The best place to check vehicle road tax is the free vehicle tax checker on GOV.UK, run by the DVLA. You only need the registration number. It tells you whether the vehicle is currently taxed, has a SORN (Statutory Off Road Notification), or is untaxed. It takes less than a minute and needs no login. Motorpeek is an independent site and is not affiliated with the DVLA or the government.
How to check a vehicle's road tax step by step
- Search for 'check if a vehicle is taxed' and make sure you land on the GOV.UK page, not a third-party site that charges for the same thing.
- Enter the vehicle's registration number exactly as it appears on the number plate.
- Read the result. It shows the make, the tax status and the date the tax is due, along with the MOT status and expiry date.
- Check that the make and colour match the car in front of you. If they don't, ask why before going any further.
You can also see the tax status on your own vehicle through your DVLA online account, and your V5C logbook and any DVLA reminder letters show the details for a car you already own.
What the result tells you
The GOV.UK checker normally gives one of these outcomes:
- Taxed: the vehicle has current road tax, and the expiry date is shown.
- Untaxed: the tax has expired and has not been renewed. The vehicle must not be used on the road until it is taxed.
- SORN: the keeper has declared the vehicle off the road. It must be kept on private land, and it is not legal to drive it on public roads (apart from to a pre-booked MOT test).
The result is a snapshot of the DVLA record at that moment. It is a useful first screen, but it is not a full picture of the car's history.
Why tax status matters when buying a used car
Since 2014, road tax does not transfer with the vehicle when it is sold. The seller's tax ends when ownership changes, and the DVLA automatically refunds any full remaining months to them. That means a car can show as taxed on the day you view it and be untaxed by the time you drive it home.
As the new keeper, you must tax the vehicle in your own name before you drive it on a public road. You can do this online or by phone using the 11-digit reference number on the V5C, or the green 'new keeper' slip. You will also need valid insurance and, if the car is over three years old, a current MOT. Do not drive the car away on the seller's tax. It will not cover you.
Before you hand over any money, check that the car you are looking at has a sensible tax history. A long-running SORN or a recent lapse is not necessarily a problem, but it is worth asking why. The car may have been laid up, or it may have been off the road after an accident or repair.
What a road tax check will not tell you
Road tax status is one small part of a used car's story. The GOV.UK tax checker does not tell you whether the vehicle:
- Has been recorded as an insurance write-off (MIAFTR categories A, B, S or N)
- Is marked as stolen on the Police National Computer (PNC)
- Has outstanding finance that could affect your ownership
- Has a mileage that doesn't add up, which can point to clocking
- Has had many previous keepers
It is sensible to run a full vehicle history check as well. You can enter the registration at motorpeek.com to see the history details alongside the tax and MOT information. No check can guarantee a car is problem-free, so use the results alongside a proper inspection, a test drive and the paperwork.
Check the MOT history at the same time
The DVLA and DVSA also provide a free MOT history service on GOV.UK. It lists every MOT test result, the recorded mileage at each test, and any advisories and failures. Comparing mileage readings over the years is one of the quickest ways to spot a car whose odometer figures look odd. A missing MOT does not always mean a problem, but it does mean you should ask questions.
What happens if you drive without road tax
The DVLA matches its records against insurance and camera data, so untaxed vehicles are easy to find. Penalties can include:
- An automatic fine, which is currently £80 and may be reduced if you pay promptly
- A larger penalty if the case goes to court, which can be up to £1,000
- Clamping, removal or even destruction of an untaxed vehicle left on the road
If you are not using a vehicle, declare a SORN rather than letting the tax lapse. This avoids the penalties and makes your intentions clear to the DVLA.
Quick checklist before you buy
- Check the tax and MOT status on GOV.UK using the registration number.
- Make sure the details on the screen match the car and the V5C.
- Ask the seller about any gaps in tax, SORN periods or MOT history.
- Run a full history check for write-off, stolen and finance markers.
- Tax the car in your name before you drive it away.
Checking road tax is quick and free, and it can save you from an unpleasant surprise on the day you collect your car.
Frequently asked questions
Can I check if a car has road tax with just the registration number?
Yes. Enter the registration number into the free 'Check if a vehicle is taxed' service on GOV.UK. It shows whether the vehicle is taxed, untaxed or declared SORN, along with the MOT status. You do not need the V5C or any personal details.
Does road tax transfer to the new owner when you buy a used car?
No. Since October 2014, road tax does not transfer between keepers. The seller's tax is cancelled when the vehicle is sold, and they get an automatic refund for any full months left. You must tax the car in your own name before driving it on a public road.
What does SORN mean when I check a vehicle's tax status?
SORN stands for Statutory Off Road Notification. It means the keeper has told the DVLA the vehicle is not being used or kept on public roads, so no tax is due. The vehicle can't legally be driven on the road until it is taxed again, apart from going to a pre-booked MOT test.
