How to Register a Company (SL) in Spain as a Foreign Founder
A practical walk-through of forming a Sociedad Limitada as a non-resident — what you need to line up beforehand, how the paperwork actually moves, and what it costs at each stage.
Why Foreign Founders Default to the SL
The Sociedad Limitada — SL for short — is the structure almost every foreign entrepreneur ends up choosing once they're building something bigger than a solo consultancy. It's a separate legal entity, which means your personal assets sit outside the company's debts and obligations. Compare that to registering as an autónomo, where there's no legal wall between you and the business, and the appeal is obvious for anyone hiring staff, signing supplier contracts, or raising outside capital.
If you're weighing the two structures against each other rather than assuming SL is the right call, our companion guide on autónomo vs. Sociedad Limitada breaks down when each one actually makes sense. For US and UK founders specifically, the SL maps loosely onto an LLC or a private limited company back home, though the formation mechanics, tax treatment, and reporting obligations are entirely Spanish and shouldn't be assumed to mirror either system.
What to Line Up Before You File Anything
An NIE for Every Director and Shareholder
Anyone signing the incorporation deed or listed on the share register needs a Número de Identificación de Extranjero first. If you don't have one yet, start there — nearly every later step depends on it being in place.
A Certified Company Name
You submit up to five name options to the Registro Mercantil Central, which checks them against the existing company register and certifies the first one that's free. The certificate is only valid for a limited window, so don't request it too far ahead of when you'll actually use it.
Share Capital
Since the Crea y Crece reform, the legal minimum is €1. Most advisors still recommend incorporating with €3,000 in practice — below that threshold, 20% of annual profit has to go into a legal reserve each year, and shareholders can carry personal liability for any shortfall if the company winds up before reaching €3,000. Starting at the full amount sidesteps that complication.
A Registered Address in Spain
Every SL needs a domicilio social — a registered address the Commercial Registry and tax office can associate with the company. You don't necessarily need to lease office space to get one; see our comparison of virtual office vs. physical office requirements before committing to either.
The Registration Process, Step by Step
1. Reserve and Certify the Company Name
File your name options with the Registro Mercantil Central, which typically certifies an available name within a few business days.
2. Open a Business Bank Account and Deposit Capital
With the certificate in hand, open a Spanish business account and deposit the share capital. Non-residents sometimes find this step slower than expected — see our guide on opening a business bank account as a non-resident for what banks tend to ask for. The bank issues a deposit certificate that the notary will require.
3. Sign the Deed of Incorporation
The escritura de constitución sets out the bylaws, shareholder structure, and administrator appointments. You don't have to be in Spain in person for this — you can travel to sign, or grant power of attorney to someone 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 it's registered, the company legally exists.
5. Register for Tax
The last step is obtaining the company's NIF and filing the census declaration with the Agencia Tributaria, which sets up the relevant tax obligations, including VAT/IVA registration if the business will invoice for goods or services.
Costs and Timeline
These are typical ranges rather than fixed prices — actual costs depend on the capital amount, the notary you use, and whether the bylaws are standard or custom.
| Item | Typical Range | Notes |
|---|---|---|
| Notary, registry & advisor fees combined | Roughly €2,500–€4,000 | Varies with capital amount and bylaw complexity |
| Minimum share capital | €1 legal minimum; €3,000 commonly recommended | Avoids the legal reserve requirement below €3,000 |
| Standard formation timeline | 2–4 weeks | Typical for non-resident or customized incorporations |
| Fast-track option | As fast as 48 hours in some cases | Only available for standard Crea y Crece model bylaws filed online |
Ongoing costs — quarterly filings, annual accounts, payroll if you take on staff — run separately from setup and scale with how active the business is.
FAQ
Do I need to be a Spanish resident 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 someone who signs on their behalf.
Can I register the company before applying for a visa?
Yes — incorporation and residence status are separate processes. Many founders register the SL first as part of building the business case for a route like the Startup Visa, rather than waiting on residency.
USDoes owning a Spanish SL trigger US reporting obligations?
Often, yes. US citizens who own a foreign corporation may need to file forms such as IRS Form 5471, with additional layers depending on ownership percentage and activity. We're not US tax advisors, so we always pair Spanish incorporation with a cross-border accountant who handles the US side — we can make introductions if you need one.
UKIs it better to keep operating through my existing UK Ltd instead?
It depends on where the business actually operates, where clients are based, and your personal tax residency plans. Running a UK Ltd while living full-time in Spain can raise permanent establishment questions about where profits should be taxed. This is genuinely case-by-case, and worth reviewing with a specialist who understands both UK and Spanish positions before you decide.
