Assessors from our department will be performing inspections at properties across the City in July and August 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.
The City has a number of tax relief programs for those homeowners who occupy the property as their principal residence. Last year, the residential exemption saved taxpayers up to $3,153.02 on their tax bill. Personal exemptions may provide additional tax relief to those qualifying homeowners who are:
- surviving spouses or minor children of deceased parents, and
- veterans or certain members of the National Guard.
The tax deferral program for seniors is also available to qualifying senior homeowners whose rising expenses have made it difficult to continue owning their home.
The online applications for the residential exemption and most personal exemptions are available online starting January 1, 2022. Just click on the Assessing Online link below. Follow the instructions on Assessing Online to obtain the residential exemption and personal exemption applications for your property.
The Fiscal Year 2022 filing deadline for the residential exemption, personal exemption, and tax deferral is April 1, 2022.
Assessors will be performing inspections at properties across the City that have not been inspected or sold in the last ten 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.
Property owners can file an abatement application if they believe their property is:
- disproportionately assessed
- improperly classified, or
- eligible for a statutory exemption.
Applications may be filed after the third-quarter bills are issued in late December 2021. The Fiscal Year 2022 abatement application filing deadline is February 1, 2022.
Abatement applications are available online starting January 1, 2022, through Assessing Online. Follow the instructions on Assessing Online to obtain the online abatement application for your property. We have information online on how to get an abatement application either in-person or by mail.
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 beginning with the Fiscal Year 2018 first-quarter tax bill in July 2017.
Taxpayer Referral and Assistance Center
"TRAC" offers a "one-stop" service at City Hall for Boston taxpayers on tax-related matters.
The City has tax incentive programs to advance its economic development and housing goals. These programs include Chapter 121A, Chapter 121B, Tax Increment Financing, and Special Tax Assessment.
We created a page to give you more information about these programs. You can also download active tax agreements with the City.
Payment in Lieu of Tax (PILOT) Program
You must complete this form if you are filing an application for abatement on the basis of statutory exemption.
Each report presents in text, charts, and tables an overview of property taxes in the City of Boston. Through comparative and historical data, a taxpayer can compare Fiscal Year assessments and tax rates with those in earlier years and with those in other jurisdictions:
