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.
You can search preliminary FY 2024 real estate assessments and taxes online through our online Assessing tool:
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.
Taxpayer Referral and Assistance Center
"TRAC" offers a "one-stop" service at City Hall for Boston taxpayers on tax-related matters.
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 Friday. 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.
10-Year Property Maintenance Project
Assessors will be performing inspections at properties across the City that have not been inspected or sold in the last 10 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.
