Quick overview
When a married couple files a joint federal tax return, the law generally makes both spouses jointly and severally liable for the entire tax shown on the return and any additional tax that results from IRS adjustments. The IRS recognizes that this rule can be unfair in cases of fraud, misreporting, or hidden income. To address that, the IRS provides three distinct relief paths: innocent spouse relief, separation of liability (also called separate liability relief), and equitable relief. (See IRS Topic No. 156 and Publication 971 for the official rules.) IRS Topic No. 156 | IRS Publication 971 (Innocent Spouse Relief)
This article explains when each form of relief applies, what evidence helps, the application process (Form 8857), timing considerations, and practical tips based on practitioner experience.
How does relief from joint tax liability work?
- Innocent spouse relief: Designed for spouses who signed a joint return but can show they did not know (and had no reason to know) that the pair’s tax was understated or liabilities were misstated. If approved, the requesting spouse is relieved of the additional tax, interest, and penalties attributable to the erroneous items.
- Separation of liability relief: Applies when spouses are no longer married, legally separated, or have not lived together for a year. It allocates the understated tax and related penalties between the spouses so the requesting spouse is responsible only for their portion.
- Equitable relief: For cases that don’t meet the tests for innocent or separation of liability relief but where it would be unfair to hold the requesting spouse liable considering all the facts and circumstances.
Each form of relief is requested using IRS Form 8857, Request for Innocent Spouse Relief. The IRS will generally ask for supporting documentation and may issue Letter 3179 requesting further proof. (See FinHelp’s guide to How to Apply for Innocent Spouse Relief and the FinHelp page on Form 8857).
Who is eligible for each type of relief?
Innocent spouse relief — typical criteria
- You filed a joint return on which your spouse (or former spouse) reported erroneous items (understated income, false deductions, etc.).
- You can show you did not know and had no reason to know about the error when you signed the return.
- It would be inequitable to hold you responsible for the tax (for example, you didn’t benefit from the income).
- You generally must file Form 8857 to start the process. (IRS Pub. 971 describes these rules in detail.)
Separation of liability relief — typical criteria
- You are no longer married, are legally separated, or have not lived with your spouse for the 12 months prior to filing the claim.
- You can show which items (income or deductions) are attributable to the other spouse; the IRS will allocate the understated tax accordingly.
Equitable relief — typical criteria
- You do not qualify for innocent or separation relief, but, considering all facts and circumstances (economic hardship, abuse, lack of knowledge, and whether you benefited), it would be unfair to hold you liable.
- The IRS uses a multi-factor test, including whether you were abused or coerced, whether you significantly benefited from the understatement, and whether you had reason to know of the error.
Note: Injured spouse relief is different — it addresses refund offsets when one spouse’s past-due debt (e.g., child support, student loans) causes the IRS Treasury Offset Program to take an otherwise joint refund. That claim is made on Form 8379, not Form 8857. See FinHelp’s comparison of Form 8379 vs. Innocent Spouse Relief and the article on Injured Spouse Relief.
Typical evidence the IRS looks for
- Copies of the joint tax return and any amended returns.
- Bank statements, pay stubs, W-2s, 1099s to show your knowledge (or lack of it) of income.
- Canceled checks, receipts, or invoices for deductions and expenses.
- Divorce agreements, separation orders, or other court records if relying on separation of liability.
- Documents showing your financial situation and whether you benefitted from the item(s) in question (household spending, transfers, assets acquired with the income).
In practice, the IRS assigns an examiner to evaluate the Form 8857 claim and often issues Letter 3179 requesting additional documentation. Preparing a clear, chronological set of exhibits saves time and improves the odds of a favorable determination. (See FinHelp’s evidence checklist: Filing an Innocent Spouse Claim: Process and Documentation).
Procedural steps: how to apply and what to expect
- Gather documents. Organize tax returns, bank records, W-2s/1099s, bills, divorce papers, and a personal statement describing what you knew and when.
- Complete and submit Form 8857. Give clear, concise answers and attach documents. There is no filing fee.
- The IRS will review and may request additional records (Letter 3179). Respond promptly and comprehensively.
- The IRS may grant relief, deny relief, or grant partial relief (for separation of liability). If denied, you have appeal rights and can request Collection Due Process or file a petition to U.S. Tax Court in some circumstances.
Practical timeline: The IRS review process can take several months. If the claim is complex, expect 6–12 months before a final decision. If the IRS is actively collecting (levies, wage garnishments), filing Form 8857 can pause levies in certain situations, but there are limits. If collection is imminent or happening, consult a tax professional immediately to stop an enforced collection while the claim is pending. (IRS Topic No. 156.)
Time limits and the two‑year collection rule
There is a critical timing rule tied to collection: if you want the IRS to stop collection actions against you while your claim is evaluated, you generally must file Form 8857 within two years after the IRS first attempted to collect the tax from you. Missing that collection-related two‑year window does not automatically eliminate your chance for relief, but the IRS is less likely to grant equitable collection relief and you may remain subject to collection while the claim is processed. See IRS Publication 971 for the official guidance. (IRS Pub. 971.)
Common mistakes and how to avoid them
- Waiting too long: Don’t delay. File Form 8857 as soon as you know there’s an issue — document dates and collection notices.
- Poor documentation: Vague statements without corroborating records reduce credibility.
- Confusing injured spouse relief with innocent spouse relief: Use Form 8379 when your refund is offset for the other spouse’s debts; use Form 8857 to be relieved of tax liability itself.
- Assuming relief is automatic: The IRS applies tests and looks at the totality of circumstances; approval is not guaranteed.
Real-world examples
-
Example 1 (Innocent spouse): A taxpayer signed a joint return but had no involvement in the spouse’s business. The spouse failed to report substantial cash receipts. The innocent spouse showed bank records, testimony that they did not handle business finances, and no benefit from the undisclosed income. The IRS granted innocent spouse relief.
-
Example 2 (Separation of liability): After a divorce, one spouse conceded that specific rental and business items were theirs. The requesting spouse successfully allocated responsibility for their share and was relieved of the other spouse’s tax liabilities on those items.
-
Example 3 (Equitable relief): A taxpayer who did not qualify for innocent spouse relief because they technically should have known of the error still received equitable relief where evidence showed abuse, coercion, and no ability to challenge how return items were reported.
When to get professional help
In my 15+ years helping clients, I’ve seen timely, well-documented claims obtain relief far more often than claims filed hastily or without supporting records. If the tax amount is material, an audit or legal history exists, or collection actions have begun, consult a tax attorney, enrolled agent, or CPA experienced in innocent spouse claims. They can:
- Help assemble a coherent evidence file.
- Draft the narrative statement that accompanies Form 8857.
- Communicate with the IRS examiner and respond to Letter 3179.
- Advise on appeals or alternative remedies like Offers in Compromise if relief is denied.

Frequently asked questions
- How do I start? File Form 8857 and attach copies of the joint return(s), a clear personal statement, and supporting documents.
- Will filing Form 8857 stop collection? It can pause certain collection steps if you qualify under the two‑year collection rule, but don’t assume it will stop all enforcement—get professional help if levies or garnishments are active.
- Can I get interest and penalties removed? If you receive relief, the IRS may abate the tax, interest, and penalties attributable to the erroneous items, but interest sometimes continues to accrue until abatement is processed.
