ARTICLE 7 — U.S. Income Tax Treaty

Business Profits

The income or 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 income or profits of the enterprise may be taxed in the other State but only so much of them as is attributable to:

a) that permanent establishment; 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.

The provisions of subparagraphs (b) and (c) shall apply only if it can be shown that the sales or activities were not carried out by the permanent establishment in order to avoid tax in the Contracting State in which the permanent establishment is situated.

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 income or profits which it might be expected to make if it were a distinct and independent enterprise engaged in the same or similar activities under the same or similar conditions.
In determining the income or profits of a permanent establishment, there shall be allowed as deductions expenses which are incurred for the purposes of the permanent establishment, including a reasonable allocation or apportionment of executive and general administrative expenses so incurred, whether in the State in which the permanent establishment is situated or elsewhere.
Insofar as it has been customary in a Contracting State to determine the income or 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 or, in the case of a person who does not claim taxation on the basis of the actual net profits of the permanent establishment, on the basis of a certain reasonable percentage of the gross receipts of the permanent establishment, nothing in paragraph 2 of this Article shall preclude such State from determining the income or profits to be taxed by such a method. The method adopted shall, however, be such that the result shall be in accordance with the principles laid down in this Article.
No income or 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.
For the purposes of the preceding paragraphs, the income or 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.
Where income or 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.
For the purposes of the Convention, the term "business profits" means income derived from any trade or business, including profits from the rental of ships, aircraft and containers (including trailers, barges and related equipment for the transport or containers), if such profits are not incidental to income from the operation of ships or aircraft in international traffic.
In applying paragraphs 1 and 2 of this Article, paragraph 5 of Article 10 (Dividends), paragraph 5 of Article 11 (Interest), paragraph 4 of Article 12 (Royalties), paragraph 1(a) of Article 15 (Independent Personal Services) and paragraph 2 of Article 24 (Other Income), any income attributable to a permanent establishment or fixed base during its existence is taxable in the Contracting State in which such permanent establishment or fixed base is situated, even if the payments are deferred until such permanent establishment or fixed base has ceased to exist.
