Offer in Compromise (OIC): The Complete Guide

An Offer in Compromise (OIC) lets you settle your IRS tax debt for less than you owe. In 2023, the IRS accepted about 30% of all OIC applications — roughly 13,000 offers. It’s not a loophole or a scam: it’s a real IRS program designed for people who genuinely cannot pay their full tax debt. Before you read further, use our free OIC pre-qualifier calculator to see whether you’re likely to qualify.

What Is an Offer in Compromise?

An Offer in Compromise is a formal agreement between you and the IRS to settle your tax liability for less than the full amount you owe. The IRS accepts an OIC when it concludes that collecting the full amount is unlikely — either because you don’t have enough assets or income to pay it (Doubt as to Collectibility), or because doing so would create serious economic hardship even if technically possible (Effective Tax Administration).

The IRS doesn’t accept OICs as a favor. It accepts them when its own math shows it won’t collect much more from you anyway. The key number is your Reasonable Collection Potential (RCP) — the maximum the IRS believes it can realistically recover from you. If your offer meets or exceeds that number, you have a legitimate chance at acceptance.

Who Qualifies for an OIC?

The IRS has hard eligibility rules. You must meet all of the following:

1. Filed all required tax returns — The IRS will not consider your offer if any returns are missing. File them first, even if you can’t pay.
2. Not in an active bankruptcy proceeding — If you’re in Chapter 7 or Chapter 13, you cannot submit an OIC until the bankruptcy case is closed.
3. Made all required estimated tax payments — If you’re self-employed, you must be current on quarterly estimated taxes for the current year.
4. Explored other payment options — The IRS expects applicants to have considered standard installment agreements first. If you can pay in full within 6 years, the IRS is unlikely to accept an OIC.

Beyond the eligibility rules, approval depends on your financial picture. The IRS looks at:

• Income: Monthly gross income from all sources
• Allowable expenses: The IRS uses its own National Standards (not your actual budget) to determine what living expenses it considers reasonable
• Assets: Equity in real estate, vehicles, bank accounts, retirement accounts, and other property
• Future earning potential: If you’re young and have professional skills, the IRS may project higher future income

Use our OIC pre-qualifier calculator to estimate whether your situation is likely to meet the IRS threshold before spending time on the full application.

How the IRS Calculates Your Offer Amount (RCP)

This is the most important section in this guide. The IRS doesn’t negotiate based on how much you owe — it calculates the minimum it will accept based on what it thinks it can realistically collect from you. That number is your Reasonable Collection Potential (RCP).

The formula:

RCP = Net Assets + Future Income

Net Assets = the equity the IRS can liquidate from your property:

• Equity in your home (current value minus mortgage)
• Bank and investment account balances
• Vehicle equity (current value minus loan)
• Retirement accounts — the IRS counts 80% of the value (discounted for early withdrawal taxes and penalties)
• Business assets, jewelry, collectibles

Future Income = your monthly disposable income × a multiplier:

• Lump-sum (cash) offer: 12 months of disposable income
• Periodic payment offer: 24 months of disposable income

Disposable income = monthly gross income minus IRS-allowed living expenses. The IRS uses its National Standards for food, clothing, housing, transportation, and health care — not your actual bills. If your actual rent is higher than the IRS standard for your area, the IRS may not allow the full amount.

Worked example:

Say you earn $3,500/month, and after applying IRS National Standards your allowable monthly expenses are $3,100. Your disposable income is $400/month. You have $5,000 in a savings account and no significant other assets.

• Lump-sum offer (12-month multiplier): ($400 × 12) + ($5,000 × 80%) = $4,800 + $4,000 = $8,800 minimum offer
• Periodic payment offer (24-month multiplier): ($400 × 24) + ($5,000 × 80%) = $9,600 + $4,000 = $13,600 minimum offer

If you owed $60,000, you could potentially settle the entire debt for $8,800 to $13,600 — depending on which payment option you choose.

Lump-Sum vs Periodic Payment OIC

When you submit an OIC, you choose one of two payment structures:

Lump-Sum (Cash Offer)

• Pay your full offered amount within 5 months of IRS acceptance
• Requires a nonrefundable 20% down payment when you submit your application
• Uses a 12-month multiplier for future income — resulting in a lower minimum offer
• Best for: people who can access a lump sum (savings, family loan, retirement withdrawal) and want to minimize the total offer amount

Periodic Payment Offer

• Pay your offered amount in monthly installments over 6 to 24 months
• No 20% down payment required at submission — you start with your first monthly payment
• Uses a 24-month multiplier for future income — resulting in a higher minimum offer
• You must continue making monthly payments throughout the IRS review period (even before acceptance)
• Best for: people without savings or access to a lump sum

The math favors the lump-sum option (lower total offer), but the 20% down payment is a real obstacle for many people. If you genuinely cannot afford 20% upfront, the periodic payment option is your path.

The 20% Nonrefundable Down Payment — Read This Carefully

Many people are blindsided by this requirement. When you submit a lump-sum OIC using Form 656, you must include a 20% nonrefundable payment with your application.

If the IRS accepts your offer, that 20% goes toward your settlement amount.

If the IRS rejects your offer, that 20% is gone. You do not get it back.

This is not a mistake in the rules — it’s intentional. The IRS uses this requirement to discourage frivolous low-ball offers. Before submitting a lump-sum OIC, make sure your offered amount is realistic based on your RCP calculation. Submitting a $500 offer on a $50,000 debt when the IRS calculates your RCP at $12,000 will cost you $100 (20% of $500) and accomplish nothing.

If you cannot afford the 20% down, two options exist: (1) submit a periodic payment OIC instead, or (2) request a fee waiver if your household income is at or below 250% of the federal poverty level.

What Happens After You Submit

Once you submit your OIC package — Form 656, Form 433-A, the $205 application fee, and your initial payment — the IRS review process begins:

1. Initial processing (4–8 weeks): The IRS confirms your application is complete and assigns it to an OIC examiner.
2. Financial review (3–6 months): The examiner reviews your Form 433-A, verifies your income, assets, and expenses, and may request additional documentation (bank statements, pay stubs, property records).
3. Decision: The IRS accepts, rejects, or issues a counter-offer. A counter-offer typically requests a higher amount based on their RCP calculation.

Important things that happen during IRS review:

• Collection is paused. The IRS cannot levy your wages or bank accounts while your OIC is under review.
• Interest and penalties keep accruing. Your total balance grows while the IRS reviews your offer. This doesn’t affect your offer amount, but it matters if you’re rejected.
• The 10-year collection clock (CSED) is tolled. The statute of limitations on IRS collection is paused for the duration of the review plus 30 days.

If the IRS issues a counter-offer, you can accept it, reject it, or negotiate further. You are not obligated to accept a counter-offer.

Common Rejection Reasons

Most OIC rejections fall into one of these categories:

• Offer too low — Your proposed amount is below what the IRS calculated as your RCP. The fix: recalculate using the correct formula, or submit the periodic payment option to lower the required down payment.
• Unfiled tax returns — The IRS will automatically reject your application if any required returns are missing. File them before submitting.
• Active bankruptcy — OICs cannot be processed while you’re in bankruptcy.
• Failure to provide documentation — If the IRS requests additional information and you don’t respond, your offer is rejected.
• Income or assets suggest ability to pay in full — If your RCP calculation shows you can pay the full balance through an installment agreement, the IRS will reject the OIC and direct you to an installment agreement instead.

If Your OIC Is Rejected

Rejection is not the end. You have 30 days from the date of the rejection letter to appeal to the IRS Independent Office of Appeals. An appeals officer will independently review your financial information and the examiner’s rejection.

If the appeal is unsuccessful, your options are:

• Resubmit a revised OIC with a higher offer amount or additional documentation
• Set up an installment agreement to pay over time
• Apply for Currently Not Collectible status if your income doesn’t cover basic expenses
• Request penalty abatement to reduce the total amount owed

DATC vs ETA Offers — The Two Types of OIC

The standard OIC most people are aware of is called a Doubt as to Collectibility (DATC) offer. This is the one described throughout this guide — you cannot pay your full tax debt based on your income and assets.

There is a second, less common type: Effective Tax Administration (ETA). An ETA offer is for taxpayers who could technically pay their full tax debt but doing so would cause severe economic hardship or would be fundamentally unfair given the circumstances. For example: an elderly taxpayer on a fixed income whose only asset is the home they live in. ETA offers require additional documentation and are evaluated on equity and public policy grounds, not just the RCP formula.

Most applicants submit DATC offers. A third, rarer category is Doubt as to Liability (DATL) — for taxpayers who believe the assessed tax itself is wrong and who file Form 656-L, Offer in Compromise (Doubt as to Liability) instead of the standard Form 656. If you believe your situation might qualify for an ETA or DATL offer, consider consulting a tax professional before applying.

How to Apply

Applying for an OIC requires careful preparation. Submitting an incomplete or inaccurate package wastes months and money.

1. Check eligibility using our OIC pre-qualifier calculator — takes 5 minutes and tells you whether your situation is likely to qualify before you commit to the process.
2. Complete Form 433-A (Collection Information Statement for Wage Earners and Self-Employed Individuals) — this is your full financial disclosure: income, expenses, assets, and liabilities. Accuracy here is critical. Understating income or assets is tax fraud.
3. Complete Form 656 (Offer in Compromise application) — lists the tax periods covered, your offered amount, and the payment option (lump-sum or periodic).
4. Pay the $205 application fee — waived for applicants at or below 250% of the federal poverty level (check the fee waiver box on Form 656).
5. Include your initial payment:
   • Lump-sum: 20% of your offered amount
   • Periodic: first month’s installment payment
6. Submit to the IRS — mail to the address listed in the Form 656 instructions for your state.
7. Stay compliant while under review — continue filing returns on time and making any required estimated tax payments. If you fall out of compliance during review, your OIC will be returned.

Processing typically takes 6–12 months. During that time, do not miss any estimated tax deadlines and respond promptly to any IRS documentation requests.
