Iowa Tax Filing

For State of Iowa tax purposes, international students and scholars who live and study in Iowa are generally considered residents of Iowa. If you had income from both Iowa and another U.S. State during 2024, you must complete Form IA1040 as well as Form IA126. You may also want to choose “married filing separately” if you and your spouse both worked during 2024. Choosing this option may reduce the amount of Iowa tax your family must pay.  

The filing deadline for 2024 Iowa tax returns is April 30, 2025.

Other State Tax Filing

All but nine (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming) of the 50 U.S. States have income tax return requirements.

If you worked in a U.S. State other than Iowa during 2024 you must file the appropriate tax form for the particular state in which you worked. Consult the Federation of Tax Administrators website to access tax forms for every U.S. state.

If you worked in more than one U.S. State during 2024, special part-year resident rules apply for each State that has an income tax. Carefully read and follow the instructions for part-year residents on the tax forms for both states.
