Permanent establishment in Spain: definition and requirements
A permanent establishment in Spain (PE) refers to a stable business presence in Spanish territory through which a non-resident company carries out all or part of its economic activity and may therefore become subject to taxation in Spain.
The concept of permanent establishment is a key element of international tax law, as it determines when a foreign company must pay taxes in Spain on profits derived from its business presence in the country.
In Spain, this concept is primarily regulated by the Non-Resident Income Tax Act (IRNR) and interpreted in accordance with the Double Taxation Treaties (DTTs) signed by Spain. These treaties are largely based on Article 5 of the OECD Model Tax Convention.
Traditionally, a permanent establishment was linked to a structured physical presence. However, the expansion of remote work and digital business models has prompted a reassessment of the traditional taxation criteria, particularly in light of the updated OECD Model Convention Commentaries.
What is a permanent establishment in Spain?
In general terms, a permanent establishment in Spain exists when a company has a fixed place of business in Spanish territory through which it conducts out all or part of its activities.
Requirements for a permanent establishment in Spain
The existence of a permanent establishment generally requires three key elements.
Existence of a place of business
There must be a physical location or facility, such as an office, branch, factory, workshop, or construction project lasting a sufficient period of time.
Fixed nature
The place of business must demonstrate a certain degree of geographic and temporal stability. Although permanence is not required indefinitely, the presence must show continuity rather than occasional activity.
Non-auxiliary business activity
The activity carried out must not be merely preparatory or auxiliary. It must form a core part of the company’s business operations.
In addition to the so-called material permanent establishment, international tax law also recognises a dependent agent permanent establishment. This situation arises when a person located in Spain acts on behalf of a foreign company and:
- Concludes contracts in its name
- Plays the principal role in negotiating those contracts
- Acts habitually under the legal and economic control of the company.
Following the OECD BEPS Project, traditional exclusions such as storage, display of goods or auxiliary activities must now be analysed more strictly and from a substantive perspective.
Until recently, the classical interpretation considered that the presence of an employee working from home did not automatically create a permanent establishment, since the home was generally not considered a place “at the disposal of the company.”
Earlier OECD Commentaries already indicated that occasional or voluntary remote work should not in itself modify the allocation of taxing rights between states, anticipating the debate now intensified by the structural expansion of remote work.
Conclusion
A permanent establishment in Spain is a key factor in determining when a foreign company becomes liable to Spanish taxation. Its existence depends mainly on the presence of a fixed place of business or the activities of a dependent agent acting on behalf of the company.
In an increasingly globalised business environment, understanding this concept correctly is essential to prevent tax risks and structure business activities in Spain appropriately.
