Original & source
§
- 1. For the purposes of this Convention, the term “permanent establishment” means a fixed place of business through which the business of an enterprise is wholly or partly carried on.
§
- 2. The term “permanent establishment” includes especially:
§
- a) a place of management;
§
- b) a branch;
§
- c) an office;
§
- d) a factory;
§
- e) a workshop; and
§
- f) a mine, an oil or gas well, a quarry or any other place of extraction of natural resources.
§
- 3. A building site or construction or installation project constitutes a permanent establishment only if it lasts more than 12 months.
§
- 4. Notwithstanding the preceding provisions of this Article, the term “permanent establishment” shall be deemed not to include:
§
- a) the use of facilities solely for the purpose of storage, display or delivery of goods or merchandise belonging to the enterprise;
§
- b) the maintenance of a stock of goods or merchandise belonging to the enterprise solely for the purpose of storage, display or delivery;
§
- c) the maintenance of a stock of goods or merchandise belonging to the enterprise solely for the purpose of processing by another enterprise;
§
- d) the maintenance of a fixed place of business solely for the purpose of purchasing goods or merchandise or of collecting information, for the enterprise;
§
- e) the maintenance of a fixed place of business solely for the purpose of carrying on, for the enterprise, any other activity of a preparatory or auxiliary character;
§
- f) the maintenance of a fixed place of business solely for any combination of activities mentioned in sub-paragraphs a) to e), provided that the overall activity of the fixed place of business resulting from this combination is of a preparatory or auxiliary character.
§
- 5. Paragraph 4 shall not apply to a fixed place of business that is used or maintained by an enterprise if the same enterprise or a closely related enterprise carries on business activities at the same place or at another place in the same Contracting State and
§
- a) that place or other place constitutes a permanent establishment for the enterprise or the closely related enterprise under the provisions of this Article, or
§
- b) the overall activity resulting from the combination of the activities carried on by the two enterprises at the same place, or by the same enterprise or closely related enterprises at the two places, is not of a preparatory or auxiliary character,
§
- provided that the business activities carried on by the two enterprises at the same place, or by the same enterprise or closely related enterprises at the two places, constitute complementary functions that are part of a cohesive business operation.
§
- 6. For the purposes of paragraph 5, an enterprise is closely related to an enterprise if, based on all the relevant facts and circumstances, one has control of the other or both are under the control of the same persons or enterprises. In any case, an enterprise shall be considered to be closely related to an enterprise if one possesses directly or indirectly more than 50 per cent of the beneficial interest in the other (or, in the case of a company, more than 50 per cent of the aggregate vote and value of the company’s shares or of the beneficial equity interest in the company) or if a person or another enterprise possesses directly or indirectly more than 50 per cent of the beneficial interest (or, in the case of a company, more than 50 per cent of the aggregate vote and value of the company’s shares or of the beneficial equity interest in the company) in the two enterprises.
§
- 7. Notwithstanding the provisions of paragraphs 1 and 2, where a person – other than an agent of an independent status to whom paragraph 8 applies – is acting on behalf of an enterprise and has, and habitually exercises, in a Contracting State an authority to conclude contracts on behalf of the enterprise, that enterprise shall be deemed to have a permanent establishment in that State in respect of any activities which that person undertakes for the enterprise, unless the activities of such person are limited to those mentioned in paragraph 4 which, if exercised through a fixed place of business, would not make this fixed place of business a permanent establishment under the provisions of that paragraph.
§
- 8. An enterprise shall not be deemed to have a permanent establishment in a Contracting State merely because it carries on business in that State through a broker, general commission agent or any other agent of an independent status, provided that such persons are acting in the ordinary course of their business.
§
- 9. 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.

Edition-specific publisher status

HMRC reports signature in London on 15 September 2025 and entry into force on 29 December 2025. It reports effects from 1 January 2026 for UK withholding and Portuguese withholding/other taxes, 1 April 2026 for UK Corporation Tax, and 6 April 2026 for UK Income Tax and Capital Gains Tax. These are distinct date roles. The HMRC update dated 8 January 2026 confirms in-force status; the URL still ends “not-in-force” and must not override actual title/index.
