If your vehicle is registered in the UK, you need to pay road tax. Road tax is also known as vehicle excise duty, vehicle tax or car tax.

How is road tax determined?

Road tax is calculated based on the official CO2 emissions of the car, its engine and its fuel type. The Government has prescribed 13 tax bands between 'A' to 'M' on the basis of CO2 emissions in grams for each kilometre. Other factors determining the road tax are the year of registration of the vehicle as cars registered after 1st April 2010 have to pay a higher road tax. For vehicles using alternative fuels, the road tax is marginally lower when compared to petrol and diesel cars.

The cars with the lowest carbon emission fall in the tax band 'A' and the ones with the highest emission are in band 'M'. Vehicle owners in tax band 'A' do not have to pay any road tax. Electric vehicles such as BMW i3, Tesla Model S, Renault ZOE and Twizy, and Nissan Leaf fall under the tax band 'A'. For vehicles in tax band 'M,' the road tax can go be as high as £1,090 per year.

If your car is between bands B to D, you don't have to pay road tax during the first year.

Let's look at Ford Fiesta, which is expected to be 2014's top selling car, and the different road tax payable on the basis of the model and the engine type.


  • The Ford Fiesta (02-08) with a 1.4 Zetec 3d Auto (04) engine has CO2 emissions of 152 gm per kilometre. It falls under the 'G' tax band, and its annual road tax is 180.
  • The same Ford Fiesta (02-08) with a 1.25 Zetec 3d (04) engine has lower CO2 emissions of 147 gm per kilometre, and so it falls in a better tax band 'F' with a lower road tax of 145 every year.
  • If you go for a Ford Fiesta (08 on) with a 1.0 EcoBoost Zetec 5d Powershift engine, the CO2 emissions are much lower at 114 gm per kilometre. So it falls under vehicle tax band 'C', and the vehicle tax will be 30 per year. Note that since this particular model is in band 'C' there will be no tax for the first year.
