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.
