About Property Taxes in Connecticut
Connecticut property taxes are administered entirely at the town and city level — the state has no counties with governmental functions. Each of Connecticut's 169 municipalities has its own assessor who determines property values and its own mill rate. This means rates and policies vary significantly from town to town. Property is assessed at 70% of fair market value (this percentage is set by state law). Grand Lists (the official assessment rolls) are updated annually and full revaluations are conducted at least every five years. Connecticut consistently ranks among the states with the highest property tax burdens relative to home values.
Payment & Assessment
Payment schedules vary by town. Most Connecticut municipalities bill property taxes semi-annually: First installment: Due July 1 Second installment: Due January 1 Some municipalities bill quarterly. A grace period of 30 days typically applies, making the effective due dates August 1 and February 1 before interest begins. Late interest: 1.5% per month (18% annually) on unpaid balances, with a minimum of $2.00. Most towns offer online payment through their municipal website or a payment portal. Contact your town's tax collector for available payment methods.
