NIM05703 - Class 1 NICs: Expenses and Allowances: Mileage allowances: Class of NICs due

To determine whether Class 1 NICs or Class 1A NICs are due on any form of assistance an employer provides in meeting the costs involved in using a privately owned car for business purposes, it is important to establish how the assistance is provided.

If an employer

  • reimburses an employee the costs of using their own car for business travel, either by way of a mileage allowance or by exact reimbursement
  • see NIM05708 for payments made before 6 April 2002
  • see NIM05815 and NIM05816 for payments made on or after 6 April 2002
  • provides fuel and meets other costs directly, for example by supplying fuel from the employer’s own fuel pump or by contracting direct with a garage for servicing and repairs, Class 1A NICs may be due, see NIM06050.
