Mutual Agreement Procedure
Where a person considers that the actions of one or both of the Contracting States result or will result for him in taxation not in accordance with the provisions of this Convention, he may, irrespective of the remedies provided by the domestic law of those States, present his case in writing to the competent authority of the Contracting State of which he is a resident or, if he is a resident of neither Contracting State, or which he is a national.
The competent authority of the Contracting State to which the case has been presented shall endeavor, if the objection appears to it to be justified and if it is not itself able to arrive at a satisfactory solution, to resolve the case by mutual agreement with the competent authority of the other Contracting State, with a view to the avoidance of taxation which is not in accordance with the Convention. Except where the provisions of Article IX (Related Persons) apply, any agreement reached shall be implemented notwithstanding any time or other procedural limitations in the domestic law of the Contracting States, provided that the competent authority of the other Contracting State has received notification that such a case exists within six years from the end of the taxable year to which the case relates.
The competent authorities of the Contracting States shall endeavor to resolve by mutual agreement any difficulties or doubts arising as to the interpretation or application of the Convention. In particular, the competent authorities of the Contracting States may agree:
(a) To the same attribution of profits to a resident of a Contracting State and its permanent establishment situated in the other Contracting State;
(b) To the same allocation of income, deductions, credits or allowances between persons;
(c) To the same determination of the source, and the same characterization, of particular items of income;
(d) To a common meaning of any term used in the Convention; (e) To the elimination of double taxation with respect to income distribution by an estate or trust;
(f) To the elimination of double taxation with respect to a partnership; or
(g) To increases in any other amounts referred to in the Convention to reflect monetary or economic developments. They may also consult together for the elimination of double taxation in cases not provided for in the Convention.
Each of the Contracting States will endeavor to collect on behalf of the other Contracting State such amounts as may be necessary to ensure that relief granted by the Convention from taxation imposed by that other State does not enure to the benefit of persons not entitled thereto. However, nothing in this paragraph shall be construed as imposing on either of the Contracting States the obligation to carry out administrative measures of a different nature from those used in the collection of its own tax or which would be contrary to its public policy (ordre public).
The competent authorities of the Contracting States may communicate with each other directly for the purpose of reaching an agreement in the sense of the proceeding paragraphs.
