Vehicle excise duty is an annual tax in the United Kingdom that is levied as an excise duty. The VED must be paid for most types of powered vehicles which are to be used or parked on public roads. Registered vehicles that are not being used or parked on public roads and which have been taxed since 31 January 1998 must be covered by a Statutory Off Road Notification (SORN) to avoid VED. In 2016, VED generated approximately £6 billion for the Exchequer.
