Car tax and ULEZ for a 2016 car
A car first registered in the UK in 2016 was issued a 65 (January–February), 16 (March–August) or 66 (September–December) plate, unless it was registered in Northern Ireland (no age identifier) or has since moved to a private plate. An imported one is plated when first registered here, so its plate can be newer than its first-use year. 16 plates
A 2016 car is taxed by its CO2 emissions band (A to M), shown on the V5C logbook. [2] Car tax calculator for a 2016 car
For the London ULEZ, a 2016 petrol usually meets Euro 4, and a 2016 diesel usually meets Euro 6. The Euro standard of the car decides, not the year alone. [3] ULEZ checker
