When to exchange

Exchange your tax disc if you change the:

• tax class - this doesn't apply for tax classes where no vehicle tax is payable
• engine size - cylinder capacity
• type of fuel used
• weight of a goods vehicle
• number of seats on a bus
• the use of a vehicle you have just bought

If the fuel type or engine size has changed

For changes to the fuel type or engine size, which needs a lower rate of vehicle tax to be paid, you must provide documentary evidence of the change. This can be the receipt for the new engine, written evidence from the manufacturer, insurance company or garage that carried out the change.

Extra payment of vehicle tax

To calculate the extra vehicle tax:

• check out the new rate of vehicle tax
• work out the difference between the old and new rates of your current tax disc - eg £100 old rate less £130 new rate is £30
• divide this by the period of your current tax disc - eg £30 divided by 12 months is £2.50
• multiply this by the number of months left to run on the tax disc - eg £2.50 multiplied by four months left to run is £10
• the extra tax payable is £10

• Check the rates of vehicle tax
