What Is IRS Form 12203?

Form 12203, titled Request for Appeals Review, is a one‑page document used by taxpayers to ask the IRS Appeals Office to reconsider audit findings. It is designed for “small‑case” disputes, meaning the total amount in controversy does not exceed $25,000.

When Can You Use Form 12203?

• After the audit is complete and you have received an audit letter.
• The disputed amount is $25,000 or less for each tax year.
• You want to appeal without first filing a formal written protest.

Common Mistakes to Avoid

• Using the wrong form: Form 12203 is only for cases ≤ $25,000. Larger disputes require Form 12204.
• Leaving fields blank: Incomplete taxpayer information can delay processing.
• Not attaching supporting documentation: Include any relevant statements, receipts, or legal citations.
• Misspelling names or SSNs: Errors cause the IRS to reject the appeal.

By following these steps and double‑checking your entries, you’ll increase the chance that the Appeals Office reviews your case promptly.
