The short answer: Granby sits in the middle of the Valley's tax range
At 34.21 mills, Granby's annual tax bill on a 500,000 dollar home runs approximately 11,974 dollars. That is about 844 dollars more per year than the equivalent Avon home, but roughly 276 dollars less than Simsbury and 314 dollars less than Canton. Granby is not the Valley's tax bargain the way Avon and Farmington are, but it carries a real, durable edge over Simsbury and Canton, the two towns most buyers compare it against directly. Combined with Granby's larger average lot sizes, the total cost-per-acre picture remains compelling for land-focused buyers.
How Connecticut Property Taxes Work
Connecticut municipalities assess property at 70 percent of fair market value in Granby. The assessed value is multiplied by the mill rate and divided by 1,000. Formula: Sale Price × 0.70 = Assessed Value. Assessed Value × 34.21 ÷ 1,000 = Annual Tax. A 600,000 dollar Granby home has an assessed value of 420,000 dollars. At 34.21 mills the annual tax is approximately 14,368 dollars.

Ten-Year Perspective
A Granby buyer on a 500,000 dollar home pays approximately 844 dollars more annually than the equivalent Avon purchase, but saves roughly 276 dollars a year versus Simsbury and 314 dollars a year versus Canton. Over ten years, the Granby-versus-Canton tax gap alone compounds to a little over 3,000 dollars. Granby's financial case rests primarily on land value, not on being the Valley's lowest tax rate: more acreage per dollar than Avon, Simsbury, or Canton, at a tax rate that is a modest but real improvement over the two towns closest to it in price.
