Car tax rules for a 2021 car
- Cars first registered from 1 April 2017 pay a first-year rate set by CO2 emissions, then the standard rate each year. A petrol, diesel or hybrid car with a list price over £40,000 also pays the expensive car supplement for five years, from the second tax payment.
- Electric cars have paid vehicle tax since 1 April 2025, under the rules for their registration date.
- Electric cars registered before 1 April 2025 do not pay the expensive car supplement.
These are the rules, not the amount for a specific car. Car tax check
ULEZ and clean air zones
- Fully electric cars do not pay the ULEZ charge.
- Clean air zones that charge cars, such as Birmingham and Bristol, do not charge fully electric cars.
The Euro standard of the car decides, not the year alone. ULEZ checker
