How Long After Buying a Car Do You Have to Tax It?

There is no grace period. The moment you buy a car in the UK, you have to tax it before you drive it on a public road, so the honest answer to how long after buying a car you have to tax it is zero minutes. Vehicle Excise Duty does not pass from the seller to you, and any tax the previous owner had paid is cancelled as soon as they notify the DVLA of the sale. Tax it before you turn the key.

Why the Previous Owner’s Tax Doesn’t Cover You

Before October 2014, VED stayed with the vehicle when it changed hands. That is no longer how it works. When the seller tells the DVLA about the change of ownership, any remaining tax on the car is automatically cancelled and the previous keeper gets a refund for the full months left.¹ From that point the car is untaxed, no matter how recently the old owner paid.

This catches buyers out. If you buy a car on a Saturday afternoon and the seller updates the DVLA that evening, the tax is gone before you wake up on Sunday. Driving it home without taxing it first is already an offence. Buying privately and planning to drive the car away? Tax it on your phone before you leave the seller’s driveway. Buying from a dealer? The dealership will usually arrange the first tax as part of the sale, but confirm that explicitly before you drive off the forecourt.

Taxing the Car Before You Drive It

You can tax a newly bought car in minutes using a reference number from one of three documents:

The new keeper slip (V5C/2), a green slip torn from the log book by the seller and handed to you at the point of sale. Its 12-digit reference lets you tax the car before the full log book arrives in your name.²
The vehicle log book (V5C), if it is already in your name, using its 11-digit reference number.
A DVLA tax reminder or “last chance” warning letter, using the reference number printed on it.³

Three channels are open around the clock. The GOV.UK vehicle tax service runs 24 hours a day, seven days a week and is the route most buyers use.⁴ You can also call the DVLA on 0300 123 4321, also 24 hours.³ Some Post Office branches handle vehicle tax in person, but you will need to bring the physical documents rather than just the reference numbers.

The car also needs a valid MOT if it is more than three years old. The DVLA’s system checks the national MOT database when you apply, and a freshly passed MOT can take up to two days to appear there. If you have just had the car tested, you might not be able to tax it online straight away.³ In Northern Ireland, you also need to show an insurance certificate or cover note if you tax at a Post Office.

Once the transaction goes through, the vehicle’s status updates on the national database immediately. Paper tax discs are gone. Enforcement cameras read your number plate and check tax electronically, so you can drive away as soon as the payment clears.

What You’ll Pay at the Point of Tax

What VED costs depends on when the car was first registered and how much CO2 it produces. For cars registered on or after 1 April 2017, VED works in two stages: a first-year rate based on emissions, then a flat standard rate from year two.

The first-year rate runs from £10 for a zero-emission vehicle up to £5,690 for the highest-polluting cars, so if you are buying a nearly-new car and paying its first year of tax, check the rate for your specific CO2 band before you commit. After the first year, nearly every car drops to a flat standard rate of £200 per year. If the car had a list price above £40,000 when new (or above £50,000 for electric vehicles), an additional £440 per year applies on top of the standard rate for five years starting from the second year of tax.⁵

Electric cars were exempt from VED until 1 April 2025. That exemption is gone. Buy an electric car now and you pay the same £200 standard rate as everyone else, with only the lower first-year rate of £10 and the higher expensive-car threshold of £50,000 remaining as concessions.⁶ Electric cars registered before 1 April 2025 with a list price under £40,000 still avoid the expensive-car supplement.

You can pay for 12 months in one go, six months at a time, or monthly by Direct Debit. Spreading the cost adds a surcharge: 5% for Direct Debit (monthly or six-monthly), and 10% for a single six-monthly card payment. Monthly payments are only available through Direct Debit; you cannot pay month by month with a credit or debit card.⁵

If You’re Not Going to Drive It Yet

Bought a car you plan to leave on private property for a while? You can declare a Statutory Off Road Notification instead of taxing it. A SORN tells the DVLA the vehicle will be kept off public roads and removes the requirement to tax or insure it while it stays there.⁷

A SORN does not transfer from the previous owner. Even if the seller had one in place, it does not carry over, and you have to make a fresh SORN declaration yourself before the car sits on DVLA records as untaxed with no notification against it. A vehicle that is neither taxed nor declared SORN triggers an automatic £80 fine.⁷

You can apply for a SORN online using the reference number from your V5C, by phone on 0300 123 4321, or by post using form V890. In most cases it takes effect immediately.⁸ The SORN stays in place until you tax the vehicle or sell it. Keeping a SORN vehicle on a public road, even parked, is an offence that carries harsher penalties than ordinary untaxed driving.

What Happens If You Drive Untaxed

The DVLA does not wait for a police officer to pull you over. Automatic Number Plate Recognition cameras mounted in enforcement vehicles scan plates constantly and check them against the tax database in real time.⁹ If your car shows up untaxed, enforcement follows automatically.

As the registered keeper of an untaxed vehicle, you receive an automatic late licensing penalty of £80, reduced to £40 if you pay within 33 days. If you are caught actually using the untaxed car on a public road, the DVLA issues an out-of-court settlement demand of £30 plus one and a half times the outstanding tax. Ignore the settlement and the case goes to magistrates’ court, where the fine is the greater of £1,000 or five times the tax owed. Driving an untaxed vehicle that also has a SORN declared raises the ceiling to £2,500 or five times the tax.¹⁰ Untaxed vehicles found on public roads can also be clamped on the spot or towed to a pound, with release fees payable on top of the tax you still owe.¹¹

All of which is avoidable in the two minutes it takes to tax the car at the point of sale.
