Quick overview
Innocent spouse and equitable relief are tax-law tools that can free—or at least reduce—the joint liability one spouse faces because of the other spouse’s tax errors, unreported income, or fraud. These remedies are governed by Internal Revenue Code §6015 and implemented by the IRS. The formal request uses IRS Form 8857, and the IRS evaluates applications case-by-case (IRS Pub. 971; Form 8857 instructions).
This article explains eligibility, how the IRS reviews claims, what evidence matters, realistic timelines, and next steps if the IRS denies relief. I counsel clients on these issues regularly; in practice, successful claims rest on careful documentation and prompt action.

Who can apply and which types of relief exist?
There are three primary ways a requesting spouse can seek relief under §6015:
- Innocent spouse relief (sometimes called “true” innocent spouse) — generally under §6015(b): Seeks relief from liability for specific erroneous items on a joint return when the requesting spouse did not know and had no reason to know of the understatement.
- Separation of liability relief — under §6015(c): Divides tax liability between spouses for years where the spouses are divorced, legally separated, or no longer living together.
- Equitable relief — under §6015(f): Applies when the taxpayer doesn’t meet the rules for (b) or (c), but it would be unfair to hold them liable under all facts and circumstances.
Each path has different legal standards and evidence requirements; the IRS considers the full factual picture in equitable relief cases (IRS Pub. 971).
What eligibility criteria does the IRS use?
For innocent spouse relief (high‑level):
- The tax liability must be from a joint return.
- The understatement must be attributable to the other spouse (the one who caused the error).
- The requesting spouse must show they did not know and had no reason to know about the understated tax when they signed the return.
- Taking into account all facts and circumstances, it must be inequitable to hold the requesting spouse liable.
Key evidence the IRS looks for includes signatures, who prepared the return, access to financial records, how household finances were managed, and whether the requesting spouse benefited from the understatement.
For equitable relief, the IRS considers additional factors, such as:
- Marital status at the time of request (divorce/separation may favor relief);
- Economic hardship (ability to pay);
- Whether the requesting spouse received a significant financial benefit from the understatement;
- Whether there was abuse, deception, or coercion; and
- Whether the requesting spouse had legal obligations to pay the tax.
These factors are spelled out in Publication 971 and the Form 8857 instructions (IRS Pub. 971).
How to apply: the practical steps
- File Form 8857 (Request for Innocent Spouse Relief). That is the required form; do not rely on informal letters alone. The form and instructions tell the IRS what to review and what attachments to include (Form 8857, IRS.gov).
- Assemble documentation. Typical evidence includes bank statements, canceled checks, wage and tax statements (W‑2s, 1099s), divorce or separation agreements, police or court records (if abuse is claimed), and correspondence with the other spouse or tax preparer.
- Explain your knowledge and actions. On Form 8857 and in attachments, clearly state when you first learned of the understatement, what steps you took to investigate, and any steps you took to protect yourself financially.
- Mail the form to the address shown in the instructions or follow the e‑filing guidance if applicable. Keep copies of everything.
- Expect an IRS screening and follow‑up. The IRS may request more documents (Letter 3179 is commonly used to request supporting documentation). If the IRS screens you out, you’ll receive an explanation and possible avenues to appeal.

Evidence that helps (and what usually hurts claims)
Helpful evidence:
- Records showing limited access to household finances (separate accounts, no signing authority);
- No participation in the transactions that generated the understatement (e.g., the other spouse’s business bank records, emails, or ledgers);
- Proof of abuse, coercion, or deception (police reports, restraining orders, therapist notes, sworn statements);
- Divorce or separation documents that show changed financial ties.
Factors that often undermine claims:
- Clear evidence that the requesting spouse benefited from the undeclared income (luxury purchases, joint use of funds);
- Long history of joint earnings and joint control of money without any notice of problems;
- Signing multiple returns that show the same pattern without asking questions.
A practical note from my work: small financial red flags early—like unexplained deposits or newly opened accounts—are powerful when corroborated quickly. When clients wait years to gather evidence, memories fade and records disappear, making relief harder to obtain.
Timing and realistic processing times
File Form 8857 as soon as you suspect an issue. While the IRS does not always apply a single deadline across all relief types, timing can matter, especially if the IRS has already collected funds from you. The Form 8857 instructions and IRS Publication 971 discuss time limits and collection‑related rules; consult them and a tax pro promptly.
Processing time: expect several months. Many cases take 6–12 months for an administrative determination; complex cases or appeals take longer. If the IRS has already taken collection action against you, note that a timely Form 8857 can affect collection treatment.
(See IRS Publication 971 and Form 8857 instructions for specific time‑limit rules.)
What if the IRS denies relief?
You have appeal options:
- Request an administrative appeal within the IRS (Office of Appeals); follow the appeal instructions in the denial letter.
- Explore Collections Appeal Rights or the Collection Due Process (CDP) route if the case involves levies or liens.
- In some circumstances, you may seek judicial review after administrative options are exhausted. Consult a tax attorney early if you expect litigation.

Common mistakes to avoid
- Waiting too long to file Form 8857 or to collect evidence.
- Relying only on verbal explanations instead of contemporaneous documents.
- Confusing injured‑spouse relief (Form 8379) with innocent spouse relief (different purpose—injured‑spouse protects joint refunds from offsets against the other spouse’s past debts). See our comparison Form 8379 vs. Innocent Spouse Relief for details: https://finhelp.io/glossary/form-8379-vs-innocent-spouse-relief/
- Failing to ask for professional help when the facts are complex.
Practical tips (from practice)
- Document everything from the first sign of trouble. Bank statements, emails, texts, receipts, and contemporaneous notes are more persuasive than memory alone.
- Keep copies of tax returns and preparer worksheets. If a preparer made the error, their workpapers can help explain what happened.
- Consider a protective filing strategy if your situation is active: for example, submit Form 8857 promptly, and coordinate with counsel about staying collection actions while the claim is pending.
- If there’s abuse or coercion, gather corroborating evidence (medical records, police reports) and include a clear narrative with dates.
My experience: well‑organized packets—chronological, labeled, and succinct—move faster through IRS screening and make appeals stronger.
Example outcomes (illustrative)
- Approved innocent spouse relief: IRS allocates the understatement to the responsible spouse; the requesting spouse is relieved of the tax, interest, and certain penalties tied to the understatement.
- Equitable relief granted: IRS may abate tax, penalties, and interest to the extent deemed fair, sometimes splitting responsibility.
- Denial: the requesting spouse remains liable and must pursue appeals or repayment options; injured‑spouse remedies do not apply to innocence queries.
