How is Appraised Value Calculated in Connecticut?

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 Improvement Value and the total will be your appraised value.

By law, Connecticut towns are required to revalue properties at least once every 5 years (CGS 12-62b(1)). As part of revaluation, Connecticut 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.

A mill represents $1 for every $1000 in assessed property value. For example, Greenwich has a mill rate of 11.28 mills which means a home with a $1,000,000 appraised value has a property tax of $7,896 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 $22,560.

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

Multiply Assessed Value by Mill Rate: $1,400,000 x 11.28= $15,792,000

Divide by 1000: $15,792,000 /1000= $15,792
