How Connecticut property taxes and the conveyance tax work
Connecticut does property taxes differently from most states: there is no single statewide rate. Every town sets its own mill rate each year, and that one local decision can swing your monthly payment by well over a thousand dollars on the same-priced home.
Assessment and the mill-rate formula
Connecticut properties are assessed at 70% of fair market value. Your annual property tax is your assessed value, divided by 1,000, multiplied by your town's mill rate — one mill equals one dollar of tax per $1,000 of assessed value.
Annual tax = (assessed value ÷ 1,000) × mill rate, where assessed value = 70% × fair market value.For the 2025–26 fiscal year, town mill rates ranged from 10.85 mills in Washington to 68.95 mills in Hartford, with an average of 28.22 mills. Because the rate is set locally, effective property tax rates are best described as a town-varying range — roughly 1.5% to 2.0% of market value in many communities — never as one statewide figure.
of fair market value is the assessed value Connecticut taxes are based on.
Range of town mill rates for 2025–26, from Washington (lowest) to Hartford (highest); average 28.22.
Typical effective tax-rate range as a share of market value — it depends on your town, not the state.
The conveyance tax — paid by the seller
Connecticut charges a real estate conveyance tax at closing, and it is paid by the seller, not the buyer. The state portion is tiered on the sale price:
| Portion of sale price | State rate |
|---|---|
| First $800,000 | 0.75% |
| $800,001 – $2,500,000 | 1.25% |
| Above $2,500,000 | 2.25% |
On top of the state tax, there is a municipal conveyance tax of 0.25% in most towns, rising to up to 0.50% in targeted investment communities. As a buyer it is not your closing cost — but it matters if you are selling a Connecticut home to buy your next one.
2026 conforming loan limits follow planning regions
Connecticut's 2026 conforming loan limits are set by planning region, not by county. The baseline limit is $832,750 in most regions, $851,000 in the Naugatuck Valley region, and $977,500 in the Greater Bridgeport and Western Connecticut regions. Loans above your region's limit are priced as jumbo — one of the situations where shopping across many lenders matters most.
Worked example: a $450,000 Connecticut home
Here is the exact math behind this calculator's default tax figure, step by step:
| Fair market value (sale price) | $450,000 |
| Assessed value (70% × $450,000) | $315,000 |
| Annual tax at the average 28.22 mills — ($315,000 ÷ 1,000) × 28.22 | $8,889.30 / yr |
| Monthly tax escrow at the average rate | $740.78 / mo |
The same home in the state's lowest- and highest-mill towns shows why the town matters more than the state average: at Washington's 10.85 mills the tax is about $3,418 a year, while at Hartford's 68.95 mills it is about $21,719 a year — a difference of roughly $1,525 a month on an identical $450,000 home.
Conveyance tax on the same sale (seller-paid): the state portion is 0.75% × $450,000 = $3,375, and the municipal portion at 0.25% is $1,125 — $4,500 total, owed by the seller at closing.

Connecticut mortgage FAQs
How are property taxes calculated in Connecticut?
Connecticut assesses real property at 70% of its fair market value. Your annual tax is (assessed value ÷ 1,000) × your town's mill rate. Each town sets its own mill rate annually — for 2025–26 the range ran from 10.85 mills in Washington to 68.95 mills in Hartford, with an average of 28.22 mills.
Who pays the conveyance tax in Connecticut — the buyer or the seller?
The seller pays the Connecticut conveyance tax. The state portion is tiered: 0.75% on the first $800,000 of the sale price, 1.25% on the portion from $800,001 to $2,500,000, and 2.25% on the portion above $2,500,000. There is also a municipal conveyance tax of 0.25% in most towns, and up to 0.50% in targeted investment communities.
What are the 2026 conforming loan limits in Connecticut?
Connecticut's 2026 conforming loan limits are set by planning region rather than by county. The baseline limit is $832,750 in most regions, $851,000 in the Naugatuck Valley region, and $977,500 in the Greater Bridgeport and Western Connecticut regions.
Why do Connecticut property taxes vary so much from town to town?
Because every Connecticut town sets its own mill rate each year based on its budget and grand list. In 2025–26, mill rates ranged from 10.85 in Washington to 68.95 in Hartford. On the same $450,000 home assessed at $315,000, that spread means roughly $3,418 a year in Washington versus roughly $21,719 a year in Hartford. Effective tax rates generally fall in a range of about 1.5% to 2.0% of market value, depending on the town.
