We accurately determine the value of property in Boston for the purpose of taxation. Examples of property are cars, boats, and buildings.

Our mission is to accurately assess property and provide prompt and courteous help to the public. We collect all property tax data and maintain records of property ownership in Boston. We're also in charge of tax billing for motor vehicle excise and boat excise taxes.

Residential exemption increased for qualified homeowners

This year, the residential exemption will save qualified homeowners $2,433 on their tax bill, nearly $500 more than last year's amount. Additional tax relief for homeowners may be available by filing for a personal exemption. Qualified senior homeowners may also apply for the tax deferral program.

Applications for the residential exemption and most personal exemptions are available online starting January 1, 2017. You can find the applications through Assessing Online. You have until April 3 to file an application for the current fiscal year.
