(1) 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. In such case, the business profits of the enterprise may be taxed in the other State but only so much of them as are attributable to: (a) that permanent establishment; or (b) sales in that other State of goods or merchandise of the same or similar kind as those sold through that permanent establishment; or (c) other business activities carried on in that other State of the same or similar kind as those effected through 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 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 determining the profits of a permanent establishment, there shall be allowed as deductions expenses including executive and general administrative expenses, insofar as they are incurred for the purposes of the permanent establishment, whether incurred in the State in which the permanent establishment is situated or elsewhere, only if the domestic legislation of the Contracting State where the establishment is located, consider such expenses as deductible.
The Contracting State where the permanent establishment is located shall recognize its expenses if it complies with the formal requirements set out in the domestic laws of that Contracting State.
(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) 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.
(6) Where profits include items of income which are dealt with separately in other Articles of this Agreement, then the provisions of those Articles shall not be affected by the provisions of this Article.
