(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 10 percent of the gross amount of the interest. The competent authorities of the Contracting States shall by mutual agreement settle the mode of application of this limitation.
(3) Notwithstanding the provisions of paragraph 2, the Government of a Contracting State, its political subdivisions and local authorities shall be exempt from tax in the other Contracting State in respect of interest derived from that 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 attaching to such securities, bonds or debentures. Penalty charges for late payment shall not be regarded as interest for the purpose of this Article. The term shall not include any item which is treated as a dividend under the provisions of Article 10.
(5) 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 and the debt-claim in respect of which the interest is paid is effectively connected with such permanent establishment. In such case the provisions of Article 7 shall apply.
(6) Interest shall be deemed to arise in a Contracting State when the payer is 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 in connection with which the indebtedness on which the interest is paid was incurred, and such interest is borne by such permanent establishment, then such interest shall be deemed to arise in the State in which the permanent establishment 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 paid exceeds, for whatever reason, 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 according to the laws of each Contracting State, due regard being had to the other provisions of this Convention.
(8) No relief shall be available under this Article if it was the main purpose or one of the main purposes of any person concerned with the creation or assignment of the debt-claim in respect of which the interest is paid to take advantage of this Article by means of that creation or assignment.
