What Exactly is Car Tax (VED)?
Car tax, or Vehicle Excise Duty (VED), is a mandatory annual payment that every vehicle owner in the United Kingdom must make to legally drive or park their vehicle on public roads. Originally, the revenue generated from VED was exclusively ring-fenced for road maintenance. However, over time, this policy evolved, and the funds are now allocated to broader government expenditure. The primary purpose of VED remains to contribute to the upkeep of the nation's road infrastructure and to manage vehicle emissions through tiered taxation based on environmental impact.
How is UK Car Tax Calculated?
The calculation of car tax in the UK has evolved significantly over the years, with different methods applying depending on the vehicle's registration date. The key factors influencing the tax amount are primarily CO2 emissions and the vehicle's list price.
Vehicles Registered From 1 April 2017 Onwards:
For cars registered on or after 1 April 2017, the system is based on a tiered structure linked to CO2 emissions. There are 13 different tax bands, each corresponding to a specific level of CO2 output and a corresponding tax rate. The First Year Rate (FYR) is applied for the initial 12 months of the vehicle's life, with subsequent years falling under a standard rate.
A significant change for newer, more expensive vehicles is the introduction of a supplement for cars with a list price of £40,000 or more. This supplement applies for five years, starting from the second year of registration, and is added to the standard VED rate, regardless of the car's CO2 emissions. This means that higher-value vehicles, even if environmentally friendly, will incur a higher tax burden during their first five years.
Vehicles Registered Between 1 March 2001 and 31 March 2017:
For vehicles registered within this period, car tax is calculated solely based on their CO2 emissions. The tax bands are structured to encourage the purchase of lower-emission vehicles, with higher CO2 outputs attracting higher tax rates.
Vehicles Registered Before 1 March 2001:
Older vehicles, those registered before March 2001, have their car tax calculated based on their engine capacity in cubic centimetres (cc). The dividing line for different tax rates is set at 1549cc. Vehicles with an engine capacity below this threshold fall into one tax band, while those with larger engines fall into a different, typically higher, tax band.
Using the Parkers Car Tax Calculator
If you're wondering how much your current car is taxed for, or want to estimate the tax cost for a potential new purchase, the Parkers car tax calculator is an invaluable tool. It's designed for ease of use:
- Select Make and Model: Use the dropdown menus to choose your car's manufacturer and specific model.
- Specify Bodystyle and Year: Select the relevant bodystyle and the year of manufacture. If your exact year isn't listed, choose the closest available year or range.
- View Tax Rates: Click the 'go to' button to be taken to a page detailing the tax rates applicable to vehicles matching your selection.
If you're unsure about your car's exact specifications, the Parkers Car Valuation Tool can help. Simply enter your vehicle's registration number to get precise details on its make, range, and model.
Company Car Tax (BIK)
For individuals who receive a company car as part of their employment benefits, a different tax system applies: Company Car Tax, also known as Benefit-in-Kind (BIK) tax. This is calculated based on the car's P11d value (the price the car would have cost the employer if it were new), your personal salary, and the car's CO2 emissions. The system is quite complex, and Parkers offers a dedicated Company Car Tax section to provide more in-depth information.
Key Questions About Car Tax Answered
Q: What is car tax and why is it so important?
A: Car tax, or Vehicle Excise Duty (VED), is a legal requirement for all vehicle owners in the UK. It allows you to drive or park your car on public roads and contributes to road maintenance and other public services.
Q: Why do I have to pay car tax?
A: UK drivers are legally obligated to pay car tax annually. It was initially introduced to fund road maintenance, though this has broadened over time.

Q: What happens if I get caught with an untaxed car?
A: Driving or keeping a vehicle on a public road without valid car tax can lead to significant penalties. You could face a fine of up to £1,000. The DVLA has the authority to clamp untaxed vehicles found on the street, and in some cases, they may be impounded. If your vehicle is clamped, you'll incur a £100 release fee. To get it released without further charges, you must provide proof of valid tax within 15 days; otherwise, a further surety fee of £160 applies (which is refundable upon valid taxing).
Q: Is my car taxed? How to check online
A: Checking your car's tax status is straightforward. Visit the official DVLA website and enter your vehicle's registration number. The system will quickly confirm if your car is currently taxed.
Q: How are high-end new or secondhand cars affected by car tax?
A: New vehicles with a list price exceeding £40,000 are subject to an additional annual supplement of £310 for the first five years after the initial registration. This is on top of the standard VED rate. For cars registered before 2017, tax is based on emissions, so gas-guzzlers will generally attract higher rates.
Q: Which documents do I need to renew my tax?
To renew your car tax, you will typically need:
- A DVLA reminder letter (V11) or your vehicle logbook (V5C) to obtain the 11-digit reference number for online applications.
- An up-to-date MoT certificate if your car is four years or older and you are taxing it at a Post Office. (This is checked automatically when applying online).
- Proof of insurance – either an insurance certificate or cover note, especially if taxing at a Post Office.
Q: How do I tax my new car?
When you purchase a brand-new car, the dealership usually handles the initial registration process and will provide you with the necessary reference number to tax your vehicle.
Q: Do I still need a tax disc for my car?
No, the physical tax discs were phased out in 2014. All vehicle tax is now managed electronically. While obsolete, old tax discs can be collector's items.
Q: I don’t have my DVLA reminder or my registration document. Can I still renew my vehicle tax at the Post Office?
Yes. If you've misplaced your V5C (logbook), you can still tax your vehicle at a Post Office by completing a V62 form.
Q: My vehicle has been off the road. Can I still tax it?
If you have declared your vehicle as SORN (Statutory Off-Road Notification) and are now returning it to the road, the re-taxing process is simple. You can do this online or by contacting the DVLA directly over the phone. You will need the 11-digit reference number from your vehicle logbook. Ensure your vehicle has a valid MoT and is insured before you tax it. If its MoT has expired, you will need to get it re-tested before you can tax it.
Q: My vehicle is free to tax. Do I have to do anything?
Yes, even if your vehicle qualifies for zero-rate tax (which includes some pre-2017 models with low CO2 emissions and certain classic cars), you still need to complete the necessary paperwork to tax it. While an MoT may not be strictly required before renewing the tax for zero-rate vehicles, you must ensure the vehicle will pass its MoT test.

|---|---|---|
| Before 1 March 2001 | Engine Capacity (cc) | Dividing point at 1549cc. |
| 1 March 2001 - 31 March 2017 | CO2 Emissions | Higher emissions = higher tax. |
| From 1 April 2017 | CO2 Emissions & List Price | 13 CO2 bands. £40,000+ list price incurs a 5-year supplement. |
