CONCERNING GENERAL DEFINITIONS 1. This Article groups together a number of general provisions required for the interpretation of the terms used in the Convention. The meaning of some important terms, however, is explained elsewhere in the Convention. Thus, the terms "resident" and "permanent establishment" are defined in Articles 4 and 5 respectively, while the interpretation of certain terms appearing in the Articles on special categories of income ("income from immovable property", "dividends", etc.) is clarified by provisions embodied in those Articles. In addition to the definitions contained in the Article, Contracting States are free to agree bilaterally on definitions of the terms "a Contracting State" and "the other Contracting State". Furthermore, Contracting States are free to agree bilaterally to include in the possible definitions of "Contracting States" a reference to continental shelves. Paragraph 1 THE TERM "PERSON" 2. The definition of the term "person" given in subparagraph a) is not exhaustive and should be read as indicating that the term "person" is used in a very wide sense (cf. especially Articles 1 and 4). The definition explicitly mentions individuals, companies and other bodies of persons. From the meaning assigned to the term "company" by the definition contained in subparagraph b) it follows that, in addition, the term "person" includes any entity that, although not incorporated, is treated as a body corporate for tax purposes. Thus, e.g. a foundation (fondation, Stiftung) may fall within the meaning of the term "person". Partnerships will also be considered to be "persons" either because they fall within the definition of "company" or, where this is not the case, because they constitute other bodies of persons. THE TERM "COMPANY" 3. The term "company" means in the first place any body corporate. In addition, the term covers any other taxable unit that is treated as a body corporate according to the tax laws of the Contracting State in which it is organised. The definition is drafted with special regard to the Article on dividends. The term "company" has a bearing only on that Article, paragraph 7 of Article 5, and Article 16. THE TERM "ENTERPRISE" 4. The question whether an activity is performed within an enterprise or is deemed to constitute in itself an enterprise has always been interpreted according to the provisions of the domestic laws of the Contracting States. No exhaustive definition of the term OECD 72
"enterprise" has therefore been attempted in this Article. However, it is provided that the term "enterprise" applies to the carrying on of any business. Since the term "business" is expressly defined to include the performance of professional services and of other activities of an independent character, this clarifies that the performance of professional services or other activities of an independent character must be considered to constitute an enterprise, regardless of the meaning of that term under domestic law. States which consider that such clarification is unnecessary are free to omit the definition of the term "enterprise" from their bilateral conventions. THE TERM "INTERNATIONAL TRAFFIC" 5. The definition of the term "international traffic" is based on the principle set forth in paragraph 1 of Article 8 that the right to tax profits from the operation of ships or aircraft in international traffic resides only in the Contracting State in which the place of effective management is situated in view of the special nature of the international traffic business. However, as stated in the Commentary on paragraph 1 of Article 8, the Contracting States are free on a bilateral basis to insert in subparagraph d) a reference to residence, in order to be consistent with the general pattern of the other Articles. In such a case, the words "an enterprise that has its place of effective management in a Contracting State" should be replaced by "an enterprise of a Contracting State" or "a resident of a Contracting State". 6. The definition of the term "international traffic" is broader than is normally understood. The broader definition is intended to preserve for the State of the place of effective management the right to tax purely domestic traffic as well as international traffic between third States, and to allow the other Contracting State to tax traffic solely within its borders. This intention may be clarified by the following illustration. Suppose an enterprise of a Contracting State or an enterprise that has its place of effective management in a Contracting State, through an agent in the other Contracting State, sells tickets for a passage that is confined wholly within the first-mentioned State or alternatively, within a third State. The Article does not permit the other State to tax the profits of either voyage. The other State is allowed to tax such an enterprise of the first-mentioned State only where the operations are confined solely to places in that other State. 6.1 A ship or aircraft is operated solely between places in the other Contracting State in relation to a particular voyage if the place of departure and the place of arrival of the ship or aircraft are both in that other Contracting State. However, the definition applies where the journey of a ship or aircraft between places in the other Contracting State forms part of a longer voyage of that ship or aircraft involving a place of departure or a place of arrival which is outside that other Contracting State. For example, where, as part of the same voyage, an aircraft first flies between a place in one Contracting State to a place in the other Contracting State and then continues to another destination also located in that other Contracting State, the first and second legs of that trip will both be part of a voyage regarded as falling within the definition of "international traffic". OECD 73
OECD MODEL TAX CONVENTION 6.2 Some States take the view that the definition of "international traffic" should rather refer to a transport as being the journey of a passenger or cargo so that any voyage of a passenger or cargo solely between two places in the same Contracting State should not be considered as covered by the definition even if that voyage is made on a ship or plane that is used for a voyage in international traffic. Contracting States having that view may agree bilaterally to delete the reference to "the ship or aircraft" in the exception included in the definition, so as to use the following definition: "e) the term "international traffic" means any transport by a ship or aircraft operated by an enterprise that has its place of effective management in a Contracting State, except when such transport is solely between places in the other Contracting State;" 6.3 The definition of "international traffic" does not apply to a transport by an enterprise which has its place of effective management in one Contracting State when the ship or aircraft is operated between two places in the other State, even if part of the transport takes place outside that State. Thus, for example, a cruise beginning and ending in that other State without a stop in a foreign port does not constitute a transport of passengers in international traffic. Contracting States wishing to expressly clarify that point in their conventions may agree bilaterally to amend the definition accordingly. THE TERM "COMPETENT AUTHORITY" 7. The definition of the term "competent authority" recognizes that in some OECD Member countries the execution of double taxation conventions does not exclusively fall within the competence of the highest tax authorities; some matters are reserved or may be delegated to other authorities. The present definition enables each Contracting State to designate one or more authorities as being competent. THE TERM "NATIONAL" 8. The definition of the term "national" merely stipulates that, in relation to a Contracting State, the term applies to any individual possessing the nationality or citizenship of that Contracting State. Whilst the concept of nationality covers citizenship, the latter term was also included in 2002 because it is more frequently used in some States. It was not judged necessary to include in the text of the Convention any more precise definition of the terms nationality and citizenship, nor did it seem indispensable to make any special comment on the meaning and application of these words. Obviously, in determining what is meant by "national" in the case of an individual, reference must be made to the sense in which the term is usually employed and each State s particular rules on the acquisition or loss of nationality or citizenship. 9. Subparagraph g) is more specific as to legal persons, partnerships and associations. By declaring that any legal person, partnership or association deriving its status as such 74 OECD
from the laws in force in a Contracting State is considered to be a national, the provision disposes of a difficulty that often arises. In defining the nationality of companies, certain States have regard less to the law that governs the company than to the origin of the capital with which the company was formed or the nationality of the individuals or legal persons controlling it. 10. Moreover, in view of the legal relationship created between a company and the State under whose law it is organised, which from certain points of view is closely akin to the relationship of nationality in the case of individuals, it seems justifiable not to deal with legal persons, partnerships and associations in a special provision, but to assimilate them with individuals under the term "national". 10.1 The separate mention of partnerships in subparagraph 1 g) is not inconsistent with the status of a partnership as a person under subparagraph 1 a). Under the domestic laws of some countries, it is possible for an entity to be a "person" but not a "legal person" for tax purposes. The explicit statement is necessary to avoid confusion. THE TERM "BUSINESS" 10.2 The Convention does not contain an exhaustive definition of the term "business", which, under paragraph 2, should generally have the meaning which it has under the domestic law of the State that applies the Convention. Subparagraph h), however, provides expressly that the term includes the performance of professional services and of other activities of an independent character. This provision was added in 2000 at the same time as Article 14, which dealt with Independent Personal Services, was deleted from the Convention. This addition, which ensures that the term "business" includes the performance of the activities which were previously covered by Article 14, was intended to prevent that the term "business" be interpreted in a restricted way so as to exclude the performance of professional services, or other activities of an independent character, in States where the domestic law does not consider that the performance of such services or activities can constitute a business. Contracting States for which this is not the case are free to agree bilaterally to omit the definition. Paragraph 2 11. This paragraph provides a general rule of interpretation for terms used in the Convention but not defined therein. However, the question arises which legislation must be referred to in order to determine the meaning of terms not defined in the Convention, the choice being between the legislation in force when the Convention was signed or that in force when the Convention is being applied, i.e. when the tax is imposed. The Committee on Fiscal Affairs concluded that the latter interpretation should prevail, and in 1995 amended the Model to make this point explicitly. OECD 75
OECD MODEL TAX CONVENTION 12. However, paragraph 2 specifies that this applies only if the context does not require an alternative interpretation. The context is determined in particular by the intention of the Contracting States when signing the Convention as well as the meaning given to the term in question in the legislation of the other Contracting State (an implicit reference to the principle of reciprocity on which the Convention is based). The wording of the Article therefore allows the competent authorities some leeway. 13. Consequently, the wording of paragraph 2 provides a satisfactory balance between, on the one hand, the need to ensure the permanency of commitments entered into by States when signing a convention (since a State should not be allowed to make a convention partially inoperative by amending afterwards in its domestic law the scope of terms not defined in the Convention) and, on the other hand, the need to be able to apply the Convention in a convenient and practical way over time (the need to refer to outdated concepts should be avoided). 13.1 Paragraph 2 was amended in 1995 to conform its text more closely to the general and consistent understanding of Member states. For purposes of paragraph 2, the meaning of any term not defined in the Convention may be ascertained by reference to the meaning it has for the purpose of any relevant provision of the domestic law of a Contracting State, whether or not a tax law. However, where a term is defined differently for the purposes of different laws of a Contracting State, the meaning given to that term for purposes of the laws imposing the taxes to which the Convention applies shall prevail over all others, including those given for the purposes of other tax laws. States that are able to enter into mutual agreements (under the provisions of Article 25 and, in particular, paragraph 3 thereof) that establish the meanings of terms not defined in the Convention should take those agreements into account in interpreting those terms. Reservations on the Article 14. Italy and Portugal reserve the right not to include the definitions in subparagraphs 1 c) and h) ("enterprise" and "business") because they reserve the right to include an article concerning the taxation of independent personal services. 15. Mexico and the United States reserve the right to omit the phrase operated by an enterprise that has its place of effective management in a Contracting State from the definition of international traffic in subparagraph e) of paragraph 1. 76 OECD
