SL Company Registration — Handled by Our Barcelona Team
A step-by-step look at forming a Sociedad Limitada as a foreign entrepreneur — what you need before you start, how the process works, and what it actually costs.
We manage your SL incorporation end-to-end: reserving the company name, coordinating the notary appointment, filing with the Commercial Registry, and completing tax registration — so you don't have to navigate Spanish institutions yourself.
Why the Sociedad Limitada Is the Standard Choice
The Sociedad Limitada, or SL, is Spain's equivalent of a private limited company and the vehicle most foreign entrepreneurs use when they're doing more than freelancing. Unlike registering as an autónomo (sole trader), where your personal assets sit exposed to business debts and liabilities, an SL creates a separate legal entity. Your exposure is generally limited to what you've put into the company's share capital.
That distinction matters more than it might seem at first. An autónomo setup is faster and cheaper to run day to day, but it makes sense mainly for solo consultants or freelancers with modest revenue and low risk. Once you're hiring staff, signing commercial contracts, taking on investors, or operating in a sector with real liability exposure — construction, hospitality, import/export — the SL structure is what banks, landlords, and business partners expect to see. It also tends to look more credible to Spanish tax authorities and to counterparties who are used to dealing with incorporated entities rather than individuals trading under their own name.
For founders coming from the US or UK, the SL is broadly comparable to an LLC or a UK Ltd, though the mechanics of formation, taxation, and ongoing compliance are distinctly Spanish and don't map cleanly onto either system.
What You Need Before You Start
NIE for Administrators and Shareholders
Every director and shareholder needs a Número de Identificación de Extranjero before they can sign incorporation documents or appear on the company registry. If you haven't obtained yours yet, see our guide on the NIE number — it's usually the first thing to sort out, since everything else depends on it.
A Certified Company Name
You'll need to reserve and certify a unique company name through the Registro Mercantil Central (Central Commercial Registry). They check your proposed name against existing companies and issue a certificate confirming it's available — this certificate is valid for a limited window, so timing your other steps around it matters.
Share Capital
Since the 2022 "Crea y Crece" law, the legal minimum share capital for an SL is just €1. In practice, most advisors still recommend incorporating with €3,000. Below that threshold, 20% of annual profits must be set aside into a legal reserve each year, and shareholders can carry personal liability for any shortfall if the company is liquidated before capital reaches €3,000. Starting with the full amount avoids that complication entirely.
A Spanish Bank Account
Share capital has to be deposited into a Spanish business account before the notary will issue the deed of incorporation. Opening one as a non-resident has its own hurdles — our business bank account guide walks through what banks typically ask for and how to prepare.
The Registration Process
1. Reserve and Certify the Company Name
Submit up to five name options to the Registro Mercantil Central. They'll certify the first available one, typically within a few business days.
2. Open the Bank Account and Deposit Capital
With the name certificate in hand, open a Spanish business bank account and deposit your share capital. The bank issues a certificate confirming the deposit, which the notary will need.
3. Draft and Sign the Deed of Incorporation
The escritura de constitución — the notarized deed — sets out the company bylaws, shareholder structure, and administrator appointments. Non-residents don't need to be physically present in Spain for this step; you can travel to sign in person or grant power of attorney to a representative who signs on your behalf.
4. File with the Commercial Registry
The notary submits the deed to the Registro Mercantil for the province where the company is domiciled. Once registered, the company legally exists and can begin operating.
5. Tax Registration
The final step is obtaining the company's NIF (tax ID) and filing the census declaration (declaración censal) with the Agencia Tributaria, which registers the company for the relevant tax obligations, including VAT/IVA registration if the business will be invoicing for goods or services. From here, ongoing bookkeeping and filings are usually handled through accounting and bookkeeping support rather than as one-off tasks.
Costs & Timeline
These figures are estimates based on typical cases — actual costs depend on share capital, notary chosen, and whether bylaws are standard or customized.
| Item | Typical Range | Notes |
|---|---|---|
| Notary, registry & advisor fees combined | Roughly €2,500–€4,000 | Varies by capital amount and complexity of bylaws |
| Minimum share capital | €1 legal minimum; €3,000 commonly recommended | Avoids the legal reserve requirement and liability exposure below €3,000 |
| Standard formation timeline | 2–4 weeks | Typical for non-resident or customized setups |
| Fast-track option | As fast as 48 hours in ideal cases | Only available for online incorporation using standard Crea y Crece model bylaws — not suited to every business |
Ongoing accounting and compliance costs — quarterly tax filings, annual accounts, payroll if you hire staff — run separately from setup costs and depend on the volume of activity.
FAQ
Do I need to live in Spain to register an SL?
No. Non-residents can incorporate an SL without living in Spain, either by traveling to sign the deed at the notary or by granting power of attorney to a representative who signs on their behalf.
How much share capital do I actually need?
The legal minimum is €1, but until the company reaches €3,000 in capital, 20% of annual profits must go into a legal reserve and shareholders carry personal liability for any shortfall on liquidation. Most advisors recommend incorporating with €3,000 to sidestep that.
Can I register the company before I have my residence permit?
Yes — company registration and residence status are separate processes. Many clients incorporate an SL as part of building the business case for a route like the Startup Visa, rather than waiting for residency first.
USDoes owning a Spanish SL create US tax reporting obligations?
Often, yes. US citizens who own a foreign corporation may trigger reporting requirements such as IRS Form 5471, and there are other compliance layers depending on ownership percentage and company activity. We're not US tax advisors, so we always recommend pairing Spanish company formation with a cross-border accountant who handles US filings — we're happy to make introductions.
UKShould I set up a UK company or a Spanish SL?
It depends on where the business will actually operate, who the clients are, and your personal tax residency plans. Running a UK Ltd while living in Spain can create its own complications around permanent establishment and where profits are taxed. This is genuinely a case-by-case question, and we recommend working through it with a specialist who understands both UK and Spanish tax positions before deciding on structure.
What's the difference between an SL and registering as an autónomo?
An autónomo is a sole trader structure with no legal separation between you and the business — your personal assets are exposed to business debts. An SL is a separate legal entity with limited liability, more suited to businesses with employees, investors, or meaningful commercial risk.
