Property Taxes in Connecticut: Assessed Value and Mill Rates

In order to calculate your property taxes in Connecticut. You will need the assessed value of your property and mill rates.

What makes up the Assessed Value?

The Assessed Value of a property is 70% of the appraised value.  It’s important to know the difference between the Appraised value and Assessed Value.

The appraised value of the property is the price of the property set by the town.  Usually, Town Assessors will determine this by comparing the value of comparable properties and will usually send an inspector to physically inspect the property. The appraised value is composed of a Land Value and a Building Improvements Value and the total will be your appraised value. By law, towns are required to revalue properties at least once every 5 years (CGS 12-62b(1)). As part of revaluation, town inspectors from the Town Assessors office will conduct physical inspections of the properties by walking the exterior of the property. If there are discrepancies in square footage or new building improvements, you will be reassessed.

What is the Mill Rate?

Every town sets its own Mill rate and Mill rates are adjusted every year.  Most towns publish their mill rates in May.  For example, the Board of Estimate and Taxation in Greenwich sets the mill rate in May of every year.

A mill represents $1 for every $1000 in assessed property value.  For example, Greenwich has a mill rate of 11.689 mills which means a home with a $1,000,000 assessed value has a property tax of $11,689 a year.

How to Calculate Property Taxes in Connecticut?

This is how to calculate property taxes in Connecticut.  First, take the 100% appraised value of the property and multiply by 70% to get the assessed value.  Then you multiply the assessed value of the property by the mill rate and divide by 1,000.  For example, a property with a 100% appraised value of $2,000,000 in Greenwich will have a property tax of $15,916.60.

Take 70% of Appraised Value: $2,000,000 x 0.70= $ 1,400,000

Multiply Assessed Value by Mill Rate: $1,400,000 x 11.682= $16,354,800

Divide by 1000: $16,354,800 /1000= $16,354.80
