About The City Assessor's Office

The Assessing Department is responsible for accurately determining the value of all real and personal property located within the City of Attleboro for the purpose of taxation. Assessors are obliged to assess all property at its full and fair market value as of January 1 of each year. The department is responsible for the administration of all property tax data records and maintains accurate parcel ownership data based upon recorded property transactions at the Registry of Deeds. It also administers the tax billing for the motor vehicle excise and boat excise tax.


The function of this office can be best defined by the oath an Assessor takes as defined by the Massachusetts General Laws, Chapter41, Section 29:


"I, having been chosen to assess taxes and estimate the value of property for the purpose of taxation for the City of Attleboro, do swear that I will truly and impartially, according to my best skill and true judgment, assess and apportion all such taxes as I may during that time assess; that I will neither overvalue nor undervalue any property subject to taxation, and that I will faithfully perform all duties of said office."
