Property taxes in Connecticut are administered at the county or local level and fund schools, roads, parks, libraries, emergency services, and local government operations. While the state sets the overall framework, your actual property tax rate depends on which county and city you live in — and rates can vary significantly within Connecticut itself. The 1.73% effective rate used in this calculator is the statewide average across all taxing jurisdictions.
The property tax calculation process begins with the county assessor determining your home's assessed value, which in Connecticut is typically based on recent sales of comparable properties in your area. If you believe your assessment is too high, you have the right to appeal — and many homeowners in Connecticut successfully reduce their assessments each year.
Property taxes are typically due in Connecticut on an annual or semi-annual schedule, depending on the county. Most mortgage lenders escrow property taxes, collecting 1/12 of the annual bill each month and paying the county on your behalf. If you own your home free and clear or your lender does not escrow, you are responsible for paying directly to avoid late penalties.

Local Mill Rate Variation
The 1.73% rate used in this calculator is the Connecticut statewide average. In practice, your actual rate depends on your specific county, city, school district, and special taxing districts. Rates can vary by 0.5–1.5 percentage points within Connecticut — homebuyers should research the specific rates in their target neighborhoods before purchasing.
Assessment vs. Market Value
Your county assessor values your property at the assessed value used to calculate taxes. While many states assess at 100% of market value, some assess at 80%, 60%, or even lower fractions. If Connecticut's assessments lag market values — common in rapidly appreciating markets — you may appear to pay a low effective rate even though your nominal rate is relatively high.
Exemptions and Relief Programs
While Connecticut may not have a broad statewide homestead exemption, specific relief programs exist for seniors, veterans, and disabled homeowners. Contact your county assessor's office to find out which programs you qualify for — these can meaningfully reduce your annual property tax burden.

Connecticut has an effective property tax rate of 1.73% for 2026. On the Connecticut median home value of $410,000, this works out to approximately $7,093/year or $591/month. The effective rate represents the actual percentage of home value paid in taxes, which may differ from the nominal mill rate used by your county assessor. Property taxes in Connecticut fund local schools, roads, parks, and government services.
Connecticut property taxes are calculated using the formula: Assessed Value × Tax Rate − Exemptions = Annual Tax. First, the county assessor determines your home's assessed value, which may equal market value or a fraction of it depending on the local assessment ratio. The tax rate (expressed as mills or a percentage) is set by local taxing authorities. In Connecticut, the effective combined rate across all taxing jurisdictions averages 1.73%. Then any exemptions, such as veteran or senior exemptions, are subtracted from the assessed value before calculating the final tax bill.
Connecticut does not have a statewide homestead exemption that reduces assessed value for all homeowners. However, some counties and municipalities in Connecticut offer local exemptions for primary residences, veterans, seniors, or disabled homeowners. Contact your county assessor's office to determine what exemptions you may qualify for and how to apply.
Connecticut's effective property tax rate of 1.73% is above the national average of approximately 1.10%. On a $410,000 home — the Connecticut median — you pay $7,093/year compared to the national average of $4,510/year, New Jersey's highest rate at $10,209/year, and Hawaii's lowest at $1,189/year. Keep in mind that states with low income taxes often have higher property taxes to compensate — total tax burden is a better comparison than any single tax type.
If you believe your Connecticut property assessment is too high, you can file an appeal with your county Board of Assessment Review or Equalization. Gather evidence that your home is over-assessed: recent comparable sales of similar homes in your area, an independent appraisal, or documentation of condition issues the assessor may have missed. Most Connecticut counties require you to file an appeal within 30–90 days of receiving your assessment notice. Successful appeals in Connecticut can reduce property taxes by $500–$3,000/year. Many property tax attorneys and consultants work on contingency — no fee unless they win your appeal.
