3 - In determining the profits of a permanent establishment, there shall be allowed as deductions expenses which are incurred for the purposes of the business of the permanent establishment, including executive and general administrative expenses so incurred, whether in the State in which the permanent establishment is situated or elsewhere. However, no such deduction shall be allowed in respect of amounts, if any, paid (otherwise than towards reimbursement of actual expenses) by the permanent establishment to the head office of the enterprise or any of its other offices, by way of royalties, fees or other similar payments in return for the use of patents or other rights, or by way of commission, for specific services performed or for management, or, except in the case of a banking enterprise, by way of interest on moneys lent to the permanent establishment. Likewise, no account shall be taken, in the determination of the profits of a permanent establishment, for amounts charged (otherwise than towards reimbursement of actual expenses), by the permanent establishment to the head office of the enterprise or any of its other offices, by way of royalties, fees or other similar payments in return for the use of patents or other rights, or by way of commission for specific services performed or for management, or, except in the case of banking enterprise by way of interest on moneys lent to the head office of the enterprise or any of its other offices.

4 - Insofar as it has been customary in a Contracting State to determine the profits to be attributed to a permanent establishment on the basis of an apportionment of the total profits of the enterprise to its various parts, nothing in paragraph 2 shall preclude that Contracting State from determining the profits to be taxed by such an apportionment as may be customary; the method of apportionment adopted shall, however, be such that the result shall be in accordance with the principles contained in this article.

5 - No profits shall be attributed to a permanent establishment by reason of the mere purchase by that permanent establishment of goods or merchandise in order to continue production or processing by the enterprise.

6 - For the purposes of the preceding paragraphs, the profits to be attributed to the permanent establishment shall be determined by the same method year by year unless there is good and sufficient reason to the contrary.

7 - Where profits include items of income which are dealt with separately in other articles of this Agreement, then the provisions of those articles shall not be affected by the provisions of this article.

Article 8

Shipping and air transport

1 - Profits derived by an enterprise of a Contracting State from the operation of ships or aircraft in international traffic shall be taxable only in that Contracting State.

Article 9

Associated enterprises

1 - Where:

(a) An enterprise of a Contracting State participates directly or indirectly in the management, control or capital of an enterprise of the other Contracting State; or

(b) The same persons participate directly or indirectly in the management, control or capital of an enterprise of a Contracting State and an enterprise of the other Contracting State;

and in either case conditions are made or imposed between the two enterprises in their commercial or financial relations which differ from those which would be made between independent enterprises, then any profits which would, but for those conditions, have accrued to one of the enterprises, but, by the reason of those conditions, have not so accrued, may be included in the profits of that enterprise and taxed accordingly.

2 - Where a Contracting State includes in the profits of an enterprise of that State - and taxes accordingly - profits on which an enterprise of the other Contracting State has been charged to tax in that other State and the profits so included are profits which would have accrued to the enterprise of the first-mentioned State if the conditions made between the two enterprises had been those which would have been made between independent enterprises, then that other State, if it agrees that the adjustment made by the first-mentioned State is justified both in principle and as regards the amount, shall make an appropriate adjustment to the amount of the tax charged therein on those profits. In determining such adjustment, due regard shall be had to the other provisions of this Agreement and the competent authorities of the Contracting States shall if necessary consult each other.

Article 10

Dividends

(a) 5 per cent of the gross amount of the dividends if the recipient is a company (excluding partnerships) which owns directly at least 70 per cent of the capital of the company paying the dividends;

(b) 10 per cent of the gross amount of the dividends if the recipient is a company (excluding partnerships) which owns directly at least 25 per cent of the capital of the company paying the dividends;

(c) 15 per cent of the gross amount of the dividends in all other cases.

This paragraph shall not affect the taxation of the company in respect of the profits out of which the dividends are paid.

3 - The term "dividends" as used in this Article means income from shares, "jouissance" shares or "jouissance" rights, mining shares, founders' shares or other rights, not being debt-claims, participating in profits, as well as income from other corporate rights or other income which is subjected to the same taxation treatment as income from shares by the laws of the State of which the company making the distribution is a resident.

4 - The provisions of paragraphs 1 and 2 shall not apply if the beneficial owner of the dividends, being a resident of a Contracting State, carries on business in the other Contracting State of which the company paying the dividends is a resident, through a permanent establishment situated therein, or performs in that other Contracting State independent personal services from a fixed base situated therein, and the holding in respect of which the dividends are paid is effectively connected with such permanent establishment or fixed base. In such case the provisions of article 7 or article 14, as the case may be, shall apply.

5 - Where a company which is a resident of a Contracting State derives profits or income from the other Contracting State, that other Contracting State may not impose any tax on the dividends paid by the company, except insofar as such dividends are paid to a resident of that other Contracting State or insofar as the holding in respect of which the dividends are paid is effectively connected with a permanent establishment or a fixed base situated in that other Contracting State, nor subject the company's undistributed profits to a tax on the company's undistributed profits, even if the dividends paid or the undistributed profits consist wholly or partly of profits or income arising in such other Contracting State.

3 - Notwithstanding the provisions of paragraph 2, interest referred to in paragraph 1 shall be taxable only in the Contracting State of which the recipient is a resident, if such interest is paid to and beneficially owned by:

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 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, or performs in that other Contracting 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, 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 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.

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, 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 Agreement.

Article 12

Royalties and technical fees

1 - Royalties and technical fees arising in a Contracting State and paid to a resident of the other Contracting State may be taxed in that other Contracting State.

In such case the provisions of article 7 or article 14, as the case may be, shall apply.

(b) Where in accordance with any provisions of the Agreement income derived by a resident of Portugal is exempt from tax in Portugal, Portugal may nevertheless, in calculating the amount of tax on the remaining income of such resident, take into account the exempted income;

Article 23

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 Contracting State in the same circumstances, in particular with respect to residence, are or may be subjected.

The case must be presented within three 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.

4 - If information is requested by a Contracting State in accordance with this Article, the other Contracting State shall use its information gathering measures to obtain the requested information, even though that other State may not need such information for its own tax purposes. The obligation contained in the preceding sentence is subject to the limitations of paragraph 3 but in no case shall such limitations be construed to permit a Contracting State to decline to supply information solely because it has no domestic interest in such information.

5 - In no case shall the provisions of paragraph 3 be construed to permit a Contracting State to decline to supply information solely because the information is held by a bank, other financial institution, nominee or person acting in an agency or a fiduciary capacity or because it relates to ownership interest in a person.
