E1. Will I be able to send attachments with the MBT e-file return?
Yes. Treasury will accept certain Portable Document Format (PDF) attachments
with MBT e-filed returns. A list of defined attachments is available on the
e-file Web site at www.MIfastfile.org
(select Business Taxpayer). You will need to follow your software instructions
for submitting attachments with an e-filed return.
