Michigan Payroll Taxes and Withholding Guide (2026)

What Makes Michigan Payroll Different

Federal payroll tax is the same in every state. What changes from one state to the next is the second layer: state income tax withholding, employer unemployment taxes, and any local wage taxes. Michigan sits in the middle of the complexity range. Its state income tax is refreshingly simple, a single flat rate with no brackets and no standard deduction, but its city income taxes make many Michigan pay stubs more complicated than those in a no-local-tax state.

Michigan's state tax is a flat 4.25% applied after a $5,900 personal exemption per person (2026), with no standard deduction layered on top. What sets Michigan apart from other flat-tax states like Pennsylvania or Illinois is the city layer: roughly two dozen Michigan cities, from Detroit down to smaller cities like Muskegon, levy their own income tax on wages. A worker in Detroit pays the flat state tax plus a 2.4% city tax, while a worker fifteen miles away in a non-taxing suburb pays only the state tax. The federal baseline behind all of this is explained in the how payroll taxes work guide.

Employee Withholding Overview in Michigan

A Michigan employee sees federal taxes, a flat state tax, and, in a taxing city, a municipal tax. There is no employee unemployment line and no state disability line. The deductions fall into three groups: federal taxes, Michigan state income tax, and an optional city income tax.

The federal lines work identically to any other state. For Social Security, the 2026 wage base is $184,500, after which Social Security stops for the year. Medicare has no cap. What is unique to Michigan is the combination: a simple flat state line, plus a city line that depends entirely on where you work or live, and no employee unemployment contribution at all.

How Is Michigan State Income Tax Withheld?

Michigan individual income tax is a flat 4.25%, and that same rate is the withholding rate. Unlike Georgia or North Carolina, Michigan applies no standard deduction; the only reduction is $5,900 per personal or dependency exemption for 2026. Employers follow the method in the Michigan Income Tax Withholding Guide (Form 446): subtract the prorated exemption amount for each exemption claimed on Form MI-W4, then apply 4.25% to the remainder.

Because the rate is flat, there are no brackets to walk. The federal Form W-4 sets federal withholding, covered in the W-4 withholding explained guide, while Form MI-W4 sets the Michigan exemption count. The statutory rate is 4.25%; a 2015 law ties a temporary reduction to strong revenue growth and lowered the rate to 4.05% for the 2023 tax year only, but it returned to 4.25% for 2024 and has held there through 2026.

Michigan Withholding Exemptions (Form MI-W4)

Form MI-W4 is Michigan's version of the federal W-4, and it is the lever a Michigan employee has over state withholding. It sets the exemption count that feeds the withholding formula.

Personal and Dependency Exemptions

Each exemption you claim on Form MI-W4 removes $5,900 from your annual Michigan taxable wages for 2026. You generally claim one exemption for yourself, one for a spouse who is not claimed elsewhere, and one for each dependent. Claiming more exemptions lowers the Michigan tax withheld each pay period; claiming fewer raises it. If you do not file a Form MI-W4 at all, the employer withholds with zero exemptions, which produces the highest withholding.

Reciprocity Exemption

A resident of Illinois, Indiana, Kentucky, Minnesota, Ohio, or Wisconsin who works in Michigan uses Form MI-W4 to claim exemption from Michigan withholding under reciprocity, so the employer withholds for the home state instead. That exemption applies to the state income tax only; a Michigan city tax can still apply to a nonresident who works in a taxing city.

To see how a given exemption count and optional city rate change take-home pay, use the Michigan paycheck calculator, which asks for MI-W4 exemptions and a city rate directly.

Michigan City (Municipal) Income Taxes

This is the layer that makes Michigan payroll more involved than a flat-tax state like Pennsylvania or Illinois. Under the Uniform City Income Tax Act, about two dozen Michigan cities levy their own income tax on wages, charging residents roughly double the nonresident rate. If you work or live in one of these cities, the city tax appears on your pay stub in addition to the flat state tax.

A nonresident who works in a taxing city generally owes the nonresident rate on wages earned in that city, while a resident owes the resident rate on all wages. A worker who lives in one taxing city and works in another may owe both, usually with a credit from the home city for tax paid to the work city. Detroit withholding is administered by the Michigan Department of Treasury; other cities administer their own. Because these rules vary by city, the Michigan paycheck calculator takes a single city rate you enter and applies it to your Medicare wages as a close estimate.

Employer Payroll Obligations in Michigan

Michigan employers carry the federal employer taxes plus State Unemployment Insurance through the Unemployment Insurance Agency (UIA). The federal side, covered in the employer payroll tax obligations guide, includes the matching 6.2% Social Security and 1.45% Medicare plus Federal Unemployment Tax (FUTA). On top of that, Michigan adds the employer UIA contribution. There is no employee unemployment contribution to withhold.

The Michigan UIA taxable wage base is $9,000 per employee for contributing employers, so the employer UIA tax stops once an employee's year-to-date wages pass $9,000. A new employer pays the standard 2.7% entry rate (5% for construction) until enough filing history exists for the UIA to assign an experience-based rate. These are employer costs and are never deducted from employee pay. The combined cost-to-hire can be modeled with the employer payroll tax calculator.

Michigan Has No Employee Unemployment Deduction

A handful of states, including Pennsylvania, take a small unemployment contribution directly from employee wages. Michigan is not one of them. The entire cost of Michigan unemployment insurance falls on employers through the UIA, so there is no employee unemployment line on a Michigan pay stub at all.

This matters most for workers who move to Michigan from a state that does deduct employee unemployment and expect to see the same line. In Michigan that line simply does not exist, and its absence is correct, not a payroll error. Michigan also has no state-run disability insurance or paid-family-leave payroll tax deducted from wages, unlike California or New York, so the mandatory deductions on a Michigan stub are federal taxes, the flat state income tax, and, in a taxing city, a city income tax.

Michigan Supplemental Wage Withholding

Supplemental wages are payments outside regular salary: bonuses, commissions, overtime, sales awards, and back pay. Many states apply a special flat supplemental rate to these payments. Michigan uses its ordinary flat withholding rate.

• Michigan state income tax on supplemental wages: the same flat 4.25% rate that applies to regular wages.
• City income tax: the same city rate applies to supplemental wages earned in a taxing city.
• Employee unemployment: none, on supplemental wages or regular wages.

Because the state rate is already flat, there is no separate Michigan supplemental schedule to look up. Federal income tax withholding on supplemental wages is a separate calculation set by the IRS, and Social Security and Medicare still apply under their own rules. For the federal supplemental math, use the Bonus Tax Calculator.

Michigan Filing and Payment Frequency

Michigan employers report and remit withheld state income tax through Michigan Treasury Online (MTO). Withholding is deposited on a monthly, quarterly, or accelerated schedule depending on the amount withheld, using Form 5080 for periodic sales, use, and withholding returns and reconciling annually on Form 5081 with the W-2 information. The federal deposit schedule is covered separately in the payroll tax deadlines guide.

Unemployment tax is reported and paid separately from income tax withholding, on a quarterly basis through the UIA using the Michigan Web Account Manager (MiWAM). City income tax withholding is filed separately with each taxing city or, for Detroit, through Michigan Treasury Online. New employees must be reported to the Michigan new hire directory within 20 days of the hire date.

How Take-Home Pay Works in Michigan

The calculation sequence runs from gross pay down to net pay. Because Michigan income tax begins with federal adjusted gross income, the same pre-tax deductions that reduce federal wages also reduce Michigan state wages, which keeps the two bases aligned before the $5,900 exemption is applied.

1. Start with gross wages for the pay period.
2. Subtract federal pre-tax deductions (401(k), Section 125 health premiums) to find taxable wages for both federal and Michigan state income tax.
3. Apply federal income tax withholding using the Form W-4 and IRS Publication 15-T.
4. Subtract the per-period share of $5,900 per MI-W4 exemption, then apply the flat 4.25% Michigan rate to the remainder.
5. If you work or live in a taxing city, apply the city rate to your city wages.
6. Subtract Social Security (6.2%) and Medicare (1.45%) on FICA wages (gross less Section 125 medical). The remainder is net pay; there is no employee unemployment line.

To see exact figures for a specific salary, exemption count, city rate, and pay frequency, use the Michigan paycheck calculator or the general take-home pay calculator for a full pre-tax benefits stack.

What Michigan Employees Should Check on a Pay Stub

• MI state tax line: Confirm Michigan income tax is withheld at 4.25% on wages after $5,900 per exemption. With zero exemptions the line is exactly 4.25% of Michigan wages. If your stub shows 4.05%, it is on an out-of-date 2023 rate.
• City tax line: If you work or live in Detroit, Grand Rapids, Lansing, or another taxing city, confirm the city line is present at the right resident or nonresident rate. If it is missing, you may owe a balance at filing.
• Exemption count: Verify the MI-W4 exemption number the employer keyed matches your current Form MI-W4, since each exemption is worth $5,900 off Michigan taxable wages.
• No employee unemployment line: Michigan does not deduct employee unemployment, so there should be no such line.
• FICA: Confirm Social Security at 6.2% (until $184,500 of wages for 2026) and Medicare at 1.45% with no cap.

What Michigan Employers Should Verify Before Running Payroll

• State registration: Confirm active accounts for Michigan withholding (Treasury, via MTO) and unemployment (UIA, via MiWAM), and check the annual UIA rate determination.
• MI-W4 on file: Collect a current Form MI-W4 from each employee; without one, withhold with zero exemptions.
• Current rate: Confirm the 4.25% rate and the $5,900 exemption for 2026 are set in the payroll system; a stale 4.05% rate under-withholds.
• City tax setup: Determine whether any work city or employee home city levies an income tax, and configure the correct resident and nonresident rates and any Detroit MTO filing.
• UIA settings: Confirm the $9,000 wage base and the assigned employer contribution rate are set in the payroll system.
• New hire reporting: Report each new worker to the Michigan new hire directory within 20 days.
