IRS Appeals Process — Complete Guide

Executive Summary for Practitioners

The IRS Independent Office of Appeals ("Appeals") serves as the primary administrative forum for resolving tax disputes without litigation. Established under the Taxpayer First Act of 2019 and codified in IRC § 7803(e), Appeals is independent of the IRS Examination and Collection functions. Its mission is to resolve tax controversies on a basis which is fair and impartial to both the Government and the taxpayer and in a manner that will enhance voluntary compliance and public confidence in the integrity and efficiency of the Service.

For practitioners, the Appeals process is a critical tool for achieving settlements based on the "hazards of litigation." Unlike Revenue Agents, Appeals Officers have the authority to settle cases by considering the probability that the IRS might lose in court. This authority is unique to Appeals and allows for pragmatic resolutions that avoid the time and expense of Tax Court litigation.

IRC Authority and Regulatory Framework

The legal basis for the IRS Appeals process is rooted in several sections of the Internal Revenue Code and Treasury Regulations:

• IRC § 7803(e): Establishes the Internal Revenue Service Independent Office of Appeals.
• IRC § 6320 & § 6330: Provide the statutory basis for Collection Due Process (CDP) hearings related to liens and levies.
• Treas. Reg. § 601.106: Outlines the general procedures for Appeals functions.
• Revenue Procedure 2026-1: Provides updated procedural rules for requesting letter rulings and determination letters, which often intersect with the appeals process.

2026 Tax Figures and Thresholds

All practitioners must ensure that any settlement discussions or calculations involving 2026 tax years utilize the following verified figures:

Detailed Implementation Guide: Requesting an Appeal

Navigating the Appeals process requires strict adherence to procedural timelines and documentation requirements. Failure to follow these steps can result in the loss of appeal rights or unnecessary delays.

Step 1: Analyze the Preliminary Determination

Upon receipt of a 30-day letter (Examination) or a Notice of Intent to Levy (Collection), review the IRS's findings. Determine if the disagreement is based on a factual dispute, a legal interpretation, or both. Practitioners should conduct a thorough "hazards of litigation" analysis at this stage to determine the viability of an appeal.

Step 2: Determine the Correct Appeal Path

Choosing the right path is critical for preserving judicial review rights:

• Formal Written Protest: Required for most examination cases where the total amount of tax, penalties, and interest exceeds $25,000.
• Small Case Request: Available for examination cases where the total amount is $25,000 or less. Use Form 12203.
• Collection Due Process (CDP): Use Form 12153 to request a hearing under IRC § 6320 or § 6330. This path offers judicial review rights in Tax Court.
• Collection Appeals Program (CAP): Use Form 9423 for a faster but more limited appeal of specific collection actions (liens, levies, seizures). Note: CAP decisions are binding and do not offer Tax Court review.

Step 3: Draft the Formal Protest

A formal protest must be comprehensive and professional. It must include:

1. Taxpayer's name, address, and SSN/EIN.
2. A statement that the taxpayer wants to appeal the findings to the Independent Office of Appeals.
3. A copy of the letter showing the proposed changes.
4. The tax periods or years involved.
5. An itemized schedule of the adjustments with which the taxpayer does not agree.
6. A statement of facts supporting the taxpayer’s position on any contested factual issue.
7. A statement outlining the law or other authority upon which the taxpayer relies.
8. A declaration under penalties of perjury.

Step 4: Submission and Initial Review

Mail the protest to the address indicated on the IRS letter. The originating office (Examination or Collection) will first review the protest. They may concede some issues or request additional information before forwarding the file to Appeals. This is often referred to as the "pre-Appeals" review phase.

State Applicability and Specific Considerations

Most states have their own tax appeals processes that mirror the IRS but have distinct procedural nuances. Practitioners must be aware of these differences to provide comprehensive advice.

Common Mistakes and Audit Triggers

Avoiding common pitfalls is essential for a successful appeal. Practitioners should be mindful of the following:

• Missing the 30-Day Deadline: Unlike the 90-day letter (Notice of Deficiency), the 30-day deadline for a protest is not statutory but is strictly enforced by IRS policy. Missing this deadline often forces the taxpayer into a "pay first, sue later" position.
• Incomplete Protests: Failing to cite specific IRC sections or Treasury Regulations often results in the protest being returned for "perfection," delaying the case and potentially frustrating the Appeals Officer.
• New Issues in Appeals: While Appeals can consider new evidence, raising entirely new issues not discussed during the audit can cause the case to be remanded back to Examination, effectively restarting the audit process.
• Audit Triggers for 2026: High-ratio business expenses relative to gross income, consistent Schedule C losses (IRC § 183 "Hobby Loss" rules), and large non-cash charitable contributions remain top triggers for 2026 audits.

Advanced Settlement Strategies: The Hazards of Litigation Analysis

The "hazards of litigation" standard is the cornerstone of the Appeals process. Unlike a Revenue Agent, who is generally bound by the IRS's interpretation of the law, an Appeals Officer must evaluate how a court would likely rule on a given issue. This evaluation is not a simple "win or lose" calculation but a nuanced assessment of several factors:

• Strength of Factual Evidence: Does the taxpayer have credible testimony, third-party documentation, or reconstructed records that would be admissible in court?
• Clarity of Legal Authority: Is the issue governed by a clear IRC section, or is it subject to conflicting interpretations in different judicial circuits?
• Credibility of Witnesses: How would the taxpayer or other key witnesses perform under cross-examination in a trial setting?
• IRS Litigation Policy: Does the IRS have a "litigation position" on the issue, or is it an area where the Service is willing to concede for the sake of administrative efficiency?

Practitioners should present their hazards of litigation analysis in a structured format, often using a "weighted average" approach to propose a settlement. For example, if a legal issue has a 40% chance of being decided in the taxpayer's favor, a settlement offer of 60% of the tax might be appropriate.

The Role of the Taxpayer Advocate Service (TAS) in Appeals

While Appeals is independent, taxpayers sometimes encounter systemic delays or procedural hurdles that prevent a fair hearing. In such cases, the Taxpayer Advocate Service (TAS) can intervene. Under IRC § 7803(c), TAS is an independent organization within the IRS that helps taxpayers resolve problems with the IRS and ensures that taxpayers are treated fairly and know their rights.

If an Appeals case is stalled for an unreasonable amount of time, or if the IRS is taking collection action while an appeal is pending (in violation of CDP rules), a practitioner can file Form 911, Request for Taxpayer Advocate Service Assistance. TAS can issue a Taxpayer Assistance Order (TAO) to compel the IRS to take specific actions, such as releasing a levy or expediting an appeals conference.

Post-Appeals Options: What Happens if No Agreement is Reached?

If the taxpayer and the Appeals Officer cannot reach a settlement, the IRS will issue a formal notice that concludes the administrative process. The type of notice depends on the nature of the dispute:

• Statutory Notice of Deficiency (90-Day Letter): Issued at the end of an audit appeal. The taxpayer has 90 days (150 days if outside the U.S.) to file a petition with the U.S. Tax Court. This is a "pre-payment" forum, meaning the tax does not have to be paid before the court hears the case.
• Notice of Determination: Issued at the end of a CDP hearing. The taxpayer has 30 days to file a petition with the Tax Court.
• Notice of Claim Disallowance: Issued if the appeal involved a refund claim. The taxpayer generally has two years to file a refund suit in a U.S. District Court or the U.S. Court of Federal Claims. This is a "post-payment" forum.

Specialized Appeals Programs

Beyond standard audit and collection appeals, the Office of Appeals handles several specialized programs designed to resolve specific types of disputes:

• Fast Track Settlement (FTS): Available for large business and international (LB&I) and small business/self-employed (SB/SE) taxpayers. FTS allows an Appeals Officer to act as a mediator while the case is still in the Examination phase, often resolving disputes in 60 days or less.
• Post-Appeals Mediation (PAM): If an agreement is not reached in Appeals, the taxpayer may request mediation. A different Appeals Officer or a non-IRS mediator helps the parties reach a settlement. This is generally available for factual issues and certain legal issues.
• Early Referral to Appeals: Under Revenue Procedure 99-28, a taxpayer can request that specific unagreed issues be referred to Appeals while the rest of the audit continues in Examination. This is useful for resolving "gatekeeper" issues that affect the rest of the audit.

The Impact of the Taxpayer First Act on Appeals

The Taxpayer First Act of 2019 (TFA) significantly strengthened the independence of the Office of Appeals. Key provisions include:

• Statutory Independence: Codified the "Independent Office of Appeals" to ensure it remains separate from other IRS functions.
• Access to Case Files: For most taxpayers, the TFA requires the IRS to provide access to the non-privileged portions of the case file before the appeals conference. This allows practitioners to see exactly what evidence the Revenue Agent relied upon.
• Notice of Rejection: If the IRS denies a request for an appeal, they must provide a written explanation for the denial and outline the taxpayer's rights to protest that denial.

Practitioner Best Practices for Appeals Conferences

A successful appeals conference requires more than just technical knowledge; it requires effective negotiation skills. Practitioners should follow these best practices:

1. Prepare a "Conference Memorandum": Even if a formal protest was filed, a concise 2-3 page memo summarizing the key issues and the proposed settlement can help focus the discussion.
2. Be Professional and Cooperative: Appeals Officers have significant discretion. A professional, non-adversarial tone can go a long way in achieving a favorable settlement.
3. Focus on the Hazards: Don't just repeat the arguments made to the auditor. Focus on why the IRS might lose in court. Cite specific cases where the IRS lost on similar facts.
4. Know Your Bottom Line: Before the conference, discuss with the client the maximum amount they are willing to pay. This allows you to negotiate with confidence.
5. Follow Up in Writing: After the conference, send a brief email or letter summarizing any agreements reached and any additional information you promised to provide.
