These results, based on the data entered above, represent an indication of your income tax liability. The 4% supplement has been applied to cars powered by diesel unless they meet the Real Driving Emissions (“RDE”) Step 2 Standard or have been denoted as an alternative fuel qualifying vehicle that is not powered solely by diesel. The calculations do not take account of capital or private use contributions, or periods when your car may not be available.

The actual income tax you pay may differ from the results shown above and may only be determined when the P11d value of the car is confirmed immediately prior to its registration, the car’s CO₂ emissions are confirmed on its V5, and where appropriate its zero emission range is confirmed on its certificate of conformity.
