SE31860 - Travel expenses: general - employees using own car for work - an alternative to the statutory basis - using the Inland Revenue's authorised mileage rates to calculate relief

Important note:

From 2002/03 the rules described below have changed. There is a new statutory mileage allowance relief rate that is used to calculate tax relief that employees can get for using their own vehicles for work. Employees are no longer entitled to deduct actual costs (the exact method) or to use the non-statutory authorised mileage rates (the simple method). There is detailed guidance on the new scheme at SE31330 onwards.

2001/02 and earlier

From 1996-97 onwards employees have been able to use an alternative to the strict statutory method (see SE31845 onwards) when calculating the amount of their allowable business motoring expenses.

They can use the Inland Revenue authorised mileage rates appropriate to their particular car to calculate the profit arising from motor mileage allowances received, or as the basis for a net deduction.

This applies irrespective of the method which the employer is using to report motor mileage allowances to the Inland Revenue (see SE30200 onwards). So the employee can use the Inland Revenue authorised mileage rates to calculate the profit or net deduction position on his or her mileage allowances if

  • the employer reports gross mileage allowances on form P11D, or
  • the employer has a dispensation, or
  • the employer uses the Fixed Profit Car Scheme to report profits.

If the employer uses the Car Allowances Enhanced Reporting Scheme to report profits or net deductions (as appropriate), there should be no point in the employee making his or her own claim using the Inland Revenue authorised mileage rates. This is because an employer who uses the Car Allowances Enhanced Reporting Scheme should be calculating the same profit or net deduction figure as the employee would by using the Inland Revenue authorised mileage rates.

Employees always have the right to submit a statutory Section 198 and capital allowances computation if they prefer.

Details of the amounts of the Inland Revenue`s authorised mileage rates can be found as follows:

1996/97 – SE31895

1997/98 to 2000/01 inclusive – SE31900.
