Because Treasury has started issuing the expanded Michigan EITC supplemental check payments for tax year 2022, it is no longer necessary to view or manually update your address. If you moved between last year and now, please be sure your new address is on your 2023 individual income tax return filing.
Calculate Late Penalty and Interest
The Revenue Act includes provisions for charging penalty and interest if a taxpayer fails to pay a tax within the time specified.
Interest is calculated by multiplying the unpaid tax owed by the current interest rate.
Penalty is 5% of the total unpaid tax due for the first two months. After two months, 5% of the unpaid tax amount is assessed each month. The maximum late penalty is equal to 25% of the unpaid tax owed.
