The Michigan Department of Treasury has been made aware that some "Reminder of Tax Due" letters sent to taxpayers contain an incorrect toll-free (1-800) TTY number, which may connect callers to a potential scam. Taxpayers with questions regarding unpaid individual income taxes are asked to contact the Treasury directly at 517-636-4486. We apologize for any confusion or concern this may have caused.
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.
