Connecticut has an effective property tax rate of 1.54%, one of the highest in the nation, ranking 3rd or 4th depending on the year. Unlike most states, Connecticut abolished county government in 1960 – all property taxes are levied by 169 independent cities and towns, producing mill rates that range from 23 mills in Danbury to nearly 69 mills in Hartford. On a $375,000 home, the typical Connecticut homeowner pays approximately $5,775 per year (est., Tax Foundation 2026 / U.S. Census ACS 2023).
Connecticut has an effective property tax rate of 1.54%, placing it among the top 4 most expensive states for property taxes nationally. What makes Connecticut uniquely challenging to navigate is its town-based system: county government was abolished in 1960, so each of the state’s 169 cities and towns independently sets its own mill rate and budget. A homeowner in Danbury pays roughly half the effective rate of a homeowner in Hartford or Waterbury, even though both homes sit within the same state and are subject to the same mandatory 70% assessment ratio (est., Tax Foundation 2026).
Connecticut Property Tax Rates and How Mill Rates Work
Connecticut property taxes are expressed in mills, where 1 mill equals $1 of tax per $1,000 of assessed value. Under Connecticut General Statutes Section 12-62a, all real property must be assessed at 70% of fair market value. A home worth $375,000 is therefore assessed at $262,500. Applying a 40-mill rate produces an annual tax of $10,500. The effective rate relative to market value is 40 mills x 0.70 = 2.80% of market value.
Each town’s mill rate is determined annually by dividing the total tax revenue required from property taxes by the town’s net taxable Grand List (total assessed value of all taxable property). Towns with large commercial tax bases (Stamford, Danbury) or high property values can fund services at lower mill rates. Poorer urban centers with smaller Grand Lists and greater service demands (Hartford, Waterbury, New Britain, Bridgeport) are forced to levy very high mill rates to fund the same level of services, producing effective rates 2 to 3 times higher than wealthier suburbs.
Hartford is a special case: under CGS Section 12-62n, Hartford is the only Connecticut municipality authorized to apply a split assessment ratio, taxing residential property at approximately 35% of market value (instead of 70%) while keeping commercial property at the standard 70%. Despite its 68.95 mill rate, Hartford residential owners pay an effective rate of approximately 2.53% rather than the 4.83% that would apply at the standard ratio.
Connecticut statewide effective rate. On a $375,000 home, expect approximately $5,775 per year at the statewide average. Urban centers like Waterbury (3.79%) and Bridgeport (3.04%) carry rates more than double the state average (est., Tax Foundation 2026).

Connecticut Property Tax Relief Programs and Exemptions
Connecticut does not offer a general homestead exemption that reduces assessed value for all primary residence owners. Relief is targeted through specific statutory programs. The most significant statewide relief program is the Elderly and Totally Disabled Tax Relief Circuit Breaker (CGS Section 12-170aa), which provides a graduated tax credit of 10% to 70% of the annual property tax bill. For the 2025 tax year (based on 2024 income), the maximum benefit is $1,250 for married couples and $1,000 for single filers. Income limits are $54,700 for married couples and $44,800 for single filers. Applications are filed biennially between February 1 and May 15 with the local assessor.
Veterans receive a mandatory $1,000 assessed value reduction under CGS Section 12-81(19). Low-income veterans may receive a total reduction of $3,000, and service-connected disabled veterans receive exemptions scaling from $1,500 (10-25% disability) up to $10,000 (loss of limb or blindness). Public Act 24-46 (effective October 1, 2024) granted a 100% full property tax exemption on the primary residence for veterans with a 100% permanent and total service-connected VA disability rating – the most significant veterans’ property tax change in Connecticut in decades.
Additionally, Connecticut provides a state income tax credit of up to $300 (CGS Section 12-704) for property taxes paid on a primary residence. While modest, this partially offsets the cost for homeowners who owe Connecticut income tax. Many municipalities also adopt local option relief programs under CGS Section 12-129n providing additional tax freezes or deferrals for elderly or disabled residents beyond the state minimum.
| Program / Exemption | Benefit | Who Qualifies | Filing Deadline |
|---|---|---|---|
| Elderly / Disabled Circuit Breaker (State) | 10% to 70% of tax bill; max $1,000 single / $1,250 married | Age 65+ or totally disabled; income below $44,800 (single) / $54,700 (married) for 2025 tax year | Biennially, Feb 1 to May 15 with local assessor |

| Local Option Elderly / Disabled Relief (CGS 12-129n) | Varies by municipality – additional tax freezes or deferrals | Elderly or disabled homeowners in participating municipalities | Contact your local assessor for deadlines |
Connecticut Property Tax Assessment System and Revaluation Cycle
Under CGS Section 12-62a, all Connecticut municipalities must assess real property at exactly 70% of fair market value. This is a mandatory statewide standard, unlike states such as Pennsylvania where each county sets its own ratio. The practical result is that a $400,000 home carries a $280,000 assessed value throughout Connecticut, regardless of whether you live in Greenwich or Bridgeport. The only exception is Hartford, which uses a lower residential assessment ratio of approximately 35% under CGS Section 12-62n.
Connecticut municipalities are required to conduct a revaluation (reassessment to current market values) at least every five years under CGS Section 12-62. Municipalities may use either a physical revaluation (full interior and exterior inspection) or a statistical revaluation (market analysis using comparable sales data). Following a revaluation, municipalities may phase in large assessment increases over up to five years under phase-in provisions authorized by Public Act 24-151, providing some protection against sudden, large tax bill jumps after a reassessment year.
Property owners who disagree with their assessment have a right of appeal. The first step is filing a written appeal with the town’s Board of Assessment Appeals (BAA) between February 1 and April 1 each year (or within 90 days of the mailing of the assessment change notice following a revaluation). If unsatisfied with the BAA decision, owners may appeal to the Connecticut Superior Court. The state’s Office of Policy and Management provides oversight and data on town Grand Lists and equalization.
| System Element | Rule | Impact on Homeowner |
|---|---|---|
| Assessment Ratio (Standard) | 70% of fair market value (CGS 12-62a), mandatory for all 169 towns | A $400,000 home is assessed at $280,000 everywhere in CT except Hartford |
| Assessment Ratio (Hartford Only) | Approx. 35% for residential under CGS 12-62n (split ratio) | Hartford’s 68.95 mill rate produces a 2.53% effective rate for residential owners, not 4.83% |
| Revaluation Frequency | At least every 5 years (CGS 12-62) | Large value increases can appear after a revaluation; phase-in provisions can soften the impact |
| Phase-In of Assessment Increases | Up to 5-year phase-in after revaluation (P.A. 24-151) | Limits sudden large tax bill jumps following reassessment in rapidly appreciating markets |
| Motor Vehicle Cap | 32.46 mill rate cap on motor vehicle taxes statewide (CGS 12-71e); state reimburses municipalities for excess | Auto property tax bills are capped regardless of your town’s mill rate |
| Appeal Deadline (BAA) | February 1 to April 1 (written appeal to Board of Assessment Appeals) | Annual opportunity to challenge assessed value if you believe your home is over-assessed |
| No County Tax Layer | County government abolished in 1960; all taxes are municipal | Your tax bill comes entirely from your town – no separate county levy |
Major Tax Districts and Town Variations in Connecticut
Connecticut’s 10 largest towns span effective rates from 1.63% in Danbury to 3.79% in Waterbury – a range of more than 2 percentage points within the same state. This dramatic variation is driven almost entirely by the ratio of a town’s service and school funding costs to its taxable Grand List. Affluent suburbs with large, high-value commercial and residential tax bases (Stamford, Norwalk, Danbury) generate the same or more tax revenue at lower mill rates. Legacy urban centers with smaller, lower-value Grand Lists, higher service demands, and significant tax-exempt properties (hospitals, universities, state buildings) face structurally higher mill rates regardless of political choices.
Some towns contain sub-districts (fire districts, lighting districts, sewer districts) that levy additional mill rates on top of the base town rate. For example, some areas of Norwalk are subject to secondary district levies that bring the total effective rate above the base 1.72% shown here. Always check with your local assessor or tax collector for the total combined mill rate applying to your specific parcel’s address.

Recent Connecticut Property Tax Law Changes and 2025-2026 Outlook
The most significant recent change is Public Act 24-46, signed in May 2024 and effective October 1, 2024. This law grants a 100% full property tax exemption on the primary residence (or one motor vehicle if no home is owned) for Connecticut veterans who carry a 100% permanent and total service-connected VA disability rating. This is the most expansive veterans’ property tax benefit enacted in Connecticut in decades and makes Connecticut one of only a handful of states offering full exemption at this threshold.
The motor vehicle property tax cap of 32.46 mills (CGS Section 12-71e) continues through FY 2025. The state reimburses municipalities for revenue lost because their mill rate exceeds this cap – a program that costs the state tens of millions of dollars annually but protects residents of high-mill-rate cities from disproportionate vehicle taxes. Any potential changes to this cap or state PILOT (Payment in Lieu of Taxes) programs for tax-exempt properties will significantly affect urban centers like Hartford, New Haven, and Bridgeport, where large non-profit and state property holdings suppress the Grand List.
Connecticut homeowners should note that the federal SALT deduction cap of $10,000 is particularly impactful in Connecticut. A homeowner paying $8,000 in property taxes plus Connecticut’s 6.99% top income tax rate faces a combined SALT burden well above the $10,000 federal cap, losing meaningful deductibility. This was especially impactful when the cap was enacted in 2018 and affected high-tax states like Connecticut disproportionately.
| Change | Effective Date | Key Impact | Who Benefits |
|---|---|---|---|
| P.A. 24-46: 100% Disabled Veteran Full Exemption | October 1, 2024 | Full property tax exemption on primary residence for 100% P&T disabled veterans | CT veterans with 100% permanent and total VA disability rating |
| Motor Vehicle Tax Cap Maintained at 32.46 Mills | FY 2023-25 (ongoing) | Motor vehicle property taxes capped; state reimburses high-mill-rate municipalities | All CT vehicle owners in high-tax towns |
| Assessment Phase-In Provisions (P.A. 24-151) | 2024 | Towns may phase in large post-revaluation assessment increases over up to 5 years | Homeowners in towns with recent revaluations showing large value jumps |
| Circuit Breaker Income Limits Increased | Annual CPI adjustment | 2025 income limits: $44,800 (single), $54,700 (married) – raised from prior year | Elderly and disabled homeowners near the income threshold |
| State Income Tax Credit (Up to $300) | Ongoing (CGS 12-704) | Up to $300 credit against CT income tax for property taxes paid on primary residence | CT homeowners who owe state income tax |
Disclaimer and Methodology
This calculator provides estimates for planning purposes only. Connecticut property tax bills depend on your specific town’s mill rate, your parcel’s assessed value (70% of fair market value as determined by your town assessor), any applicable exemptions, and any sub-district levies within your town. Connecticut property tax is entirely municipal – there is no county tax layer. Before purchasing property, always obtain the current tax bill from your town tax collector and confirm the current assessed value with the town assessor’s office.
What this calculator does not account for:
- Sub-municipal district levies (fire districts, lighting districts, water/sewer districts) that may add to the base town mill rate
- Hartford’s residential split assessment ratio (35% instead of 70% – already accounted for in Hartford’s dropdown rate)
- State Circuit Breaker credits, veteran exemptions, or local relief programs that reduce your taxable assessed value
- Phase-in provisions following a recent town revaluation that may temporarily lower your assessed value
How to get an accurate estimate:
- Look up your parcel on your town assessor’s website to find the current assessed value and any enrolled exemptions.
- Confirm the current mill rate with your town tax collector or on the CT Office of Policy and Management mill rate table.
- Multiply your assessed value by the mill rate and divide by 1,000 to get the annual tax. Subtract any exemption amounts first.
- Apply for the Elderly/Disabled Circuit Breaker or veterans’ exemption at your town assessor’s office before the May 15 biennial deadline if you qualify.
