Property owners can file an abatement application if they believe their property is:

  • overvalued
  • disproportionately assessed
  • improperly classified, or
  • eligible for a statutory exemption.

Applications may be filed after we issue third-quarter bills in late December 2019. The Fiscal Year 2020 abatement application filing deadline is February 3, 2020.

Abatement applications are available online starting January 1, 2020. Just visit the Assessing Online link below. Follow the instructions on Assessing Online to get the online abatement application for your property. Learn more about how to get an abatement application, either in-person or by mail.


Assessors will be performing inspections at properties across the City that have not been inspected or sold in the last seven years.

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.

The City has a number of tax relief programs for those homeowners who occupy the property as their principal residence. This year, the residential exemption will save taxpayers up to $2,879.79 on their tax bill. Personal exemptions may provide additional tax relief to those qualifying homeowners who are:

  • elderly
  • surviving spouses or minor children of deceased parents
  • 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, 2020. Just visit the link for Assessing Online below. Follow the instructions on Assessing Online to get the residential exemption and personal exemption applications for your property.


The Fiscal Year 2020 filing deadline for the residential exemption, personal exemption, and tax deferral is April 1, 2020.

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.
