Short answer
EU law looks at how the provider actually participates in the host Member State's economy. A provider is exercising freedom of establishment under Article 49 of the Treaty on the Functioning of the European Union (TFEU) when it operates there on a stable and continuous basis, usually from a base through which it presents itself to the host market. Article 56 TFEU instead protects a provider established in one Member State that supplies services across a border without becoming established in the host state.
“Temporary” is not a fixed number of days. Duration, regularity, periodicity and continuity all matter. Repeated work, a long project or even a local office can remain cross-border service provision if the infrastructure merely enables the particular service. Conversely, calling an operation “temporary” will not prevent it being treated as establishment when the economic reality is a durable local business.
The classification selects the relevant Treaty chapter and, where applicable, a different part of EU secondary legislation. Under Directive 2006/123/EC on services in the internal market, establishment authorisation falls principally under Chapter III, while temporary cross-border provision falls under Chapter IV. Those regimes permit different host-state requirements and justifications. The directive's scope, exclusions and any sector-specific EU rules must therefore be checked before drawing a practical conclusion.
Start with the economic reality, not the business label
Article 49 TFEU prohibits restrictions on nationals of one Member State establishing themselves in another. It covers self-employed activity and companies, including agencies, branches and subsidiaries. It also permits more than one establishment: retaining a principal office at home does not prevent a second establishment in another Member State.
Article 56 TFEU addresses a different pattern. It protects services supplied within the EU by a person established in a Member State other than that of the recipient. Article 57 makes the relationship between the two freedoms explicit:
“Without prejudice to the provisions of the Chapter relating to the right of establishment, the person providing a service may, in order to do so, temporarily pursue his activity in the Member State where the service is provided, under the same conditions as are imposed by that State on its own nationals.”
—
Services are therefore the temporary, cross-border category where the establishment rules do not apply. The classification is objective. Incorporation documents, a contract's description and the provider's preferred label may be evidence, but none replaces an assessment of the activity actually conducted in the host state.
The provider, recipient or service may cross the border. The question remains whether the provider has joined the host state's economic life on a stable basis for the activity at issue.
What counts as stable and continuous participation?
The Court of Justice set out the core distinction in Gebhard, Case C-55/94. The case concerned a lawyer who had lived and practised for years in Italy and opened his own chambers there. The Court described establishment broadly:
“allowing a Community national to participate, on a stable and continuous basis, in the economic life of a Member State other than his State of origin”
—
That formulation directs attention to real economic integration. Relevant indicators include a fixed professional or commercial base, an indefinite or open-ended local presence, management and staff located there, and the way the provider holds itself out to clients in the host market. No indicator is automatically decisive.
The Court confirmed that approach in VšĮ Vilniaus tarptautinė mokykla, Case C-48/24, on 12 February 2026. A private school providing remunerated education from Lithuania fell within Article 49 where foreign shareholders could exert definite influence. Establishment still required genuine economic activity through a fixed host-state base for an indefinite period. Activity and economic presence—not ownership or registration alone—complete the classification.
The same judgment explains the other side of the line:
“the temporary nature of the activities in question has to be determined in the light, not only of the duration of the provision of the service, but also of its regularity, periodicity or continuity.”
—
This is a multi-factor test. A substantial construction project may last several years yet remain a cross-border service. The question is whether the provider has a durable host-state centre of activity or still supplies from an establishment elsewhere.
An office and repeated work are evidence, not shortcuts
A provider may need an office, consulting room, equipment or project site to perform a temporary service. Gebhard confirms that necessary infrastructure does not by itself convert services into establishment. The harder factual question is what that infrastructure does: is it limited to delivering the particular cross-border work, or does it enable a stable local business that presents itself to the host market?
The Court reinforced that point in Schnitzer, Case C-215/01, concerning building work repeatedly supplied in another Member State. It rejected a mechanical time limit:
“No provision of the Treaty affords a means of determining, in an abstract manner, the duration or frequency beyond which the supply of a service or of a certain type of service in another Member State can no longer be regarded as the provision of services within the meaning of the Treaty.”
—
The Court added that repeated similar services are not enough if the provider lacks infrastructure enabling stable and continuous local activity and does not hold itself out from it to the host market. This avoids treating every repeated engagement as establishment while preventing a de facto local business from relying on time-limited contracts.
Why classification changes the regulatory analysis
At Treaty level, classification decides whether Article 49 or Article 56 is the starting point. Both prohibit discriminatory rules and unjustified obstacles, subject to applicable exceptions and proportionality. Classification identifies the correct test and harmonising legislation; it does not determine the result by itself.
Directive 2006/123/EC shows the practical difference. For activities within its scope, Article 4(5) defines establishment as actual economic activity for an indefinite period through stable infrastructure from which services are actually carried out. Chapter III then governs establishment. Under Article 9, a host Member State may use an authorisation scheme only where it is non-discriminatory, justified by an overriding reason relating to the public interest, and not replaceable by a less restrictive effective measure.
Chapter IV governs a provider established in another Member State. Article 16 states:
“Member States shall respect the right of providers to provide services in a Member State other than that in which they are established.”
—
Within that provision, a host requirement must be non-discriminatory, proportionate and necessary on specified grounds: public policy, public security, public health or environmental protection. Article 16(2) also prohibits listed requirements, including an obligation to establish locally and, subject to exceptions in EU law, host-state authorisation or professional registration.
Classification can therefore change whether a licence, registration, legal-form rule, office requirement or market-access condition is assessed under Chapter III or Chapter IV, and which justification is available.
The comparison has limits. The Services Directive excludes several fields, including financial, transport and healthcare services, temporary-work agencies and gambling. Article 17 contains additional derogations, and professional qualifications, posted workers and other regulated sectors may be governed by specific EU acts. National transposition determines the domestic procedures. A careful analysis therefore classifies the activity and then checks the applicable legislative regime; it does not stop at the Treaty label.
A practical classification checklist
Ask these questions about the particular service and host state:
- Where is the provider established for this activity? Identify where the service is organised and carried out, not merely the registered office.
- Is the host presence open-ended and economically integrated? Look for a stable base, local management or staff, and sustained presentation to host-state clients.
- What do duration, regularity, periodicity and continuity show together? No factor is an automatic threshold.
- What is local infrastructure for? Project-specific facilities may support temporary services; a base supporting an indefinite local business points towards establishment.
- Is the situation genuinely cross-border? Article 56 requires the relevant connection between different Member States.
- Which EU measure governs the sector? Check the Services Directive's scope and derogations, professional-qualification rules and any sector-specific legislation.
- What precisely does the host rule require? A licence, registration, local office, legal form or qualification condition may be treated differently under the two regimes.
- Can the restriction be justified and is it proportionate? Classification selects the framework, but necessity and less restrictive alternatives remain central.
Conclusion
EU law distinguishes establishment from cross-border services by examining the provider's real participation in the host economy. Stable and continuous activity from an established local base falls under establishment; genuinely temporary cross-border activity falls under services. Duration, repetition and infrastructure inform that assessment but do not decide it alone.
The distinction matters because it selects the Treaty freedom and, where relevant, the establishment or temporary-services regime in EU secondary law. That can change which host-state authorisations, registrations and market-access conditions are permissible and which justifications are available. The reliable method is therefore factual classification first, followed by a scope, harmonisation and proportionality analysis.
