How is my P11d benefit in kind calculated for the fuel used by my car?

If your company pays for all your fuel used by your company car and you do not identify and pay back the personal mileage element, then there is a taxable fuel benefit as well as your car benefit.


Calculation Example

The car fuel benefit is based on a set figure £24,100 (2019/20) x CO2 emissions percentage for your company car. To calculate the CO2 emissions percentage use this table.

So in this example the car fuel benefit is £24,100 x 27% = £6,507 taxable benefit.

Therefore the director will pay personal tax on this amount, if he is higher rate tax payer, this will be £6,507 x 40% = £2,1602.80.

Best practice is for the director to ONLY claim his business mileage if he wishes to avoid this taxable benefit.
