How to change your vehicle鈥檚 tax class
How you change your vehicle鈥檚 tax class depends on if:
- the tax is due to run out (you鈥檝e had a reminder or 鈥榣ast chance鈥� warning letter)
- the tax is not due to run out
- 测辞耻鈥檙别 changing whether or not the vehicle is exempt from vehicle tax, for example changing a car into or out of the disabled tax class
2. Work out the new tax rate
You need to work out if you鈥檒l need to pay more tax because of the change.
-
Find out the new rate of vehicle tax.
-
Work out the difference between the old and new rates of your vehicle tax. For example, if the old rate is 拢100 and the new rate is 拢130, the difference is 拢30.
-
Divide the difference by the number of months you pay your tax over. For example, 拢30 divided by 12 months is 拢2.50.
-
Multiply this by the number of months remaining on the tax. For example, 拢2.50 multiplied by 4 months is 拢10.
-
Pay the extra vehicle tax. In this example you would need to pay 拢10 extra tax.
If the tax rate increases
You have to pay the increased rate from the first day of the month you change the tax rate in.
Example
If you change the tax class on 25 March, you鈥檒l have to pay the increased rate from 1 March.
If the tax rate decreases
You pay the decreased rate from the first day of the next month.
Example
If you change the tax class on 25 March, you鈥檒l pay the decreased rate from 1 April.
