8. The fact that a company which is a resident of a Contracting State controls or is controlled by a company which is a resident of the other Contracting State, or which carries on business in that other State (whether through a permanent establishment or otherwise), shall not of itself constitute either company a permanent establishment of the other.

Article 7
Business profits
1. The profits of an enterprise of a Contracting State shall be taxable only in that State unless the enterprise carries on business in the other Contracting State through a permanent establishment situated therein. If the enterprise carries on business as aforesaid, the profits of the enterprise may be taxed in the other State, but only so much of them as is attributable to that permanent establishment.
2. Subject to the provisions of paragraph 3, where an enterprise of a Contracting State carries on business in the other Contracting State through a permanent establishment situated therein, there shall in each Contracting State be attributed to that permanent establishment the profits which it might be expected to make if it were a distinct and separate enterprise engaged in the same or similar activities under the same or similar conditions and dealing wholly independently with the enterprise of which it is a permanent establishment.
3. In determining the profits of a permanent establishment, there shall be allowed as deductions expenses which are incurred for the purposes 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.
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 for 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 Convention, then the provisions of those Articles shall not be affected by the provisions of this Article.
Article 8

3. The provisions of paragraph 1 shall also apply to profits from the participation in a pool, a joint business or an international operating agency.
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 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 shall make an appropriate adjustment to the amount of the tax charged therein on those profits, where that other State considers the adjustment justified. In determining such adjustment, due regard shall be had to the other provisions of this Convention and the competent authorities of the Contracting States shall, if necessary, consult each other.
Article 10
Dividends
1. Dividends paid by a company which is a resident of a Contracting State to a resident of the other Contracting State may be taxed in that other State.
2. However, such dividends may also be taxed in the Contracting State of which the company paying the dividends is a resident and according to the laws of that State but, if the recipient is the beneficial owner of the dividends, the tax so charged shall not exceed 15% of the gross amount of the dividends.
The competent authorities of the Contracting States shall by mutual agreement settle the mode of application of these limitations.
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 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. The term “dividends” shall also include, in the case of Portugal, profits paid under a profit-sharing arrangement (associaçâo em participaçâo) and, in the case of Luxembourg, income derived by a sleeping partner from his participation in profits of a business enterprise.
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 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 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 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 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 State.
Article 11
Interest
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 recipient is the beneficial owner of the interest, the tax so charged shall not exceed:
(a) 10% of the gross amount of the interest, if the interest is paid by an enterprise of a Contracting State, for which such interest is deemed to be a deductible expense, to a financial establishment which is a resident of the other Contracting State;
(b) 15% of the gross amount of the interest, in all other cases.
The competent authorities of the Contracting States shall by mutual agreement settle the mode of application of these limitations.
3. The term “interest” as used in this Article means income from government securities and income from bonds or debentures, whether or not secured by mortgage and whether or not carrying a right to participate in the debtor’s profits, and income from other debt-claims of every kind, as well as any other income assimilated to income from money lent by the taxation law of the State in which income arises.
4. 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 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.
5. Interest shall be deemed to arise in a Contracting State when the payer is that State itself, a political or administrative subdivision, a local authority or 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.
6. 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 Convention.
Article 12
Royalties
1. Royalties 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 royalties may also be taxed in the Contracting State in which they arise and according to the laws of that State but, if the recipient is the beneficial owner of the royalties, the tax so charged shall not exceed 10% of the gross amount of the royalties.
The competent authorities of the Contracting States shall by mutual agreement settle the mode of application of this limitation.
3. The term “royalties” as used in this Article means payments of any kind received as a consideration for the use of, or the right to use, any copyright of literary, artistic or scientific work, including cinematograph films or films or tapes for radio or television broadcasting, any patent, trade mark, design or model, plan, secret formula or process, or for the use of, or the right to use, industrial, commercial, or scientific equipment, or for information concerning industrial, commercial or scientific experience.
The term “royalties” shall also include payments for technical assistance which is supplied in connection with the use of, or the right to use, any right, property or information referred to in this paragraph.
4. The provisions of paragraphs 1 and 2 shall not apply if the beneficial owner of the royalties, being a resident of a Contracting State, carries on business in the other Contracting State, in which the royalties arise, through a permanent establishment situated therein, or performs in that other State independent personal services from a fixed base situated therein, and the right or property in respect of which the royalties 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. Royalties shall be deemed to arise in a Contracting State when the payer is that State itself, a political or administrative subdivision, a local authority or a resident of that State. Where, however, the person paying the royalties, 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 royalties was incurred, and such royalties are borne by such permanent establishment or fixed base, then such royalties shall be deemed to arise in the Contracting State in which the permanent establishment or fixed base is situated.
6. Where by reason of a special relationship between the payer and the beneficial owner of the royalties or between both of them and some other person, the amount of the royalties, having regard to the use, right or information for which they are 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.

(a) Where a resident of Luxembourg derives income or owns capital which, in accordance with the provisions of this Convention, may be taxed in Portugal, Luxembourg shall, subject to the provisions of subparagraphs (b) to (e), exempt such income or capital from tax.
(b) Where a resident of Luxembourg derives items of income which, in accordance with the provisions of Articles 10, 11 and 12, may be taxed in Portugal, Luxembourg shall allow as a deduction from the tax on the income of that resident an amount equal to the tax paid in Portugal.Such deduction shall not, however, exceed that part of the tax, as computed before the deduction is given, which is attributable to the items of income received from Portugal.
(c) Notwithstanding subparagraph (b), dividends paid by a company which is a resident of Portugal and which is subject therein to a tax corresponding to the Luxembourg corporate income tax to a capital company (société de capitaux) which is a resident of Luxembourg and which holds since the beginning of its accounting year directly at least 25% of the capital of the first-mentioned company shall be subject to the treatment provided for in subparagraph (a).
(d) Where by reason of special provisions for the purpose of encouraging the economic and social development of Portugal, the interest and royalties referred to, respectively, in subparagraph (a) of paragraph 2 of Article 11 and paragraph 2 of Article 12 paid by a resident of Portugal are exempt from tax or subject to a reduced rate of tax in Portugal, then the tax paid in Portugal on such income shall, for the purposes of application of subparagraph (b) of this paragraph, be deemed to have been paid in Portugal at a rate of 10% of its gross amount. The provisions of this subparagraph shall apply for a period of 8 years beginning on 1 January of the year following that in which this Convention enters into force.
(e) Where a resident of Luxembourg derives income or owns capital which, in accordance with any provision of this Convention other than subparagraph (c) of this paragraph, is exempt from tax in Luxembourg, Luxembourg may nevertheless, in calculating the amount of tax on the remaining income or capital of such resident, take into account the exempted income or capital.
2. In the case of Portugal, double taxation shall be avoided, in accordance with the provisions applicable under the laws of Portugal (as long as they do not contradict the general principles provided for in this paragraph), as follows:
(a) Where a resident of a Portugal derives income which, in accordance with the provisions of this Convention, may be taxed in Luxembourg, Portugal shall allow, as a deduction from the tax on the income of that resident, an amount equal to the tax paid in Luxembourg.Such deduction shall not, however, exceed that part of the income tax, as computed before the deduction is given, which is attributable to the income which may be taxed in Luxembourg.
(b) Where a company which is a resident of Portugal receives dividends from a company which is a resident of Luxembourg in which the first-mentioned company holds directly a participation in the capital of at least 25%, Portugal shall, for the purposes of determining the taxable profit subject to corporate income tax, allow as a deduction an amount equal to 95% of the dividends included in the taxable base, under the terms and conditions provided for in the laws of Portugal.
(c) Where, in accordance with any provision of this Convention, 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 25
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 the other State in the same circumstances are or may be subjected.

2. The term “nationals” means:
(a) any individual possessing the nationality of a Contracting State;
(b) any legal person, partnership or association deriving its status as such from the laws in force in a Contracting State.
3. 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. This provision 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.
