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 Adjustment - Amended Return
This notice was sent because the Internal Revenue Service (IRS) audited a prior year federal return and reported the results to the Michigan Department of Treasury. This resulted in additional tax due on your Michigan return.
Any payment you submitted to the IRS does not affect the amount due to the Michigan Department of Treasury.
