List of mill rates in CT: every town's rate explained

Last updated 2026-07-09

What is a mill rate and how does it work in Connecticut?

A mill rate is the tax charged per $1,000 of assessed value. One mill is $1 per $1,000. So a 30-mill rate on a home assessed at $200,000 produces a $6,000 tax bill.

Connecticut fixes assessed value at 70% of fair market value by statute. That 70% figure is the assessment ratio, set in Connecticut General Statutes Section 12-62a ^[1]. A home that sells for $400,000 should be assessed at $280,000. Multiply that by 0.03000 (a 30-mill rate written as a decimal) and you owe $8,400 a year.

The rate itself gets set each spring by the local legislative body, usually a town council or board of finance, once they know the budget and the total assessed value of everything in town. If the grand list grows, the rate can fall even while spending rises. That's why two towns can post very different mill rates and still charge similar bills. One spreads the load across a big commercial base. The other leans on homeowners.

Connecticut rates are written in full mills plus fractions, sometimes to two or three decimal places. A rate listed as 32.46 means $32.46 per $1,000 of assessed value.

What are the current mill rates for every town in Connecticut?

The Office of Policy and Management (OPM) publishes a full table of municipal mill rates each fiscal year ^[2]. The table below shows the 2024-25 rates (effective on the October 1, 2023 grand list) for all 169 Connecticut municipalities, sorted alphabetically. A handful of towns set separate rates for real property, personal property, or motor vehicles. Where that split exists, the real-property rate is listed.

Note: Mill rates change every fiscal year. These figures reflect the rates adopted for 2024-25 as reported by OPM ^[2]. Confirm the current rate with your town's tax collector before you calculate an appeal, because some towns do interim adjustments. Motor vehicle mill rates are capped at 32.46 mills statewide under a 2022 budget law ^[3]. If your town's real property rate is higher than that, your car bill is figured at the cap.

Which Connecticut towns have the highest and lowest mill rates?

Hartford's 74.29 mills is nearly seven times Sharon's 10.60 ^[2]. That gap comes from what each town has to tax and what it has to spend. Hartford carries a large exempt property base (state buildings, hospitals, universities), a small grand list against a big budget, and heavy social service costs. Sharon, Salisbury, Greenwich, Cornwall, and Roxbury keep rates low because high property values throw off plenty of revenue at a low rate.

Here's what the extremes do in practice. A home assessed at $200,000 in Hartford pays $14,858 a year. The same assessed value in Salisbury pays $2,180. Those two owners could be neighbors across a town line.

The highest-rate towns for 2024-25 are Hartford (74.29), Waterbury (60.21), Hamden (55.48), Bridgeport (54.37), East Hartford (49.92), and New Britain (49.80). Mostly older industrial cities with shrunken commercial tax bases.

The lowest are Sharon (10.60), Salisbury (10.90), Cornwall (11.30), Norfolk (11.40), Roxbury (11.50), Warren (11.50), Washington (11.53), and Greenwich (11.868). Greenwich lands here despite being one of the richest towns in the country. The enormous grand list holds the rate down even though individual properties are worth a fortune.

A high mill rate doesn't mean your assessment is wrong. It does mean any error costs you more. So if you live in a high-rate town, check your assessed value carefully.

What is Meriden's mill rate and how does it compare to nearby towns?

Meriden's mill rate for 2024-25 is 40.86 mills ^[2]. That puts the city among the higher-rate towns in Connecticut, though well below the top. For a home assessed at $150,000 (about a $214,000 market-value home at the 70% ratio), the rate produces a bill near $6,129 a year.

Meriden's rate has moved around over the past decade as the city managed budget pressure. Meriden reassessed on the October 1, 2021 grand list, which reset many values and shifted plenty of bills up or down.

Here's how Meriden compares to its neighbors:

Town	2024-25 Mill Rate
Meriden	40.86
Wallingford	28.47
Cheshire	31.49
Berlin	31.08
Middletown	33.52
Southington	30.72
Durham	32.91

Wallingford, right across Meriden's northern line, charges about 30% less per dollar of assessed value. If you own in Meriden and your assessed value is inflated, the damage compounds at 40.86 mills. A $20,000 over-assessment costs you roughly $817 extra a year, before interest.

Meriden's assessor's office sits in City Hall at 142 East Main Street, Meriden, CT 06450, and the city posts the current mill rate on its website ^[4].

How do Connecticut mill rates get set each year?

Each spring, the town's board of finance or legislative body adopts a budget. The mill rate then comes from dividing the net revenue needed from property taxes by the total net taxable grand list, then multiplying by 1,000 ^[5].

Formula: Mill Rate = (Revenue Needed from Property Taxes / Net Grand List) x 1,000

The grand list is the total assessed value of all taxable property in town as of October 1 of the prior year. That date matters. Assessors finalize values as of October 1, and those values support the bills mailed the following July 1.

When a town revalues property (required at least every five years under CGS Section 12-62 ^[6]), the new assessments change the grand list. The town then adjusts the rate to hit roughly the same total revenue. In practice, the rate often drops after a revaluation when market values have risen. But individual bills can still go up or down, depending on how your property moved relative to the town average.

Motor vehicles get their own column in the grand list. Since fiscal year 2022-23, that rate has been capped at 32.46 mills statewide, no matter what the town charges on real property ^[3]. Towns above the cap get reimbursed by the state for the gap.

Does a high mill rate mean my property taxes are unfair?

No. The mill rate is a town-level policy number. Whether your bill is fair depends on one thing: whether your assessed value matches 70% of your property's fair market value as of October 1.

You can't appeal the mill rate. Elected officials set it, and changing it takes a political process, not a hearing. What you can appeal is your assessed value.

Here's the test. Pull recent sales of comparable homes in your neighborhood (the assessor's office or the town GIS map often lists sale prices). If similar homes sold for $300,000 and yours is assessed at $240,000, that's 80% of market value, not 70%. You're over-assessed by roughly $30,000. At Meriden's 40.86 mills, that error costs $1,226 a year.

Connecticut's appeal process starts with the local Board of Assessment Appeals (BAA). You have to file by February 20 of the year following the October 1 grand list date you're challenging ^[7]. Miss it and you lose the appeal for that year. If the BAA turns you down, you can take it to Superior Court.

If you'd rather run the appeal yourself instead of handing a contingency firm a cut of your savings, TaxFightBack's DIY appeal kit walks through the Connecticut process step by step: how to pull comparable sales, complete the BAA petition, and present your case.

How is my Connecticut property tax bill calculated from the mill rate?

Three steps.

Step 1: Find your assessed value. It's 70% of your property's appraised fair market value as of October 1 ^[1]. Your assessment notice or the town's online database shows the number.

Step 2: Divide by 1,000. This converts assessed value into the unit the mill rate uses.

Step 3: Multiply by the mill rate.

Example: assessed value $210,000, mill rate 33.52 (Middletown 2024-25). $210,000 / 1,000 = 210 210 x 33.52 = $7,039.20 a year.

Some towns also charge a separate fire district or sewer district tax on top of the municipal rate. These are usually small (1 to 5 mills) but they add up, and they should show as separate line items. If your bill runs higher than the math above, look for district levies.

Connecticut towns send real property bills in two installments, due July 1 and January 1, with a grace period that usually runs to August 1 and February 1. Late payments accrue interest at 1.5% per month (18% a year) under CGS Section 12-146 ^[8]. That rate is identical in every Connecticut town, so there's no shopping around for a cheaper late fee.

What is Connecticut's motor vehicle mill rate cap and how does it affect my bill?

Since fiscal year 2022-23, Connecticut has capped motor vehicle mill rates at 32.46 mills ^[3]. Before the cap, car owners in high-rate cities like Hartford and Waterbury paid vehicle taxes at the same rate as real property, which turned old cars into eye-watering bills.

The cap means a car registered in Hartford is taxed at 32.46 mills even though Hartford's real property rate is 74.29. The state makes Hartford whole for the lost revenue. Every town with a real property rate above 32.46 applies the cap to motor vehicles automatically. You don't file anything.

For towns below 32.46 mills, the cap changes nothing. Your car is taxed at the local rate, same as real property.

Motor vehicles are assessed at 70% of retail value using the October 1 State of Connecticut vehicle valuation list. If you think your car is over-valued, you can appeal to the BAA with documentation of its actual condition, mileage, or a lower private-market value. The BAA can cut the assessed value. It cannot cut the mill rate below the statewide number.

How often do Connecticut towns revalue property, and what happens to the mill rate?

Connecticut law requires a full revaluation at least every five years under CGS Section 12-62 ^[6]. Some towns run physical inspections. Others use statistical mass appraisal. Towns can also do interim adjustments in the years between.

When a revaluation lands, the grand list usually grows because market values have climbed. The town is then supposed to lower the rate so total revenue doesn't jump on its own. Towns keep the ability to raise the rate if the budget demands it.

Revaluation years breed confusion. Some owners see their assessed value rise faster than their neighbors' when the market moved unevenly. Others see it fall. Your bill can go up even when the rate drops, if your property was under-assessed before.

Appeals cluster right after a revaluation. If your new assessment looks wrong, you have until February 20 following the October 1 grand list date to file with the BAA ^[7]. That window is firm. The prior year's assessment is a separate appeal with its own deadline.

How do Connecticut mill rates compare to other states?

Connecticut rates look brutal on paper against states that quote their tax differently. A 30-mill rate here is 3%, but it applies only to 70% of market value, so the effective rate on market value is about 2.1%. That's the honest comparison number.

The Lincoln Institute of Land Policy's 50-State Property Tax Comparison Study (2023 edition) found Connecticut's effective property tax rate on owner-occupied housing ranked among the top 10 highest in the country, though the exact ranking shifts with the city size studied ^[9]. Hartford ranked near the top of large cities for effective tax burden relative to home value.

For context: New Jersey cities usually top these rankings (effective rates above 2.5% in many), followed by Illinois, Connecticut, and Wisconsin. Alabama, Arkansas, and Hawaii sit at the low end, under 0.5%.

What this means for you: your mill rate will always sound alarming to someone in Tennessee. What matters is whether your assessed value is accurate. A correct assessment at a high rate is a local policy fight. An inflated assessment at a high rate is a fixable legal problem.

Curious how CT's system stacks up against other appeal processes? See our guides on san diego property tax and los angeles county property tax, where California's Prop 13 creates very different math.

Can I use the mill rate to figure out if I should appeal my Connecticut assessment?

Yes, and it's exactly where you should start. The mill rate tells you what each dollar of over-assessment costs you per year. Work backward from there.

Ask first: what would my home sell for today? Pull recent comparable sales from the town assessor's database, the CT OPM data, or the usual real estate sites. Take your market estimate and multiply by 0.70 to get what your assessment should be.

Compare that to the actual assessed value on your tax bill or in the assessor's records. If your actual number is higher, you may have a case.

Dollar value of the error per year = (Over-assessed amount / 1,000) x Mill Rate.

In a high-rate town like Hamden (55.48) or West Hartford (42.23), even a $15,000 over-assessment costs you $832 or $633 a year. In a low-rate town like Darien (15.78), the same error costs $237. That doesn't mean you skip the appeal in Darien. But the math on hiring a contingency firm (which typically takes 30% to 50% of the first year's savings) looks very different.

For a lot of Connecticut homeowners, running the appeal yourself is the better deal. Our appeal process guides cover the general structure of a hearing, and the Connecticut-specific steps track the BAA petition process ^[7].

The TaxFightBack appeal kit is built for exactly this: you know you're over-assessed, you don't want to give away half the savings, and you want a clear checklist for the BAA hearing.

Where can I find the official mill rate for my Connecticut town?

Three reliable places, in order of authority:

1. The Connecticut Office of Policy and Management (OPM) publishes the annual Mill Rate Table for all 169 municipalities. It lives on portal.ct.gov under the OPM section, updated after towns certify their rates each spring ^[2]. This is the single best source.

2. Your town's tax collector or assessor website. Most Connecticut towns now post the current rate on the tax collector's page, often next to the payment portal. Search "[town name] CT tax collector mill rate."

3. Your tax bill itself. The bill shows the rate applied to your assessment. If the number on your bill doesn't match OPM's, call the tax collector. Clerical errors happen.

For Meriden, the city's tax collector page at meridenct.gov lists the current rate and payment schedule ^[4]. The assessor and tax collector both work out of City Hall.

Researching a town you might move to? Pull the rate from OPM, not from listing sites, which sometimes show stale numbers. Check whether a revaluation is coming, too, because a revaluation year can move your assessed value well off the prior owner's bill.

Frequently asked questions

What is Connecticut's highest mill rate in 2024?

Hartford holds Connecticut's highest mill rate for 2024-25 at 74.29 mills, per the CT Office of Policy and Management table. A property assessed at $100,000 there owes $7,429 a year. Waterbury is second at 60.21 mills, then Hamden at 55.48. These cities carry large exempt property bases and tight grand lists relative to their budgets.

What is the lowest mill rate in Connecticut?

Sharon has the lowest mill rate in Connecticut for 2024-25 at 10.60 mills, with Salisbury next at 10.90. These are small, wealthy Litchfield County towns where high property values throw off enough revenue at a low rate. Cornwall (11.30), Norfolk (11.40), Roxbury and Warren (both 11.50), and Washington (11.53) round out the bottom. Greenwich, despite its reputation, sits at 11.868.

What is Meriden CT's mill rate for 2024-25?

Meriden's mill rate for 2024-25 is 40.86 mills, per the CT OPM annual table. On a home assessed at $150,000 (about a $214,000 market-value property at the 70% ratio), that's an annual bill near $6,129. Meriden's neighbor Wallingford charges 28.47 mills, which makes the gap stark for owners near the town line.

How do I calculate my Connecticut property tax from the mill rate?

Multiply your assessed value by the mill rate, then divide by 1,000. Assessed value is 70% of appraised fair market value. Example: assessed value $180,000, mill rate 35.00: ($180,000 x 35.00) / 1,000 = $6,300. Check your bill for any fire district or sewer district levy, which can add 1 to 5 mills on top of the municipal rate.

Can I appeal my property tax if the mill rate is too high?

No. The mill rate is a legislative decision by the town council or board of finance, and the Board of Assessment Appeals can't touch it. What you can appeal is your assessed value. If your home is assessed above 70% of its fair market value, you have grounds to file a BAA appeal by February 20 of the year following the assessment date.

What is the motor vehicle mill rate cap in Connecticut?

Connecticut caps motor vehicle mill rates at 32.46 mills statewide, effective fiscal year 2022-23 under the state budget law. Towns with real property rates above that apply 32.46 to cars and get reimbursed by the state for the difference. Towns below the cap use their regular rate. The cap applies automatically, so there's nothing to file.

How often does Connecticut require towns to revalue property?

Connecticut General Statutes Section 12-62 requires a full revaluation at least every five years. Revaluations reset assessed values to reflect market conditions as of October 1. Afterward, towns adjust the mill rate to hold roughly the same total revenue, but individual bills can still rise or fall depending on how your property moved relative to the town average.

When is the deadline to appeal a Connecticut property tax assessment?

You must file a written appeal with the Board of Assessment Appeals by February 20 of the year following the October 1 assessment date you're challenging. For the October 1, 2024 grand list (which supports 2025-26 bills), the deadline is February 20, 2025. Miss it and you forfeit the appeal for that year. The BAA then schedules hearings in March.

Why do Connecticut mill rates vary so much between towns?

Each town sets its own budget and has a different grand list (total taxable assessed value). A town with a big commercial base or high-value homes generates more revenue per mill, so its rate stays low. Cities like Hartford and Waterbury carry large shares of exempt property (government, nonprofits, hospitals) and higher service costs, which drives rates up.

Are Connecticut mill rates the same for real property and motor vehicles?

Not always. Since 2022-23, motor vehicle rates are capped at 32.46 mills statewide, no matter the local real property rate. Many Connecticut towns also split their real property rate from the personal property (business equipment) rate. When you research a town, confirm whether the published rate covers real property, motor vehicles, or personal property, because they can differ.

Where does OPM publish the official Connecticut mill rate list?

The Connecticut Office of Policy and Management publishes the municipal mill rate table each year on portal.ct.gov. Search 'OPM mill rate' or go to the OPM section of the state website. They update the table each spring after towns adopt budgets. It's the authoritative source and covers all 169 municipalities.

How does Connecticut's effective property tax rate compare to other states?

Connecticut's effective rate on owner-occupied housing ranks among the top 10 highest in the country, per the Lincoln Institute of Land Policy's 50-State Property Tax Comparison Study. The 70% assessment ratio means you convert the mill rate to an effective rate (mill rate x 0.70 / 1,000) to compare fairly. Connecticut's effective rates run roughly 0.75% to 5% depending on the town.

What towns in Connecticut have mill rates over 40?

Based on 2024-25 OPM data, towns over 40 mills include Hartford (74.29), Waterbury (60.21), Hamden (55.48), Bridgeport (54.37), East Hartford (49.92), New Britain (49.80), Bloomfield (44.92), New Haven (43.88), Windham (42.72), West Hartford (42.23), and Meriden (40.86), among others. Most are older urban centers with large exempt property bases.

Do Connecticut towns publish their mill rates online?

Most do, on either the tax collector's page or the assessor's page. The most reliable single source for all 169 towns is the OPM mill rate table on portal.ct.gov. Some towns post rates on their finance department pages. For Meriden, the current rate is on the city's tax collector page at meridenct.gov.
