How the Michigan estimate works
Enter gross pay for one pay period, federal W-4 adjustments, and the state details shown above. Federal withholding follows Publication 15-T. Michigan reduces each paycheck by the pay-period value of the employee’s 2026 MI-W4 personal and dependency exemptions, then applies 4.25% and any requested additional amount. City withholding uses the official resident, nonresident, and exemption values for all 24 Michigan income-tax cities. When work and residence cities differ, the residence-city rate is reduced by the work city’s nonresident rate, with no negative remainder.
Example: The official 2026 Detroit guide shows that weekly wages of $200 with three city exemptions produce $3.97 of Detroit resident withholding. WageFrame follows the same per-paycheck exemption rounding before applying the city rate. The calculator does not assume any unentered benefit deduction or invent a tax result.
Weekly, biweekly, semimonthly, and monthly are the supported paycheck frequencies. “Annual salary” is an earnings input and the annual view is a simple period multiplication; neither is an annual payroll-period method. The special Form W-4 adjustment for nonresident aliens is not modeled.
Which Michigan city payroll taxes are included? WageFrame includes resident and nonresident withholding for all 24 Michigan cities that impose an income tax. Confirm both the predominant work city and residence city; an unresolved city status produces a partial estimate instead of assuming local withholding is zero.
