SALT Deduction Cap 2026

$40,000 (OBBBA) — most CT homeowners can now fully deduct property taxes on federal return

Introduction

Connecticut has no statewide property tax rate. Instead, every one of CT's 169 towns and cities sets its own mill rate — dollars of tax per $1,000 of assessed value. The result is one of the widest property tax spreads in the United States: a $400,000 home in Hartford generates a $20,720 annual tax bill, while the same home in Greenwich costs just $3,080.

This guide explains how CT property tax is calculated, why rates vary so dramatically, the relief programs available to seniors and veterans, and how the One Big Beautiful Budget Act's raised SALT deduction cap changes the math for many Connecticut homeowners.

Section 01

How Connecticut Property Tax Works: Mill Rates and the 70% Assessment Ratio

Connecticut property tax has two moving parts: the **assessed value** of your property and the **mill rate** set by your town. **Step 1 — Assessed Value: 70% of Fair Market Value** State law (CGS §12-64) requires municipalities to assess real property at 70% of its estimated fair market value (FMV). This 70% figure is called the assessment ratio or assessment percentage. - Home market value: $400,000 - Assessed value (AV): $400,000 × 70% = **$280,000** The 70% ratio applies uniformly across the state. However, because towns revalue properties on a 5-year cycle, assessed values can lag significantly behind current market prices — particularly during hot real estate markets. **Step 2 — Mill Rate: Dollars per $1,000 of Assessed Value** Each town's **board of finance** sets a mill rate annually as part of the municipal budget process. One mill equals $1.00 of tax for each $1,000 of assessed value. Formula: > **Annual Property Tax = (Assessed Value ÷ 1,000) × Mill Rate** **Worked Examples at $400,000 FMV:** | Town | Mill Rate | Assessed Value | Annual Tax | |---|---|---|---| | Hartford | 74.29 | $280,000 | **$20,801** | | Waterbury | 60.21 | $280,000 | **$16,859** | | Bridgeport | 53.99 | $280,000 | **$15,117** | | New Haven | 43.88 | $280,000 | **$12,286** | | Stamford | 21.88 | $280,000 | **$6,126** | | Fairfield | 19.51 | $280,000 | **$5,463** | | Westport | 16.86 | $280,000 | **$4,721** | | Darien | 14.20 | $280,000 | **$3,976** | | Greenwich | 11.28 | $280,000 | **$3,158** | All at identical $400,000 FMV and the same 70% assessment ratio — yet the tax bill varies by nearly **$17,600 per year** depending solely on location. **The Grand List** Each October 1, the town assessor compiles the "grand list" — a record of all taxable property and their assessed values as of that date. The following fiscal year's mill rate is calculated by dividing the town's budgeted expenditures (minus other revenue) by the total grand list. Per CT OPM, the mill rates for FY 2025–2026 are based on the October 1, 2024 grand list. **Personal Property and Motor Vehicles** The same mill rate applies not just to real estate but also to personal property (business equipment) and motor vehicles, though the motor vehicle mill rate is statutorily capped at 32.46 mills (CGS §12-71e) to limit the burden on car owners in high-mill-rate cities.

Section 02

Why CT Property Taxes Are So High: The Structural Reason

Connecticut's high property taxes are not an accident — they are a direct consequence of how the state funds local services. **Municipal Self-Funding** Connecticut relies more heavily on local property taxes to fund municipal services than almost any other state. Each of CT's 169 municipalities is largely responsible for funding: - K–12 public education (the single largest cost) - Police and fire departments - Road maintenance and capital improvements - Libraries, parks, and social services - Debt service on municipal bonds Unlike states that fund schools primarily through a state income tax distributed centrally, Connecticut's education aid formula leaves most of the burden on local property taxpayers. The result: your school district's budget is almost entirely your tax bill. **The Education Spending Driver** Connecticut consistently ranks among the top 5 states in per-pupil education spending (~$22,000–$24,000/student). That spending is financed locally. A town like Westport, with high property values and a large grand list, can achieve a low mill rate while still spending heavily on schools. A city like Hartford, with lower property values and a smaller grand list, needs an extremely high mill rate to raise the same absolute dollars per pupil. **No Regional Revenue Sharing** Connecticut's municipalities compete independently for grand list growth (new development, commercial investment). There is no broad regional revenue-sharing mechanism that would allow property-rich suburbs to subsidize property-poor cities beyond the state's Education Cost Sharing (ECS) grants. When ECS grants fall short, cities raise mill rates. **High Public Sector Costs** Connecticut has some of the highest public sector wages, benefits, and pension obligations in the nation. Police, fire, and education employee compensation costs are borne primarily by local property taxpayers, driving mill rates upward even in years when budgets nominally stay flat. **Why This Will Not Change Quickly** Proposals to shift education funding from local property taxes to the state income tax have been introduced in the General Assembly repeatedly but have not passed. Until such a structural change occurs, Connecticut's property tax burden will remain among the highest in the US.

Section 03

Town-by-Town Comparison: Fairfield County Paradox and High-Mill Cities

The most striking fact about Connecticut property taxes is the simultaneous existence of the state's lowest AND some of the state's highest absolute tax bills — often within 30 miles of each other. **The Fairfield County Paradox** Fairfield County towns like Greenwich, Darien, Westport, and New Canaan have the state's lowest mill rates. But they also have the state's highest home values. The result is that absolute tax bills remain very high in dollar terms, even though the effective rate is relatively low. **Fairfield County Examples (FY 2025–26):** | Town | Mill Rate | Median Home Value | Estimated Annual Tax | |---|---|---|---| | Greenwich | ~11.28 | ~$1,700,000 | **~$13,430** | | Darien | ~14.20 | ~$1,500,000 | **~$14,910** | | Westport | ~16.86 | ~$1,400,000 | **~$16,521** | | New Canaan | ~17.10 | ~$1,350,000 | **~$16,157** | | Norwalk | ~23.16 | ~$575,000 | **~$9,320** | | Bridgeport | ~53.99 | ~$230,000 | **~$8,720** | An interesting result: a Bridgeport homeowner in a $230,000 house pays only slightly less in absolute property tax than a Norwalk homeowner in a $575,000 house — because Bridgeport's mill rate is more than twice as high. **High-Mill-Rate Cities: Hartford, Waterbury, and Bridgeport** Connecticut's three most financially stressed cities consistently carry the state's highest mill rates: **Hartford (~74 mills):** The state capital has the highest mill rate in Connecticut. A heavily commercial and institutional city (UConn Health, hospitals, and state buildings are largely tax-exempt), Hartford's taxable grand list is disproportionately small relative to its population and service demands. The result is crushing property tax rates on those properties that are taxable — primarily owner-occupied homes, rental properties, and small businesses. **Waterbury (~60 mills):** A former industrial city with a challenged economy, Waterbury has seen steady mill rate increases as grand list values have not kept pace with municipal budget growth. **Bridgeport (~54 mills):** Connecticut's largest city by population, Bridgeport has a large portion of tax-exempt properties (hospitals, nonprofit housing, government buildings) that reduce the taxable grand list. **Inner-Ring Suburbs: New Haven and Beyond** New Haven (~43 mills) faces similar structural issues: Yale University — the city's largest employer — is largely tax-exempt under nonprofit status, though it voluntarily contributes payments in lieu of taxes (PILOTs). Even with PILOTs, the taxable grand list is insufficient, keeping mill rates elevated. **Other Notable Towns (FY 2025–26 approximate):** | Town | Mill Rate | Notes | |---|---|---| | West Hartford | ~40.92 | Sought-after suburb, strong schools | | Hamden | ~55.48 | New Haven suburb, financially pressured | | East Hartford | ~49.92 | Hartford suburb | | Glastonbury | ~36.07 | Prosperous Hartford suburb | | Simsbury | ~31.93 | Sought-after Hartford suburb | | Stamford | ~21.88 | Financial services hub, large grand list | | Milford | ~29.67 | Coastal New Haven County | **Practical Implication for Buyers** When evaluating a home purchase in Connecticut, the sticker price is only part of the equation. A $400,000 home in Hamden carries a $15,534/year property tax bill versus $6,126 for the same value in Stamford — a $9,408 annual difference. Over a 30-year mortgage, that gap compounds to over $280,000 in additional property taxes (not counting future rate changes or appreciation).

Section 04

The 5-Year Revaluation Cycle and Assessment Shock

Connecticut requires each municipality to revalue all taxable property at least once every five years (CGS §12-62). This creates a risk that property owners often call **assessment shock** — a dramatic jump in assessed value and therefore property taxes, arriving all at once after years of no change. **How Revaluation Works** During a revaluation year, the town assessor (or a contracted appraisal firm) updates the estimated fair market value of every property in town as of October 1 of that year. The new assessed value equals 70% of the new FMV estimate. Between revaluation years, assessed values are generally static (apart from new construction or improvements requiring building permits). In a town that revalued in 2020 and is due to revalue in 2025, a homeowner who bought at $500,000 in 2020 might see their assessed value jump to reflect 2025 market values — potentially a 30–50% increase in assessed value in areas with strong appreciation. **The Mill Rate Offset (Partial)** When assessed values rise across the entire town, the mill rate typically drops proportionally — because the same budget dollars are now spread across a larger total grand list. In theory, the average homeowner should see minimal change. In practice, individual homeowners experience very different outcomes depending on whether their specific property appreciated faster or slower than the town average: - **Property appreciated faster than average:** Your tax bill rises - **Property appreciated slower than average:** Your tax bill falls - **Property appreciated at the average rate:** Minimal change **Recent Revaluation Impact** Many Connecticut towns that revalued in 2022–2023 saw dramatic FMV increases reflecting the post-pandemic housing surge. Some homeowners saw 40–70% increases in assessed value. Even with mill rate reductions, individual bills rose significantly for owners whose homes outperformed the local average. **Appealing Your Assessment** If you believe your property's new assessed value is incorrect, you have the right to appeal: 1. **Informal appeal with the assessor:** Request a review within 30–90 days of receiving your assessment notice. Bring comparable sales data showing your home's market value is lower than the assessment implies. 2. **Board of Assessment Appeals (BAA):** File a formal appeal with your town's BAA, typically between February 1 and March 20 following the revaluation. You must appear in person or via written statement. 3. **Superior Court:** If you are unsatisfied with the BAA ruling, you have 60 days to appeal to the Connecticut Superior Court. Appeals are most successful when you can demonstrate comparable sales — recent arm's-length transactions for similar properties — that imply a lower fair market value than the assessor used. **Practical Tip** If you purchased your home within the last 12 months before a revaluation, your purchase price is powerful evidence of fair market value. Assessors are generally reluctant to assess above a recent, documented purchase price.

Section 05

Property Tax Relief Programs: Circuit Breaker, Veterans, and Disability Exemptions

Connecticut offers several state-administered property tax relief programs for eligible homeowners. The most significant are the Circuit Breaker credit for elderly and disabled homeowners and various veteran exemptions. **1. Homeowners' Elderly/Disabled Circuit Breaker Tax Credit** This is Connecticut's primary property tax relief program for seniors and totally disabled persons. Administered by the CT Office of Policy and Management (CGS §§12-170aa, 12-170bb, 12-170cc), it provides a direct credit against property taxes owed — not just a deduction. **Eligibility:** - Age 65 or older, OR totally disabled (as defined by Social Security Administration) - Owner and occupant of the property as your primary residence - Annual income does not exceed the program's income limits **Income Limits and Maximum Credits (2025–26 benefit year):** | Filing Status | Income Limit | Maximum Credit | |---|---|---| | Single | $42,370 | $1,000 | | Married (or qualifying surviving spouse) | $51,690 | $1,250 | Credits are awarded on a graduated scale — households near the income limit receive lower credits than those with lower incomes. The full maximum credit applies to the lowest income tiers. **How to Apply:** File Form M-35H with your local Town Assessor's Office between **February 1 and May 15** of each year. The credit is applied directly to your property tax bill. Contact your assessor or the OPM Homeowner Info Line (860-418-6290) for the specific graduated schedule. **2. Homeowners' Elderly/Disabled Freeze Program** This older program, established in 1967, froze property taxes for qualifying homeowners at the benefit level from their qualifying year. **No new applicants have been accepted since the 1978 program year** (CGS §12-129b). It remains active only for long-standing grandfathered participants and is not available to new applicants. **3. Veteran Exemptions** Connecticut provides two tiers of property tax relief for veterans: **Basic Veteran's Exemption ($1,000):** - Provided by all Connecticut municipalities - Eligible: honorably discharged veterans who served at least 90 days during wartime (or during periods of armed hostilities), and surviving spouses - File DD-214 with the town land records before October 1 - Reduces assessed value by $1,000 (saving ~$27–$74 in taxes depending on local mill rate) **Additional Veteran's Tax Relief (up to $1,000 additional):** - State-administered; state reimburses municipalities - Income-qualified veterans receive up to an additional $1,000 reduction in assessed value - File Form M-59a biennially with the town assessor between February 1 and October 1 - Specific income limits apply (contact your assessor for current thresholds) **4. Disability Exemptions** Totally disabled homeowners who do not qualify for the veteran's exemption may be eligible for: - **Totally Disabled Tax Relief:** Same income thresholds and credit structure as the Circuit Breaker program - **Disability exemption under CGS §12-81:** Certain categories of disability may qualify for assessed value reductions independent of the Circuit Breaker **5. Other Local Programs** Many towns offer locally funded programs beyond the state requirements. West Hartford, Greenwich, and Stamford, for example, have historically offered supplemental tax deferral or credit programs for seniors above the state income limits. Check with your local assessor as these programs vary and change with municipal budgets. **How Much Can Relief Programs Save?** For a Hartford homeowner with a $150,000 assessed value and a 74-mill rate, the annual tax bill is $11,100. The Circuit Breaker credit of $1,000 (single) or $1,250 (married) reduces that to $10,100–$9,850 — meaningful but modest relative to the total burden. For lower-mill-rate towns, the credit covers a higher fraction of the total bill.

Section 06

Connecticut's Combined Tax Burden: Income Tax Plus Property Tax

What makes Connecticut distinctly expensive is not property tax alone — it is the combination of high property taxes AND a meaningful state income tax. CT is one of a small number of states that imposes both. **Connecticut State Income Tax Rates (2025 Tax Year)** From CT Form CT-1040 TCS (Rev. 12/25), Table B — Initial Tax Calculation (Single/MFS): | Connecticut Taxable Income | Rate | |---|---| | Up to $10,000 | 2.00% | | $10,001 – $50,000 | 4.50% | | $50,001 – $100,000 | 5.50% | | $100,001 – $200,000 | 6.00% | | $200,001 – $250,000 | 6.50% | | $250,001 – $500,000 | 6.90% | | Over $500,000 | 6.99% | For married filing jointly, brackets are doubled (e.g., 2% on first $20,000; 4.5% on $20,001–$100,000; etc.). Note: CT also has a phase-out of the 2% rate for higher earners (Table C Add-Back) and a Tax Recapture at certain income levels (Table D), which effectively raise marginal rates above the stated brackets for incomes in certain ranges. **CT Personal Exemption (Phases Out for Higher Earners)** Single filers get a $15,000 personal exemption on CT AGI up to $30,000, phasing to zero by $44,000. Married filing jointly: $24,000 exemption phases out between $48,000–$71,000. These exemptions reduce CT taxable income but disappear entirely for higher earners. **Combined Burden: A Real-World Example** Consider a married couple earning $180,000 owning a $600,000 home in West Hartford (mill rate ~41): - Assessed value: $600,000 × 70% = $420,000 - Property tax: $420,000 × (40.92/1,000) = **$17,186/year** - CT income tax (approximate, MFJ): On ~$180,000 CT AGI - 2% on $20,000 = $400 - 4.5% on $80,000 = $3,600 - 5.5% on $60,000 = $3,300 - 6% on $20,000 = $1,200 - Subtotal: ~$8,500 (before phase-out effects) - **Total CT state + local tax burden: ~$25,686/year** For context, the same couple in Florida (no income tax, ~1% property tax on $600k home = $6,000) would pay approximately **$6,000/year** in combined state and local taxes — a difference of nearly $20,000 per year. **Why Connecticut Residents Stay** Despite the tax burden, Connecticut retains residents through: - Proximity to New York City and Boston employment markets - Top-ranked public school systems in higher-income towns - High quality of life, coastal access, and natural beauty - Strong healthcare infrastructure - Established professional and social networks But the long-term trend of net domestic out-migration from Connecticut — particularly to Florida and the Carolinas — is partly driven by the cumulative income tax + property tax burden, especially for retirees on fixed incomes.

Section 07

SALT Deduction Update: How OBBBA's $40,000 Cap Changes the Math for CT Homeowners

The **One Big Beautiful Budget Act (OBBBA)**, signed in 2025, raised the federal State and Local Tax (SALT) deduction cap from $10,000 to **$40,000** per year beginning with the 2025 tax year. This is a significant change for Connecticut homeowners who itemize federal deductions. **What SALT Covers** The SALT deduction allows itemizing taxpayers to deduct state and local taxes paid, including: - Connecticut state income taxes paid - Connecticut local property taxes paid - (Cannot include both income and sales taxes — whichever is higher) For most CT homeowners, the combined state income tax + property tax substantially exceeds $40,000 only for very high earners or owners of very expensive properties. Most CT households will now be able to deduct their **full property tax bill** on their federal return. **Impact by Scenario:** | Scenario | Property Tax | CT Income Tax | Total SALT | Deductible (Old $10k cap) | Deductible (New $40k cap) | Federal Tax Savings* | |---|---|---|---|---|---|---| | Modest home, middle income | $8,000 | $7,000 | $15,000 | $10,000 | $15,000 | +$1,100 | | Mid-range home, upper-middle income | $14,000 | $12,000 | $26,000 | $10,000 | $26,000 | +$3,520 | | High-value home, high income | $20,000 | $18,000 | $38,000 | $10,000 | $38,000 | +$6,160 | | Very high-value home, very high income | $35,000 | $40,000 | $75,000 | $10,000 | $40,000 | +$6,600 | *Estimated at 22% federal bracket for middle scenarios, 32% for upper scenarios. **Who Benefits Most** - Homeowners in mid-range communities (Glastonbury, West Hartford, Simsbury) with property taxes of $10,000–$25,000 see the largest proportional benefit from the raised cap — their full bill now deductible - High-income Fairfield County homeowners still hit the $40,000 cap, particularly when adding CT income tax - Very high earners in Greenwich or Westport may still be limited by the cap but benefit more than under the old $10,000 limit **Important: Must Itemize** The SALT deduction only applies if you itemize federal deductions (Schedule A). The 2025 federal standard deduction is $15,000 (single) and $30,000 (MFJ). Homeowners with significant mortgage interest, charitable contributions, and property taxes often exceed the standard deduction and benefit from itemizing. **Connecticut's Workaround: The CT PTET** Connecticut was the first state to enact a Pass-Through Entity Tax (PTET) as a SALT workaround for business owners. Under this mechanism, business entities pay state tax at the entity level (which is fully deductible as a business expense, not subject to SALT caps), with owners receiving a CT income tax credit. With the $40,000 SALT cap now in place, the urgency of the PTET workaround is reduced for many — but it remains valuable for owners of very profitable pass-through businesses.

Section 08

Strategies to Manage Connecticut Property Tax Costs

Given Connecticut's high property tax environment, proactive planning can meaningfully reduce your tax burden. **1. File for Every Exemption You Qualify For** Do not leave money on the table: - **Seniors 65+:** File Form M-35H for the Circuit Breaker credit every February 1–May 15 - **Veterans:** File DD-214 and Form M-59a for exemptions and additional veteran's relief - **Totally disabled:** Apply for the disability exemption and Circuit Breaker equivalent - **Local programs:** Ask your assessor about any supplemental town programs beyond state requirements **2. Appeal Your Assessment After Revaluation** Revaluation years create the best opportunity to challenge your assessed value. Within 30–90 days of receiving your new assessment notice: - Gather recent arm's-length sales of comparable properties within the past 12 months - Document any condition issues (deferred maintenance, functional obsolescence, adverse location factors) that would reduce your home's market value - Request an informal review with the assessor first — many reductions are granted at this stage without a formal appeal - If unsuccessful, file a formal appeal with the Board of Assessment Appeals (BAA) by March 20 **3. Monitor Assessment Between Revaluation Years** Sometimes assessments change mid-cycle due to building permits for additions, pools, or new structures. If you made improvements that you believe were over-valued, you can still appeal. Also, if you purchased a home recently at a price below its assessed value (divided by 70% to get implied FMV), that purchase price is evidence for appeal. **4. Consider Location When Buying** If you have flexibility in where to live within a commuting radius, mill rate differences are enormous: - Choosing Stamford (~22 mills) over Bridgeport (~54 mills) on a $400,000 home saves ~$8,990/year - Choosing Glastonbury (~36 mills) over West Hartford (~41 mills) on a $500,000 home saves ~$1,750/year Over a 30-year mortgage, these differences compound substantially. Build the property tax cost into your affordability calculation before making an offer. **5. Capitalize on the $40,000 SALT Cap** If you itemize federal deductions, ensure your tax preparer is capturing the full property tax deduction now available under OBBBA. Review whether you should be itemizing even if you previously took the standard deduction — the math may now favor itemizing for many CT homeowners. **6. For Business Owners: Use the CT PTET** If you own a pass-through business (S-corp, partnership, LLC), consult a CT tax professional about the Pass-Through Entity Tax. Even with the raised SALT cap, high earners with significant business income may benefit from the PTET structure. **7. Plan for Retirement in Connecticut** Retired homeowners in Connecticut face a compounding problem: fixed income + rising property taxes + CT income tax on pensions and Social Security (partially taxable above certain thresholds). Options: - Apply for Circuit Breaker credit as soon as you turn 65 - Downsize to a lower-assessed property in a lower-mill-rate town - Consider Connecticut's property tax deferral program (available in some towns, not state-wide) - Model the total tax burden of staying in CT versus relocating to a lower-tax state

FAQ

Frequently Asked Questions

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

A mill rate is the amount of tax levied per $1,000 of assessed property value. Connecticut has no statewide property tax; each of its 169 towns sets its own mill rate annually. One mill equals $1.00 of tax per $1,000 of assessed value. To calculate your bill: multiply your property's assessed value (70% of fair market value) by the mill rate, then divide by 1,000. Example: a $400,000 home in a town with a 40 mill rate has an assessed value of $280,000 and pays $280,000 × 40 ÷ 1,000 = $11,200/year in property tax.

What is Connecticut's property tax assessment ratio?

Connecticut law (CGS §12-64) requires municipalities to assess real property at 70% of its estimated fair market value. This means if your home's market value is $500,000, its assessed value for property tax purposes is $500,000 × 70% = $350,000. The mill rate is then applied to this $350,000 assessed value, not the full market value. All Connecticut towns use this 70% ratio.

Why is Hartford's property tax rate so much higher than Greenwich's?

Hartford's mill rate (~74) is roughly 6.5 times Greenwich's (~11) because of fundamental differences in their tax bases and budget demands. Hartford has a large percentage of tax-exempt properties (state government buildings, hospitals, nonprofits) that reduce its taxable grand list, while still needing to fund city services for a large population. Greenwich has an enormous grand list driven by very high home values and significant commercial activity, allowing it to raise the same absolute dollars with a much lower rate. Additionally, Hartford has higher service costs relative to its tax base, particularly for schools.

How does the Connecticut Circuit Breaker property tax credit work?

The Connecticut Homeowners' Elderly/Disabled Circuit Breaker provides a direct credit against property taxes for homeowners age 65+ or totally disabled. The credit is up to $1,000 for single applicants and $1,250 for married applicants, awarded on a graduated income scale — lower incomes receive higher credits. Income must not exceed $42,370 (single) or $51,690 (married). Apply using Form M-35H with your local Town Assessor's Office between February 1 and May 15 each year. The credit is applied directly to reduce your tax bill.

How often do Connecticut towns revalue properties, and what is assessment shock?

Connecticut requires towns to revalue all taxable property at least every five years (CGS §12-62). Assessment shock occurs when a revaluation year follows a period of rapid home price appreciation: the assessed value — and therefore the tax bill — jumps dramatically all at once after years of being frozen. Towns are required to notify property owners of their new assessed values, and homeowners have the right to appeal to the Board of Assessment Appeals (BAA) between February 1 and March 20 following a revaluation year.

Can I deduct my Connecticut property taxes on my federal return in 2026?

Yes, and the limit is significantly higher than before. The One Big Beautiful Budget Act (OBBBA) raised the federal SALT (State and Local Tax) deduction cap from $10,000 to $40,000 per year beginning in 2025. Most Connecticut homeowners — whose property tax alone often ranges from $8,000 to $25,000 — can now deduct their full property tax bill on their federal return when they itemize deductions on Schedule A. Very high earners in expensive towns may still be limited by the $40,000 cap once CT income taxes are added to the calculation.

Which Connecticut towns have the highest and lowest property tax rates?

As of FY 2025–26, Connecticut's highest mill rates are concentrated in its financially challenged cities: Hartford (~74 mills), Waterbury (~60 mills), Hamden (~55 mills), and Bridgeport (~54 mills). The lowest mill rates are in wealthy Fairfield County towns: Greenwich (~11 mills), Darien (~14 mills), and Westport (~17 mills). The statewide range is extraordinary — a factor of roughly 6.5x between highest and lowest — reflecting dramatic differences in property wealth per resident and municipal service demands.

Does Connecticut have a property tax exemption for veterans?

Yes. Connecticut provides a basic $1,000 property tax exemption (reducing assessed value by $1,000) for honorably discharged veterans who served at least 90 days during wartime or armed hostilities. This requires filing your DD-214 with the town's land records before October 1. Additionally, income-qualified veterans may receive up to $1,000 more through the state-administered Additional Veterans Tax Relief Program by filing Form M-59a biennially. Contact your local town assessor for current income thresholds and deadlines.

Is there a property tax freeze for seniors in Connecticut?

The original Connecticut Homeowners' Elderly/Disabled Freeze Program (CGS §12-129b) froze property taxes for eligible seniors at their qualifying year's level. However, this program has been closed to new applicants since 1978 and is only maintained for grandfathered participants. New senior homeowners cannot enroll in the freeze program. The available relief today is the Circuit Breaker credit (up to $1,250 for married households) for those meeting income eligibility requirements, and some towns offer locally funded supplemental programs.

How does Connecticut's property tax compare to neighboring states?

Connecticut has the 3rd highest effective property tax rate in the United States at ~1.54% of home value (Tax Foundation, 2026 edition, 2024 ACS basis), exceeded only by New Jersey and Illinois (tied for 1st at ~1.88%). Within New England specifically, Connecticut has the highest effective property tax rate — narrowly ahead of Vermont (~1.51%) and New Hampshire (~1.50%). This compares to: New York ~1.54%, Rhode Island ~1.40%, Massachusetts ~1.12%, and the national average of ~1.07%. What makes Connecticut particularly burdensome is the combination of high property taxes AND a 2–6.99% state income tax. By contrast, Florida has no income tax and a much lower property tax rate (~0.86%), making the combined CT-to-FL tax difference often $15,000–$30,000/year for a middle-to-upper-income homeowner.
