I hear this more than you'd think: a marriage ends, and one spouse discovers the IRS considers them fully liable for a tax mess the other one created. A joint return means joint and several liability — the government can collect every dollar from either of you, and it goes after whoever is easier to find. The law's answer is innocent spouse relief under Section 6015, and it has three doors.
The Three Forms of Relief
Subsection (b) is classic innocent spouse relief: the understatement came from the other spouse's income or deductions, you didn't know and had no reason to know, and holding you liable would be inequitable. Subsection (c) lets divorced or separated taxpayers simply split the deficiency — you're responsible for your items, they're responsible for theirs. Both carry a two-year deadline that starts when the IRS first begins collection against you.
Subsection (f), equitable relief, is the safety net for everything else — including cases where the tax was reported correctly but never paid. The IRS weighs marital status, economic hardship, knowledge, and crucially, abuse and financial control. There's no two-year bar here; relief can be requested any time the collection statute is open.
What Wins These Cases
Facts, assembled like evidence — because that's what they are. Who handled the money. Who signed what, and under what circumstances. What a reasonable person in your position could actually have known. If the IRS says no, the case goes to Tax Court, where I'm admitted and where these denials get a genuinely fresh look.
You didn't create this liability. The law agrees you shouldn't automatically own it. Let's talk.
