NIM05719 - Class 1 NICs: Expenses and allowances: Mileage allowances: Rules before 6 April 2002: Calculating Class 1 NICs on mileage allowances - examples
This needs to be read in the context of the relevant NICS treatment that would have applied before 06 April 2002
Example 1 鈥� employer鈥檚 mileage rate is below the authorised rate
An employee is required to travel from Newcastle to York to attend a business meeting. The employee undertakes a round trip of 160 miles in his own car and is reimbursed by his employer at 30p a mile. The Inland Revenue鈥檚 Authorised Mileage Rate (AMR) for a car of the type used is 45p.
As the employer鈥檚 mileage rate is below the AMR, no NICs are due.
Example 2 鈥� employer鈥檚 mileage rate is above the authorised rate
An employee is required to travel from Newcastle to York to attend a business meeting. The employee undertakes a round trip of 160 miles in his own car and is reimbursed by his employer at 拢0.50 a mile. The AMR for a car of the type used is 拢0.45.
As the employer鈥檚 mileage rate is higher than the AMR, NICs are due on the excess. In this case NICs are due on 拢8.00 ((拢0.50 鈥� 拢0.45 = 拢0.05) x 160).
Example 3 鈥� employee travels in excess of 4,000 miles in the year.
An employee travels 500 business miles per month in his own car. The employer reimburses the employee 拢0.40 a mile. The AMR for the employee鈥檚 car is 拢0.45 for the first 4,000 miles and 拢0.25 for each mile travelled thereafter. By the end of month 9 the employee has undertaken 4,500 miles. The employer reimburses the employee 拢200.00 in month 9 for that month鈥檚 mileage (500 x 拢0.40).
As the employer鈥檚 mileage rate is no higher than the AMR for up to 4,000 miles, no NICs are due, see NIM05715. This is because, for NICs, the 鈥榰p to 4,000 mile鈥� rate is used irrespective of the number of business miles travelled.
