(1) Interest arising in a Contracting State and paid to a resident of the other Contracting State may be taxed in that other State.
(2) However, such interest may also be taxed in the Contracting State in which it arises and according to the laws of that State, but if the beneficial owner of the interest is a resident of the other State, the tax so charged shall not exceed 15 per cent of the gross amount of the interest. Notwithstanding the preceding paragraph, the tax paid in Senegal shall not exceed 16 per cent of the gross amount of the interest insofar as tax on income from movable property applicable to interest paid to non-residents is 16 per cent in accordance with the laws of Senegal.
(3) The term "interest" as used in this Article means income from debt-claims of every kind, whether or not secured by mortgage and whether or not carrying a right to participate in the debtor's profits, and in particular, income from government securities and income from bonds or debentures, including premiums and prizes attaching to such securities, bonds or debentures; however, the term "interest" does not include, within the meaning of this Article, penalties for late payments nor interest treated as dividends under Article 10, paragraph (3), sub-paragraph (b).
(4) The provisions of paragraphs (1) and (2) shall not apply if the beneficial owner of the interest, being a resident of a Contracting State, carries on business in the other Contracting State in which the interest arises, through a permanent establishment situated therein, or performs in that other State independent personal services from a fixed base situated therein, and the debt-claim in respect of which the interest is paid is effectively connected with it. In such case, the provisions of Article 7 or Article 14, as the case may be, shall apply.
(5) Interest shall be deemed to arise in a Contracting State when the payer is that State itself, a political subdivision, a local authority or a resident of that State. Where, however, the person paying the interest, whether he is a resident of a Contracting State or not, has in a Contracting State a permanent establishment or a fixed base in connection with which the indebtedness on which the interest is paid was incurred, and such interest is borne by such permanent establishment or fixed base, then such interest shall be deemed to arise in the State in which the permanent establishment or fixed base is situated.
(6) Where by reason of a special relationship between the payer and the beneficial owner or between both of them and some other person, the amount of the interest, having regard to the debt-claim for which it is paid, exceeds the amount which would have been agreed upon by the payer and the beneficial owner in the absence of such relationship, the provisions of this Article shall apply only to the last-mentioned amount. In such case, the excess part of the payments shall remain taxable, in accordance with the laws of the Contracting State in which the interest arises.
