What is the michigan state tax on early withdrawal on 401k?

In Michigan, early withdrawals from a 401(k) are subject to state income tax at the individual's marginal tax rate. Additionally, if the withdrawal occurs before the age of 59½, it may incur a federal penalty of 10%, though Michigan does not impose a separate state penalty on early withdrawals. It's important to consult a tax professional for specific guidance based on individual circumstances.
