Road tax

How to check if a car is taxed

Checking whether a car is taxed takes seconds and only needs the registration. If you're buying one, it's also worth knowing that the tax doesn't come with the car.

In short

  • Check tax with just the registration, free, on GOV.UK or with our free check.
  • Road tax doesn't transfer when a car is sold. The buyer must tax it before driving it.
  • You can tax it straight away online, using the reference on the green new keeper slip (V5C/2).
  • “Untaxed” can mean the car is SORN (declared off the road), so it mustn't be driven or parked on a public road.

How to check

Enter the registration in the Your Car Data free check to see whether the car is taxed, when its tax runs out, and whether its MOT is in date, along with its full MOT history. You can also check tax status on GOV.UK.

If you're buying, compare what the check says with the seller's story. A car that's been untaxed for a long time may have been off the road, and that's worth asking about.

Tax doesn't transfer to a new owner

Since October 2014, a car's tax is cancelled when it changes hands. The seller gets a refund for any full months left, and the buyer has to tax the car before driving it, even just to drive it home. That's why a car can show as taxed when you view it and untaxed the day after you buy it.

Tax it before you drive away. You can tax a car online or by phone straight away, using the reference number on the green new keeper slip (V5C/2) the seller gives you. You'll also need insurance in your name. Our buying checklist covers everything to do after you buy.

What “untaxed” and SORN mean

Our records show when a car's tax ran out, but not always whether it was then declared SORN. If you need to know, check on GOV.UK.

Penalties for driving untaxed

An untaxed car can be fined, clamped or taken away. The DVLA uses number-plate cameras and its own records to find untaxed vehicles, and send an automatic fine. If it goes to court, the fine can be £1,000 or more. A car also needs a valid MOT (if it's old enough) and insurance before it can be taxed. See our guide to checking MOT history.

How much will the tax cost?

Road tax (Vehicle Excise Duty) depends on when the car was first registered, its CO₂ emissions or engine size, and for newer cars, its list price when new. Cars first registered from April 2017 pay a flat yearly rate. If they cost more than £40,000 new (£50,000 for electric cars), they also pay an “expensive car” supplement of £440 a year for five years, starting from the second time the car is taxed. Electric cars now pay road tax too, though electric cars registered before April 2025 don't pay the supplement. The full history check shows the 6- and 12-month tax rates for the car you're looking at. You can also find them on GOV.UK.
