When married couples file a joint federal tax return, both spouses become “jointly and severally liable” for the tax owed. That legal phrase means the IRS can collect the full amount, plus interest and penalties, from either spouse, even if only one of them earned the income or made the mistake. It does not matter that a divorce decree assigns the debt to your ex. The IRS is not bound by a divorce agreement.
For people who signed a joint return without knowing their spouse underreported income or claimed improper deductions, this rule can be devastating. Innocent spouse relief is the set of IRS provisions that can remove some or all of that liability. This guide explains the three types of relief, how the IRS decides who qualifies, the deadlines, and how to apply.
Understanding Joint and Several Liability
Filing jointly often lowers a couple’s total tax, which is why most married couples choose it. The tradeoff is shared responsibility. If the IRS later audits the return and finds unreported income, overstated deductions, or credits that should not have been claimed, it can assess the resulting tax against both spouses. If the balance is not paid, collection action such as levies or refund offsets can target either person.
Innocent spouse provisions exist because Congress recognized that this rule can be unfair when one spouse had no knowledge of, or control over, the problem. Relief is not automatic; you have to ask for it, and the IRS evaluates each request based on the facts.
The Three Types of Relief
The IRS offers three distinct forms of relief from joint liability. You request all of them with the same form, and the IRS will consider each type you may qualify for.
1. Innocent Spouse Relief
This is the narrowest type. It applies to an understatement of tax, meaning tax that should have been shown on the return but was not, caused by an erroneous item of your spouse or former spouse. Examples include unreported income your spouse earned or a deduction your spouse claimed improperly. To qualify, generally:
- You filed a joint return that has an understatement of tax due to your spouse’s erroneous items.
- You establish that when you signed the return you did not know, and had no reason to know, about the understatement.
- Taking into account all the facts and circumstances, it would be unfair to hold you liable.
The IRS looks at factors such as your education, your involvement in household finances, whether your spouse hid information, and whether you received a significant benefit, beyond normal support, from the unpaid tax. Partial relief may be granted if you knew about part of the understatement but not its full extent.
2. Separation of Liability Relief
This type allocates the understatement between you and your spouse as if you had filed separate returns. You are responsible only for the portion attributable to you. To be eligible, at the time you file the request you must be:
- Divorced or legally separated from the spouse you filed jointly with, or
- Widowed, or
- Not a member of the same household as that spouse at any time during the 12-month period ending on the date you file the request.
Separation of liability relief is not available if the IRS proves you had actual knowledge of the item that caused the understatement, and it can be denied in cases of fraudulent transfers of assets between spouses. Like innocent spouse relief, it applies only to understatements, not to tax that was correctly reported but never paid.
3. Equitable Relief
Equitable relief is the broadest and most flexible type. It is the only option that can cover an underpayment, meaning tax that was properly shown on the return but not paid. For example, if your spouse told you the balance due would be paid and it never was, equitable relief may help. It can also apply to understatements when you do not qualify for the other two types.
The IRS weighs many factors, including your marital status, whether you would suffer economic hardship if relief were denied, whether you knew or had reason to know the tax would not be paid, whether you or your spouse had a legal obligation to pay under a divorce agreement, whether you received a significant benefit, your compliance with tax laws since then, and whether you were subject to abuse. No single factor decides the outcome.
The Role of Abuse
The IRS gives special consideration to spouses who experienced domestic abuse or financial control. If abuse or fear of retaliation prevented you from questioning the return or challenging your spouse, that can weigh in your favor even if you knew about the item. Documentation such as protective orders, police reports, or statements from counselors or doctors can support your request, but the IRS also considers your own detailed statement.
Deadlines to Request Relief
Timing matters, and the deadlines differ by type:
- Innocent spouse relief and separation of liability relief: Generally, you must request relief no later than two years after the date the IRS first began collection activity against you. Collection activity includes things like a levy notice or an offset of your refund against the joint debt. A bill or a notice of audit by itself does not usually start the clock.
- Equitable relief: You must request relief within the period the IRS has to collect the tax, which is generally 10 years from the assessment date, or, if you are seeking a refund, within the period for claiming a refund.
Because collection can start years after the return was filed, read every IRS notice carefully and act as soon as you learn about a joint liability you believe is unfair.
How to Apply: Form 8857
All three types of relief are requested with Form 8857, Request for Innocent Spouse Relief. Key steps include:
- Gather the tax years involved. You can request relief for multiple years on one form.
- Complete the form thoroughly. It asks about your marriage, education, involvement in finances, knowledge of the items, any abuse, and your current financial situation.
- Attach supporting documents. Divorce decrees, separation agreements, evidence of separate households, bank records, and documentation of abuse can all help.
- Write a clear explanation. Describe in your own words why you did not know about the problem, or why it would be unfair to hold you liable.
- Mail or fax it according to the current instructions. Do not attach Form 8857 to your tax return.
The law requires the IRS to notify your spouse or former spouse and give them a chance to participate. They may provide information supporting or opposing your request. The IRS does not share your current address or contact information with them, and if you are concerned for your safety, you should note that on the form.
While a request is pending, the IRS generally cannot levy to collect the tax from you for the years involved, though interest continues to accrue and the collection period is suspended.
If the IRS Denies Your Request
The IRS will send a preliminary determination letter. If you disagree, you can appeal to the IRS Independent Office of Appeals. After a final determination, or if the IRS does not issue one within six months of your request, you can generally petition the U.S. Tax Court. Tax Court deadlines are strict, typically 90 days from the date of the final determination letter, so do not wait.

Innocent Spouse vs. Injured Spouse
These terms sound alike but address different problems:
- Innocent spouse relief addresses liability for tax on a joint return caused by your spouse’s errors or nonpayment.
- Injured spouse allocation, requested on Form 8379, applies when your share of a joint refund is taken to pay your spouse’s separate past-due debts, such as child support, student loans, or prior tax debts. It lets you recover your portion of the refund.
If you are dealing with a seized refund for your spouse’s old debt, injured spouse is likely the right path. If you are being billed for a joint return problem, innocent spouse relief is the one to explore.
Tips to Strengthen Your Request
- Be specific and honest. Vague statements carry less weight than concrete details about who handled the finances and what you were told.
- Show limited control. Evidence that your spouse controlled the accounts, kept records hidden, or made decisions alone supports a lack-of-knowledge claim.
- Demonstrate no significant benefit. Show that you did not enjoy unusual luxuries funded by the unpaid tax.
- Stay compliant now. Filing and paying your current taxes on time is a factor the IRS considers.
- Consider professional help. A tax attorney, CPA, or enrolled agent can help organize evidence and present your case, especially if large balances or complicated finances are involved.

Frequently Asked Questions
Q: Does a divorce decree protect me from my ex-spouse’s tax debt?
No. A divorce decree is binding between you and your former spouse, but it does not bind the IRS. If you filed jointly, the IRS can still collect from you. A decree assigning the debt to your ex may help as a factor for equitable relief and may give you a claim against your ex in state court.
Q: Can I get relief from tax that was reported but not paid?
Innocent spouse relief and separation of liability relief only apply to understatements. For a balance that was correctly reported but not paid, equitable relief is the type to request.
Q: Will my former spouse find out that I filed Form 8857?
Yes. The IRS is required to notify the other spouse and allow them to participate, but it will not disclose your current address or other personal contact details.
Q: How long does the IRS take to decide?
Processing times vary and can take many months. You can check the IRS website for current information, and you may contact the IRS or the Taxpayer Advocate Service if your case is delayed and causing hardship.
Q: Can I request relief if I am still married to my spouse?
Yes. Innocent spouse relief and equitable relief do not require divorce or separation. Separation of liability relief does require that you be divorced, legally separated, widowed, or living apart for the required 12 months.
Q: Do I need a lawyer to file Form 8857?
No, you can file on your own. Many people do. However, professional help can be valuable if the amounts are large, abuse is involved, or the IRS has already denied a request.
The Bottom Line
Filing jointly creates shared liability, but the law recognizes that one spouse should not always pay for the other’s mistakes. If you are facing a tax bill from a joint return you did not understand or control, review the three types of relief, note the deadlines, and file Form 8857 with as much supporting detail as possible. Acting quickly preserves your options.
