Yes, the IRS can come after you for your spouse’s taxes, and it happens more often than people expect. If you filed a joint return, both of you owe the entire bill regardless of who earned the income or caused the problem. If you live in a community property state, you can be on the hook for tax on your spouse’s income even when you file separately. Relief is possible in specific situations, but each option has strict eligibility rules and deadlines that shut the door permanently once missed.
Joint Returns Make Both Spouses Fully Liable
Signing a joint return triggers what the tax code calls joint and several liability. Under 26 U.S.C. § 6013(d)(3), when spouses file jointly, the liability for the tax is joint and several.1Office of the Law Revision Counsel. 26 USC 6013 – Joint Returns of Income Tax by Husband and Wife In practice, the IRS can collect 100% of the tax, penalties, and interest from either spouse. Who earned the money, who prepared the return, who signed first, who spent the refund — none of that limits what the IRS can pursue from you.
This liability survives divorce. A divorce decree that assigns past tax debt to your ex-spouse is a private agreement between the two of you. The IRS is not a party to it and is not bound by it. If your ex fails to pay, the IRS will collect from you for the full amount, and your only remedy is to go back to family court and try to enforce the decree against your ex separately.
Community Property States Reach You Even When You File Separately
Filing a separate return does not fully insulate you if you live in a community property state. Under state law in these jurisdictions, income earned by either spouse during the marriage is generally owned equally by both, and the IRS follows those state rules. Per IRS Publication 555, the community property states are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin.2Internal Revenue Service. Publication 555 (12/2024), Community Property
If you file separately in one of these states, you report half of all community income plus all of your own separate income, and you attach Form 8958 showing how you divided it. So if your spouse earns $120,000 and you earn nothing, you still report $60,000 on your separate return. If your spouse doesn’t pay tax on their half, the IRS may look to your share of community assets to collect. Idaho, Louisiana, Texas, and Wisconsin treat income from separate property as community income; the other five do not, which complicates the analysis further.
Three Types of Innocent Spouse Relief
Congress built three separate escape valves into 26 U.S.C. § 6015. Each targets a different situation, and they don’t overlap much. Picking the wrong one is a common reason claims fail.
Traditional Innocent Spouse Relief
This is the one most people picture, and it’s the hardest to win. Under § 6015(b), you have to show four things: you filed a joint return; that return understated tax because of your spouse’s erroneous items; you didn’t know and had no reason to know about the understatement when you signed; and it would be unfair to hold you liable.3Office of the Law Revision Counsel. 26 USC 6015 – Relief From Joint and Several Liability on Joint Return The “no reason to know” standard is where most requests collapse. If your spouse’s business was clearly earning income that didn’t appear on the return, or if household spending far exceeded the reported income, the IRS will argue you should have noticed.
Separation of Liability Relief
This option splits the debt between you and your spouse based on which items belong to whom. Under § 6015(c), you qualify only if you’re divorced, legally separated, or have lived apart from your spouse for at least 12 months before you file the election. Once approved, you owe only the portion of the understatement tied to your own income and deductions.
Two limits matter. Separation of liability applies only to understatements, meaning the return itself was wrong. If the return was correct but the tax simply went unpaid, this route doesn’t help. And if the IRS can show you actually knew about the erroneous item when you signed, you’re disqualified.
Equitable Relief
Equitable relief under § 6015(f) is the catch-all. If you don’t qualify for the other two, the IRS can still grant relief when holding you liable would be unfair given all the facts. It’s also the only form of relief that covers underpayments, meaning cases where the return was accurate but the tax was never paid.
The IRS weighs a set of factors from Revenue Procedure 2013-34: whether you’re still married to the spouse who caused the debt, whether paying would cause economic hardship (measured against 250% of the federal poverty guidelines), whether you knew or should have known about the problem, whether the divorce decree assigned the debt to your ex, and whether you got a significant benefit from the unpaid taxes beyond ordinary support.4Internal Revenue Service. Revenue Procedure 2013-34 Abuse by the nonrequesting spouse carries substantial weight. If your spouse controlled the finances or used intimidation to prevent you from questioning the return, the IRS will factor that in even where you technically had knowledge.
Injured Spouse Is a Different Claim
Injured spouse relief sounds like innocent spouse relief and solves a completely different problem. Innocent spouse relief (Form 8857) is about not owing the debt. Injured spouse relief (Form 8379) is about protecting your share of a joint refund when the IRS applies it to your spouse’s separate obligations.5Internal Revenue Service. About Form 8379, Injured Spouse Allocation
The debts that can trigger a refund offset include federal tax debts from prior years, past-due child support, federal agency nontax debts such as defaulted federal housing loans, state income tax obligations, and certain unemployment compensation overpayments.6Taxpayer Advocate Service. How to Prevent a Refund Offset To qualify as an injured spouse, you must have filed jointly, had earned income, and made federal tax payments through withholding or estimated payments that contributed to the refund. You can file Form 8379 with the joint return or separately after learning of the offset.
Deadlines That Can End Your Claim
The three innocent spouse options do not share a single deadline, and this catches people out. Traditional innocent spouse relief and separation of liability relief both carry a strict two-year deadline. The clock starts on the date the IRS first begins collection activity against you, typically when you receive a Notice and Demand for Payment or when the IRS offsets your refund against the joint liability.7Internal Revenue Service. Instructions for Form 8857 – Request for Innocent Spouse Relief Miss the window and those two doors close for good.
Equitable relief works differently. Under § 6015(f)(2), you can request equitable relief for unpaid taxes any time before the IRS collection period expires, which is generally ten years from the date of assessment. For overpayments you have already made, you file within the period allowed for a refund claim. That longer window is precisely why equitable relief exists as a backstop when the two-year deadline is gone.
How to File for Relief
All three types of innocent spouse relief use one form: Form 8857, Request for Innocent Spouse Relief. Do not attach it to your annual tax return. Mail it separately to:
Internal Revenue Service Center
Attn: Stop 840F
7940 Kentucky Drive
Florence, KY 410428Internal Revenue Service. Where to File – Forms Beginning With the Number 8
You can also fax the form and all attachments to 855-233-8558. Faxing creates an immediate record of your submission date, which matters if you’re close to the two-year cutoff.
Documentation is what carries these claims. Pull copies of the joint returns at issue, every IRS notice you’ve received, your divorce decree or separation agreement, and financial records showing your involvement or lack of involvement in household finances. If you’re claiming equitable relief based on abuse, include whatever you can produce: protection orders, police reports, medical records, or statements from people who witnessed the situation. For economic hardship, gather documentation of your income, monthly expenses, and assets.
What Happens While Your Request Is Pending
The IRS is required by law to notify your spouse or former spouse about your request and give them a chance to participate. There is no way around this. If you have safety concerns tied to an abusive spouse, note it on Form 8857; the IRS has procedures to limit the information shared, but the basic notification still goes out.
Expect the review to take six months or longer. The IRS may ask for more documentation during that time before issuing a preliminary determination letter. If your request is approved, you’re relieved of the allocated portion of the debt, and you may be entitled to a refund of payments already applied to it.
Meanwhile, collection can continue. Under IRC § 6331, the IRS can levy a joint bank account even when only one spouse owes the tax. It doesn’t split the balance 50/50. It treats both account holders as equal owners and can seize up to the full balance regardless of who deposited the money. Once the levy notice hits the bank, the bank freezes the account and holds the funds for 21 days. If the debt isn’t resolved in that window, the IRS takes the money. A non-liable spouse can request a partial release for funds that are provably theirs, but the burden of proof is on you, and commingled deposits are hard to untangle after the fact. If your spouse owes back taxes, keeping your earnings in a joint account puts them within reach.
If Your Request Is Denied
A denial is not the last word. Within 30 days of the preliminary determination letter, either spouse can file Form 12509, Innocent Spouse Statement of Disagreement, to appeal through the IRS Independent Office of Appeals.9Internal Revenue Service. Appeal an Innocent Spouse Determination Send the form and any new documentation to the IRS address on your determination letter, not directly to the Office of Appeals, or it will slow the process. Lay out your facts in chronological order with specific dates.
If the administrative appeal fails, you can petition the U.S. Tax Court. Under § 6015(e), you have 90 days from the date the IRS mails its final determination letter to file. If the IRS has not made a final determination within six months of your original filing, you can go to Tax Court at that point without waiting further. The Tax Court reviews your eligibility independently rather than deferring to the IRS decision. The 90-day window is firm. Miss it and the Tax Court loses jurisdiction over your claim.
