Answers to common questions from foreign founders about registering a company in the Basque Country, covering legal forms, incorporation steps, capital, banking, taxation basics and ongoing compliance.

Basque Company Registration: Common Questions Answered

For foreign founders considering Spain, the Basque Country is often mentioned as a distinct option. It has its own tax regime, its own business support bodies and a strong industrial and services base. This article answers the questions that come up most often when founders ask about registering a company in the Basque Country. It is general information only and is not legal, tax or investment advice; rules change and individual circumstances differ, so confirm details with qualified local professionals before acting.

Where exactly is the company registered?

The Basque Country is an autonomous community within Spain, made up of three historical territories: Bizkaia, Gipuzkoa and Araba (Álava). Company registration in the Basque Country is still governed by Spanish company law. The regional difference lies mainly in taxation, which is administered by the regional tax authorities (the provincial treasuries, or Haciendas Forales) under the Basque Economic Agreement, and in the local business ecosystem.

Which legal form should a foreign founder choose?

Most foreign founders choose between a few common structures:

• Sociedad Limitada (S.L.) — the standard private limited company, widely used by small and medium businesses and the usual choice for a first subsidiary.
• Sociedad Anónima (S.A.) — a joint-stock company, generally suited to larger ventures or situations involving many shareholders.
• Sucursal (branch) — a branch of an existing foreign company, not a separate legal entity, which can be useful for certain established businesses.
• Sole trader (autónomo) — possible for individuals, but it places personal liability on the founder and is rarely the right fit for outside investors.

The S.L. is the most common answer to this question, but the right choice depends on ownership structure, investment plans and liability considerations.

What are the capital requirements?

For an S.L., the minimum share capital under Spanish law is set at a relatively low level, and it can be paid in cash or in kind. Founders should confirm the current figure and the rules on payment timing, as well as any regional or sector-specific conditions, with a local adviser. Capital requirements for an S.A. are higher. Regardless of the legal minimum, practical questions matter too: banks and counterparties often look at whether the company is adequately capitalised for its intended activity.

Can a foreigner own 100% of a Basque company?

In most sectors, yes. Foreign investment in Spain is generally open, and a foreign individual or company can usually hold the entire share capital of a Spanish company. There are, however, notification or authorisation requirements for certain regulated sectors and for some categories of foreign investment. Founders should check whether their specific activity falls under any of these rules before incorporation.

What documents will I need?

Although each case differs, a typical registration file includes:

• Proof of identity of the founders (passport or equivalent) and, where relevant, corporate documents for a company founder.
• A foreign tax identification number (NIE) for the individuals involved.
• A certificate confirming the company name is available (the denominación social).
• Evidence of the registered office address in the Basque Country.
• Bank documentation showing the deposit of share capital.
• Draft articles of association and the incorporation deed.
• Where applicable, a power of attorney for a representative acting on the founder's behalf.

Foreign documents often need to be legalised or apostilled and translated into Spanish. Document requirements are a frequent source of delay, so preparing them early is worthwhile.

What does the incorporation process look like?

The sequence typically runs as follows:

1. Name reservation — secure the company name.
2. Bank account and capital deposit — open a temporary account and deposit the share capital.
3. Public deed — sign the incorporation deed before a Spanish notary.
4. Registration — file the deed with the Mercantile Registry.
5. Tax and social security registration — obtain the company tax number and register with the relevant authorities.
6. Licences and permits — check whether the activity requires municipal or sector-specific authorisations.

Timelines vary considerably depending on document readiness, notary and registry availability, and the complexity of the activity. Founders should build in buffer time rather than plan around a best case.

How does taxation work in the Basque Country?

The Basque Country has its own corporate tax regime, administered by the provincial treasuries, with rates and reliefs that can differ from the rest of Spain. There are also regional incentives for certain activities, investment and innovation. Because the regime is distinctive and subject to change, founders should obtain current, case-specific tax advice rather than relying on general descriptions. VAT and indirect tax rules also have regional administration features that are worth understanding at the planning stage.

What ongoing obligations should I expect?

Registration is only the beginning. A Basque company will typically have to:

• Keep proper accounting records and file annual accounts.
• Submit periodic tax returns and pay corporate tax.
• Handle payroll and social security if it employs staff.
• Maintain statutory registers and hold required shareholder and board meetings.
• Keep the Mercantile Registry updated on changes to directors, capital or registered office.

Non-resident directors and shareholders should also consider their own personal tax and reporting positions, which may not be limited to Spain.

Is the Basque Country different from Madrid or Barcelona?

The main practical differences are the regional tax regime, the local support ecosystem and the industrial character of the area. The fundamentals of Spanish company law, the notary and registry process, and many compliance obligations are shared. Founders should not assume that advice written for Madrid applies unchanged to Bilbao, Donostia-San Sebastián or Vitoria-Gasteiz.

Final thoughts

Registering a company in the Basque Country is a structured process, but it rewards preparation. The most common mistakes are underestimating document requirements, choosing a legal form without advice and treating tax planning as an afterthought. Foreign founders should engage a local lawyer, an accountant and, where appropriate, a business adviser early.
