What Is Form 8857?

Form 8857 is the IRS form used to request innocent spouse relief. A taxpayer files it when they believe a spouse or former spouse should be responsible for all or part of a joint-return tax liability, including related penalties and interest.

The form does not simply change a filing status after the fact. It starts an IRS review of whether the requesting spouse qualifies for relief under the innocent spouse rules, separation of liability rules, or equitable relief rules.

Key Takeaways

  • Form 8857 requests innocent spouse relief from the IRS.
  • It relates to joint tax returns and certain liabilities connected to a spouse's or former spouse's error.
  • The IRS must contact the other spouse or former spouse during the process.
  • Form 8857 is not the form for injured spouse refund-offset claims.
  • The form requires facts, explanations, and supporting documentation.

How Form 8857 Works

The taxpayer provides information about the tax years involved, the joint returns, the relationship, the error or liability, finances, knowledge of the issue, and other facts the IRS uses to evaluate the request. The IRS then reviews the case and determines whether relief applies.

Form 8857 can be emotionally and financially sensitive because the IRS generally contacts the other spouse or former spouse. That contact requirement should be understood before filing, especially when there has been conflict, separation, divorce, coercion, or abuse.

The form also asks for a narrative, not just numbers. The IRS needs to understand who handled the return, what each spouse knew, how the liability arose, and why holding the requesting spouse responsible may or may not be appropriate under the relief rules.

What Form 8857 Is Used For

Situation

Form 8857 Role

Unreported income on a joint return

Requests review of whether one spouse should be relieved from liability.

Improper deduction or credit

Explains why the requesting spouse should not be held responsible.

Separated or divorced spouses

Provides facts for possible separation of liability or equitable relief.

Refund offset issue

Usually not the right form; Form 8379 may apply instead.

Form 8857 Versus Form 8379

Form 8857 and Form 8379 are often confused because both involve spouses and taxes. Form 8857 deals with responsibility for joint-return tax liabilities. Form 8379 deals with allocating a joint refund when one spouse's separate debt caused or may cause an offset.

Using the wrong form can delay the process. The key question is whether the problem is tax liability from a joint return or a refund being taken for one spouse's separate debt.

The Bottom Line

Form 8857 is the formal request for innocent spouse relief. It is used when a joint tax liability may be unfairly assigned to one spouse, not when a joint refund has been offset for the other spouse's separate debt.
