IRS Form 656: How to File an Offer in Compromise, Step by Step

By the Sasquatch Tax team · Published July 6, 2026

Form 656 is the application for an IRS Offer in Compromise, the program that settles tax debt for less than the balance when the numbers support it. The form itself is short. The real work is the financial statement behind it, Form 433-A (OIC), and getting the offer amount right before the IRS calculates it for you. Here is the whole process in order.

Step 1: Confirm you can even apply

The IRS returns offers, without considering them, when the basics aren't met. Before touching the form:

• All required tax returns are filed. (Unfiled years? Fix that first.)
• You've made this year's required estimated tax payments. This is the one self-employed applicants miss most.
• You're not in an open bankruptcy case.

The IRS's own Offer in Compromise Pre-Qualifier tool (on irs.gov) gives a fast preliminary read on eligibility and a rough offer figure. It isn't binding, but it catches disqualifiers early, for free.

Step 2: Build the financial statement — Form 433-A (OIC)

This is where offers are won or lost. Form 433-A (OIC) (433-B (OIC) for businesses) documents your bank accounts, vehicles, equipment, real estate, retirement funds, monthly income and monthly expenses, backed by roughly three months of supporting statements. Two things matter most:

• Asset valuation. Assets generally count at quick-sale value with allowable reductions, not sticker price.
• Allowable expenses. The IRS measures your spending against its national and local expense standards, not your actual lifestyle. Documented, allowable expenses lower your offer; undocumented ones vanish from the math.

Step 3: Calculate the offer amount

The IRS accepts an offer that equals or exceeds your Reasonable Collection Potential: net asset equity plus future monthly income (income minus allowable expenses) times a multiplier: 12 for a lump-sum offer, 24 for a periodic-payment offer. The OIC service page walks the RCP math in detail. Offer too little and it's rejected; offer meaningfully more than RCP and you overpay. Getting this one number right is most of the reason people hire help.

Step 4: Complete Form 656 and choose your payment structure

• Lump-sum cash: 20% of the offer goes in with the application; the rest in five or fewer payments after acceptance.
• Periodic payment: you start the proposed monthly payments when you file and keep paying while the IRS evaluates.

Note the form choice: Form 656 covers doubt-as-to-collectibility and effective-tax-administration offers. If your case is that you don't actually owe the tax, that's a doubt-as-to-liability offer on Form 656-L, a different track entirely.

Step 5: The fee and the initial payment

The application requires a $205 application fee plus the initial payment for your chosen structure, both non-refundable (payments apply to your debt even if the offer fails). If your income falls under the Low-Income Certification thresholds in the Form 656-B booklet, both the fee and the up-front payments are waived; you check the certification box on the form.

Step 6: Mail it and stay compliant while it's pending

The complete package (Form 656, Form 433-A (OIC), attachments, fee and initial payment) goes to the processing address in the Form 656-B booklet for your state. While the offer is pending:

• Collections generally pause: a processable offer stops new levies while it's evaluated.
• Keep filing everything on time and keep paying current-year estimates. Falling out of compliance kills a pending offer.
• Expect months, commonly six to twelve, sometimes more. If the IRS makes no determination within 24 months, the offer is deemed accepted by law.

Step 7: After the decision

Accepted: pay per the terms, and stay perfectly compliant for the next five years. Break that condition and the original debt can come back. Rejected: you generally have 30 days to appeal on Form 13711, or you can revise and resubmit, or pivot to an installment agreement or Currently Not Collectible status. Before you file at all, it's worth knowing the real odds; see what percentage of offers the IRS actually accepts.
