of Taxation each January. This Tax List also includes a directory for property identification, information concerning exempt properties, tax data and a schedule of all tax ratables within the Town.

Assessment Review

In order to have your assessment reviewed by the Tax Assessor, please supply the following data concerning your property.  Assessment reviews are only conducted from October 1st to December 20th, with any changes being made prior to the filing of the Tax Book by January 10th.  You will be notified of the results by mail via the annual postcard (usually mailed end of January) or you can contact the office after January 10th for the status.  If you are not satisfied with the outcome, you can pursue the appropriate venue for appeal by April 1st of the tax year in question (file with the County Tax Board if assessment is under $1,000.000 or State Tax Court for anything else).  No new information will be considered after December 1st.  A copy of your Property Record Card can be obtained to assist in our review, just contact the office.
