Innocent Spouse Relief: Three Paths From Joint Tax Liability

Spouses who file a valid joint federal return generally become jointly and severally liable for the tax, interest, and penalties. The IRS may collect the joint liability from either spouse even after divorce. Section 6015 provides three distinct forms of relief, and the correct path depends on whether the problem is an understatement or an unpaid balance, who generated the item, what the requesting spouse knew, and the spouses' current relationship.

Section 6015(b): Innocent Spouse Relief

This relief generally applies to an understatement attributable to erroneous items of the other spouse. The requesting spouse must establish the statutory requirements, including lack of knowledge or reason to know and that, considering all facts and circumstances, holding that spouse liable would be inequitable. Partial relief may be possible when the spouse knew only part of an understatement.

Section 6015(c): Separation of Liability

This provision may allocate a deficiency between former spouses or spouses who are legally separated or who were not members of the same household during the applicable 12-month period. Actual knowledge of the item generally blocks allocation for that item, subject to statutory exceptions. This remedy addresses deficiencies and does not simply divide an unpaid balance shown correctly on the joint return.

Section 6015(f): Equitable Relief

Equitable relief may be available when relief is unavailable under the other provisions and, considering all facts and circumstances, it would be inequitable to hold the requesting spouse liable. It can apply to an understatement or to tax correctly reported but not paid. The IRS evaluates threshold conditions and equitable factors; no single hardship fact guarantees relief.

Form 8857, Notice, and Deadlines

Relief is generally requested on Form 8857. The IRS must notify the nonrequesting spouse and permit participation, although it should not disclose the requesting spouse's new address, phone number, employer, or other protected information. Sections 6015(b) and (c) generally use a two-year period measured from the IRS's first qualifying collection activity against the requesting spouse. Equitable-relief timing depends on the applicable collection or refund limitation period under current guidance.

A requesting spouse may have administrative appeal and Tax Court rights, but the procedural route and petition deadline depend on the IRS determination and the posture of the case. A divorce decree may create rights between former spouses but does not, by itself, release either spouse from federal joint liability.
