Reasonable Collection Potential — RCP — is the number the IRS uses to evaluate every Offer in Compromise. It answers one question: what is the minimum amount the government can realistically expect to collect from you, given your income, expenses, and assets?
If your offer equals or exceeds your RCP, the IRS will generally accept it. If your offer falls below your RCP, the IRS will reject it. Understanding how RCP is calculated is not optional if you are seriously considering an OIC — it is the entire analysis.
How RCP Is Calculated
RCP has two components that are added together:
RCP = Future Income Value + Net Realizable Asset Equity
Both components require analysis. Neither is intuitive.
Component 1: Future Income Value
The IRS calculates your monthly disposable income — what you earn minus your allowable monthly expenses — and multiplies it by a set number of months depending on your offer payment type.
- Cash offer (paid within 5 months of acceptance): disposable income × 12
- Periodic payment offer (paid in installments over 6–24 months): disposable income × 24
This multiplier reflects the IRS’s estimate of what it could collect from your income stream over the remaining collection period, discounted for the certainty of receiving it now.
The allowable expenses framework is critical. Your disposable income is not your actual take-home pay minus your actual expenses. It is your income minus what the IRS will allow as expenses — and those two numbers are often very different.
The IRS uses four categories of allowable expenses:
National Standards — Fixed monthly amounts for food, clothing, personal care, and out-of-pocket health care costs. These are the same nationwide and are not negotiable. If you spend more than the standard, the IRS uses the standard. If you spend less, the IRS still uses the standard.
Local Standards — Housing and utilities, and transportation. These vary by county and metropolitan area. The IRS publishes updated local standards annually.
Actual expenses — Certain expenses are allowable at actual cost if they are necessary and reasonable: taxes, minimum payments on secured debt, health insurance premiums, court-ordered payments, childcare necessary for employment, and others.
Conditional expenses — Expenses the IRS may allow if you can demonstrate they are necessary for your health, welfare, or production of income. These require documentation and are often disputed.
The gap between what you actually spend and what the IRS will allow is frequently the most contested part of an OIC. Knowing which expenses are allowable — and how to document the ones that are — significantly affects where your RCP lands.
Component 2: Net Realizable Asset Equity
The IRS also counts the equity you hold in assets. This is added to your future income value to produce your total RCP.
Asset equity is not calculated at fair market value. The IRS uses quick sale value — typically 80% of fair market value — to account for the discount a forced or rapid sale would produce. From that quick sale value, the IRS subtracts any secured debt to arrive at net realizable equity.
Assets the IRS evaluates:
- Real estate — Primary residence and any other real property. Equity = (FMV × 80%) minus outstanding mortgage balance.
- Bank and financial accounts — Checking, savings, money market. Full balance counted.
- Vehicles — The IRS applies a local standard for vehicle value. Equity above that standard is counted.
- Retirement accounts — Included, but typically discounted for early withdrawal taxes and penalties.
- Business assets — Accounts receivable, equipment, inventory. Evaluated at quick sale value.
- Other investments — Stocks, bonds, cryptocurrency, life insurance cash value.
Having significant asset equity does not automatically eliminate OIC eligibility. It raises the bar for what an acceptable offer looks like.
Dissipated Assets
The IRS looks backward as well as forward. If you disposed of assets in the period leading up to your OIC — sold property, transferred assets, made large withdrawals — the IRS may add the value of those dissipated assets to your RCP even though you no longer hold them.
The IRS’s position is that assets you controlled and chose to dispose of could have been used to pay the tax debt. This does not make every prior asset transfer a problem, but it is a factor that needs to be evaluated before an OIC is filed.
What RCP Tells You About OIC Viability
Once you understand your RCP, the OIC math becomes clear.
If your RCP is $8,000 and you owe $95,000 in back taxes, you are a strong OIC candidate. An offer near $8,000 settles a $95,000 liability. That is the scenario OIC was designed for.
If your RCP is $87,000 and you owe $95,000, an OIC is unlikely to make sense. The IRS will not accept an offer meaningfully below what they calculate they can collect. In that scenario, an installment agreement or another resolution path is probably more appropriate.
If your RCP is negative — your allowable expenses exceed your income and your assets have no meaningful equity — Currently Not Collectible status may be the appropriate path. Learn more about CNC status →
The OIC acceptance rate published by the IRS — approximately 21% in fiscal year 2024 — includes offers filed by people who were never viable candidates. For taxpayers whose RCP genuinely supports an offer, the odds look considerably better.
Why Getting RCP Right Matters — and Why Most People Get It Wrong
The financial analysis behind an RCP calculation looks straightforward on paper. Income minus expenses plus asset equity. Taxpayers and even some practitioners treat it as a simple form-filling exercise.
It is not. And the consequences of getting it wrong fall entirely on the taxpayer.
The two most common failure modes:
Offer rejected at full liability. This happens when the RCP calculation is done incorrectly — allowable expenses are understated, assets are overvalued, the quick sale discount is not applied, or dissipated assets are missed entirely. It also happens when the IRS overstates your income in their own analysis — using gross figures instead of net, counting one-time deposits as recurring income, or pulling from a prior year that does not reflect your current situation. The IRS runs its own analysis on every offer it receives. If their RCP is materially higher than yours, they reject the offer and demand full payment. The taxpayer has now spent time, money, and months of the collection statute on a submission that never had a chance. Knowing how the IRS will calculate income — and where they commonly get it wrong — is part of building a defensible offer.
Offer accepted at more than was necessary. This is the failure mode nobody talks about — because the offer was technically accepted. But if the allowable expense calculation was done sloppily, if the correct national and local standards were not applied, if conditional expenses that should have been included were left off — the taxpayer paid more than the IRS was entitled to collect under the OIC formula. The IRS does not volunteer that your offer is higher than your RCP. They accept it.
The gap between what a taxpayer thinks their expenses are and what the IRS will actually allow — and conversely, what the IRS will allow that the taxpayer did not realize was includable — is where most OIC submissions go wrong. National standards, local standards, and the rules around actual versus conditional expenses are specific, updated annually, and applied mechanically. Getting the numbers right requires knowing the rules, applying them correctly to the specific financial picture, and documenting everything.
The IRS calculates its own RCP for every offer it receives. The goal of proper analysis is to arrive at the lowest defensible offer amount — a number grounded in the actual allowable expense standards and a complete, accurate picture of assets. Not an arbitrary figure. Not a guess. A calculation the IRS cannot legitimately reject because the math is correct and the documentation is clean.
The financial disclosure that supports an OIC is a sworn statement. It has to be accurate, it has to be defensible, and it has to be built by someone who knows how the IRS will read it.
What We Do
Before we recommend an OIC to any client, we complete a full RCP analysis: pull transcripts, verify the liability, identify all assets and equity positions, build the financial disclosure, and calculate the lowest offer amount the numbers can support.
If the RCP analysis shows the OIC is not viable, we say so and recommend the path that actually fits the situation. We do not take cases we do not believe we can resolve.
