At the moment, you don’t need to pay car tax for an electric car. They don’t emit any CO2 while driving so have a zero car tax rating, although you still need to to fill out the official paperwork each year, even though it won’t cost you anything.
The rules, however, are set to change on the first of April 2025, when electric cars will be subject to car tax for the first time. For the first year, you’ll pay the lowest rate of tax at £10, but from the second year you’ll need to pay the same flat rate as petrol and diesel cars (currently £180). Used electric cars registered between April 2017 and the end of March 2025 will also have to pay the flat rate.
Electric cars are currently exempt from the car tax surcharge on cars worth more than £40,000 when new, but that will also change in April 2025 when owners of EVs that cost more than £40,000 when new will be required to pay the surcharge (now £390 a year for five years).
