IRS Audit Reconsideration: How to Reopen or Challenge an Audit
Last updated 09/17/2025 by

Quick answer: IRS audit reconsideration lets taxpayers contest audit results if new evidence emerges, taxes were paid in error, or the IRS didn’t consider documentation. File by responding to the notice (such as CP14) with supporting documents, or use Form 1040X and a written request. While not guaranteed, reconsideration can reduce or reverse balances and stop enforced collection.
Audit reconsideration is one of the IRS’s built-in remedies if you believe the outcome of an audit was wrong. Unlike an appeal, this process reopens the case to review new or overlooked information.

When can you request audit reconsideration?
- You have new documentation that wasn’t previously reviewed.
- You believe the IRS made a computational or clerical error.
- You never received the audit notice or couldn’t respond on time.
- You already paid the balance but think it was assessed incorrectly.
When you cannot use audit reconsideration
- If you already signed a closing agreement (Form 906).
- If you agreed to the liability in Tax Court.
- If you’ve already used the reconsideration process for the same issue.
Steps to request audit reconsideration
- Review your notice: Identify which tax year and issue are under dispute. Most taxpayers see a CP14 (balance due) or follow-ups like CP501 or CP503.
- Gather documentation: Collect receipts, statements, mileage logs, or other proof supporting your claim.
- Prepare your request: Write a letter explaining why the audit result is incorrect, attach documentation, and include copies of the IRS notice.
- Submit Form 1040X (if needed): If the adjustment involves correcting your return, attach a completed amended return.
- Mail to the address on your notice: Use certified mail for tracking.
What happens after you file?
- The IRS suspends collection on the disputed portion while reconsideration is pending.
- You may receive a letter asking for more information.
- If accepted, your balance is reduced or eliminated. If denied, you can appeal or pursue other relief.
Audit reconsideration vs. appeal
| Feature | Audit Reconsideration | IRS Appeal |
|---|---|---|
| Purpose | Reopen audit with new evidence | Challenge IRS determination through Appeals Office |
| When used | After audit results, usually balance due notices | Before paying tax, after receiving final determination |
| Documentation | New or missing receipts, records, statements | Legal and procedural arguments |
| Outcome | IRS may reduce or remove balance | Appeals Office may uphold, reduce, or overturn IRS decision |
Real-life scenarios
- Missed audit: A taxpayer out of the country missed the audit letter. On reconsideration, they submitted receipts and the IRS reduced the balance.
- New documents: A freelancer found bank statements proving income was reported correctly. Audit reconsideration cleared the underreporting claim.
- Wrongful payment: A taxpayer paid after an audit but later proved medical deductions were valid. The IRS refunded part of the payment after reconsideration.
Core Takeaways
- Audit reconsideration reopens an IRS audit if new evidence or errors are found.
- It pauses collection while under review.
- Submit a written request with supporting documents; use Form 1040X if a correction is needed.
- If denied, you can still appeal or explore relief programs.
