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.
Is there penalty and interest due on a late filed return?
Late fiduciary payments are subject to a penalty of 5 percent of the tax due. After the second month, penalty will increase by an additional 5 percent per month, or fraction thereof, up to a maximum of 25 percent of the tax due. If the fiduciary payment is late, compute and add the applicable penalty and interest to the amount due. View latest interest rates.
