Spain is one of the most attractive destinations for foreign investors within the European Union. Its strategic location, access to the European market, quality of life, real estate sector, tourism, renewable energy, technology, and business environment lead many international investors to consider establishing themselves or investing in the country.
However, before investing in Spain, it is important to understand the main legal, tax, and administrative aspects that may affect the transaction.
1. Spain Allows Foreign Investment, but There Are Formal Obligations
As a general rule, Spain maintains a favorable regime for foreign investment. Nevertheless, certain investments made by non-resident individuals or legal entities may be subject to filings with the Foreign Investment Registry or, in some cases, prior authorization.
Since September 1, 2023, the foreign investment regime has been mainly regulated by Royal Decree 571/2023, of July 4, on foreign investments, which replaced the previous regime under Royal Decree 664/1999.
In general terms, foreign investments in Spain include, among others:
- The acquisition of shares or equity interests in Spanish companies when the non-resident investor reaches at least 10% of the share capital or voting rights.
- The incorporation of a Spanish company by a non-resident investor.
- The opening or expansion of branches in Spain.
- Certain intragroup financing transactions above certain thresholds.
- The acquisition of real estate in Spain by non-residents when the amount exceeds €500,000.
2. Choosing the Right Investment Structure
One of the first decisions is how the investment will be structured. The most common forms are:
Direct Investment in a Spanish Company
The investor may incorporate a company in Spain or acquire shares in an existing company. The most commonly used corporate form is the Private Limited Company (Sociedad de Responsabilidad Limitada or S.L.), especially for small and medium-sized businesses.
Real Estate Acquisition
Spain is a very active market for real estate investment, both residential and commercial. Before purchasing, it is advisable to review the property’s registry status, urban planning status, tax situation, and lease arrangements.
Branch or Permanent Establishment
Foreign companies may also operate in Spain through a branch. This option may be useful when the foreign parent company wishes to maintain its legal personality, although it involves accounting, tax, and registration obligations in Spain.
Joint Venture or Collaboration Agreements
In some sectors, it may be advisable to partner with a local counterpart through a joint company, shareholders’ agreement, or business collaboration agreement.
3. Sensitive Sectors and Prior Authorization
Although foreign investment is broadly liberalized, there are sectors in which prior administrative authorization may be required, especially when the investment affects public order, public security, or public health.
Law 19/2003, of July 4, as amended in recent years, provides specific controls for certain foreign direct investments in strategic sectors.
The sectors that may require special analysis include:
- Critical infrastructure.
- Energy.
- Transport.
- Water.
- Healthcare.
- Communications.
- Media.
- Data processing or storage.
- Critical technologies.
- Artificial intelligence, robotics, semiconductors, cybersecurity, or biotechnology.
- Defense and dual-use products.
- Supply of key inputs.
- Sectors with access to sensitive information or personal data.
Therefore, before closing a transaction, it is advisable to analyze whether the investment is subject to prior authorization or only to a post-investment filing.
4. Identification and Anti-Money Laundering Obligations
Investment transactions in Spain usually require full identification of the investor, the source of funds, and, in the case of companies, their beneficial owners.
Spanish anti-money laundering regulations require banks, notaries, lawyers, tax advisers, and other obliged entities to verify the client’s identity and the origin of the funds.
This may involve providing documentation such as:
- Passport or identity document.
- Foreigner Identification Number (NIE), where applicable.
- Corporate certificates.
- Articles of incorporation or bylaws of the foreign company.
- Beneficial ownership certificate.
- Evidence of the source of funds.
- Apostilled or legalized documents, where applicable.
Preparing this documentation in advance helps avoid delays in the transaction.
5. Taxation of Investment in Spain
Taxation is one of the most important aspects to analyze before investing.
Depending on the type of investment, different taxes may apply:
- Corporate Income Tax, if the investment is made through a Spanish company.
- Non-Resident Income Tax, if the investor is not tax resident in Spain.
- VAT or Transfer Tax, in real estate transactions.
- Stamp Duty, in certain notarized documents.
- Wealth Tax or the Temporary Solidarity Tax on Large Fortunes, where applicable.
- Taxation on dividends, interest, capital gains, or rental income.
In addition, if the investor resides in another country, it is necessary to analyze whether a double tax treaty exists between Spain and the investor’s country of residence.
6. Real Estate Investment: Issues That Should Be Reviewed
When purchasing property in Spain, it is advisable to carry out a prior due diligence. Some key points are:
- Registered ownership of the property.
- Existence of charges, mortgages, attachments, or easements.
- Urban planning status.
- Licenses.
- Occupancy or existing leases.
- Community fees.
- Outstanding taxes.
- Energy certificates.
- Possible limitations if the asset is rural land, a tourist property, or subject to regional or municipal regulations.
Foreign buyers will also normally need an NIE, a Spanish bank account, and properly documented funds.
7. Incorporation of Companies in Spain
To incorporate a company in Spain, the following steps are normally required:
- Apply for the company name certificate.
- Obtain NIE or tax identification numbers for shareholders and directors, where applicable.
- Open a bank account or provide evidence of the contribution of share capital.
- Prepare the bylaws.
- Execute the public deed before a notary.
- Obtain the provisional and final tax identification number (NIF).
- Register the company with the Commercial Registry.
- Register the business activity with the Spanish Tax Agency.
- Comply with labor and Social Security obligations if employees are hired.
The chosen structure should be adapted to the type of business, investment volume, shareholders, financing, and tax strategy.
8. Foreign Documents: Apostille, Legalization, and Powers of Attorney
When the investor acts from abroad, it is common to use powers of attorney executed outside Spain. In such cases, the document must meet validity requirements, legalization or apostille requirements, and, in some cases, sworn translation.
In addition, the Spanish notary must assess whether the foreign power of attorney is equivalent and sufficient to carry out the relevant legal act in Spain.
For this reason, it is advisable to prepare powers of attorney with Spanish legal advice from the outset, in order to avoid the document being rejected at signing.
9. Residence and Investment
Investing in Spain does not automatically grant residence. However, certain investors may consider specific immigration routes, especially if they make significant investments or wish to relocate to the country.
Tax residence and administrative residence are not the same. A person may have authorization to live in Spain, but tax residence will depend on criteria such as days spent in Spain, the center of economic or family interests, and the rules of applicable international treaties.
10. The Importance of Prior Planning
Investing in Spain can be an excellent opportunity, but it requires planning. Before carrying out the transaction, it is advisable to analyze:
- Who is investing: an individual, foreign company, holding company, or Spanish vehicle.
- What asset is being acquired: company, property, business, shareholding, or financing.
- Amount of the investment.
- Country of residence of the investor.
- Source of funds.
- Economic sector.
- Entry, holding, and exit taxation.
- Filing or authorization obligations.
- Legal, urban planning, labor, or regulatory risks.
Proper planning helps reduce risks, optimize the tax structure, and avoid delays with notaries, banks, registries, or public authorities.
Conclusion
Spain offers an attractive framework for foreign investment, but each transaction must be analyzed individually. Regulations on foreign investments, taxation, anti-money laundering, companies, real estate, and strategic sectors may significantly affect the structure and execution of the investment.
Obtaining legal and tax advice from the outset allows investors to invest with greater certainty, anticipate obligations, and design an efficient structure.
