Short answer: If you filed a joint federal return, the IRS treats you and your spouse as both responsible for the tax and any interest or penalty on it, even if you later divorce, even if a divorce decree says your spouse will pay, and even if your spouse earned all of the income (IRS: innocent spouse relief). The IRS offers three kinds of relief, all requested on one form, Form 8857: innocent spouse relief, separation of liability relief and equitable relief. You don’t have to work out which one fits; the IRS reviews your information and applies the type of relief, if any, you’re eligible for (IRS: innocent spouse relief). Two of the three have a 2-year deadline, so the first job is finding the date of the IRS letter.

This page explains how the rules work. It doesn’t promise any IRS result; the IRS decides each request on its own facts.

Why a joint return makes both of you responsible

When you sign a joint return, you both take on the whole tax bill for that year, not half each. The IRS says this holds even if you later divorce, a divorce decree states that your spouse is responsible for the taxes, or your spouse earned all of the income (IRS: innocent spouse relief). A divorce decree can settle things between the two of you, but it doesn’t change what the IRS can collect.

If you get a notice that you owe tax on a joint return, the IRS says to follow the instructions in the letter promptly, and to request spouse relief as soon as you learn of the taxes due (IRS: innocent spouse relief). If the notice is a plain balance-due bill, also read what to do first after an IRS balance-due notice.

The three kinds of spouse relief at a glance

All three are requested on the same form, and the IRS applies separation of liability and equitable relief automatically if you’re eligible, without a separate request (IRS: innocent spouse relief).

Our reading: of the three IRS pages, only the equitable relief page talks about tax that was underpaid, not just understated. So if the return was correct but the balance was never paid, equitable relief is the one to read closely. For how the 10-year collection period works, see the IRS collection clock on our multi-year back taxes guide.

Innocent spouse relief can’t be claimed for taxes due on your own income, household employment taxes, Individual Shared Responsibility payments, business taxes, or trust fund recovery penalties for employment taxes (IRS: innocent spouse relief). Equitable relief has the same exclusions for household employment, shared responsibility, business and trust fund taxes, and is generally granted only for taxes due on your spouse’s income and assets (IRS: equitable relief).

Equitable relief lists a few exceptions where it can reach tax on your own income and assets: you’re responsible for the item only because of community property laws, your spouse used money set aside for taxes for their own benefit without your knowledge, you were the victim of spouse abuse before signing the return, you didn’t question the items on the return because of fear of retaliation, or your spouse’s fraud led to the unpaid or understated tax (IRS: equitable relief). For tax on community income, the IRS sets a separate deadline on that same page; read it there if you live in a community property state.

What “you knew or should have known” means

You can’t get innocent spouse relief for understated taxes if you had actual knowledge of the errors, or if a reasonable person in similar circumstances would have known about them. The IRS says you had actual knowledge if you knew your spouse received unreported income, knew of facts that made a deduction or credit unallowable, or knew your spouse deducted false or inflated expenses (IRS: innocent spouse relief).

Separation of liability adds more bars: you deliberately avoided learning about a taxable item on your return, the taxes are due on property you own jointly with your spouse, or you and your spouse transferred assets to avoid taxes or commit fraud. You may be eligible for partial relief if you didn’t know about part of an item (IRS: separation of liability relief).

For equitable relief, the IRS weighs all the facts. Its examples include your marital status, economic hardship you might suffer without relief, whether you knew or had reason to know, whether you’re legally obligated to pay, whether you significantly benefited, whether you complied in good faith with tax laws afterward, and your mental and physical health. To judge whether you had reason to know, it looks at your education level, your spouse’s deceit or evasiveness, your involvement in the activity and in household and business finances, your financial expertise, and changes in your spending habits (IRS: equitable relief).

If there was abuse

The IRS says you may be eligible for innocent spouse relief or separation of liability relief even if you knew about the errors, if you were the victim of spousal abuse or domestic violence before signing the return, you didn’t challenge the items on the return because of fear, or you signed the joint return because you were pressured or threatened (IRS: innocent spouse relief; IRS: separation of liability relief). The IRS instructions for Form 8857 explain what to include about it. If you’re not safe, put your safety ahead of any tax deadline.

Years where relief isn’t available

For all three kinds, the IRS says you’re not eligible in any year when you signed an offer in compromise with the IRS, you signed a closing agreement covering the same taxes, a court made a final decision denying you relief, or you took part in a related court proceeding and didn’t ask for relief (IRS: innocent spouse relief). That’s one reason to sort out a possible spouse-relief claim before you sign an offer; see how an offer in compromise application works.

How to ask for relief, and what happens next

1. File Form 8857, Request for Innocent Spouse Relief. It covers all three kinds of relief (IRS: innocent spouse relief). The form, its instructions and the related publication are on the IRS About Form 8857 page.
2. The IRS contacts your spouse or former spouse. It asks whether they want to take part in the process (IRS: innocent spouse relief).
3. Expect a wait. The IRS says review may take up to 6 months or longer. While you wait, keep filing and paying your taxes as usual.
4. You get a determination letter. Generally both spouses have the right to appeal, and you must appeal within 30 days from the date on the determination letter (IRS: innocent spouse relief).

Spouse relief deals with who owes the tax. Penalties on a year you remain responsible for may still be worth a separate look; see IRS penalty abatement: which relief fits and how to ask for it.

Injured spouse is a different thing

The names are close, but the problems are not. Injured spouse relief helps you get back your share of a joint federal refund that was taken to pay your spouse’s overdue debts, such as past-due child support, debts to federal agencies, state income tax, or state unemployment compensation debts, when you weren’t responsible for the debt. You ask with Form 8379, Injured Spouse Allocation, within 3 years from the date the return was filed or 2 years from the date the tax was paid, whichever is later. The IRS says Form 8379 can take up to 8 weeks to process by itself, and longer if you file it with your return (IRS: injured spouse relief). If your refund went to a state debt, see where federal and state tax touch.

In short: innocent spouse (Form 8857) asks the IRS not to hold you responsible for tax on a joint return; injured spouse (Form 8379) asks for your share of a joint refund back.

What to gather before you file

Our suggestion, not an IRS checklist: for each joint year in question, collect

• the IRS letter and the date printed on it (the 2-year windows run from when you received a notice);
• a copy of that year’s joint return, and an account transcript for the year (see how to get an IRS transcript);
• your divorce decree, separation agreement, or other papers showing when you separated or stopped living together;
• anything that shows who handled the money and the filing that year, such as who prepared the return and whose accounts the income went into.

It opens in any spreadsheet app and has one row per tax year: whether it was a joint return, the IRS letter and its date, whether the problem is understated or unpaid tax, whose income or item caused it, your marital status now, whether you lived apart for the 12 months before asking, which relief to ask about, the deadline worked out from the letter, and notes. It’s our own organizing tool, not an IRS form.

Questions to bring to a tax professional

• For each year, is the problem understated tax, unpaid tax, or both?
• Which of my years are still inside the 2-year window from the IRS notice?
• Did I sign anything for these years, such as an offer in compromise or closing agreement, that would make me ineligible?
• Is the tax on my spouse’s income, on my own income, or on business or household employment taxes that spouse relief doesn’t cover?
• Do I need to request relief now even though a payment plan or other collection step is already in place?
• Was my refund taken for my spouse’s debt, so that Form 8379 is the right form instead of, or as well as, Form 8857?

How this page is made

Every IRS rule, deadline and form on this page comes from the IRS page linked beside it: the IRS pages on innocent spouse relief, separation of liability relief, equitable relief and injured spouse relief, and the About Form 8857 page. We read them on October 20, 2026 and checked them again that evening; the text had not changed. The comparison table restates those IRS pages; the “our reading” note, the gather list, the prep sheet and the questions are our own organizing suggestions. Rules and deadlines can change, so if an IRS page differs from this one, follow the IRS page.
