Doubt as to Collectability (OIC Basis) — Definition Glossary

Defined by Sarah Mitchell, CPA | Reviewed by: James Okafor, EA

Full Definition

Doubt as to Collectability is the most common basis for an Offer in Compromise — accepted when the taxpayer demonstrates that the total realizable value of their assets plus future income capacity is less than the total tax debt owed. The IRS uses the Reasonable Collection Potential (RCP) formula: RCP = Net Realizable Value of Assets + Future Income Potential. If the OIC offer amount equals or exceeds the RCP, the IRS is generally required to accept it. Calculating RCP correctly requires detailed financial analysis — the IRS uses strict formulas to value assets (often at forced-sale value, typically 80% of fair market value for real property) and income (net monthly income multiplied by 12 or 24 months, depending on the payment option).

Why This Matters for Businesses With Tax Debt

Understanding Doubt as to Collectability (OIC Basis) is essential for any business owner navigating IRS enforcement. This term directly affects the options available for resolving business tax debt — including whether tax debt financing is available, how lien subordination works, and what enforcement the IRS can take.
