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.
E27. If an MBT return and attachments exceed the file size limitations, would Michigan prefer to receive the return electronically, without attachments, or would it be better to send a paper MBT return with attachments?
A paper return should be filed with a completed Form 4833, Michigan Business Tax E-file Exceptions, attached to the front. Form 4833 will be generated by your software.
