How Connecticut Property Tax Works
In Connecticut, your property tax starts with the assessed (taxable) value of your home, which is then multiplied by the local tax rate. The state's assessment basis is 70% of the town's assessed value (Connecticut assesses at 70% of market value), then taxed by municipal rates. The average effective property tax rate in Connecticut is approximately 1.96% of home value, though your actual rate depends on your county, city, school district, and any exemptions you claim.
This guide explains the system in plain language so you can check your bill, claim every exemption you qualify for, and appeal if your assessed value looks wrong.
Connecticut Assessment & Revaluation
- Assessment basis: 70% of the town's assessed value (Connecticut assesses at 70% of market value), then taxed by municipal rates.
- Revaluation cycle: on a 5-year revaluation cycle by town, with large jumps in revaluation years.
- Who sets the rate: Tax rates are set locally by your county, city, school district, and any special districts, then applied to your assessed value.
- Your bill: Assessed value × total local rate − exemptions = tax due.

Homestead Exemption in Connecticut
Connecticut offers a local-option homeowners' exemption (e.g., $10,000 to $50,000 of assessed value) and a larger exemption for seniors and disabled owners.
- Seniors: Towns grant a senior exemption and a circuit-breaker (income-based) credit for owners 65+; the benefit varies by town.
- Veterans & disabled: Disabled veterans (100% service-connected) and surviving spouses receive a full or partial exemption under the state veterans exemption.
- File every year: Most Connecticut exemptions must be applied for with the county assessor; they do not appear automatically on a new purchase.
How to Lower Your Connecticut Property Tax
1. File an Assessment Appeal
If your assessed value is higher than what similar Connecticut homes sell for, you can appeal. The deadline is by the February board deadline, to the local Board of Assessment Appeals. Gather recent comparable sales and the assessed values of nearby homes, then present them to your local board. A successful appeal lowers the base value and therefore every future bill.
2. Claim Every Exemption
Verify you receive all eligible relief: the homestead exemption, the senior/disabled programs, and any veteran exemption. Contact your county assessor to confirm you are not missing a saving you qualify for.
3. Watch Reassessment Triggers
Improvements, a change of ownership, or a periodic revaluation can raise your assessed value. Knowing your county's on a 5-year revaluation cycle by town, with large jumps in revaluation years helps you predict and prepare for bill changes rather than being surprised by them.

Property Tax Payment in Connecticut
Most Connecticut homeowners pay property tax through an escrow account included in their monthly mortgage payment, or in installments directly to the treasurer. Missing a deadline adds penalties and interest, so mark your payment dates and watch for the assessment and tax notices each year. If you escrow, your lender forwards the payment — but you should still read the annual notice to catch errors.

Frequently Asked Questions — Connecticut
What is the average property tax rate in Connecticut?

When is the property tax appeal deadline in Connecticut?

Does Connecticut have a state income tax?

Are Connecticut property taxes deductible on federal returns?

How can I lower my Connecticut property tax bill?

Calculate My Property TaxWhat Makes Connecticut Property Tax Unique
Connecticut's 70% assessment ratio means taxable value is well below market, but municipal rates are high, producing some of the highest bills in the country
Because relief is set locally, two homes in different towns can get very different exemptions.
- Connecticut assesses at 70% of market value, not full value.
- Revaluation is every 5 years, producing big bill jumps in those years.
- Relief is local-option, so it varies town by town.
- 100% disabled veterans receive a full exemption.
Understanding the Connecticut Tax Rate
The headline "1.96%" is an average effective rate — the tax paid as a share of home value. Your real bill is built from several local levies (county, city, school, and special districts) added together and applied to your assessed value after exemptions. Because each district sets its own rate, two neighbors a block apart can owe different amounts. The best way to understand your own rate is to read the annual assessment and tax notice line by line and match each levy to the district that charges it.
Appealing Your Assessment in Connecticut
If your assessed value exceeds the market value of comparable Connecticut homes, you can appeal. The window is by the February board deadline, to the local Board of Assessment Appeals. Prepare recent comparable sales, the assessed values of similar nearby homes, and any evidence of condition issues. A successful appeal lowers the taxable base, which then flows through to every future bill — not just the current year.
Worked Connecticut Example
A homeowner buys a $350,000 primary residence in Connecticut. At the state's average effective rate of about 1.79%, the annual property tax is roughly $6,265. If the home's market value rises over time but the assessment is capped or grows slowly under state rules, the owner keeps the bill far closer to the purchase-year figure than to a tax on full market value — a saving that compounds for as long as they stay. Our calculator models the dollar result once you know your county rate.
Connecticut Property Tax for Long-Time & Senior Owners
A Connecticut senior should check the town's local exemption and circuit-breaker credit, because both are income-based and vary widely by municipality. Because Connecticut's system is built around the assessed value and local levies, the most valuable habit is simply staying aware of revaluation triggers and filing every exemption you qualify for each year. Reviewing your annual assessment notice is the simplest way to catch an error before it costs you, and it keeps your exemptions current.
