Scammers are contacting taxpayers while pretending to be from the Michigan Department of Treasury, using out‑of‑state phone numbers. They may request payments or attempt to trick you into providing your bank account information. Always verify the source before sharing any personal or financial details.
E11. Is there a penalty for failing to comply with the MBT e-file mandate?
Treasury will not accept the paper filing of a computer-generated MBT return that is eligible for e-file. If a preparer or taxpayer submits a computer-generated paper MBT return that is eligible for e-file, Treasury will not process the return and notification will be mailed to the taxpayer. Payment received with a paper return will be processed and credited to the taxpayer's account even when the return is not processed.
