Connecticut consistently ranks among the states with the highest property taxes in the nation. With no county government layer, municipalities bear primary responsibility for funding local services, especially public education, through property tax revenue. As a result, effective property tax rates across Connecticut are significantly above the national average, and homeowners should plan carefully to manage this major expense.
Connecticut Property Tax Rates (2026)
| Metric | Rate / Amount |

| Median home value | ~$315,000 |
| Median annual property tax | ~$5,637 |
| Mill rate range (statewide) | ~11 to ~75 mills |
Connecticut uses a mill rate system, where one mill equals $1 of tax per $1,000 of assessed value. Properties are assessed at 70% of fair market value, and the mill rate is applied to this assessed value to determine the annual tax bill.

How Connecticut Property Tax Works
Assessment at 70% of Fair Market Value
Connecticut law requires all real property to be assessed at 70% of its fair market value. This assessment ratio is uniform statewide, though the fair market value determination is made locally by each municipality’s assessor. The assessed value multiplied by the local mill rate produces the annual property tax bill.
Revaluation Cycle
Connecticut mandates a property revaluation at least once every five years. Municipalities may also conduct physical reappraisals or statistical revaluations in between. After a revaluation, the municipality typically adjusts the mill rate to remain revenue-neutral, though governing bodies may choose to set a different rate following public hearings.
Motor Vehicle Property Tax
Connecticut is one of the few states that taxes motor vehicles as personal property. The mill rate applied to motor vehicles is capped at ~45 mills statewide. Vehicles are assessed at 70% of their average retail value as reported in the NADA guide, with the value declining each year based on a depreciation schedule.
Exemptions and Deductions
- Homeowners’ Tax Credit Program: Connecticut provides a property tax credit of up to ~$1,250 for qualifying homeowners aged 65 and older (or surviving spouses aged 50+) with income below ~$45,800 (single) or ~$55,950 (married).
- Veterans’ Exemption: Veterans with 90+ days of wartime service receive a basic exemption of ~$1,500 off assessed value. Disabled veterans may qualify for additional exemptions up to ~$3,000, and 100% disabled veterans may receive a full exemption.
- Disability Exemption: Totally disabled homeowners may receive a ~$1,000 reduction in assessed value if income requirements are met.
- Local Option Exemptions: Municipalities may adopt additional property tax relief programs, including tax deferral for elderly homeowners and abatements for specific property types.
- PA 490 (Farm, Forest, Open Space): Qualifying agricultural land, forestland, and open space may be assessed at use value rather than fair market value, significantly lowering the tax burden.
Comparison to Neighboring States
| State | Avg. Effective Rate | Median Tax Paid | Assessment Ratio |
|---|---|---|---|
| Connecticut | ~1.79% | ~$5,637 | 70% |
| New York | ~1.62% | ~$6,500 | Varies by locality |
| Massachusetts | ~1.15% | ~$5,500 | 100% |
| Rhode Island | ~1.40% | ~$4,200 | 100% |
| New Jersey | ~2.23% | ~$8,800 | Varies by county |
Connecticut’s effective rate places it above most New England neighbors but below New Jersey. However, because Connecticut’s median home values are lower than some neighboring areas, the dollar amount paid can vary significantly by municipality.
Tips for Managing Connecticut Property Taxes
- Review your assessment notice carefully after each revaluation year and compare the assessed value to recent comparable sales at the 70% ratio.
- File an appeal within the deadline — property owners generally have until February 20 following the assessment date (October 1 Grand List) to file with the local Board of Assessment Appeals.
- Apply for all available exemptions including the elderly homeowners’ credit, veterans’ exemption, and PA 490 classification if you own qualifying land.
- Consider the motor vehicle tax when purchasing vehicles, as Connecticut’s vehicle property tax can add ~$500 to ~$1,500 annually depending on the vehicle’s value and local mill rate.
- Compare mill rates across municipalities if you are relocating within Connecticut, as rates can differ by a factor of four or more between towns.
- Explore tax deferral programs if you are an elderly homeowner on a fixed income — some municipalities offer tax deferral with modest interest until the property is sold.
- Deduct property taxes on your federal return up to the ~$10,000 SALT cap if you itemize deductions. See the federal income tax guide for details.
