U.S. Tax Court

The U.S. Tax Court is a unique federal court dedicated exclusively to resolving disputes over federal tax issues. Established in 1924 originally as the Board of Tax Appeals, it was created to offer taxpayers a less costly and more efficient alternative to traditional courts when contesting Internal Revenue Service (IRS) tax assessments. Unlike other courts, the Tax Court specializes solely in tax laws, which allows its judges, who have extensive expertise in tax codes, to handle cases with precision and fairness.

How the U.S. Tax Court Process Works

If the IRS audits your tax return and determines that you owe additional tax, they will issue a “Notice of Deficiency,” commonly known as a “90-day letter.” This notice gives you 90 days to file a petition with the U.S. Tax Court to dispute the IRS’s claim without paying the disputed tax first. If you miss this deadline, you typically must pay the tax before challenging it in other courts.

Once the petition is filed, the Tax Court schedules hearings where both the taxpayer and IRS present evidence and legal arguments. The court may resolve cases through written decisions or in-person trials depending on the complexity. Judges then issue rulings which can confirm, reduce, or dismiss the IRS’s tax claims.

Types of Cases

• Regular cases: Designed for disputes involving larger amounts or more complex tax issues. These cases follow formal procedures and decisions can be appealed.
• Small cases (S cases): For disputes involving $50,000 or less, these cases offer simplified procedures and faster resolution, but decisions are final with no option to appeal. For details, see our guide on How to Make a Small Case Request in Tax Court.

Who Can Use the U.S. Tax Court?

Individuals, businesses, trusts, and estates who receive a Notice of Deficiency from the IRS can petition the Tax Court. Filing within the 90-day deadline is crucial to preserve the right to dispute a tax claim without prepayment.

Practical Examples

For example, if the IRS claims you underreported $10,000 of income and assesses additional taxes plus penalties, you can contest this through the Tax Court instead of paying upfront. By submitting financial records, receipts, and correspondences, you provide evidence supporting your position. The court may affirm part of the IRS claim, reduce it, or rule fully in your favor, potentially saving you thousands of dollars.

This court is particularly valuable to small business owners who face complex audits or tax disagreements, offering a focused, tax-specialized judicial environment unlike general federal courts.

Tips for Using the U.S. Tax Court

• Monitor Deadlines: The 90-day filing window after receiving a Notice of Deficiency is strict. Missing it forfeits your direct access to the Tax Court.
• Evaluate Small Case Option: If your dispute is under $50,000, consider the Small Case procedure for quicker resolution, but remember decisions are final.
• Prepare Thorough Documentation: Collect all relevant records such as receipts, contracts, and proofs of deductions to support your arguments.
• Consider Settlement: Be open to IRS settlement offers before hearings to save time and litigation costs.
• Seek Professional Support: Navigating Tax Court procedures can be complex. A tax attorney or certified public accountant (CPA) with Tax Court experience can improve the likelihood of a successful outcome. Learn more about Tax Attorneys and how they can help.

Common Misconceptions

• You must pay the disputed tax before contesting it — false. The Tax Court lets you dispute before payment.
• It only handles large tax disputes — incorrect. It also processes small cases under $50,000.
• It operates like other federal courts — no. It uses specialized procedures tailored to tax law.
• You cannot represent yourself — false. Taxpayers can appear pro se, but professional representation is often beneficial.
