Innocent spouse relief: who qualifies and how to file Form 8857

What innocent spouse relief covers

When you sign a joint return, both spouses are each responsible for the full tax, even after a divorce. Innocent spouse relief is the IRS process that can release you from tax, interest and penalties that trace back to your spouse or former spouse. A divorce decree that says your ex will pay does not bind the IRS, so this is the federal route.

You make one request on Form 8857, and the IRS weighs it under all three types of relief. You do not have to pick the right type yourself, but knowing which one fits helps you explain your case clearly.

The three types of relief and innocent spouse relief requirements

Innocent spouse relief

This type removes tax added because your spouse left out income or claimed deductions or credits wrongly. The Form 8857 instructions list four innocent spouse relief requirements, and you must meet all of them.

1. You filed a joint return for the year.
2. The return understated the tax because of erroneous items of your spouse or former spouse.
3. When you signed, you did not know and had no reason to know the tax was understated.
4. Considering all the facts, it would be unfair to hold you liable.

Separation of liability relief

Separation of liability relief splits the understated tax between you and your spouse as if you had filed separately, so you pay only the part tied to your own items. You qualify only if you are divorced, legally separated, widowed, or have lived apart for the full 12 months before you file Form 8857. It does not cover items you actually knew about when you signed.

Equitable relief from the IRS

Equitable relief is the fallback when you do not qualify for the other two. It is the only type that can cover an underpayment, meaning tax that was correctly shown on the return but never paid, as well as an understatement. The test is whether, given all the facts, it would be unfair to hold you responsible.

Form 8857 asks detailed questions about your marriage, finances and what you knew, and your answers are the evidence the IRS weighs. Be specific and consistent. Our tax debt relief options page covers other routes if relief is denied.

Can I get relief if I knew about the error?

Usually not under innocent spouse relief. You are shut out if you had actual knowledge of the error, or if a reasonable person in your position would have known. Separation of liability likewise does not reach items you actually knew about.

There is an important exception. If you were a victim of spousal abuse or domestic violence before signing the return, and you did not challenge the items because you feared retaliation, the IRS may grant relief even though you knew. Describe what happened on Form 8857 and include any documents you have, such as protective orders, police reports or statements from a counselor.

Relief is also not available for years where you already signed an offer in compromise or a closing agreement covering the same tax. If you are weighing an offer in compromise, note that the IRS asks you to resolve any open innocent spouse claim before it will look at an offer.

Deadlines to file Form 8857

The deadline depends on the type of relief and on whether you want money back or want a balance removed. Missing the 2-year window does not always end your case, because equitable relief has longer limits.

The Form 8857 instructions count as collection activity a section 6330 notice (the pre-levy notice of your right to a hearing), an offset of your refund against a joint debt from another year, a suit against you, or an IRS claim in a court case. Check the dates on letters addressed to you, not just to your former spouse. Separate rules apply to relief from community property laws: file no later than 6 months before the assessment period ends, or within 30 days of IRS contact about an examination.

The community property states are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin. If you lived in one of them and did not file jointly, you may still ask for relief on Form 8857 from how state law divided income.

Filing Form 8857 step by step

1. Get the current Form 8857 and its instructions from IRS.gov, and list each tax year you want relief for.
2. Answer the questions about your marriage, education, finances, your involvement in household money matters, and what you knew when you signed.
3. Explain in your own words why it would be unfair to hold you liable, and describe any abuse along with whatever records you have.
4. Attach supporting papers: divorce or separation decree, proof of a separate address, and records showing who handled the finances.
5. Mail it to Internal Revenue Service, P.O. Box 120053, Covington, KY 41012, or fax it to the number in the instructions. Do not attach it to your tax return or send it to the Tax Court.
6. Keep a copy and proof of the mailing date.

How long the IRS takes and what happens while you wait

The IRS says a review can take about 6 months, and sometimes longer. It first confirms the form is complete, then sends a questionnaire to the other spouse and gathers records. Answer any letter by its deadline, since missing information is a common cause of delay.

While the request is pending, the 10-year collection clock is suspended, as explained on our IRS collection statute of limitations page. Interest keeps growing on any balance that is not relieved, so paying undisputed amounts can still make sense.

Review, appeal and Tax Court

Once the IRS has the information it needs, it sends a preliminary determination letter to both of you. Either spouse can appeal to the IRS Independent Office of Appeals within 30 days of the date on that letter. After that you receive a final determination letter.

If you disagree with the final determination, you can petition the US Tax Court no later than the 90th day after the IRS mails that letter. You can also petition if you have not received a final determination within 6 months of filing Form 8857. The filing fee is $60 and can be waived; see our Tax Court petition guide.

Free help is available. A Low Income Taxpayer Clinic represents people below certain income levels in disputes with the IRS for free or a small fee, and the Taxpayer Advocate Service can step in if the request stalls and causes hardship.
