Offer in Compromise Calculator: Do You Qualify? (2026)

The IRS Offer in Compromise program, authorized under Internal Revenue Code § 7122, allows qualifying taxpayers to settle their federal tax debt for less than the full amount owed. The IRS accepted 17,890 offers in fiscal year 2022 at an average settlement of roughly $5,240 against an average liability of $74,000, which works out to approximately 7 cents on the dollar. Understanding how the IRS calculates the minimum acceptable offer is the single most important factor in determining whether an OIC is realistic for your situation and, if so, how much you should offer.

The calculation centers on a figure called Reasonable Collection Potential. Every dollar of the formula matters because the IRS will reject any offer that falls below the computed RCP. This guide walks through the complete calculation step by step, including a worked example, so you can estimate your own offer amount before engaging with the IRS.

How Does the IRS Calculate Your Offer in Compromise?

The IRS uses a standardized formula to determine the minimum dollar amount it will accept to settle a tax debt through an Offer in Compromise. That formula is built around the concept of Reasonable Collection Potential, which the IRS defines in the Internal Revenue Manual (IRM 5.8.4) as the total amount the agency could reasonably expect to collect from a taxpayer through normal enforcement channels before the 10-year Collection Statute Expiration Date (CSED) runs out.

The RCP formula has two components. The first component is future income, calculated by determining how much disposable income you have each month after the IRS subtracts its version of allowable living expenses, then multiplying that monthly figure by either 12 or 24 depending on the payment option you choose. The second component is net realizable equity in assets, which represents the cash the IRS could generate by seizing and selling your property. Added together, these two numbers produce your RCP. Any offer you submit must meet or exceed the RCP, or the IRS will reject it.

According to IRS Data Book statistics, the agency processed approximately 46,285 OIC applications in fiscal year 2022 and accepted 38.6% of them. The high rejection rate is driven largely by applicants who offer less than their calculated RCP or who fail to meet procedural requirements. An attorney-backed tax resolution firm can help you calculate the RCP accurately and structure your offer to meet the threshold the IRS requires.

What Is Reasonable Collection Potential?

Reasonable Collection Potential is the cornerstone of every OIC evaluation. The IRS breaks it into two distinct parts and adds them together to arrive at a single dollar figure representing the floor of any acceptable offer.

Part 1: Future Income

The IRS calculates your monthly disposable income by subtracting allowable living expenses from your gross monthly income. Allowable expenses are not your actual expenses. Instead, the IRS applies standardized amounts drawn from two sources. National Standards, published annually on irs.gov, cover food, clothing, personal care, housekeeping, and out-of-pocket health care costs. These are fixed amounts based on household size. Local Standards, also published on irs.gov, set housing and utility caps by county and transportation costs by Census region and metropolitan statistical area. If your actual spending in any category exceeds the standard, you must demonstrate with documentation that the higher amount is necessary for the health, welfare, and production of income of your household.

Once the IRS arrives at your monthly disposable income, it applies an income multiplier that depends on which payment option you select. Under the Fresh Start initiative (IRS News Release IR-2012-53), lump-sum offers paid within 5 months of acceptance use a 12-month multiplier. Periodic payment offers paid over 6 to 24 months use a 24-month multiplier. Before Fresh Start, these multipliers were 48 and 60 months respectively, so the current formula is significantly more favorable for taxpayers.

Part 2: Net Realizable Equity in Assets

The second RCP component accounts for the value the IRS could recover by seizing your assets. The IRS starts with the fair market value of each asset, subtracts any outstanding loans or encumbrances, and then applies a quick-sale value discount, typically 80% of the net equity. This discount reflects the reality that forced sales rarely achieve full market value. Assets included in this calculation are real property, vehicles, bank accounts, investment accounts, retirement accounts (with adjustments), life insurance cash value, and any other property with measurable equity. IRM 5.8.5.4 details the specific valuation methods the IRS applies to each asset category.

Certain assets receive special treatment. Primary residences are subject to homestead exemption considerations in some states. Retirement accounts may be discounted further to account for early withdrawal penalties and taxes. The IRS also disregards assets needed for the production of income, such as tools of the trade, up to certain thresholds. According to Treasury Inspector General for Tax Administration (TIGTA) reports, asset valuation disputes are one of the top three reasons OIC applications stall during processing.

How Do You Calculate Your Estimated Offer Amount?

Walking through a concrete example makes the formula tangible. Consider a single taxpayer earning $80,000 per year ($6,667 gross monthly income) who owes $52,000 in federal tax debt across multiple years and wants to submit a lump-sum offer.

Step 1: Determine Monthly Disposable Income

Start with gross monthly income of $6,667. The IRS subtracts allowable expenses using the national and local standards. For a single taxpayer, the 2024 national standard for food, clothing, and other items is approximately $785 per month. The local standard for housing and utilities varies by county, but assume $1,767 for this example (a mid-range county). Transportation ownership cost is $588, and operating cost is $291. Health care out-of-pocket for taxpayers under age 65 is $75 per month. Federal, state, and local tax withholding totals approximately $1,450.

Total allowable expenses: $785 + $1,767 + $588 + $291 + $75 + $1,450 = $4,956. Monthly disposable income: $6,667 - $4,956 = $1,711. Because this is a lump-sum offer, the IRS multiplies by 12: $1,711 x 12 = $20,532 in future income.

Step 2: Calculate Net Realizable Equity in Assets

Assume the taxpayer owns a vehicle worth $18,000 with a $12,000 loan balance, a bank account with $3,200, and no real property or investment accounts. Vehicle net equity: ($18,000 - $12,000) x 0.80 = $4,800. Bank account equity: $3,200 (no discount applied to cash). Total net realizable equity: $4,800 + $3,200 = $8,000.

Step 3: Add the Components

RCP = Future Income + Net Realizable Equity = $20,532 + $8,000 = $28,532. The minimum offer the IRS would consider for this taxpayer is $28,532. On a $52,000 debt, that represents approximately 55 cents on the dollar. This taxpayer would save roughly $23,468 compared to paying in full, but the offer amount is still substantial because the income and asset profile supports collection.

If this same taxpayer chose a periodic payment offer instead, the multiplier would increase from 12 to 24 months: $1,711 x 24 = $41,064 in future income, plus $8,000 in assets, for an RCP of $49,064. At that level the OIC would save only about $3,000 and an IRS Fresh Start installment agreement might be a simpler path. This comparison illustrates why the payment option you select directly impacts whether an OIC makes financial sense.

What Is the OIC Eligibility Checklist?

Before the IRS will even evaluate your offer amount, you must satisfy a set of procedural eligibility requirements. Missing any single item results in automatic rejection and return of your application, wasting both time and the non-refundable fee. The IRS outlines these requirements in Form 656 instructions and IRM 5.8.1.

• All required tax returns filed. The IRS will not consider an OIC from a taxpayer with unfiled returns. If you have unfiled tax returns, those must be prepared and submitted before your OIC application.
• Application fee of $205. This non-refundable fee must accompany Form 656. Taxpayers whose household income falls at or below 250% of the federal poverty level qualify for a fee waiver by completing Section 1 of Form 656. According to IRS statistics, roughly 40% of OIC applicants qualify for the low-income certification.
• Initial payment. Lump-sum offers require a 20% down payment submitted with the application. Periodic payment offers require the first proposed monthly installment. Low-income certified applicants are exempt from both the fee and the initial payment under IRC § 7122(c)(2).
• Current on estimated tax payments. If you are self-employed, all required estimated tax payments for the current tax year must be current at the time of application.
• Not in open bankruptcy. Taxpayers with a pending bankruptcy case cannot submit an OIC. The Bankruptcy Code governs tax debt resolution during active proceedings, and the IRS will return any OIC application filed during this period.
• Form 433-A (OIC) or 433-B (OIC) completed. Individuals submit Form 433-A (OIC) detailing income, expenses, assets, and liabilities. Businesses use Form 433-B (OIC). These forms require supporting documentation including bank statements, pay stubs, mortgage statements, and asset valuations for the prior three months.

The IRS has the authority under Treasury Regulation § 301.7122-1 to reject an OIC for procedural deficiencies without evaluating the merits. IRS data shows that a significant percentage of initial rejections stem from incomplete applications rather than financial ineligibility. Working with a licensed tax professional backed by a law firm ensures your application package is complete and properly documented before submission.

Why Do Most OIC Applications Get Rejected?

The IRS rejected more than 61% of OIC applications processed in fiscal year 2022. Understanding the specific reasons for rejection is critical because each one is avoidable with proper preparation. IRS examiner guidance in IRM 5.8.7 outlines the evaluation criteria and common deficiency patterns.

The most common rejection reason is offering less than the calculated Reasonable Collection Potential. Many taxpayers underestimate their RCP because they use actual expenses rather than the IRS allowable standards, fail to account for asset equity the IRS would include, or apply the wrong income multiplier. The IRS does not negotiate below the RCP except in rare Effective Tax Administration cases involving documented economic hardship or exceptional circumstances under IRM 5.8.11.

Incomplete or inaccurate financial disclosures are the second leading cause of rejection. The IRS cross-references every figure on Form 433-A (OIC) against its own databases, including W-2 and 1099 records, bank account information from third parties, and property records. Any discrepancy triggers additional scrutiny and often leads to rejection. Per IRS Taxpayer Advocate Service reports, the most common discrepancies involve unreported income sources, understated asset values, and omitted bank accounts.

Procedural failures account for another significant percentage of rejections. Filing the offer while in open bankruptcy, submitting without required estimated tax payments current, omitting the $205 fee or initial payment, and having unfiled returns are all grounds for automatic return of the application without evaluation. The IRS does not issue partial rejections. If any eligibility requirement is unmet, the entire application is returned.

Finally, some taxpayers submit an OIC when a different resolution strategy would be more appropriate. If your monthly income comfortably covers full payment within the remaining collection statute, the IRS will reject the offer and direct you toward an installment agreement. Conversely, if your income and assets are essentially zero, a Currently Not Collectible designation may be a faster path to relief without the $205 fee and documentation burden. An Offer in Compromise is the right tool when you have some ability to pay but cannot cover the full balance within the CSED.
