HMRC has published the latest table of advisory fuel rates, which apply to all journeys on or after 1 December 2012 until further notice.
Advisory fuel rates are HMRC-approved rates which apply where employers reimburse employees for business travel in their company cars, and where employees reimburse the cost of fuel used for private travel in a company car. Using the advisory rates will mean that there is no fuel benefit charge. HMRC will also accept the figures in the table for VAT purposes, though employers will need to retain receipts.
The only change is to the LPG rates, which have all gone done by 1p per mile. Rates for petrol and diesel have not changed. The rates from 1 December 2012 are set out on HMRC's website here.
