Connecticut Car Taxes Due Monday, Affecting Vehicle Owners
Connecticut car taxes are due on Monday, August 3, 2026. The taxes, typically due on July 1, have a 30-day grace period due to state law, which accounts for the late mailing of bills by many cities and towns. This year, since August 1 falls on a Saturday, the deadline is extended to the next business day. Taxpayers who miss this deadline will incur interest on their outstanding taxes. Additionally, all taxes must be paid in full for the Department of Motor Vehicles (DMV) to renew existing registrations or issue new ones.
