Selling your car involves several road tax responsibilities that, if overlooked, can leave you liable for charges on a vehicle you no longer own. Understanding the tax transfer process protects sellers from unexpected bills and ensures buyers can tax the vehicle legally.
Road Tax Does Not Transfer to the Buyer
One of the most common misconceptions is that road tax transfers with the vehicle. It does not. Road tax is tied to the registered keeper, not the vehicle. When you sell your car, your VED is cancelled and any unused months are refunded automatically — but only when DVLA is notified of the change of keeper. This is why notifying DVLA promptly is critical.
How to Notify DVLA of the Sale
You can notify DVLA of a vehicle sale in two ways. The first is to give the buyer the green slip — part V5C/2 of your registration certificate — on the day of sale. The buyer uses this to tax the vehicle in their name. The second is to notify DVLA online at GOV.UK using the 'sold a vehicle' service, which requires your V5C reference number. Both methods are equally valid. If you use the online service, you do not need to send any part of the V5C to DVLA.
What Happens to Your Road Tax
Once DVLA processes the change of keeper, your road tax is cancelled automatically. Any full months of unused tax are refunded to the registered keeper — that is you. The refund is calculated from the date DVLA processes the notification, not the date of sale. Refunds typically arrive within four to six weeks via bank transfer if you provided bank details, or by cheque to the address on your V5C.
Do Not Tax the Car for the Buyer
Some sellers offer to tax the car for the buyer as part of the sale. While well-intentioned, this creates problems. The tax would be in the seller's name, meaning the buyer cannot drive legally and the seller remains liable. Instead, agree with the buyer that they will tax the vehicle using the green slip you provide. The buyer can tax immediately online at GOV.UK before driving.
SORN Automatically Applies After Sale
If you sell the vehicle and the buyer has not yet taxed it, a SORN is automatically applied to protect both parties. This means the vehicle cannot be driven on the road until it is taxed by the new keeper. The SORN remains in place until either the new keeper taxes it or the 14-day notification window expires. DVLA sends a confirmation letter when the SORN is applied.
Private Number Plates and Tax
If you are selling the car but keeping a private number plate, take the plate off the vehicle before the sale. You can transfer the number to a retention certificate online at GOV.UK. The vehicle's road tax is unaffected by the number plate — the V5C tracks the vehicle, not the registration mark. The new keeper will receive a new registration number with the vehicle.
Check Your V5C Is in Your Name Before Selling
If you bought the car and the V5C is still in the previous owner's name, you cannot legally sell it or notify DVLA of the sale. You must first register yourself as the keeper on the V5C before selling. This is a common issue with private purchases where the seller never sent the slip to DVLA.
