About the Charlestown Property Market
Charlestown is a city located in Suffolk County, Massachusetts. Every property inside the Charlestown city limits is assessed by Boston Assessing Department, which applies Massachusetts property tax rules uniformly across the county.
Because Charlestown property values are set at the county level, the $680,000 county median home value and 1.08% effective tax rate apply to homes throughout the city. Homeowners who believe their Charlestown home is over-assessed have the right to file a abatement directly with Boston Assessing Department before the February 1 deadline.
Under Massachusetts law, a abatement cannot increase your assessed value — it can only stay the same or go down. That makes a Charlestown abatement a low-risk way to push back against an over-assessment, especially for homeowners with strong comparable sales evidence.
Charlestown Property Market Context
As a city in Massachusetts, Charlestown inherits the state's assessment framework — which shapes how over-valuations occur and how homeowners can fight them.
Massachusetts market character
Massachusetts assessed values are based on prior-year sales and must reflect full and fair cash value. Prop 2 1/2 caps aggregate tax-levy increases, but individual assessments still fluctuate annually and can be wildly out of line with market value.
How Massachusetts handles abatements
Massachusetts uses an "abatement" process rather than appeal. File with the local Board of Assessors, then appeal to the state Appellate Tax Board if denied. Filing carries no risk of increase.
When to file in Charlestown
Abatement applications are due by February 1 of each year (or the deadline printed on your tax bill). This is one of the earliest deadlines in the country.
