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.

Filing for a residential exemption, personal exemption, or tax deferral

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 $2,538 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, 2018 by clicking on Assessing Online below. Follow the instructions on Assessing Online to obtain the residential exemption and/or personal exemption application for your property.

The Fiscal Year 2018 filing deadline for the residential exemption, personal exemption, and tax deferral is April 2, 2018.

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.
