Michigan State Income Tax Overview
Michigan has a flat state income tax rate of 4.25% for all taxpayers. The rate briefly dropped to 4.05% for tax year 2023 under a one-year revenue trigger, then reverted to 4.25% for 2024 and remains there. Michigan has no standard deduction but offers a personal exemption of $5,800 per filer and per dependent. Twenty-four Michigan cities levy their own income tax, including Detroit at 2.4% for residents and 1.2% for non-residents who work in the city. Michigan is phasing in a restoration of the retirement income exemption, which reduces or eliminates state tax on pension income for a growing share of retirees each year.

Understanding Your Michigan Tax Estimate
Your results combine two separate bills: federal tax owed to the IRS, and Michigan state tax owed to the Michigan Department of Treasury. The state return is filed separately from your federal Form 1040, with a state filing deadline of April 15. For the mechanics of how bracket math actually works -- why your effective rate is almost always lower than your top bracket -- see our marginal vs. effective tax rate guide.
Lowering Your Michigan Bill
Pre-tax retirement contributions reduce your federal and Michigan taxable income in the same move -- see our 401(k) contribution limits and HSA limits guides for the current caps. Beyond that, Michigan-specific credits and deductions that don't exist at the federal level are listed at the Michigan Department of Treasury -- worth checking, since these are easy to miss if you only look at federal guidance.
Combined Sales + Income Tax Picture
