Innocent Spouse Relief: Getting Off a Joint Tax Debt
The three forms of relief from a spouse's or former spouse's tax, who qualifies for each, the deadlines, and how the IRS decides.

When you file a joint return, both spouses are liable for the entire tax, even after divorce. Innocent spouse relief can remove your liability for tax attributable to your spouse's income or errors. There are three routes — traditional innocent spouse relief, separation of liability, and equitable relief — each with its own tests, requested on Form 8857.

What are the three types?
| Type | Covers | Key requirements |
|---|---|---|
| Innocent spouse (Section 6015(b)) | Understatement of tax from the other spouse's erroneous items | You did not know and had no reason to know; unfair to hold you liable |
| Separation of liability (Section 6015(c)) | Understatement allocated to the other spouse | Divorced, legally separated, widowed, or not in the same household at any time in the 12 months before filing; no actual knowledge of the item |
| Equitable relief (Section 6015(f)) | Understatements and unpaid tax shown on the return | Relief under the first two unavailable; unfair to hold you liable under all the facts |
Only equitable relief covers tax that was reported correctly but never paid.
How does the IRS decide equitable relief?
The IRS weighs marital status, economic hardship, knowledge or reason to know, legal obligations under a divorce decree, significant benefit from the unpaid or understated tax, compliance with tax laws since, and your mental or physical health. Abuse or financial control by the other spouse can outweigh knowledge. No single factor decides.
What are the deadlines?
Innocent spouse and separation of liability requests must be filed within two years after the IRS first began collection activity against you — such as a notice of intent to levy with collection due process rights, an offset of your refund to another year's joint tax, or a collection suit or court claim. Equitable relief for unpaid tax can be requested any time within the collection period, generally 10 years from assessment; for refunds, within the refund period — three years from filing or two years from payment, whichever is later.
What happens after you file?
The IRS must notify the other spouse, who may participate and object. The IRS cannot collect from you for that year while the request is pending, though interest and penalties keep accruing. You can appeal a denial within the IRS within 30 days of the determination letter, and you can petition the Tax Court no later than 90 days after the IRS mails its final determination letter, or once six months pass without one.
How is this different from an injured spouse claim?
An injured spouse claim (Form 8379) recovers your share of a joint refund that was offset for the other spouse's separate debts — past-due child or spousal support, federal nontax debts such as student loans, state income tax or unemployment compensation debts, or their own past-due federal tax. It does not involve any error on the joint return.
Frequently asked questions
Can I get relief if I signed the return without reading it?
Signing without reading does not by itself prove lack of knowledge; the IRS asks whether a reasonable person in your position would have known. Education, involvement in finances, and lifestyle relative to reported income all matter.
Does divorce automatically split the tax?
No. A divorce decree assigning the tax to one spouse binds the spouses, not the IRS.
Can I request relief for several years at once?
Yes, on one Form 8857, listing each year.
What if my spouse and I still live together?
Traditional innocent spouse and equitable relief remain available; separation of liability requires being divorced, legally separated, or widowed, or not sharing a household at any time in the 12 months before you file.
