Should You Agree With the IRS Audit Findings or Appeal?

Where you are when you have to decide

The agree-or-appeal decision usually arrives with a 30-day letter. IRS Publication 3498 (Rev. 5-2025) says that if you and the examiner don’t reach agreement, “you will receive a letter (known as a 30-day letter) letting you know of your right to appeal the proposed changes,” and you “generally have 30 days from the date of the letter” to accept them or appeal. It comes with the examination report listing each proposed change. Our page on the IRS 30-day letter walks through the letter itself.

You have more than two options:

• Agree with all the changes and sign the agreement form.
• Agree in part: settle the items you accept and dispute the rest.
• Talk to the examiner’s manager. Publication 5 says that if you can’t agree with the examiner, you can generally ask to discuss it with the examiner’s supervisor.
• Ask for Fast Track Settlement if your case qualifies (see below).
• Appeal to the IRS Independent Office of Appeals with a small case request or a formal written protest.
• Skip Appeals and wait for the notice of deficiency, then petition the U.S. Tax Court.

If you do nothing, Publication 3498 says the IRS “will send you a 90-day letter, also known as a notice of deficiency.” That notice starts the Tax Court deadline described in our guide to the notice of deficiency (the CP3219A is one version). A CP2000 is different: it is an automated income-matching notice, not an audit, and it has its own response process. See types of IRS audits.

How to decide: five questions to ask about your case

These questions usually decide it.

1. Can you prove your side with documents? If the examiner disallowed an expense because you never sent receipts, the first fix is to send them to the examiner before the deadline. Publication 5 says to make sure the examiner has everything you want considered before you appeal, because new information sent to Appeals will usually go back to the examiner first and slow the case.
2. Is the dispute about facts or about the law? Factual disputes turn on evidence; legal ones turn on authority, and Appeals weighs how a court would likely decide them.
3. How much is at stake, per year? The amount sets the paperwork. If the tax and penalties for each period are $25,000 or less, a short small case request is enough; above that, a formal written protest is required (Publication 5).
4. What does waiting cost? Interest runs on any tax you end up owing, at the federal short-term rate plus 3 percentage points, reset quarterly (7% (IRS.gov, Jul-Dec 2026) this quarter). An IRS tax tip on Appeals says interest “continues to add up on any unpaid balance” while Appeals reviews a case.
5. How much time is left on the assessment statute? Publication 3498 says you can’t appeal administratively unless enough time remains on the assessment statute when Appeals receives the case, “generally 365 days.” If time is short, the IRS will ask you to sign a consent to extend it. Publication 5 says that if you decline, “Appeals will not accept your case,” though you can still go to the Tax Court after the notice of deficiency. See how long an IRS audit takes.

What agreeing means

Publication 3498 says that if you agree, “you can sign an agreement form and pay any additional tax you may owe,” plus interest and any penalties. Signing is a written waiver of the restrictions on assessment, which the tax code allows “at any time” (IRC 6213(d)). In practice that means the IRS can assess the agreed tax without sending you a notice of deficiency, so the Tax Court route closes for the amount you agreed to.

• Pay what you can when you sign. Publication 3498 says that if you pay when you sign, interest is generally figured from the return’s due date to your payment date. If you can’t pay in full, it says to “pay whatever amount you can and request an installment agreement for the balance.” Our page on paying an audit bill you can’t afford covers the options, and IRS payment plans compared explains each plan.
• Agreeing is not the same as giving up all rights. If you later find proof the assessment was wrong and it is still unpaid, audit reconsideration may reopen it. If you pay and believe you overpaid, a refund claim is the route.

How the IRS Independent Office of Appeals works

Appeals is a separate office inside the IRS. By law its job is “to resolve Federal tax controversies without litigation” on a basis that “is fair and impartial to both the Government and the taxpayer” (IRC 7803(e)(3)). Publication 4227 says Appeals is “independent of the IRS office that proposed the adjustment” and avoids one-sided (ex parte) talks with other IRS employees that would compromise that independence.

What to expect, based on IRS publications and tax tips:

• Routing. Your request goes to the office that sent the 30-day letter, which tries to resolve the issues first and forwards the rest to Appeals.
• First contact. Once Appeals has the case, an Appeals officer contacts you “within 45 days by mail to schedule an informal conference.” If you’ve heard nothing and more than 120 days have passed since your request, you can ask the office you last worked with for a status update (IRS Tax Tip 2024-47).
• The conference. Conferences are informal and held by phone, video or in person; you choose. You can represent yourself or use an attorney, CPA or enrolled agent with a Form 2848.
• How Appeals weighs the case. Publication 4227 says the officer reviews “the strengths and weaknesses of the respective positions.” The IRS manual describes a fair settlement as one that “reflects, on an issue-by-issue basis, the probable result in the event of litigation” (IRM 8.6.4.2). That is what practitioners call settling on the hazards of litigation. Appeals does not settle for “nuisance value.”
• No new issues. Appeals “will not raise new issues or reopen issues agreed to by the taxpayer or the IRS,” except in cases of potential fraud or malfeasance (IRS Tax Tip 2023-80).
• New evidence goes back to the examiner. If you give Appeals new information, it will generally return the case to the examiner for comment first, and you get a chance to respond.
• Your case file. If you are a “specified taxpayer” (individuals with adjusted gross income of $400,000 or less for the year at issue; other taxpayers with gross receipts of $5 million or less), you are entitled to the nonprivileged case file no later than 10 days before a scheduled Appeals conference (IRC 7803(e)(7)).

The result can be that the IRS position stands, your position prevails, or a compromise. If no settlement is reached, Form 12203 says Appeals will send a notice of deficiency, and you can then petition the Tax Court. This page covers audit (examination) appeals. Collection appeals, such as CDP hearings and the Collection Appeals Program, follow different rules; see your rights in IRS collection.

Small case request or formal written protest

Publication 5 (Rev. 4-2021) says “you must submit a written protest to request an Appeals conference,” and that a formal protest is required unless you qualify for a small case request. The dividing line is $25,000 of tax and penalties per tax period, as shown in the letter you received.

A formal protest must include, per Publication 5:

• your name, address and a daytime phone number;
• a statement that you want to appeal the proposed changes;
• a list of every disputed issue, the tax periods involved, the proposed changes and why you disagree with each;
• the facts supporting your position on each issue;
• any law or authority supporting your position; and
• a signed penalties-of-perjury statement (Publication 5 gives the exact wording, and separate wording for representatives).

Fast Track Settlement for small businesses

Fast Track Settlement (FTS) is still offered. Publication 3498 describes it as a way “to resolve audit issues earlier and more efficiently during the examination process.” While your case stays with the examiner, a specially trained Appeals employee acts as a neutral mediator between you and the IRS.

• Who can use it. The IRS manual says FTS is “generally available for non-docketed SB/SE cases with no regard to dollar amount” (IRM 8.26.2). The issues must be fully developed, and you and the IRS must both agree to take part.
• What it covers. Publication 3498 says FTS fits “factual and legal issues, and issues requiring settlement based on the hazards of litigation.” Collection cases (CDP, Collection Appeals Program, offers in compromise) are excluded, and so are frivolous issues.
• How to start. Tell the examiner you want FTS. The application is Form 14017, signed by you, the examiner and the examiner’s manager.
• How long. The manual sets a goal of 60 calendar days from Appeals’ acceptance to closing.
• No downside to trying. You can withdraw at any time, and you keep your usual appeal rights on anything left unresolved.

The other route: Tax Court, or paying and suing for a refund

You don’t have to go to Appeals. You can let the 30-day letter lapse, wait for the notice of deficiency, and petition the U.S. Tax Court within 90 days (150 days if the notice is addressed to a person outside the United States) under IRC 6213(a). Publication 5 says this time is set by law and “the IRS or the U.S. Tax Court cannot change” it. The Tax Court’s filing fee is $60, and the court can waive it if you can’t pay.

• You still get a chance to settle. Publication 5 says that if you petition the Tax Court and did not appeal within the IRS first, “you will normally have an opportunity to attempt settlement with Appeals while you are waiting for your trial.” The Tax Court says “most cases are settled by mutual agreement without trial.”
• No statute pressure. Docketed Tax Court cases “do not have the statute of limitation concerns that non-docketed cases do” (Publication 5), so you won’t be asked to extend the assessment period to get into Appeals.
• Small disputes. If the deficiency in dispute, including penalties, is $50,000 (IRS.gov, 2026) or less for each year, you can choose the informal small tax case procedure. See Tax Court small case procedure.
• Pay first, then sue. The U.S. District Court and the Court of Federal Claims generally hear tax cases only after you have paid in full and filed a refund claim with the IRS (Publication 5).

Going to Appeals first doesn’t use up your Tax Court right: without a settlement, you still get the notice of deficiency. If you miss that petition deadline, see missed an IRS audit deadline.

Typical effects, not results: each case is decided on its facts.

Doing it yourself, free help, and when to bring in a professional

Many taxpayers handle a small case request alone; Form 12203 is one page. A representative is more useful when the amount needs a formal protest, when the dispute is about the law rather than missing receipts, when the IRS asks you to extend the statute, when several years or a business are involved, or when you are weighing Appeals against the Tax Court.

• Taxpayer Advocate Service. Free help if an IRS problem is causing financial hardship or normal channels have failed: 877-777-4778 (IRS.gov, 2026) or taxpayeradvocate.irs.gov.
• Low Income Taxpayer Clinics. Publication 5 says an LITC may represent you in Appeals for free or a small fee if you qualify.
• A representative. Only an attorney, CPA or enrolled agent can represent you before Appeals. Others can attend only as witnesses. Our page on audit representation explains what a representative does.

Global Gate Tax Relief’s team includes licensed tax attorneys, enrolled agents and CPAs. The free consultation reviews your report and IRS transcripts first, and if you can handle the appeal yourself, we will tell you. If the firm takes the case, it quotes a flat fee upfront and makes no promises about the outcome. Request a free case review or call 1-877-800-8180.
