Created by legislation in 1909, County Boards of Taxation serve as the supervising taxing authority for their respective counties.  The office of the Board of Taxation falls into two major categories:  Administrative and Appellate. Through legislation enacted in 1973, all 21 County Boards of Taxation operate under a uniform set of rules first promulgated by the Division of Taxation entitled, Rules for County Boards of Taxation, which help to ensure uniform operation of the boards.  The County Tax Administrator is responsible for the administrative/statutory day–to-day office functions.
 
The Board of Taxation’s primary responsibility is the certification of property tax assessments.   Other functions of the Board of Taxation are the equalization of assessments for the purpose of county taxes, the preparation of the abstract of ratables, the supervision of municipal tax assessors, the certification of municipal tax rates and other various (mandated) tasks and reports, and the development of inter-municipal equalization of assessments.  The Board of Taxation also conducts hearings of real property tax assessment appeals filed by the taxpayer and renders judgments.
 
Our goal is to serve the twenty-five municipalities within Middlesex County efficiently, respectfully, and professionally within our jurisdiction. We invite you to browse our website and search our real property tax related links for information.​
