In order to receive a tax refund, you will need to inform DVLA that you have sold your vehicle. This can be done once the vehicle has been collected using the V5C (logbook) - section 9 or section 4 on the new logbooks issued in April 2019 (yellow section) which will be filled in on the day of collection by the driver, and handed back to you. You will need to send this to DVLA (we recommend recorded delivery). If you do not have the V5C, we advise you send a letter to DVLA using the address details of the collector to advise that you are no longer the registered keeper as of the day and time of the collection. For more information regarding the tax refund, please contact DVLA or visit https://www.gov.uk/vehicle-tax-refund.
