The median homeowner in Northwest Hills Planning Region, CT pays about $5,593 a year in property tax on a home worth about $335,600, an effective rate of 1.67%. Connecticut as a whole is 1.81% and the US is 0.94%. Census ACS 2020-2024 5-year estimates.
The division
| Figure | Estimate | Margin of error (90%) |
|---|---|---|
| Median real estate taxes paid (B25103) | $5,593 | ± $131 |
| Median owner-occupied home value (B25077) | $335,600 | ± $8,278 |
| Effective rate = $5,593 ÷ $335,600 | 1.67% | ± 0.06% (3% of the rate) |
The margin on the rate follows the Census ratio formula: √(margin of taxes² + rate² × margin of value²) ÷ median value. City pages are published only when that margin is at most 20% of the rate; county pages are always published and say when they exceed it.
Informational only, not tax advice and not your bill. Two medians of different households are divided here; no home pays exactly this.

What homes here are worth since you bought
The Nw Hills County, CT home price page shows how much prices in the county have changed over 1, 5, 10 and 20 years from the FHFA index, and the calculator applies that index to what you paid. A median taxes figure beside a value that has moved since the survey window is one reason the rate here can differ from yours.
Where these figures come from
Source. The Census Bureau’s American Community Survey, ACS 2020-2024 5-year estimates, tables B25103 (median real estate taxes paid) and B25077 (median value), both for owner-occupied housing units, read from the ACS summary file and committed to this site (pulled 2026-10-08). Five-year estimates pool answers collected across the whole window, so the figures describe 2020 to 2024 together, not 2024 alone.
What the rate is and is not. It is the typical bill divided by the typical home value for the county, the same ratio sites that rank counties by property tax publish. It is not your bill: assessors value homes at a stated fraction of market value in many states, exemptions (homestead, senior, veteran) take a slice off before the rate applies, caps can hold a long-time owner’s assessment far below the market, and the millage itself differs between the school district, city and special districts inside one county. Taxes paid are what owners reported, after those exemptions. The guide to why your bill differs works through each.
Who is left out. Renters, and owners whose home is not their usual residence. Medians top-coded by the Census ($10,000+ in taxes, $2,000,000+ in value) have no exact value and those areas get no page.
ACS 5-year estimates are released each December (January when a release slips); this page updates with each pull. No ranking of counties or cities is published here on purpose: the margins of error overlap too often for an order to mean anything.
