(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% 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 paragraphs (1) and (2) of this Article, the interest arising from a Contracting State shall be taxable only in that other Contracting State if the beneficial owner of interest is the other Contracting State, a local authority thereof or it's Central Bank.
(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. However, in the case of Luxembourg, the term ‘interest’ does not include income dealt with in Article 10. Penalty charges for late payment shall not be regarded as interest for the purpose of this Article.
(5) The provisions of paragraphs (1) and (2) of this Article shall not apply if the beneficial owner of the interest, being a resident of a Contracting State, carries on an industrial or commercial activity 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 of this Convention, as the case may be, 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 or a fixed base in connection with which the liability to pay the interest was incurred, and such interests are borne by such permanent establishment or fixed base, then such interest shall be deemed to arise in the Contracting 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 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 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.
