Equitable relief is the third door in innocent spouse relief — the one that stays open when the other two close. Under §6015(f), if it would be inequitable to hold you liable for unpaid tax or a deficiency, and relief is not available under §6015(b) or (c), the IRS may relieve you of the liability — in full or in part. This page owns that route completely: its unique scope, the IRS framework that decides it (Rev. Proc. 2013-34), and the deadline that makes it different from everything else in the family. It is requested on the same Form 8857 as the other types.
General information, not tax or legal advice. Rules below are from 26 USC §6015(f) and Rev. Proc. 2013-34; equitable relief is discretionary and decided on your specific facts.
Section 6015(b) and §6015(c) reach understatements only — tax that should have been on the return but wasn’t. Equitable relief also reaches underpayments: tax that was correctly reported on the joint return but never paid. The Form 8857 instructions state it plainly — equitable relief is the only type of relief available for an unpaid tax. If your joint return was honest and the bill simply went unpaid by your spouse, (f) is not the fallback. It is the only door.
The (b) and (c) elections die 2 years after the IRS begins collection activities against you. Equitable relief runs on a different, longer clock, set by statute in §6015(f)(2):
These periods were IRS policy first (Notice 2011-70 in 2011, then Rev. Proc. 2013-34 §4.01(3)) and were codified by the Taxpayer First Act of 2019 (Pub. L. 116-25, §1203). Two warnings follow. First, older material — including old IRS web pages — still prints a 2-year deadline for (f); that rule has not been current since 2011. Second, the (f) clock is longer, not endless: once the §6502 period closes on an unpaid liability, the route closes with it.
Gate 1 — threshold conditions (Rev. Proc. 2013-34 §4.01). All must hold: a joint return was filed for the year; relief is not available under (b) or (c); the request is timely; no assets were transferred between the spouses as part of a fraudulent scheme; no disqualified assets were transferred to you; you did not file the return with fraudulent intent; and the liability is attributable to an item of — or an amount properly allocable to — your spouse, subject to the procedure’s stated exceptions.
Gate 2 — the streamlined determination (§4.02). If the threshold conditions are met and all three of these hold, the IRS will ordinarily grant relief outright: (1) you are no longer married to your spouse — divorced, legally separated, widowed, or not a member of the same household for the 12 months ending when the determination is made; (2) you would suffer economic hardship if relief is not granted; and (3) knowledge — for an understatement, you did not know and had no reason to know of the item; for an underpayment, you did not know and had no reason to know your spouse would not or could not pay the tax the return reported.
Gate 3 — the seven-factor weighing (§4.03). Miss any streamlined element and the request is weighed on all the facts and circumstances. The factors are nonexclusive and no single factor is dispositive:
Abuse and financial control are weighed inside the knowledge factor — and can outweigh knowledge itself: the revenue procedure’s stated purpose includes expanding exactly that consideration. Relief can also be partial: (f) can relieve any portion of the liability, so the weighing can end in a split rather than a yes or no.
A §6015 determination — including an (f) denial — can be petitioned to the U.S. Tax Court under §6015(e). Since the Taxpayer First Act of 2019 added §6015(e)(7), that review is de novo, based on the administrative record established at the time of the determination plus any newly discovered or previously unavailable evidence. The practical lesson lands earlier, at the form: build the complete factual record in your Form 8857 statement, because the court largely reviews what the IRS had. The petition deadlines and the road to them are in the Form 8857 walkthrough.
Can equitable relief help if the tax was reported correctly but never paid? Yes — that is its distinctive reach. Equitable relief under §6015(f) can be granted for liabilities correctly reported on the return but not paid, as well as for deficiencies. Sections 6015(b) and (c) cannot touch an underpayment at all.
What factors does the IRS weigh for equitable relief? The seven Rev. Proc. 2013-34 §4.03 factors: marital status; economic hardship; knowledge or reason to know; legal obligation under a divorce decree or agreement; significant benefit beyond normal support; subsequent compliance with the tax laws; and the requester’s mental or physical health. None is individually decisive, and abuse or financial control is weighed within the knowledge factor.
Is there a deadline for equitable relief, or can I file any time? There is a deadline — it is just not the 2-year clock that governs (b) and (c). Under §6015(f)(2), a request for an unpaid liability must be made before the §6502 collection period expires (generally 10 years from assessment); a request involving tax already paid must fall within the §6511 refund-claim period.
