What Is the Connecticut Property Tax Rate?
The Connecticut property tax rate is not one flat number — it is the combined result of your county, city, township, and school-district rates, applied to your home’s assessed value. Across Connecticut, homeowners pay about 1.54% of their home’s value on average, or around $6,643 a year on a typical $366,900 home. That puts Connecticut near the top nationally — ranked #3 of 50 states from highest to lowest. Two
homes worth the same amount can still owe very different bills depending on the town and school district, so treat the statewide figure as a starting point, not your exact bill.
If your bill went up, start by reading the assessed value on your notice and confirming the details the town has on file for your home are correct — an error there can raise a bill on its own. Next, ask your town assessor’s office which exemptions or the elderly/disabled circuit-breaker credit you may qualify for, since many homeowners are eligible and don’t realize it. If the assessed value still
looks too high compared to what your home would sell for, you generally have the right to appeal to your town’s Board of Assessment Appeals — check your notice or your town assessor for the current filing window.

How Connecticut Property Tax Is Calculated
Your Connecticut property tax starts with an assessed value set by Local municipal assessors — each of Connecticut’s 169 towns and cities has its own assessor’s office (there is no county assessor, because Connecticut has no county government). Your town or city assessor determines your property’s value.. Connecticut assessors estimate your property’s fair market value, then apply a uniform assessment ratio set by state law to arrive at the assessed
value that your tax is actually based on.
Look at the assessed value printed on your assessment notice or tax bill — that figure, not the full market value, is what your bill is calculated from (see the data box above for the ratio). That assessed value is then multiplied by the combined local tax rate to produce your bill. In Connecticut, property is generally reassessed Every town must revalue all real property on a regular cycle set
by state law — generally at least once every five years — with the timing staggered across towns, so your town’s most recent revaluation year may differ from a neighboring town’s.
Check your assessment notice for when your town last revalued.. The single most important number to check is your assessed value: if it is higher than what your home would sell for, your bill is too high — and that is exactly what an appeal fixes.
The actual rates in Connecticut are set by Each individual municipality (town or city) sets its own rate — expressed as a “mill rate” — every year based on its local budget. There are no county tax rates in Connecticut; the rate is purely local, so it varies from town to town.. That is why your neighbor one town over can pay a different bill on an identical house.
Where Your Connecticut Property Tax Money Goes
Connecticut property taxes are overwhelmingly local and fund town and city services — public schools are usually the largest share, along with police and fire, roads, libraries, and other municipal services. Because Connecticut has no county government, towns rely heavily on the property tax to pay for these services. For most Connecticut homeowners, the school-district share is the biggest single piece of the bill, which is why property taxes tend

to be highest where schools rely most on local funding.
One Connecticut note: Connecticut’s defining feature is that property tax is administered entirely at the town/city level — there are no counties and no county assessors, and each of the 169 municipalities runs its own assessment and billing. The state Department of Revenue Services does not administer the property tax; the state Office of Policy and Management provides guidance, but your bill, mill rate, and assessment all come from your
town.
How Connecticut Property Tax Compares
The U.S. average property tax bill is about $4,271 a year. The typical Connecticut bill of $6,643 is $2,372 above that. Remember that a low rate does not always mean a low bill — a state with cheap rates but expensive homes can still cost you more than Connecticut. The dollar bill and your own assessment matter more than the headline rate.
How to Lower Your Connecticut Property Tax
You cannot change the Connecticut property tax rate, but you have two real levers on your own bill. First, claim every exemption you qualify for. Connecticut offers a number of property tax relief programs that can lower your bill, including exemptions and credits for homeowners age 65 and older, veterans (with added relief for those with service-connected disabilities), and residents who are blind or totally and permanently disabled, plus a
state-funded circuit-breaker credit for qualifying elderly and disabled homeowners.
Most are applied for through your local town assessor’s office, and some require you to reapply or recertify income periodically — it’s worth checking whether you qualify (see the data box above for any amounts). Second, appeal your assessment if your home is valued higher than it would sell for — studies suggest a large share of homes are over-assessed, and appeals often succeed.
Don’t want to appeal your Connecticut taxes yourself? A property tax appeal service can file everything for you and usually only charges if it wins — typically a share of what it saves you. It is one option; you can also appeal on your own for free.
