A Doubt as to Liability (DOL) Offer is a type of Offer in Compromise that allows taxpayers to settle tax debt for less than the full amount owed when there is a legitimate dispute about whether the correct amount of tax is actually due. This offer type addresses situations where the taxpayer disagrees with the IRS’s assessment of liability and has evidence supporting their position that the tax liability is incorrect or should be different from what the IRS claims.
Doubt as to liability exists when there is a genuine dispute about the existence or amount of the tax debt based on law or fact. Common situations include disputes over whether income was correctly reported, disagreements about the application of tax law to specific situations, questions about whether penalties were properly assessed, situations where the IRS assessed tax without the taxpayer filing a return (substitute for return assessments), and cases where the taxpayer has evidence contradicting the IRS’s determination of liability.
DOL offers differ fundamentally from the more common doubt as to collectibility offers. With DOL offers, the issue isn’t ability to pay—it’s whether the tax is actually owed. Financial information is generally not required for DOL offers since the dispute centers on the correctness of the liability itself, not on ability to pay. The offered amount should reflect what you believe you actually owe based on correct application of tax law.
To apply for a DOL offer, submit Form 656 (Offer in Compromise), select “Doubt as to Liability” as the offer type, provide detailed explanation of why you dispute the liability, attach supporting documentation including tax returns, financial records, correspondence, legal authorities, or other evidence supporting your position, and pay the required application fee. No initial payment is required for DOL offers (unlike collectibility offers).
The IRS examines the evidence to determine if reasonable doubt exists about the assessed liability. If accepted, you pay the agreed amount and the remaining debt is forgiven. DOL offers are relatively rare because most liability disputes are resolved through standard audit reconsideration, appeals, or tax court procedures before reaching the Offer in Compromise stage. These offers work best when audit reconsideration isn’t available due to timing or procedural reasons.
