Assessing

Assessing

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 8 a.m. - 5 p.m., Monday through 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.


7-year Property Recollection Project

In the coming weeks, assessors will be performing inspections at properties across the City that have not been inspected or sold in the last seven years. These inspections may take place between 8 a.m. and 5 p.m., Monday through Friday. Representatives will carry a City of Boston photo ID and drive a City vehicle. Have questions or concerns? Please contact us at 617-635-4321.

Community Preservation Act (CPA) Surcharge

In November 2016, Boston voters approved the Community Preservation Act (CPA) by voting “yes” on Ballot Question 5. By adopting the act, the City has created a Community Preservation Fund.

Community Preservation Act surcharge

The City finances the fund in part by a 1% property tax-based surcharge on residential and business property tax bills. You may see the surcharge on your property tax bills beginning with the Fiscal Year 2018 first-quarter tax bill in July 2017.
