Yes, you can appeal an IRS audit decision if you disagree with the findings. After an audit concludes, the IRS sends a 30-day letter outlining the proposed changes to your return. This letter explains your right to request an appeal through the IRS Office of Appeals before any adjustments become final.

The Appeals Office operates independently from the examination division that audited you. The appeals officer reviews your case fresh without any involvement in the original audit. Their job is to settle disputes without Tax Court litigation, which gives them authority to negotiate and compromise in ways the original examiner couldn’t.

To start an appeal, submit a formal written protest within 30 days of the letter date. For disputes under $25,000, a brief written request explaining your disagreement is sufficient. For larger amounts, you need a detailed protest letter laying out which items you disagree with, the facts supporting your position, the relevant tax law, and documentation backing up your case.

After you file your protest, the Appeals Office schedules a conference to discuss your situation. This can happen by phone, video, or in person. The appeals officer will listen to your position, ask questions, and weigh the strengths of both sides. Settlements often land somewhere between what you claimed and what the auditor proposed.

Miss the 30-day deadline and the IRS issues a Notice of Deficiency. That starts a 90-day clock to petition Tax Court. Once both deadlines pass, you’ve lost your appeal options and owe whatever the IRS determined.

Not every audit result is worth appealing. If the IRS found legitimate errors and you actually owe the tax, appealing just delays payment and adds interest. But if you have solid documentation the auditor dismissed or if they misapplied tax law to your situation, Appeals often reaches different conclusions.

Having IRS audit representation during the appeals process makes a real difference. Enrolled Agents are federally licensed to represent taxpayers before the IRS, including at Appeals conferences. They know which arguments work, how to present evidence effectively, and when a settlement offer is fair versus when you should keep negotiating.

If you’re facing an audit result you believe is wrong, don’t assume you have to accept it. The appeals process exists specifically so taxpayers can challenge IRS decisions through an independent review. A Nampa business tax preparation service with Enrolled Agents on staff can walk you through whether appealing makes sense and handle the process if you decide to move forward.
