What the data shows for Connecticut

Primary signal

The median annual bill has a monthly reading

At the median, a Connecticut homeowner's $6,643 annual bill works out to about $554 a month on top of mortgage, insurance, and utilities, one reason the effective rate matters as much as the sticker price when comparing locations.

Decision signal 2

The statewide rate sits in the high-burden group

Connecticut carries one of the five highest average effective property tax rates in the country: 1.81%, ranked 3 of 51, versus a 0.92% national average.

Decision signal 3

A median-home worked example anchors the scale

A home at Connecticut's median value of $366,900 pays roughly $6,641 a year at the 1.81% state average rate, but about $7,411 at Greater Bridgeport Planning Region's 2.02% rate versus $5,210 at Northeastern Connecticut Planning Region's 1.42%.

Decision signal 4

More counties sit above the national rate than below

Of the 9 Connecticut counties with measured ACS 2024 data, 9 carry an effective rate above the 0.92% national average while 0 sit below it.

Decision signal 5

County rates stay in a tighter band

Property tax rates are unusually uniform across Connecticut: every county falls between 1.42% and 2.02%.

Reading these numbers correctly matters. An effective rate is a measured outcome, not a posted tax rate: it captures what typical homeowners actually paid after exemptions, assessment ratios, and every overlapping levy settled out. That makes it the most comparable single figure across county lines, where statutory mill rates are defined against different assessment bases and cannot be compared directly. Two counties with identical posted rates can produce very different real bills, and the reverse is just as common. Lenders use a similar logic when they estimate escrow: a percentage of value, calibrated to the taxing jurisdiction. Treat the figures here the same way, as a calibrated starting point that tells you which jurisdictions are expensive relative to home value, and confirm the exact bill with the assessor before you commit.

How This Calculator Works

The estimate multiplies your entered home value by a measured effective property tax rate: median taxes paid divided by median home value from Census Bureau ACS 2024 data, either for your selected Connecticut county or for the state as a whole.

This is a representative estimate, not your bill: actual Connecticut taxes depend on your assessed value, exemptions you qualify for, and municipal levies. Verify with your county assessor before making financial decisions.

Frequently Asked Questions

What is the typical property tax bill in Connecticut?
The Census Bureau's state-level ACS 2024 estimate puts Connecticut's median annual property tax at $6,643, on a median home value of $366,900. A home at a different price point scales roughly proportionally, which is what this calculator computes for you.
How does Connecticut compare to the national average?
Connecticut carries one of the five highest average effective property tax rates in the country: 1.81%, ranked 3 of 51, versus a 0.92% national average.
How much do property tax rates vary within Connecticut?
Across the 9 Connecticut counties with published ACS 2024 data, effective rates run from 1.42% to 2.02%. That spread is why choosing your county gives a much closer estimate than the statewide average.
How is my Connecticut property tax estimate calculated?
Your home value is multiplied by a measured effective rate: median taxes paid divided by median home value, from the Census Bureau ACS 2024 5-Year Estimates. Pick one of Connecticut's counties to use its own rate; leave it blank and the calculator applies the 1.81% statewide figure. In a high-tax state the county rate can differ sharply from the average, so selecting yours matters.
Does this estimate include exemptions?
No exemption specific to your situation is subtracted. Because effective rates blend exempt and non-exempt properties, a homestead, senior, veteran, or disability exemption you qualify for would pull your real Connecticut bill below this estimate; worth checking, since the dollar stakes are high at these rates. Your county assessor has the authoritative figure.
