  • About This Answer

    To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county.

Connecticut Property Taxes

Connecticut homeowners pay among the highest property taxes in the country. The state’s average effective property tax rate (taxes as a percentage of home value) is 1.83%, which ranks as the eighth highest of any state. Connecticut is unusual in that counties are not responsible for administering the property tax. Instead, cities and towns set rates and collect property taxes. Below, we will look at the local rates across the state of Connecticut and other important property tax rules.

How Connecticut Property Taxes Work

Property taxes in the state of Connecticut are administered entirely by cities and towns. While the state does have some oversight of the process, homeowners deal almost entirely with local officials. Assessors assigned by the local municipality valuate property to determine its fair market value. By law, this must happen at least once every five years, but assessments can be more frequent than that.

Once a property’s fair market value has been established, the statewide assessment ratio of 70% is applied. This means that a property’s assessed value is equal to 70% of the home’s market value. The homeowner does not pay taxes on market value but on this lower, assessed value. So, for example, if your home is worth $500,000, the assessed value will be $350,000.

If you do not yet have a home in Connecticut but are looking to purchase one, check out our guide to Connecticut mortgage rates and getting a mortgage in Connecticut before you make the move.

Connecticut Property Tax Rates

Municipalities in Connecticut apply property taxes in terms of mill rates. A mill rate is equal to $1 in tax for every $1,000 in assessed value. To calculate your tax based on your mill rate, divide your assessed value by 1,000 and multiply the result by your rate.

So, for example, a home with a market value of $500,000, an assessed value of $350,000 and a mill rate of 50 would have annual property taxes of $17,500.

The table below shows the average effective property tax rates for each of Connecticut’s 8 counties. An effective property tax rate is equal to taxes paid as a percentage of home value. The U.S. average effective property tax rate is 1.19%.

Rank County Property Tax Rate School Rating Crimes Per 100k People

Methodology

Our study aims to find the places in the United States where people are getting the most for their property tax dollars. To do this we looked at school rankings, crime rates and property taxes for every county.

As a way to measure the quality of schools, we calculated the average math and reading/language arts proficiencies for all the school districts in the country. Within each state, these schools were then ranked between 1 and 10 (with 10 being the best) based on those average scores.

For each county, we calculated the violent and property crimes per 100,000 residents.

Using the school and crime numbers, we calculated a community score. This is the ratio of the school rank to the combined crime rate per 100,000 residents.

We used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.

Finally, we calculated a tax value by creating a ratio of the community score to the per capita property tax paid. This shows us the counties in the country where people are getting the most bang for their buck, or where their property tax dollars are going the furthest.
