Introduction

When the IRS denies an Offer in Compromise (OIC), the decision isn’t always final. You may request reconsideration if you have new, material information or if the denial was based on incorrect facts. The process and deadlines are stated in your rejection letter, so start there first. For background on the OIC program see the IRS OIC page (IRS.gov).

Step-by-step checklist to request reconsideration

  1. Read the rejection letter carefully
  • Note the reason(s) for denial and any appeal/reconsideration deadline. The letter will also state where to send additional information.
  1. Confirm eligibility to request reconsideration
  • Any taxpayer with a denied OIC can request reconsideration, particularly when there is newly discovered evidence or a material change in financial circumstances (job loss, medical emergency, bankruptcy filing, etc.).
  1. Gather and update documentation
  • Update your Collection Information Statement (the OIC financial statement you originally filed) — for example, the forms commonly used in OIC submissions are the financial statement required with Form 656 and the related Form 433 series. Provide recent pay stubs, bank statements, bills, medical records, or proof of reduced income.
  1. Prepare a clear cover letter
  • Reference the IRS case or proposal number shown on the rejection letter. Explain briefly and specifically why the denial should be reconsidered and list the new or corrected documents you’re providing.
  1. Submit your packet to the address given on the denial
  • The rejection notice will usually tell you where to send reconsideration materials. Follow those instructions exactly and keep copies of everything you submit.
  1. Consider asking for Appeals review if appropriate
  • If the denial notice explains how to appeal, you may request review by the IRS Independent Office of Appeals. The denial letter will describe appeal rights and any deadlines — follow those instructions to preserve appeal rights.

What to include in a strong reconsideration packet

  • A concise cover letter referencing the denial date and case number.
  • An updated OIC financial statement (updated Form 433-series information) and a statement of changed circumstances.
  • New supporting documents (recent pay stubs, evidence of lost income, medical bills, business records, settlement statements, etc.).
  • A copy of the denial/rejection letter and your originally filed OIC.

Timeline and what to expect

  • Deadlines: The denial letter controls. Many letters give about 30 days to appeal or request further review, but you must confirm the exact period on your notice.
  • Processing time: Reconsideration can take weeks to several months depending on complexity and whether additional verification is needed. Stay current with tax filings and any required payments while the case is pending.

Common mistakes to avoid

  • Missing the deadline listed on the rejection notice — always act promptly.
  • Sending the same information without new evidence — reconsideration requires new or corrected facts.
  • Failing to include the case number or a clear identifier — this slows processing.
  • Not keeping records of what you submitted (use certified mail or trackable delivery).

When to hire a tax professional

If your case is complex (business closures, significant asset valuation disputes, bankruptcy intersections, or litigation risk), get representation from a CPA, enrolled agent, or tax attorney experienced with offers in compromise. In my practice I’ve seen well-prepared reconsideration packets accepted when they included current financials and credible supporting documentation.

Alternatives and next steps

If reconsideration is denied or appeal rights have lapsed, other options may include negotiating an installment agreement, pursuing a partial-payment installment agreement, or exploring bankruptcy (depending on circumstances).
