Michigan 4.25% Flat Tax and $5,400 Personal Exemption: Why a Single Detroit Worker Earning $70,000 Owes $2,746 in State Tax While a Texas Worker Owes Nothing
Michigan's flat 4.25% state income tax applies to all earned income after deducting personal exemptions. Unlike a graduated system where higher income triggers higher rates, every Michigan worker above the exemption threshold pays exactly 4.25% on their taxable income. The only variable is how many exemptions you claim, each worth $5,400 off your taxable base.
A single filer earning $70,000 with one exemption owes 4.25% on $64,600, exactly $2,746. That same gross in Texas or Florida generates zero state income tax. The table below shows how the exemption count changes your effective Michigan state tax rate:
MI State Tax = (Gross Annual − Exemptions × $5,400) × 4.25%
Michigan City Income Taxes: Why Detroit Residents Pay 2.4% More on Every Dollar of Income Than Workers in Surrounding Suburbs
Michigan is one of a small number of states that allows cities to levy their own income taxes. Twenty-two Michigan cities use this authority, with Detroit as the most significant, charging 2.4% on resident income and 1.2% on non-residents who work within city limits. On a $70,000 salary, that is an additional $1,680 per year in city tax alone, on top of the 4.25% state rate.
The distinction between resident and non-resident rates matters: if you live in Detroit, you owe the full 2.4% on all income regardless of where you work. If you live in the suburbs but commute to a Detroit workplace, you owe only 1.2%, and your employer should withhold it automatically. Below are the six most common Michigan city tax jurisdictions:

City tax is not included in Michigan state withholding. Employers in taxing cities withhold it separately and remit it to the city. Verify your specific city's rate at your local city treasury or the Michigan Treasury's city income tax resources.
Five Michigan Paycheck Calculation Errors That Produce Wrong Take-Home Estimates
Forgetting city income tax for Detroit workers
Workers employed in Detroit often overlook the 1.2% non-resident rate if they live outside the city. Detroit employers withhold it automatically, but many workers are surprised when they see it on the first pay stub. Detroit residents owe the full 2.4% on all income, including income earned outside the city.
Using the wrong number of personal exemptions
Claiming zero exemptions withholds more Michigan tax than necessary; claiming too many results in a state tax bill in April. Use the exemption count that matches your actual W-4 or Michigan Schedule W filing. Each exemption saves you roughly $230 in annual Michigan state tax ($5,400 × 4.25%).
Confusing bi-weekly with semi-monthly pay frequency
Bi-weekly (26 pay periods/year) and semi-monthly (24 pay periods/year) look similar but produce different results. A $3,000 gross bi-weekly yields $78,000 annual income; the same gross semi-monthly yields $72,000. Selecting the wrong frequency will skew every line of your estimate.
Using an outdated Social Security wage base
The SS wage base increased to $176,100 for 2025 from $168,600 in 2024. High earners who stop paying Social Security mid-year will see their net pay increase at that point. Using the old figure will underestimate SS withholding by up to $460 annually.
Omitting city tax from total burden
This calculator includes city tax for Detroit, Grand Rapids, Flint, Lansing, and Saginaw when you select a city. If you leave the city selector at 'None' but work in a taxing city, your take-home estimate will be overstated by 1%–2.4% of gross pay depending on your city and residency status.

Pro Tip
If you live in Detroit but commute to work outside the city, you still owe the Detroit resident rate (2.4%) on all your income via a resident return. Your suburban employer will not withhold Detroit city tax automatically, budget for it or make quarterly estimated payments to Detroit.
