E21. Will all software companies be required to support MBT e-file?

Yes. If they do not support MBT e-file for the eligible forms that are included in their software package, we will not accept their paper returns unless they meet the criteria of one or more of the Treasury- recognized exceptions on Form 4833, Michigan Business Tax E-file Exceptions. Form 4833 will be generated by your software.
