A mill rate determines the amount of property tax each homeowner is responsible for paying. This tax amount is expressed as one dollar for every $1,000 of assessed property value; mill or per mill means per thousand. Property taxes are often expressed this way by municipalities, so it can be useful to understand how the mill rate is calculated.
