Offer in Compromise Calculator (2026): Estimate What the IRS Might Accept

Estimate Your Offer in Two Minutes
An Offer in Compromise (OIC) lets you settle your IRS tax debt for less than the full amount you owe — but only if the numbers support it. The IRS doesn't negotiate based on hardship stories; it runs a formula. This free calculator runs the same style of math the IRS uses, so you can see in about two minutes whether an offer is even worth pursuing before you spend a dollar on representation.
I'm a licensed Enrolled Agent and I prepare and negotiate offers for clients across all 50 states. Everything below reflects how the IRS actually evaluates offers in 2026 — including the exact formula, the two payment options, and the traps the calculator can't see.
How the IRS Actually Decides: Reasonable Collection Potential
The IRS accepts an offer when the amount you propose equals or exceeds your Reasonable Collection Potential (RCP) — its estimate of everything it could realistically collect from you. RCP has two parts: the net equity in your assets, and a multiple of your monthly remaining income.
Asset equity is calculated at quick-sale value: generally 80% of market value, minus any loans against the asset. The IRS also excludes the first $1,000 in your bank accounts and up to $3,450 of equity per vehicle. Future income is your gross monthly household income minus your allowable living expenses — and 'allowable' is the key word. The IRS caps most expense categories at its published Collection Financial Standards for your county and household size, not at what you actually spend.
Lump Sum vs. Periodic Payment: Why the Choice Changes Your Number
A lump-sum cash offer (paid in 5 or fewer payments within 5 months of acceptance) multiplies your monthly remaining income by 12. A periodic payment offer (paid over 6 to 24 months) multiplies it by 24 — double. That single choice can swing your offer amount by tens of thousands of dollars, which is why the calculator lets you toggle between both.
Lump sum is almost always the smaller total number if you can fund it — from savings, family help, or borrowing. Periodic spreads the cost but raises the target, and you must keep making the payments while the IRS reviews the offer.
What the Calculator Can't See
A calculator estimates the math; it can't clear the eligibility gates. Before the IRS will even process an offer, you must have every required tax return filed and be current on this year's withholding or estimated payments. If you're in an open bankruptcy, you're ineligible.
The IRS also looks backward: assets you sold, gave away, or spent down while the tax debt was accruing (called dissipated assets) can be added back into your RCP as if you still owned them. And special categories exist — doubt as to liability, and Effective Tax Administration offers for people whose numbers technically fail but where collection would create economic hardship. Those need a professional's judgment, not a slider.
Offer in Compromise Costs and Rules in 2026
Filing an offer costs a $205 application fee, and a lump-sum offer must include 20% of the offered amount up front — both non-refundable if the offer is rejected. If your household income is at or below 250% of the federal poverty guidelines, the Low-Income Certification waives the fee, the down payment, and payments during review.
While an offer is under review, IRS collection generally pauses. Expect the review to take several months to a year. If your offer is accepted, you must stay compliant — file and pay on time — for the next five years, or the settled debt comes back.
Do You Actually Qualify? A Quick Checklist
You're a realistic OIC candidate if: your estimated offer (from the calculator above) is meaningfully less than your total debt; all your returns are filed; you're current on this year's payments; your income has genuinely dropped or your expenses legitimately consume it; and you can fund the offer if accepted. If your RCP comes out higher than your balance, an offer will be returned — but that doesn't mean you're stuck. Installment agreements, penalty abatement, and Currently Not Collectible status are all live alternatives, and sometimes they're the better tool anyway.
Frequently Asked Questions
How much will the IRS settle for in an Offer in Compromise?
There is no fixed percentage. The IRS accepts what your Reasonable Collection Potential supports: your net asset equity plus 12 or 24 months of your remaining monthly income. Someone with little equity and no monthly surplus can settle a large balance for a small fraction; someone with home equity may not qualify at all. The calculator above estimates your specific number.
What is the lowest amount the IRS will accept?
The IRS will accept an offer as low as your RCP calculates — accepted offers can be under $1,000 on large balances when the financials genuinely support it. But the offer must at least equal RCP; lowballing below your computed number gets the offer rejected.
Is the IRS Fresh Start program real?
'Fresh Start' is a marketing name for real IRS programs — the Offer in Compromise, streamlined installment agreements, and lien threshold changes. There is no secret amnesty beyond these. Anyone promising 'pennies on the dollar' without running your financials first is selling, not advising.
How long does an Offer in Compromise take in 2026?
Plan on 6 to 12 months from filing to decision, sometimes longer if the offer is assigned for deeper review. Collection activity generally pauses while it's pending. If the IRS doesn't act on the offer within two years, it's deemed accepted by law.
What happens if my offer is rejected?
You have 30 days to appeal through the IRS Independent Office of Appeals, and appeals overturn a meaningful share of rejections. If the appeal fails, your $205 fee and any 20% down payment are applied to your balance, and you pivot to an installment agreement or Currently Not Collectible status.
Can I file an Offer in Compromise myself?
Yes — Form 656 and Form 433-A(OIC) are public. But the offer amount turns on valuation judgment calls: which expenses count, how assets are valued, what's excluded. Most rejected offers fail on avoidable documentation and math issues. A licensed representative also keeps the IRS talking to them, not you.
