I'm Darrin Mish. For 32 years I've practiced federal tax litigation — routine audits, Tax Court cases, and everything in between. If you're facing an IRS issue, here's what you need to know first.
The “Pennies on the Dollar” Promise Is Mostly False
You have seen the commercials. “Settle your IRS debt for pennies on the dollar.” “We resolved $100,000 for $4,000.” Real-sounding testimonials. Aggressive guarantees.
Here is the truth from the IRS’s own published statistics.
In fiscal year 2024, taxpayers submitted 33,591 Offers in Compromise. The IRS accepted 7,199 of them. That is an acceptance rate of about 21.4%. Of the offers that get accepted, the average settlement is meaningful but not “pennies on the dollar” for most people. It is whatever the IRS calculates the taxpayer can realistically pay.
After 32 years of working OIC cases, I can tell you what actually qualifies a taxpayer for an Offer in Compromise, how the IRS does the math, and why the national marketing firms either lie about this or quietly let unrealistic cases die without filing.
If you are considering an OIC, here is what determines whether you actually qualify.
What an Offer in Compromise Actually Is
Under Internal Revenue Code Section 7122, the IRS has authority to settle federal tax debt for less than the full amount when one of three conditions is met:
Doubt as to Collectibility (DATC): The IRS doubts they can collect the full amount within the remaining time on the 10-year Collection Statute Expiration Date.
Doubt as to Liability (DATL): The IRS doubts the underlying tax assessment is correct.
Effective Tax Administration (ETA): Collecting the full amount would create economic hardship or would be inequitable under the specific facts of the case.
The vast majority of accepted OICs are Doubt as to Collectibility offers. DATL and ETA cases exist but are rare and require specific circumstances.
For most taxpayers wondering “will I qualify,” the real question is whether they meet the math for Doubt as to Collectibility.
The RCP Formula: This Is the Whole Game
The IRS evaluates a DATC Offer in Compromise using a formula called Reasonable Collection Potential, or RCP. Your offer must equal or exceed your RCP for the IRS to accept it.
The RCP has two components:
Equity in Assets + Future Income = RCP
Both components matter. Get either one wrong and the offer gets rejected.
Component 1: Equity in Assets
The IRS calculates your “equity” in every asset you own. They start with the fair market value of each asset, subtract the secured debt against it, and apply specific haircuts based on IRS internal guidelines.
Real Estate
Fair market value minus mortgage balance minus an 80% liquidation discount. So if your home is worth $400,000 and you owe $250,000 on the mortgage, your equity for OIC purposes is ($400,000 – $250,000) * 0.80 = $120,000.
Vehicles
Fair market value minus loan balance minus 80% discount. For each vehicle except one (the IRS allows a personal vehicle exemption of around $3,450 in current standards).
Bank Accounts
Generally 100% of the balance. The IRS does not haircut cash.
Retirement Accounts
Generally 70-100% of the balance, depending on whether the taxpayer needs the funds for necessary living expenses (IRM 5.8.5 governs this analysis).
Other Assets
Everything you own gets valued. Investment accounts, business interests, life insurance cash value, collectibles, jewelry above a small exemption, anything else with meaningful value.
Total Equity
Add up the post-haircut equity in everything. This is the asset component of your RCP.
Component 2: Future Income
This is where most taxpayers get tripped up. The IRS does not just look at what you own. They look at what you can pay from future earnings.
The formula:
Monthly Income – Allowable Monthly Expenses = Remaining Monthly Income
Then the Remaining Monthly Income gets multiplied by either:
12 months if you are submitting a lump-sum offer (paid within 5 months of acceptance).
24 months if you are submitting a periodic payment offer (paid over 6 to 24 months).
This multiplier is the single most important variable in an OIC. A taxpayer with $1,000 remaining monthly income has $12,000 in future income for a lump sum offer and $24,000 for a periodic offer. The choice between these structures matters.
What Counts as “Allowable” Expenses
The IRS does not let you deduct whatever you actually spend. They use published National Standards and Local Standards.
National Standards cap food, clothing, housekeeping, personal care, and miscellaneous expenses at amounts based on family size. These are typically lower than what most households actually spend.
Local Standards cap housing and utilities based on your county, and transportation based on your region. If your actual rent is higher than the Local Standard, the IRS will only allow the Local Standard.
Necessary Expenses include things like child care, court-ordered payments, health insurance, and out-of-pocket medical costs. These are allowed if reasonable and substantiated.
Not Allowed: college tuition you are paying for adult children, voluntary retirement contributions beyond minimums, charitable contributions, payments on credit card debt (in most cases), payments on auto loans for second vehicles, and many other categories that taxpayers often consider necessary.
The gap between actual household spending and IRS-allowable expenses is what creates Remaining Monthly Income on paper even when families feel like they have nothing left at the end of the month.
Putting the Formula Together
A simple example.
A Tampa taxpayer owes $80,000 to the IRS. They have $25,000 of equity in their home after the 80% haircut, $3,000 in a checking account, and $2,000 in a paid-off car (after the personal vehicle exemption). Their total asset equity is $30,000.
Their monthly take-home pay is $5,500. The IRS allowable expenses for their family size and Tampa Bay location come to $5,200. Remaining Monthly Income is $300 per month.
For a lump-sum offer: $300 * 12 = $3,600 future income component.
For a periodic offer: $300 * 24 = $7,200 future income component.
Lump-sum RCP: $30,000 + $3,600 = $33,600.
Periodic RCP: $30,000 + $7,200 = $37,200.
This taxpayer would need to offer $33,600 as a lump sum (paid within 5 months) or $37,200 over 6 to 24 months to have a realistic shot at acceptance.
That is the math. It is not arbitrary, it is not negotiable in the way most people expect, and it is heavily formula-driven.
What Disqualifies You From an OIC
Even if your RCP math looks favorable, certain conditions disqualify you.
Unfiled tax returns. The IRS will not consider any OIC if you have any tax returns unfiled. You must be in full filing compliance.
Active bankruptcy. OICs cannot be considered while you are in bankruptcy. The bankruptcy court handles tax debt issues in that proceeding.
Not current with estimated taxes. If you are self-employed and not making current estimated tax payments, your OIC will not be considered.
Not current with payroll deposits. Business owners must be current on federal tax deposits for any active business.
Prior OIC default. If you have had a previous OIC accepted and then defaulted on the terms, your subsequent OIC will face significant hurdles.
The math does not work. This is the most common disqualification. If your RCP exceeds the tax debt or comes close to it, the IRS will tell you to set up an installment agreement instead.
The Forms and Fees
The OIC application package includes:
Form 656 – the offer itself.
Form 433-A (OIC) – financial information for individuals.
Form 433-B (OIC) – financial information for businesses.
Supporting documentation – typically 60 to 100 pages of bank statements, pay stubs, asset valuations, expense documentation.
$205 application fee.
Initial offer payment.
The initial offer payment depends on the structure:
Lump-sum offer: 20% of the offer amount.
Periodic offer: the first monthly installment.
Both the application fee and the initial payment are non-refundable. If your offer is rejected, the IRS keeps both. They apply the initial payment toward your tax debt (so it is not wasted), but the application fee is gone.
Low-Income Certification
If your income qualifies, the IRS waives both the application fee and the initial payment requirement. You qualify if your adjusted gross income from the most recent return, OR your household’s gross monthly income times 12, falls at or below 250% of the federal poverty guidelines.
For a family of three in 2026, this threshold is around $65,000. For a family of four it is around $78,000. Check the current Form 656 instructions for the exact numbers.
The 5-Year Compliance Requirement
If your OIC gets accepted, you agree to remain in full tax compliance for five years afterward. This means:
Filing all required returns on time.
Paying all taxes owed in full as they come due.
Not incurring any new tax debt.
If you default on this five-year compliance, the IRS can rescind the OIC, reinstate the full original tax debt, and add any new tax debt on top of it.
This is the part the national firms do not emphasize. They tell you about the front-end savings without explaining that maintaining post-acceptance compliance is harder than it sounds for taxpayers who landed in tax debt in the first place.
The Acceptance Process
Once you submit a complete OIC package, the case goes to the IRS Centralized Offer in Compromise unit. The process typically takes 6 to 12 months for an initial decision.
The COIC examiner reviews your financial documentation, verifies your numbers against IRS records, may request additional information, and ultimately recommends acceptance, rejection, or a counteroffer.
If accepted, you pay the remaining offer amount according to the terms you selected. The IRS releases any tax liens (after the offer is fully paid), removes the tax debt from your account, and the five-year compliance period begins.
If rejected, you have appeal rights.
What to Do If Your Offer Is Rejected
A rejected OIC is not the end. You can request an appeal with the IRS Office of Appeals within 30 days of the rejection letter. The appeals officer reviews the case independently and often takes a more flexible view than the COIC examiner did.
Many rejected offers get accepted on appeal, particularly if the rejection was based on disputed allowable expenses or asset valuations. The appeals process adds another 6 to 12 months but the success rate at appeals is meaningful.
If the appeal also fails, you can either submit a new OIC (with different terms or improved documentation) or pursue a different collection alternative like Currently Not Collectible status or a Partial Payment Installment Agreement.
When an OIC Is Actually the Right Move
After working thousands of these cases, the taxpayers who tend to be good OIC candidates share certain features:
Limited equity in assets, often because they rent or have minimal home equity.
Income that barely covers IRS-allowable expenses, leaving little Remaining Monthly Income.
Older tax debts where the 10-year CSED is approaching.
No realistic path to paying the full debt within the remaining collection period.
A stable enough financial situation that they can maintain the five-year compliance requirement.
The taxpayers who are NOT good OIC candidates:
People with significant home equity.
High-income earners who happen to be temporarily cash-poor.
Recent tax debt (less than two years old in most cases).
Self-employed taxpayers who have not been keeping up with estimated payments.
Anyone whose financial situation is likely to improve dramatically in the next few years.
The Bottom Line
An Offer in Compromise is a real IRS program with real benefits for the right taxpayer. It is not a magic eraser. It is a math-based settlement program that requires specific financial conditions, complete compliance, and the ability to maintain compliance for five years afterward.
About one in five offers gets accepted. The ones that do are usually well-prepared submissions for taxpayers whose RCP math genuinely supports a settlement. The ones that get rejected are typically submitted by national firms that promised acceptance regardless of qualifications, or by taxpayers who ran the math without understanding what the IRS considers an “allowable expense.”
If you are considering an Offer in Compromise, the honest first step is running the RCP calculation. Do that before you write a check to anyone promising to settle your debt.
