After 2 September 2004, Hutt River Province/Principality accepted company registrations. At least one company experienced in the registration of entities in traditional offshore jurisdictions (British Virgin Islands, Cayman Islands etc.) as tax havens were authorised to act as a registered agent for PHR incorporations. On 29 March 2005 the Hutt River Province International Business Company announced it would accept registrations of company trusts which have since been promoted worldwide by registered financial agents. Concerned that Hutt River registrations "may be sold as part of a tax avoidance or evasion arrangement", in April 2012 the Australian Taxation Office warned potential purchasers that the registrations have no legal basis and "could be illegal". Hutt River also allowed car registrations, including issuing licence plates to overseas vehicles.
