Office of the Tax Assessor
Property AssessmentsThe Assessor works on behalf of Plainsboro Township under the direction of the New Jersey Division of Taxation and the Middlesex County Board of Taxation. The Assessor is charged annually with placing an assessed value on each property in Plainsboro. The assessment should reflect the properties full fair market value as of October 1st of the previous tax year, which is known as the valuation (or assessing) date. The values are determined after a careful analysis of property sales, cost data and income data.
The total value of all properties within the Township are then submitted to the Middlesex County Board of Taxation and are used to calculate a tax rate for each municipality within the County.
