(1) Interest arising in a Contracting State and paid to a resident of the other Contracting State may be taxed in the State in which it arises and according to its laws.
(2) The term "interest" as used in this Article means income from government securities, bonds or debentures, whether or not secured by mortgage and whether or not carrying a clause establishing the right to participate in the profits, and debt-claims of every nature, as well as all other income assimilated to income from loan amounts, under the taxation laws of the State of the payer.
(3) Interest shall be deemed to arise in a Contracting State when the payer is that State itself, an administrative or political subdivision, a local authority or another resident of that State.
Where, however, the person paying the interest, whether he or she 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.
(4) Where, by reason of a special relationship between the payer and the beneficial owner or between both of them and some third parties, 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 a similar 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 each Contracting State, due regard being had to the other provisions of this Convention.
