How do I dispute my assessed value if I think it is too high?

A property valuation (assessment) may be disputed via the Real Estate Abatement Process. The Abatement Application is available in January at the Assessors' Office in Town Hall or under Downloadable Forms and may be filed after the Town has mailed the Third Quarter tax bill on or about December 31. The application for abatement must be received by the Assessors' Office no later than the close of business on the last day of the abatement filing period, which is generally the first workday in February (February 1st). If submitted via USP, the envelope must be postmarked no later than that same February 1st/first workday date.

Once submitted, the Board of Assessors has 90 days from the date the application was received to act on the appeal. Each and every appeal will receive written notification of the Assessors' action.

Filing an abatement does not put your tax payment on hold. Tax payments need to be rendered in a timely manner in order to protect further appeal rights to the Massachusetts Appellate Tax Board.

If you are dissatisfied with the decision of the Board of Assessors regarding your abatement request, you may file an appeal to the Appellate Tax Board (ATB). This must be done within three months of the Assessors' decision.
