Here's what each field means:
Annual Income is your total earnings before any taxes. Include wages, freelance income, investment income, and any other sources.
Filing Status determines which deductions and exemptions apply. Michigan uses filing statuses similar to the federal system.
Michigan Income Tax: What You Need to Know
Michigan uses a flat income tax of 4.25% on all taxable income. Unlike states with progressive brackets, everyone pays the same percentage regardless of how much they earn. A teacher making $45,000 and a CEO making $500,000 both pay 4.25%.
Michigan uses a flat 4.25% income tax rate on all taxable income. The state starts with federal AGI and applies personal exemptions of $5,600 per person (2025). Michigan doesn't use a standard deduction but the generous personal exemptions help offset this. One notable feature: Michigan fully exempts public pension income from state tax, and private retirement income gets partial exemptions depending on your birth year. Social Security is not taxed.
A Real Example
Let's say you're a single filer earning $65,000 in Michigan. Your approximate Michigan state income tax would be around $2,531, for an effective state tax rate of about 3.9%.
That's just the state portion. Federal income tax and FICA taxes are additional.
Deductions and Exemptions
Personal exemption of $5,600 per person. Public pension income is fully exempt. Private retirement income has various exemptions based on birth year and type. Michigan also offers a homestead property tax credit and an earned income tax credit (6% of federal EITC).
Local Taxes
Yes — 24 Michigan cities levy their own local income taxes. Detroit's rate is 2.4% for residents, the highest in the state. Other cities like Grand Rapids (1.5%), Lansing (1%), and Flint (1%) also levy city income taxes. Non-residents who work in these cities pay a reduced rate (typically half the resident rate).
Recent Changes
The personal exemption was increased significantly from $5,400 to $5,600 for 2025. Michigan temporarily reduced its rate to 4.05% for part of 2023 before reverting to 4.25%.
How to Use This Calculator Strategically
Model a raise or job change. With a flat tax, the math is simpler — every additional dollar is taxed at 4.25%. But deductions and credits can still shift your effective rate.
Compare filing statuses. Even with a flat rate, different filing statuses unlock different deduction amounts that can affect your bottom line.
Plan retirement contributions. See how 401(k) or IRA contributions reduce your Michigan taxable income and lower your state tax bill.
Evaluate a move. Compare Michigan's flat 4.25% rate to other states. Depending on your income level, a flat tax state might save you money — or cost you more — compared to a progressive system.
