Our mission is to accurately assess property and provide prompt and courteous help to the public. We determine the value of property in Boston for the purpose of taxation.

Annual Property Maintenance Project

In the coming weeks, assessors from our department will be performing inspections at properties across the City from 9 a.m. - 5 p.m., Monday to Saturday. This is part of our annual Maintenance Project. Representatives will carry a photo ID badge by which you can verify their status as an Assessing Department employee. They will also drive a City of Boston vehicle. If you have any questions or concerns about an inspection, please contact the Assessing Department at 617-635-4321.


You can search FY2017 real estate assessments and taxes online through our online Assessing tool.
