components: Fixed refers to a link between the place of business and a specific geographic point, as well as a degree of permanence with respect to the taxpayer. An "office hotel" may constitute a fixed place for a business for an enterprise that regularly uses different offices within the space. By contrast, if there is no commercial coherence, the fact that activities may be conducted within a limited geographic area should not result in that area being considered a fixed place of business. A place of business. This refers to some facilities used by an enterprise for carrying out its business. The premises must be at the disposal of the enterprise. The mere presence of the enterprise at that place does not necessarily mean that it is a place of business of the enterprise. The facilities need not be the exclusive location, and they need not be used exclusively by that enterprise or for that business. However, the facilities must be those of the taxpayer, not another unrelated person. Thus, regular use of a customer's premises does not generally constitute a place of business. Business of the enterprise must be carried on wholly or partly at the fixed place. The requirements of what constitutes a PE within the scope of a particular treaty depend on what interpretation a particular country places on that term, in context of the text of that treaty. As per Article 3 of the Vienna Convention on the Law of Treaties, no one is entitled to claim rights under a particular treaty unless otherwise authorised by the contracting state. Therefore, if a particular contracting state places a different meaning on the term 'permanent establishment' than what the taxpayer seeks to place, the taxpayer would be left with virtually no remedy within that state, other than to seek a mutual agreement to that dispute with the other contracting state to that treaty. Indicative list of permanent establishments The OECD Model Tax Convention includes a short indicative list of prima facie PEs. These, however, are not automatically PEs as the requirements set out, namely, for a fixed place of business PE must be met. The list is as follows: A branch A warehouse (but see excluded places below) A factory A mine or place of extraction of natural resources A place of management Specifically excluded places Many treaties explicitly exclude from the definition of PE places if certain
