  • 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

On a nationwide scale, Connecticut homeowners pay the fourth highest property taxes in the U.S. The state’s average effective property tax rate is 2.07%, which is almost double the 1.08% national average.

Connecticut is unusual in that counties are not responsible for administering property taxes. Instead, cities and towns set rates and collect the taxes.

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 how to get a mortgage there before you make the move.

A financial advisor in Connecticut can help you understand how homeownership fits into your overall financial goals. Financial advisors can also help with investing and financial plans, including taxes, homeownership, retirement and more, to make sure you are preparing for the future.

How Connecticut Property Taxes Work

Cities and towns alone administer all property taxes in the state of Connecticut. While the state does have some oversight of the process, homeowners deal almost entirely with local officials. The local municipality assigns assessors who 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 its market value. The homeowner does not pay taxes on market value, but rather on the lower assessed value. For example, if your home is worth $500,000, the assessed value comes out to $350,000.

Connecticut Property Tax Rates

Municipalities in Connecticut apply property taxes in terms of mill rates. A mill rate is equal to $1 in taxes 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 mill rate.

In turn, a home with a market value of $500,000, and consequently a $350,000 assessed value and a mill rate of 50, would pay $17,500 in annual property taxes.

The table below shows the average effective property tax rates for each of Connecticut’s eight 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 1.08%.

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 analyzed the math and reading/language arts proficiencies for every school district in the country. We created an average score for each district by looking at the scores for every school in that district, weighting it to account for the number of students in each school. Within each state, we assigned every county a score between 1 and 10 (with 10 being the best) based on the average scores of the districts in each county.

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.
