The short answer on Avon CT property taxes
Avon's current mill rate is approximately 31.80 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 13,356 dollars. Avon's mill rate is the second lowest of the five Valley towns, higher only than Farmington and meaningfully lower than Granby, Simsbury, and Canton. The tax obligation is one of several carrying costs buyers should calculate before making an offer.
How Connecticut Property Taxes Work
Connecticut municipalities assess property at a fixed percentage of fair market value called the assessment ratio. In Avon, that ratio is 70 percent. The assessed value — not the sale price — is what the mill rate is applied to. The mill rate is expressed as a dollar amount per 1,000 dollars of assessed value.
The formula is straightforward: multiply the sale price by 0.70 to get the assessed value, then multiply the assessed value by the mill rate and divide by 1,000 to get the annual property tax. A sale price of 800,000 dollars produces an assessed value of 560,000 dollars, which at 31.80 mills generates an annual tax bill of approximately 17,808 dollars.

Avon Mill Rate vs. Other Farmington Valley Towns
Avon's mill rate of approximately 31.80 mills is the second lowest in the Farmington Valley, behind only Farmington at 27.36. Granby follows at 34.21, Simsbury at 35.00, and Canton carries the Valley's highest rate at 35.11. West Hartford, which competes with the Valley for some buyer segments, carries a significantly higher mill rate typically in the mid-to-high 40s.
The practical implication for buyers: a home of identical sale price in Avon will carry a lower annual tax bill than the same home in Granby, Simsbury, or Canton, and a higher bill than the same home in Farmington. Avon's relatively low rate for a town of its price tier is a genuine, underappreciated part of its value proposition.
When Property Is Reassessed in Avon
Connecticut law requires municipalities to conduct a general revaluation of all real property at least once every ten years, with interim adjustments every five years. Avon's most recent revaluation affects all property in town uniformly. After a revaluation, the mill rate is typically adjusted to prevent a windfall tax increase — reassessment changes the assessed value, and the mill rate is recalibrated accordingly. However, individual properties that have improved significantly since the last assessment may see disproportionate increases. Buyers purchasing a recently renovated home should be aware that the post-purchase assessment may reflect the improvement value more fully than the previous assessment did.
Other Annual Carrying Costs to Factor In
Property tax is the largest ongoing carrying cost for most Avon homeowners, but it is not the only one. Homeowner's insurance on a 700,000 dollar home in Connecticut typically runs 2,500 to 4,500 dollars annually depending on the age of the home, construction type, and coverage level. Homes with oil heat, older electrical systems, or on private septic and well will carry additional annual service and maintenance budgets. Buyers should build out a full annual cost picture before calculating affordability on any specific property.
