Offer in Compromise: Doubt as to Liability

Challenge the Amount of Tax You Actually Owe

Doubt as to Liability (DATL) OIC applies when there's genuine dispute about whether you owe the assessed tax amount—or any tax at all. Unlike DATC (based on inability to pay), DATL challenges the legal correctness of the tax assessment itself. This requires demonstrating the IRS made an error in calculating your liability.

"IRS assessed $94K based on unreported 1099 income from identity theft. Taxpayer never received funds. We gathered police reports, affidavits, and bank records proving fraud. DATL offer accepted—entire liability eliminated."

*Illustrative scenario. DATL requires proving legal error in assessment. Results vary based on evidence and circumstances.

Do You Qualify? Quick Self-Assessment

DATL OIC may apply if:

You were a victim of identity theft with fraudulent returns filed

The IRS used incorrect information to calculate your tax

You have proof the income was never received

The IRS applied the wrong tax law to your situation

Deductions or credits were incorrectly disallowed

You can document the error with records

Important: DATL is harder to prove than DATC. You must have evidence showing the IRS assessment is legally incorrect—not just that you can't pay.

Common DATL Scenarios

Identity Theft

Someone filed a fraudulent return using your SSN or reported false 1099 income. You never received the money the IRS thinks you earned.

Most Common DATL Case

Incorrect Substitute for Return

IRS filed an SFR with no deductions or exemptions. Your actual liability with proper deductions is significantly lower.

File Correct Return Instead

Wrong Taxpayer

Liability was assessed against the wrong person due to SSN errors, similar names, or data entry mistakes.

Clerical Error

Expired CSED

The Collection Statute Expiration Date has passed, but IRS is still pursuing collection on legally unenforceable debt.
