How Are Property Taxes Calculated?

Property taxes are calculated as shown below:
Number of certified Acres X Per Acre Valuation* = Current Use Valuation
Current Use Valuation X Town's Per Thousand Tax Rate = Estimated tax bill under current use

*Note: The per acre valuation will be based on your land’s productivity, as determined by the local assessor. This calculator will generate a High (H), Medium (M), and Low (L) productivity valuation.
