How rates are spread

Number of Connecticut towns in each mill rate band, FY2027 (mills)

Reading these rankings

The median mill rate in Connecticut is 27.470 mills. Half of towns are above it and half below.

Connecticut doesn't publish an effective rate, so these rankings use the rate itself. Assessments relative to market value differ from town to town, so use them as a guide, and the town page's calculator for a bill.
