Mileage payments: two schemes  

There are two schemes for tax and NICs on payments to employees for mileage payments:

The two systems are aligned as far as possible, but there are some differences between them and they are explained in this guidance.

For tax: mileage allowance payments

Mileage allowance payments are payments that:

For NICs: relevant motoring expenditure

Relevant motoring expenditure:

  • includes the aggregate of all motoring expenses paid to, or on behalf of, an employee
  • in connection with the use of a privately owned vehicle
  • for business travel.

Relevant motoring expenditure is wider in scope than mileage allowance payments for tax.

Exemptions

Under the two systems mileage payments up to a statutory limit can be:

  • exempt from tax and
  • disregarded from earnings for NICs purposes.

We have prepared a simple checklist that you can use to make payments with no tax or NICs liability.
