Is setting up a branch office in Spain as a UK company possible?
- A branch (sucursal) is a permanent establishment of a UK company in Spain and is not a separate legal entity from its UK parent.
- It must be registered in the Spanish Mercantile Registry and obtain a Spanish NIF before commencing operations.
- Branch profits are subject to Spanish Corporate Income Tax (Impuesto sobre Sociedades) at 25%, with limited deductibility for head-office costs.
- Post-Brexit, the UK parent is treated as a non-EU entity, which affects the tax treatment of head-office charges and the availability of certain exemptions.
- A branch does not provide the same liability protection as a Spanish subsidiary (SL), as the UK parent remains fully liable for the branch’s obligations.
- For many UK companies, a Spanish SL is preferable to a branch due to greater flexibility, liability protection, and cleaner tax consolidation.

Why UK companies consider setting up a branch office in Spain
For a UK company expanding into the Spanish market, setting up a branch office in Spain as a UK company is one of two principal routes to establishing a formal legal presence, the other being the incorporation of a Spanish subsidiary.
The branch route has the advantage of simplicity in certain respects: it does not require share capital, it uses the UK parent’s existing governance structure, and it can be established relatively quickly.
However, it also carries significant disadvantages, particularly in the areas of liability, taxation, and administrative burden, which make it the less preferred option for many UK businesses.
This guide sets out the legal framework, the registration process, the tax treatment, and the key decision factors for UK companies considering setting up a branch office in Spain as a UK company.
For a broader view of all the legal vehicle options available to UK businesses entering Spain, our guide to commercial law services in Spain sets out the full range of structures we advise on.
What is a branch office (sucursal) in Spain?
A branch office (sucursal) is a secondary establishment of a foreign company that carries on the company’s activities in Spain on a stable and permanent basis.
It is defined under Article 295 of the Capital Companies Act (Ley de Sociedades de Capital, Royal Legislative Decree 1/2010) and must be registered in the Mercantile Registry of the province in which it is located.
The branch is not a separate legal entity.
It is an extension of the UK parent company, which means the parent is directly and fully liable for all obligations incurred by the branch in Spain.
This is the principal legal distinction from a Spanish SL (Sociedad Limitada), where liability is generally limited to the share capital of the Spanish entity.
Branch versus subsidiary: the key comparison for UK companies
The choice between setting up a branch office in Spain as a UK company and incorporating a Spanish SL subsidiary is one of the most consequential decisions a UK business faces when entering the Spanish market.
| Feature | Branch (sucursal) | Spanish SL (subsidiary) |
|---|---|---|
| Legal personality | None (extension of UK parent) | Separate legal entity |
| Parent liability | Unlimited | Limited to share capital |
| Minimum capital | None | €1 (post-Startup Law 28/2022) |
| Corporate Income Tax | 25% on attributable profits | 25% (15% for qualifying startups) |
| Withholding on profit remittance | Potential supplementary tax applies | 10–15% on dividends (Spain–UK treaty) |
| Annual accounts filing | Must file UK parent accounts in Spain (translated) | Files own Spanish accounts |
| Registration timeline | 4–8 weeks | 2–5 weeks |
| Perception by Spanish clients | Sometimes seen as less committed | Typically preferred by local counterparties |

How to register a branch office in Spain: step-by-step process
Setting up a branch office in Spain as a UK company involves a fixed sequence of legal and administrative steps that must be completed in the correct order.
- Obtain a NIF for the UK parent company. The foreign entity must obtain a Spanish tax identification number (NIF) from the AEAT before the branch can be registered. Non-EU companies may need to appoint a tax representative for this purpose.
- Apostille and translate the UK company documents. The UK company’s certificate of incorporation, articles of association, and any relevant board resolutions must be apostilled under the Hague Convention and translated into Spanish by a sworn translator.
- Execute a public deed of establishment (escritura pública) before a Spanish notary. This deed establishes the branch, appoints a Spanish resident representative (apoderado), sets out the branch’s activities, and assigns an endowment capital (dotación) to the branch.
- Register the deed in the Mercantile Registry of the province where the branch is located. The branch receives its own registry entry and registration number.
- Obtain the branch NIF. A separate NIF is assigned to the branch as a Spanish taxpayer, distinct from the UK parent’s NIF.
- Register for IVA and other taxes via Modelo 036 if the branch will make taxable supplies in Spain.
- Register employees and payroll with the Spanish Social Security system (TGSS) if the branch will employ staff in Spain.
According to the Spanish Mercantile Registry, foreign companies registered branches at an average rate of over 1,200 new registrations per year between 2019 and 2023, with UK companies historically among the most active foreign registrants before Brexit. Post-Brexit registrations from UK entities have declined, with many opting for SL subsidiaries instead.
Tax treatment when setting up a branch office in Spain as a UK company
The tax implications of setting up a branch office in Spain as a UK company are distinct from those of a subsidiary and must be understood before committing to the structure.
A Spanish branch of a UK company is treated as a permanent establishment (PE) under both Spanish domestic law and the Spain–UK Double Tax Treaty.
The branch’s profits attributable to its Spanish activities are subject to Spanish Corporate Income Tax (Impuesto sobre Sociedades) at the standard rate of 25%.
| Tax item | Branch | Spanish SL subsidiary |
|---|---|---|
| Corporate Income Tax rate | 25% | 25% (23% for SMEs; 15% for qualifying startups) |
| Head-office charge deductibility | Limited; arm’s-length terms required | Transfer pricing rules apply; broader deductibility |
| Profit remittance to the UK | Potential supplementary tax; overridden by Spain–UK DTT | 10% withholding (UK parent ≥10% shareholding) |
| IVA registration | Required if making taxable supplies in Spain | Required if making taxable supplies in Spain |
| Parent-Subsidiary Directive | Not applicable post-Brexit | Not applicable post-Brexit |
Head-office charges, such as management fees, allocated overheads, and intercompany service charges, can be deducted from the branch’s taxable profit, but only if they relate to actual services provided and are priced on arm’s-length terms.
Post-Brexit, the deductibility of certain head-office costs is subject to additional scrutiny, as the AEAT may apply non-EU rules in some contexts rather than the more favourable intra-EU provisions that previously applied.

The apoderado: the branch representative in Spain
Every Spanish branch of a foreign company, including those established for the purpose of setting up a branch office in Spain as a UK company, must appoint at least one apoderado (authorised representative) who is resident in Spain.
The apoderado must have the legal authority to act on behalf of the UK parent in relation to the branch’s Spanish activities.
The apoderado is personally liable for compliance with the branch’s Spanish tax and administrative obligations and must be identified in the public deed of establishment.
The apoderado does not need to be a director of the UK parent company, but they must have sufficient authority to bind the branch contractually and represent it before the Spanish authorities.
Filing obligations of a Spanish branch
A registered Spanish branch has the following principal ongoing obligations:
- Annual Corporate Income Tax return (Modelo 200), filed within 25 days of the six months following the close of the tax year.
- Quarterly IVA returns (Modelo 303) if the branch is registered for IVA.
- Annual deposit of the UK parent’s consolidated accounts in the Mercantile Registry, translated into Spanish.
- Social security and payroll obligations if Spanish employees are engaged.
- Transfer pricing documentation if the branch has related-party transactions with the UK parent exceeding the documentation thresholds.
The obligation to file the UK parent’s accounts in the Spanish Mercantile Registry is one of the most practically burdensome aspects of setting up a branch office in Spain as a UK company, as it requires annual sworn translations of UK financial statements.
| Annual compliance item | Branch | Spanish SL |
|---|---|---|
| Corporate tax return (Modelo 200) | Required | Required |
| Annual accounts deposit | UK parent accounts (sworn translation required) | Own Spanish accounts |
| Quarterly IVA returns (Modelo 303) | Required if IVA-registered | Required if IVA-registered |
| Transfer pricing documentation | Required if transactions exceed €250,000 | Required if transactions exceed €250,000 |
| Board meeting/governance minutes | UK parent governance applies | Spanish SL governance required |
When a branch is preferable to a subsidiary
Despite its disadvantages, setting up a branch office in Spain as a UK company can be more appropriate than a subsidiary in certain situations:
- Short-term or project-based operations in Spain, where incorporating a full subsidiary would be disproportionate.
- Regulated activities where a branch registration is required or preferred by the Spanish regulator.
- Situations where the UK parent wishes to retain direct control without the governance requirements of a Spanish SL.
- Operations where the branch’s losses can be utilised directly against the UK parent’s taxable profits (subject to UK tax rules).
For businesses considering longer-term or higher-volume Spanish operations, an SL subsidiary is generally the preferred structure.
For those considering a holding structure above the Spanish operating entity, our article on establishing a holding company in Spain provides relevant structuring context on how to position both branch and subsidiary vehicles within a wider group.
UK companies exploring cross-border transactions, mergers, or acquisitions as part of their Spanish market entry should also consult our guide to cross-border mergers and acquisitions in Spain, which covers the structural options available to international groups.
Common mistakes when setting up a branch office in Spain as a UK company
The most frequent errors made in the context of setting up a branch office in Spain as a UK company include:
- Failing to apostille UK company documents before presenting them to the Spanish notary delays the registration process significantly.
- Appointing an apoderado without ensuring they fully understand their personal liability for the branch’s Spanish tax compliance obligations.
- Treating the branch as a cost centre without proper transfer pricing documentation for head-office charges creates a risk of AEAT adjustment.
- Omitting to register the branch for IVA before making taxable supplies in Spain.
- Failing to deposit the UK parent’s annual accounts in the Mercantile Registry, which can result in the branch being struck off.
- Not reviewing whether the branch structure remains appropriate as the Spanish operation grows, when switching to an SL subsidiary would become more tax-efficient.

How long does it take to register a branch in Spain?
The full process, from apostilling UK documents through to Mercantile Registry inscription, typically takes between four and eight weeks, depending on the complexity of the UK parent’s corporate documents and the Mercantile Registry’s current workload.
Can a Spanish branch employ staff directly?
Yes.
A Spanish branch can employ staff under Spanish employment contracts, subject to registration with the Spanish Social Security system and compliance with Spanish labour law.
Is a branch or an SL better for a UK company entering Spain?
For most UK companies, an SL subsidiary is preferable due to limited liability, a cleaner tax structure, greater credibility with Spanish counterparties, and more flexibility for future growth.
A branch may be appropriate for short-term or project-based operations, or where the UK parent wishes to retain direct operational control without a separate Spanish governance structure.
