Find the CO2 figure
Use the official CO2 figure for the car, usually shown in the V5C logbook or vehicle details. The calculator needs this value in g/km.
CO2-based VED bands
Car tax bands for 2001 to 2017 cars
Cars first registered from 1 March 2001 to 31 March 2017 normally use CO2-based VED bands. The higher the official CO2 figure in g/km, the higher the annual tax band for the 2026/27 tax year.

EVs are treated differently
Legacy zero-emission cars in this date range pay £20 in 2026/27, not the post-2017 £200 standard rate.
Newer cars use another system
Cars first registered from 1 April 2017 normally use the post-2017 standard-rate system after the first licence.
