ARTICLE 21
PROFESSORS, TEACHERS AND RESEARCHERS 1. An individual who is a resident of a Contracting State immediately before making a visit to the other Contracting State, and who, at the invitation of any university, college, school or other similar educational institution which is recognized by the competent authority in that other Contracting State, visits that other contracting State for a period not exceeding two years solely for the purpose of teaching or research or both at such educational institution shall be exempt from tax in that other Contracting State on any remuneration for such teaching or research. 2. This Article shall only apply to income from research if such research is undertaken by the individual for the public interest and not primarily for the benefit of some other private person or persons. ARTICLE 22 INCOME NOT EXPRESSLY MENTIONED Items of income of a resident of a Contracting State which are not expressly mentioned in the foregoing Articles of this Agreement may be taxed in the State where the income arises. ARTICLE 23
METHOD FOR ELIMINATION OF DOUBLE TAXATION 1. Where a resident of a Contracting State derives income which, in accordance with the provisions of this Agreement, may be taxed in the other Contracting State, the first-mentioned State shall allow as deduction from the tax on the income of that resident an amount equal to the income tax paid in that other State. Such deduction shall not, however, exceed that part of the income tax as computed before the deduction is given, which is attributable, as the case may be, to the income which may be taxed in that other State. 2. For the purposes of paragraph 1 of this Article, the term "tax paid in that other State" shall be deemed to include the amount of tax which would have been paid in that other State if it had not been exempted or reduced in accordance with the special incentive laws designed to promote economic development in that other State, effective on the date of signature of this Agreement or which may be introduced hereafter in modification of, or in addition to, the existing laws. ARTICLE 24
NON - DISCRIMINATION 1. Nationals of a Contracting State shall not be subjected in the other Contracting State to any taxation or any requirement connected therewith which is other or more burdensome than the taxation and connected requirements to which nationals of that other State in the same circumstances are or may be subjected. This provision shall, notwithstanding the provisions of Article 1, also apply to persons who are not residents of one or both of the Contracting States. 2. The taxation on a permanent establishment which an enterprise of a Contracting State has in the other Contracting State shall not be less favourably levied in that other State than the taxation levied on enterprises of that other State carrying on the same activities. 3. Enterprises of a Contracting State, the capital of which is wholly or partly owned or controlled, directly or indirectly, by one or more residents of the other Contracting State, shall not be subjected in the first-mentioned State to any taxation or any requirement connected therewith which is other or more burdensome than the taxation and connected requirements to which other similar enterprises of the first-mentioned State are or may be subjected. 4. The provisions of this Article shall not be construed as obliging a Contracting State to grant to residents of the other Contracting State any personal allowances, reliefs and reductions for taxation purposes on account of civil status or family responsibilities which it grants to its own residents. 5. In this Article the term "taxation" means taxes which are the subject of this Agreement. ARTICLE 25
MUTUAL AGREEMENT PROCEDURE 1. 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 Agreement, he may, irrespective of the remedies provided by the domestic laws of those States, present his case to the competent authority of the Contracting State of which he is a resident or, if his case comes under paragraph 1 of Article 24, to that of the Contracting State of which he is a national. The case must be presented within two years from the first notification of the action resulting in taxation not in accordance with the provisions of the Agreement. 2. The competent authority shall endeavour, 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 this Agreement. 3. The competent authorities of the Contracting States shall endeavour to resolve by mutual agreement any difficulties or doubts arising as to the interpretation or application of the Agreement. They may also consult together for the elimination of double taxation in cases not provided for in the Agreement. 4. The competent authorities of the Contracting States may communicate with each other directly for the purposes of reaching an agreement in the sense of the preceding paragraphs. |
