Setting Up a Business in Spain: 4 Key Issues for International Investors

Spain offers an attractive platform for international businesses looking to establish a presence in Europe. However, setting up a company involves more than signing a deed before a notary. Foreign shareholders and directors may need to deal with additional documentation, banking compliance, tax registrations and ongoing corporate obligations.

In many cases, the incorporation itself is not the main challenge. The real challenge is ensuring that all the elements needed for the company to operate are ready at the right time.

1. Foreign documentation: one of the first potential bottlenecks

International shareholders and directors often need to provide documentation that is issued outside Spain. Depending on the circumstances, this may include NIE numbers, powers of attorney, corporate certificates, board resolutions and evidence of ownership.

Foreign documents may also need to be notarised, apostilled or legalised and accompanied by sworn translations. Original documents may need to be delivered to Spain before certain procedures can be completed.

This means that documentation can become one of the main factors affecting the incorporation timeline.

A good starting point is to identify all required documents before the process begins and establish a clear checklist covering signing, apostilles or legalisation, translations and delivery of originals.

The ownership structure also deserves particular attention when a foreign company is involved as a shareholder. Spanish banks, notaries and authorities need to understand who ultimately owns or controls the structure. A clear ownership chart and identification of the ultimate beneficial owners (UBOs) can help avoid additional questions and delays.

 

2. Banking and AML/KYC: more than just opening an account

For an international business, opening a corporate bank account is an essential part of becoming operational in Spain. However, banking should not be treated as a simple administrative step after incorporation.

Banks must perform AML/KYC checks and may request detailed information about the shareholders, ownership structure, source of funds and expected business activity.

Depending on the company and its structure, the bank may ask for information such as:

• Source of funds and source of wealth.
• Shareholders and ultimate beneficial owners.
• Expected turnover and transaction volumes.
• Countries and currencies involved.
• Customers and suppliers.
• Business plan, contracts or website.

The key is consistency. The information provided to the bank should make sense alongside the company’s corporate purpose, tax registration and expected activity.

Preparing this information in advance can make the banking process more predictable and prevent the company from being incorporated but unable to operate normally because its banking arrangements are still pending.

3. Tax and operational registrations should be planned from the beginning

Once the company has been incorporated, several steps are required before it can operate effectively.

These may include obtaining the definitive NIF, completing the relevant tax registrations, setting up VAT obligations, obtaining digital certificates and addressing Social Security requirements.

The company’s tax profile should accurately reflect its real business activity. This includes its business activity, tax domicile, VAT status, corporate tax and withholding obligations and, where relevant, intra-EU operations.

VAT planning is particularly important for companies providing services or selling goods across European borders. Depending on the activity and transactions involved, ROI/VIES registration may be required before carrying out certain intra-community operations.

Digital administration is another practical consideration. Company and representative certificates are used for electronic filings and communications with Spanish public authorities. Electronic notifications therefore need to be monitored and assigned to someone within the organisation from the outset.

The objective is not simply to have a company registered, but to have a fully activated operating structure.

4. Incorporation is the beginning of the compliance cycle

A newly incorporated company immediately becomes subject to ongoing accounting, tax and corporate obligations.

Depending on its activity and structure, these may include accounting records, VAT and withholding tax filings, Corporate Income Tax, corporate books, annual accounts, payroll and Social Security obligations and electronic notifications.

These responsibilities should be considered when planning the incorporation itself. A company that has been correctly incorporated can still face compliance issues if its first-year obligations have not been identified and assigned.

Creating a first-year compliance calendar is therefore a practical way to establish responsibilities and deadlines from the beginning.

Ultimately, the incorporation process should be approached as a project with several interconnected workstreams: corporate, tax, banking, accounting and operational. Coordinating them from the start can help international investors avoid unnecessary delays and build a more predictable path to doing business in Spain.

From incorporation to operational readiness

For international entrepreneurs, understanding the incorporation process is important, but understanding what happens before and after the incorporation deed can be just as relevant.

This is precisely the approach that Daniel Gil Boronat, Director of the Accounting Business Unit at Adlanter, will explore in the upcoming webinar: How to Incorporate a Company in Spain.

The session will take place online on 30 September 2026 at 4:00 p.m. (CEST) and will be delivered entirely in English.

The webinar will provide a practical overview of the incorporation journey, including foreign documentation, NIEs and powers of attorney, banking and AML/KYC, ownership structures and UBOs, tax and VAT registrations, Social Security and ongoing compliance.
