The 1st December 2020 Advisory Fuel Rates (AFR) have been cut by 1p per mile for petrol vehicles with engines of 1400-2000cc, while the diesel amount per mile for vehicles across all engine sizes remains unchanged.
The rates can only be applied to:
- reimburse employees for business travel in their company cars; or
- require employees to repay the cost of fuel used for private travel.
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.
