Offer in Compromise: How the IRS Calculates Your Future Income (2025)
The short answer: OIC future income is the IRS's estimate of the cash you could put toward your tax debt over a fixed window. The IRS takes your monthly disposable income — gross income minus allowable living expenses — then multiplies it by 12 for a lump sum offer or 24 for a periodic payment offer. That number is the biggest driver of your offer.
⏱ Timing that matters: the IRS uses your income and expenses as of the date you apply. If your income is about to drop or your expenses are about to rise, the month you file can change your offer amount. There is no countdown clock on a CP14 here — but once the IRS opens your case, your reported figures are locked in for that submission.
What "future income" actually means in an OIC
An Offer in Compromise lets you settle a tax debt for less than the full amount — but only when the IRS agrees it can't realistically collect the whole thing. To decide that, the IRS calculates your reasonable collection potential, or RCP. RCP has two parts: the equity in your assets, and your future income.
OIC future income is not a guess about your next raise. It's a straight formula. The IRS looks at what you earn now, subtracts the living expenses it allows, and multiplies the leftover by a set number of months. For a deeper walk-through of the whole process, see our guide on how an offer in compromise actually works.
The formula, step by step
The IRS builds your future income figure on Form 433-A (OIC), the financial statement that comes with the offer. Here's the sequence:
- Add up your average gross monthly income from every source — wages, self-employment, Social Security, pensions, rental income, and more.
- Subtract your allowable living expenses. These are capped by the IRS Collection Financial Standards, not by what you actually spend. The result is your monthly disposable income.
- Multiply your disposable income by 12 (lump sum cash offer) or 24 (periodic payment offer).
That product is the future income portion of your RCP. The IRS then adds the net value of your assets to reach your total minimum offer.
The 12x vs. 24x multiplier — why it matters
The multiplier depends on how you choose to pay, and it's one of the few levers you control:
- Lump sum cash offer: you pay in 5 or fewer installments within 5 months of acceptance. Future income is multiplied by 12.
- Periodic payment offer: you pay in 6 to 24 monthly installments. Future income is multiplied by 24.
A lump sum offer almost always produces a lower total offer because it uses the smaller multiplier — but it demands cash up front. The trade-off between the two is the heart of your OIC payment options decision, and it deserves real math before you commit.
Allowable living expenses: where most offers are won or lost
Your disposable income — and therefore your whole offer — hinges on which expenses the IRS lets you count. The IRS uses national and local Collection Financial Standards to cap categories like food, clothing, out-of-pocket health care, housing, utilities, and vehicle costs.
If you spend more than the standard on, say, housing, the extra usually isn't allowed unless you can prove it's necessary for your health, welfare, or to produce income. On the other hand, many people forget to claim expenses they're entitled to — court-ordered child support, required work tools, term life insurance, or out-of-pocket medical costs. Each allowable dollar you document lowers your disposable income and lowers your offer. Our breakdown of IRS allowable living expenses shows exactly what counts.
A worked dollar example
Say Maria owes $42,000. Here's how the IRS would size up her future income:
- Average gross monthly income: $5,000
- Allowable living expenses (housing, food, transportation, health care, taxes withheld): $4,400
- Monthly disposable income: $5,000 − $4,400 = $600
Now apply the multiplier:
- Lump sum offer: $600 × 12 = $7,200 future income
- Periodic offer: $600 × 24 = $14,400 future income
Maria also has $3,000 of net equity across a car and a bank account. So her minimum offer is roughly $10,200 as a lump sum ($7,200 + $3,000) or $17,400 as a periodic offer ($14,400 + $3,000) — against a $42,000 debt. Same person, same debt, very different offer depending on the payment route. This is exactly why the math, not a salesperson, decides your number.

Send us your income and expenses and an experienced tax professional will run the future-income math both ways — lump sum and periodic — so you know your true offer before you spend a dime applying. Free, confidential, no pressure.
How to estimate your future income before you apply
- Pull your real numbers. Average your gross monthly income over the last few months. Don't guess high or low — the IRS will verify with pay stubs and bank records.
- List your allowable expenses using the Collection Financial Standards, and add documented necessary expenses the standards don't cover.
- Subtract to find disposable income. If it's negative, an OIC may not even be the right tool — currently not collectible status might fit better.
- Multiply by 12 and by 24 to see both offer paths.
- Add your net asset equity to get your minimum offer, then complete Form 433-A (OIC) carefully — every figure must match your documents.
One honest warning: anyone promising to "settle for pennies on the dollar" before they've reviewed your income, expenses, and assets is selling you something. The future-income formula doesn't bend to marketing — it bends to documented dollars. The official program details are on the IRS Offer in Compromise page.
OIC future income, answered
What is future income in an Offer in Compromise?
Future income is the IRS's estimate of the cash you could put toward your debt over a set number of months. It starts with your monthly disposable income — gross income minus allowable living expenses — then multiplies that number by 12 for a lump sum offer or 24 for a periodic payment offer.
How does the IRS calculate monthly disposable income for an OIC?
The IRS takes your average gross monthly income from all sources and subtracts your allowable living expenses. Those expenses are capped by the IRS Collection Financial Standards for things like food, clothing, housing, utilities, and transportation, not by what you actually spend. Whatever is left over each month is your disposable income.
Why is my OIC offer amount higher than my disposable income?
Because the offer is not one month of disposable income — it is your future income plus the equity in your assets. Future income alone multiplies your monthly disposable income by 12 or 24. Then the IRS adds the net realizable value of your home equity, vehicles, bank accounts, and retirement accounts to reach your total reasonable collection potential.
Does the IRS use my actual expenses or its own standards?
Mostly its own. The IRS uses national and local Collection Financial Standards to cap food, housing, utilities, and transportation. If your real spending is higher, the extra usually is not allowed unless you can prove it is necessary for your health, welfare, or the production of income.
Can I lower the future income part of my offer?
Sometimes. Documenting allowable expenses you forgot to claim, such as out-of-pocket medical costs, court-ordered payments, or required work expenses, lowers your disposable income and your offer. Choosing the lump sum option uses the 12-month multiplier instead of 24. An experienced tax professional can model both before you file.
