Setting Up an SL in Spain as a Foreigner: Costs, Timelines and Taxes

Spain remains one of the top destinations for foreigners looking to live, invest or start a business in the country, and for many of them the Sociedad Limitada (SL) — Spain’s closest equivalent to a British limited company or a German GmbH — is the structure of choice. The process is designed to be relatively straightforward, but anyone unfamiliar with the Spanish system runs into quirks that a local citizen never has to deal with: a mandatory identification number obtained in advance, a decision about share capital with real legal consequences, and tax obligations that start ticking from day one, whether the company invoices anything or not.

The director’s NIE and the share capital decision

Before even thinking about notaries or company names, any foreigner who will be a shareholder or director of an SL needs a NIE (Número de Identidad de Extranjero) — the number the Spanish administration assigns to every foreigner so they can be identified by the tax authorities, the Commercial Registry and banks. Without a NIE there is no incorporation deed, so this is usually the first step — and for anyone living outside Spain, the most time-consuming one too. It can be requested at a police station in Spain or at the Spanish consulate in the applicant’s country of residence, and it’s worth starting well in advance of any other step.

Once the NIE is sorted, a decision comes up that catches many people off guard: the legal minimum share capital for an SL is €3,000, but since the reform that introduced the so-called “SL de formación sucesiva” (successive-formation SL), it’s possible to incorporate with just €1. That symbolic euro isn’t free of strings: until the capital reaches €3,000, the company must set aside a significant share of its annual profit into a reinforced legal reserve, cannot freely distribute dividends, and if the company is wound up, the shareholders are personally liable for the shortfall up to that €3,000 figure. Many foreign entrepreneurs looking to project a solid image to banks, suppliers or clients go straight for the €3,000 option and avoid those restrictions from day one.

From the notary to the Commercial Registry: getting the SL up and running

Once the NIE is in hand, the process follows a fairly standardized path: requesting a certificate from the Central Commercial Registry confirming that the chosen company name is available, proving that the share capital has been paid in, and signing the incorporation deed before a notary, where the company’s corporate purpose, bylaws and management structure are set out. The notary then requests a provisional NIF from the AEAT (Spain’s Tax Agency), allowing the company to start operating while final registration is completed at the Commercial Registry of the relevant province — the step that gives the company full legal personality.

Costs break down into notary and registry fees — which depend on the share capital and the complexity of the bylaws — and, in practice, the fees of an accounting firm or advisor guiding the process, which is especially advisable for anyone not living in Spain or not fluent in the language and its administrative paperwork. If the NIE is already sorted and the paperwork in order, incorporation can be completed within a few weeks; for a foreigner, the real bottleneck usually comes earlier, in getting the NIE and opening a Spanish bank account remotely.

Obligations from day one, even for a dormant company

This is where most foreigners get an unpleasant surprise: incorporating the SL isn’t the end of the process, it’s the start of a calendar of obligations that runs regardless of whether the company invoices anything. From the moment it registers with the tax authorities, the company must file Form 200 — the Corporate Tax return — every year, even in years with no activity or income. Failing to file isn’t a minor oversight: it triggers the same requests and penalties from the AEAT as it would for a company trading normally. Depending on the activity, this is on top of quarterly VAT returns, withholding tax if there are paid directors or employees, and registration with the RETA (Spain’s self-employed social security scheme) when the director carries out executive functions on a regular basis and controls the company.

At Zythos Business, we often support foreign entrepreneurs through exactly this stretch that tends to go unnoticed: the day after signing the deed, when deadlines and filings that nobody explained clearly start piling up. We help sole traders and small businesses — including those arriving from outside Spain — get their accounting and tax affairs running from the very first quarter, so that setting up the company doesn’t turn the easy part into the hard part of keeping it compliant.
