HMRC advisory fuel rates for company car users from 1 September

HMRC has published the latest advisory fuel rates (AFR) for company car users, effective from 1 September 2018 introducing a 4p advisory electricity rate for fully electric cars

The advisory electricity rate for fully electric cars is 4p per mile. Electricity is not a fuel for car fuel benefit purposes.

The advisory fuel rates apply from 1 September 2018 and have slightly increased on the previous quarter rates, for petrol cars with engine of 2000cc or less and diesel cars with an engine size from 1601cc to 2000cc. The previous rates can be used for up to one month from the date the new rates apply.

The rates only apply in the following circumstances:

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

These rates cannot be used in any other circumstances. If the rates are used, it is not necessary to apply for a dispensation to cover the payments made.

When employees are reimbursed for business travel in their company cars, HMRC will accept there is no taxable profit and no Class 1A national Insurance to pay.
