Car tax V5C logbook UK — the V5C registration certificate is the most important vehicle document for road tax purposes. Here is everything you need to know about the V5C and how it relates to your vehicle tax in 2026.

What Is the V5C Registration Certificate?

The V5C (also known as the vehicle logbook) is the official DVLA document that proves who the registered keeper of a vehicle is. It contains all the key details used to calculate road tax: the vehicle's CO2 emissions figure, fuel type, first registration date, and vehicle age. Every taxed vehicle must have a V5C registered to the current keeper.

Key Information on the V5C for Road Tax

  • CO2 emissions (section D): The g/km figure used to determine VED band
  • Fuel type (section F): Petrol, diesel, electric, hybrid, etc.
  • First registration date: Determines whether first-year or standard rates apply
  • Vehicle's list price: Used for premium rate determination (vehicles over £40,000)

Change of Keeper and Road Tax

When you buy a vehicle, the new keeper must notify DVLA using section 2 of the V5C (the green slip). Road tax does not transfer with the vehicle — the new keeper must tax the vehicle in their own name before driving. The previous keeper's road tax is cancelled and any unused months refunded.

Lost or Damaged V5C

If your V5C is lost, stolen, or damaged, you can apply for a replacement at GOV.UK. A new V5C will be issued with the same details, including your CO2 figure. There is a fee for replacement. Do not drive an untaxed vehicle while waiting for a replacement — tax online first and provide the V5C reference number.
