Company car tax diesel supplement

Diesel cars which meet the levels of Nitrogen Oxide (NOx) emissions permitted by Euro standard 6d, qualify for an exemption from the entire diesel supplement.

For cars manufactured after September 2018, the online Vehicle Enquiry Service will help you identify whether a car meets Euro standard 6d. For the 2019 to 2020 tax year, information will also be made available from the Driver Vehicle Licencing Agency (DVLA).

Euro standard 6d information is available on the form V5C for cars registered after 1 September 2018. If the Euro status of the car is shown as Euro 6AJ, 6AK, 6AL, 6AM, 6AN, 6AO, 6AP, 6AQ or 6AR, the car meets Euro standard 6d.

RDE2 (Euro standard 6d) will come into force from January 2020 for new type approvals and then from January 2021 for all new cars, which will be labelled Euro 6d.

How to report a Euro6d diesel company car.

From 6 April 2019, a new fuel type was made available on the P11D and P46 (car) called ‘Fuel Type F – Diesel cars meeting Euro standard 6d’. 

This fuel type should be used for reporting diesel company cars which are Euro standard 6d compliant. This replaces guidance which advised these cars being reported as fuel type ‘A’ up until this date.
