Offer in Compromise Payment Options: Lump Sum vs. Periodic (2026)

What an Offer in Compromise actually is

An Offer in Compromise (OIC) is an agreement that settles your tax debt for less than the full amount you owe. The IRS only accepts one when it concludes it likely can't collect the full balance before the 10-year collection statute runs out. It is real — but it is not the "pennies on the dollar" fantasy you hear on the radio. Anyone promising to settle your debt for pennies on the dollar before reviewing your finances is selling you something.

Before you ever get to choose a payment option, the IRS calculates your "reasonable collection potential" — basically, what they think they could squeeze out of you. That number sets your minimum offer amount. The payment option you pick then changes how that number is calculated and how fast you have to come up with the money. You report all of this on Form 656 and the Form 433-A (OIC).

The two offer in compromise payment options, side by side

When you file Form 656, you choose one of two ways to pay. Here is how each one works.

Option 1: Lump sum cash

• You send 20% of your total offer amount with the application. This down payment is nonrefundable.
• If the IRS accepts, you pay the remaining 80% in five or fewer payments, all within 5 months of the acceptance date.
• Your offer amount uses your monthly disposable income multiplied by 12 — a smaller multiplier, so the total is usually lower.

Option 2: Periodic payment

• You send your first proposed monthly payment with the application.
• You keep making those monthly payments while the IRS reviews your offer — which can take many months. Stop paying and the offer is returned.
• Once accepted, you finish paying over 6 to 24 months.
• Your offer amount uses your monthly disposable income multiplied by 24 — a larger multiplier, so the total is usually higher.

Both options also require a one-time application fee (currently $205) unless you qualify as low-income. The full rules are on the IRS Offer in Compromise page.

A worked example: why the choice changes your number

This is the part most people miss. The payment option you pick literally changes the dollar amount you offer. Here's a simplified example.

Say the IRS figures you have $5,000 of equity in assets (a car, some savings) and $300 of monthly disposable income after allowable living expenses.

• Lump sum cash offer: $5,000 + ($300 × 12) = $8,600. You'd send 20% — about $1,720 — with the application, then pay the remaining $6,880 within five months of acceptance.
• Periodic payment offer: $5,000 + ($300 × 24) = $12,200, paid in monthly installments over up to two years.

Same taxpayer, same debt — but the lump sum offer is $3,600 lower. The catch: you need access to roughly $8,600 in cash within months. The periodic option costs more but lets you pay from income over time. There's no universally "right" answer — it depends on whether you can raise the cash. A close cousin of this calculation drives a partial payment installment agreement, which is sometimes a better fit when you can't fund a lump sum.

What happens if you pick the wrong option

An OIC is not a casual application. Choosing badly costs you real money and time. Here's how it typically goes wrong:

1. You pick periodic but can't keep up the payments. The IRS returns your offer with no appeal rights — and every payment you already made is gone, applied to your debt.
2. You pick lump sum but can't raise the cash in five months. If you default after acceptance, the IRS keeps your payments and the full original balance (minus what you paid) comes roaring back, with penalties and interest still running.
3. Your offer is too low and gets rejected. Your application fee and down payment are nonrefundable. You can appeal, but you've lost months — and during that time, interest kept compounding.
4. You should have filed something else entirely. Many people who think they need an OIC actually qualify for a streamlined plan or hardship status faster and cheaper. See payment plan vs. offer in compromise before you commit.

One bright spot: while your OIC is pending, the IRS generally pauses new levy action, and the 10-year collection clock is tolled (paused) while it reviews.

How to choose and file, step by step

1. Confirm you're a real candidate first. Use the IRS Offer in Compromise Pre-Qualifier tool for a rough check. You must have filed all required returns and not be in an open bankruptcy.
2. Build your reasonable collection potential. Add up asset equity and your monthly disposable income after IRS allowable living expenses. This is the number that decides everything.
3. Run both payment options. Calculate the lump sum total (income × 12) and the periodic total (income × 24). Be honest about whether you can fund the lump sum within five months.
4. Pick the option you can actually complete. A lower offer you can't pay is worse than a higher offer you can.
5. File Form 656 with Form 433-A (OIC), your fee or low-income certification, and your first payment. Keep copies of everything.
6. Get a professional review if you owe a lot. When the balance is large or your finances are complicated, a second set of eyes before you file can save you the nonrefundable money you'd otherwise lose on a bad offer.
