The IRS Offer in Compromise (OIC) program allows qualifying taxpayers to settle their entire tax debt — including penalties and interest — for less than the full amount owed. In recent years, the IRS has accepted roughly 30–40% of submitted offers, settling billions in tax liability for a fraction of the total.
But this isn't a "pay pennies on the dollar" scheme the way late-night commercials suggest. The IRS has a precise formula for determining how much you're required to pay. If your offer is below that number, it will be rejected. Understanding how the math works is the key to submitting an offer that actually gets accepted.
The Three Bases for an Offer in Compromise
The IRS accepts OICs on three distinct legal grounds. You must qualify under at least one.
1. Doubt as to Collectibility (Most Common)
You agree that you owe the tax, but you're arguing that the IRS will never be able to collect the full amount from you — because your income and assets simply aren't sufficient to pay the debt in full before the 10-year Collection Statute Expiration Date (CSED).
This is by far the most common basis, and it's what most people mean when they talk about settling with the IRS.
2. Doubt as to Liability
You're disputing that you actually owe the tax at all, or that the assessed amount is correct. This might apply if:
- You were audited and the auditor made errors
- You have documentation the IRS never considered
- There was a miscalculation in the original assessment
Important: You cannot use doubt as to liability if you've already gone through Tax Court on the same issue. And you must act before the assessment becomes final.
3. Effective Tax Administration (ETA)
You agree you owe the tax and the IRS could technically collect it — but requiring full payment would create an economic hardship, or collecting the full amount would be unfair or inequitable given exceptional circumstances.
ETA offers are rare and difficult to get approved. They're typically used for cases involving permanent disability, elderly taxpayers with limited remaining life expectancy, or situations where a taxpayer's only asset is a home that would need to be sold, leaving them homeless.
How the IRS Calculates Your Reasonable Collection Potential (RCP)
For doubt as to collectibility offers, the IRS calculates a number called Reasonable Collection Potential — the minimum offer amount they'll accept. If you offer less than RCP, it's automatically rejected (unless you provide documentation explaining why).
RCP = Remaining Equity in Assets + Future Income Component
Equity in Assets
The IRS looks at the quick-sale value of everything you own:
- Bank accounts (100% of balance)
- Investment accounts (100%)
- Home equity (fair market value × 80%, minus mortgages)
- Vehicles (loan value × 80%, minus loans)
- Business assets
- Retirement accounts (this is where many taxpayers are surprised — the IRS counts retirement account balances at their present value, not what you'd net after taxes and penalties)
Future Income Component
This is calculated one of two ways depending on your payment terms:
- Lump sum offer (paid within 5 months): Monthly disposable income × 12
- Periodic payment offer (paid over 6–24 months): Monthly disposable income × 24
Monthly disposable income = gross monthly income minus IRS-allowed monthly living expenses. The IRS uses national and local standard expense amounts — not necessarily what you actually spend. If the standards say you can live on $600/month for food but you spend $1,000, the IRS uses $600 in the calculation.
Example: You have $5,000 in bank accounts, $10,000 in home equity (after the 80% haircut), no retirement savings, and $300/month in disposable income. For a lump sum offer: RCP = $15,000 + ($300 × 12) = $18,600. That's the minimum the IRS will accept.
The Form 656 Process
Submitting an OIC involves two forms:
- Form 656: The actual offer form — lists your proposed payment amount and terms
- Form 433-A (OIC): Detailed financial disclosure — every asset, income source, monthly expense, and debt you have
You must also submit a $205 non-refundable application fee (waived for low-income applicants) and an initial payment:
- Lump sum: 20% of your offer amount with the application
- Periodic payment: Your first monthly payment with the application
The IRS has 24 months to accept or reject your offer. If they don't act within 24 months, the offer is deemed accepted by operation of law.
What Kills an OIC Application
The most common reasons offers are rejected:
1. Filed or unfiled returns: You must have filed all required tax returns for all years. Any unfiled return is an automatic rejection.
2. Estimated tax payments: If you're self-employed, you must be current on estimated quarterly payments.
3. Open bankruptcy: You cannot submit an OIC while in an active bankruptcy case.
4. Offer below RCP: If you offer less than the calculated RCP without explaining unusual circumstances, it will be rejected.
5. Dissipated assets: If you recently transferred or spent down assets, the IRS adds those back into the RCP calculation as "dissipated assets."
6. Missing documentation: Incomplete Form 433-A, missing bank statements, or unexplained income discrepancies trigger rejections.
What Happens While Your Offer Is Pending
Once the IRS accepts your offer for processing:
- Collection activity is suspended (levies, garnishments stop)
- The 10-year collection statute is tolled (paused) — meaning the clock stops running while the offer is under review, and for 30 days after rejection
- You must continue to file all returns on time and stay current on any tax obligations for the year
If you're rejected, you have 30 days to appeal to the IRS Independent Office of Appeals.
A Note on Tax Relief Companies
Many OIC advertisements are misleading. The "pennies on the dollar" framing obscures the fact that the IRS has a formula — your offer isn't negotiated down from the full balance, it's calculated based on your actual financial situation. Hiring an expensive tax relief company won't get you a better deal than the formula produces.
What you actually need is accurate financial disclosure and documentation. A CPA or enrolled agent can be worth it for complex situations, but the math is objective.
