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 life easier: starting with the 2026 tax year (the returns you file in early 2027), the State of Michigan will take over processing Flint’s income tax, so you’ll be able to file your city and state returns together — the same setup Detroit already uses. Until then, you file the city return separately with Flint’s income tax office. The rate itself isn’t changing.
