Innocent Spouse Relief provides relief from joint federal tax liability when one spouse is unaware of the other spouse's improper tax reporting, or when imposing joint liability would be inequitable. Under IRC Section 6015, the IRS offers three distinct forms of relief, each with its own requirements. Innocent spouse relief is most commonly sought after divorce or separation, when a former spouse's tax problems threaten the other spouse financially.

How joint filing creates joint liability

When spouses file a joint federal tax return, they are jointly and severally liable for the tax, interest, and penalties — meaning either spouse can be held responsible for the entire amount. This is true even after divorce: a divorce decree cannot change federal tax liability. If one spouse concealed income, claimed false deductions, or otherwise caused a tax problem, the IRS can collect the full amount from the other spouse unless that spouse qualifies for innocent spouse relief.

Three types of relief

Section 6015 provides three avenues of relief: Traditional innocent spouse relief (Section 6015(b)) — for understatements of tax on a joint return where the requesting spouse did not know and had no reason to know. Separation of liability (Section 6015(c)) — for divorced, separated, or widowed taxpayers, allocates the tax liability between spouses based on who earned or caused the item. Equitable relief (Section 6015(f)) — a catch-all for cases where the other two do not apply but holding the spouse liable would be inequitable.

Traditional innocent spouse relief requirements

To qualify: (1) filed joint return with understatement of tax; (2) understatement caused by erroneous items of the other spouse (unreported income, false deductions); (3) at the time of signing, the requesting spouse did not know and had no reason to know; (4) considering all facts, it would be unfair to hold the requesting spouse liable. The "knowledge" standard is often the hardest to meet — courts consider education level, involvement in family finances, and whether the tax understatement was substantial relative to household income.

Separation of liability

Available to spouses who are: legally separated, divorced, widowed, or have lived apart for 12 months. The IRS allocates each item of tax understatement to whichever spouse caused it. You are only responsible for items allocated to you. This is often easier to establish than traditional innocent spouse relief because the knowledge requirement is different (you just cannot have actual knowledge of items at the time of signing).

Equitable relief

For cases where Traditional and Separation of Liability do not fit but holding the spouse liable would be inequitable. Common examples: underpayment (not understatement) cases where tax was properly reported but not paid; abusive marriage situations; financial hardship cases. The IRS evaluates equitable relief under Revenue Procedure 2013-34 using a multi-factor test.

How to request relief

Innocent Spouse Relief is requested through a formal application (Form 8857). It can be filed at any time the IRS is actively collecting, but timing rules vary by relief type: Traditional and Separation of Liability relief require filing within 2 years of the first IRS collection action; Equitable relief has broader timing rules. The IRS is required to contact the spouse or former spouse as part of the investigation — they have the right to participate.

Frequently asked questions

Can I get innocent spouse relief while still married?+

Yes for Traditional and Equitable relief. Separation of Liability specifically requires legal separation, divorce, widowhood, or 12+ months living apart.

Do I have to notify my spouse of the application?+

No, you do not notify them — but the IRS is required by law to notify them and give them the opportunity to participate in the proceeding. This can be uncomfortable in contentious divorces. The IRS will not share your contact information in abuse cases if you notify them.

How long does the process take?+

Processing typically takes several months. Complex cases can take longer, particularly if the other spouse participates and contests.

What if I signed the return under duress or coercion?+

This may qualify for equitable relief and can also affect whether you should even be considered to have filed a joint return at all. Consult a tax attorney — duress cases have specific legal standards that go beyond standard innocent spouse analysis.

Can I get relief if I benefited from the understated tax?+

Benefit is one factor in the analysis but not automatically disqualifying. If you received no meaningful benefit beyond normal household support, relief may still be available. Lavish personal spending attributable to the tax understatement generally disqualifies you.
