Most taxpayers who receive an unfavorable IRS examination result assume their only options are to pay the assessment or hire a lawyer and go to Tax Court. In reality, there is a third path that resolves the majority of tax disputes: the IRS Independent Office of Appeals.

Appeals is a separate, independent function within the IRS. Its mission is to resolve tax controversies without litigation, on a basis that is fair and impartial to both the government and the taxpayer. It is not a rubber stamp for the examination division — Appeals officers have authority to settle cases based on the hazards of litigation, and they frequently do.

Understanding your appeals rights, the deadlines that govern them, and how to present a case effectively can mean the difference between a resolved dispute and an unnecessary Tax Court proceeding.

The right to appeal an IRS determination is grounded in the Internal Revenue Code and IRS administrative procedures.

• IRC §7803(e) establishes the IRS Independent Office of Appeals and requires that it be independent of IRS compliance functions.
• IRC §7123 provides for alternative dispute resolution procedures within Appeals.
• Rev. Proc. 2012-18 governs ex parte communications between Appeals and other IRS functions.
• IRM 8.1 governs Appeals procedures generally.

The Taxpayer First Act of 2019 (Pub. L. 116-25) codified the independence of the Appeals function and expanded taxpayer access to Appeals in certain collection cases.

Appeals rights arise at several points in the IRS examination and collection process.

When an IRS examination concludes with proposed adjustments, the IRS issues a 30-day letter (Letter 525 or Letter 915) along with the examination report (Form 4549). The 30-day letter gives the taxpayer 30 days to:

1. Accept the proposed adjustments and sign Form 870;
2. Request a conference with the examining agent's supervisor; or
3. File a written protest requesting Appeals consideration.

If the taxpayer does not respond within 30 days, the IRS will issue a statutory notice of deficiency (90-day letter), which triggers a separate set of rights.

If the taxpayer does not resolve the dispute at the examination level, the IRS issues a Notice of Deficiency under IRC §6212. This is a critical document:

• The taxpayer has 90 days (150 days if addressed outside the United States) to file a petition with the U.S. Tax Court.
• During this 90-day period, the IRS cannot assess the deficiency.
• If the taxpayer does not file a Tax Court petition within 90 days, the IRS assesses the deficiency and collection begins.

A taxpayer who receives a Notice of Deficiency and wants to pursue Appeals — rather than Tax Court — should file the Tax Court petition to preserve rights, then request that the case be referred to Appeals for settlement consideration. Most Tax Court cases are settled through Appeals before trial.

When the IRS issues a Notice of Federal Tax Lien or a Notice of Intent to Levy, the taxpayer has the right to request a Collection Due Process (CDP) hearing with Appeals under IRC §§6320 and 6330.

The CDP hearing must be requested within 30 days of the lien notice or 30 days of the levy notice. At the CDP hearing, the taxpayer may:

• Challenge the appropriateness of the collection action;
• Propose collection alternatives (installment agreement, offer in compromise, currently not collectible status);
• Raise spousal defenses; and
• Challenge the underlying liability if the taxpayer did not previously have an opportunity to do so.

A CDP determination by Appeals is appealable to Tax Court.

A taxpayer who misses the 30-day CDP deadline may request an equivalent hearing within one year of the lien or levy notice. Equivalent hearings provide the same substantive review as CDP hearings but do not suspend collection and are not appealable to Tax Court.

For cases involving $25,000 or less per tax year, the taxpayer may submit a small case request — an informal written statement explaining the disagreement. No formal protest is required.

For cases involving more than $25,000 per tax year, the taxpayer must submit a formal written protest that includes:

1. The taxpayer's name, address, and identification number;
2. A statement that the taxpayer wants to appeal the IRS findings;
3. The date and symbols from the 30-day letter;
4. The tax years or periods involved;
5. An itemized schedule of the adjustments being disputed;
6. A statement of facts supporting the taxpayer's position for each disputed item; and
7. A statement of law or other authority supporting the taxpayer's position.

The protest must be signed under penalties of perjury.

Appeals officers are experienced IRS employees who review the examination file, the taxpayer's protest, and applicable law. They are authorized to settle cases based on the hazards of litigation — meaning they can accept less than the full amount the examination division proposed if there is a reasonable chance the IRS would lose in court.

The Appeals process typically involves:

1. Case assignment — the case is assigned to an Appeals officer at the appropriate campus or field office;
2. Pre-conference preparation — the taxpayer or representative reviews the examination file and prepares a position paper;
3. Appeals conference — a meeting (in person, by telephone, or by correspondence) where the taxpayer presents arguments and documentation;
4. Settlement negotiation — the Appeals officer may propose a settlement based on the merits and litigation hazards; and
5. Closing agreement or assessment — if settlement is reached, the parties execute a closing document; if not, the case proceeds to Tax Court or the taxpayer pays the assessment.

Appeals is a settlement forum. The goal is resolution, not adjudication. Taxpayers who present well-organized, legally supported positions generally achieve better outcomes than those who simply repeat the arguments made during examination.

The IRS offers alternative dispute resolution programs that can resolve disputes more quickly than traditional Appeals.

Fast Track Settlement (FTS) — available for cases still in examination — allows a taxpayer and the examining agent to jointly request Appeals involvement to facilitate settlement while the case is still open. FTS can resolve disputes in 60 days or less.

Fast Track Mediation (FTM) — available for collection cases and certain other matters — uses an Appeals mediator to facilitate resolution between the taxpayer and the IRS collection function.

Post-Appeals Mediation (PAM) — available after a traditional Appeals conference fails to produce settlement — provides a final opportunity for mediated resolution before Tax Court.

If Appeals does not resolve the dispute, the taxpayer has several judicial options depending on the procedural posture:

Most taxpayers prefer Tax Court because it does not require prepayment of the disputed tax. The Tax Court has a Small Tax Case (S Case) procedure for disputes of $50,000 or less per year, which is less formal and less expensive than regular Tax Court proceedings.

Never ignore a 30-day letter. The 30-day deadline is not a hard statutory deadline — the IRS will still issue a Notice of Deficiency if you miss it — but responding promptly preserves your right to a pre-assessment Appeals conference, which is generally more favorable than post-assessment proceedings.

Organize your documentation before the conference. Appeals officers review hundreds of cases. A well-organized presentation with clear legal arguments and supporting documentation is far more persuasive than an oral argument without backup.

Know the difference between facts and law. Appeals officers can settle factual disputes based on litigation hazards. They have less flexibility on pure legal issues where the IRS's position is well-established. Identifying which issues are factual and which are legal helps focus the settlement discussion.

Consider professional representation. Appeals conferences involve legal arguments, procedural rules, and negotiation strategy. An Enrolled Agent, CPA, or tax attorney with Appeals experience can substantially improve the outcome.

The IRS Independent Office of Appeals is one of the most valuable — and underused — resources available to taxpayers facing an IRS examination result. It provides a formal, non-judicial forum to resolve disputes based on the merits, without the cost and uncertainty of Tax Court litigation.
