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.
Latest updates:
It’s January and you should have received your third quarter tax bill by now.
Aside from telling you how much you owe, your bill has information about your property value and shows whether you are getting a residential exemption.
- If you have questions about your property value, or want to know more about filing an abatement application to contest your value, call our Valuation Hotline at 617-635-4288.
- The deadline for filing an abatement application this year is Monday, February 3, 2025.
- If you have questions about the Residential Exemption or want to know about our exemptions for the blind, disabled veterans, or seniors, please reach out to our Taxpayer Referral and Assistance Center at 617-635-4287, or email our staff at TRACFAXSG@boston.gov.
Both phone lines listed above are available Monday – Friday from 9:00 a.m. to 5:00 p.m. (except for Monday January 20 as City Hall is closed in observation of MLK day).
Our page has a lot of information about property values and exemptions for you to explore in the links below.

Personal Property Tax
Movable, physical property is subject to the personal property tax, but there are exceptions. Learn more about personal property tax.
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.
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.
Taxpayer Referral and Assistance Center
"TRAC" offers a "one-stop" service at City Hall for Boston taxpayers on tax-related matters.
