SE31905 - Travel expenses: general - employees using own car for work - calculation of allowable expenses - statutory basis - example

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

Employee buys own car for £6,000 and starts using it for business travel. In 99/2000 the employee travels 10,000 miles in the car. 2,500 of these miles count as business travel for tax purposes. The employee receives from the employer a mileage allowance of 30p a mile for all business travel.

Step 1

Total mileage allowances received
2,500 miles at 30p a mile£750(A)


Step 2

Calculate the total motoring costs for the year as follows
Insurance£400
Road fund licence£140
Fuel and oil£1,000
Servicing and repairs£300
Capital allowances for the year£1,500
Total motoring costs for the year£3,340(B)


Step 3

Business miles travelled2,500(C)
Total miles travelled10,000(D)
Proportion of motoring costs relating to business travel for the year
2,500(C)/ 10,000(D) x 3,340(B)£835(E)


Step 4

Difference between total mileage allowances received (A) and business proportion of motoring costs (E)£85

In this example as business proportion of motoring costs (E) is greater than total mileage allowances received (A), the employee can claim relief on the difference of £85 against earnings of the relevant employment.

If the total mileage allowances received (A) had been £835 and the business proportion of motoring costs (E) had been £750, the employee would have been taxable under Schedule E on the mileage profit of £85.
