If you filed a joint return and your spouse or ex-spouse understated the tax, you can ask the IRS to release you from that debt. The request is Form 8857, and there are three different kinds of relief on the one form — innocent spouse relief, separation of liability, and equitable relief.
Which one you qualify for depends on whether you are still married, whether you knew about the problem, and whether the tax was understated or simply unpaid. Getting that distinction right is most of the work.
Why joint returns create this problem
A joint return carries joint and several liability. Each spouse is fully liable for the entire tax, not half of it. Divorce does not change that, and neither does a divorce decree assigning the debt to one spouse. A decree binds the two of you to each other; it does not bind the IRS.
So the IRS can collect the whole balance from whichever spouse is easier to reach — the one with a job, a bank account, or a refund coming.
The three types of relief
| Innocent spouse relief | Separation of liability | Equitable relief | |
|---|---|---|---|
| Covers | Understated tax from your spouse’s erroneous items | Allocates the understatement between you | Understated or unpaid tax |
| Marital status | Any | Divorced, legally separated, widowed, or living apart 12 months | Any |
| Knowledge test | You did not know and had no reason to know | You did not have actual knowledge of the item | Knowledge is one factor among many |
| Deadline | Generally 2 years from first collection activity | Generally 2 years from first collection activity | Broader; tied to the collection or refund period |
The critical practical difference: only equitable relief covers tax that was correctly reported but never paid. That is a very common situation — a couple files an accurate return, one spouse was supposed to pay, and never did. Innocent spouse relief does not reach it. Equitable relief does.
What the IRS looks at
For all three types, the recurring questions are:
- Did you know or have reason to know? The IRS considers your education, your involvement in the family finances, whether you reviewed the return, and whether there were unexplained lavish expenses.
- Would it be unfair to hold you liable? Did you benefit from the unpaid tax beyond normal support?
- Are you divorced or separated now?
- Did you suffer abuse or financial control? This is explicitly weighed, and the IRS has made clear that abuse and financial control can outweigh knowledge. If this applies to you, say so in the application. Signing a return under duress is a separate argument that can invalidate the joint election entirely.
- Was there economic hardship? Whether paying would leave you unable to meet basic living expenses.
- Did you comply with tax laws afterward? Filing and paying on time in later years helps.
How to file Form 8857
- Download Form 8857, "Request for Innocent Spouse Relief," from irs.gov.
- File one form covering all applicable years. You do not file a separate form per year.
- Do not specify which type of relief. The form is designed so the IRS evaluates all three. Asking for the wrong one is not fatal.
- Answer the narrative questions fully. The free-text sections about your involvement in finances, your education, and your household situation are where these cases are won. A form with one-line answers gets denied.
- Attach documentation. Divorce decree, protective orders, medical records, bank statements showing you had no access to accounts, correspondence.
- Watch the two-year clock. For innocent spouse relief and separation of liability, the request is generally due within two years after the IRS first began collection activity against you — a levy, an offset notice, or a Collection Due Process notice. Equitable relief has a more generous window.
- Expect the IRS to contact your spouse. This is required by law. The other spouse gets notice and a right to participate. The IRS will not disclose your address, employer, or phone number. If safety is a concern, say so in the filing.
- Expect it to take months. Six months is common; longer is normal.
What happens while it is pending
Collection against you is generally suspended while the request is under consideration, and the statute of limitations on collection is extended by the same period. If the IRS denies the request, you have 90 days from the notice of determination to petition the U.S. Tax Court, which reviews these cases independently.
If your refund was already taken to pay the joint debt, look at whether injured spouse relief applies instead — that is a different thing entirely, and it is the one people confuse most often.
Innocent spouse vs. injured spouse
| Innocent spouse (Form 8857) | Injured spouse (Form 8379) | |
|---|---|---|
| The problem | You are liable for a tax debt your spouse caused | Your share of a joint refund was seized for your spouse’s separate debt |
| The debt | Joint tax liability | Spouse’s student loan, child support, state tax, or other separate debt |
| What you get | Release from the liability | Your portion of the refund back |
| Timing | After the liability arises | Filed with or after the return |
If your refund vanished to pay a debt that was never yours, Form 8379 is the fix, and the mechanism behind the seizure is explained in the Treasury Offset Program.
If relief is denied, you still have options
Denial of innocent spouse relief does not mean you must pay in full immediately:
- An IRS payment plan spreads the balance over time.
- Currently not collectible status pauses collection when paying would create hardship.
- An offer in compromise settles for less than the full amount when you genuinely cannot pay it.
FAQ
Does my divorce decree assigning the debt to my ex protect me?
Not from the IRS. It gives you a claim against your ex in state court, nothing more. You still need Form 8857.
Can I get relief if I signed the return without reading it?
Possibly, but "I signed whatever was put in front of me" is a weak stand-alone argument. It becomes much stronger combined with evidence of financial control, abuse, or genuine exclusion from the household finances.
What if the tax was reported correctly but just never paid?
Only equitable relief covers that. File Form 8857 anyway; the IRS will evaluate it under the equitable standard.
Will I get a refund of amounts I already paid?
Under innocent spouse relief and equitable relief, refunds of amounts you paid are possible within refund limitation periods. Under separation of liability, refunds are generally not available.
Does filing separately from now on help?
It prevents new joint liability. It does not undo existing joint years.
Is there a fee?
No. Form 8857 is free to file.
