Divorce and Tax Debt
Rates and standards last checked against IRS.gov: November 6, 2026
A divorce ends the marriage, but not your share of joint IRS debt. Here's who the IRS can collect from, and how to limit what you owe to your own share.
Quick answer
Who owes the IRS for joint tax returns after a divorce?
Both of you. When you file jointly, each spouse is responsible for the full tax, interest and penalties, even after divorce and even if the decree assigns the debt to your ex. Separation of liability relief can limit you to your share of understated tax.
Who this applies to: Anyone who filed joint returns with a spouse they are now divorced or separated from.
What can change this answer
- A divorce decree doesn't bind the IRS.
- Request relief on Form 8857.
- File within 2 years after the IRS first tries to collect from you.
Recommended next step
Pull your IRS account transcripts for every joint year before the divorce is final, so you know what's owed.

Why you're both still liable
When you sign a joint return, you and your spouse are each responsible for all of the tax, interest and penalties on it. The IRS says that stays true if you later divorce, if your divorce decree makes your spouse responsible for the taxes, and even if your spouse earned all the income. The IRS can collect the full balance from either of you.

Relief for divorced and separated spouses
One form, Form 8857, covers three kinds of relief, and the IRS applies whichever you qualify for:
- Innocent spouse relief: your spouse understated tax on the joint return and you didn't know
- Separation of liability: you're divorced, separated or living apart, and pay only your share of understated tax
- Equitable relief: it would be unfair to hold you responsible when the other types don't apply
Request relief within 2 years after the IRS first tries to collect from you. The IRS contacts your former spouse, can take 6 months or longer to decide, and sends a determination letter. Either spouse can appeal within 30 days. Our innocent spouse relief guide covers eligibility and the form in detail.
If the debt is your share too
Relief only covers tax your spouse caused. If the balance is partly yours, the usual options apply to your share: an installment agreement, currently not collectible status if you can't pay, or penalty abatement. Your IRS account transcripts show the balance for each joint year.
Tax questions to settle before your divorce is final
Once the decree is signed, the IRS can still collect a joint debt from either of you. Sort these out first.
- Pull IRS account transcripts for every joint year so you know what's owed.
- Find out whether any joint return is under audit or has an open balance.
- Decide who claims the children and who gets any refund for the current year.
- Put any agreement about who pays the IRS in writing, knowing it doesn't bind the IRS.
- If your spouse caused errors you didn't know about, look into Form 8857 before the 2-year deadline.
Frequently asked questions
Am I responsible for my ex's tax debt after divorce?
For years you filed jointly, yes. Both spouses are responsible for the tax, interest and penalties on a joint return, even after divorce.
My divorce decree says my ex pays the IRS. Does that protect me?
Not from the IRS. The IRS says you're both still liable even if a divorce decree says your spouse is responsible. The decree may give you a claim against your ex in state court.
What is separation of liability relief?
If a joint return understated the tax and you're divorced, separated or no longer living with your spouse, you may be able to pay only your share of the understated tax.
Which form do I file?
Form 8857. It covers innocent spouse relief, separation of liability and equitable relief, and the IRS applies whichever type you qualify for.
Will the IRS contact my ex?
Yes. The IRS contacts your spouse or former spouse to ask whether they want to take part in the review.
What if I knew about the errors?
Generally you can't get innocent spouse relief, but there's an exception if you were a victim of spousal abuse or domestic violence and didn't challenge the return out of fear.
