HMRC advisory fuel rates for company car users from 1 June 2023

The advisory fuel rates that apply from 1 June 2023 have decreased by between 1p and 2p for all diesel engine sizes, while unleaded rates remain unchanged. There is a minimal increase in LPG engine rates compared with the March 2023 rates. 

The previous rates, effective from March 2023, 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.

From 1 June 2023 the advisory electricity rate for fully electric cars remains at 9 pence per mile. In line with advisory fuel rates, this electric rate is now being reviewed quarterly.

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.
