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

Setting up a Sociedad Limitada (SL) — Spain’s equivalent of a limited liability company — is by far the most common way foreigners start a business in Spain: it keeps your personal assets separate from the company’s and signals credibility to clients, suppliers, and banks. But the process has its own quirks when the person signing isn’t a resident or doesn’t hold a Spanish DNI, and certain obligations kick in from day one, whether you’re invoicing yet or not. This guide walks through the essentials: getting the director’s NIE, how much capital you actually need, the notary and Commercial Registry steps, and the tax obligations you can’t afford to ignore even if the company is still dormant.

The director’s NIE and share capital: the first things you’ll need

The NIE (Foreigner’s Identification Number) is the tax ID that Spain’s Tax Agency (AEAT, roughly Spain’s equivalent of the IRS or HMRC) assigns to any foreigner who’s going to have an economic or legal relationship with the country. Without an NIE you can’t sign before a notary, nor can you appear as a director or shareholder of an SL — so it’s the first box to check. You can apply for it at a Spanish consulate in your home country or, if you’re already in Spain, at a police station or immigration office. It’s worth applying well in advance, since appointment availability and processing times vary a lot depending on the office and time of year.

As for share capital, Spanish law lets you set up an SL with a purely symbolic minimum — even €1 — thanks to a reform aimed at making it easier to start a business. That said, incorporating with capital well below the traditional benchmark of around €3,000 comes with extra obligations until you reach that threshold: by law, you must set aside a portion of profits each year into a reinforced legal reserve, and if the company is ever dissolved, shareholders face broader liability for company debts. In practice, many foreigners choose to contribute the “classic” €3,000 to sidestep those extra requirements and project a stronger image of solvency — even though €1 is technically enough to get started.

Notary, Commercial Registry, and the role of a proxy

Once the NIE is sorted and the capital decided, the process runs through three main steps: reserving the company name with the Central Commercial Registry, opening a bank account in the name of the company-in-formation to deposit the share capital, and signing the deed of incorporation before a notary. If the director or shareholders can’t travel to Spain, it’s common to grant power of attorney to a trusted advisor or lawyer who signs on their behalf — this speeds things up considerably and avoids unnecessary trips. After signing, the deed is filed with the provincial Commercial Registry for final registration, at which point the company receives its definitive NIF (Tax ID Number) and becomes fully operational. There are also streamlined online incorporation options for certain types of SL, though they’re not always practical when one of the shareholders lives abroad — it’s worth reviewing your specific case with an advisor beforehand.

Tax obligations start on day one, even if the SL isn’t invoicing yet

One of the most common mistakes foreigners make when setting up an SL is assuming that if the company isn’t generating income, there’s nothing to file. It’s actually the opposite: from the moment of registration, the SL must register for tax purposes, keep accounting records in line with Spain’s General Accounting Plan, and file Form 200 (the annual Corporate Tax return) with the AEAT every year — even if the company had zero activity for the entire fiscal year. Annual accounts also need to be filed with the Commercial Registry. Depending on the business activity, quarterly VAT or withholding tax obligations may also apply, and if you hire staff, you’ll need to register with Social Security under the appropriate scheme (for example, the self-employed RETA scheme for a director who regularly performs management duties). Missing these deadlines — even out of simple unawareness — triggers penalties and surcharges that quietly pile up while the company sits dormant.
