How to Start a Branch Office in Spain: Requirements, Costs & Process

Expanding into Spain can be an effective way for an established foreign company to build a presence in the European market. If you are researching how to start a branch office in Spain, it is important to understand how a Spanish branch differs from a separate Spanish company.

A branch office in Spain, as a “sucursal,” is a secondary business unit of a foreign parent company. It may conduct part or all of the operations of its parent company in Spain; it has permanent representation and a certain management autonomy, but it does not have legal personality separate from the parent company. A branch shall also be registered at the appropriate Mercantile Registry.

For foreign companies, setting up a branch can provide a formal structure for conducting business activities in Spain without incorporating a completely separate subsidiary. This guide explains how to open a branch in Spain, including the legal requirements, registration process, tax implications, estimated costs, banking considerations, business address requirements, and ongoing compliance.

What Is a Branch Office in Spain?

A branch office in Spain, or a sucursal, is a secondary place of business in which a foreign parent company carries on all or part of its business activities in Spain. Unlike a Spanish subsidiary, a branch does not have separate legal personality. It is still legally linked with the foreign parent company, which usually will continue to be responsible for the obligations of the branch.

The Spanish government states that a branch has a permanent presence and has a degree of management autonomy but does not have legal personality separate from its parent company. Its public deed must be registered with the appropriate Provincial Mercantile Registry.

Key features of a Spanish branch

• No separate minimum share capital is generally required to establish the branch.
• The branch is a part of the foreign parent company.
• Does not have legal personality.
• The foreign parent is usually responsible for the obligations of the branch.
• It can conduct business activities within its registered scope and is subject to applicable licenses and regulations.
• It requires registration with the Mercantile Registry.
• It has Spanish tax and accounting obligations.
• A representative must be appointed for the branch.
• It can employ staff and enter into commercial contracts when permitted by its activities.
• A registered branch is generally treated as a permanent establishment for Spanish tax purposes.

Branch Office vs Permanent Establishment

A branch office and a permanent establishment (PE) are closely related but are not exactly the same concept. For tax purposes, a registered branch is generally one form of permanent establishment. However, a permanent establishment can also arise in other circumstances under Spanish domestic law or an applicable tax treaty.

This distinction is important because the tax treatment of a foreign company operating in Spain can depend on whether it has created a permanent establishment and how that establishment is structured.

What Are the Legal Requirements for Setting Up a Branch Office in Spain?

Registering a branch in Spain involves corporate documentation, authentication of foreign documents, appointment of a representative, notarial formalities, Mercantile Registry registration, and tax compliance.

The exact requirements can vary depending on the parent company’s country of incorporation, legal structure, and intended activities.

1. Parent Company Documentation

The foreign parent company will generally need documentation demonstrating its legal existence and authority to establish the Spanish branch.

Depending on the circumstances, documents may include:

• Certificate of Incorporation or equivalent registration document
• Articles of Association or constitutional documents
• Current company registration details
• Certificate of Good Standing, where applicable
• Board or shareholder resolution approving the Spanish branch
• Appointment of the branch representative
• Power of attorney, where applicable

Foreign corporate documents may need to be apostilled or legalised and translated into Spanish by an authorised/sworn translator, depending on their country of origin and the applicable requirements.

2. Appoint a Branch Representative

The branch needs an appropriately appointed representative who can act on its behalf. The representative’s identity and authority must be properly documented. An NIE (Número de Identidad de Extranjero) may be required depending on the person’s circumstances and the procedure being completed.

For tax identification purposes, the Spanish Tax Agency identifies a foreign company’s branch as a Branch (W) and requires supporting documentation concerning the branch’s registration and representative.

3. Spanish Registered Address

A branch requires an address in Spain for registration and official communications.

Depending on the business model, the company may consider:

• Commercial premises
• Business centres
• Coworking facilities
• Suitable registered or virtual office arrangements

The chosen address should be appropriate for the branch’s activities and any applicable local licensing requirements.

4. Public Notarial Deed

The establishment of the branch is formalised through a public deed before a Spanish notary.

The deed generally includes information such as:

• Details of the foreign parent company
• Decision to establish the Spanish branch
• Branch address
• Activities to be carried out
• Representative details
• Powers granted to the representative
• Relevant corporate documentation

5. Mercantile Registry Registration

The branch establishment deed must be submitted to the relevant Registro Mercantil. Registration is a key part of formally establishing the branch in Spain. The Spanish government’s business guidance confirms that a sucursal requires registration of its public deed with the Provincial Mercantile Registry.

6. Tax and Other Registrations

After the branch has been established, the applicable registrations and tax formalities must be completed.

Depending on the business activity, these can include:

• Tax identification and census registration
• Corporate/non-resident tax formalities
• VAT registration
• Economic Activity Tax (IAE)
• Social Security registration if employees are hired
• Sector-specific licenses or permits

Not every branch will have identical tax or licensing requirements, so these should be determined according to the actual business activity.

How Do I Open a Branch Office in Spain?

If you are looking for how to start a branch office in Spain, the process can generally be organised into the following steps.

Step 1: Approve the Establishment of the Branch

The foreign parent company should formally approve the creation of its Spanish branch.

The corporate resolution may cover:

• Establishment of the branch
• Business activities
• Spanish address
• Appointment of the representative
• Powers granted to the representative

The exact approval procedure depends on the company’s legal structure and governing documents.

Step 2: Prepare and Legalise Corporate Documents

Collect the required documents from the foreign parent company.

Where applicable:

1. Obtain certified copies.
2. Apostille or legalise the documents.
3. Arrange Spanish sworn translations.
4. Prepare the documentation required by the Spanish notary and Mercantile Registry.

The time required for this stage depends heavily on the parent company’s country of incorporation and the documents involved.

Step 3: Obtain the Required Identification Numbers

The representative may need an NIE, while the foreign company and Spanish branch require the appropriate tax identification arrangements.

For a registered foreign-company branch, the Spanish Tax Agency uses the NIF category W. The documentation for this type of NIF includes information concerning the branch’s public deed, Mercantile Registry registration, and representative.

Step 4: Execute the Branch Establishment Deed

The branch establishment deed is executed before a Spanish notary.

Under certain conditions, a power of attorney might permit some procedures to be carried out by a representative. However, whether a particular step can be completed remotely depends on the notary, documentation, and circumstances of the case.

Step 5: Register the Branch with the Mercantile Registry

Submit the notarised documentation to the relevant Mercantile Registry. After the registration has been completed, the branch is formally recorded as a Spanish branch.

Step 6: Complete Tax Registrations

The branch must complete the tax formalities applicable to its activities.

These may include:

• Tax census registration
• NIF
• VAT
• Economic Activity Tax
• Corporate or non-resident tax obligations
• Other applicable registrations

The Spanish Tax Agency provides specific filing procedures for permanent establishments, including corporate tax and non-resident tax forms.

Step 7: Set Up the Branch’s Operations

Once the registration and tax formalities are addressed, the company can organise its Spanish operations. If the branch hires employees, the applicable employer and Social Security registrations must also be completed.

What Are the Tax Implications of Having a Branch Office in Spain?

Tax is an important consideration when setting up a branch in Spain. A Spanish branch is generally treated as a permanent establishment of the foreign company for Spanish tax purposes and is generally taxed on the income attributable to that establishment.

1. Corporate Income Tax Treatment: A branch operating as a permanent establishment is generally subject to Spanish taxation on its taxable income attributable to the Spanish establishment. The general tax rate is generally 25%, although the applicable regime depends on the company’s circumstances and current legislation.
2. Deductible Business Expenses: Expenses connected with the Spanish permanent establishment may generally be considered when calculating taxable income, subject to Spanish tax rules. Special restrictions may apply to certain payments, management expenses, and internal charges between the branch and its foreign head office.
3. VAT in Spain: VAT obligations depend on the branch’s activities and transactions. Spain’s standard VAT rate is generally 21%, although reduced rates and exemptions may apply.
4. A branch should determine whether VAT registration is required, which rates apply, whether input VAT can be recovered, and the applicable filing frequency.
5. Double Taxation Treaties: The foreign parent company’s country may have a Double Taxation Agreement (DTA/DTT) with Spain. The applicable treaty can affect the definition of a permanent establishment, profit allocation, taxation rights, relief from double taxation, and certain withholding or additional tax rules.
6. Tax on Certain Transfers to the Head Office: Spanish rules provide for an additional tax on certain amounts transferred abroad by permanent establishments of non-resident entities, subject to applicable exemptions and treaty provisions. This should be reviewed as part of the company’s international tax structure.
7. Accounting and Tax Reporting: A Spanish branch has accounting, tax, and formal compliance obligations, which may include:
   1. Corporate/non-resident tax returns
   2. VAT returns, where applicable
   3. Accounting records
   4. Parent-company financial statements
   5. Mercantile Registry obligations
   6. Payroll and Social Security compliance where employees are hired

The Spanish Tax Agency provides specific tax forms for permanent establishments, including Model 200/206 and applicable installment-payment procedures.

How Much Does It Cost to Open a Branch Office in Spain?

The cost of opening a branch in Spain depends on the parent company’s country, the number of documents involved, legalisation and translation requirements, professional services, and the complexity of the proposed business activity.

A branch generally does not require a separate minimum share-capital contribution in the same way as a Spanish subsidiary. However, establishing a branch still involves several administrative, legal, and operational costs.

Main Cost Categories

These figures are indicative rather than fixed fees. The final cost can vary significantly depending on the parent company’s jurisdiction, the number of documents requiring legalisation and translation, the professional services required, and the branch’s business activity.

Can I Open a Business Bank Account for a Spanish Branch Remotely?

A Spanish branch may need a business bank account for its day-to-day operations, but banking requirements are determined by the individual bank.

A bank may assess:

• Parent company’s country
• Ownership structure
• Ultimate beneficial owners
• Business activity
• Expected transaction volume
• Source of funds
• Representative
• Corporate documents
• Tax residence
• KYC and AML requirements

Some Spanish banks may offer remote or partially remote onboarding, while others may require an in-person appointment or additional verification. Therefore, remote bank account opening is possible in some circumstances but should not be treated as guaranteed. A company should also distinguish between the legal requirements for registering a branch and the additional requirements imposed by its chosen bank.

Branch Office vs Subsidiary in Spain: Which Should You Choose?

A branch and a Spanish subsidiary can both provide a foreign company with a presence in Spain, but they have different legal structures.

How to Get a Local Business Address for a Spanish Branch Office?

A Spanish branch needs an appropriate registered address for registration and official communications.

The most suitable option depends on the company’s activities and whether its business requires physical premises.

1. Virtual or Registered Office

A suitable virtual office address in Spain can provide a professional address and mail-handling services, subject to the provider’s terms and applicable registration requirements.

2. Coworking Space

A coworking space can provide:

• Workspace
• Meeting rooms
• Business facilities
• Networking opportunities
• Potential address services

3. Business Centre

A business centre may provide:

• Office facilities
• Reception services
• Meeting rooms
• Mail handling
• Professional business premises

4. Commercial Office

A dedicated commercial office can be appropriate for businesses that:

• Hire employees
• Meet customers
• Hold inventory
• Conduct physical operations
• Require dedicated premises

If the business activity is regulated, the company should confirm whether the selected premises meet the relevant licensing and local requirements.

What Ongoing Compliance Does a Spanish Branch Have?

Registering the branch is only the beginning of its Spanish compliance obligations.

Depending on the business, ongoing requirements may include:

• Maintaining accounting records
• Filing applicable tax returns
• VAT compliance
• Maintaining corporate information
• Filing or maintaining parent-company financial documentation
• Mercantile Registry obligations
• Payroll compliance
• Social Security
• Business licenses
• Updating representative or registered-office information

If the branch employs workers, the relevant employer and employee Social Security requirements must be addressed.

Companies should also monitor changes to the parent company’s corporate information that may affect the Spanish branch.

What Are the Advantages of Opening a Branch Office in Spain?

A Spanish branch can provide several benefits for an established foreign company.

• Direct connection with the parent company: The branch remains directly connected to the foreign parent rather than becoming an entirely separate Spanish company.
• No separate minimum share capital: A branch generally does not require a separate minimum share capital contribution simply to establish the branch.
• Formal Spanish presence: A registered branch gives the foreign company a formal structure through which it can conduct qualifying business activities in Spain.
• Local operations: Depending on its activities, a branch can support local contracts, employees, customers, suppliers, and commercial operations.
• Potentially suitable for international expansion: For companies that want their Spanish operations to remain integrated with their existing international business, a branch can be an alternative to incorporating an SL subsidiary.

What Are the Disadvantages of a Spanish Branch?

A branch is not automatically the best structure for every foreign company.

Potential disadvantages include:

• The parent company generally remains responsible for the branch’s liabilities.
• The branch has Spanish tax and accounting obligations.
• Parent-company documents may need to be maintained and submitted.
• International tax and profit-attribution rules can be complex.
• Banking and KYC requirements may still be extensive.
• Certain activities may require specific licenses or premises.
• A subsidiary may offer more separation of Spanish operations and the foreign parent.

A company should compare both structures before deciding which one fits its long-term objectives.

Can a Foreign Company Open a Spanish Branch Remotely?

Some parts of the branch setup process may be handled remotely through powers of attorney and professional representatives. However, not every procedure can necessarily be completed remotely.

Remote processing can depend on:

• Notarial requirements
• Power of attorney
• Identity verification
• NIE procedures
• Foreign-document requirements
• Mercantile Registry requirements
• Bank KYC procedures

Banking requirements in particular can differ significantly between financial institutions.

Therefore, foreign companies should confirm the remote requirements for each stage instead of assuming that the entire branch-registration process can be completed online.
