Does you employer still pay for your private fuel

As we are approaching the end of yet another tax year, it is worth repeating our suggestion that highlights the cash benefit to company car drivers and their employers, of reimbursing the cost of fuel provided for private motoring. The rates have been updated for 2017-18.

Since the tax on private fuel provided with company cars is so high, many employers have an arrangement whereby they no longer pay for private fuel. In many cases this means that the employee must reimburse the employer for private fuel included in petrol bills paid by the employer.

Consider the following example for 2017-18:

If your private mileage is currently 560 miles a month, and you drive a 1900cc diesel engine car, the rate per mile to cover fuel charges as quoted in the latest rates published by HMRC is 11p per mile. Accordingly, you should repay £61.60 a month to your employer.

Based on the above example, if the vehicle’s list price when new was £25,000, and the car benefit charge rate was 28% (based on a 130g/km CO2 rating) the benefit in kind charge for the year would be £7,000. With no repayment of private fuel, there would also be a £6,328 car fuel charge. Both these amounts would be added to your taxable income for the year. If you were a higher rate tax payer the car fuel charge would cost you £2,513.20 a year in additional tax (£6,328 x 40%). This amounts to £210.93 per month.

If your actual private mileage proved, on average, to be 560 miles a month, you would therefore save £149.33 per month (£210.93 – £61.60).

Employers will also benefit as they will no longer be subject to a National Insurance charge on the amount of the car fuel benefit. In the above example, it would reduce NIC costs by £873.26 (£6,328 x 13.8%).

It is worth crunching the numbers. Obviously, the lower your private mileage, the more likely a repayment system will save you money, but you will need to act before the 5 April 2018.
