Car tax rules for a 2020 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
- Petrol cars first registered from 2006 usually meet Euro 4, the petrol standard for the London ULEZ, so they usually do not pay the daily charge.
- Hybrids follow the Euro standard of their petrol or diesel engine.
- Fully electric cars do not pay the ULEZ charge.
- The clean air zones in Birmingham and Bristol use the same Euro 4 petrol and Euro 6 diesel standards. The low emission zones in Scotland use them too, but enforce them with fines, not a daily charge.
The Euro standard of the car decides, not the year alone. ULEZ checker
