File Iowa Form IA 126
Prepare Iowa Form IA 126 now with TaxAct
Form 126 is a supplemental form to Form-1040. As such it is not required that you file this form, and if you do file this form, you must attach it to your Form-1040 in your tax return. Form-126 allows Iowa part-year and non-residents to calculate the amount of income that is deemed "Iowa Income" and is taxed by Iowa. This form is important because Form-1040 taxes asks and taxes all income you earned. If you are a part-year or non-resident of Iowa chances are your state of residency will tax your income. Thus Form-126 allows you to avoid facing dual taxation by telling Iowa which income it can tax and what income it can't.
