The Assessors' Office is responsible for determining the full and fair market value of all properties in Chatham as of January 1st every year per Massachusetts General Law. We maintain a complete database of all properties, their owners, and their assessments. In addition to the Real Property Valuations, the Assessing department determines the values for Personal Property accounts, as well as processing the Motor Vehicle Excise and maintaining the Boat Excise Billing Tax file. Our Office accepts and processes abatement requests for Motor Vehicle, Boat Excise, Real Property, Personal Property taxes as well as applications for statutory exemptions and real estate tax deferrals.
