Taxpayer Appeals Process: From IRS Appeals Office to Tax Court

Quick overview

The taxpayer appeals process is how taxpayers contest IRS decisions such as audit adjustments, penalty assessments, collection actions, or notices of deficiency. It begins with administrative review by the IRS Office of Appeals, which seeks a fair settlement without litigation, and can end with formal court review in the U.S. Tax Court or federal district courts if you don’t agree with the Appeals outcome (IRS; U.S. Tax Court). (IRS Appeals Office, U.S. Tax Court).

This article explains the steps, common timelines, documentation needs, decisions you can expect, and practical strategies I use in my tax-resolution practice of over 15 years.

How the appeals process works — step by step

1. Initial IRS notice or collection action

• Most appeals start after you receive an IRS notice (audit report, CP/Letter, Notice of Deficiency, or collection notice). Read the notice carefully — it will usually explain your rights and any deadline to respond.

1. Respond promptly and preserve records

• Don’t ignore the notice. Gather the records that support your position (returns, invoices, bank records, contracts, and correspondence). Good recordkeeping makes Appeals and Tax Court filings far easier.

1. Request an administrative appeal

• Administrative appeals are handled by the IRS Office of Appeals. Depending on the notice type, you may request an Appeals conference informally or by following instructions on the notice. Timelines vary by notice type; common deadlines are 30 or 90 days, depending on whether the notice is a collection notice or a Notice of Deficiency (IRS). Always follow the deadline stated on your notice.

1. Pre-appeals or conference with an Appeals officer

• Appeals officers are independent from the exam or collection teams. They review the facts, legal positions, and settlement potential. Many disputes settle at this stage through negotiation, compromise, or technical agreement.

1. Written protest or formal appeal packet

• For certain cases (typically higher-dollar disputes), Appeals requires a written protest that outlines the issues, facts, and legal arguments. Your protest should be organized, include exhibits, and identify the remedies you seek.

1. Appeals decision

• After review and any conference, Appeals issues a decision or settlement offer. If you accept, the case closes per the agreed terms. If you reject the decision, or Appeals denies relief, you may have the right to pursue judicial review.

1. Judicial escalation: U.S. Tax Court or federal courts

• If you received a Notice of Deficiency (a “90-day letter”), you can petition the U.S. Tax Court without paying the disputed tax (you generally have 90 days to file the petition; 150 days if you’re outside the U.S.). If you don’t have a Notice of Deficiency, you may be able to file a refund suit in U.S. district court, but you typically must pay the tax first and then sue for a refund (U.S. Tax Court; IRS). (U.S. Tax Court, IRS Appeals).

Timelines you should know (common examples)

• Notice of Deficiency (90-day letter): 90 days to file a petition with the U.S. Tax Court (150 days if outside the U.S.) (U.S. Tax Court – Filing a Petition).
• Collection Due Process (CDP) notices: typically 30 days to request a CDP hearing using Form 12153 (check your notice for the exact deadline) (IRS Collection Appeal Rights).
• Appeals conferences for audit or examination adjustments: the notice will set the applicable deadline — frequently 30 days for a 30-day letter or other timeframe depending on the specific notice type (always follow the notice instructions).

Note: Deadlines differ by notice and by whether your case involves collection, audit, or a deficiency notice. Review your IRS notice and seek professional guidance if the deadline is unclear.

What issues are appealable?

Most IRS determinations that affect tax liability, penalties, and collection actions are appealable, including:

• Audit adjustments to income, deductions, and credits
• Penalty assessments (e.g., accuracy-related, failure-to-file)
• Collection actions (levies, liens) and proposed seizures
• Denials or rejections of offers in compromise or installment agreements (in some cases)
• Notice of Deficiency situations (which allow direct Tax Court petitions)

The IRS Office of Appeals has broad authority to settle disputes based on hazards-of-litigation analyses and to consider equitable relief in some collection situations (IRS Appeals guidance).

How the U.S. Tax Court fits in

The U.S. Tax Court is the primary judicial forum for prepayment challenges to IRS deficiency notices. Reasons to consider Tax Court:

• You can litigate without paying the disputed tax (when you file within the Notice of Deficiency period).
• Tax Court judges specialize in tax law; informal procedures exist for smaller disputes (Small Tax Case procedure under section 7463 where the amount in controversy is $50,000 or less).

If Appeals doesn’t resolve your dispute, Tax Court gives you a formal trial-like forum with discovery, motions, and a written record. If you lose in Tax Court, you may further appeal to the appropriate U.S. Court of Appeals.

Practical strategies and professional tips (from my practice)

• Start with organized documentation. Create a packet with a timeline, indexed exhibits, and a short summary of your position. Good preparation often wins at Appeals.
• Don’t miss the deadlines. Appeals and Tax Court deadlines are strict and jurisdictional.
• Consider power of attorney. Use Form 2848 if you will have a representative handle negotiations or court filings (IRS Form 2848).
• Learn the difference between administrative relief and judicial relief. Administrative settlement at Appeals is faster and less costly. Court cases create a public record and are lengthier and more expensive.
• Use Appeals’ independence. Appeals officers are separate from the exam or collection teams and focus on resolving disputes equitably. Approach them professionally with clear facts and legal arguments.
• If you have limited time or the amount in dispute is small, consider the U.S. Tax Court Small Case (simplified) procedure for disputes of $50,000 or less. There are tradeoffs: small-case decisions are final but cannot be appealed (U.S. Tax Court guidance).

Common mistakes to avoid

• Waiting too long. Missed deadlines often end your appeal rights.
• Under-documenting your position. Vague assertions without backed evidence rarely succeed.
• Assuming Appeals is adversarial. Appeals seeks fair settlements — a well-prepared, cooperative presentation improves outcomes.
• Skipping representation when risk is high. A knowledgeable tax attorney or CPA can preserve rights and keep your case on track. See our guide on when to hire a pro: When to Hire a Tax Professional for an Audit or Appeal.

Example scenarios (real-world framing)

• Missing 1099 income: If an audit adjustment rests on a missing 1099, document your bank deposits, invoices, and any corrected information returns. Many such cases settle once records are submitted to Appeals.

• Penalty due to reasonable cause: If penalty relief is based on reasonable cause (e.g., natural disaster, serious illness), provide contemporaneous evidence (insurance notices, hospital records). Appeals can grant penalty relief when facts support it.

• Collection due to unpaid tax: If the IRS moves to levy, file for Collection Due Process or request an equivalent hearing quickly; this can delay enforcement while Appeals considers alternatives like an installment agreement or Offer in Compromise.

How to escalate to Tax Court and alternatives

• If you receive a Notice of Deficiency, file a petition in Tax Court within the statutory 90-day (150-day overseas) window to preserve the prepayment right.
• If you already paid the tax, you’ll likely need to sue for refund in U.S. district court or the Court of Federal Claims.
• Consider alternatives like Offers in Compromise, Installment Agreements, or Innocent Spouse relief when appropriate. Appeals often reviews or negotiates those alternatives before litigation.
