Offer in Compromise After Acceptance: The 5-Year Rules

Acceptance is not the end of an Offer in Compromise — it is the start of a five-year compliance period during which the IRS can unwind the entire settlement if you slip. No consumer guide ranking for this topic assembles the full rulebook, so here it is, from the IRS FAQ and the Form 656 terms you signed: what you must pay, what the IRS keeps, when the lien comes off, the one extension that exists, and exactly how defaults happen.

General tax information, not tax or legal advice.

Rule 1 — Pay the offer exactly as accepted

• Lump-sum offers: the remaining balance in five or fewer payments within five months of acceptance.
• Periodic offers: payments continue on schedule until the offer amount is complete (within 24 months). Payments go to the address specified in your acceptance letter, designated to your offer where instructed (the IRS FAQ’s “Where do I send my payments?” answer points to the letter — follow it over any generic notice).

Rule 2 — The IRS keeps your refunds (for a while)

Refunds for tax years through the year the offer is accepted are applied to your tax liability — they are not refunded to you and do not count as offer payments. If the IRS accepts your offer in 2026, your 2026 refund (filed in 2027) is kept. Plan withholding accordingly: over-withholding during the acceptance year is a donation to the balance you already settled.

Rule 3 — The lien stays until the offer is paid in full

A federal tax lien is not released at acceptance. Release comes when the offer amount is paid in full and the IRS processes the certificate of release — verify it, because credit and property transactions will ask (context in the collections cluster).

Rule 4 — Five years of perfect filing and payment compliance

For five years after acceptance (including any extension period of the final tax year), you must:

• File every required return on time (valid extensions count — file by the extended date)
• Pay all taxes in full and on time, including estimates/withholding tuned so no new balance arises This duty is a term of the compromise itself (Form 656’s conditions; Ohio’s AG FAQ asks about post-acceptance duties for its state programme — the federal duty is this rule). Treat estimated payments like a covenant: one surprise balance in year 3 is the classic default trigger.

The one extension that exists

The IRS FAQ acknowledges a limited accommodation: if you cannot make an offer payment on time, contact the IRS before the due date — a short, one-time extension may be granted in appropriate cases. What does not exist: retroactive forgiveness for silent missed payments (the related question, “Can I have an extension on offer payments after my offer has been accepted?”, is the IRS FAQ’s own).

Default: what happens if you break the rules

The IRS may terminate the compromise and reinstate the full original liability — the entire pre-offer balance, plus interest and penalties for the whole period, minus payments actually made. The 6–24 months you spent, the fee, and the settlement itself: gone. Default usually follows a notice and a chance to cure — do not ignore that letter; curing a compliance slip inside the notice window is the last exit.

When you finish paying (closing checklist)

1. Keep the IRS’s confirmation that the offer amount is satisfied.
2. Verify the lien release was filed (county records / IRS lien unit).
3. Confirm remaining years of the 5-year compliance period still ahead — finishing payments does not shorten it.
4. Adjust withholding so the refund-offset rule (Rule 2) stops costing you once it expires. The IRS FAQ’s own closing question — “I finished making my offer payments, what do I do now?” — is answered by exactly this checklist: the payments end the debt work; the compliance calendar runs on.

Frequently asked questions

What happens if the IRS accepts my offer in compromise? Your offer amount becomes the full settlement of the listed periods — conditioned on paying it as agreed and completing the 5-year compliance period. The IRS FAQ section of this name covers the acceptance letter, payment terms, refund offsets, and lien timing assembled above (irs.gov).

Upon acceptance of an offer, does an applicant have any duties and/or responsibilities other than signing of the Offer-in-Compromise Agreement and payment of the offer amount? Yes — Ohio AG’s FAQ asks this verbatim (for its state programme); federally the added duties are the 5-year timely-filing and full-payment compliance rule and cooperation terms in Form 656. Acceptance is a contract, not a receipt.

Can I have an extension on offer payments after my offer has been accepted? Possibly, once, if you ask before the payment is due and circumstances justify it (IRS FAQ). Silence followed by a missed payment is the default path, not the extension path.

I finished making my offer payments, what do I do now? Verify the IRS records the offer as satisfied, confirm the lien release, and calendar the remainder of your 5-year compliance period (IRS FAQ closing item — expanded in the checklist above).

Where do I send my payments? To the address in your acceptance letter, with the designation the letter specifies (IRS FAQ). Do not substitute the address from a stray balance-due notice.
