Personalise Your Tax Calculation

Payments made to the employer for the private use of a company car are deducted from the car benefit charge after taking into account periods of unavailability. To qualify as a deduction:

  • There must be a requirement in the tax year to make payments as a condition of the car being available for private use.
  • The payments must be specifically for that private use.
  • The payments must actually have been made.
  • Payments for supplies or services, such as petrol or insurance, do not count.

For the 2021/22 tax year, the Government set figure for calculating the tax due on employer-provided free fuel for private use in a company car is £24,600. To calculate the tax, you need to know the Government set figure for fuel benefit tax, the car's combined fuel economy in mpg, BIK tax percentage, the price of fuel used and the driver's marginal tax rate.

Example: BMW 1 Series 118 Hatch 5Dr 2.0d 150 StopStart EU6 SE LCP Auto, 58.9 mpg, 29% BIK, 126 g/km CO2.

  • The 2021/22 Government scale charge is £24,600.
  • The 2021/22 tax percentage for this model is 29%.
  • £24,600 x 29% = £7,134 free fuel BIK value.
  • £7,134 equates to £2,854 annual tax liability for a 40% tax payer.
  • £2,854 will pay for 503 gallons of Diesel for a 40% tax payer (£2,854 divided by the price for a gallon of Diesel, £5.67 in April 2021).

Break even mileage is therefore 29,653 for a 40% tax payer (503 gallons x 58.9 mpg). For a 20% tax payer the break-even mileage is 14,826.

  • If the number of private miles you cover is less than the break-even mileage, consider paying for the fuel yourself as it will cost less than your tax liability.
  • If the number of private miles you cover is greater than the break-even mileage, you are better off paying the tax.
