Frequently Asked Questions

What is road tax?
Road tax, also known as Vehicle Excise Duty (VED) in the UK, is an annual tax paid on vehicles used on public roads. The amount depends on factors like vehicle age, fuel type, CO2 emissions, and engine size. It funds road maintenance and infrastructure projects.

What is the first year road tax rate?
The first year rate (also called showroom tax) applies to new cars and is based on CO2 emissions. It ranges from �0 for electric vehicles to over �2,000 for high-emission vehicles. After the first year, the standard rate applies.

What happens if I dont pay road tax?

Can I get a road tax refund?
When you sell, scrap, or declare a vehicle off the road (SORN), you can claim refund of any full months remaining on your road tax. Refunds are automatically processed when you notify DVLA of the changes.
What is a SORN?
SORN (Statutory Off Road Notification) declares that your vehicle is not being used on public roads. You do not need to pay road tax while SORN is in effect. You must keep the vehicle off public roads and cannot park it on public streets.
How are older vehicles taxed?
Cars registered before March 2001 are taxed based on engine size rather than CO2 emissions. Vehicles with engines under 1549cc pay a lower rate, while those over 1549cc pay a higher rate. Classic cars over 40 years old are exempt from road tax.
What is the road tax for classic cars?
Vehicles manufactured more than 40 years ago are exempt from road tax in the UK. You still need to apply for the exemption and display a tax disc-free status. This exemption encourages preservation of historic vehicles.
How does road tax vary by country?

Road tax costs significantly influence vehicle purchasing decisions. Low-emission vehicles save hundreds annually in road tax. Buyers often choose vehicles with lower CO2 emissions to reduce ongoing tax costs, accelerating the shift to electric and hybrid vehicles.
What is the environmental impact of road tax?
Road tax based on CO2 emissions incentivizes cleaner vehicle choices. The graduated system encourages manufacturers to produce lower-emission vehicles and buyers to choose them, contributing to reduced carbon emissions from transportation.
Can I pay road tax monthly?
