Ready Made Company Spain: Buying a Shelf SL, the Sociedad Preconstituida

What a Ready-Made Company in Spain Is

A ready-made company, also called a shelf company, an off the shelf company or simply a ready company, is a company registered in advance, kept without business and sold to someone who needs one that already exists. In Spain it is nearly always an SL, the private limited company, and Spanish law has its own name for it: a sociedad preconstituida, which the anti-money-laundering regulation defines as a company formed without real economic activity in order to be transferred to third parties later (RD 304/2014 art. 19). The tax census recognises the category as well. When the promoter applies for the company’s NIF, it declares on modelo 036 that the SL is being formed for sale and will carry on no activity until it is sold (RGAT art. 4; Agencia Tributaria). The phrase sociedad instrumental, sometimes used loosely, means something different in Spain: the tax agency’s annual control plans apply it to companies that members misuse to pay personal expenses or to hold assets for private use. Buying a sociedad preconstituida creates nothing new. It changes who owns the participaciones, which are the SL’s shares, and who runs the company.

What Stays with the SL and What the Buyer Changes

Item	After the purchase
Legal personality and date of registration	Unchanged; the SL has been a legal person since it was registered (LSC art. 33)
NIF, beginning with B	Unchanged; it would change only with the legal form or nationality (RGAT art. 22)
Capital	Already paid in full, as every SL participation is paid when the founding deed is signed (art. 78)
Estatutos	Unchanged until amended; they may restrict transfers, and may even bar them for up to five years after formation (arts. 107 and 108), so they are read before anything is signed
Members	The buyer, entered in the company’s own register of members, which decides whom the company treats as a member (art. 104)
Administrador	A new one appointed by the members, effective on acceptance and filed for registration within ten days (arts. 214 and 215)
Registered office within Spain	Moved by the administrators, unless the estatutos expressly keep that power for the members (art. 285)
Name and business object	Changed by the members in a public deed that is registered; a new name needs a fresh certificate from the Registro Mercantil Central (art. 290; RRM art. 413)
Intra-EU VAT number	None until the buyer applies, as explained below
Bank account	Stays with the company if one exists; the bank decides whether to keep it

How Participaciones in a Spanish SL Change Hands

A sale of participaciones has to be made in a public document (art. 106), which in practice means a deed of sale, the escritura de compraventa, signed before a Spanish notary. Unless the estatutos provide otherwise, a sale to an outsider follows the statutory route: the seller tells the administrators in writing who the buyer is and on what terms, the general meeting decides whether to consent, and members attending that meeting have a right of first refusal (art. 107). In a single-member shelf company the seller exercises the powers of the general meeting (art. 15), so that consent is the seller’s own decision. A sale that disregards the law or the estatutos has no effect against the company (art. 112).

At the notary every party proves its Spanish tax number, which for a foreign individual means the NIE, and before signing the notary checks the list of revoked NIFs and must refuse to authorise a deed for a company whose number has been revoked (Ley del Notariado art. 23). Obliged entities, notaries and banks among them, must also apply enhanced due diligence to transfers of participaciones in a sociedad preconstituida (RD 304/2014 art. 19), so the buyer’s identity, the beneficial owners and the origin of the purchase money are documented first. A buyer who cannot attend signs through an attorney holding a power for that act. A Spanish notary can authorise a power for a specific act by videoconference (Ley del Notariado art. 17 ter), and a power signed before a notary abroad is used with an apostille and a sworn translation.

The sale itself is exempt from VAT and from transfer tax under art. 338 of the Securities Markets Law. The exception is an anti-avoidance rule: taking control of a company whose assets are at least half Spanish real estate not used in a business is taxed as a transfer of that property, which a never-traded SL does not own. A non-resident buyer who reaches 10% or more of the capital declares the investment to the Registro de Inversiones after the purchase; when the buyer gave the notary the required data, the notary passes it on and the buyer need not file (RD 571/2023 arts. 4 and 5).

Filings After the Purchase and Their Deadlines

Filing	Rule	Source
Change of sole member, or the SL becoming single-member	Recorded in a public deed and registered in the Registro Mercantil; if a company that has become single-member is not registered as such within six months, the sole member answers personally for its debts of that period	LSC arts. 13 and 14; RRM art. 203
New administrador	Filed for registration within ten days of accepting the post	LSC art. 215
New name, object or other change to the estatutos	Public deed, then registration	LSC art. 290
Tax census update	The buyer files modelo 036 within one month of the sale, changing the domicile, representatives and members and declaring the start of activity, corporate tax and VAT, with the registered deeds	RGAT art. 12; Agencia Tributaria
Start of activity	Business or preparatory acts within three months of that census update; otherwise the NIF may be revoked	RGAT art. 147
Beneficial owners	The Registro Central de Titularidades Reales takes them from the notarial deed of sale, the accounts deposit or a new declaration	RD 609/2023 art. 3

The transfer of participaciones is not itself entered on the company’s sheet at the Registro Mercantil, which records the constitution, changes to the estatutos, administrators and powers, among other acts (RRM art. 94). Ownership is shown by the notarial deed and the register of members, which is why a change of sole member needs a filing of its own.

VAT Number and Tax Record of a Spanish Shelf SL

Buyers often look for a ready-made company with a VAT number, and in Spain the answer needs care. The company’s NIF also serves as its domestic VAT number, but the intra-EU number that VIES confirms comes only with entry in the Registro de Operadores Intracomunitarios, and an SL declared as formed for sale is kept out of that register until it is transferred (RGAT art. 4). A shelf SL declared this way therefore comes without a VIES-valid number. After the purchase the buyer asks for one on modelo 036, and the tax agency says that a request it has not resolved within three months may be taken as refused, so anyone who needs an EU company trading across borders soon should plan for that step.

The tax record still matters before signing. Every company subject to corporate tax files a return each year, even when there is nothing to report (LIS art. 124), and an SL deposits its accounts every year (art. 279). Three checks follow. Have the returns been filed? Are the deposits up to date, given that a company in default cannot register a new administrador (art. 282)? And is the NIF still valid, given that a revoked number stops notaries from authorising deeds for the company and banks from moving money on its accounts (General Tax Act, sixth additional provision)? Once it trades, the SL pays corporate tax and VAT like any other; the rates are on our page about company registration in Spain.

Bank Accounts and a Ready-Made Spanish SL

A Spanish SL may have been formed without a bank at all, because its founders can declare in the deed that they answer jointly for the cash contributions instead of producing a bank certificate (art. 62). A shelf SL may therefore hold no account. Where it does, the account belongs to the company and stays with it after the sale, but Spanish banks must repeat due diligence whenever a customer’s circumstances change (Ley 10/2010 art. 7) and the enhanced measures for transfers of a sociedad preconstituida apply, so the bank re-checks the new members, administrador and beneficial owners and may keep the account, ask for more information or close it. For a company without an account, the requirements banks publish include the registered deeds and powers, the NIF and the latest VAT or corporate tax return, or the modelo 036 for a company that has not filed yet. Our page on bank accounts for Spanish companies covers what banks publish, and shelf companies with bank accounts explains how pre-banked companies work in general.

When a Shelf SL Brings Nothing Over a New One

Spain registers new companies quickly on paper. Through the electronic CIRCE route the law gives the registry six business hours to register an SL with standard statutes, and the capital can be as low as one euro, so a buyer who merely needs a company soon may gain little. What a sociedad preconstituida really adds is existence: it is already a legal person with a settled NIF and registration date, so nobody has to sign for a company in formation and carry the personal liability that comes with it (art. 36). It brings no trading history, no customers, no credit record, no licence and no intra-EU VAT number, and it does not spare the buyer the NIE, the notary, the enhanced checks or the census filings. A founder who wants estatutos and a share structure designed from scratch should form a new SL, as explained on our company formation in Spain page. Buyers who want age for its own sake should first read our note on aged shelf companies, because an older date on a never-traded company is not a trading record.

Our Part When You Buy a Spanish SL

We supply ready-made Spanish SLs and also form new ones. For a purchase we prepare the deed of sale and the members’ decisions with the notary, and the registry filings described above, help prepare the bank application, and, where we have a working contact at a suitable bank, make an introduction while the bank alone decides. The Spain overview gives background on the country, and buyers comparing several countries can start from off the shelf companies.

Frequently Asked Questions about Ready-Made Companies in Spain

What is a sociedad preconstituida?

It is the Spanish term for a shelf company: an SL formed without real economic activity so that it can be sold later, as the anti-money-laundering regulation defines it. The promoter tells the tax agency at the outset that the company is being formed for sale. The buyer takes over its participaciones and appoints a new administrador, and the company keeps its original registration date and NIF.

Can I buy a shelf company in Spain from abroad?

Yes. Neither the members nor the administrador of an SL need to live in Spain or hold Spanish nationality. Each foreign individual does need a NIE, the number the notary records as the party’s Spanish tax number, and it can be requested through a Spanish consular office. A buyer who cannot attend the notary signs through an attorney, using a power granted by videoconference before a Spanish notary or before a notary abroad with an apostille.

Does a Spanish shelf company come with a VAT number?

It has a NIF, which also works as its domestic VAT number, but not an intra-EU VAT number. A company declared as formed for sale stays outside the Registro de Operadores Intracomunitarios until it is sold, so it does not appear in VIES. The buyer applies for inclusion on modelo 036 after the purchase, and the tax agency may treat a request left unresolved for three months as refused.

Is there tax on buying the participaciones of a Spanish SL?

Normally not. Under art. 338 of the Securities Markets Law the transfer is exempt from both VAT and transfer tax. The exception targets property: acquiring control of a company whose assets are mostly Spanish real estate not used in a business is taxed as a transfer of that real estate. A never-traded shelf SL holds no property, so the exemption applies to its sale.

Is the purchase recorded in the Registro Mercantil?

Not the sale itself. A transfer of participaciones is documented by notarial deed and entered in the company’s register of members. What the Registro Mercantil records is a change of sole member, the new administrador and any change to the name, object or other estatutos. The Registro Central de Titularidades Reales, for its part, takes the beneficial owners’ details from the notarial deed of sale.

Can I change the name of a ready-made SL?

Yes, but it is a change to the estatutos, so the members decide it. The company first obtains a certificate from the Registro Mercantil Central that the new name is not registered, then the decision is put into a public deed and registered with the Registro Mercantil of its domicile. The NIF stays the same; the company then updates its tax census entry with the new name.
