"if your annual car insurance premium is £400, your total cost will be £448 when factoring an IPT rate of 12 per cent or £480 at the higher rate of 20 per cent. If your premium cost is £500, it will be £560 with an IPT rate of 12 per cent or £600 with a rate of 20 per cent.
IPT was introduced in October 1994, and the standard rate has increased from 2.5 per cent to its current level of 12 per cent."
