How Do I Open a Branch Office in Spain? 

Establishing a branch office in Spain requires various legal and administrative processes. Here is a clear, well-structured process to help you complete the setup smoothly and efficiently.

Step 1: Prepare and Legalize Your Corporate Documents

Begin by collecting all the required documents from your foreign parent company:

• Certificate of Incorporation
• Articles of Association
• Certificate of Good Standing
• Board Resolution authorizing the Spanish branch
• Appointment of the branch representative

Once collected, complete the following:

• Notarize the documents
• Apostille or legalize them (Hague Convention)
• Translate them into Spanish by a Sworn Translator

This ensures the documents are legally valid in Spain.

Step 2: Obtain NIE for the Representative & NIF for the Parent Company

Spain requires tax identification for both the company and its representative:

• The foreign company must obtain a NIF (Número de Identificación Fiscal)
• The branch representative has to acquire an NIE (Foreigner Identification Number)

You can apply for both:

• Inside Spain
• Through a Spanish Consulate abroad
• Via Power of Attorney, allowing full remote handling

Step 3: Sign the Branch Establishment Deed Before a Notary

The branch office is officially created by signing a Notarial Deed of Establishment (Escritura de Apertura de Sucursal).

During this notarial appointment, the following are declared:

• Intention to open a Spanish branch
• Registered address in Spain
• Identity of the appointed legal representative
• Corporate details of the parent company

This deed formally establishes your branch under Spanish law.

Step 4: Register the Branch with the Mercantile Registry

Submit the notarized deed to the Mercantile Registry (Registro Mercantil).

After review and approval, the branch becomes officially:

• Recognized
• Legally active
• Eligible to operate throughout Spain

This registration gives your branch full legal standing.

Step 5: Register with the Spanish Tax Authority 

Your branch must be activated for taxation purposes. This includes registration for:

• Corporate Income Tax (CIT)
• VAT (IVA)
• Economic Activity Code (IAE)
• Social Security, if you plan to hire employees

This step ensures your branch can invoice, receive payments, and operate legally.

Step 6: Open a Corporate Bank Account in Spain

A Spanish bank account is required for:

• Running day-to-day operations
• Paying suppliers
• Managing payroll
• Paying taxes

Many banks allow remote account opening through Power of Attorney, while some may require a brief in-person visit.

A branch office in Spain must comply with Spanish tax rules. Here’s what you need to know:
