NI relief for Relevant Motoring Expenses (RME)

Use this tool to work out how much of each RME payment can be treated as free of employee National Insurance based on HMRC's approved mileage allowance payments (AMAP).

For each employee the NI free RME is the lower of the RME amount and (Paid miles × HMRC AMAP rate) minus (Paid miles × your mileage rate). Any remaining RME is treated as NIable pay.
