An Offer in Compromise (OIC) is a settlement where you pay less than you owe. You might owe $15,000 but settle for $3,000. The IRS accepts roughly 25% of OIC applications each year, so this isn't a given—but it's possible if you meet criteria.
Who qualifies: You must demonstrate genuine financial hardship. The IRS uses a formula comparing your monthly income to necessary living expenses (rent, food, utilities, transportation, insurance). If there's no "reasonable ability to pay" after essentials, an OIC is viable.
The formula: The IRS calculates your "reasonable collection potential" (RCP). They assess 12 months of future income minus living costs, plus 20% of your liquid assets. If RCP is lower than your tax debt, they consider settlement.
Real example: You owe $20,000 in back taxes. Monthly income: $2,500. Monthly expenses (verified): $2,200 (rent $1,200, food $400, utilities $200, car payment $300, insurance $100). Surplus: $300/month. Over 12 months, that's $3,600. The IRS might accept a $4,500 offer (slightly above calculated ability) and forgive the rest.
Application process: File Form 656 with Form 433 (financial statement). Include 2-3 months of pay stubs, bank statements, and proof of expenses. Fee: $225 (non-refundable). Processing takes 6-24 months.
Critical detail: Submission puts collections on hold, but you must remain in compliance (file all returns, pay current taxes). If accepted, the settlement amount is fixed and due within 24 months.
