Company Formation in Spain for Foreigners: Setting Up an SL

For a US, UK or other non-EU founder, setting up a company in Spain through a Sociedad de Responsabilidad Limitada (SL) is one possible operating or investment structure—not a default answer. Before incorporation, compare a subsidiary, branch and personal activity; map cross-border funding, profit extraction, management and ownership; then complete the Spanish identity, beneficial-owner, notarial, registry, tax and social-security work required for the chosen model.

Key Takeaways

• An SL is a limited-liability capital company governed principally by Spain’s Companies Act.
• As checked against the consolidated Companies Act on 21 August 2026, the legal minimum capital is €1, but special reserve and shareholder-liability rules apply while capital remains below €3,000.
• The governance model, corporate purpose and transfer rules should be designed before the deed is signed.
• Foreign identity, tax-number, beneficial-owner, translation and legalisation requirements depend on who the founders and directors are.
• Incorporation and operational readiness are different milestones; tax, banking, licences and social security may continue after registry filing.
• Corporate-tax and social-security treatment depend on the facts and the law for the relevant period.
• Coordinate Spanish structure and management with home-country entity classification, controlled-company, reporting, succession and exit advice.

Is an SL Right When Setting Up a Company in Spain?

The SL is Spain’s private limited-liability company. Under the Companies Act (Real Decreto Legislativo 1/2010), its capital is divided into participations and shareholders generally do not answer personally for company debts merely because they hold those participations.

Shareholder exposure is distinct from director liability. A shareholder may assume personal guarantees, have to repay an unlawful distribution where the statutory conditions are met, or face the special liability described below where SL capital remains below €3,000. These are not the same as liability merely for holding participations.

Directors have separate statutory duties. Misconduct, breach of those duties and failures to take required action in insolvency or when dissolution grounds arise can create personal liability under the applicable rules. A person who is both shareholder and director must assess each role separately; the Companies Act addresses shareholder rules in Articles 4 and 278 and director duties and liability in Articles 225, 236 and 367.

An SL often suits owner-managed businesses, subsidiaries and joint ventures, but founders should compare it with:

• A branch of a foreign company.
• A Spanish public limited company (Sociedad Anónima or SA).
• An individual business activity.
• Another contractual or corporate structure.

The decision should consider liability, governance, investment plans, tax, repatriation of profits, regulation, hiring and the planned exit—not simply the lowest incorporation cost.

A US LLC, UK limited company, trust, partnership or family investment vehicle may not be classified or taxed in Spain as its owners expect. Before placing that vehicle above or beside an SL, advisers in both countries should compare legal ownership, tax classification, treaty access, beneficial ownership, management location, distributions and exit consequences.

Can a foreign founder own or direct a Spanish SL?

Foreign individuals and companies can participate in Spanish company formation, but the exact pre-incorporation documents vary. Counsel and the notary should confirm the requirements for each shareholder, beneficial owner, director and representative.

The file may require:

• Spanish identification or tax numbers for relevant individuals and entities.
• Passports and current address evidence.
• Proof of the foreign company’s existence, governance and authorised signatory.
• Beneficial-ownership information.
• Corporate resolutions approving the investment.
• Apostille or legalisation of foreign public documents, where applicable.
• Sworn or otherwise accepted Spanish translations.
• A power of attorney if someone will sign in Spain for a founder.

Foreign-investment reporting is not limited to sensitive sectors. Under Articles 3–5 of Royal Decree 571/2023, a non-resident who subscribes for or acquires shares or participations and holds or reaches at least 10% of a Spanish company’s capital or voting rights generally triggers reporting to the Investment Registry. This includes subscribing on incorporation, not just buying an existing company. Confirm the applicable declaration route and who will make it; reporting is generally after the investment, with additional rules for specified cases.

Prior investment screening and authorisation are a separate question under Article 7 bis of Law 19/2003 and Royal Decree 571/2023. Assess the investor, beneficial ownership and structure, sector and transaction, including applicable exemptions and transitional rules, before committing. An ordinary reporting obligation is not itself a requirement for prior approval.

Beneficial-ownership identification and updates must also be coordinated with the Central Register of Beneficial Ownership established by Royal Decree 609/2023. Its framework centralises information from sources including the Commercial Registry and notarial records; confirm the applicable reporting route rather than assuming every company must make the same direct filing.

How much share capital does a Spanish SL need?

As checked against the consolidated Companies Act on 21 August 2026, an SL may be formed with €1 of capital. That figure is a legal floor, not a recommendation for every business; it must be rechecked before incorporation.

Until capital reaches €3,000, special protections apply. The Act requires at least 20% of annual profit to be allocated to the legal reserve until capital plus that reserve reaches €3,000. If the company is liquidated and its assets are insufficient to meet its obligations, shareholders can be jointly liable for the difference between €3,000 and subscribed capital.

Founders should therefore set capital by reference to the business plan, early expenses, bank expectations, licences, creditor confidence and funding structure. Share capital is not the same as a professional or registration fee, and additional funding may be provided through properly documented mechanisms.

Step-by-step: how to set up an SL in Spain

1. Choose the structure and founders

Decide who will own the participations, percentages, funding, governance rights and transfer restrictions. For joint ventures, consider a shareholders’ agreement alongside the bylaws.

2. Clear the company name

A negative name certificate is normally obtained from the Central Commercial Registry. Confirm its current application channel, reservation period and evidence requirements when the file begins.

3. Prepare foreign-founder documents

Obtain the required tax identifiers, certificates, resolutions, beneficial-owner evidence, translations and apostilles or legalisations. This stage often determines the real timetable.

4. Decide capital and funding

Set the subscribed capital and how contributions will be made and evidenced. Cash and non-cash contributions have different documentation and responsibility issues. Do not use €1 merely because the statute allows it.

Document whether later funds are capital, shareholder loans or third-party debt, and prepare the source-of-funds trail before money enters Spain. Funding in dollars, sterling or another currency also requires a euro amount, conversion record and timing plan. The bank’s acceptance of a transfer does not determine its corporate or tax treatment.

5. Draft the bylaws and governance

The bylaws should cover the corporate name, purpose, registered office, capital, participations, financial year and administration system. The deed also identifies initial shareholders and directors.

Governance choices may include a sole director, several joint or joint-and-several directors, or a board. The best model depends on control, signing authority, investor protections and where management will actually occur.

6. Sign the public deed

The founders or properly authorised representatives execute the incorporation deed before a Spanish notary. The notary will require the corporate, identity, ownership and capital documentation applicable to the file.

7. Complete tax and Commercial Registry steps

The company needs a Spanish tax identification number and relevant census registrations. The deed is filed with the competent Commercial Registry. The sequence between provisional tax identification, filing, correction of defects and definitive registrations should be managed for the actual case.

8. Make the company operational

Depending on the business, this may include:

• Bank-account activation and signatory controls.
• VAT and other tax registrations.
• Activity, premises or sector licences.
• Employment and social-security registrations.
• Data-protection and consumer documentation.
• Accounting books, invoicing and annual-compliance systems.
• Contracts with founders, directors, staff, customers and suppliers.

A registered company is not automatically authorised to conduct every regulated activity.

How long does Spanish company formation take?

There is no reliable universal timeline. Name clearance, foreign tax identifiers, bank compliance, document legalisation, notarial availability, registry review and correction of defects can each affect completion.

A remote incorporation can be possible through a suitable power, but remote signing does not remove bank, identity or beneficial-owner checks. See the guide to powers of attorney in Spain for foreigners before choosing that route.

Set the project timetable only after counsel has reviewed the founders, documents, funding and regulated activity. Separate the target date for legal incorporation from the date the business must employ staff, invoice, open premises or obtain a licence.

Tax and social security after incorporation

A Spanish SL falls within the framework of the Corporate Income Tax Law (Ley 27/2014). Rates, incentives and conditions can change by period and company profile, so this guide does not state a universal rate. New-company or startup treatment should be confirmed for the tax year and activity.

The Spanish analysis should be coordinated with the founder’s home-country rules for entity classification, controlled foreign companies, dividends, interest, capital gains and information reporting. For owner-managed groups, where strategic decisions are actually made can matter alongside the registered office. Incorporation in Spain should not be used to assume that every management, permanent-establishment or treaty question has been resolved.

Directors and working shareholders also need a classification analysis under the General Social Security Law. Registration is not determined by the title “director” alone: ownership, effective control, paid functions and working relationship matter.

Companies that may qualify as emerging companies should review the conditions and measures in Law 28/2022 on the startup ecosystem. Incorporating a new SL does not automatically confer certified startup status or every benefit in that law.

Ongoing obligations commonly include bookkeeping, tax returns, approval and filing of annual accounts, corporate records, beneficial-owner updates and employment compliance where applicable.

Decisions to make before the notary appointment

Common mistakes by foreign founders

• Choosing an SL before comparing a branch or other structure.
• Treating €1 as adequate operating funding.
• Ordering foreign documents before confirming wording, validity and legalisation.
• Using generic bylaws that do not match investor rights or business plans.
• Appointing directors without analysing authority, liability, tax residence or social security.
• Promising a launch date before bank, notary and registry checks are mapped.
• Assuming registration includes sector and premises licences.
• Forgetting annual accounts, books, tax and beneficial-owner updates after formation.

Frequently Asked Questions

What is the minimum capital for an SL in Spain?

As checked on 21 August 2026, the statutory minimum is €1. Special legal-reserve and shareholder-liability rules apply while capital remains below €3,000. Recheck the consolidated Act before incorporation; the commercially appropriate amount may be higher.

Can an SL have one shareholder?

The Companies Act recognises single-member capital companies. Sole-member status carries disclosure and recordkeeping rules that should be reflected in the incorporation and ongoing corporate records.

Do foreign founders have to travel to Spain?

Not necessarily. A representative may be able to sign under an appropriate power of attorney. However, identity, bank, tax, beneficial-owner and document requirements still apply, and some steps may require additional cooperation from the founder.

When can the company start trading?

That depends on more than the deed. Registry and tax steps, banking, invoicing readiness, licences, staffing and sector regulation may all affect the operational date.

Does every new SL receive startup tax benefits?

No. Corporate-tax rules and any startup measures have statutory conditions. Eligibility must be tested against the company, activity, ownership and relevant tax period.
