Why was my Investment Tax Credit (ITC) adjusted?If the ITC was adjusted on your Michigan Business Tax (MBT) return, check if the following information was included with return:
- The following forms are required to be filed to claim the ITC: Form 4567, Form 4568 and Form 4570. If any of these forms are missing, the credit will be denied. A complete amended return, including all forms, schedules and attachments, must be filed in order to correct the original return.
- All columns of each applicable table on Form 4570 must be fully completed if claiming that portion of the credit. A form with “Various” in the tables will not be accepted. If “See Attached” is entered, supplemental documentation must be provided with your return, showing detailed itemization.
