How Property Taxes Work in Connecticut
In Connecticut, your town assessor estimates your home's value, and property is taxed at 70% of fair market value at the last revaluation. Your bill is that assessed value, minus any exemptions, multiplied by the combined tax rate of every local government that covers your property, usually your county, city, school district, and any special districts.
The Connecticut Office of Policy and Management oversees property tax administration in Connecticut and publishes guidance on assessments, exemptions, and appeals.
Our median effective property tax rate (tax bill ÷ assessor's market value) accounts for exemptions and deductions, making it more accurate than the general median tax rate, which is the midpoint of statutory rates before adjustments.

Every property tax bill comes from three inputs:
Assessed Value
A local assessor or appraisal district estimates your home's market value. Many states then apply an assessment ratio. For example, Georgia taxes homes at 40% of market value, while Texas uses 100%. Some states, like California, cap how fast assessed values can rise for homestead properties.
Exemptions
Homestead, senior, veteran, and disability exemptions reduce the taxable value of qualifying homes, usually for a primary residence only.
Tax Rates
Each taxing authority that covers your property, typically a county, city, school district, and sometimes special districts, sets its own rate. Rates are usually expressed as millage (dollars per $1,000 of taxable value) or as a rate per $100 of value.
Your bill is your taxable value (assessed value minus exemptions) multiplied by the combined tax rate.
What is the Median Effective Property Tax Rate?
Our median effective property tax rate (tax bill ÷ assessor's market value) accounts for exemptions and deductions, making it more accurate than the general median tax rate, which is the midpoint of statutory rates before adjustments. Because states and counties assess property differently, the effective rate is the clearest way to compare bills across Connecticut.
