You forgot this. It's £180 if registered after 1/4/2017
Figure shown includes additional rate of £390 (per year) or £214.50 (per half year) levied on cars registered after April 1 2017 with a list price over £40,000. The additional rate is only applied for the first five years that road tax is renewed; renewals after that incur the standard rate for the car's fuel type.
