    Mill Rates for FY 2014-2026

    Metadata Updated: March 22, 2026

    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.

    The rates for each year are based on the grand list from two years prior. For example, the mill rates for the 2021 fiscal year are based off the 2019 grand list.

    Starting in FY 2017, legislation allows municipalities and special taxing districts to tax motor vehicles at a different rate than other taxable property, but it imposes a cap on the mill rate for motor vehicles. No district or borough may set a motor vehicle mill rate that if combined with the motor vehicle mill rate of the town, city, consolidated town and city or consolidated town and borough in which such district or borough is located would result in a combined motor vehicle mill rate above the cap.
