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.
Why is my return reviewed every year?
All returns are subject to a manual review by the Michigan Department of Treasury.
Selection for review in one tax year does not increase or decrease the chance of your return being selected in future years.
Michigan law prevents the Department from discussing specific criteria for review of returns. If the review results in an adjustment to your return, you will receive a letter of explanation.
