Innocent Spouse Relief — IRS Tax Debt Protection for Spouses — Definition Glossary

Full Definition

Innocent Spouse Relief (IRC Section 6015) allows a spouse to be relieved of responsibility for a tax liability reported on a joint income tax return when the erroneous items were attributable to the other spouse. For business owners who file jointly with a spouse who operated the business, innocent spouse relief can be critical — if the business generated unreported income or false deductions, the non-business spouse may seek relief from the resulting tax debt. There are three types: Traditional Innocent Spouse Relief (for understated tax due to erroneous items of the other spouse), Separation of Liability (allocates the understated tax between spouses), and Equitable Relief (when the other two types are unavailable but it would be inequitable to hold one spouse liable). Innocent spouse relief must be requested within two years of the IRS first attempting to collect from the requesting spouse. It does not eliminate the underlying debt — only shifts who is responsible for it.
