IRS Form 656 Instructions for Offer in Compromise

IRS Form 656 instructions come down to this: before you fill in the form, confirm you’re eligible, pick the right legal basis, and calculate an offer amount the IRS will actually consider. The form itself is short. What surrounds it — a Collection Information Statement, supporting documents, a $205 fee, an initial payment, and an offer figure that meets or exceeds what the IRS thinks it could collect from you — is where applications succeed or get sent back unread.¹

Confirm You’re Eligible Before You Start

The IRS will return your application without reviewing it if any of these conditions aren’t met, and none of them have to do with how much you can afford to pay:¹

All required federal tax returns are filed. Miss one, and the IRS sends the package back and keeps your initial payment.
You’ve received a bill for at least one assessed tax debt. You can’t compromise a liability the IRS hasn’t yet assessed.
Your estimated tax payments for the current year are current.
If you have employees, your federal tax deposits are current for the current quarter and the two preceding quarters.
You are not in an open bankruptcy proceeding.

Before you invest hours in the package, run your numbers through the IRS Offer in Compromise Pre-Qualifier at irs.treasury.gov/oic_pre_qualifier. It isn’t binding, but it will tell you whether your basic financial picture supports an offer and produce a preliminary figure to aim at.²

Pick the Right Legal Basis

Section 2 of Form 656 asks which legal ground your offer rests on, and your financial statement has to be consistent with the answer.³

Doubt as to Collectability is the ground for nearly every Form 656 filing. It applies when your assets and future income can’t cover the full liability within the IRS’s remaining collection period, generally ten years from assessment.⁴

Effective Tax Administration is a narrow ground for taxpayers who technically could pay in full but for whom collection would cause severe economic hardship or be fundamentally unfair given exceptional circumstances such as serious illness or disability.⁴

A third ground, Doubt as to Liability, exists for situations where you dispute that you owe the tax at all — but it goes on Form 656-L, not Form 656, and follows a different process.⁵ If your issue is whether the tax was correctly assessed, stop here and pull the -L version.

Calculate Your Minimum Offer Amount

For a Doubt as to Collectability offer, the IRS won’t accept less than your Reasonable Collection Potential (RCP). Offering below this number almost guarantees rejection, so calculate it before you write anything in Section 3.⁴

RCP has two parts. The first is net asset equity. The IRS values most assets at 80% of fair market value (its “quick sale value”) and then subtracts what you owe against each one.⁶ A home worth $200,000 with a $150,000 mortgage produces $10,000 of equity: $160,000 minus $150,000.

The second part is future income: your monthly income minus your allowable monthly expenses, multiplied by 12 months for a lump sum offer or 24 months for a periodic payment offer. If your remaining collection period is shorter than 12 or 24 months, the IRS uses whatever’s left.⁶

Add the two together. With $10,000 in net equity and $500 of monthly disposable income, a lump sum offer needs at least $16,000 and a periodic payment offer at least $22,000.

Prepare the Collection Information Statement

The RCP calculation has to be documented, and that documentation is Form 433-A (for wage earners and self-employed individuals) or Form 433-B (for businesses).⁷ If you’re filing both an individual and a business offer, each needs its own Form 656.¹

Income

Document every source of household income for the three most recent months: pay stubs, 1099s, Social Security benefit statements, rental income, and any other regular receipts. An examiner will cross-check against public records, so omissions don’t help you — they get flagged.

Assets

List real estate, vehicles, bank accounts, investment accounts, retirement accounts, and life insurance policies with a cash surrender value. Real estate needs a current appraisal or comparable market analysis, plus documentation of mortgages and liens. Retirement accounts get disclosed even though special rules govern how much of their value counts. A life insurance policy’s cash surrender value minus any policy loans lands in the asset column.⁸

Expenses

Your monthly expenses aren’t what you actually spend. They’re capped by the IRS Collection Financial Standards, and you generally get the lesser of what you spend or what the standard allows.⁹ For food, clothing, and other national-standard categories, you get the standard amount for your family size without needing receipts.¹⁰ Housing and utility allowances vary by county. The IRS postponed the usual April 2025 update, so the standards published on April 21, 2025 remain in effect until June 2026.¹¹ Higher actual expenses can be allowed, but you’ll need to document why the standards leave you unable to meet basic needs.

Complete Form 656 Section by Section

Section 1 identifies the specific liabilities you want to compromise. List each tax form (for example, Form 1040) with the corresponding period. Multiple years get listed separately; don’t lump them together.

Section 2 is your legal basis: Doubt as to Collectability, Effective Tax Administration, or both. Whatever you check has to line up with the financial picture in Form 433-A or 433-B. If your Collection Information Statement shows you can pay in full and you claim Doubt as to Collectability, the offer contradicts itself.

Section 3 is your offer amount and payment terms. The number has to reconcile with your RCP. Below RCP, expect rejection; well above RCP, you’re overpaying without reason.

Sections 4 through 10 are the terms of the agreement. Sign and date every required line. An unsigned Form 656 gets returned unprocessed.

Choose Lump Sum or Periodic Payment

Payment terms in Section 3 affect the future-income multiplier in your RCP, the money you send with the application, and what you have to do while the IRS reviews the offer.³

Lump Sum Cash Offer

You pay the accepted amount in five or fewer installments within five months of acceptance. With the application, send 20% of the total offer as a nonrefundable upfront payment; the IRS keeps it and applies it to your tax debt whether or not the offer is accepted.⁴ The RCP uses a 12-month future income multiplier, so the minimum offer is typically lower than the periodic option.

Periodic Payment Offer

You spread the accepted amount over 6 to 24 monthly installments. Send your first proposed monthly installment with the application, and keep making the proposed monthly payments during the entire review period. Miss one, and the IRS can treat the offer as withdrawn.³ The 24-month multiplier makes the minimum offer higher, but the monthly cash flow can be easier to carry.

Low-Income Certification

If your adjusted gross income on your most recent return, or your household’s monthly gross income from Form 433-A multiplied by 12, is at or below certain thresholds, low-income certification waives both the $205 application fee and the initial payment.¹² For 2026, the thresholds in the 48 contiguous states are $37,650 for a single person, $51,100 for a family of two, $78,000 for a family of four, and an additional $13,450 for each person beyond eight. Alaska and Hawaii have higher figures. Business entities other than sole proprietorships don’t qualify.¹³

Know What You’re Agreeing to When You Sign

Two provisions in the offer terms surprise more taxpayers than any others.

Filing the offer suspends the IRS’s ten-year collection statute. The clock stops while the offer is pending, stays paused for 30 days after a rejection, and continues paused throughout any appeal.¹⁴ A rejected offer that took a year to review effectively extended the IRS’s collection window by that year. If your collection statute is close to expiring, an OIC may work against you.

The IRS keeps any refund otherwise due for periods assessed before acceptance and applies it to the debt. You also agree not to file amended returns for the tax years listed on the form while the offer is pending or after it’s accepted.¹³

Mail the Complete Package to the Right Center

A complete submission includes Form 656, the appropriate Form 433, all supporting financial documentation, the $205 application fee (unless you certify low-income), and your initial payment. Make checks payable to “United States Treasury.”

Which processing center you use depends on your state:¹³

Memphis IRS Center COIC Unit, P.O. Box 30803, AMC, Memphis, TN 38130-0803 — Arizona, California, Colorado, Georgia, Hawaii, Idaho, Kentucky, Louisiana, Mississippi, New Mexico, Nevada, Oklahoma, Oregon, Tennessee, Texas, Utah, and Washington.
Brookhaven IRS Center COIC Unit, P.O. Box 9007, Holtsville, NY 11742-9007 — all other states, the District of Columbia, Puerto Rico, and foreign addresses.

Mail to the wrong center and you risk a delay or a procedural rejection. Use certified mail with return receipt so you can prove the mailing date.

What Happens After You File

The IRS sends an acknowledgment letter confirming the offer has been accepted for processing. From that point on, the agency generally cannot levy your property or garnish your wages while the offer is pending.¹⁴ An examiner will verify your figures against public records and your supporting documents and will contact you for clarifications. Respond quickly; delays on your side stretch out the review and read as noncooperation. Most offers take several months. If you filed a periodic payment offer, keep making those monthly payments throughout.

The Five-Year Compliance Period After Acceptance

Acceptance is a binding contract. For five years from the acceptance date, you must file every required federal return on time and pay every federal tax owed in full.¹⁵ You also can’t request an installment agreement or submit another offer for any liability during that window.¹³

This is where accepted offers most often unravel. One late return or missed payment can trigger default. The IRS sends a notice of intent to terminate; if you don’t cure it, the original debt is restored in full, the interest that would have accrued is added back, the payments you already made are kept and applied to the restored balance, and collection resumes on what’s left. The compliance flags are automated, so treat every filing deadline in those five years as non-negotiable.

If Your Offer Is Rejected

You have 30 days from the date on the rejection letter to appeal to the Independent Office of Appeals, using Form 13711 or a written letter explaining the disagreement, mailed to the office that issued the rejection.¹⁶ The collection suspension continues through the appeal. Miss the 30-day window and your only remaining route is a brand-new application with a fresh $205 fee and initial payment.
