The car registration must be surrendered to the car recycling company to cancel the vehicle tax. If you have a Direct Debit in place for your tax, this will be automatically cancelled by the DVLA and any full months paid for which have not been used will be refunded.
A cheque will be issued and made payable to the registered keeper of the vehicle. If you own the car but you are not the registered keeper, you can write or contact the DVLA with proof of your ownership, such as a bill of sale.
In this instance, provide your name, address and car registration number. You should also mention that you would like the car tax refund sent to your address.
