Michigan's income tax is a flat 4.25% on all taxable income, with no brackets, no graduation, and no distinction between earned and investment income at the state level. Every resident pays the same rate regardless of earnings. Some municipalities add a local income tax on top — Detroit's 2.4% resident surcharge is the highest in the state, while many smaller cities charge 1%. For the median earner at $72,389, the base state tax bill runs about $3,076 before the personal exemption, which Michigan allows at $5,000 per taxpayer. Retirement income has partial protection depending on birth year, and the state exempts Social Security entirely. On the federal side, Michigan residents at median income typically land in the 22% federal bracket, making the combined marginal rate around 26.25% before local taxes. Michigan also has no city payroll tax outside of those municipal income levies. Use the tax bracket calculator to map your Michigan income against both state and federal obligations.
Michigan Tax Brackets Explained (2026)
Michigan has a state income tax with a top marginal rate of 4.25%. On top of federal rates (10%–37%), residents can face a combined marginal rate exceeding 35% at higher income levels. However, your effective rate is always lower than the marginal rate because only income above each threshold is taxed at that bracket's rate.
The median household in Michigan earns $72,389/year. At that income (single filer), the federal effective rate is approximately 12–14%, bringing total income tax (federal + state) to roughly 15–17%.
How Marginal vs. Effective Rate Works
The marginal rate is the rate on your last dollar of income — it does not apply to all income. The effective rate is your total tax divided by total income. For example, someone earning $100,000 in Michigan has a 22% federal marginal rate but an effective federal rate of roughly 15%, because the first $44,725 (2024) is taxed at 10% and 12%, not 22%.
