Are you considering expanding your US business into Europe? Thanks to its strategic location, EU membership, excellent quality of life, and cultural ties with America, Spain is a top destination for entrepreneurs seeking growth beyond the US.

In this article, we’ll guide you through every step with clarity, confidence, and a practical approach. Let’s get started!

Branch or subsidiary in Spain: Which is right for your type of business?
Before diving into the process, there’s a key decision to make: should you open a branch or a subsidiary? While they may seem similar, they’re quite different.
A branch is essentially an extension of your US company. It does not have its own legal personality, meaning it remains legally and fiscally dependent on the parent company. A subsidiary, on the other hand, is a new company incorporated in Spain, with its own legal identity—even if it’s fully owned by your US business.
So, which one suits you best? That depends on your goals.
When to choose a branch
A branch is ideal if:
- You want to keep operations simple without forming a new company.
- Your activity in Spain will be limited or temporary.
- You don’t need to separate your US and Spanish assets.
- You want fast market entry with minimal upfront investment.
Keep in mind that since a branch has no legal personality of its own, the US parent company is fully liable for all branch activities. It may also face restrictions in accessing certain local benefits or subsidies.
When to choose a subsidiary
A subsidiary is more suitable if:
- You plan a long-term presence with operational and legal independence.
- You intend to hire local employees, issue invoices under your own name, and operate autonomously.
- You want to apply for Spanish or EU funding.
- You plan to scale your brand or open multiple units.
Although setting up a subsidiary (such as a Sociedad Limitada or SL) involves more formalities, it provides greater control, legal protection, and visibility within the European market.
Legal requirements for opening a branch or subsidiary in Spain as a foreign company
Once you’ve chosen the structure, you’ll need to comply with Spain’s legal requirements. The process is well-defined but does require organization and several essential documents.
Both structures must be registered with the Commercial Registry, obtain a corporate tax ID (CIF), and appoint a legal representative residing in Spain. However, the specific requirements vary based on whether you’re opening a branch or a subsidiary.
Requirements for opening a branch of your US company in Spain
- Deed of incorporation of the parent company, duly apostilled and translated.
- Current Certificate of Good Standing from the US.
- Resolution from the parent company’s governing body approving the branch’s creation.
- Appointment of a legal representative in Spain (can be a manager or trusted individual).
- Notarized public deed in Spain and registration with the Commercial Registry.
- CIF (corporate tax ID) issued by the Spanish Tax Agency.
A branch can operate with just these steps. However, unless properly structured, it may not be allowed to hire employees directly or engage in certain local activities.
Requirements for opening a subsidiary (limited company) of your US company in Spain
- Obtain NIEs (foreigner ID numbers) for non-resident shareholders or directors.
- Deposit the minimum share capital (€3,000 for an SL) in a Spanish bank.
- Draft the company’s bylaws (articles of association).
- Sign the public deed of incorporation before a Spanish notary.
- Register with the Commercial Registry in the relevant province.
- Apply for a CIF and register with the Tax Authorities.
Though more involved, a subsidiary offers greater operational flexibility and commercial legitimacy. Being a Spanish-registered entity also boosts your credibility with local clients and authorities.

Tax considerations: how branches and subsidiaries are taxed in Spain
Taxes are another crucial aspect. Spain’s tax system differs from that of the US, and understanding how it applies to your structure is essential. Tax missteps can be costly, so getting it right from the start is key.
Taxation of a branch
- The branch is taxed only on profits generated in Spain—not globally.
- It lacks legal personality but must maintain separate accounting records.
- It pays Spanish corporate income tax at a rate of 25% on net profits.
- The US parent may owe tax on these profits unless the US–Spain double tax treaty is correctly applied.
- Quarterly tax filings, local bookkeeping, and full compliance with Spanish regulations are required.
Taxation of a subsidiary
- The subsidiary is treated as a local Spanish company for tax purposes.
- It is subject to corporate tax (25%), VAT (21%), and other applicable taxes.
- It may qualify for local tax deductions, allowances, and incentives.
- Dividends paid to the US parent may benefit from the US–Spain tax treaty to avoid double taxation.
- If you’re planning a stable and profitable operation in Spain, a subsidiary often offers more favorable tax efficiency.
Administrative procedures for starting to operate with a foreign company in Spain
Once the legal and tax frameworks are in place, you’re ready to begin operations in Spain. This includes setting up your infrastructure, opening bank accounts, hiring staff, and securing licenses if required. Below are the necessary steps:
Registration with the tax authorities and social security
Both branches and subsidiaries must register with:
- The Tax Agency: to manage tax filings and obtain the final CIF.
- The General Social Security Treasury: if employing staff, you’ll need to request a Contribution Account Code (CCC).
This allows you to issue invoices, file taxes, and process payroll legally.
Bank account in Spain and direct debit
Having a Spanish bank account is mandatory for business operations. To open one, you’ll need:
- Provisional or final CIF
- Deed of incorporation
- NIE of the legal representative
- Proof of address or business activity
Your business account will be essential for receiving payments, handling payroll, managing supplier payments, and complying with tax obligations. Choose a bank experienced in working with foreign businesses.
Strategic tips for successful business expansion in Spain as an American
Beyond compliance, international expansion requires strategy. Spain presents great opportunities—but with its own cultural, commercial, and regulatory nuances.
Getting this right from the beginning can make all the difference.
Rely on local experts from the outset
Hiring a local legal and tax advisor with experience in international business is crucial. They’ll guide you through the regulatory landscape and help you benefit from available incentives.
It’s also advisable to work with a Spanish accountant, particularly if you’re not residing in Spain full-time.
Invest in building relationships and networking
Business in Spain thrives on relationships. Attend local events, trade shows, or join organizations like the American Chamber of Commerce in Spain to build valuable connections.
Many regional governments also offer support programs for foreign investors—including financial aid, advisory services, and introductions to suppliers and business networks.
Take your US business to the next level with a presence in Spain
Expanding your US business into Spain is more than just an opportunity—it’s a strategic gateway to the European market.
Whether you opt for a branch to test the waters or a subsidiary to build a long-term presence, the key is clarity, compliance, and trusted support from day one.
