Twenty-four cities tax income
Michigan allows cities to levy an income tax under the City Income Tax Act, and 24 do, including Detroit, Grand Rapids, Lansing, Flint, Saginaw and Pontiac. Under the uniform ordinance a resident rate is normally 1% and nonresidents who work in the city pay half the resident rate; a few cities, Detroit among them, kept higher rates. Because the rate depends on where you live and where you work, city taxes are not included in this calculator; subtract your city’s rate from the result.
Retirement income
Michigan is phasing in a larger exemption for pension and retirement income, which doesn’t affect your paycheck today but changes the value of saving through a 401(k).
Credits not modelled
The Michigan earned income tax credit (a percentage of the federal credit), the homestead property tax credit and the home heating credit can reduce what you owe or produce refunds. They depend on details beyond your pay.
