Can I check my car tax price?
Yes. The UK government provides a free online service that lets you look up the current road tax (Vehicle Excise Duty) for any registered vehicle. All you need is the registration number.
Why knowing the tax price matters
Road tax is a regular cost of owning a car, and the amount you pay depends on the vehicle’s CO2 emissions, engine size, fuel type and the date it was first registered. When you are buying a used car, understanding the tax liability helps you budget accurately and avoid unpleasant surprises.
Where to check the tax price
The most reliable source is the official Check vehicle tax service on GOV.UK. It pulls data directly from the DVLA database, so the figure you see is the one you will be charged if you keep the vehicle.
Steps to check the tax price
- Visit the GOV.UK vehicle tax checker.
- Enter the full registration number (e.g., AB12 CDE).
- Press “Continue” – the page will display the current tax rate, the next renewal date and the amount due.
What influences the tax amount?
The calculation changed in April 2017. Since then the main factors are:
- CO2 emissions: Lower emissions mean lower tax bands.
- Fuel type: Diesel, petrol, hybrid and electric vehicles are taxed differently.
- Engine size: For cars first registered before March 2001, engine capacity still matters.
- Age of the vehicle: Cars over 40 years old are exempt.
Alternative ways to find the tax price
If you cannot use the GOV.UK service, you can also:
- Check the vehicle’s V5C registration document – the tax band is printed on the front page.
- Ask the seller for a recent MOT certificate – it often shows the tax due date and amount.
- Use a reputable vehicle‑history check site such as motorpeek.com. While the primary focus is on MOT history, insurance write‑offs and finance, the report also includes the current tax band, giving you a quick snapshot.
Common pitfalls
Be aware that the tax price shown online is the amount for the next full year. If you buy a car part‑way through a tax period, the DVLA will automatically calculate a pro‑rata charge for the remaining months. Also, tax rates can change each year when the government updates emission bands, so always check the latest figure before finalising a purchase.
What to do after you’ve checked the price
Once you know the tax amount, you can decide whether the vehicle fits your budget. If the tax is higher than expected, consider alternatives with lower emissions or hybrid powertrains – they often enjoy reduced rates.
When you are ready to buy, make sure the seller has cleared any outstanding tax. An unpaid tax does not stop you from registering the vehicle, but you will inherit the debt, which can affect your credit score.
Quick recap

- Tax depends on CO2 emissions, fuel type, engine size and age.
