Iowa tax forms:
The Iowa Department of Revenue is pleased to provide draft versions of Iowa tax forms for software and substitute forms developers. Drafts will be posted on this Web site as they are available. The Department intends to post forms which are in varying degrees of development. All drafts will be posted with a "last revised" date. It is the user's responsibility to recognize that forms may change substantially.
Except for special cases and as requested, you will send us copies of the final versions -- not drafts -- of your substitute forms.
Everything you need to become approved to produce substitute Iowa forms is at this site. If you discover errors or have questions about any Iowa tax form, please contact us by e-mail (idrsubforms@iowa.gov). To receive the ID and password to the development area, you need to complete and submit the Registration for Substitute Forms Approval (pdf).
Chapter 8 (pdf) of the Iowa rules and regulations provides guidelines related to the approval process.
Software Developers:
The Department offers electronic filing of individual and business income tax returns. Specifications and test cases are available in the secured development area.
