Innocent spouse relief: getting out of a spouse's tax debt

When you file a joint return, both spouses are "jointly and severally" liable for the full tax — even if one of you earned all the income or made the error, and even after divorce. A divorce decree that assigns the debt to your ex doesn't bind the IRS. Innocent spouse relief is the legal way to separate yourself from liability that isn't fairly yours. See divorce tax debt.

Innocent spouse relief covers understated tax — income left off or deductions improperly claimed by your spouse — when you didn't know and had no reason to know of the understatement, and it would be unfair to hold you liable.

Separation of liability divides an understatement between you and a spouse you're divorced, legally separated or living apart from (for the prior 12 months) or who has died. You're responsible only for your share.

Equitable relief is the catch-all. It can cover underpaid tax — tax correctly reported but not paid — as well as understatements that don't qualify under the first two types, when it would be unfair to hold you liable considering all the facts, including abuse, economic hardship and who benefited.

For innocent spouse relief and separation of liability, you generally must file Form 8857 no later than two years after the IRS first begins collection activity against you (for example, an offset of your refund or a notice of intent to levy). For equitable relief, the deadline is longer: generally within the period the IRS can collect the tax, or for refunds, within the refund statute. Don't wait — file as soon as you're aware of the problem.

The IRS looks at what you knew, your involvement in finances, whether you benefited beyond normal support, current marital status, whether you'd suffer economic hardship, any abuse or financial control, and your compliance with tax laws since. Documentation helps: evidence of separate finances, abuse, or that your spouse concealed information. The IRS will contact your spouse or ex-spouse, who can participate — the law requires it — though it doesn't share your new address or certain sensitive information.

Innocent spouse relief is different from injured spouse allocation (Form 8379). Injured spouse is for when your share of a joint refund is taken to pay your spouse's separate past-due debt — such as their prior tax, child support or student loans — while you're not responsible for that debt. It recovers your share of the refund; it doesn't address joint liability.

1. Confirm the joint-year balance and how it arose using a transcript.
2. Complete Form 8857, answering every question; the IRS uses the form to decide which type of relief fits.
3. Attach documentation supporting your knowledge, hardship or abuse claims.
4. Mail or fax as instructed, and keep proof.
5. Keep filing your own returns and paying current taxes.
6. If denied, you can appeal and, in many cases, petition the U.S. Tax Court within 90 days of the final determination.

You may have a strong case if your spouse handled the finances and hid income or accounts from you, you were subjected to abuse or financial control, you're now divorced or separated, you didn't benefit from the unpaid tax beyond ordinary support, and paying would cause you economic hardship. Your case is weaker if you signed the return knowing about the income or the unpaid balance, you shared in lavish spending funded by the unreported income, or you participated in the business that generated the error. Being unaware of tax law alone isn't enough; the question is whether you knew, or should have known, the facts that created the tax. Each request is decided on its own facts, so even if some factors weigh against you, it's often worth applying — especially when abuse or hardship is involved.
