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 Penalty and Interest for Underpaid Estimates
This notice was sent because you did not make the required estimated payments. The Michigan Income Tax Act requires taxpayers to make quarterly estimated payments if the income tax liability will be $500 or more after credits and withholding.
To avoid penalty and interest for underpaid estimates, your total tax paid through credits and withholdings must be:
- 90% of your current year's tax liability or
- 100% of your previous year's tax liability or
- 110% of your previous year's tax liability if your previous year's adjusted gross income is more than $150,000 ($75,000 for married filing separate)
