According to the Note in the FORM L-1040, PAGE 1, INSTRUCTIONS section of LANSING INDIVIDUAL INCOME TAX FORMS AND INSTRUCTIONS, found at Individual Tax Forms | Lansing, MI - Official Website:
Schedules, attachments and other documentation that support tax withheld, exclusions, adjustments or deductions must be provided. Failure to attach or attaching incomplete supporting information will delay processing of your return or result in tax withheld, exclusions, adjustments or deductions being disallowed.
There are a number of instances in which the taxpayer is required to attach certain items, but no overall list. The best way to see what needs to be filed is to search “attach” in the instructions.
