An Iowa partnership or S Corporation is not required to submit K-1 information on a CD or electronically using our Secure File Exchange (SFE) program. If you choose to submit K-1 information using either of these methods, the information must be in the ASCII format in a specific layout. You can access the approved layout for partnerships or S Corporations and formatting instructions. Any layout other than the posted approved format, must have Department approval before submission.
Either option still requires an IA1065 or IA1120S to be filed. Although a copy of the federal return should be attached, copies of the federal K1 will not be necessary.
On the Iowa return:
- Sign the return at the bottom of the page.
- Mail to:
Tax Management Division
Iowa Department of Revenue
PO Box 10456
