Connecticut Property Tax Calculator
Figure basis: Official US Census Bureau, American Community Survey 5-year estimatesThis Connecticut property tax calculator estimates the annual property tax on a home using the state's median effective property tax rate, which the US Census Bureau reports as 1.92% of a home's value. Enter a home value to see the estimated yearly property tax at that median rate. The Census figure is derived from the median real estate taxes paid in Connecticut ($6,575) divided by the median home value ($343,200), from the American Community Survey 5-year estimates. Property tax in the United States is set locally, not by the state, so your actual rate depends on your county, city, school district and any special districts, and on how your property is assessed. Two homes of the same value in different counties of Connecticut can have noticeably different bills. Use this as a sound statewide benchmark, then check your county assessor for your property's assessed value and the exact local millage rate, plus any homestead or senior exemptions you qualify for. The median real estate taxes and median home value here are official Census figures; the effective rate is the simple, disclosed ratio of the two.
Connecticut's median effective property tax rate is 1.92% of home value (Census: median tax $6,575 on a median home worth $343,200). On a $400,000 home that is about $7,680 a year.
How Connecticut property tax is estimated
estimated annual property tax = home value x effective rate / 100
Connecticut median effective rate = median real estate taxes / median home value x 100
= $6,575 / $343,200 x 100 = 1.92%
Property tax is levied by local governments, so your exact rate is set by your county and municipality, not the state. The median rate above is a benchmark; check your county assessor for the assessed value and local millage that apply to your home.
Property tax by county in Connecticut
Property tax is set locally, so the statewide median above hides a wide spread. These are the US Census Bureau's median figures for all 9 counties in Connecticut: the median home value, the median real estate taxes actually paid, and the effective rate (taxes divided by value). The spread runs from Western Connecticut Planning Region at 1.42% to Greater Bridgeport Planning Region at 2.02%, against a state median of 1.92%. Click a column heading to sort.

Why Connecticut's bill is so high
Connecticut carries the heaviest property tax burden in this group by far: a 1.92% median effective rate and a median bill of $6,575, among the highest in the nation. A big reason is structural. Connecticut has no county government, so towns and cities shoulder schools and services almost entirely through the property tax, and mill rates vary sharply from one town to the next.
Assessments run at 70% of fair market value, and each municipality must revalue property on a five-year cycle, so a townwide revaluation can shift your assessed value even in a year when the mill rate holds steady. Connecticut is also one of the states that taxes motor vehicles as personal property, billing them at the local mill rate, though the state now caps the mill rate that can be applied to vehicles to limit how much high-mill towns can charge on cars.
The practical effect is wide variation around the 1.92% median: a home in a wealthy, low-mill suburb can pay a very different effective rate than an identical home in a high-mill city, even though both use the same 70% assessment ratio. Check your town's current mill rate, your latest revaluation, and any local elderly or veterans' relief before treating the median as your own number.
