What Documents Do You Need to Tax a Car in the UK?
Taxing your car is a legal requirement if you want to drive or park it on public roads in the UK. The process is straightforward, but you need the right documents depending on which method you use.
Here is everything you need to know. For a broader guide to DVLA online services, see our DVLA Online Services Guide.

Documents Required
1. V5C Registration Certificate (Logbook)
The V5C is the main document linking you to the vehicle. It contains the vehicle's registration number, make, model, colour, and the registered keeper's details. You need the 11-digit reference number from the V5C when taxing online.
If you have recently bought the vehicle, you may have the green "new keeper" supplement (V5C/2), which can also be used to tax the car until the full V5C arrives.
2. V11 Reminder Letter
The DVLA sends a V11 reminder about six weeks before your road tax is due to expire. This letter contains a 16-digit reference number that you can use to tax your vehicle online or at the Post Office. If you have this letter, you do not need the V5C.
3. Valid MOT Certificate
Your vehicle must have a valid MOT at the time of taxing (unless it is exempt — e.g., under 3 years old or a historic vehicle). You do not need to present a physical certificate; the DVLA system checks the DVSA database automatically.
Not sure if your MOT is valid? Check it for free on CarFile. And if you are wondering whether you can tax without an MOT — the answer is almost always no.
4. Valid Insurance
Your vehicle must be insured. Again, you do not need to show proof — the DVLA cross-references the Motor Insurance Database (MID). However, it can take up to 48 hours for a new policy to appear on the MID, so allow time if you have just taken out insurance.

Special Situations
Just Bought a Vehicle
If you have just purchased a car, the previous owner's tax does not transfer to you. You must tax the vehicle in your name before driving it away. You can use:
- The green V5C/2 (new keeper supplement) provided by the seller
- The full V5C once it arrives from the DVLA (takes 2-4 weeks)
Many buyers tax the vehicle online immediately using the V5C/2 reference number while at the seller's location. Before buying, always run a free DVLA check to verify the vehicle's MOT and tax status, and check for mileage discrepancies.
Lost Your V5C
If you have lost your V5C, you can:
- Apply for a replacement online at gov.uk (costs £25)
- Use the V11 reminder if you have one — it works independently of the V5C
- Visit a Post Office with alternative identity documents
No V11 and No V5C
If you have neither document, you will need to apply for a replacement V5C before you can tax the vehicle. This typically takes 5-7 working days by post.

Payment Options

|---------------|---------------|-------------|
| 12 months upfront | ✅ Yes | ✅ Yes |
| 6 months | ✅ Yes (5% surcharge) | ✅ Yes |

Paying by Direct Debit allows you to spread the cost monthly, but there is a small surcharge (approximately 5%) compared to paying annually.

What If You Do Not Want to Tax Your Car?
If your vehicle is not being used on public roads, you must declare a SORN (Statutory Off Road Notification). This is free and means you do not need to pay road tax. However, the vehicle must remain off public roads at all times.
