Property Tax Bills Across New London County, Connecticut
Property tax bills in New London County are based on a home’s assessed value, which is tied to its market value, and the local tax rate set by the municipality. When a property’s assessed value rises, the tax bill usually rises too, even if the homeowner’s income does not change. Local budgets, school funding, and other public services also influence how much tax is collected.
With a median home price of $192,015, property taxes can take a significant share of housing costs. The county’s tax bills vary widely, with the 25th percentile at $4,135, the 75th percentile at $7,047, and the 90th percentile at $9,456. That range shows how much location and property value can affect what homeowners pay.
Some areas face especially high bills, such as Noank, where the highest median tax bill is $11,573, while Lyme has the lowest median tax bill at $2,693. For homeowners, this means two similar homes can have very different tax burdens depending on where they are located and how they are assessed.
