About the Colchester Property Market
Colchester is a city located in New London County, Connecticut. Every property inside the Colchester city limits is assessed by the New London County assessor, which applies Connecticut property tax rules uniformly across the county.
Because Colchester property values are set at the county level, the same assessment rules apply to homes throughout the city. Homeowners who believe their Colchester home is over-assessed have the right to file a appeal directly with New London County.
Connecticut allows the assessor to defend or adjust the assessed value during a appeal, so Colchester homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Colchester Property Market Context
Colchester homeowners navigate the same Connecticut assessment system as every other community in the state, but local market dynamics mean over-assessments here have their own character.
Connecticut market character
Connecticut has some of the highest effective property tax rates in the country at around 2.0%, and assessed value equals 70% of fair market value. Towns revalue on a five-year cycle, and a missed revaluation can leave homeowners badly over-assessed for years.
How Connecticut handles appeals
Connecticut homeowners appeal first to the Board of Assessment Appeals, then to Superior Court for larger cases. Filing an appeal does not risk an increase in assessed value.
When to file in Colchester
BAA filing deadline is February 20 (or the next business day). Missing this window locks in your assessment for another year.
