In the latest announcement from HMRC, there have been some changes to the AFR. 

Petrol and LPG vehicles for displacements up to 1400cc remain the same as the March 2016 AFR while diesel increases by one pence per mile (ppm). For vehicles between 1401cc and 1600cc, all fuel types have increased by one. Displacements between 1601 and 2000cc see petrol and LPG vehicles increase by one ppm but see diesel remain the same as before. Those vehicles with over 2000cc see petrol and diesel AFR increase by one but see LPG remain the same as March.

The AFR rates apply to all journeys on or after 1st June 2016 and for one month from the date of change, employers are able to choose to use either the previous or new current rates. Employers may therefore make or require supplementary payments if they so wish, but are under no obligation to do either.

Use of AFRs (Advisory Fuel Rates)

AFRs can be used to negotiate dispensations for mileage payments for business travel in company cars.

They are meant to reflect actual average fuel costs at the time they are set and save time for both employers and HMRC by setting out some figures that can be used in the majority of cases. They give employers more certainty about what the mileage rates that they choose to apply mean for tax and National Insurance contributions (NICs).

The rates only apply where employers:

  • reimburse employees for business travel in their company cars
  • or require employees to repay the cost of fuel used for private travel

The rates are advisory only.
