The property tax rate is determined by dividing the total budget of the Town by the Net Taxable Grand List that is produced by the Town Assessor. The Net Taxable Grand List is a listing of all of the taxable Real Estate, Motor Vehicles, and Personal Property in the Town as of the assessment date of October 1. A tax rate of one mill produces $1 of taxes on each $1,000 of property assessment.
The voters of the Town of Plainville have the ultimate choice as to what the mill rate will be by their participation in the budget meetings in April and the annual budget referendum in May. Once the budget has been approved, the Town Council simply does the math and sets the rate.
