IRS Appeals vs U.S. Tax Court
IRS Appeals is an administrative review inside the IRS Independent Office of Appeals. It carries no filing fee, runs informally, and is open at many stages of a case. The U.S. Tax Court is an Article I federal court. After a Notice of Deficiency a taxpayer generally has 90 days to file a petition, or 150 days if the notice is addressed to a person outside the United States, and the court charges a $60 filing fee. Many cases settle in Appeals on either route, and a timely petition preserves the right to a judge. The Law Office of Alexander Powell, PLLC in Washington, DC handles both paths.
Deadlines and fees below were verified against ustaxcourt.gov, uscode.house.gov, and irs.gov on August 19, 2026. The notice in hand controls over this summary.
Side by side
What is the difference between IRS Appeals and U.S. Tax Court?
The rows below compare the two forums on what each body is, which deadline governs, what filing costs, how formal the process runs, who decides, and what follows once both windows close. The Appeals window is the one printed on the IRS letter. The Tax Court window runs from the mailing of the Notice of Deficiency.
| Question | IRS Independent Office of Appeals | U.S. Tax Court |
|---|---|---|
| What it is | An administrative settlement function inside the IRS. The Independent Office of Appeals works apart from the examiners and revenue officers who built the case. | An Article I federal court, independent of the IRS, headquartered in Washington, DC, that hears deficiency and collection cases nationwide. |
| Deadline control | The protest or hearing request window printed on the letter controls. A request made inside that window keeps the administrative path open. | A statutory deadline of 90 days from the Notice of Deficiency, or 150 days if the notice is addressed to a person outside the United States. The Tax Court does not extend it. |
| Cost to file | No filing fee. | A $60 petition filing fee per the court's fee schedule, checked August 19, 2026. |
| Formality and discovery | Informal. Conferences run by telephone or correspondence under Appeals procedures rather than under court rules of discovery and evidence. | Formal litigation. Pleadings, discovery, motions, the rules of evidence, and trial before a judge. |
| Small tax case option | Appeals is administrative. The Small Case Request in Appeals is a separate procedure with its own $25,000 threshold. | Under 26 U.S.C. section 7463, a case may be conducted as a small tax case where the deficiency for any one year is $50,000 or less, or where the unpaid tax in a collection determination appeal is $50,000 or less. The proceedings are informal, and the decision cannot be appealed and sets no precedent. Checked on uscode.house.gov on September 10, 2026. |
| Who decides | An Appeals Officer, who weighs the hazards of litigation and holds authority to settle. | A Tax Court judge, whose decision can be appealed to a federal court of appeals. |
| Once both windows close | The IRS proceeds on its own numbers. The deficiency is assessed and the file moves to collection. | Once the petition window closes, the IRS assesses the tax and collection follows. |

What are the official deadlines and fees?
Under 26 U.S.C. section 6213(a), the taxpayer may petition the Tax Court within 90 days after the Notice of Deficiency is mailed, or 150 days if the notice is addressed to a person outside the United States. The statute counts out Saturday, Sunday, and District of Columbia legal holidays if the last day lands on one. The court charges a $60 petition filing fee under its fee schedule. Both were verified on August 19, 2026. The U.S. Tax Court page sets out the full rule and the printed-date caveat.
Appeals carries no filing fee. A case can reach Appeals after an examination report, after a collection notice that offers hearing rights, or after a Tax Court petition is filed and routed there for settlement. Filing a petition does not commit a taxpayer to a trial. It preserves the right to one while Appeals takes another look, so the petition deadline matters even in cases likely to settle.

Picking between Appeals and Tax Court.
Appeals fits a case where the record supports the taxpayer and the disagreement is about judgment. Documentation the examiner weighed differently, a penalty with a reasonable-cause history, and a valuation question all sit in that category. An Appeals Officer weighs the hazards of litigation and holds authority to settle. The work in Appeals is assembling the record and the argument the officer will weigh.
Tax Court fits when a question of law or a question of credibility needs a judge, and when the petition window is the last step before assessment. A filed petition keeps the case in front of a judge while Appeals works it. Mr. Powell tried more than 75 cases to verdict for the State of Maryland and drafted more than 100 appellate opinions as counsel at the Appellate Court of Maryland. He is admitted in the District of Columbia, Maryland, and before the United States Tax Court, writes and speaks for the American Bar Association Tax Section, and is cited in Law360 Tax Authority for tax controversy analysis. The record is on the About page.
Questions
Common questions about IRS Appeals and Tax Court.
How long do I have to file a Tax Court petition after a Notice of Deficiency?
Generally 90 days from the date the IRS mails the Notice of Deficiency, or 150 days if the notice is addressed to a person outside the United States, under 26 U.S.C. section 6213(a), checked September 10, 2026. The Tax Court does not grant extensions, and the statute counts out Saturdays, Sundays, and District of Columbia legal holidays. Two qualifications matter. Filing by the last date the IRS prints on the notice is treated as timely even if that date falls later than 90 days. And after Boechler v. Commissioner in 2022, several courts of appeals have held that a late petition can be equitably tolled in narrow circumstances, and the courts are split. The date printed on the notice controls.
How much does it cost to file in U.S. Tax Court?
The court charges a $60 petition filing fee under its fee schedule, checked August 19, 2026. That amount is paid to the court rather than to the IRS, and it covers the filing itself. Professional fees for representation are separate and are quoted by whoever the taxpayer hires. The court may waive the filing fee when a petitioner shows an inability to pay. IRS Appeals charges no filing fee for a conference.
Does IRS Appeals charge a fee?
No. The IRS Independent Office of Appeals charges no filing fee and no user fee for a conference. A case reaches Appeals on a written protest or a hearing request, and the window for that request is printed on the IRS letter. The cost of an Appeals case is the professional fee for any representative and the time the record takes to prepare. The IRS Appeals page is linked in the official sources above.
Can I go to IRS Appeals and then to Tax Court?
In the usual sequence Appeals comes first or runs alongside the court case. Many Tax Court petitions are routed to Appeals for settlement talks after filing, and many cases settle there without a trial. The petition period keeps running during settlement discussions, so the date printed on the notice still governs. Filing on time preserves the right to a judge while Appeals works the case.
What happens if I ignore a Notice of Deficiency?
The IRS assesses the proposed deficiency once the petition window closes, and the file moves from examination to collection. From there the dispute shifts from whether the amount is right to how it will be collected through liens, levies, and payment arrangements. The routes that remain after assessment, such as audit reconsideration or a refund claim, are narrower than a timely petition and carry requirements of their own.
Who may appear in IRS Appeals or Tax Court?
A taxpayer may appear in either forum without a lawyer, and CPAs and enrolled agents may represent a taxpayer in Appeals. Representation in the Tax Court requires admission to that court under Tax Court Rule 200. Tax Court admission is a separate credential from a CPA or enrolled agent license. Attorneys are admitted on motion, and a small number of nonattorneys are admitted by examination. Mr. Powell is admitted to the United States Tax Court and handles matters in both forums.
If the letter is already in hand.
Use IRS Letter Check when the paper is a supported federal notice. Letter 3219 explains the Notice of Deficiency in plain language. The Appeals hub and the Tax Court hub map both paths from the Washington, DC office. If the notice shows a response date, that date controls over anything on this page.
