This PDF file (click image or this text to download) has the latest property tax millage rates for all cities and townships in Michigan. They're grouped by County, and within counties they're listed alphabetically with townships first, then cities.
A few cities have additional taxes for special overlay tax districts for public safety departments like police or fire, or other purposes. For these, the column on the far right will include those additional mandatory taxes.
Previous years' rates are available here.
A smaller file with just Oakland, Macomb and Wayne county property tax rates can be downloaded here.
