How to file for a real estate tax abatement

Last updated:

An abatement is a reduction in your property taxes. You have three options when submitting an application:

Step
1

Before you get started by mail

To file an abatement, you need to meet these requirements:

  • You can only submit an application after your third-quarter tax bill and no later than February 1.
  • You can only file an abatement for the current fiscal year. You can’t file an application for previous years.

The Assessing department has three months to review your application and respond.

Step
2

Complete your application

We make applications available through Assessing Online after we issue third-quarter tax bills.

When you search for your property through Assessing Online, click the "details" link. That will pull up information on your property, as well as an option to download an Abatement application:

You can also contact the Assessing Department at 617-635-4321. We will send you an Abatement application, along with an Information Requisition Form.

NOTE ON INFORMATION REQUISITION FORMS
  • If you don’t give us the information we ask for in the form within 30 days of filing your abatement application, we will deny your application.
  • If you don’t fill out the form, you may also lose your right to appeal to the Appellate Tax Board.
  • If you are filing an abatement application because you think you may qualify for a statutory exemption, you must submit a completed Statutory Exemption Information Requisition Form.
