How this compares nationally
The population-weighted average modeled rate across indexed Connecticut counties is 2.12%. That modeled effective rate is above the broad national band many surveys use for orientation (often roughly 1–1.3% of home value, varying by source and methodology)—state and county structures differ widely.
Orientation band (~1–1.3%): broad U.S. survey context. See Tax Foundation — Property taxes as a percentage of owner-occupied housing value (state / local, illustrative national context).

FAQ
Common questions
Statewide orientation for Connecticut—open a county page for parcel-level rules.
What do these Connecticut county pages show?
Each Connecticut county page uses ACS 2021 5-year county medians (traditional counties—the latest ACS county file before planning regions replaced them in Census tabulations), with Title 12 and OPM references. Property tax is municipal—town grand lists and mill rates drive bills.
Why is the statewide average different from one Connecticut county?
Connecticut has 8 traditional counties in this index; the hub averages population-weighted implied rates using ACS 2021 county populations (B01003) aligned with the same survey vintage as medians. Municipal mill rates still vary inside each county.
When are property taxes due in Connecticut?
Connecticut property taxes are billed by municipalities; many towns offer July 1 and January 1 installments for the fiscal year—your tax collector notice states exact due dates.
How should I compare Connecticut counties to the rest of the U.S.?
Connecticut pages use ACS 2021 county medians—useful for burden comparisons across counties, but town mill rates on 70% grand list assessments drive actual bills. Compare to national statistics only when definitions match. See our national context note and Rate Gazetteer’s methodology page.
