There are several ways of changing vehicle tax class. One method is to send the completed V70 form 'Application to exchange vehicle tax' to DVLA.
CHANGE CAR TAX CLASS: There are times when a change of vehicle tax classification is mandatory.
You must change vehicle tax class if you make any changes that affect:
DVLA tax class (exceptions apply on some VED rates exempt from vehicle tax).
The vehicle engine size (cubic capacity) or the type of fuel it uses.
The vehicle weight (goods vehicles only).
The number of seats on a bus.
The main use of the vehicle (e.g. start charging passengers in a minibus).
You will need to supply DVLA with a payment method to change taxation class. They may also need some extra documentation for vehicle tax change. The specific application forms needed will depend on the type of vehicle you have.
As a rule, vehicle tax is exempt, or paid at a lower rate, where it gets used by:
A disabled person.
An organisation that provides transportation for disabled people.
Different Methods for Changing Vehicle Tax Class
The correct method to change taxation class depends on whether:
The vehicle tax is not due to expire.
The vehicle tax is due to expire (e.g. you received a reminder or a DVLA 'last chance warning letter'.
You make changes that affect vehicle tax exemption (e.g. disabled car tax change of vehicle).
Then you need to calculate the difference between the old and the new rates of your current vehicle tax. For example, if the old rate is £200 and the new rate is £260, then the difference would be £60.
The next step is to divide the difference by the number of months you pay tax over. For example, £60 divided by 12 months is £5.
Then multiply this by the number of months that remain on the tax. For example, 5 multiplied by 6 months is £30.
Having calculated the new rate you must then pay the extra vehicle tax. In this particular example you would need to pay £30 extra tax.
If Tax Rates Increase or Decrease
When the tax rate increases you must pay the higher rate from the first day of the month that you change the tax rate in. You would pay the lower rate from the first day of the next month if the tax rate decreases.
Change Tax Class: Not Due to Expire
Use the V70 form to change vehicle tax class providing the tax is not close to running out. There is a different method for those who get the reminder letter or the 'last chance' warning letter.
In some cases you must change car tax class at a Post Office branch that deals with road tax. This applies where the vehicle tax is due to run out, you received a reminder, or you got a 'last chance' warning letter.
Also change tax class at a Post Office for changing vehicles that are exempt from road tax (or not). An example would be changing car tax from disabled to normal.
Change Vehicle Tax Class at Post Office
What if you are missing your DVLA V11 reminder letter or the V5C Registration Certificate? You can still pay for your vehicle road taxation at certain branches of the Post Office.
You will need to take:
The V5C vehicle registration certificate (log book) in your name. Use the new keeper supplement V5C/2 if you recently bought the vehicle.
The DVLA vehicle tax reminder letter (V11) (if you have it).
A valid MOT test certificate from when the tax starts. Take evidence if your vehicle is exempt from an MOT (V112).
