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.
