ARTICLE 7
Business Profits
1. The profits of an enterprise of a Contracting State shall be taxable only in that State unless the enterprise carries on business in the other Contracting State through a permanent establishment situated therein. If the enterprise carries on business as aforesaid, the profits of the enterprise may be taxed in the other State but only so much of them as is attributable to that permanent establishment.
2. Subject to the provisions of paragraph 3, where an enterprise of a Contracting State carries on business in the other Contracting State through a permanent establishment situated therein, there shall in each Contracting State be attributed to that permanent establishment the profits that it might be expected to make if it were a distinct and separate enterprise engaged in the same or similar activities under the same or similar conditions and dealing wholly independently with the enterprise of which it is a permanent establishment.
3. In determining the profits of a permanent establishment, there shall be allowed as deductions expenses that are incurred for the purposes of the permanent establishment, including a reasonable allocation of executive and general administrative expenses, research and development expenses, interest, and other expenses incurred for the purposes of the enterprise as a whole (or the part thereof which includes the permanent establishment), whether incurred in the State in which the permanent establishment is situated or elsewhere.
4. Notwithstanding paragraph 6 below, insofar as it has been customary in a Contracting State to determine the profits to be attributed to a permanent establishment on the basis of an apportionment of the total profits of the enterprise to its various parts, nothing in paragraph 2 shall preclude that Contracting State from determining the profits to be taxed by such an apportionment as may be customary; the method of apportionment adopted shall, however, be such that the result shall be in accordance with the principles contained in this Article.
5. No profits shall be attributed to a permanent establishment by reason of the mere purchase by that permanent establishment of goods or merchandise for the enterprise.
6. For the purposes of this Article, the profits to be attributed to the permanent establishment shall include only the profits derived from the assets or activities of the permanent establishment and shall be determined by the same method of accounting year by year unless there is good and sufficient reason to the contrary.
7. The term "profits" as used in this Article includes income from the performance of personal services by an enterprise and income from the rental of tangible movable property.
8. Where profits include items of income that are dealt with separately in other Articles of the Convention, then the provisions of those Articles shall not be affected by the provisions of this Article.
