Mill Rates A mill is equal to $1.00 of tax for each $1,000 of assessment. To calculate the property tax, multiply the assessment of the property by the mill rate and divide by 1,000. For example, a property with an assessed value of $50,000 located in a municipality with a mill rate of 20 mills would have a property tax bill of $1,000 per year.
