Key takeaways

• When you sign a joint return, you become jointly and severally liable for the entire tax on it. That includes tax on your spouse's income and the results of your spouse's mistakes or dishonesty.

• The tax code offers three kinds of relief: traditional innocent spouse relief, separation of liability, and equitable relief (IRC §6015(b), (c) and (f)). You request all three on Form 8857.

• Equitable relief covers tax that was correctly reported but never paid. You can request it any time the IRS can still collect, which is generally up to 10 years after assessment.

• Your divorce decree doesn't bind the IRS. Even if the decree makes your ex responsible for the taxes, the IRS can still collect from you unless you get relief.

• If the case goes to the Tax Court, the court mostly looks at the record you build with the IRS. Present your full story and evidence from the start.

Why you may owe tax on income you never saw

Married couples who file jointly each become liable for the full tax, interest and penalties on that return (IRC §6013(d)(3)). The IRS can collect the whole amount from either spouse, whoever is easier to collect from. That's often the spouse who has a W-2 job, a house in their name, or a refund coming.

Common situations where relief comes up:

• a spouse underreported business or self-employment income, or invented deductions;

• an audit of a joint return years later, after the marriage has ended;

• a spouse who said they would pay the balance due and never did;

• income from investments, crypto or a side business the other spouse didn't know about;

• financial control or abuse that kept one spouse from questioning the return.

The three types of relief at a glance

• Covers — Innocent spouse relief §6015(b): Understated tax (a deficiency) from your spouse's erroneous items; Separation of liability §6015(c): Understated tax (a deficiency); Equitable relief §6015(f): Understated tax and unpaid tax shown on the return

• Marital status — Innocent spouse relief §6015(b): Any; Separation of liability §6015(c): Divorced, legally separated, widowed, or not living together for the 12 months before you file; Equitable relief §6015(f): Any

• Knowledge test — Innocent spouse relief §6015(b): You didn't know and had no reason to know of the understatement; Separation of liability §6015(c): Relief is denied only if the IRS proves you had actual knowledge of the item; Equitable relief §6015(f): Weighed with other factors; abuse can outweigh knowledge

• Deadline — Innocent spouse relief §6015(b): 2 years after the IRS's first collection activity against you; Separation of liability §6015(c): 2 years after the first collection activity; Equitable relief §6015(f): While the collection period is open (or the refund period, for refunds)

• Refunds available? — Innocent spouse relief §6015(b): Yes; Separation of liability §6015(c): No; Equitable relief §6015(f): Yes

You don't have to choose. One Form 8857 asks the IRS to consider every type you may qualify for.

1. Traditional innocent spouse relief (§6015(b))

You may qualify if all of these are true:

• you filed a joint return;

• the return understated the tax because of erroneous items of your spouse: unreported income, or improper deductions, credits or basis;

• when you signed, you didn't know and had no reason to know of the understatement;

• considering all the facts, it would be unfair to hold you liable.

If you knew about part of the problem, you can still get relief for the part you didn't know about.

"Reason to know" is the hard part. The IRS asks whether a reasonable person in your position would have known: your education, your role in the household's finances, whether there were lavish expenditures, and whether your spouse was evasive or deceptive.

2. Separation of liability (§6015(c))

If you are divorced, legally separated, widowed, or have lived apart for the full 12 months before filing your request, you can ask the IRS to split the understated tax as if you had filed separately. Each of you is responsible only for the items allocable to you.

This is often the strongest option for former spouses. Here the IRS carries the burden of proving you had actual knowledge of the item. "Reason to know" isn't enough. Separation of liability doesn't produce refunds of amounts already paid, and it doesn't cover tax that was reported but unpaid.

3. Equitable relief (§6015(f))

Equitable relief is the catch-all. It's the only kind of relief for an underpayment: the return showed the correct tax, but it wasn't paid. It also covers understatements when you don't qualify under (b) or (c).

The IRS evaluates equitable relief under Rev. Proc. 2013-34:

• Threshold conditions: you filed a joint return; the request is timely; the liability is attributable to your spouse's item (with exceptions, including for abuse); there were no fraudulent transfers between you; you didn't file the return with fraudulent intent.

• Streamlined approval: relief is usually granted if you are no longer married, you would suffer economic hardship without relief, and you didn't know or have reason to know about the problem. For an underpayment, that means you reasonably believed your spouse would pay.

• Otherwise, a factor test: marital status; economic hardship; knowledge or reason to know; which spouse had a legal obligation to pay (for example, under a divorce decree); whether you significantly benefited from the unpaid tax; whether you've stayed compliant with tax laws since; and your mental and physical health.

Abuse matters. If your spouse abused you or exercised financial control, and that kept you from questioning the return or paying the tax, the IRS can grant relief even where you otherwise would have had "reason to know."

Deadlines

• Innocent spouse relief and separation of liability: within 2 years after the IRS's first collection activity against you. That means a levy notice with hearing rights, an offset of your refund against the joint debt, or a lawsuit or court claim. Ordinary bills such as CP14 don't start the clock.

• Equitable relief: any time while the IRS can still collect the tax (generally 10 years from assessment). For a refund, any time within the refund period (see our refund statute of limitations guide). Congress lengthened this deadline in the Taxpayer First Act of 2019, which is why old articles citing a two-year limit for equitable relief are out of date.

How to apply: Form 8857 and what happens next

1. File Form 8857, Request for Innocent Spouse Relief. Include a detailed written statement and supporting documents: bank records, emails, the divorce decree, medical or police records if there was abuse, and evidence of who controlled the finances.

2. The IRS must notify your spouse or ex-spouse, who can give the IRS information. The IRS won't share your new address, phone or employer. Tell the IRS if you have safety concerns.

3. Collection pauses on the years at issue. While the claim and any Tax Court case are pending, the IRS generally can't levy for those years (IRC §6015(e)(1)(B)). The collection statute is suspended during that period. The IRS can still file liens and apply your refunds to the balance.

4. Preliminary determination, then the right to appeal to the IRS Independent Office of Appeals.

5. Final determination. If you disagree, petition the U.S. Tax Court within 90 days. You can also petition if the IRS hasn't decided within six months of your request (IRC §6015(e)(1)(A)).

Build the record early. Since 2019, the Tax Court reviews innocent spouse cases on the administrative record, plus only newly discovered or previously unavailable evidence (IRC §6015(e)(7)). A thin Form 8857 that "saves the details for later" can lose a case you should have won.

Innocent spouse vs. injured spouse

They sound alike but solve different problems:

• Innocent spouse relief (Form 8857) removes your liability for tax on a joint return.

• Injured spouse allocation (Form 8379) protects your share of a joint refund from being taken for your spouse's separate debts, such as past-due child support, student loans or their own back taxes. You owe nothing yourself; you just want your part of the refund.

What relief doesn't cover

• Business payroll taxes and the Trust Fund Recovery Penalty. These aren't joint-return liabilities; see our TFRP guide.

• Separate returns, where each spouse is already liable only for their own.

• State income tax, automatically. A federal grant doesn't change your state account. New York has its own request process (Form IT-285). New Jersey reviews requests separately through the Division of Taxation. File the state request alongside the federal one.

How we help

Innocent spouse cases are won on facts and documents. As attorneys and CPAs, we:

• rebuild who earned what and who controlled the money, using bank records and returns;

• identify which of the three types of relief fits each year, and preserve every one of them;

• write the Form 8857 statement so the administrative record is complete if the case goes to Tax Court;

• coordinate relief with collection: we pause levies, raise innocent spouse relief in a Collection Due Process hearing, and resolve any balance that remains.

Frequently asked questions

I signed the return. Doesn't that mean I can't get relief? No. Every relief type assumes you signed a joint return. The questions are what you knew, what you had reason to know, and whether holding you liable would be fair.

My ex was supposed to pay the balance due and didn't. Can I get relief? Possibly, through equitable relief. It's the only type that covers tax correctly reported but unpaid. The key question is whether you reasonably believed the tax would be paid.

I'm still married. Can I apply? Yes, for traditional innocent spouse relief and equitable relief. Separation of liability requires divorce, legal separation, widowhood, or living apart for the 12 months before you file.

Will my ex-spouse find out? Yes. The law requires the IRS to notify the other spouse and give them a chance to participate. The IRS won't disclose your contact information.

Can I get my money back? Under traditional innocent spouse relief and equitable relief, you may get refunds of amounts you paid, if your request falls within the refund period. Separation of liability doesn't produce refunds.

How long does the IRS take? Commonly six months or more, and longer when the other spouse contests the request or the case goes to Appeals.
