  • Employees chargeable to tax

When an employer provides fuel for a company car, a taxable benefit is likely to arise. The taxable benefit is specifically known as a fuel benefit charge. The fuel benefit charge arises in addition to the company car taxable benefit.

The fuel benefit charge does not arise for employees who are provided with fuel in respect of a privately owned car. In those cases, the fuel provided or amounts reimbursed are chargeable either as earnings or under the benefits code, unless an exemption applies, eg where the payment is in the form of an approved mileage payment. See the Fuel related payments / mileage payments guidance note.

A fuel benefit charge arises no matter how the fuel for private use is provided, whether by way of a reimbursement of the costs or a provision of voucher of tokens, eg an employer could either reimburse an employee for all of his expenditure on fuel or provide the employee with a fuel card.
