What's the Difference Between Innocent Spouse Relief and Injured Spouse Relief?

Innocent spouse relief and injured spouse relief sound similar but they address two completely different situations. Innocent spouse relief is for people who filed a joint return and later discovered that their spouse (or ex-spouse) underreported income or claimed improper deductions without their knowledge — it allows the innocent spouse to be released from liability for the resulting tax debt. Injured spouse relief is not about wrongdoing at all; it applies when the IRS offsets a joint tax refund to pay one spouse's pre-existing separate debt, such as student loans, past-due child support, or a prior-year tax debt. If you file a joint return and your refund is taken to pay your spouse's separate obligations, you can file Form 8379 as an injured spouse to claim back your share of the refund. Both forms of relief require filing a specific IRS form, but they apply in very different circumstances.
