IM06053 Class 1 NICs: Expenses and Allowances: Fuel: Liability for NICs on fuel

General liability for NICs

NIM06052 lists the different methods by which an employer may provide fuel to hisemployees.

Liability for NICs on fuel will depend upon

  • the action taken by the employee prior to the purchase of the fuel and
  • the arrangements that an employer has put in place to allow an employee to purchase the fuel on his behalf
  • the method of provision of the fuel.

The general rule about NICs liability is that if an employer pays for fuel used by hisemployees and

  • the fuel is used for private mileage or
  • the payment the employee receives exceeds the actual cost of the business expense incurred

a NICs liability will arise.

Payments made before 6 April 2002 - Liability for Class 1 NICs

Where the cost of the fuel is met by the employer

  • reimbursing the employee’s fuel bills
  • paying a cash allowance
  • paying a round sum allowance
  • paying a mileage rate
  • providing a non-cash voucher for fuel
  • supplying a fuel agency card or credit card to allow the employee to purchase fuel where the employee is not acting on the employer’s behalf when purchasing fuel (see NIM06054)
  • allowing an employee to charge the fuel to an employer’s garage account where the employee is not acting on the employer’s behalf when purchasing fuel (see NIM06054)

the full cost of all private fuel and any amount which exceeds the actual businessexpenses of using the car for business travel, must be added to any other earnings paid inthe same earnings period when calculating Class 1 NICs liability.

For guidance on:

  • identifying business expenses, see NIM05020
  • acceptable mileage rates, see NIM05700
  • a non-cash voucher for fuel which can be disregarded for Class 1 NICs purposes, see NIM02416.

Liability for Class 1A NICs

Where the employer provides fuel by means of a payment or benefit in kind, for example
