Permanent Establishment in Spain (Establecimiento Permanente)

What Is a Permanent Establishment?

The concept of permanent establishment (establecimiento permanente, EP) is the pivotal test in international tax law that determines when a foreign company’s activities in a country become taxable in that country. Without a permanent establishment, a non-resident company pays tax only in its home country on its global income. With a permanent establishment in Spain, the company becomes subject to Spanish Corporate Tax on the profits attributable to that Spanish presence.

Spain’s domestic definition is contained in Article 13 of the Non-Resident Income Tax Law (Ley del IRNR, Real Decreto Legislativo 5/2004). Where a double-tax treaty applies, the treaty definition takes precedence over domestic law, and most of Spain’s 100+ treaties use the OECD Model definition.

How It Works in Spain

Fixed Place of Business Test

The primary test is whether the foreign company has a fixed place of business in Spain through which it wholly or partly carries on its business. Key elements:

1. Fixed: A certain degree of permanence — temporary or transitory presences generally do not qualify, though even short-duration activities can constitute a PE if they recur
2. Place of business: Physical premises (owned, rented, or otherwise used) or any location where business is habitually conducted
3. Through which business is carried on: The foreign company must carry out actual business activity through the location, not merely preparatory or auxiliary activities

Classic fixed-place PEs in Spain:

• Branch offices
• Management offices
• Factories or manufacturing plants
• Mines, oil wells, quarries, and similar extractive sites
• Service delivery centres that handle customers directly

Construction and Project Site PE

A special rule applies to construction or installation projects: a construction site, building, or installation project constitutes a PE if it lasts more than 12 months (under the OECD standard). Spain’s domestic law sets the threshold at 6 months, but treaty provisions (where more favourable) prevail. Projects designed to circumvent this threshold by artificial splitting across contracts or entities are challenged by the AEAT.

Dependent Agent PE

Even without a fixed place of business, a foreign company may have a PE through a dependent agent — an individual or entity in Spain who habitually concludes contracts (or habitually plays a principal role in their conclusion) in the name of the foreign company, without being an independent agent acting in the ordinary course of business.

This is the test most frequently triggered for foreign companies that have Spanish employees, commercial agents, or distributors with authority to bind the foreign company. Key risk factors:

• Spanish employee who negotiates and closes deals for the foreign parent
• Agent whose activities are exclusively (or almost exclusively) for one foreign principal
• Spanish entity that habitually exercises authority to conclude contracts without routinely requiring approval from abroad

Preparatory and Auxiliary Exclusions

Activities that are purely preparatory or auxiliary to the main business do not create a PE. The OECD Model (and Spanish treaties) list specific exclusions:

• Using facilities solely for storage, display, or delivery of goods
• Maintaining a stock of goods for processing by another enterprise
• Purchasing goods or collecting information
• Any combination of the above, provided the overall activity remains preparatory or auxiliary

However, following BEPS Action 7, the anti-fragmentation rule prevents companies from artificially splitting activities between multiple locations to keep each below the PE threshold.

Attribution of Profits to the PE

Once a PE exists, Spain taxes the profits attributable to it — not the foreign company’s worldwide profits. Attribution follows the OECD Authorised Approach (AOA):

1. Identify the functions performed, assets used, and risks assumed by the PE
2. Treat the PE as a hypothetically separate entity transacting at arm’s length with the rest of the foreign enterprise
3. Apply transfer-pricing principles to determine the PE’s notional revenue and costs

This is technically complex and often requires transfer-pricing documentation similar to that required for related-party transactions between separate legal entities.

Key Regulations

• Real Decreto Legislativo 5/2004 (Ley del IRNR), Article 13: domestic PE definition
• Spain’s double-tax treaty network: treaty PE definitions take precedence over domestic law
• Ley 27/2014 (LIS), Articles 16–18: transfer-pricing rules applicable to PE profit attribution
• OECD Model Tax Convention, Article 5 and Commentary (as updated post-BEPS Action 7)
• OECD Report on the Attribution of Profits to Permanent Establishments (2010): the AOA framework

Practical Implications for Foreign Investors

The Sales Team Risk

The most common unintended PE trigger for foreign companies entering the Spanish market is the dependent agent risk arising from Spanish sales staff. If a foreign company hires Spanish-resident employees to develop the market — and those employees negotiate deals, agree on prices, or have authority to bind the foreign company — there is a real risk that the AEAT will treat them as creating a dependent agent PE.

The solution is careful structuring: commissionnaire arrangements (where the agent sells in its own name), genuine independent agency relationships (with multiple principals), or — if the volume justifies it — incorporation of a Spanish subsidiary that acts as the sales entity in its own right.

Digital Business Models

The BEPS project (particularly Actions 1 and 7) has increasingly focused on whether digital businesses with significant user bases in Spain but no physical presence constitute PEs. Spain has lobbied within the OECD for broader PE definitions for digital businesses and has introduced a Digital Services Tax (DST) as a transitional measure. Foreign digital companies with significant Spanish revenues should monitor developments in this area closely.

VAT Registration vs PE

A VAT registration in Spain — which is required for many foreign businesses supplying Spanish customers — does not automatically create a permanent establishment for Corporate Tax purposes. These are two separate concepts governed by different legal frameworks. However, the activities underlying the VAT registration (physical deliveries from Spain, services provided through Spanish premises) may independently trigger PE analysis.

How BMC Can Help

We advise foreign companies at the point of market entry on whether their planned Spanish activities create a PE risk, structure commercial arrangements to manage that risk, and ensure that where a PE does exist it is properly registered and compliant. For companies that discover they have had an undeclared PE in Spain, we manage the voluntary disclosure process with the AEAT to regularise the situation with minimum penalties.
