In the UK, there is no sales tax, stamp duty or purchase tax when you buy a used car. You pay the agreed price and nothing extra for the act of buying. The two things people usually mean by 'tax' are VAT, which depends on who sells the car, and vehicle tax (Vehicle Excise Duty, or VED), which you must sort out before you drive away.
Do you pay VAT on a used car?
It depends on who you buy from.
- Private seller: no VAT is charged. The price you agree is the price you pay.
- Car dealer: most used cars are sold under the VAT margin scheme. VAT is already built into the dealer's profit margin, so it isn't shown as a separate line and you can't reclaim it.
- VAT-qualifying cars: some cars, often ex-company or commercial vehicles, are sold with VAT shown on the invoice. This is mainly relevant to VAT-registered businesses, which may be able to reclaim it. Private buyers simply pay the total.
If a price looks unusually high or low, ask the seller whether VAT is included and how it is shown on the paperwork.
Vehicle tax (VED) does not transfer to you
This is the part that catches many buyers out. Since October 2014, vehicle tax is not transferable between owners. Whatever tax the previous keeper had paid ends when the car is sold, and you must tax the car in your own name before you drive it.
You can't legally drive a car on a public road without tax, unless it has a valid SORN (Statutory Off Road Notification) and you're only driving it to a pre-booked MOT appointment. Don't rely on the seller saying the car is still taxed, because that tax no longer applies to you.
How to tax a used car you've just bought
- Use the new keeper section of the V5C logbook, or the reference number from the new keeper slip, on the GOV.UK vehicle tax service.
- You'll need valid insurance in place first, and the car will usually need a current MOT if it's over three years old.
- You can pay for 6 or 12 months in one go, or by Direct Debit, which may add a small surcharge compared with paying annually.
The previous keeper should get an automatic refund for any full months of tax remaining once they tell the DVLA they've sold the car. That refund is theirs, not yours, so don't expect it to be reflected in the price.
How much is vehicle tax on a used car?
The cost depends on when the car was first registered:
- Registered before March 2001: tax is based on engine size.
- Registered March 2001 to March 2017: tax is based on CO2 emissions bands, so lower-emission cars cost less.
- Registered from April 2017: a standard flat rate applies after the first year. Used buyers generally pay this standard rate rather than the higher first-year rate.
- Expensive cars: cars with a list price above a set threshold can attract an extra supplement for several years.
- Electric cars: the rules changed in April 2025, so check the current rate for the specific car.
- Historic vehicles: cars over 40 years old may be exempt, but they still need to be taxed (at a nil rate).
Rates change, so always check the current figure on GOV.UK for the exact vehicle before you buy.
What happens if you don't tax it?
The DVLA uses automated number plate recognition and its own records to spot untaxed vehicles. You can face an automatic penalty, and in some cases the vehicle can be clamped or impounded. If you aren't going to use the car straight away, declare a SORN instead.
Other costs to budget for
Although there's no purchase tax, the real cost of a used car can still add up:
- Vehicle tax (VED) and insurance before you drive away
- A new MOT if the current one is about to expire
- Servicing or repairs the car may need
- Any dealer admin fees, which are not a tax and can sometimes be queried
Check the car before you pay
Tax is only one part of the picture. Before you hand over any money, check the car's history for outstanding finance, insurance write-off records (MIAFTR Cat A, B, S or N), a police stolen marker, mileage anomalies that could suggest clocking, and previous keepers. Reviewing the MOT history can also reveal repeated failures or advisories. You can start by entering the registration on motorpeek.com. No check can guarantee a car is problem-free, so combine it with an in-person inspection and a test drive.
Quick summary
- No purchase tax or stamp duty on used cars in the UK
- No VAT on private sales; dealers usually include it under the margin scheme
- Vehicle tax does not transfer, so you must tax the car yourself before driving
- Check the V5C, MOT history and vehicle history before paying
Frequently asked questions
Do you pay VAT when buying a used car from a private seller?
No. Private sellers don't charge VAT, so the price you agree is the total you pay. VAT is only relevant when buying from a VAT-registered business, and even then it is usually already included in the price.
Does the car's road tax transfer to me when I buy it?
No. Vehicle tax (VED) has not transferred between owners since October 2014. You must tax the car in your own name before driving it, and the previous keeper receives any refund for the remaining full months.
Can I drive a used car home if it has no tax?
Generally no. An untaxed car can't legally be driven on public roads, apart from to a pre-booked MOT appointment if it has a SORN. The simplest approach is to arrange insurance and tax the car online before you collect it.
