Central Connecticut Mill Rates, FY2026–27

What every town actually charges in property tax, what that costs on a real house, and the reason a lower mill rate does not always mean a lower tax bill. Rates below are for the October 1, 2025 grand list, billed from July 1, 2026.

Verified against each town's own assessor or tax collector on August 31, 2026.

Mill rates by town, lowest to highest

The dollar column shows the annual tax on a home assessed as if it were worth $350,000 at the town's last revaluation. Read the caveat below it before comparing towns.

Read this before comparing two towns

The dollar figures above are illustrative, not quotes. Connecticut assesses property at 70% of its value as of the town's last revaluation date: not today's market. Ellington and Somers revalued for this grand list, so their assessments are current. Vernon, Manchester and East Hartford last revalued in 2021, which means a house selling for $350,000 today is very likely assessed at less than $245,000 there, so their real bills run lower than this table suggests. Vernon, Manchester, East Hartford and Hebron all revalue for the 10/1/2026 grand list, which will move their rates substantially. For an actual number, look up the specific property's assessment on the town's field card.

How to work out your own tax bill

1. Find your assessed value.It's on your tax bill or the town assessor's property card: not something you calculate from today's market price. It is 70% of what the town valued the home at during its last revaluation.
2. Multiply by the mill rate. Assessed value × mill rate.
3. Divide by 1,000.That's your annual tax.
4. Add any district. If the property sits in a special services, fire, or lake district that levies its own rate, add it to the town rate before you calculate.

Worked example. A home assessed at $245,000 in a town with a 30.00 mill rate: $245,000 × 30.00 ÷ 1,000 = $7,350 per year.

Town-by-town notes

Somers

Below the state vehicle cap, so cars are taxed at the town rate.

Coventry

Several small lake and homeowner districts levy their own additional rates, which matters if you are buying in one of those neighborhoods.

Ellington

Revalued for this grand list, which is why the rate dropped sharply from the prior year. The Crystal Lake Fire District does not levy a mill rate.

East Windsor

Below the state vehicle cap, so vehicles are taxed at the town rate. Two small fire districts add to the real estate/personal property rate only: Broad Brook Fire Department adds 1.93 mills and Warehouse Point Fire District adds 2.27 mills. Verified against Connecticut OPM's official statewide mill rate dataset (drawn from town certifications).

Marlborough

Revalued for the October 1, 2025 grand list, which is why the rate dropped sharply from 37.74 the prior year — a real assessment change, not a tax cut. Single town-wide rate, no separate districts. Verified against Connecticut OPM's official statewide mill rate dataset (drawn from town certifications).

Windham

Base town rate; below the state vehicle cap, so cars are taxed at the town rate outside district add-ons. Two taxing districts add to it: the Windham First Taxing District adds 2.00 mills (both real estate and motor vehicle, for 29.85 total — matches the town's own published Town & First Taxing District rate), and the Willimantic Taxing District adds 9.97 mills real estate / 4.61 motor vehicle, for 37.82 real estate and the statewide 32.46 motor vehicle cap. Willimantic holds most of the town's population, so most listings there carry the higher combined rate. Verified against Connecticut OPM's official statewide mill rate dataset (which draws directly from town certifications), cross-checked against the town's own published First Taxing District figure.

Glastonbury

Amended to 33.73 in June 2026; some third-party sites still show the earlier 33.81.

Vernon

Single town-wide rate. Vernon has no separate fire district levy. Revalues for the 10/1/2026 grand list, so expect the rate to change substantially next year.

Manchester

The Downtown Special Services District adds 4.18 mills (45.18 total), a small commercial district, not most residential addresses. Since the Eighth Utilities District and South Fire merged, there are no longer separate fire district rates. Revalues for the 10/1/2026 grand list.

East Hartford

Revalues for the 10/1/2026 grand list.

Towns we can't confirm yet

We publish a rate only when we can verify it against the town's own source. For these towns we can't, so we'd rather say so than print a number you might budget against.

Hebron

Hebron has not published a rate for this grand list. The town ran multiple budget referenda in 2026 and its own pages still show the prior year. Call the tax collector for the current figure.

Stafford

Two different figures are circulating after Stafford's budget passed at a fourth referendum in July 2026, and the town's own mill rate history has not been updated. Stafford also has a service district that levies separately. Call the tax collector before relying on a number.

Connecticut property tax questions

What is a mill rate?

A mill is one dollar of tax for every $1,000 of assessed value. A rate of 30 mills means $30 of tax per $1,000 assessed. In Connecticut your assessment is 70% of market value, so the formula is: market value × 0.70 × mill rate ÷ 1,000.

Does a lower mill rate mean lower taxes?

Not necessarily, and this trips up most buyers. Your assessment is 70% of what your home was worth on the date of that town's last revaluation: not today. A town that revalued recently has higher assessments and therefore a lower mill rate; a town that hasn't revalued in years has stale, lower assessments and a higher rate. Comparing two towns by mill rate alone can point you the wrong way. Compare actual tax bills on comparable homes instead.

How much are property taxes on a $350,000 house in Connecticut?

It depends entirely on the town. At an assessment of 70% of value, a $350,000 home is assessed at $245,000. Across the towns on this page that works out to roughly $5,748 a year at the low end and $11,574 at the high end: a difference of thousands of dollars annually on the same house.

Why is my car taxed at a different rate?

Connecticut caps the motor vehicle mill rate statewide at 32.46 mills. In towns whose regular rate is higher than the cap, vehicles are taxed at 32.46 instead. In towns below the cap, vehicles are taxed at the town's normal rate.

When do mill rates change?

Annually. Rates take effect July 1 and are set on the previous October 1 grand list. Most towns adopt a rate between March and May, but towns that pass budgets by referendum can run into July or later. We re-check every town on this page against its official source each year.
