How to Tax a Car You Have Just Bought

When you buy a used car, the previous owner's vehicle tax (VED) is cancelled automatically and a refund goes to them. It does not carry over to you. You must tax the car in your own name before you drive it away, or you risk an automatic fine from a roadside camera.

Why Tax Never Transfers

The DVLA cancels the seller's tax the moment the vehicle changes hands. This rule has been in place since the paper tax disc was abolished in 2014. Even if the old disc showed months remaining, those months belong to the seller and they will receive a partial refund. You start from zero.

What You Need Before You Can Tax It

You will need three things in place before the DVLA will let you tax a car:

• A valid MOT. If the MOT has expired, you cannot tax the vehicle. Check the current MOT status for free at gov.uk using the registration number. BeakCheck also shows the full DVSA MOT history, including mileage at each test and any advisories, all from the reg.
• Valid motor insurance. The DVLA checks the Motor Insurance Database in real time. If the car is not insured, the tax application will be rejected.
• The reference number from the V5C or green slip. This is explained below.

The V5C and the Green Keeper Slip

When you buy privately, the seller should complete the yellow section of the V5C logbook and send it to the DVLA. You keep the green new keeper supplement (V5C/2). That green slip carries an 11-digit reference number you will need to tax online or at the Post Office.

If the seller has already sent the whole V5C off and you are waiting for a new one in your name, you can still tax the car using the 11-digit number from the green slip.

If you buy from a dealer, the dealer usually handles the V5C transfer. Ask them for the green slip or the V5C reference number before you drive away.

If there is no V5C or green slip at all, do not buy the car until the paperwork is sorted. No logbook is a serious warning sign.

How to Actually Tax It

Online (fastest): Go to gov.uk/vehicle-tax. You will need the 11-digit reference number and a payment method. The system confirms your MOT and insurance automatically. You can tax it at any hour.

By phone: Call the DVLA's automated service on 0300 123 4321. Have the reference number ready.

At a Post Office: Take the green V5C/2 slip (or the full V5C if you have it), your insurance certificate and MOT certificate. Not every Post Office handles vehicle tax, so check postoffice.co.uk for a branch that does.

Payment Options

Option	Notes
12 months	Cheapest overall
6 months	Available but costs more than half of annual
Monthly direct debit	Spread the cost, slight surcharge over the year

The rate depends on the car's CO2 emissions and fuel type, which are recorded on the V5C and the DVLA record. Electric cars currently pay no VED, though rates are subject to government changes so always confirm at gov.uk.

Can You Drive It to the Post Office Before It Is Taxed?

No. The only exception in law is driving to a pre-booked MOT test on an untaxed vehicle. Driving an untaxed car for any other reason, including driving to a Post Office to tax it, is an offence. Tax it online first, then collect the car, or tax it at a Post Office before you leave the seller's address.

What About SORN?

If you buy a car and it is going straight into a garage and will not be driven on a public road, you can declare it SORN (Statutory Off Road Notification) instead of taxing it. A SORN vehicle must not be parked on a public road either. You can register a SORN at gov.uk/make-a-sorn.

Before You Buy: Check the Tax and MOT Status

It is worth checking the car's tax and MOT status before you hand over any money. An expired MOT might mean the seller has been avoiding an MOT to hide a problem. A lapsed tax is less serious but worth querying.

Both are free to check at gov.uk or using BeakCheck's free lookup by registration number. BeakCheck also shows the full DVSA MOT history back to 2005, including recorded mileage at every test. A mileage reading that goes down or stays suspiciously flat between tests is a potential sign of clocking.

What a Free Check Will Not Tell You

The free DVLA record shows tax status, MOT status, fuel type, engine size and CO2, but it does not show the model name, and it will not flag outstanding finance, a stolen marker or an insurance write-off category (A, B, S or N). Those markers require a paid history check from a specialist provider. If you are spending a meaningful amount on a used car, that extra check is usually worth it.

Your Next Step

Tax the car before you drive it. Go to gov.uk/vehicle-tax, enter the 11-digit reference number from the green keeper slip, confirm your insurance is active, and pay. The whole process takes about five minutes and your tax is live immediately.
