Property valuation basics

Property valuation for tax purposes in Dorchester is administered by the City of Boston Assessing Department. Valuations determine your assessed value, which, combined with the municipal tax rate, establishes your property tax bill. Assessment methods, valuation cycles, and data sources are set by the Assessing Department; check the Assessing overview for procedures and contact information.[2]

Senior exemptions: eligibility and scope

Several exemption and relief options may be available to eligible seniors, including local exemptions and state tax credits. Exact eligibility criteria, income limits, asset tests, age thresholds, and the amount or percentage of exemption are documented on the Assessing Department pages and the Massachusetts Department of Revenue site; consult those official pages for the precise rules that apply to Dorchester residents.[1]

Senior exemptions may be combined with certain state credits subject to rules and limits.

Penalties & Enforcement

Enforcement of assessment, exemption applications, and unpaid property tax obligations involves multiple city offices. The Assessing Department makes valuation decisions; unpaid taxes and enforcement actions are handled by the Treasury/Collector. Official pages describe procedures for assessment notices, tax bills, liens, and collection processes.
