Branch or Subsidiary in Spain? Choosing the Right Legal Presence for Your Company

Compare subsidiaries (S.L.), branches, representative offices and permanent establishments to understand which structure best fits your expansion into Spain

Lawants Guide · Legal Presence in Spain

Most foreign companies entering Spain begin by comparing a branch and a subsidiary, the two main structures for conducting commercial activity. But the right legal presence also depends on whether the business only needs a non-commercial representative office, or whether its activities may already create a permanent establishment for Spanish tax purposes. The correct choice starts with how the company intends to operate: the activities it will carry out, the autonomy it requires, the liabilities the parent is prepared to assume, and whether the Spanish presence is temporary or part of a long-term expansion. Getting this decision wrong can create unexpected tax exposure, operational restrictions, and costly restructuring later.

Branch vs Subsidiary vs Representative Office in Spain: Key Differences

For foreign companies expanding into Spain, there are three formal ways to establish a legal presence: a subsidiary, a branch, or, in more limited circumstances, a representative office. Each serves a different business purpose and differs in terms of legal liability, tax treatment, operational flexibility, and the activities it can carry out.

Most companies compare only a branch and a subsidiary, as these are the two structures used to conduct business in Spain. However, a representative office may be appropriate for businesses that only need a non-commercial local presence.

The subsidiary refers to a Spanish company, typically incorporated as a Sociedad Limitada (S.L.), that is owned or controlled by a foreign parent company. A branch, by contrast, is not a separate legal entity but a registered extension of the foreign company itself.

Alongside these three legal structures, foreign companies should also understand the concept of permanent establishment. Unlike the others, it is not a legal form that can be chosen, but a tax status that may arise if business activities in Spain exceed certain thresholds.

For this reason, choosing the right legal structure should always start with your business objectives, not with the incorporation process itself. The most suitable option depends on how you plan to operate in Spain, the level of autonomy you need, your exposure to legal and tax risks, and your long-term expansion plans.

This guide compares each structure and helps you identify which one best fits your project. The table captures the structural differences at a glance. The sections below explain each structure in detail and when it actually fits a real expansion scenario.

Structure Assessment

Before choosing a branch or subsidiary, confirm what your business will actually need to do in Spain.

Lawants works exclusively with foreign companies entering the Spanish market. Before any incorporation begins, we review your planned activities, parent company jurisdiction, tax treaty position, liability exposure and long-term objectives to determine whether a subsidiary, branch or another form of presence is the most appropriate solution.

How to Choose the Right Business Structure in Spain

Most foreign companies arrive at the structure decision having already formed a view based on what they have read online. In our experience, the view is usually correct for the most obvious cases and wrong for the nuanced ones.

These questions help filter the most common situations cleanly:

1. Does your Spanish presence need to generate revenue? If yes, the representative office is excluded immediately. It is strictly limited to auxiliary and preparatory activities: market research, promotion, liaison. The moment it invoices, signs a revenue contract, or takes on a commercial role, the risk of permanent-establishment treatment becomes substantial and requires immediate tax assessment.
2. Do you need liability protection for the parent company? If yes, the S.L. subsidiary is the only structure that provides it. Both the branch office and the permanent establishment leave the foreign parent directly exposed to Spanish liabilities, with no corporate ring-fence. For companies entering a market where commercial, employment, or product liability risk is material, this is usually the deciding factor.
3. Will you hire employees in Spain? If you plan to build a team in Spain, an S.L. is almost always the more appropriate vehicle. Employees hired under Spanish labour law create significant obligations and potential liability; these sit more cleanly within a separate Spanish legal entity than within a branch, where every employment decision may require formalisation at parent company level. A representative office can only employ staff in auxiliary roles with no revenue-generating function.
4. Is your Spanish presence permanent or project-based? A branch office makes sense when the parent company wants to operate directly under its own name in Spain, or when the Spanish activity is tied to a specific project or contract with a defined end date. An S.L. subsidiary signals a long-term commitment and is treated as such by Spanish banks, clients, suppliers, and public administrations.

For the vast majority of foreign companies entering Spain with a genuine commercial operation, the Sociedad Limitada (S.L.) is the right starting point. It provides full limited liability, is treated as a Spanish company for all legal and commercial purposes, and can operate across all business activities without restriction.

The branch office is the right choice when the parent company specifically wants to operate directly without creating a separate entity and is comfortable with the liability exposure that entails. The representative office is a market-testing tool, not a commercial structure.

Subsidiary vs Branch vs Representative Office in Spain: How Each Structure Works in Practice

The differences between a subsidiary, a branch, and a representative office become clearer when each structure is considered in practical terms: what the company can do in Spain, who assumes liability, how the operation is taxed, and how much autonomy it has from the foreign parent.

The following sections examine how each form works, when it is typically appropriate, and the limitations that may make another structure more suitable. Permanent establishment is considered separately because it is not a structure to establish, but a status that may arise from the company’s actual activities in Spain.

Other legal forms are available under Spanish commercial law, including partnerships and cooperative entities, but they are rarely used by foreign companies establishing a conventional business presence.

They are covered separately in our extended guide to business structures in Spain.

Subsidiary Company (S.L.)

A Spanish subsidiary is an independent company incorporated under Spanish law, most commonly as a Sociedad Limitada (S.L.). It is owned by the foreign parent but is a legally distinct entity with its own personality, assets, and obligations.

The parent’s liability is limited to the capital contributed: if the Spanish S.L. incurs debts or legal claims, the parent’s global assets are not exposed. In our experience, this ring-fencing of risk is the primary reason most foreign companies choose the subsidiary over the branch once they understand the practical difference.

When it works best

• Long-term commercial operations with revenue, employees, and contracts in Spain
• Liability protection: the parent’s global assets are protected from Spanish debts and claims
• Local credibility: treated as a fully committed Spanish entity by banks, clients, and public administrations
• Treaty and directive access: as a Spanish tax resident, the S.L. can access Spain’s full DTT network and qualify for applicable withholding exemptions on dividend distributions
• Exit flexibility: transferring S.L. shares to new investors or acquirers is substantially simpler than disposing of a branch

When it may not be the right choice

• When the Spanish presence is genuinely short-term and the parent is comfortable with the liability exposure of a branch
• When early-year losses need to flow through to the parent for tax consolidation in the home jurisdiction
• When the company specifically wants to operate under its own parent brand without creating a separate entity

Branch Office (Sucursal)

A branch office (sucursal) is a formal extension of the foreign parent, not a new company. It can invoice, sign contracts, and hire staff, but it does so as the parent company. The parent bears full and direct liability for everything the branch does in Spain; there is no corporate ring-fence. The branch is also limited to the activities included in the parent’s corporate purpose, and every significant decision requiring parent board approval must be formalised through an apostilled, translated notarial deed before Spanish authorities will recognise it.

When it works best

• Direct parent brand presence: the company wants to operate under its own name without creating a new entity
• Short-term or project-based activity: a defined contract or infrastructure project with a clear end date
• Early-year loss consolidation: branch losses may flow through to the parent in some home jurisdictions, a benefit the S.L. cannot provide
• Favourable treaty position: the parent’s home country has a treaty that reduces or eliminates the supplementary tax on profit repatriation

When it may not be the right choice

• When parent liability exposure from Spanish operations is a concern: there is no ring-fence
• For non-EU companies without a favourable treaty, the 19% supplementary tax on profit repatriation can make the branch structurally more costly than a subsidiary over time
• When building a long-term team and local credibility: Spanish banks and counterparties treat a local S.L. with more confidence than a foreign branch
• When intragroup payments (royalties, management fees) need to be deductible at the Spanish level: generally not possible for a branch
• When the parent company needs to limit disclosure of its own financial information: with a branch, the foreign parent must include part of its own accounting data in Spanish tax filings, which is not required for a subsidiary that files entirely independently

Representative Office

A representative office is not a commercial structure. It permits market research, brand promotion, and liaison with clients and suppliers: nothing that generates revenue or concludes contracts. It is suitable only while the Spanish activity remains genuinely preparatory or auxiliary. Once local staff begin to negotiate commercial terms, invoice, or perform the company’s core business functions, the risk of permanent-establishment treatment arises and requires immediate tax assessment.

• Use it when: the company is genuinely exploring the market, establishing contacts, or attending trade fairs before committing to a commercial structure, with no revenue-generating activity planned
• Do not use it when: employees will have client-facing or revenue-related responsibilities, when commercial agreements need to be signed, or when the presence will extend beyond 12 to 18 months without evolving into a formal commercial structure

Permanent Establishment

The permanent establishment (PE) in Spain is the most misunderstood concept in this comparison, because it is the only category that may arise without a deliberate decision to create it.

A company does not incorporate a PE; it discovers it has one, usually during a tax audit. Most companies that contact us about PE risk do so because they have already been operating in Spain informally for one or two years (through a local agent, a remote employee, or a sales team based in Spain) and they have realised the exposure only after the fact.

Under Article 5 of the OECD Model Convention and Article 13 of Spain’s Non-Resident Income Tax Law (LIRNR), a permanent establishment exists whenever a foreign company has a fixed place of business in Spain through which it carries out business activities.This includes an office, a workshop, a construction project lasting more than 12 months, or a dependent agent in Spain who has authority to conclude contracts on behalf of the foreign company. The test is factual, not formal: it does not matter whether the company has formally established a branch or representative office. What matters is what is actually happening on the ground.

The practical difference between a branch and a PE is one of form: a branch is a PE that has been formally registered, with a notarial deed, Mercantile Registry filing, and a registered director. A PE can exist without any of that. Both leave the parent fully exposed to Spanish liabilities and both are limited to the parent’s corporate purpose.

Spanish Subsidiary vs Branch vs Representative Office: Tax Comparison

The standard corporate tax rate is generally 25% for both the S.L. and the branch.

That is where the similarity ends. The real differences lie in how profits are sent back to the parent, whether intragroup payments are deductible, which double taxation treaties apply, and how the structure is treated in the parent company’s home jurisdiction. The representative office pays no Spanish tax as long as it stays within its permitted scope.

The table below compares the three structures across the factors that actually drive the tax cost over time.

Key thresholds and rates for 2026: The micro-company regime (19% on the first €50,000 of taxable income, 21% above) and the SME regime (23% on taxable income below €10 million) apply where the company meets specific conditions.

The participation exemption on dividend distributions requires the parent to hold at least 5% of the subsidiary for a minimum of one year before the distribution.

Withholding tax under tax treaties applies at 19% for EU and EEA resident parents and 24% for non-EU and non-EEA parents. Spain has signed 103 double taxation treaties, of which 95 are currently in force.

Subsidiary vs Branch vs Representative Office in Spain: Set-up Requirements

All three structures share certain prerequisites: a Spanish NIF for the entity, a NIE for each individual director, sworn Spanish translations and apostille for all foreign documents, a Digital Certificate for electronic filings, and Form D1-A (declaration of foreign investment) for S.L. and branch.

The key differences lie in what each structure additionally requires.

Procedure and Timeline for Opening a Spanish Subsidiary or Branch Office

The setup processes for an S.L. and a branch are broadly similar in length (typically 4 to 8 weeks from start to finish) but different in what drives the timeline.

For both structures, the bottleneck is almost never the Registro Mercantil itself, which processes registrations within 7 to 15 working days once the deed is submitted. The bottleneck is the documentation that has to be in place before the notary appointment can happen.

• An S.L. requires five steps that partially overlap: NIF/NIE applications, name reservation, bank account and capital deposit, notarial deed, and Registro Mercantil filing. The registry processes registrations within 7 to 15 working days. Total elapsed time depends primarily on the NIF for any foreign corporate shareholder, which takes two to four weeks and must start on day one, not after the name is reserved.
• A branch follows a similar sequence but requires the parent’s corporate documents, all apostilled and sworn-translated, before the notary appointment. Every subsequent significant decision at parent level must be formalised the same way. This ongoing overhead is one of the main operational costs of the branch that does not appear in the initial setup comparison.
• A representative office requires only AEAT registration for a NIF (prefix N), a Spanish address, and a contact person. No notary, no registry, no capital. It can be operational in days.

Structure Assessment

The right legal structure depends on your business model, not on which option is easiest to incorporate.

Before recommending a subsidiary, branch or representative office, we analyse how your company will operate in Spain, your parent company’s jurisdiction, the applicable tax treaties and your long-term objectives. This allows us to identify the structure that best supports your expansion from the outset.

Every structure recommendation is reviewed personally by our Managing Director.

Which Spanish Structure Fits Your Situation?

In our experience, the structure decision becomes clear very quickly once the actual business model is on the table. Most foreign companies entering Spain fall into one of the scenarios below. The cases where the answer is genuinely ambiguous are those where the parent’s home jurisdiction tax position or the applicable treaty changes the calculation — and those require a specific analysis, not a general guide.

Lawants reviews all three dimensions before recommending a structure: the Spanish legal and tax position, the parent company’s home jurisdiction, and the applicable treaty.

Common Mistakes When Choosing Between Subsidiary, Branch and other Structures in Spain

In over twenty years working exclusively with foreign companies entering Spain, we have seen the same structural errors repeated across very different industries and profiles. Each of them was avoidable with the right analysis before the structure was chosen.

• Choosing a branch simply to avoid incorporation. The minimum legal capital for a Spanish S.L. is €1, though specific rules apply until share capital and legal reserve together reach €3,000. The capital becomes a company asset, not a fee. Avoiding the S.L. in favour of a branch introduces unlimited parent liability and, for non-EU companies, a 19% supplementary tax on profit repatriation. The apparent administrative saving becomes a structural cost that compounds over time.
• Treating a permanent establishment as a structure you can choose. A PE is not something a company selects. It is a tax status that arises when a foreign company operates in Spain through a fixed place of business or a dependent agent, regardless of what formal structure has or has not been established. Companies that believe they are operating as a representative office but carry out commercial activity have already created a PE, with retroactive tax obligations from day one and potential penalties for non-declaration.
• Opening a representative office and then carrying out commercial activity. This is the most common representative office mistake. Once the office begins invoicing, negotiating commercial terms, or employing staff in revenue-generating roles, the AEAT may reclassify it as a permanent establishment. Tax obligations apply retroactively with interest and potential penalties. The transition to a commercial structure must be formalised before commercial activity begins, not after it has already started.
• Incorporating an S.L. when a branch would have been sufficient. Not every situation requires a subsidiary. A company executing a specific, short-term contract in Spain, or wanting to operate directly under the parent brand without building a long-term local presence, may genuinely be better served by a branch. The S.L. involves ongoing compliance obligations, annual accounts, and governance requirements that a branch avoids. Over-structuring creates administrative cost without operational benefit.
• Ignoring the tax consequences in the parent company’s jurisdiction. The structure decision in Spain does not exist in isolation. A branch that allows early-year losses to flow through to the parent may be attractive from a Spanish perspective but create complications in the home jurisdiction. An S.L. that distributes dividends exempt in Spain may still be taxable when they reach the parent under its local rules. The Spanish analysis and the home-country analysis must be done together, not sequentially.

What Happens If You Choose the Wrong Structure to Operate in Spain?

The wrong structure does not usually announce itself immediately. It reveals itself gradually: when the first significant contract needs to be amended and the branch requires a new apostilled board resolution to do it, when the company wants to hire its third employee in Spain and realises the employment obligations sit directly with the parent; when the first dividend distribution triggers a tax cost that was not in any projection, when the company wants to bring in a local investor and the branch has no shares to transfer.

By the time the problem is visible, the correction is expensive. What follows is what a structural change in Spain actually involves.

Can You Change Structure Later?

Yes, but the cost of changing structure depends significantly on how far the original structure has developed. A company that has operated as a branch for three years with assets, employees, and contracts in Spain faces a real legal and tax restructuring process to convert to a subsidiary. It is not a simple administrative change.

The most common conversion route is the contribution of a branch of activity (aportación de rama de actividad), where the branch’s assets and liabilities are transferred to a newly incorporated S.L. This is a taxable event under certain conditions, requires careful valuation of the transferred assets, and involves notarial, registry, and tax filing obligations that make it a meaningful project rather than a routine restructuring. For a representative office, the transition to a commercial structure simply requires closing the representative office and establishing the chosen commercial structure before any revenue activity begins.

The practical implication is simple: the structure decision is most efficiently made before operations begin, not after they have created a structure that then needs to be unwound. The cost of changing structure after two or three years almost always exceeds the cost of analysing the right structure from the start.

Why a Spanish S.L. Is Often the Starting Point for Long-Term Operations

It is worth being explicit about why the Sociedad Limitada is the standard choice for foreign companies in Spain, because the answer is not simply that it is the most popular option or the default recommendation.

The S.L. is the most common structure because most foreign companies entering Spain share a set of characteristics that happen to align with what the S.L. provides: they plan a genuine commercial operation with revenue, they intend to hire staff, they want their parent company protected from Spanish liabilities, and they expect to be in Spain for the medium to long term. When those characteristics are present, the S.L. is not the most popular choice among several comparable options. It is the structurally correct choice, and the alternatives involve trade-offs that most companies are not willing to make when they understand them clearly.

The branch and the representative office are not inferior versions of the S.L. They are different tools designed for different situations.

The issue is not that these structures are wrong in principle: it is that they are frequently chosen for reasons that have nothing to do with their actual design, and everything to do with their perceived simplicity or cost.

Why Foreign Companies Structure Their Spanish Presence with Lawants

Most foreign companies that contact us about structure have already done their research. They have read the same comparisons, they know the broad differences between branch and subsidiary, and they have a provisional view. What they are looking for is a confirmation that their situation fits the general case, or an explanation of why it does not.

Lawants works exclusively with foreign companies and entrepreneurs entering the Spanish market, with lawyers and tax advisors operating under one roof. The structure decision is simultaneously a legal decision, a tax planning decision, and a commercial positioning decision. For international companies, it also involves analysing how the Spanish structure interacts with the parent company’s home jurisdiction tax position, the applicable double taxation treaty, and any group-level considerations. These elements are not separable, and they are not effectively analysed by a firm that handles only one of them.

The structure is the foundation. Every compliance obligation, every tax filing, every commercial contract, and every future restructuring or exit will rest on the choice made at this stage. It deserves more than a checklist.
