Abatement Information

An abatement is a reduction of the assessed value caused by an error. A taxpayer must apply for an abatement each year there is a dispute.

Abatement applications can only be filed once a year between the mailing of the third quarter tax bill and due date usually February 1. Abatement applications cannot be accepted at any other time or for any previous years. For this reason, we strongly encourage all taxpayers to review their assessed value each year during the months of December or January.

Reasons for Abatement
  • Overvaluation - The assessed value is greater than fair market value.
  • Disproportionate Assessment - The assessed value of a class of property is assessed at a different percentage than the entire town or a single property is assessed differently than like properties. Disproportionate assessments are extremely rare since all assessments are based on computer models.
  • Improper Classification - Example: a residential building site is assessed as commercial.
  • Exemption - The property meets the requirements to be exempt based on use.
Abatement Procedures
Abatement applications must be received at the Assessors Office prior to 12:30 P.M. on February 1st.  Applications that are mailed must contain a US Post Office postmark on or before February 1st. Massachusetts statutes prevent Assessors from granting an abatement unless the application is filed timely.

Information Request
The Board may ask for additional information from the taxpayer, or may ask to inspect the property. This information will allow the Board to determine the fair market value of the property. You must provide all the information requested and allow the inspection within thirty days. Failure to provide the  information or allow the inspection will cause your application to be denied and will bar any appeal.

Action by the Board of Assessors
The Assessors have 3 months to act on your application. If the Board fails to act, or chooses not to act, your application is deemed denied by law. The Assessors will send a notice after acting on your application. The notice will be either a denial notice or an abatement certificate. If an abatement is granted, your account is credited. Please refer to the abatement certificate for specific amounts and credits. If your abatement is denied, you will receive a denial notice.
