A fresh statewide look at 2025 millage rates lays bare just how uneven property taxes are across Michigan. Several small cities in and around Detroit, especially Ecorse, Harper Woods and River Rouge, land near the top of the charts for homestead millage, while a scattering of rural townships in Livingston, Leelanau and Mason counties posted some of the lowest levies. For homeowners the bottom line is simple: both the local millage and your property’s taxable value play starring roles in what you actually pay every year.
The top and bottom: numbers to know
State tax records show Ecorse with one of the highest homestead totals, roughly 94.09 mills, while parts of Harper Woods ranged about 86.63–87.93 mills depending on school district and River Rouge measured around 81.69 mills. At the other end of the scale, certain township–school district combinations logged homestead rates in the mid teens, including Deerfield Township (Livingston County) at about 14.77 mills, Centerville Township (Leelanau County) at about 16.80 mills, and portions of Genoa and Logan townships near 16.36–16.85 mills. These municipal millage figures come from the Michigan Department of Treasury's 2025 total rates report (Michigan Department of Treasury).
How mills translate to a tax bill
One mill equals $1 of tax for every $1,000 of taxable value, so the raw millage number only becomes meaningful after you run that conversion, according to the Michigan Townships Association (Michigan Townships Association). The statewide average in the dataset used for the map was about 31.79 mills, meaning a home with $125,000 in taxable value would face roughly $3,973.75 in property taxes at that rate, a calculation reported in the interactive analysis by MLive. The basic formula is taxable value divided by 1,000, then multiplied by the millage rate, which is the quickest way to convert a mill rate into dollars owed.
Why higher rates don’t always mean a bigger bill
High millage often appears where property values are comparatively low, which can keep actual tax bills smaller than the headline rate suggests. The U.S. Census Bureau lists Ecorse’s median owner-occupied home value near $65,400 and Harper Woods’ median around $157,200 (U.S. Census Bureau; U.S. Census Bureau), while Census Reporter shows River Rouge with a median roughly $65,100 (Census Reporter), so two towns with similar millages can produce very different bills when market values diverge. Local voted levies, school district boundaries and whether a property’s taxable value is capped or uncapped after a sale also change the final amount homeowners pay.
Where to check and what might change
The Treasury report covers millages billed in 2025 and notes that tentative rates for 2026 will be posted in spring 2027, so numbers can move with new local votes or reallocated levies. Homeowners who want an estimate can use the Michigan Department of Treasury’s property tax estimator or contact their local assessor to confirm which county, city, school and special district levies apply to a parcel (Michigan Department of Treasury).
MLive’s interactive map and the Treasury’s rate table give residents the raw numbers; the key step is running the arithmetic on your own taxable value and checking whether school or debt levies apply in your district. If your town shows up near the top or bottom of the list, a quick call to the assessor’s office will clarify whether that millage is headed for your bill next season.
