HM Revenue & Customs has revealed the three most common mistakes that are costing companies and their drivers’ money:

Fleets not using the P11D price of a vehicle for tax purposes, but instead using the actual purchase price.

Not realising that new Euro IV diesels no longer avoid the 3% tax levy imposed on those vehicles and still taking off the amount when submitting returns.

Using incorrect CO2 emissions to calculate drivers’ tax bills, especially rounding the figure up to the nearest band level, rather than down.
