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.
I filed my Michigan individual income tax return MI-1040 without claiming the tax year 2020 federal Unemployment Compensation Exclusion. If I qualify for a refund on my amended MI-1040, will I receive interest?
Interest on any refund will begin to accrue 45 days after the amended return is received or the date the return is due, whichever is later.
