How To Appeal an IRS Decision

The IRS Office of Appeals is designed to resolve tax disputes without going to court. It operates independently from the audit and collection functions, which helps ensure an impartial review. A successful appeal can reduce or eliminate taxes and penalties, but only if your position is grounded in tax law and supported by facts.

When an appeal applies

The IRS typically proposes changes to your tax return through an audit or takes collection action. If you disagree with an IRS decision, your first step is to respond to the office that issued it and attempt to resolve the issue directly. That office will review your response and may revise its position.

If you still cannot reach an agreement, you can request that your case be sent to the IRS Office of Appeals. At that point, the process shifts. Instead of continuing back and forth with the original office, the Office of Appeals independently evaluates the strengths and weaknesses of both sides and determines how the case would likely be resolved under tax law.

The appeals process does not reconduct the audit; it assesses whether the IRS’ position is likely to be upheld if the case were to go to court. This means that documentation, consistency and credibility are crucial.

How to start the process

To request an appeal, most taxpayers must submit a written protest. This document should clearly state:

• The items you disagree with
• The facts supporting your position
• The applicable tax law or authority

If the total amount of proposed tax, penalties and interest for each tax period is $25,000 or less, you may qualify for a simplified “small case request,” which requires less documentation.

In many cases, you must file your protest within 30 days of the IRS notice that grants you appeal rights — typically a letter proposing changes after an audit, although some notices may allow different response time frames. Missing that deadline can limit or eliminate your ability to have the case reviewed by the Office of Appeals.

If your dispute involves a collection action — such as a lien, a levy or an installment agreement — different procedures apply, and specific IRS guidance governs those appeals.

If your request is granted, an appeals officer will review your case independently and may ask for additional information. You will be given a specified response time frame, determined by the appeals officer, which varies by case.

Why professional guidance matters

When it comes to the appeals process, most people are best served by hiring a professional, such as an attorney, a certified public accountant or an enrolled agent. They can assess whether your position is legally supportable and help structure your argument effectively. They can also communicate with the IRS directly on your behalf if you grant them power of attorney (Form 2848).

What determines success

Appeals are decided based on facts and law, not on arguments of frustration or fairness. Strong cases typically:

• Clearly identify the disputed issues.
• Present organized, credible documentation.
• Align arguments with established tax law.
• Maintain a professional, cooperative tone.

Weak or unsupported claims are unlikely to succeed, regardless of the circumstances.
