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.
Notice of Proposed Income Tax Adjustments
This notice was sent because the Internal Revenue Service (IRS) made adjustment(s) to a prior year federal return. This resulted in an additional tax due on your Michigan return. Refer to the back of the notice for a list of the adjustments.
Any payment you submitted to the IRS does not affect the amount due to the Michigan Department of Treasury.
