Filing Requirements 24. Will I be able to e-file my Corporate Income Tax Return?
Yes. All eligible CIT returns prepared using tax preparation software or computer-generated forms must be e-filed. Treasury will not process computer-generated paper returns that are eligible to be e-filed. A notice will be mailed to the taxpayer indicating that their return was not filed in the proper form and content and must be e-filed. Payment received with a paper return will be processed and credited to the taxpayer's account even when the return is not processed.
Additional information will be published on Treasury's Web site as it becomes available. E-file information is available at www.MIfastfile.org.
