Offers in compromise: the math the ads leave out
An offer in compromise settles tax debt for the taxpayer's reasonable collection potential — equity in assets plus a multiple of monthly disposable income — not for 'pennies on the dollar.' How RCP works, doubt-as-to-collectibility versus liability, and real acceptance odds.
An offer in compromise is a contract: the IRS accepts less than the full liability because the taxpayer offers at least what the government could realistically collect anyway. That number — reasonable collection potential (RCP) — is a formula, not a negotiation, and it is the reason "settle for pennies on the dollar" advertising misleads. Whether your debt settles for 5% or cannot settle at all depends entirely on your assets and income, and the IRS accepts roughly a third of the offers it receives. The program's official terms are at the IRS's offer in compromise page, including a pre-qualifier tool that applies the same math described below.
The RCP formula
For the standard ground — doubt as to collectibility — the IRS works from Form 656 and the Form 433-A (OIC) or 433-B (OIC) financial statements:
- Net realizable equity: quick-sale value of assets (typically 80% of fair market value) minus secured debt, across real estate, vehicles, bank accounts, retirement plans, and business assets.
- Future income: gross monthly income minus allowable expenses under IRS national and local standards — not actual spending. Private school, above-standard housing, and discretionary items are disallowed.
- The multiplier: monthly disposable income × 12 if the offer will be paid in five or fewer installments within five months (lump sum), or × 24 for periodic payments over up to 24 months.
A worked example: same taxpayer, $95,000 debt, and the offer floor under each payment structure.
| Component | Lump-sum offer | Periodic-payment offer |
|---|---|---|
| Net realizable equity in assets | $18,000 | $18,000 |
| Monthly disposable income | $400 | $400 |
| Income multiplier | × 12 = $4,800 | × 24 = $9,600 |
| Minimum acceptable offer (RCP) | $22,800 | $27,600 |
That taxpayer legitimately settles $95,000 for about $23,000 — a genuine "pennies" outcome. Change one fact — $150,000 of home equity — and RCP exceeds the debt, and no offer will ever be accepted. The formula, not persuasion, decides.
Doubt as to liability is a different animal: the claim is that the assessment itself is wrong. It is filed on Form 656-L with no financial disclosure and no application fee, and it is evaluated like a merits dispute — useful where audit reconsideration or Appeals rights were missed. A third ground, effective tax administration, covers rare hardship or equity cases where RCP technically covers the debt.
The realities the ads omit
- Compliance gates. All required returns filed and current-year estimated payments made, or the offer is returned unprocessed. Acceptance also requires staying compliant for five years, or the compromised debt springs back.
- The pending offer has costs. It suspends the 10-year collection statute, so a rejected offer leaves the IRS with more time to collect — and a complete map of your finances. Taxpayers near the CSED often do better with currently-not-collectible status, as discussed in the collection defense guide.
- Rejection is appealable. A rejected offer can go to Appeals, and an offer proposed during a CDP hearing gets Tax Court review of Appeals' refusal for abuse of discretion.
Frequently asked questions
- How does the IRS decide whether to accept an offer in compromise?
- The IRS computes your reasonable collection potential: the net realizable equity in everything you own, plus your monthly income minus allowable living expenses, multiplied by 12 for a lump-sum offer or 24 for a periodic-payment offer. If your offer equals or exceeds that number — and you are compliant with filings and current-year payments — it is acceptable. If your RCP exceeds the debt, no offer amount works.
- What percentage of offers in compromise are accepted?
- Historically, roughly a third of submitted offers are accepted — in recent years the IRS has received on the order of 30,000-plus offers annually and accepted around a third of them. Most rejections happen because the taxpayer's reasonable collection potential exceeds the offer, often because the taxpayer could full-pay through an installment agreement.
- What is the difference between doubt as to collectibility and doubt as to liability?
- Doubt as to collectibility means the tax is correct but the taxpayer cannot pay it; the offer is judged against reasonable collection potential. Doubt as to liability means the assessed tax itself is probably wrong; it is filed on Form 656-L, requires no financial disclosure, and is evaluated on the merits of the tax dispute rather than on ability to pay.
