Software Developer Secure Web Site for Substitute Forms and Electronic Filing

Michigan Treasury Updates

 

Tax Year 2017 Form 4430 is available here. Developers must submit Form 4430 to Treasury to obtain access to the State Exchange System. Form 4430 can be submitted to MIFormsEfile@michigan.gov

Once your company’s 4430 is processed, your company will receive an e-mail from Support@taxadmin.org  which will provide you access to the approved folder(s) with the State Exchange System site.

Michigan Department of Treasury will post all e-file and form information to the State Exchange Site. Treasury will maintain use of this Web site for Tax Year 2017 ESA-related materials.

Software developers should reference the Substitute Forms Submissions Manual for guidelines on submitting substitute forms. Software developers are not to submit forms for testing until forms are posted as “Final Drafts.”
