HMRC advisory fuel rates for company car users from 1 September 20th September 2018 HMRC has published the latest advisory fuel rates (AFR) for company car users, effective from 1 September 2018 reflecting the upward trend in forecourt fuel prices for higher emission cars. These rates apply from 1 September 2018 and have increased slightly on the previous quarter rates, for petrol cars with engine of 1400cc or more and diesel cars with an engine size less than 1600cc. 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.
