Bonus Tax Calculator — Michigan (2026)
Bonuses in Michigan are taxed as supplemental wages: the employer usually withholds a flat 22% federal, plus 7.65% FICA and Michigan state withholding. Withholding is not the final tax; the true cost is settled on your return. Enter your bonus to see both. Michigan uses a flat personal income tax of 4.25% applied to taxable income after a state standard deduction of $0.

The gross bonus before withholding.
Percentage method vs aggregate method
Under the percentage method the bonus is separated from regular pay and hit with the flat 22% federal rate (37% above $1 million of supplemental wages in a year). Under the aggregate method the employer combines the bonus with your normal check and withholds at your marginal rate — which can temporarily withhold far more than 22%.
Either way the bonus is ordinary income. If your marginal federal bracket is 24% or higher, the 22% flat withholding leaves you short at filing time; if you are in the 12% bracket, you are over-withheld and get it back as a refund.
The Michigan layer on bonuses
Michigan taxes bonus income at the same flat rate as salary — up to 4.25%. A $10,000 bonus therefore carries roughly $425 of Michigan tax at the top rate, on top of federal and FICA.
24 Michigan cities levy a local income tax (Detroit 2.4% residents / 1.2% non-residents; Grand Rapids 1.5% / 0.75%).
Reducing the tax on a Detroit bonus
Deferring part of the bonus into a 401(k) or HSA cuts federal and Michigan income tax immediately, though FICA still applies. Some employers allow a separate bonus deferral election — ask payroll before the payment date, not after.
Timing matters too: pushing a bonus into January shifts the tax year, useful if this year included unusually high income from automotive work or an equity event.
Local and payroll taxes Michigan adds on top
Detroit and 23 other Michigan cities levy a local income tax, up to 2.4% for residents. That deduction sits outside the federal and state income tax lines, so build it into your own budget on top of the numbers above.

Bonuses are wages, so every local layer that applies to your regular Michigan paycheck applies to the bonus too — which is why a supplemental payment often nets a smaller share than your salary does.
Working across a state line from Michigan
Michigan holds income-tax reciprocity agreements with Illinois, Indiana, Kentucky, Minnesota, Ohio and Wisconsin. If you commute between them, your wages are taxed only by your state of residence — file the exemption certificate with your employer so the wrong state is not withheld from every paycheck.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Detroit resident spending part of the year at a client site in Ohio may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Michigan tax bill
Michigan charges a 6% state sales tax, homeowners pay an average effective property tax of 1.38% of market value, and the minimum wage in force during 2026 is $13.73 an hour.
6% statewide with no local sales tax.
Income tax is only one part of a state's take. Michigan recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. Michigan is phasing back a full pension and retirement-income deduction, and never taxes Social Security.
Michigan vs Ohio on the same salary
On a $75,000 salary, a single filer keeps about $58,405 a year in Michigan against roughly $60,246 in Ohio — a difference of $1,841, or $153 a month.
Effective combined rates are 22.1% in Michigan and 19.7% in Ohio. Set that gap against living costs: index 91 here versus 92 there, with property tax at 1.38% and 1.53% respectively.
