These rules are designed to facilitate fair and efficient case resolution.

Most cases are decided based on written evidence and briefs without in-person hearings, though trials may be held in Washington, D.C., or other locations nationwide. The court’s proceedings are generally less formal and less costly than federal district courts.

Appeals Process

If unsatisfied with the U.S. Tax Court decision, taxpayers may appeal to the appropriate U.S. Court of Appeals. Decisions from the Tax Court set important precedents on federal tax law.

How to Prepare and What to Expect

Taxpayers involved in disputes that could reach the Tax Court should familiarize themselves with IRS Publication 5, “Your Appeal Rights and How To Prepare a Protest If You Don’t Agree With the IRS,” which offers guidance on the appeals process and preparing formal protests or petitions.

Understanding when and how to petition the court, along with its rules and procedures, can significantly impact the outcome of tax disputes and protect taxpayer rights.
