Vehicle Excise Duty
The changes announced by the Chancellor in the 2015 budget set out that Vehicle Excise Duty (VED) will change for registered vehicles from 1 April 2017. The first vehicle licence will be calculated on the vehicle’s CO2 emissions.
All vehicles registered before this date will not be affected.
Vehicles registered on or after 1 April 2017
For all vehicles first registered on or after 1 April 2017, the amount you pay for the first 12 months is based on CO2 emissions.
