(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 Contracting State the tax so charged shall not exceed 5 per cent of the gross amount of the interest.
(3) Notwithstanding the provisions of paragraphs (1) and (2), interest paid by a company which is a resident of a Contracting State shall be taxable only in the other Contracting State if the beneficial owner of the interest is that other State itself, a political subdivision or local authority thereof or a financial institution which is a resident of the other Contracting State.
(4) 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" shall not include for the purpose of this Article penalty charges for late payment nor interest regarded as dividends under paragraph (5) of Article 10 or regarded as profits under sub-paragraph (c) of paragraph (2) of Article 8.
(5) The provisions of paragraphs (1), (2) and (3) 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 such permanent establishment or fixed base. In such case the provisions of Article 7 or Article 14, as the case may be, shall apply.
(6) 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 paving 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.
(7) 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 the Contracting State in which the interest arises according to the laws of that State.
