View Dedham updates on COVID-19. Town Hall remains closed to the public until further notice, but Town staff are providing services remotely.


Located on the second floor of the Ames Building, the Assessors Department:

  • Assesses the value of all real estate and personal property in Dedham.

  • Oversees excise tax on motor vehicles, boats, and trailers.

  • Processes applications for tax exemptions for the elderly, disabled veterans, widows and widowers, and blind or visually impaired citizens.

When to Contact us

Please contact our department with questions about assessments or the assessed value of your property, but not about the tax rate itself as our department does not raise or lower taxes nor do we make the laws. We also administer excise taxes, applications for exemptions, and abatement requests.

Tax Rates for Fiscal Year 2020

Tax rates are calculated per $1,000 of assessed value. The rates are updated each December. Each fiscal year ends on June 30, so the first two quarterly bills of each fiscal year are preliminary. 

$13.72 $28.70

Board and Committee Work

This Assessors Department works with the Board of Assessors. The board oversees the annual valuation of real estate and personal property within Dedham for taxation purposes.
