This system changed on 6th April 2002. The previous system was based on a mileage system. Responding to the environmental concerns about the ozone layer, and global warming, governments worldwide committed to reduce the output of greenhouse gases. This includes reducing Co2 emissions. The government began this process by providing a financial incentive to switch to cleaner cars by lowering vehicle excise duty on low emission cars.
The charge for benefit in kind taxation is based on graduated percentages based on Co2 emissions starting from 15% to 35% of the cars P11d price (emissions bands are in increments of 5g/km). Diesel cars have a flat 3% penalty which needs to be added onto the percentage relating to the co2 emissions.
The calculation is as follows to find the monthly cost:-
% relating to the Co2 emissions x P11d value x 22% or 40% personal tax liability 12 months
