Innocent Spouse Relief

Innocent spouse relief releases you from a federal tax debt that belongs to your spouse or former spouse. It exists because a joint return makes both signers liable for the entire balance, and the IRS may collect all of it from whichever spouse is easier to reach, a rule that outlives the marriage.

A divorce decree assigning the tax debt to your former spouse binds the two of you, not the IRS, which can still garnish your wages over income you never saw or levy your account over a deduction you did not take. Internal Revenue Code Section 6015 is the exception: relief, once granted, lifts the tax and the related interest and penalties off you and leaves the liability with the other spouse.

Denials are usually procedural rather than unsympathetic. The wrong subsection gets requested, the deadline gets miscalculated, or the file never documents what the requesting spouse actually knew on the day the return was signed. The IRS gives you one administrative determination per assessment, so the first submission is the one that counts.

The four types of innocent spouse relief

Section 6015 contains three forms of relief. Section 66(c) adds a fourth, parallel route that reaches unreported community income and does not require a joint return at all. Form 8857 covers the three Section 6015 forms at once, and the IRS is expected to consider each one your facts could support. Naming the right subsection is not a filing requirement, but knowing which one fits changes what evidence the request needs.

Traditional relief, Section 6015(b)

This is the original form and the only one open to spouses who are still married and living together. Five elements must all be satisfied: a joint return was filed; an understatement of tax is attributable to erroneous items of the other spouse; you did not know and had no reason to know of the understatement when you signed; holding you liable would be inequitable; and you elect relief within two years after the IRS begins collection activity against you.

The elements are conjunctive, so failing one ends the analysis, and the third defeats most requests. Reason to know is a constructive standard measured by what a reasonably prudent person in your position would have understood. A large unexplained jump in household spending, access to the account where unreported income landed, or involvement in the business that generated it can each supply reason to know even without actual awareness.

Section 6015(b) reaches understatements only. If the return reported the tax correctly and the two of you simply did not pay it, this subsection cannot help. Partial relief is available under Section 6015(b)(2) when you knew about some of the understatement but not the rest.

Separation of liability, Section 6015(c)

Rather than releasing you outright, Section 6015(c) splits the deficiency and holds you responsible only for the share allocable to you, calculated roughly as though the two of you had filed separately. Where the deficiency traces entirely to your spouse's items, that share can be zero.

Eligibility turns on marital status. You must be divorced, legally separated, or not a member of the same household at any time in the twelve months ending on your filing date, and widowhood counts: the Tax Court held in 2023 that a widowed spouse qualifies as no longer married for this purpose.

The knowledge standard here is friendlier than under Section 6015(b), and it is the most underused feature of the statute. Only actual knowledge of the item giving rise to the deficiency defeats relief, and the Tax Court has held that compiling the tax documents and signing the return shows constructive knowledge without establishing actual knowledge. The burden also runs the other way: the IRS must prove actual knowledge rather than you having to disprove it.

Two limits apply. Section 6015(c) reaches deficiencies only and produces no refund, so a refund claim needs Section 6015(b) or Section 6015(f). Your allocated share also increases by the value of any disqualified asset your spouse transferred to you to avoid tax, and transfers within the year before the first proposed deficiency letter are presumed to have that purpose unless made under a divorce decree.

Equitable relief, Section 6015(f)

Section 6015(f) is the residual provision, available only where Section 6015(b) and Section 6015(c) are not. It is the only route that reaches underpayments, where the return was accurate and the tax simply went unpaid, and it carries no two-year deadline, discussed below.

No statutory knowledge test applies here. The IRS instead weighs the facts and circumstances under Revenue Procedure 2013-34, which supplies threshold conditions, a streamlined path to automatic relief, and eight weighted factors, discussed further down this page. You carry the burden of proof.

Community property relief, Section 66(c)

Section 66(c) is a separate provision for spouses in community property states who left an item of community income off a return. It sits outside Section 6015 and does not require that a joint return was filed, which means it can reach a spouse who filed separately. Revenue Procedure 2013-34 governs these requests using the same equitable factors, though the first two threshold conditions drop away.

This route rarely applies to clients in the firm's footprint, since Maryland, Virginia, the District of Columbia, Delaware, New York, North Carolina, New Jersey, Florida and Kentucky are all common law jurisdictions. It becomes relevant when the income or the marriage connects to a community property state, which happens more often than expected among military families, relocated households, and spouses who lived apart across state lines.

Innocent spouse vs. injured spouse relief

These two get conflated constantly. Innocent spouse relief, requested on Form 8857, is about liability: you are being held responsible for tax that arose from your spouse's items or your spouse's failure to pay, and you want off that liability. Injured spouse allocation, requested on Form 8379, is about a refund the IRS applied to your spouse's separate debt. The test is short: ask whether the question is who owes this, or where did my refund go.

Deadlines for filing innocent spouse relief

Traditional relief and separation of liability must be elected within two years after the IRS begins collection activity against you, and what counts as collection activity is defined narrowly. A notice of intent to levy carrying collection due process rights starts the clock, as does an offset of your own overpayment against the joint liability, and so does a collection suit or claim filed against you or your property.

A notice of deficiency does not start the clock, and neither does the filing of a Notice of Federal Tax Lien or an ordinary notice and demand for payment. Taxpayers routinely assume they are years out of time because a lien was recorded long ago, when the two-year period never began at all.

Equitable relief carries no two-year deadline. The regulation that once imposed one was struck down by the Tax Court, upheld by several courts of appeals including the Fourth Circuit, and then abandoned by the IRS in Revenue Procedure 2013-34. What governs now is the collection statute expiration date, generally ten years from assessment, for relief from an unpaid balance, and the Section 6511 refund period, generally three years from filing or two years from payment, if you want money back.

A floor applies as well as a ceiling: the IRS will not consider a request filed for a tax year before you have received an audit notice or another letter indicating there may be an outstanding liability for that year. And because you are entitled to only one final administrative determination per assessment, a thin initial submission is not something you can simply redo.

How the IRS evaluates an equitable relief request

Revenue Procedure 2013-34 structures the analysis in three stages. Seven threshold conditions come first, and all must be met:

• A joint return was filed
• Relief is unavailable under Section 6015(b) or Section 6015(c)
• The request is timely
• No assets moved between spouses as part of a fraudulent scheme
• Your spouse transferred you no disqualified assets, or relief is limited accordingly
• You did not knowingly participate in filing a fraudulent return
• The liability traces at least in part to your spouse's erroneous item or underpayment

Clearing those opens the streamlined determination, an effectively automatic grant requiring that you are no longer married, that you would suffer economic hardship without relief, and that you did not know or have reason to know of the understatement or, in an underpayment case, that your spouse would not pay. Economic hardship carries benchmarks: income below 250 percent of the federal poverty guidelines favors relief, as does income above that level where monthly income exceeds reasonable living expenses by 300 dollars or less.

Where the streamlined path is closed, the IRS weighs eight non-exclusive factors:

• Marital status
• Economic hardship
• Knowledge or reason to know
• Whether a divorce decree or agreement placed the liability on your spouse
• Whether you significantly benefited from the unpaid tax
• Your compliance with tax law in later years
• Your mental or physical health
• Abuse or financial control by your spouse

No single factor controls and no majority of factors controls, and the weight each carries shifts with the facts. One item on that list is still within your control after the marriage ends: staying current on your own filings weighs in your favor, and ongoing noncompliance weighs against you for no good reason.

Knowledge, abuse and financial control

Knowledge is the contested issue in most cases, and the standard is not uniform. Section 6015(b) asks whether you knew or had reason to know, a constructive test you must overcome. Section 6015(c) asks only about actual knowledge and puts the burden on the IRS. Section 6015(f) treats knowledge as one factor among eight.

Abuse and financial control cut across all three, and the treatment is asymmetric. The equitable framework under Revenue Procedure 2013-34 considers both abuse and financial control by the non-requesting spouse, but Section 6015(b) recognizes an exception for abuse and not for financial control. The Tax Court applied that distinction in a 2023 decision, holding that the requesting spouse's access to a joint bank account defeated the claim under Section 6015(b), then granting partial equitable relief under Section 6015(f) because the other spouse nonetheless exercised financial control.

The practical consequence is procedural: where abuse or financial control is present, the request should be built for Section 6015(f) from the outset rather than treated as a fallback, and the evidence of control has to be documented, including who held the accounts and who was permitted information about household finances.

How to file Form 8857

Relief is requested on Form 8857, Request for Innocent Spouse Relief. The single form covers all three Section 6015 subsections, and the IRS is to treat it as a request under each that applies. Two things follow immediately.

The IRS is required by statute to notify your former spouse that you have requested relief and give that person an opportunity to participate. No confidential version of this process exists, and should the case reach the Tax Court, the non-requesting spouse has a statutory right to intervene. The IRS will not disclose your address or employer, but your former spouse will learn the request exists, which is why safety planning belongs before the filing in cases involving abuse.

Collection also stops. Once relief is requested, the IRS generally may not levy or bring a collection proceeding against you until the determination is final, and where a Tax Court petition follows, until that decision is final. One limit is worth knowing: where a court has already entered a final decision for the same tax year, that decision is generally conclusive except as to relief not at issue in the earlier proceeding, and even that exception disappears if you participated meaningfully in the prior case.

If the IRS denies your request

You may petition the United States Tax Court after the IRS mails a notice of final determination, or after six months pass with no action on your request, whichever comes first. Where a final determination issues, the petition is due no later than the 90th day after it was mailed, and that window is unforgiving.

The standard of review favors taxpayers. Section 6015(e)(7), added by the Taxpayer First Act of 2019, directs the Tax Court to review innocent spouse determinations de novo, based on the administrative record plus any newly discovered or previously unavailable evidence, deciding the question fresh rather than asking whether the IRS abused its discretion. The provision governs petitions filed on or after July 1, 2019, and requests pending with the IRS on that date.

Innocent spouse relief can also be raised inside a collection due process hearing, and where it is, the resulting determination counts under both the collection due process rules and Section 6015, giving the Tax Court independent jurisdiction over the innocent spouse portion. The court confirmed in 2025 that this holds even where the collection due process petition itself was untimely. Because review runs on the administrative record, what you submit to the IRS shapes what the court is later permitted to see.

Why Whiteford

Section 6015 cases turn on two decisions made long before the IRS rules: which subsection to pursue, and what goes into the administrative record. Both are difficult to repair later, since the Tax Court reviews the determination on that record plus only evidence that was genuinely unavailable earlier.

Whiteford's tax controversy attorneys represent clients through IRS examination, administrative appeals, and litigation in the United States Tax Court and the federal district courts. The group's collections work covers levies, liens, installment agreements and offers in compromise, which is the same ground a Section 6015 request crosses whenever collection has already started. Michael March leads the practice.

The firm practices from offices in Maryland, Virginia, the District of Columbia, Delaware, New York, North Carolina, New Jersey, Florida and Kentucky. Most of that footprint sits in the Fourth Circuit, which was among the courts that upheld the two-year regulatory deadline for equitable relief before the IRS abandoned it, so mid-Atlantic practitioners have specific reason to be careful about which deadline attaches to which subsection.
