Do I need to tax a car I have just bought?
Yes — before you drive it. Vehicle tax is never transferred on sale: DVLA cancels it and refunds the seller as soon as it is told the car has changed hands. Tax it in your own name using the reference on the V5C/2 green slip the seller gives you, or declare SORN if it stays off the road.
Why the tax did not come with the car
Vehicle tax belongs to the keeper, not to the car. When the seller notifies DVLA that the car has been sold, DVLA cancels the tax and refunds what is left of it to the seller automatically. That happens whether or not you have taxed it yet, so there is a moment, usually the moment you shake hands, when the car sitting in front of you is untaxed.
Nothing on the car tells you this. There is no tax disc to look at any more, and a car that was taxed when you viewed it a week ago can be untaxed by the time you collect it. Enforcement reads the DVLA register, not the windscreen.
How to tax it, and what you need
You need the reference number printed on the V5C/2 new keeper slip — the green slip the seller tears off the V5C logbook and hands to you as part of the sale. That reference lets you tax the car online, by phone or at a Post Office, in your own name, straight away.
If the seller does not give you the green slip, you cannot tax the car until DVLA issues a V5C in your name, which arrives by post. That is why the slip is worth asking for before any money changes hands, not after. The seller keeps the rest of the V5C and uses it to tell DVLA the car has been sold; the two actions are separate, and the seller notifying DVLA does not tax the car for you.
A car that is old enough to need an MOT must have a current one before it can be taxed. The first MOT falls due on the third anniversary of registration in Great Britain, and at four years in Northern Ireland. Our MOT check tool works out when the next test is due from a car's registration date, and points you to the free GOV.UK service that shows a specific car's own test history.
If it is not going on the road, declare SORN
If the car is going straight into a garage or onto a driveway and will not be used or parked on a public road, you declare it off the road instead — a Statutory Off Road Notification, or SORN. It is free, and it is the alternative to taxing, not an extra step alongside it.
A SORN does not carry over from the previous keeper any more than the tax does. If the seller had the car on SORN, that declaration ended when they told DVLA it was sold, and you have to make your own in your own name. A car on SORN has to be kept off the public road entirely, including the kerb outside your house.
How the rate is worked out: three registration regimes
What you pay is decided almost entirely by when the car was first registered, not by what you paid for it or how old it is now. There are three separate systems running side by side, and a used car stays in whichever one it was born into for the rest of its life. The figures below are the GOV.UK vehicle tax rates for 2026/27, checked on 28 July 2026.
| First registered | Taxed on | Annual rate (2026/27) |
|---|---|---|
| Before 1 March 2001 | Engine size only | £230 up to 1549cc, £375 above |
| 1 March 2001 to 31 March 2017 | CO2 band | £20 to £790 |
| On or after 1 April 2017 | Flat standard rate, plus a supplement on expensive cars | £200, plus £440 in years 2 to 6 if it applies |

One rate you will not pay is the first-year rate, the CO2-based charge often called showroom tax. It is paid once, by whoever first registers the car, and a used buyer never sees it — you pick up the standard rate instead. For completeness, a zero-emission car first registered on or after 1 April 2026 has a first-year rate of £10.
To put a figure on a particular car rather than a regime, our car tax calculator works from the registration date and CO2 figure, and the guide to vehicle tax when buying a used car covers the paperwork side in more depth.
Electric cars and the Expensive Car Supplement
Electric cars are taxed. A fully electric car registered on or after 1 April 2017 pays the same £200 standard rate as a petrol or diesel car of the same age.
The Expensive Car Supplement is £440 a year on top of the standard rate, charged in years 2 to 6. It bites when the list price when new was over £40,000 for a petrol, diesel or alternative-fuel car, or over £50,000 for a zero-emission car first registered on or after 1 April 2025, that higher threshold taking effect on 1 April 2026.
Two things about the supplement catch used buyers out. First, it turns on the list price when the car was new, which is not the price on the advert and is usually not shown anywhere on a used listing, so a car whose second-hand price is now far below the threshold can still be carrying it. Second, an electric car first registered between 1 April 2017 and 31 March 2025 pays the standard rate and no supplement at all, whatever its list price was.
Exempt from paying is not the same as untaxed
A car built before 1 January 1986 is exempt from vehicle tax from 1 April 2026. The exemption is not automatic: it has to be applied for, and the car still has to be taxed each year, at a zero rate. So the answer to the question at the top of this page is still yes, even for a car old enough to pay nothing.
This is a different rule from the historic MOT exemption, which people often assume is the same thing. In Great Britain a vehicle is exempt from MOT testing if it was built or first registered more than 40 years ago and has had no substantial changes in the last 30 years. That one is automatic and is declared on form V112, and it excludes substantially changed vehicles, Q-plated vehicles, kit cars, kit conversions and vehicles DVLA defines as reconstructed classics. Testing in Northern Ireland is run by DVA under its own rules, so do not read that exemption across to a Northern Ireland vehicle without checking the DVA position first. Two exemptions, two different tests, two different dates.
Northern Ireland
DVLA collects vehicle tax across the whole of the United Kingdom, so everything above applies in Northern Ireland too: the tax is cancelled on sale, and the new keeper taxes the car or declares SORN. One piece of paperwork is extra there — taxing a vehicle in Northern Ireland also needs an insurance certificate or cover note, which is not asked for in Great Britain.
What differs there is testing rather than tax. MOT testing in Northern Ireland is run by DVA rather than DVSA, and the first test falls at four years rather than on the third anniversary. Public MOT history also goes back only to 2017 in Northern Ireland, against 2005 in England, Scotland and Wales, so there is less history to read on an older car.
What vehicle tax does not cover
Taxing the car does not pay for a clean air zone. In London the ULEZ charge is £12.50 a day for a non-compliant car, every day except Christmas Day, across all London boroughs, and it is billed separately from vehicle tax. England has seven Clean Air Zones, but only the Class D zones in Birmingham and Bristol charge private cars at all. Northern Ireland has no ULEZ, Clean Air Zone or Low Emission Zone.
Whether a specific car is caught depends on its emissions standard rather than its age alone. Our clean air zone checker covers the London and English zones and the Scottish Low Emission Zones, and the glossary explains V5C, SORN, VED and the rest of the paperwork vocabulary in one place.
