The Number That Determines Whether the IRS Will Accept Your Offer
When you submit an Offer in Compromise based on doubt as to collectibility — the most common basis for an OIC — the IRS does not simply decide whether your offer sounds reasonable. It runs a specific mathematical calculation called the Reasonable Collection Potential, or RCP. If your offer equals or exceeds the RCP, the IRS is generally required to accept it. If it falls short, the IRS will reject the offer, regardless of how sympathetic your circumstances appear. Understanding how the RCP is calculated gives you a meaningful roadmap for structuring an offer that has a real chance of approval.
What the RCP Actually Measures
The Reasonable Collection Potential is the IRS's estimate of the maximum amount it could collect from you over the remaining life of the collection statute — that is, before the ten-year statute of limitations on collection expires. It combines two components: the net realizable value of your assets and your future income potential after subtracting allowable living expenses. The IRS adds these two numbers together to arrive at the RCP, and your offer must at minimum match this figure.
This calculation is not a vague impression of your finances. It is a structured formula applied through IRS Collection Financial Standards and your completed financial disclosure (Form 433-A for individuals, Form 433-B for businesses). Every line of that form feeds directly into the RCP calculation, which is why how you complete the financial disclosure matters enormously.
Component One: Net Realizable Value of Assets
The IRS looks at every significant asset you own and assigns it a value based on what the IRS believes it could collect — not necessarily the fair market value you might expect. For most assets, the IRS uses 80% of quick-sale value, reasoning that a forced liquidation yields less than an arms-length sale. The key asset categories are:
- Bank accounts and cash: 100% of the current balance. There is no reduction for quick-sale purposes because cash is cash.
- Real estate: The IRS uses 80% of fair market value, minus any outstanding mortgage balance. If you own a home worth $300,000 with a $250,000 mortgage, the IRS assigns an equity value of $240,000 (80% × $300,000) minus $250,000 — arriving at negative equity, which counts as zero.
- Vehicles: 80% of the loan value (Kelley Blue Book or similar) minus any outstanding loan balance.
- Investment and retirement accounts: Retirement accounts (401(k), IRA) are valued at the current balance minus early withdrawal penalties and taxes — typically resulting in a value of about 70% of the account balance. Investment accounts are valued at market value with the same 80% quick-sale haircut applied.
- Business assets: Equipment, inventory, and accounts receivable are included at 80% of fair market value.
The IRS adds up the net realizable value of all your assets to arrive at the asset component of the RCP. Assets you have recently transferred or dissipated — meaning you no longer own them but gave them away, sold them below value, or spent the proceeds — may be added back into the calculation as dissipated assets, a point that catches many taxpayers off guard.
Component Two: Future Income Potential
The second component of the RCP is your ability to pay from future income. The IRS calculates this by looking at your monthly net income — gross income minus allowable monthly living expenses — and multiplying it by a factor that depends on which payment option you choose for the offer.
Allowable living expenses are not your actual expenses. They are based on IRS National Standards and Local Standards, which cap what the IRS will recognize for food, clothing, personal care, housing, transportation, and health care. If your actual expenses are higher than the IRS standards, the IRS disregards the excess. If they are lower, the IRS uses your actual lower number.
The multiplication factor is:
- Lump sum cash offer (paid within five months of acceptance): Monthly disposable income × 12. The IRS is willing to accept a smaller total because you are paying quickly.
- Periodic payment offer (paid in six to twenty-four months): Monthly disposable income × 24. Because the IRS waits longer, it requires a higher total future income component.
For example: if your monthly disposable income after allowable expenses is $400, a lump sum offer requires a future income component of at least $4,800 (400 × 12). A deferred offer requires at least $9,600 (400 × 24).
Putting It Together: A Sample RCP Calculation
Consider a taxpayer with the following profile: a home with $30,000 in net equity after the 80% quick-sale discount and mortgage, a retirement account with a net value of $15,000 after penalties and taxes, a vehicle with $5,000 in equity, and bank accounts totaling $2,000. The total asset component is $52,000. The taxpayer's monthly disposable income after allowable expenses is $300. For a lump sum offer, the income component is $3,600 (300 × 12). The RCP is $52,000 + $3,600 = $55,600. The minimum offer the IRS would accept is $55,600.
If the taxpayer's total tax debt is $200,000, an offer of $55,600 represents a significant reduction — roughly 72 cents on the dollar in tax relief. This is the promise of the OIC program when the numbers genuinely support it.
Why So Many Offers Get Rejected
The IRS rejects approximately two-thirds of submitted offers. The most common reasons are directly tied to RCP miscalculations:
- The taxpayer undervalued assets, and the IRS's investigation revealed higher equity in real estate or retirement accounts.
- The taxpayer used actual living expenses rather than IRS standards, inflating the expense side and understating monthly disposable income.
- Dissipated assets — money spent before the offer was filed — were not disclosed and were later identified by the IRS.
- The taxpayer's income increased between financial disclosure and IRS review, raising the income component.
- The offer was submitted as a lump sum but was actually funded through a deferred payment arrangement that the IRS reclassified.
A properly prepared OIC requires accurate disclosure, strategic timing, and a thorough understanding of how the IRS will evaluate every line of the financial statement. An offer built on a realistic RCP calculation — not wishful thinking — is the one that stands the best chance of acceptance.
