Branch vs Subsidiary in Spain

Most foreign companies expanding into Spain make their structural decision based on just one factor — usually cost or speed. And many end up regretting it within two years. The truth is, choosing between a branch and a subsidiary in Spain affects everything: your taxes, your legal exposure, your ability to attract local clients, and even your exit strategy.

So, which one should you choose? If your priority is limiting legal risk and building a long-term presence, a subsidiary (Sociedad Limitada or S.L.) is the better option for most companies. It creates an independent Spanish entity with its own legal personality, meaning the parent company’s liability is limited to the capital invested. A branch, on the other hand, is simply an extension of the foreign parent — faster to set up, but with no legal separation. The parent company is fully liable for everything the branch does in Spain.

That said, the right answer depends on your specific situation. A branch can be the smarter move in certain scenarios. Let’s break it down so you can make a confident decision.

What is a branch in Spain?

A branch (sucursal) is not a new company. Think of it as an arm of your foreign company reaching into Spain. It operates under the same legal identity as the parent, which means:

• No separate legal personality. The branch and the parent are the same entity in the eyes of Spanish law.
• Unlimited liability. If the branch generates debts or legal problems, the parent company is directly responsible.
• Limited to the parent’s corporate purpose. The branch can only do what the parent company’s statutes allow.
• Requires a branch director (gerente) registered with the Mercantile Registry with full authority to represent the branch.

Setting up a branch requires a notarial deed, registration with the Mercantile Registry, and obtaining a Spanish Tax Identification Number (NIF). The branch must also file annual accounts.

What is a subsidiary in Spain?

A subsidiary (filial) is a brand-new, independent Spanish company. The most common form is the Sociedad de Responsabilidad Limitada (S.L.), which offers the best balance of flexibility and protection. Key features:

• Separate legal personality. The subsidiary is its own entity under Spanish law, completely distinct from the parent.
• Limited liability. The parent company’s risk is capped at the capital it contributed. Since 2022, you can incorporate an S.L. with as little as €1 in share capital.
• Full autonomy. The subsidiary can have a different corporate purpose than the parent, hire independently, and build its own brand in Spain.
• Easier to sell or restructure. If you ever want to bring in investors or sell your Spanish operations, transferring shares in an S.L. is much simpler.

Tax differences: branch vs subsidiary in Spain

Taxation is often the deciding factor. Here is a clear comparison:

Branch taxation:

• Taxed under the Non-Resident Income Tax (IRNR), generally at a rate of 24% on net profit attributable to Spain.
• Profits sent back to the parent may face an additional branch profit tax of 19%, unless reduced by a Double Taxation Treaty.
• Payments from the branch to its head office (royalties, commissions, management fees) are generally not deductible.
• Losses can often be offset against the parent company’s profits in its home country — a significant advantage during the early years of operation.

Subsidiary taxation:

• Taxed under Corporate Income Tax (Impuesto sobre Sociedades) at the standard rate of 25%. SMEs with turnover under €1 million benefit from reduced rates (21% on the first €50,000 in 2025).
• Dividends paid to an EU parent company can be exempt from withholding tax under the EU Parent-Subsidiary Directive, provided the parent holds at least 5% of shares.
• The subsidiary can access Spain’s network of over 100 double taxation treaties.
• Eligible for the ETVE regime (holding company structure), which can offer up to 95% exemption on dividends and capital gains from foreign subsidiaries.

When to choose a branch

A branch may be the better option if:

• You expect significant losses in the first years and want to offset them against the parent company’s profits at home.
• Your presence in Spain will be limited — a representative office, a small team, or a specific project with a defined timeline.
• You want a lighter administrative structure and don’t need legal separation from the parent.
• Your home country has a favorable tax treaty with Spain that eliminates or reduces the branch profit tax.

When to choose a subsidiary

A subsidiary is typically the right choice if:

• You want to protect the parent company from Spanish liabilities. This is critical for companies in sectors with high commercial, employment, or product risk.
• You plan to build a full-scale operation — hiring staff, holding assets, signing significant contracts, and growing a local client base.
• You want to build a local brand. Spanish clients, banks, and suppliers tend to trust a locally incorporated company more than a foreign branch.
• Tax efficiency matters. Especially for EU parent companies, the combination of the Parent-Subsidiary Directive and Spain’s treaty network makes the subsidiary structure hard to beat.
• You may want to sell the Spanish business or bring in local investors in the future.

FAQ: common questions about branch and subsidiary in Spain

Can I convert a branch into a subsidiary later? 

Yes. This is done through a process called «contribution of a branch of activity» (aportación de rama de actividad), where the branch’s assets and liabilities are transferred to a newly incorporated S.L. However, it involves legal and tax complexity, so it is better to choose the right structure from the start.

Which one is faster to set up? 

Both require similar steps: notarial deed, Mercantile Registry inscription, and NIF. The timeline is comparable — typically 4 to 8 weeks. The subsidiary requires defining share capital and appointing administrators, but these are straightforward.

Do both need to file annual accounts? 

Yes. Both branches and subsidiaries must file annual accounts with the Mercantile Registry and comply with Spanish tax obligations, including quarterly VAT returns.

What about the minimum capital requirement? 

A branch has no capital requirement. A subsidiary (S.L.) can be incorporated with just €1 since the reform introduced by Law 18/2022, making this a non-issue.
