Michigan Payroll Taxes Guide →Short Answer
This Michigan paycheck calculator estimates net take-home pay after federal income tax withholding, Social Security (6.2%), Medicare (1.45%), Michigan income tax withheld at a flat 4.25% for 2025 after $5,800 per MI-W4 exemption with no standard deduction, and an optional Michigan city income tax. For a single filer earning $65,000 per year paid biweekly and claiming one exemption, gross pay is $2,500.00 per period, the Michigan state line is $96.77, and net take-home outside a city-tax city is approximately $1,984.52. If that worker lives or works in Detroit, the 2.4% city tax adds about $60.00 per period, lowering net to roughly $1,924.52. Michigan has no employee unemployment contribution, but about two dozen Michigan cities levy a local income tax on top of the flat state rate.
Key Takeaways
- Michigan withholds a flat 4.25% state income tax for 2025. Unlike Georgia or North Carolina, there is no standard deduction inside the formula, so with zero exemptions the effective state rate is exactly 4.25%.
- The only reduction is the personal exemption: $5,800 for each exemption claimed on Form MI-W4 (2025). It was $5,600 for 2024 and rises to $5,900 for 2026.
- The rate was 4.25% for 2024, 2025, and 2026. It dipped to 4.05% only for the 2023 tax year because of a one-year revenue trigger, which is a common source of confusion.
- About two dozen Michigan cities levy a local income tax. Detroit is 2.4% resident / 1.2% nonresident; Grand Rapids and Saginaw are 1.5% / 0.75%; most others are 1% / 0.5%. Enter your city rate and the calculator adds the line.
- A traditional 401(k) deferral reduces Michigan state tax. Michigan income tax starts from federal adjusted gross income, so a deferral already excluded from federal wages is excluded from Michigan wages too. A $7,800 deferral saves about $332 of Michigan state withholding.
- Section 125 cafeteria-plan medical premiums reduce federal wages, Michigan wages, and Social Security and Medicare wages.
- Michigan has no employee-paid unemployment tax and no state disability deduction. Unemployment insurance is funded entirely by employers through the UIA.
- Bonuses and supplemental wages follow separate federal withholding rules (flat 22% or aggregate method) and the same flat Michigan rate. For supplemental pay use the Bonus Tax Calculator and see the Bonus Tax Withholding Guide.

How This Calculator Works
Hourly Mode: Gross Pay Per Period
Gross pay per period equals the hourly rate multiplied by hours worked per week, then scaled to the pay period. For biweekly pay: hourly rate × hours per week × 2. For weekly: hourly rate × hours per week. For semi-monthly and monthly: hourly rate × hours per week × (52 ÷ periods per year).
Salary Mode: Gross Pay Per Period
Gross pay per period equals annual salary divided by the number of pay periods per year. Weekly: ÷ 52. Biweekly: ÷ 26. Semi-monthly: ÷ 24. Monthly: ÷ 12.
Which Wages Michigan Taxes
Michigan income tax begins with your federal adjusted gross income, so the wages Michigan withholds on are the same wages that are subject to federal income tax withholding. That has a clean, practical result on a paycheck:
- Federal taxable wages = gross − Section 125 medical − 401(k) elective deferral.
- Michigan state taxable wages = the same base as federal, then reduced by $5,800 per exemption before the flat 4.25% rate is applied. There is no separate Michigan standard deduction.
- FICA and city wages (Social Security, Medicare, municipal) = gross − Section 125 medical. The 401(k) deferral does not reduce FICA, and this calculator applies the city rate to that same Medicare wage base.
Because Michigan starts from federal income, a traditional deferral lowers the state line as well as the federal line, which is why the calculator shows a small Michigan state tax saving whenever you enter a 401(k) amount. Michigan cities set their own taxable-wage rules, so treat the city line as a rate-based estimate and confirm your city's exact base.
Social Security Tax
Social Security is 6.2% of annualized FICA wages up to the $176,100 wage base for 2025. The per-period amount is the annualized Social Security tax divided by pay periods. This calculator does not track year-to-date cumulative wages, so for workers approaching the wage base, actual withholding will stop mid-year once the limit is reached.
Medicare Tax
Standard Medicare is 1.45% on all FICA wages. The calculator adds the 0.9% Additional Medicare Tax on annualized FICA wages above $200,000, matching the employer withholding rule in IRS Topic 560: withholding starts once wages exceed $200,000 in a calendar year regardless of filing status. Final liability on Form 8959 uses filing-status thresholds ($200,000 single/HOH, $250,000 MFJ, $125,000 MFS).
Federal Income Tax Withholding
The calculator follows IRS Publication 15-T Worksheet 1A (Percentage Method for Automated Payroll Systems) for 2025:
- Annualize the per-period gross pay (multiply by pay periods per year).
- Subtract annualized Section 125 medical premiums and 401(k) elective deferrals to get federal taxable wages.
- Add Step 4a other income; subtract Step 4b additional deductions.
- Subtract the line 1g allowance: $12,900 for married filing jointly or $8,600 otherwise. If the W-4 Step 2 box is checked, subtract $0 instead. The result is the Adjusted Annual Wage Amount.
- Apply the Annual Percentage Method table for the W-4 filing status - the STANDARD schedule, or the Step 2 Checkbox schedule when the Step 2 box is checked - then divide the tentative annual withholding by pay periods.
- Subtract Step 3 dependent credits divided by pay periods, then add Step 4c extra withholding.
Michigan Income Tax (Form 446 Flat Method)
Michigan follows the method in the Michigan Income Tax Withholding Guide (Form 446). The employer subtracts $5,800 for each personal and dependency exemption claimed on Form MI-W4, prorated to the pay period, and multiplies the remainder by the flat rate:
MI tax = 4.25% × ( annual wages − ($5,800 × exemptions) )
There is no separate Michigan standard deduction, so the exemptions are the only reduction. With zero exemptions the effective Michigan rate equals the flat 4.25% exactly; each exemption pulls the effective rate down. Michigan's statutory rate is 4.25%, and while a 2015 law ties a temporary reduction to state revenue growth (it cut the 2023 rate to 4.05%), the rate is back at 4.25% for 2024, 2025, and 2026. Any extra Michigan withholding you requested on Form MI-W4 is added on top.
Michigan City (Municipal) Income Tax
About two dozen Michigan cities impose a local income tax under the Uniform City Income Tax Act. Detroit is the highest at 2.4% for residents and 1.2% for nonresidents; Grand Rapids and Saginaw levy 1.5% and 0.75%; roughly twenty other cities levy 1.0% and 0.5%. This calculator applies the single rate you enter to your Medicare wages as a consistent baseline. Cities differ on exactly which wages are taxable and on the credit a resident gets for tax paid to a work city, so treat the city line as a close estimate and confirm the specifics with your city.
No Michigan Employee Unemployment Tax
Michigan collects no employee unemployment contribution; the entire cost of Michigan unemployment insurance falls on employers through the Unemployment Insurance Agency (UIA). Michigan also has no state disability insurance or paid-family-leave payroll deduction. That leaves a Michigan paycheck with federal taxes, the flat 4.25% state tax, and, in a taxing city, a municipal tax, plus FICA.
Real-World Paycheck Scenarios
Scenario 1: Salaried Single Filer in Detroit
Devin earns $65,000 per year at a Detroit firm, paid biweekly, filing single with a standard federal W-4 and claiming one exemption on Form MI-W4. As a Detroit resident he owes the 2.4% city income tax. He has no 401(k) deferral and no cafeteria-plan premiums. His biweekly gross is $65,000 ÷ 26 = $2,500.00.
Michigan detail: Devin's annual wages of $65,000 are reduced by one $5,800 exemption to $59,200, times 4.25% = $2,516.00 annual, divided by 26 = $96.77 per period. His effective Michigan state rate is about 3.87% of gross, below the 4.25% flat rate only because of the single exemption. City detail: Detroit taxes his Medicare wages, which here equal the full $2,500.00, at 2.4% = $60.00. Outside a city-tax city his net would be about $1,984.52; the Detroit line costs him roughly $1,560 a year.
Scenario 2: The 401(k) Deferral That Cuts State Tax but Not City Tax
Renee earns $85,000 per year in Detroit, paid biweekly, filing single with one MI-W4 exemption, and owes the 2.4% city tax. She defers $300 per period to a traditional 401(k) ($7,800 per year). The deferral lowers her federal and Michigan state wages to $77,200, but her Medicare wages, and therefore her city wages, stay at $85,000.
Renee's federal and Michigan wages are both $77,200 (gross less the $7,800 deferral), while her FICA and city wages stay at $85,000 because a 401(k) deferral never reduces Social Security and Medicare, and this calculator rides the city tax on that Medicare base. Her Michigan state tax of $116.71 comes from ($77,200 − $5,800) × 4.25% ÷ 26. If she stopped the deferral, her Michigan state tax would rise to $129.46, so the deferral saves $7,800 × 4.25% = $331.50 per year of Michigan state withholding, but her $78.46 Detroit line does not change. See the Pension and Annuity Income Tax Guide for how distributions are treated at the back end.
Practitioner Insight
The Michigan detail that surprises people is the city tax, not the state tax. The flat 4.25% state line is simple and rarely questioned. What catches workers is that a job in Detroit, Grand Rapids, Lansing, or one of the other taxing cities adds a second income tax line, and it is levied on the full Medicare wage with no exemption of its own. Someone who took a Detroit job for the higher salary sometimes forgets that 2.4% comes off the top on the city side, on top of the state and federal tax.
The second recurring item is the 4.05% versus 4.25% confusion. A client will pull up an old 2023 return or an article from that year, see 4.05%, and insist the payroll department overwithheld. The 4.05% was a one-year event driven by a revenue trigger; 2024, 2025, and 2026 are all back at 4.25%. We keep a note on this because it comes up every filing season.
Third is the 401(k) split. Retirement savers assume a deferral cuts every tax line the way it cuts federal and Michigan state tax. It does lower the state line, because Michigan starts from federal income, but the city line rides on Medicare wages and does not move. We show clients the two bases side by side so they budget correctly: the deferral is still worth it, but the city keeps taxing the full wage.
When This Calculator Gives a Less Accurate Estimate
- City-specific wage rules: The calculator applies one city rate to your Medicare wages. Michigan cities differ on exactly which wages are taxable, on the treatment of pre-tax deferrals, and on the credit a resident gets for tax paid to a work city. If you live in one taxing city and work in another, your true withholding involves the work-city tax plus any home-city tax net of a credit. Enter your work-city rate for the closest single-rate estimate.
- Nonresident city rate: Detroit, Grand Rapids, and the others charge nonresidents about half the resident rate. Enter 1.2% instead of 2.4% for a Detroit nonresident, and the equivalent for your city, if you work in the city but live outside it.
- Very low earners with several exemptions: Once $5,800 times your exemptions exceeds annual wages, Michigan state withholding is zero. The calculator floors the state line at zero, which is correct, but the exact break-even depends on your specific exemption count.
- Roth 401(k) contributions: A Roth deferral is a post-tax deduction. It reduces neither federal nor Michigan taxable wages. Do not enter it in the 401(k) field, which models traditional pre-tax deferrals only.
- Reciprocity for border residents: Michigan has reciprocal agreements with Illinois, Indiana, Kentucky, Minnesota, Ohio, and Wisconsin, so a resident of one of those states working in Michigan generally files a Form MI-W4 exemption and pays their home state instead. This calculator assumes Michigan resident withholding.
- Year-to-date tracking and variable hours: The calculator annualizes a single consistent pay period. Social Security stops mid-year at the wage base, overtime and seasonal hours vary, and bonuses use supplemental federal withholding rules.
Frequently Asked Questions
What is the Michigan state income tax withholding rate for 2025?
Michigan withholds state income tax at a flat 4.25% for 2025. Employers apply 4.25% to wages after subtracting $5,800 for each personal and dependency exemption claimed on Form MI-W4. Michigan has no separate standard deduction inside the withholding formula, so with zero exemptions the effective state rate is exactly 4.25%. The rate has been 4.25% for 2024, 2025, and 2026; it dipped to 4.05% only for 2023 because of a one-year revenue trigger.
How much is the Michigan personal exemption for 2025 withholding?
The Michigan personal and dependency exemption is $5,800 for 2025 (it was $5,600 for 2024 and rises to $5,900 for 2026). Each exemption you claim on Form MI-W4 removes $5,800 of annual wages before the 4.25% rate is applied. Michigan does not layer a separate standard deduction on top; the exemptions are the only reduction in the withholding formula. If you do not file a Form MI-W4, the employer withholds with zero exemptions.
Do 401(k) contributions reduce Michigan state income tax?
Yes, for the Michigan state line. Michigan income tax starts from your federal adjusted gross income, and a traditional 401(k) or 403(b) elective deferral is already excluded from federal taxable wages, so it is excluded from Michigan taxable wages too. A worker deferring $7,800 to a traditional 401(k) reduces Michigan taxable wages by $7,800 and saves about $332 of Michigan state withholding at the 4.25% rate. The deferral does not reduce Social Security and Medicare wages. Michigan city income taxes generally follow their own base rules, so confirm your city's treatment of pre-tax deferrals separately.
Does Michigan have local city income taxes on wages?
Yes. About two dozen Michigan cities levy a local income tax on wages under the Uniform City Income Tax Act. Detroit is the highest at 2.4% for residents and 1.2% for nonresidents who work in the city. Grand Rapids and Saginaw levy 1.5% resident and 0.75% nonresident, and roughly twenty other cities levy 1.0% resident and 0.5% nonresident. If your work city or home city taxes wages, that city line appears on your pay stub in addition to the flat Michigan state tax. Enter your city rate in the calculator to add the line.
Do Michigan employees pay state unemployment tax?
No. Michigan unemployment insurance is funded entirely by employer contributions to the Unemployment Insurance Agency (UIA). Employees pay nothing toward Michigan unemployment, so there is no employee unemployment line on a Michigan paycheck. For 2025 employers pay on the first $9,000 of each worker's wages, at a new-employer rate of 2.7% (5% for construction) or an experience-rated rate. Michigan also has no state disability insurance or paid-family-leave payroll tax deducted from wages.
Was the Michigan income tax rate 4.05% or 4.25%?
Both, in different years. Michigan's statutory individual income tax rate is 4.25%. A 2015 law ties a temporary reduction to state revenue growth, and that trigger lowered the rate to 4.05% for the 2023 tax year only. For 2024, 2025, and 2026 the rate is back at 4.25%. If you are looking at a 2023 pay stub or return you may see 4.05%, but current Michigan withholding uses 4.25%.
How do I fill out Form MI-W4 for Michigan withholding?
Form MI-W4 is Michigan's employee withholding exemption certificate. You enter the number of personal and dependency exemptions you are entitled to claim, each worth $5,800 off your annual Michigan taxable wages in 2025. You can also request additional Michigan withholding per pay period. Claiming more exemptions lowers the Michigan tax withheld from each paycheck. If you do not file a Form MI-W4, or you work in a city with its own tax, the employer withholds with zero exemptions at the flat rate.
Does Michigan tax health insurance premiums paid through a cafeteria plan?
No. Employer-sponsored medical premiums paid through an IRC Section 125 cafeteria plan are excluded from federal taxable wages, and because Michigan income tax begins with federal adjusted gross income, they are excluded from Michigan taxable wages as well. Section 125 medical premiums also reduce Social Security and Medicare wages. Both a traditional 401(k) deferral and a Section 125 medical premium reduce the Michigan state taxable wage base.
What is the Social Security wage base for 2025?
The Social Security wage base for 2025 is $176,100. Social Security tax at 6.2% applies to wages up to this amount, and withholding stops once cumulative wages for the year exceed it. Medicare has no wage base limit and continues at 1.45% on all wages. Employers withhold an additional 0.9% Medicare surtax on wages above $200,000 regardless of filing status; final liability thresholds are $250,000 for married filing jointly and $125,000 for married filing separately.
How does a Michigan paycheck compare to other states?
At the same gross salary, a Michigan worker takes home less than a worker in Texas or Florida, which levy no state income tax, because Michigan adds the flat state line, and less again if they work in a taxing city like Detroit. Compared with a graduated high-tax state like California or New York, Michigan is simpler because the rate never rises with earnings. Michigan's 4.25% flat rate sits below Georgia's 5.19% and Illinois's 4.95% on the state line, but the city tax can close much of that gap in Detroit and Grand Rapids. Compare directly with the Ohio, Illinois, Georgia, North Carolina, and New York calculators.
Why does my actual Michigan paycheck differ from this estimate?
This calculator estimates standard federal withholding, FICA, the flat 4.25% Michigan state withholding after $5,800 exemptions, and an optional city tax at the rate you enter. Actual paychecks also reflect post-tax deductions such as Roth 401(k) contributions and garnishments, year-to-date cumulative Social Security tracking, city-specific rules on which wages are taxable and any home-city credit, employer-specific payroll adjustments, mid-year MI-W4 changes, and any additional Michigan withholding you requested. The calculator assumes consistent pay each period and does not track cumulative wages across the year.
What To Do Next
Start by confirming two Michigan-specific lines on your most recent pay stub. First, check the state line: it should equal about 4.25% of your wages after $5,800 for each MI-W4 exemption, with no standard deduction. If you claim zero exemptions, the state line is exactly 4.25% of your Michigan wages. Second, check whether a city tax line is present. If you work or live in Detroit, Grand Rapids, Lansing, or one of the other taxing cities, that line should be there, and if it is missing you may owe a balance at filing.
If your exemption count is wrong, the fix is a new Form MI-W4 submitted to your employer. If your pay stub still shows 4.05%, it is running on an out-of-date 2023 rate and should be corrected to 4.25%.
For the full Michigan employer picture, including the city taxes, the state unemployment wage base, and filing frequencies, read the Michigan Payroll Taxes guide. To understand how withholding connects to your year-end liability, see How Payroll Taxes Work and W-4 Withholding Explained. To decode every line on the stub itself, use How to Read a Pay Stub. If you also have self-employment income, the 1099 Tax Calculator estimates the federal side including self-employment tax.
