Please see at the HMRC link below the company car fuel advisory rates to be used as a guidance on the reimbursement of employees for business fuel.
The advisory fuel rates apply from 1 December 2019 have decreased by 1p per mile for vehicles under 1600cc reflecting cuts in diesel prices over the last quarter, while LPG rate for 1400cc and below vehicles has been cut by 1p to 9p per mile. The previous rates, effective September 2019, 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.
The advisory electricity rate for fully electric cars is unchanged at 4p per mile. Electricity is not a fuel for car fuel benefit purposes.
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.
