International investors and entrepreneurs setting up in Spain face a fundamental early decision: buy a pre-formed shelf company that is ready to trade within 24 hours, or incorporate a new company from scratch with a custom name and bespoke articles of association over 7 to 20 business days. This guide compares both routes in detail — legal framework, timelines, costs, registry privacy, and the impact of the Ley Crea y Crece reform — so you can make the right choice for your situation.
The decision is not simply about speed. It touches on corporate governance, registry privacy, tax configuration, credibility with banks and counterparties, and how the company is perceived during its first months of operation. Both routes are entirely legal, regulated, and widely used in Spanish corporate practice. The question is which one fits your circumstances.
Two routes to the same destination
In Spain, the most common legal form for small and medium-sized enterprises is the Sociedad de Responsabilidad Limitada (SL), equivalent to a limited liability company (LLC) in common-law jurisdictions or a GmbH in Germany. The SL accounts for more than 95% of new company formations in Spain and is the standard vehicle for both domestic businesses and foreign investment.
Both routes — buying a shelf company and incorporating from scratch — result in a fully operational SL (or SA, if needed) with a definitive tax identification number (CIF/NIF), registration at the Mercantile Registry (Registro Mercantil), and the ability to invoice, contract, hire employees, and trade.
The differences lie in how you get there.
What is a shelf company?
A shelf company — known in Spanish as a sociedad preconstituida or sociedad express — is a limited company that has been legally incorporated, registered with the Mercantile Registry, and assigned a definitive CIF, but has conducted no business activity since formation. It was created specifically for subsequent sale.
Every shelf company carries a certificate of inactivity confirming zero trading since incorporation, certificates from the AEAT (Spanish tax authority) and Social Security confirming no outstanding liabilities, and annual accounts filed at nil. It is not a company with an unknown past: it is a clean corporate vehicle, verified and documented, waiting for a buyer.
The transfer is formalised by public deed before a notary under the Ley de Sociedades de Capital (Royal Decree 1/2010), the same law that governs any share transfer in a Spanish company. The notary verifies the identity of all parties and ensures compliance with anti-money laundering obligations under Law 10/2010.
What does incorporation from scratch involve?
Forming a new SL in Spain follows a multi-step administrative procedure:
-
Name certificate (Certificación Negativa de Denominación Social). You request a certificate from the Central Mercantile Registry confirming that your chosen company name is not already in use. This takes 2 to 5 business days.
-
Bank deposit of share capital. You open a bank account in the name of the company being formed and deposit the share capital. Under current law, the minimum is technically one euro, though in practice most founders deposit at least three thousand euros.
-
Drafting of articles of association. You prepare the company’s bylaws, defining the corporate purpose, management structure, share transfer restrictions, and governance rules.
-
Notarial deed of incorporation. Founders sign the deed of incorporation before a notary, presenting the name certificate, proof of capital deposit, and articles of association.
-
Tax registration. You apply for a provisional NIF (tax identification number) using Form 036 filed with the AEAT.
-
Mercantile Registry inscription. You file the deed with the provincial Mercantile Registry. Registration takes 5 to 15 business days depending on the registry’s workload. Upon inscription, the NIF becomes definitive.
The entire process, from name application to definitive NIF, takes 7 to 20 business days under standard procedure. The CIRCE online fast-track system (Centro de Informacion y Red de Creacion de Empresas) can compress this to 5 to 7 days for standardised formations, but it imposes limitations on the articles of association and is not available for all configurations.
Our company formation service manages the full process with an average completion time of 10 business days.
Head-to-head comparison
The following table summarises the key differences between buying a shelf company and incorporating a new one. All figures relate to a standard SL (Sociedad de Responsabilidad Limitada) with three thousand euros of share capital.
| Factor | Shelf Company | New Incorporation |
|---|---|---|
| Time to operational company | 24 to 48 hours | 7 to 20 business days |
| Definitive CIF from day one | Yes | No (provisional until registry inscription) |
| Share capital | Already paid up and in the company | Must be deposited by founders |
| Company name | Pre-assigned (can trade under any name) | Chosen by founders (subject to availability) |
| Business purpose (CNAE) | Changed at purchase, no extra cost | Defined at incorporation |
| Articles of association | Standard (can be amended later) | Bespoke, drafted to order |
| Cost (SL, €3,000 capital) | From €1,395 + VAT (capital included) | €1,500 to €3,000 (capital + notary + registry + advisory) |
| Registry privacy | New shareholders not registered publicly | Founding shareholders appear in the deed |
| Signing without travel | Yes, by power of attorney | Possible but less common |
| Shareholders’ agreement | Can be executed simultaneously | Can be executed simultaneously |
| Annual accounts | Filed (at nil) since formation | No history |
| Company age / track record | 1 to 10 years available | Zero |
| Suitable for public tenders | Immediately (registered entity) | Only after registry inscription |
| Anti-money laundering compliance | Full (beneficial ownership declared) | Full (beneficial ownership declared) |
The legal framework: Ley de Sociedades de Capital and Ley Crea y Crece
Both routes are governed by the Ley de Sociedades de Capital (LSC), consolidated in Royal Decree 1/2010, which is Spain’s primary corporate law statute. The LSC regulates the formation of SLs and SAs (articles 21 to 32), the transfer of shares (articles 106 to 112 for SLs), and the ongoing governance obligations of all Spanish companies.
Ley Crea y Crece (Law 18/2022)
The Ley de Creacion y Crecimiento de Empresas, commonly known as Ley Crea y Crece, entered into force in October 2022 and introduced two changes that directly affect this comparison:
Minimum capital reduced to one euro. Before this law, forming an SL required a minimum of three thousand euros of share capital. The reform eliminated this minimum, allowing incorporation with just one euro. However, the law imposes a reinforced legal reserve obligation: for the first two financial years in which the company earns a profit, it must allocate 20% of profits to a legal reserve until total equity reaches three thousand euros. During this period, the company also faces restrictions on profit distribution.
Digital formation via CIRCE. The law expanded the CIRCE online platform to allow faster formation using standardised articles of association, reducing timelines to approximately 5 to 7 business days for straightforward cases.
How this affects shelf companies
The Ley Crea y Crece made incorporation cheaper in theory (one euro instead of three thousand), but it did not make it faster. The registry bottleneck remains: Mercantile Registries still take 5 to 15 business days to process inscriptions. For buyers who need a company operational this week, the reform changed nothing.
Furthermore, the reinforced legal reserve obligation means that a company incorporated with one euro of capital will not be able to distribute dividends freely until equity reaches three thousand euros. By contrast, a shelf company with three thousand euros of capital already deposited avoids this restriction entirely.
In practice, we advise founders incorporating from scratch to still capitalise at three thousand euros or more. A company with one euro of capital can face credibility problems with banks (some refuse to open accounts for companies capitalised at one euro), suppliers (who may question the company’s solvency), and institutional counterparties.
Cost breakdown in detail
Understanding the true cost of each option requires looking beyond the headline price.
Incorporating a new SL
| Item | Amount |
|---|---|
| Name certificate (Central Registry) | €15 to €20 |
| Notary fees (deed of incorporation) | €300 to €600 |
| Mercantile Registry inscription | €100 to €250 |
| Advisory / law firm fees | €400 to €1,500 |
| Share capital deposit | €3,000 (stays in the company) |
| Total out-of-pocket | €3,815 to €5,370 |
Of this total, three thousand euros remain in the company as equity. The non-recoverable cost (fees and charges) is typically eight hundred to two thousand three hundred euros.
Buying a shelf company (SL, €3,000 capital)
| Item | Amount |
|---|---|
| Shelf company purchase price | From €1,395 + VAT |
| Notary fees (share transfer deed) | Included in price |
| Mercantile Registry filings | Included in price |
| Beneficial ownership declaration | Included in price |
| Share capital | Already in the company |
| Total out-of-pocket | From €1,688 (€1,395 + 21% VAT) |
The share capital is already in the company. The purchase price covers the company itself, notary, registry filings, and documentation. There are no separate notary or registry charges.
Net comparison
The apparent cost of buying a shelf company is lower because you are not making a separate capital deposit — the three thousand euros is already inside the company when you buy it. If you factor out the share capital from both calculations (since it remains as company equity in both cases), the non-recoverable cost is comparable: approximately eight hundred to two thousand three hundred euros for incorporation, versus approximately one thousand seven hundred euros for a shelf company purchase.
The real economic difference is not in euros but in days. Every day without an operational company is a day without invoicing. For a company expecting to invoice ten thousand euros per month, a two-week delay represents five thousand euros of deferred revenue. That opportunity cost dwarfs any difference in formation fees.
Registry privacy: a practical advantage
One of the most frequently cited advantages of buying a shelf company is registry privacy.
When you incorporate a new company, the deed of incorporation — which identifies the founding shareholders, their nationalities, addresses, and shareholdings — is filed with the Mercantile Registry and becomes publicly accessible. Anyone can request a nota simple (registry extract) and see who the founders are.
When you buy a shelf company with two or more shareholders, the share transfer is formalised by notarial deed but is not registered with the Mercantile Registry. The registry continues to show the original founding shareholders. The new acquirers do not appear in the public record.
This is not a loophole or an opacity mechanism. It is a direct consequence of how the LSC treats share transfers in limited companies. The notary identifies all parties and verifies compliance with anti-money laundering rules. The beneficial ownership declaration is filed with both the Mercantile Registry and the AEAT. The privacy applies at the registry level only — the tax authority and relevant compliance bodies know the real ownership.
For whom does this matter? International investors who prefer to keep their identity out of publicly searchable commercial databases. Entrepreneurs who are still employed and do not want their current employer to discover their new venture through a simple registry search. High-net-worth individuals structuring investments through corporate vehicles.
If registry privacy is not a concern, this factor alone does not justify choosing a shelf company over incorporation.
Process comparison: step by step
Buying a shelf company
| Step | Timeline |
|---|---|
| Select company (type, capital, province) | Same day |
| Document preparation (transfer deed, director changes, CNAE) | 24 to 48 hours |
| Notarial signing (in person or by power of attorney) | 1 hour (in person) |
| Company operational (can invoice, contract, trade) | Day of signing |
| Registry filing of changes (runs in background) | 5 to 15 business days |
The company is operational from the moment of signing. Registry filing of the new director and registered office runs in the background and does not prevent trading.
Incorporating from scratch
| Step | Timeline |
|---|---|
| Name certificate application | 2 to 5 business days |
| Bank account opening and capital deposit | 1 to 3 business days |
| Articles of association drafting | 2 to 5 business days (parallel) |
| Notarial signing of incorporation deed | 1 day (once all documents ready) |
| Application for provisional NIF | 1 to 2 business days |
| Mercantile Registry inscription | 5 to 15 business days |
| Definitive NIF | Upon inscription |
The company cannot invoice or trade with a definitive CIF until the Mercantile Registry inscription is complete. The provisional NIF allows some preliminary steps (opening accounts, signing contracts) but is not accepted by many banks, clients, or institutional counterparties.
For non-residents: additional steps
Non-resident founders face additional requirements that extend the timeline:
- NIE (Numero de Identificacion de Extranjero). Required for any foreign individual who will be a shareholder or director. Processing takes 1 to 4 weeks depending on the consulate or police office.
- Document apostille or legalisation. Identity documents and corporate certificates from outside Spain must be apostilled (Hague Convention countries) or legalised (others) and, in some cases, officially translated.
- Travel. Standard incorporation typically requires the founder to be present before the notary. Shelf companies can be purchased by power of attorney without travelling to Spain.
For a non-resident incorporating from scratch, the realistic total timeline is 3 to 6 weeks. A shelf company purchase, even by power of attorney, can be completed in 48 to 72 hours.
When to buy a shelf company
The shelf company is the right choice when one or more of these conditions apply:
- Time is critical. You have a contract to sign, an invoice to raise, a real estate transaction to close, or a public tender deadline within the next two weeks.
- You are a non-resident and want to avoid travel. The full process — selection, documentation, signing by power of attorney — can be completed without setting foot in Spain.
- Registry privacy matters. You prefer that your name does not appear in the publicly searchable Mercantile Registry.
- You need an established entity. Certain tenders, franchise agreements, and institutional relationships require a company with a registration history. Shelf companies aged 1 to 10 years satisfy this requirement.
- You want a definitive CIF from day one. No provisional NIF, no waiting for registry inscription, no bank refusing to open an account because the NIF is provisional.
- You need higher capital. For regulated sectors, franchises, or projects requiring demonstrated financial substance, shelf companies with ten thousand to two hundred and forty thousand euros of capital are available off the shelf.

When to incorporate from scratch
Bespoke incorporation is the right choice when:
- You need a specific company name. The company name matters to you and you want to choose it. Shelf companies come with a pre-assigned denomination that is not changed in the standard process.
- You want tailored articles of association. You need bespoke governance rules — specific majority requirements, complex share classes, drag-along and tag-along provisions, or a board of directors rather than a sole director. Standard shelf company articles can be amended later, but if governance design is critical from day one, bespoke formation is cleaner.
- Time is not a constraint. If you are in a planning phase with no immediate operational need, the 7 to 15 business day timeline is perfectly acceptable.
- You are incorporating with minimal capital. Under the Ley Crea y Crece, you can form an SL with as little as one euro. This option is not available through a shelf company purchase (shelf companies carry a minimum of three thousand euros of capital).
- You are forming a complex structure. Holding companies, joint ventures, or multi-jurisdictional structures with bespoke articles and shareholders’ agreements are better served by custom formation from the outset.

Frequently overlooked considerations
Company age and bank relationships
Some banks and financial institutions look more favourably on companies with a longer registration history. A shelf company formed three years ago has a Mercantile Registry entry dating back three years, which can ease the account-opening process, particularly for non-residents. This is an unofficial but practical consideration that matters more than most advisors acknowledge.
CNAE code and tax regime
Both routes require correct configuration of the company’s economic activity code (CNAE — Clasificacion Nacional de Actividades Economicas) and tax regime (VAT, withholding taxes, Corporate Income Tax). In a shelf company purchase, the CNAE is changed as part of the transfer at no additional cost. In a new incorporation, the CNAE is defined in the deed of incorporation. Getting this right from the start avoids complications with quarterly filings.
Director liability from day one
Whoever is appointed as director (administrador) — whether through a shelf company purchase or a new incorporation — assumes the duties and liabilities established in articles 225 to 232 of the LSC from the moment of appointment. These include the duty of diligence, the duty of loyalty, and potential personal liability for corporate debts in specific circumstances (notably under article 367 LSC when a dissolution cause exists and the director fails to act). This obligation is identical regardless of how the company was formed.
Beneficial ownership register
Since February 2025, Royal Decree 609/2023 requires all Spanish companies to file a beneficial ownership declaration with the Mercantile Registry. Both routes — purchase and formation — result in the same compliance obligation. The AEAT also requires beneficial ownership information in the census declaration (Form 036). There is no beneficial ownership advantage to either route.
Decision framework
Use this framework to determine the right route for your situation:
Choose a shelf company if: You need the company operational within 48 hours, or you are a non-resident who wants to avoid travel, or registry privacy is important to you, or you need a company with a history for tenders or institutional requirements. The premium you pay (if any) is for time saved and convenience.
Choose bespoke incorporation if: You have 2 to 4 weeks before the company needs to be operational, you want to choose the company name, you need complex or customised articles of association from day one, or you are forming a holding or multi-entity structure where governance design is a priority.
Either route works equally well if: You are forming a standard SL for a domestic business, the timeline is flexible, and you have no strong preference on name or registry privacy. In this case, compare the total out-of-pocket cost and choose whichever is more convenient.
In all cases, the company needs professional management from the moment it starts trading: accounting, tax filings, annual accounts, corporate secretarial compliance, and ongoing advisory. At BMC, both routes lead to the same ongoing relationship. Whether you buy one of our shelf companies or we form your company from scratch, our tax and legal team manages the company from day one with a single point of contact who understands the full picture.
