How to Handle Car Tax When Changing Your Vehicle

Car tax does not move with the car when you change vehicle. The moment ownership transfers, the seller’s tax is cancelled and refunded, and the new keeper has to tax the vehicle fresh before driving it on a public road. That applies to private sales, dealer purchases, and cars handed over between family members. Getting the timing wrong triggers an automatic £80 penalty, so it’s worth walking through what each side has to do.¹

What the Seller Needs to Do

If you’re selling or giving away your old car, the paperwork is your responsibility. Until DVLA records the change of keeper, you remain liable for the vehicle. Parking tickets, traffic offences, and tax penalties will still come to you, and your tax refund won’t be issued.

The quickest way to notify DVLA is the online service at GOV.UK. Enter the reference number from your V5C logbook, confirm the change of ownership, and you’ll get an immediate confirmation receipt. Then tear out the green new keeper slip (section 6 on current logbooks) and hand it to the buyer. Destroy the rest of the old V5C so it can’t be misused.²

Once DVLA has recorded the sale, your tax is cancelled automatically and a refund cheque is issued for any full calendar months left. The refund runs from the date DVLA receives the notification, not the date you handed over the keys, and partial months don’t count. Selling early in a calendar month gives you a bit more back than selling late in one. The cheque goes to the address on the registration document, so update your address first if you’ve moved. If nothing arrives within eight weeks, contact DVLA.³

If you paid by Direct Debit, DVLA cancels the future payments when it processes the sale. A payment already in flight may still be taken, but it will be refunded automatically within 10 working days.⁴

What the Buyer Needs to Do Before Driving

Tax the vehicle before you drive it away. Not later that day, not once you’re home. Before. This is where private buyers get caught out most often, because no dealer is standing behind them handling it. The vehicle also needs valid insurance in your name and, if it’s old enough to require one, a valid MOT before DVLA will let you tax it.⁵

To tax the new-to-you vehicle, you need the 12-digit reference number from the green new keeper slip the seller gave you. Enter it at the GOV.UK vehicle tax service, confirm the details, and pay. The tax activates in DVLA’s database immediately, so you can drive as soon as the payment goes through. The service runs 24 hours a day.⁶

If you’d rather do it in person, certain Post Office branches handle vehicle tax. Bring the green slip, your payment or bank details, and evidence of a valid MOT if the vehicle needs one; a screenshot of the MOT history from GOV.UK is accepted.⁶

The green slip acts as your temporary proof of registration while DVLA processes the change and issues a new V5C in your name, which normally takes a few weeks. If the seller never gives you the slip, don’t drive the car; you can’t tax it without a reference number tied to the vehicle.

How You Can Pay

DVLA offers three payment patterns: a single annual payment, a six-monthly payment, or monthly instalments. Spreading the cost is not free. Paying every six months or monthly adds a 5% surcharge on top of the annual rate. Monthly and six-monthly plans have to be set up as Direct Debits; the annual option can be paid by debit card, credit card, or Direct Debit.⁷

A Direct Debit renews automatically at the end of each tax period, provided you’re still the registered keeper and the vehicle still has valid insurance and MOT. If a payment fails, DVLA can block you from using Direct Debit in future.¹

If You Are Not Driving the New Vehicle Straight Away

Every vehicle registered in the UK has to be either taxed or declared off the road with a Statutory Off Road Notification (SORN). There is no gap you can sit in. If you’ve bought a car you don’t intend to drive yet, make a SORN the same day you take ownership. Do neither and DVLA’s system issues an £80 late licensing penalty automatically, reduced to £40 if paid within 33 days.⁸

A SORN keeps the vehicle off public roads entirely. The only permitted trip is driving directly to or from a pre-booked MOT appointment. Using a SORN’d vehicle on the road for anything else can lead to prosecution and a fine of up to £2,500.⁸

What Happens if You Get the Timing Wrong

DVLA’s enforcement is largely automated, and the two typical situations attract different penalties.

If you’re the registered keeper of an untaxed vehicle and haven’t made a SORN, the system spots the gap and issues an £80 late licensing penalty, halved to £40 if you pay within 33 days. Ignore it and the debt is passed to a collection agency.¹

If you’re caught actually driving an untaxed vehicle, the numbers climb quickly. DVLA issues an out-of-court settlement of £30 plus one and a half times the outstanding tax. Unpaid cases go to a magistrates’ court, where the fine can be £1,000 or five times the unpaid tax, whichever is greater. The vehicle can also be clamped, with a £100 release fee within 24 hours. After that it’s impounded at £200 plus £21 per day in storage, and vehicles left unclaimed for 7 to 14 days can be crushed or sold.¹

The practical rule when you change vehicle is simple. On the day you sell, tell DVLA and hand over the green slip. On the day you buy, tax the car before you drive it, or SORN it if it’s staying put. The automated system leaves very little room for good intentions.
