An assessment is the value placed on property appearing in the Grand List—the list of all taxable and tax-exempt property in the town. To determine the tax liability for a particular property, the property assessment is multiplied by the town’s mill rate. In Connecticut, an assessment is equal to 70 percent of the fair market value as established by the municipal assessor. For motor vehicles and business personal property, this assessment is recalculated annually as of October 1st. Real estate assessments are established during the town-wide revaluations, which are performed on a schedule established by state law.
