Overview

Commercial tax abatements reduce assessed property tax liability when the assessed value is higher than market value or when statutory credits apply. Abatements are decided by the City of Boston Assessing Department following state law and local procedures. The process is administrative and may require evidence such as appraisal reports, leases, or expense records.

Eligibility & Common Grounds

  • Incorrect assessment: evidence that the assessed value exceeds market value.
  • Clerical or factual errors on the tax record.
  • Completed or incomplete construction affecting valuation.
  • Eligibility for statutorily authorized credits or exemptions.
Gather independent valuation or appraisal documents before you apply.
