HOW MASSACHUSETTS APPEALS WORK
THE SHORT VERSION

Massachusetts assesses at the city or town level, not the county, at full and fair cash value each year. You file an abatement with your local board of assessors, usually by February 1, then can appeal to the state Appellate Tax Board. An appeal helps when sales show your value is above market.

WHEN AN APPEAL MAKES SENSE
  • Recent comparable sales show your assessment is above what your home would sell for.
  • The record has an error in your home’s size, condition, or features, or the value is disproportionate to similar homes.
  • You file with your city or town board of assessors by the first installment due date, usually February 1.
WHEN IT USUALLY WILL NOT
  • Your bill went up but your assessed value is fair. A higher bill often comes from the tax rate, not the assessment.
  • You have no market evidence. The abatement reviews your home’s value, not the size of your bill.

Read the full explanation

In Massachusetts, your city or town, not the county, assesses your home every year at full and fair cash value. If you think your value is too high, you file an abatement application with your local board of assessors. In most communities the deadline is February 1, the due date for the first installment of the actual tax bill, or the next business day if that date is a weekend. If the board denies you, you can appeal to the state Appellate Tax Board. An appeal helps when recent sales show your assessment is above what your home would sell for, or the record has an error. It usually will not help just because your tax bill went up. This is general information, not tax advice.
