K-1 S Corporation Information on CD

K-1 S corporation information on a CD must be in the ASCII format in a specific layout. Here are the links for the approved layout (pdf) and formatting instructions.

The S corporation will still need to file the IA 1120S and include the CD with the return.

On the IA 1120S:

  • Complete page 1 only (except Schedules S and K),
  • Write “See attached CD” and
  • Sign the return at the bottom of the page.
  • Mail to:

    Russ Shumate
    Compliance Services, Tax Management Division
    Iowa Department of Revenue
    PO Box 10456
    Des Moines, IA  50306-0456
    Email:  Russ Shumate
    phone:  515-242-6847 

The information in Schedule S, Schedule K, and page 2 will be obtained from the CD.

If the CD is not in the Department's approved format, the return will be considered incomplete until a correct CD or complete paper return is filed.

If you have questions about this procedure, contact Stephen Breeden at 515-242-0173 or Email Stephen Breeden.
