Real Estate Tax

The Massachusetts Department of Revenue (DOR) mandates that every town fully update its property assessments each year to reflect the current fair market value. Wellesley's updated property assessments are submitted to the DOR each year for its review and approval before the tax rate can be set by the Board of Selectmen.

Every five years the DOR completes a comprehensive audit of the Town’s records and procedures for certification. The DOR’s last certification of the Town’s assessments and procedures was for FY 2020.

As part of the DOR certification process, preliminary assessed property values are made available for the public to review.
