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.
What if my payment is made after the due date?
Penalty accrues monthly at one percent of the tax due, and increases by an additional one percent per month, or fraction thereof (e.g., penalty on a $500 tax due will be $30 if the tax is unpaid for six months). The interest rate is 1 percent above the adjusted prime rate and is adjusted on January 1 and July 1 of each year. Interest is charged from the original due date of the return to the date the balance of the tax is paid. View current interest rates on Treasury’s Web site.
