The short answer on Simsbury CT property taxes
Simsbury's current mill rate is approximately 30.58 mills. Properties are assessed at 70 percent of fair market value. On a home that sells for 600,000 dollars, the assessed value is 420,000 dollars and the estimated annual tax is approximately 12,844 dollars. Simsbury's mill rate is lower than Avon's 32.46 and slightly higher than Farmington's 27.36 and Canton's 27.87. It is meaningfully lower than West Hartford's mid-to-high 40s range, making Simsbury a strong value on property tax for buyers considering both markets.
How Property Taxes Work in Connecticut
Connecticut municipalities assess property at a set percentage of fair market value called the assessment ratio. Simsbury uses 70 percent. The assessed value — not the sale price — is what the mill rate is applied to. One mill equals one dollar of tax per 1,000 dollars of assessed value.
The formula: Sale Price × 0.70 = Assessed Value. Assessed Value × Mill Rate ÷ 1,000 = Annual Property Tax. A 750,000 dollar home in Simsbury has an assessed value of 525,000 dollars. At 30.58 mills: 525,000 × 30.58 ÷ 1,000 = approximately 16,055 dollars per year.

Simsbury vs. Valley Tax Comparison
Among the five Farmington Valley towns, Simsbury sits in the middle of the mill rate range. Granby carries the lowest rate at approximately 25.12 mills, followed by Farmington at 27.36 and Canton at 27.87. Simsbury's 30.58 is meaningfully lower than Avon's 32.46. For buyers comparing Simsbury and Avon on carrying costs, the tax difference on a 700,000 dollar home works out to approximately 1,300 dollars per year in Simsbury's favor — a real but not decisive figure over a standard holding period.
The comparison against Fairfield County is where Simsbury's tax picture becomes most compelling. A comparable home in Darien, Greenwich, or Westport typically carries a property tax burden two to three times higher than the same home in Simsbury. For buyers relocating from lower Fairfield County who are accustomed to those tax bills, the Simsbury number is often genuinely surprising in the best way.
When to Expect Reassessment
Connecticut requires full revaluation of all municipal property at least once every ten years, with interim revaluations every five years. After a revaluation, the mill rate is typically adjusted to prevent automatic revenue windfalls — the goal is tax neutrality across the revaluation. However, individual properties that appreciated significantly above town averages between valuations can see disproportionate increases in their tax bill. Buyers purchasing renovated or significantly improved properties should factor in the possibility that the next assessment will reflect the improved value more fully than the current assessed value does.
