IRS audit reconsideration checklist

Use this checklist to prepare a focused request for the IRS to reevaluate a closed audit. It does not replace a current protest, court petition, collection appeal, refund claim, or other deadline.

Do not sacrifice another review right

List every deadline in the audit, collection, refund, and court notices before relying on audit reconsideration.

1. Confirm the process fits

  • Examination is closed and an assessment is on the account.
  • Tax remains unpaid or a credit was denied.
  • New or previously unconsidered evidence identified.
  • Missed audit, address problem, or computational or processing error documented.
  • No final court determination or controlling closing agreement identified.
  • Open-audit protest and Tax Court rights checked separately.

2. Collect the audit record

  • Examination report and all attachments.
  • Form 4549, when available.
  • IRS letters, notice numbers, dates, and tax periods.
  • List of documents the examiner says were considered.
  • Account transcript or online-account record used only as supporting context.

3. Map each disputed issue

  • Separate line for each adjustment.
  • Amount claimed on the return recorded.
  • Amount allowed in the audit report recorded.
  • Reason for disagreement stated in plain language.
  • Evidence linked to the matching issue number.

4. Prepare supporting copies

  • New receipts, checks, statements, tax forms, logs, or eligibility records gathered.
  • Documents matched to the audited tax year.
  • Previously sent item explained when it was apparently not considered.
  • Original documents retained; readable copies prepared.
  • Sensitive identifiers placed only in the official IRS submission.

5. Draft the request

  • Letter clearly asks for audit reconsideration.
  • Taxpayer name, tax period, and examination reference included as instructed.
  • Each disputed adjustment explained.
  • Form 12661 downloaded from IRS.gov and used when helpful.
  • Copy of Form 4549 attached when available.
  • Daytime contact information included only in the official submission.

6. Confirm the filing channel

  • Correspondence-audit Document Upload Tool checked when applicable.
  • Address on the current audit letter verified.
  • IRS office contacted when the correct destination is uncertain.
  • No address copied from an old third-party guide.
  • Every uploaded, mailed, or faxed page reviewed for readability.

7. Protect collection and payment obligations

  • Installment-agreement payments continued.
  • Collection notices reviewed for separate appeal rights.
  • Form 12153 deadline protected when a CDP notice applies.
  • Interest and penalty accrual considered.
  • Hardship assistance considered separately when needed.

8. Keep proof and follow up

  • Complete request copy saved.
  • Upload confirmation or mailing proof retained.
  • Thirty-day follow-up point noted without treating it as a decision deadline.
  • Requests for more information answered promptly.
  • Final reconsideration letter reviewed for Appeals, payment, or refund-claim options.
