Class 1 NICs: Expenses and allowances: Motoring expenses (including mileage allowances) paid on or after 6.4.02: Calculating the amount liable for Class 1 NICs
How to calculate the amount of motoring expenses, paid to employees using their owncar for business travel, to include in gross pay for Class 1 NICs applies from 6April 2002
To calculate the Class 1 NICs due on the motoring expenses as described at NIM05815 it is necessary to follow the steps below.
Identify the total amount of any relevant motoring expenditure (RME) paid to anemployee by an employer within an earnings period. RME incorporates all motoring expensespaid for the use of a privately owned car.
See NIM05815 for a more detailed explanation of what RME is.
Identify the maximum amount (the qualifying amount (QA)) the employer may pay free fromNICs liability. Calculate the QA by multiplying the relevant approved mileage rate by thetotal of
- the number of business miles for which payment is being made; and
- the number of business miles travelled, if any, since the last payment of motoring expenses was made but for which no payment is has been, or is to be, made.
See NIM05830 for a more detailed explanation about the QA.
Calculate if the RME exceeds QA.
If the RME exceeds QA, add the excess RME to other earnings paid in the same pay periodas the RME. Calculate Class 1 NICs due as normal.
If the RME is equal to or less than the QA, all the RME is disregarded from earnings. Anyunused QA cannot be carried forward to use in a later earnings period.
