DT: Tunisia: double taxation agreement, 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) 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 incurred for the purposes of the business of the permanent establishment, including management expenses and general administrative expenses so incurred, whether in the State in which the permanent establishment is situated or elsewhere. No deduction shall be allowed for sums which are paid (other than the reimbursement of expenses actually incurred) by the permanent establishment to the head office or to any other office of the enterprise as royalties, fees or other similar payments in respect of the use of licences, patents or other rights, as commission for services rendered or for management or, except in the case of a banking enterprise, as interest on sums loaned to the permanent establishment.
(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) of this Article 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 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.
(7) The provisions of this Article shall apply to the profits derived by a resident of the United Kingdom in Tunisia in respect of his participation in a joint venture (association en participation) or a partnership (societe de fait) with a Tunisian enterprise or Tunisian enterprises.
(8) 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.
