The Injured spouse designation is not recognized by the State of Iowa when using married filing a joint return, filing status 2, or married filing separately on a combined return, filing status 3.
If your spouses refund will be used to pay a Federal, state, county or city debt, you must use the IA 1040 Long Form, filing status 4, married filing separate returns to prevent your refund from being applied to your spouses debt.
Examples of "debt" include unpaid child support, college
loans, tax, court fees and fines, and overpayments of ADC/FIP, food
stamps, and unemployment.
