IRS Form 8857 Instructions: Filing, Deadlines, and Review

The instructions for IRS Form 8857 walk you through four parts on a paper form: your identifying information, the type of innocent spouse relief you want, your current marital and living situation, and a written explanation of why you should not be held liable for the tax. You gather supporting documents, sign, and mail or fax the package to the IRS in Kentucky. The form cannot be e-filed and must always be submitted separately from your tax return.¹

Before You Start

Pull together the following before opening the form:

Social Security numbers for you and your current or former spouse.
Current and former addresses covering the tax years at issue.
The tax years you want relief for.
Any IRS notices you have received about the debt.
Financial records that show where the tax problem came from: W-2s, 1099s, bank statements, prior returns.
Divorce decree or separation agreement, if applicable.
Documentation of abuse, financial control, or health issues if those are part of your story.

If you do not have every document yet, file anyway. The IRS instructions specifically say not to delay filing while you gather paperwork, because the deadlines are strict.¹

Make Sure Form 8857 Is the Right Form

Form 8857 asks the IRS to release you from a tax debt caused by your spouse’s actions on a joint return. It is not the form for a refund that was seized to pay your spouse’s separate debts like past-due child support or defaulted student loans. That situation calls for Form 8379, Injured Spouse Allocation, which is a different form with different rules and can be e-filed with your return.¹

Completing the Form Part by Part

Part I: Identifying Information

Enter your name, current address, and Social Security number, then the same information for your spouse or former spouse. List each tax year you are requesting relief for. If the debt covers multiple years, list them all rather than filing separate forms.

Part II: Type of Relief

Check the box for the type of relief you want. You can check more than one. If you are not sure which fits, check every box that might apply and let the IRS evaluate your request under each. Filing under the wrong single category is not a reason to lose a valid claim, but leaving a category unchecked can mean the IRS does not consider it.² The three categories are innocent spouse relief (for understatements you did not know about), separation of liability (which divides the debt between you and your spouse and requires that you be divorced, separated, widowed, or living apart for the past 12 months), and equitable relief (the catch-all, and the only category that covers unpaid tax where the return itself was correct).

Part III: Marital and Household Status

Answer the questions about your current marital status and living situation honestly and with dates. Whether you are divorced, legally separated, widowed, or living apart from the other spouse determines whether separation of liability relief is on the table. If you have lived apart from your spouse, be specific about when you moved out or when they moved out, because the 12-month rule turns on those dates.

Part IV: Your Explanation

This is the section that decides most cases. Write a narrative that answers three questions:

What were the erroneous items on the return, or what caused the unpaid balance?
Why did you not know, and have no reason to know, about the problem when you signed?
Why would it be unfair to hold you responsible?

Specifics beat generalities. “My spouse handled all tax preparation and refused to show me the returns before filing” carries more weight than “I didn’t handle the finances.” If abuse, financial control, or health issues shaped your ability to know or challenge what was on the return, describe them with dates and context. If your income is low, say so; economic hardship weighs in your favor when your income falls below 250% of the federal poverty guidelines, and it can still count above that threshold if you have $300 or less per month left after basic living expenses.³

Attach Your Supporting Documents

Attach everything that backs up what you wrote in Part IV. Useful attachments include:

Divorce decree or separation agreement, especially for separation of liability claims.
Police reports, restraining orders, medical records, or court documents for abuse or financial control claims.
Emails, texts, or letters showing your spouse concealed financial information.
Pay stubs, bank statements, or benefit letters supporting a hardship claim.

Write your name and Social Security number on every page of every attachment. The IRS processes large volumes of these requests, and pages that get separated from your file without identifying information can be lost.

Where to Send It

Form 8857 must be paper-filed, separately from your tax return. Send the completed form and all attachments to one of the following addresses:¹

By U.S. Postal Service: Internal Revenue Service, P.O. Box 120053, Covington, KY 41012.
By private delivery service such as FedEx or UPS: Internal Revenue Service, 7940 Kentucky Drive, Stop 840F, Florence, KY 41042.

You can also fax the package to the IRS at the number listed in the form instructions. Keep copies of everything, and if you mail it, use a method that gives you delivery confirmation.

Filing Deadlines

Which deadline applies to you depends on the type of relief you checked in Part II. Missing the deadline is one of the most common ways a valid claim gets denied.

Innocent Spouse Relief and Separation of Liability

You must file within two years after the IRS first attempts to collect the tax from you. Collection activity that starts the clock includes the IRS offsetting your refund or sending a notice demanding payment. This is a statutory deadline and the IRS cannot extend it.⁴

Equitable Relief

Deadlines depend on what you are asking for:¹

To be relieved of an unpaid balance: generally until the end of the 10-year collection period that runs from when the tax was assessed. Certain events can extend that period.
To get a refund of amounts already paid: within three years after the original return was filed, or two years after the tax was paid, whichever is later.
For a mix of both: the refund deadline governs the paid portion, and the collection period governs the unpaid portion.

Community Property Relief

If you filed separately in a community property state (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, or Wisconsin) and are seeking relief from tax on your spouse’s income, file no later than six months before the statute of limitations on assessment expires for your spouse’s tax year. If the IRS opens an examination during that six-month window, you have 30 days from the initial contact letter.¹

What Happens After You File

Your Spouse Gets Notified

The IRS is required by law to contact your spouse or former spouse and give them the opportunity to participate.² You cannot block this notification, and it applies even in situations involving past abuse. The non-requesting spouse can submit their own information and dispute your account. If your safety is a concern, tell the IRS in Part IV; the agency has procedures for handling those situations, but the notification itself still happens.

Collection Generally Pauses

While the IRS reviews your request, it generally cannot levy your wages, seize property, or take other collection action against you for the liability at issue.⁵ Existing levies should be released once your claim is processed. IRS policy is also not to offset your refunds during the review, though that protection comes from internal policy rather than statute.

Review Timeline

The IRS warns that a decision can take six months or longer.² Keep filing your annual returns and paying current-year taxes while you wait; a pending request does not excuse other obligations.

If the IRS Denies Your Request

A denial is not the last word. The IRS first sends a preliminary determination letter to both spouses explaining the reasoning. You have 30 days from the date of that letter to appeal by filing Form 12509, Statement of Disagreement, along with any additional documentation, to the address on your letter.⁶ Present your information in chronological order with specific dates.

After the full review, the IRS issues a final determination. If you still disagree, you have 90 days from the date of that letter to petition the United States Tax Court. The filing fee is $60.⁷ If the IRS has not issued a final determination within six months of your filing, you can petition the Tax Court at that point without waiting.⁶

State Taxes Are Separate

A favorable IRS decision on Form 8857 does not automatically relieve you of state tax liability. Most states with an income tax require a separate state-level request on a state-specific form, and the deadlines may differ from the federal ones. Check with your state’s tax agency. Filing the federal request first is usually the better sequence, because a favorable IRS determination can strengthen the state case.
