Michigan State Income Tax: 2026 Rate, Exemptions & City Tax Rules
Michigan keeps it simple: one flat rate, no brackets to climb. But “simple” hides two quirks that catch newcomers off guard. First, Michigan offers no standard deduction — instead, a $5,900-per-person personal exemption does all the work. Second, your state tax bill may not be your full bill: about two dozen Michigan cities, including Detroit at 2.4%, levy their own income tax on top.
This guide answers the questions Michigan taxpayers actually search for: the 2026 flat rate, how the exemption system works, which cities add their own tax, and how Michigan stacks up against Ohio and Illinois. Run your own numbers with the free Michigan income tax calculator.
What is Michigan’s income tax rate in 2026?
Michigan taxes all taxable income at a flat 4.25% in 2026 — no brackets, no tiers. Every dollar of Michigan taxable income (after subtracting your personal exemptions) is taxed at the same 4.25% rate. The rate has been stable since 2023, when it temporarily dipped to 4.05% for one year under a state revenue trigger before returning to 4.25%.
Why doesn’t Michigan have a standard deduction?
Michigan is one of the few states that simply doesn’t offer a standard deduction. Instead, it relies on the personal exemption — $5,900 per person in 2026 — to shield your first dollars from tax. A single filer subtracts $5,900; a married couple filing jointly subtracts $11,800; each dependent adds another $5,900. The exemption is adjusted for inflation every year by the Michigan Department of Treasury.
The practical effect is similar to a standard deduction for most filers, but with one difference: the exemption grows with household size, so larger families get proportionally more relief. A couple with two children shields $23,600 before the 4.25% rate touches a dollar. Test your household with the Michigan income tax calculator.
Do I owe city income tax in Michigan?
You might — and this is Michigan’s biggest tax gotcha. About two dozen cities levy their own income tax. Detroit charges 2.4% on residents and 1.2% on nonresidents who work in the city; Grand Rapids, Flint, Lansing, and others charge 1% on residents (typically 0.5% on nonresidents). A Detroit resident earning $80,000 pays roughly $1,920 in city tax on top of about $3,149 in state tax — the city layer adds more than 60% to the bill.
City tax is usually withheld by your employer if you work in a taxing city, and cities generally don’t give you a credit against the state tax — it’s purely additive. If you live or work in a Michigan city, add its rate to your state estimate.
How does Michigan’s tax compare to Ohio and Illinois?
It depends on your income and your city. Michigan’s flat 4.25% sits between Ohio’s effective 2.75% (above its $26,050 zero bracket) and Illinois’ flat 4.95%. Because Michigan has no standard deduction, low-income filers can face a slightly higher effective rate than in Ohio — but the generous $5,900-per-person exemption keeps Michigan competitive at middle incomes.
The real differentiator is the city layer: Ohio’s cities and Michigan’s cities both add local tax, while Illinois has none. A Chicago resident’s state-only number is the whole story; a Detroit resident’s is not. Compare all three with the Michigan income tax calculator, the Ohio calculator, and the Illinois calculator.
Does Michigan tax retirement income?
Partially. Michigan fully exempts Social Security benefits and offers a “pension subtraction” that shields a portion of pension and retirement-plan income — the limits vary by your age and birth year, with more generous treatment for older retirees. IRA and 401(k) distributions generally qualify for the subtraction up to the limit. If you’re retired or near it, verify the current subtraction rules with the Michigan Department of Treasury before estimating.
Worked example: $80,000 salary (single, Detroit resident)
- Gross wages: $80,000
- Personal exemption (single): −$5,900
- Michigan taxable income: $74,100
- State tax (4.25% × $74,100): $3,149.25 (3.94% effective)
- Detroit city tax (2.4% × $80,000): $1,920.00
- Combined state + city: $5,069.25 (6.34% effective)
Outside a taxing city, the bill is just the $3,149.25 state portion. The city layer is why “Michigan’s 4.25% rate” can be a misleading comparison for Detroit-area workers.
Frequently Asked Questions
What is the Michigan personal exemption for 2026?
$5,900 per person — $5,900 for a single filer, $11,800 for a married couple filing jointly, plus $5,900 per dependent. It’s adjusted annually for inflation by the Michigan Department of Treasury.
Which Michigan cities have an income tax?
About two dozen, including Detroit (2.4% residents / 1.2% nonresidents), Grand Rapids, Flint, Lansing, Saginaw, and others — most charge 1% on residents and 0.5% on nonresidents who work there. Check with your city’s income tax office to confirm the current rate.
Can I deduct my city income tax on my Michigan return?
No — Michigan does not allow a credit or deduction for city income tax paid against your state liability. The city tax is purely additive to the state tax, which is why Detroit residents face a notably higher combined burden.
When is my 2026 Michigan return due?
April 15, 2027. Michigan individual returns (Form MI-1040) follow the federal deadline. City returns have their own forms and deadlines — Detroit’s, for example, is administered separately, so confirm yours directly.
Is Michigan’s rate really 4.25% if it dropped to 4.05% before?
Yes, 4.25% for 2026. Michigan’s rate temporarily fell to 4.05% for tax year 2023 under a state law that triggered a cut when general fund revenue exceeded a threshold. The state supreme court later ruled the cut was one year only, and the rate returned to 4.25% for 2024 onward.
How do I estimate my Michigan tax for 2026?
Use the free Michigan income tax calculator with the 4.25% rate and $5,900 exemption built in. Remember it models the state portion only — add your city’s rate (if any) for the full picture.
