IRC § 6015 — Form 8857

Innocent Spouse Relief

When you filed a joint tax return and your spouse hid income or claimed fraudulent deductions, the IRS can still pursue you for 100% of the liability. Innocent Spouse Relief is the legal mechanism to separate yourself from a tax debt that was not your fault.

Joint and Several Liability: Why This Program Exists

When you sign a joint tax return, you are jointly and severally liable for the entire tax — including any taxes owed because your spouse lied on the return. The IRS can collect the full balance from either spouse, regardless of who earned the income or claimed the deductions. IRC § 6015 was enacted specifically to give relief to spouses who were unaware of — and did not benefit from — the errors that caused the liability.

The Three Types of Relief Under IRC § 6015

You must qualify for at least one of three distinct relief types. They have different eligibility standards, and applying for one does not prevent you from applying for another. The IRS considers all types you request when you file Form 8857.

1

Classic Innocent Spouse Relief

IRC § 6015(b) — Available to all filing statuses

The foundational relief type. You are relieved of liability for a tax understatement caused by your spouse's erroneous items — as long as you meet all five statutory requirements.

You Must Show All of These

  • Joint return was filed for the tax year
  • There is an understatement due to erroneous items of your spouse
  • You did not know, and had no reason to know, of the understatement when you signed
  • Taking all facts into account, it would be unfair to hold you liable

Disqualifying Factors

  • You knew about the erroneous items (or should have known)
  • You significantly benefited from the understatement (beyond normal living)
  • You committed fraud or transferred assets to evade tax
The "knew or should have known" standard:The IRS looks at whether a reasonable person in your situation would have questioned the item. Receiving unexplained large deposits, signing returns showing implausible income or deductions, or having education and financial sophistication may increase the "should have known" bar.
2

Separation of Liability Relief

IRC § 6015(c) — Requires divorce, legal separation, or 12+ months apart

Instead of eliminating liability entirely, this relief type apportions the deficiency between you and your spouse based on who actually caused the erroneous items. You are only liable for the portion attributable to you.

Eligibility Requirements

  • Divorced or legally separated from the spouse
  • Or: not living together for at least 12 months before filing Form 8857
  • Filed Form 8857 within 2 years of first IRS collection contact

How Apportionment Works

The IRS allocates the deficiency to the spouse whose items caused it. If your spouse hid $50,000 of business income, that deficiency is allocated to them. You pay only what is attributable to items on your side of the return.

Important: This relief is not available if the IRS can show that you actually knew about the erroneous items when you signed the return. Knowledge is an absolute bar — not just a factor to weigh.
3

Equitable Relief

IRC § 6015(f) — Catch-all relief when Types 1 and 2 do not apply

Equitable Relief applies when you do not qualify for Classic or Separation relief, but it would be fundamentally unfair to hold you liable. This is the broadest type — it can apply even when the tax was correctly reported (but not paid), not just understatements.

Unique to Equitable Relief

  • Available for underpayments (correctly reported but not paid)
  • No 2-year deadline — must file before CSED expires
  • Divorce not required

IRS Considers These Factors

  • Current marital status
  • Economic hardship if held liable
  • Knowledge or reason to know of the liability
  • Legal obligation of your spouse to pay (divorce decree)
  • Significant benefit received from the unpaid tax
  • Abuse or financial control by the other spouse

Deadlines: When You Must File Form 8857

The 2-Year Deadline Is Strictly Enforced

For Classic Innocent Spouse (§ 6015(b)) and Separation of Liability (§ 6015(c)) relief, you must file Form 8857 within 2 years of the date the IRS first attempted to collect from you. This is not 2 years from when you filed the return or when the IRS audited you — it is 2 years from the first IRS collection contact (levy notice, lien filing, offset of refund, etc.).

Deadline Summary by Relief Type

Classic Innocent Spouse (§ 6015(b))

2 years from first IRS collection contact

Strictly enforced. Missing this deadline forfeits the right to this relief type.

Separation of Liability (§ 6015(c))

2 years from first IRS collection contact

Same strict 2-year rule. Divorce or legal separation must already exist.

Equitable Relief (§ 6015(f))

Before the CSED expires (up to 10 years)

IRS Revenue Procedure 2013-34 eliminated the 2-year rule for Equitable Relief.

Form 8857 Walkthrough

Form 8857 (Request for Innocent Spouse Relief) is the official application. It is a narrative form as much as a data form — the IRS needs your story, not just numbers.

Part I

Which Tax Years You Are Requesting Relief For

List every tax year for which you are requesting relief. You can request multiple years on one form. Be comprehensive — you cannot add years after submission without filing a new form.

Part II

Your Current Marital Status

Indicate whether you are still married to the same spouse, divorced, legally separated, or widowed. This determines which relief types you are eligible for (particularly Separation of Liability).

Part III

The Erroneous Items and What You Knew

Describe each item that caused the understatement. For each item, explain whether you knew about it, why you did or did not know, and what you did or would have done differently if you had known. Be detailed and honest — vague answers invite denial.

Part IV

Your Financial Situation

The IRS evaluates whether holding you liable causes economic hardship. Provide income, expenses, and assets. If paying the liability would leave you unable to meet basic living expenses, state this clearly with documentation.

Part V

Domestic Abuse or Financial Control

If your spouse used physical or emotional abuse or financial control to prevent you from questioning tax filings, describe this. It is a significant factor in Equitable Relief and can affect confidentiality of IRS notice to your spouse.

Attachments

Supporting Documentation

Include: divorce decree (if applicable), financial records, any correspondence from your spouse admitting to the understatement, evidence of abuse if applicable, and any prior IRS collection notices.

The Spouse Notification Requirement

When the IRS receives your Form 8857, they are generally required to send a notice to your spouse or former spouse informing them of your claim. That person has 30 days to respond and present their side. The IRS considers their response before making a decision.

What Your Spouse Can Do

  • Contest your claim and provide counter-information
  • Provide evidence you knew about the erroneous items
  • Show you significantly benefited from the understatement

Domestic Violence Exception

If notifying your spouse would put you at risk of harm, indicate this on Form 8857. The IRS has procedures to withhold your address and certain information from the notice. You can also call the IRS directly (1-800-829-1040) to discuss confidential handling before you file.

Community Property State Rules

If you live in a community property state, the rules are more complex. Community property law generally treats all income earned during the marriage as owned 50/50 by both spouses — which affects how the IRS calculates each spouse's share of the liability.

The 9 Community Property States

ArizonaCaliforniaIdahoLouisianaNevadaNew MexicoTexasWashingtonWisconsin

In community property states, if you file separate returns, each spouse must report 50% of community income — even if only one spouse earned it. If one spouse hid community income and the other spouse did not report their 50% share on a separate return, the other spouse may owe tax on income they never knew about.

The IRS can grant relief from this liability under IRS Revenue Procedure 2013-34 (Equitable Relief) if you meet the conditions. Publication 555 explains the community property rules in detail.

If Your Claim Is Denied: Appeals and Tax Court

A denial of your Form 8857 is not the final word. You have two levels of review available.

1

IRS Appeals Office

Within 30 days of the denial notice, request an Appeals conference. An Appeals Officer reviews your case independently from the examiner who denied it. You can present new evidence and arguments. Appeals resolves the majority of innocent spouse cases without litigation.

2

United States Tax Court

Within 90 days of the Appeals denial (or IRS final decision), you can petition Tax Court for a standalone innocent spouse case under IRC § 6015(e). You do not need a deficiency notice to petition — an innocent spouse denial is enough. The Tax Court reviews the case fresh (de novo), not just whether the IRS was arbitrary. IRS collection is suspended during Tax Court proceedings.

Innocent Spouse Cases Benefit Significantly from Professional Guidance

Form 8857 is a narrative application where the quality of your explanation — what you knew, when you knew it, why it would be unfair — determines the outcome. A tax attorney or enrolled agent experienced in innocent spouse cases can build the strongest factual record for your claim.

Frequently Asked Questions

What is Innocent Spouse Relief?
Innocent Spouse Relief is a provision under IRC § 6015 that allows one spouse to be relieved of joint tax liability when the other spouse (or former spouse) understated income or claimed improper deductions on a joint return. When you file a joint return, both spouses are jointly and severally liable for the entire tax — meaning the IRS can collect the full amount from either one. Innocent Spouse Relief is the mechanism to escape liability you did not know about and did not benefit from.
What are the three types of Innocent Spouse Relief?
Under IRC § 6015, there are three types: (1) Classic Innocent Spouse Relief (§ 6015(b)) — for understatements caused by erroneous items of the other spouse that you did not know about; (2) Separation of Liability Relief (§ 6015(c)) — available after divorce or legal separation, apportions the deficiency between spouses based on who caused it; (3) Equitable Relief (§ 6015(f)) — a catch-all for situations where you don't qualify for the first two but it would be unfair to hold you liable.
Is there a deadline to file for Innocent Spouse Relief?
Yes. For Classic Innocent Spouse Relief and Separation of Liability Relief, you must file Form 8857 within 2 years of the date the IRS first attempted to collect the tax from you. For Equitable Relief, the IRS waived the 2-year deadline — you must file before the Collection Statute Expiration Date (CSED) expires. The deadline runs from the first IRS collection contact, not from when you filed the return.
Can I request Innocent Spouse Relief if I am still married?
Yes, but your options are more limited. Separation of Liability Relief (§ 6015(c)) requires you to be divorced, legally separated, or not living together for at least 12 months. Classic Innocent Spouse Relief (§ 6015(b)) and Equitable Relief (§ 6015(f)) are available regardless of current marital status — you do not have to be divorced to qualify.
What happens if my Innocent Spouse claim is denied?
If the IRS denies your Form 8857, you can appeal to IRS Appeals within 30 days of the denial notice. If Appeals also denies it, you have 90 days to petition the United States Tax Court for a standalone innocent spouse case — even if you have no other tax dispute pending. The Tax Court reviews the case de novo (fresh review, not deferring to the IRS).
What is the IRS Innocent Spouse Notice — and what must I watch for?
When you file Form 8857, the IRS is generally required to notify your spouse or former spouse of your claim (unless there is evidence of domestic abuse). That person has 30 days to respond and provide their side of the story. The IRS considers their input before deciding. If you have concerns about your spouse being notified — particularly domestic violence situations — note this on Form 8857; the IRS has procedures for confidential handling.
