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.
Letter of Inquiry Concerning Individual Income Tax
This letter was sent for one of the following reasons:
- The Adjusted Gross Income (AGI) reported on your Michigan Individual Income Tax Return MI-1040 may be understated. The AGI reported on your Michigan return should match the AGI reported on your federal return. The difference may result in additional tax due.
- The date of birth reported on the Michigan Pension Schedule (Form 4884) for you (and/or your spouse if applicable) does not match our records. This may result in additional tax due.
