Offer in Compromise: How It Really Works (and How the IRS Decides)

Every offer must be based on one of three grounds, and they are evaluated completely differently:

The IRS will not consider a doubt-as-to-liability offer and a doubt-as-to-collectibility offer at the same time. If you genuinely dispute the tax itself, resolve that question first, because a collectibility offer starts from the premise that the debt is valid.

For the standard doubt-as-to-collectibility offer, the IRS computes your reasonable collection potential in two parts.

Part one: net realizable equity in assets. The IRS values what you own at quick-sale value, generally 80 percent of fair market value, then subtracts loan balances. Form 433-A (OIC) applies the 80 percent discount line by line to real estate, vehicles, and retirement accounts, and it builds in a few taxpayer-friendly exclusions, including the first $1,000 of bank account balances and an allowance of $3,450 against the value of a vehicle.

Part two: future income. The IRS takes your monthly income, subtracts allowable living expenses under its Collection Financial Standards, and multiplies what is left by a fixed number of months that depends on how you structure the offer:

Add the two parts together and you have your RCP, which is the minimum the IRS expects your offer to match. Notice the structural quirk: a lump-sum offer uses half the future-income multiplier of a periodic offer, so taxpayers who can raise cash quickly, sometimes from family, often qualify for a meaningfully smaller settlement. The full mechanics of the financial disclosure are covered in our Form 433-A guide.

A standard offer package is Form 656 plus a completed Form 433-A (OIC) collection information statement (Form 433-B (OIC) for businesses), supporting documents, and two payments:

• Application fee: $205, non-refundable.
• Initial payment. For a lump-sum offer, 20 percent of the offer amount. For a periodic offer, the first proposed monthly installment, with continuing monthly payments while the IRS considers the offer.

Both the fee and all payments during consideration are waived under the low-income certification, which you meet if your adjusted gross income, or your household's gross monthly income times 12, is at or below the amounts in the Form 656 table, set at 250 percent of the federal poverty guidelines for your family size. The IRS verifies the certification, but if you qualify, you can have a complete offer considered without sending any money.

Filing an offer changes your relationship with IRS collections immediately, in ways that cut both directions:

• Collection generally pauses. The IRS suspends other collection activities while it evaluates the offer, and a levy placed after the IRS received your offer can usually be removed. Levies already in place before you filed may stay.
• A lien can still be filed. The IRS may file a Notice of Federal Tax Lien to protect its position while the offer is pending, and an existing lien is not released until the offer terms are fully satisfied.
• Existing installment agreements are suspended. You do not make payments on an existing installment agreement while the offer is being processed.
• The collection clock stops. The 10-year collection statute expiration date is suspended the entire time your offer is pending, plus 30 more days if the offer is rejected, plus the entire time any appeal is pending. A failed offer hands the IRS back every month it spent considering it, which is exactly why filing a hopeless offer to "buy time" is usually a bad trade. See how the CSED works.
• The IRS keeps your refunds. Tax refunds due through the date the offer is accepted are applied to the debt, not sent to you.

The IRS says a complete offer investigation can take up to 24 months depending on inventory and complexity; in practice, many straightforward offers resolve in 6 to 12 months. There is a hard backstop in your favor: if the IRS does not make a determination within two years of receiving the offer, it is automatically accepted by operation of law. If the offer is rejected, you have 30 days from the rejection letter to appeal.

Then there is the number the industry's advertising never mentions:

Read the acceptance rate correctly. It does not mean an OIC is a lottery ticket. It means the pool of submitted offers is polluted with applications that never had a chance because nobody computed the RCP first. For taxpayers whose finances genuinely support an offer, prepared with complete documentation, the odds look nothing like 14 percent.

An accepted offer is a contract, and Form 656 contains a condition many people learn about too late: for the five years after acceptance you must timely file every required return and timely pay every tax due. Miss a filing deadline or fall behind on a new balance during that window and the IRS can declare the offer in default and reinstate the original debt, minus payments made, with penalties and interest running again.

Two other post-acceptance rules matter for planning. You cannot submit a new offer for another liability during the five-year period. And self-employed taxpayers, the group most likely to need an OIC in the first place, should treat quarterly estimated taxes as non-negotiable, because a missed quarter that turns into a balance due is the most common way accepted offers die.

You have heard the ads: "settle your tax debt for pennies on the dollar." Some accepted offers genuinely do settle large debts for small amounts, because the formula produced a small RCP. The problem is firms that quote a settlement figure during a sales call, before anyone has seen your assets, income, transcripts, or expense picture. That is not analysis. Nothing about an OIC can be predicted without the financial data the formula runs on, and the Federal Trade Commission has repeatedly taken action against tax relief operations built on exactly this pitch.

A legitimate practitioner does the work in the opposite order: pull your account transcripts, build your RCP, and then tell you whether an offer clears the bar, and at what amount. Sometimes the honest answer is that an offer will not work and a different resolution will. What that engagement should cost, and the warning signs to watch for, are covered in what tax relief really costs and is tax relief legit.

An offer in compromise is one tool on a shelf, and it competes with alternatives that are faster, cheaper, and easier to get:

The right choice depends on your RCP, your CSED dates, and where your income is headed. If you want the math run properly before anything is filed, a free consultation with a resolution specialist on our team starts with your transcripts and the formula, not a quote.
