Iowa Return Mailing Addresses
When filing your Iowa state income tax return, it is important to use the correct mailing address based on your filing status and whether you are submitting a paper return or e-filing. The Iowa Department of Revenue provides specific addresses for different types of returns.
General Mailing Address for Paper Returns
For most individual taxpayers filing Form IA 1040 or other Iowa state tax forms by mail, use the following address:
- Iowa Department of Revenue
- PO Box 1010
- Des Moines, IA 50304-1010
Specialized Forms and Addresses
Certain forms may require different mailing addresses. For example:
- Form IA 100G (Capital Gain Deduction for Retired Farmers) – Use the general address above unless otherwise specified in the form instructions.
- Form IA 128 (Iowa Research Activities Credit) – Also mailed to the general address unless otherwise indicated.
- Form IA 4136 (Fuel Tax Credit) – Same general address applies.
Important Notes
- Always check the specific instructions for your form to confirm if a different mailing address is required.
- Ensure your return is postmarked by the Iowa state tax deadline, typically April 15, unless extended.
- E-filing is encouraged and available through the Iowa Department of Revenue’s online portal.
