(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) of this Article, 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 which 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 the determination of the. profits of a permanent establishment, there shall be allowed as deductions expenses which are incurred for the purposes of the business of the permanent establishment including executive and general administrative expenses so incurred, whether in the State in which the permanent establishment is situated or elsewhere. However, no such deduction shall be allowed in respect of amounts, if any, paid (otherwise than, towards reimbursement of actual expenses) by the permanent establishment to the head office of the enterprise or any of its other offices, by way of royalties, fees or other similar payments in return for the use of patents or other rights, or by way of commission, for specific services performed or for management, or, except in the case of a banking enterprise, by way of income from debt-claim with regard to moneys lent to the permanent establishment. Likewise, no account shall be taken, in the determination of the profits of a permanent establishment, for amounts charged (otherwise than towards reimbursement of actual expenses), by the permanent establishment to the head office of the enterprise or any of its other offices, by way of royalties, fees or other similar payments in return for the use of patents or other rights, or by way of commission for specific services performed or for management, or, except in the case of a banking enterprise, by way of income from debt-claim with regard to moneys lent to the head office of the enterprise or any of its other offices.
(4) 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) The profits derived by an enterprise of a Contracting State from the exportation of merchandise to the other Contracting State shall not be taxed in that other Contracting State. Where export contracts include other activities carried on through a permanent establishment in the other Contracting State, profits derived from such activities may be taxed in the other Contracting State.
(6) 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.
(7) For the purposes of the preceding paragraphs, the profits to be attributed to the permanent establishment shall be determined by the same method year by year unless there is good and sufficient reason to the contrary.
(8) The term "business profits" includes, but is not limited to, profits derived from manufacturing, mercantile, banking, insurance, from the operation of inland transportation and the furnishing of services. Such term does not include profits from the performance of personal services by an individual either as an employee or in an independent capacity.
(9) Nothing in this Article shall affect the operation of any law of a Contracting State relating to tax imposed on income derived by nonresidents from insurance activities.
(10) Where profits include items of income which are dealt with separately in other Articles of this Convention, then the provisions of those Articles shall not be affected by the provisions of this Article.
