Millage rates are one of the most misunderstood parts of a property tax bill. The assessment determines the value side of the equation; the millage rate determines how that value turns into taxes.
What is a mill?
A mill is one dollar of tax for every $1,000 of taxable value. A local tax bill may include multiple millages for schools, county services, city or township operations, libraries, parks, debt, and special districts.
Why it matters in an appeal
Most assessment appeals do not directly challenge the millage rate. They challenge the assessed or taxable value. But understanding the millage rate helps you estimate what a lower valuation could mean in real dollars.
Simple example
If the taxable value is $300,000 and the combined millage rate is 40 mills, the annual tax is roughly $12,000. If an appeal reduces taxable value to $270,000, the same millage rate produces roughly $10,800.
