Flint has a city income tax (and it's moving to state processing)

If you’re going to live or work in the city of Flint, budget for a city income tax on top of your state and federal ones. Flint is one of about two dozen Michigan cities with a local income tax: if you live in the city, you pay 1% of your income; if you live elsewhere but work in Flint, you pay 0.5% on what you earn there. Retirement income like Social Security and pensions isn’t taxed, and there’s a small per-person exemption. Returns are due April 30. One change is coming that should make filing easier: starting January 1, 2027, Michigan Treasury will process Flint’s 2026 and later city returns. Tax software will be able to transmit the state and Flint returns during the same filing session, much as it does for Detroit, but the Flint return will still be a separate city form. Until that transition, file with Flint’s Income Tax Division. The rates are not changing.
