💼 Overview — The EU's Fourth Economy
Spain is the EU's fourth-largest economy (roughly €1.6 trillion GDP), behind Germany, France and Italy. In global terms it ranks around 14th–15th, comparable to Australia or Mexico. Growth over 2024–2025 outpaced the EU average, driven by tourism, services, renewable energy, and a strong post-pandemic labour market rebound. Corporate tax sits at 25%, with reduced rates for smaller companies and a special 15% "startup" rate under the 2022 Startup Law.
For a foreign entrepreneur, Spain offers three big things: full EU market access, a Latin-American gateway (shared language and centuries of business ties), and, since October 2022, a company-formation regime that is meaningfully easier and cheaper than it was five years earlier. The Ley Crea y Crece (Law 18/2022) cut the minimum share capital for a Sociedad Limitada from €3,000 to just €1 — with strings attached — and the CIRCE fast-track can incorporate a standard company in 5–10 working days instead of 4–8 weeks.
🏗️ Starting a Company — What Actually Happens
For foreigners, the default vehicle is a Sociedad Limitada (S.L.) — the Spanish equivalent of a US LLC or a UK Ltd. There is 100% foreign ownership allowed (no local partner needed), no residency requirement to be a director or shareholder, and a single-shareholder S.L. is fine (called an SLU — Sociedad Limitada Unipersonal).
The Eight Steps
- NIE for every foreign shareholder and director. The Número de Identidad de Extranjero is the foreign-identity number. You get it at a Spanish consulate abroad (2–6 weeks, ~€10 fee), or in Spain through a power of attorney. Without it, no notary will sign anything.
- Company name certificate (Certificación Negativa de Denominación Social) from the Registro Mercantil Central. Submit three possible names, get the approved one back in 1–3 business days. Fee ~€13–20.
- Open a Spanish bank account in the company-in-formation's name. This is consistently the slowest step for foreign owners — Spanish banks apply enhanced KYC checks on foreign shareholders. Start it the moment you have a provisional NIF. 2–8 weeks.
- Deposit the share capital. €1 minimum under Crea y Crece — but see the catch below. Bank issues a deposit certificate.
- Sign the incorporation deed (escritura pública) before any Spanish notary. You can attend in person or grant a power of attorney (POA) so a Spanish lawyer signs for you. This is when the company legally exists. Fee ~€150–400.
- Provisional NIF (tax number) is issued immediately after the notary deed. For an S.L. the NIF starts with the letter B.
- Registration at the Registro Mercantil (provincial commercial registry). This makes the incorporation public and confers full legal personality. 2–4 weeks. Fee ~€200–400.
- Final NIF + Modelo 036 tax registration + Social Security registration. Now you can invoice, hire, and open the fully operational bank account.
Realistic Timeline & Cost
| Item | Standard S.L. | CIRCE fast track |
|---|---|---|
| Total time (with all documents ready) | 4–8 weeks | 5–10 working days |
| Setup fees (notary + registry + certificate) | €600–1,500 | Same fees, less friction |
| Legal/gestor advisory (optional but common) | €1,000–3,000 | €500–1,500 |
| Realistic year-1 all-in | €5,000–8,000 (formation + accountant + director's autónomo Social Security @ ~€310–370/month + accounting @ ~€150–400/month + annual accounts filing) | |
⚠️ The €1 Capital Catch
A €1 S.L. is legally possible but not usually a good idea. Under the Crea y Crece regime, until paid-in capital reaches €3,000, you must (a) allocate at least 20% of annual profit to a legal reserve every year, and (b) shareholders remain personally liable for the €3,000 - subscribed capital difference if the company goes into insolvent liquidation. Banks, landlords and serious counterparties tend to look sideways at a €1 balance sheet. Most Spanish lawyers still recommend the full €3,000 unless capital is genuinely scarce.
📋 Taxes & Ongoing Compliance
| Tax | Rate (2026) | Notes |
|---|---|---|
| Corporate tax (IS) | 25% general | Modelo 200, filed July for prior year |
| IS — micro (turnover <€1M) | 19% first €50k, 21% above | Introduced by Ley 7/2024 |
| IS — reduced-dimension SME (€1M–€10M) | 23% | Phasing in |
| IS — new company special rate | 15% | First profitable year + next; startup certified companies for 4 years |
| VAT (IVA) | 21% standard | Reduced 10% and 4% rates for food/books/medicine. Quarterly Modelo 303. |
| Social Security (director-autónomo) | ~€310–370/month min | Higher than regular autónomo; scales with declared income |
Also to know: Spain has a Beckham Law — a special expat regime that allows qualifying inbound workers to pay a flat 24% income tax rate for up to six years. And the 2023 Digital Nomad Visa is now a major route for non-EU remote workers.
📈 The Stock Exchange — BME & the IBEX 35
Spain's main equity market is the Bolsa de Madrid, part of BME (Bolsas y Mercados Españoles) — which also runs regional exchanges in Barcelona, Bilbao and Valencia. In 2020, Swiss operator SIX Group acquired BME in a €2.6 billion deal, so the Spanish exchange is now Swiss-owned.
The benchmark index is the IBEX 35 — 35 largest and most liquid stocks by market capitalisation, weighted by free float. It launched in 1992. The index has been overshadowed for a decade or so by the Euro Stoxx and by Germany's DAX, but 2024–2025 saw it as one of Europe's better performers, largely thanks to Santander and BBVA's strong Latin American exposure and Inditex's continued growth.
A candid observation: the IBEX 35 is bank-heavy and utility-heavy compared to say the CAC 40 or DAX. Retail (Inditex) is a giant weight, and technology is under-represented. There is no Spanish equivalent of an SAP, ASML or LVMH.
🏢 The Companies That Define the Economy
A short list of the Spanish corporates that actually matter — the ones that show up in every conversation about the country's economy:
🛍️ Inditex
Fashion retail. Owns Zara, Massimo Dutti, Pull&Bear, Bershka, Stradivarius, Oysho and Zara Home.
Founded 1963 by Amancio Ortega in Arteixo (Galicia). One of the world's three largest apparel groups. Ortega, briefly the world's richest person in 2017, remains among the top 20.
🏦 Banco Santander
Global bank. Eurozone's third-largest bank by market cap.
Founded 1857 in Santander, Cantabria. Massive Latin American exposure — Brazil is its single largest market. UK operations via the former Abbey National acquisition.
🏦 BBVA
Second-largest Spanish bank. Strong in Mexico and Turkey.
Formed 1999 by merger. Its 2024–2026 attempted hostile takeover of Sabadell was a political and regulatory saga that dominated Spanish financial news.
📞 Telefónica
Telecom incumbent. Operates Movistar (Spain), O2 (UK, JV), Vivo (Brazil).
Founded 1924. Government took a strategic stake via SEPI in 2023 after Saudi PIF built a large position.
⚡ Iberdrola
Renewable-energy utility. World's largest wind-power operator by installed capacity.
Bilbao-based. Owns Scottish Power (UK), Avangrid (US), and Neoenergia (Brazil). The clean-energy champion of the IBEX.
⛽ Repsol
Oil & gas major. Fully integrated — exploration through petrol stations.
Founded 1987 out of the state oil monopoly. Pivoting hard into renewables and EV charging, but still fundamentally an oil company.
🚄 Ferrovial
Infrastructure. Airports (Heathrow stake historically), toll roads worldwide.
Controversially moved its holding company to the Netherlands in 2023, a decision that triggered a national row.
☀️ Acciona
Sustainable infrastructure & renewables. Big in wind, water treatment, transport.
Family-controlled (Entrecanales). One of the earliest movers in utility-scale renewables.
🚀 The Startup Scene
Madrid, Barcelona, and — increasingly — Málaga (thanks to Málaga TechPark and the Google startup campus opened in 2023) are Spain's three main startup hubs. Valencia and Bilbao follow. Spain ranked #1 worldwide for digital nomads in 2025, and the 2023 Digital Nomad Visa opened a clean path for non-EU remote workers.
Notable Spanish startups and unicorns:
- Cabify (Madrid, 2011) — Ride-hailing app, big across Latin America.
- Glovo (Barcelona, 2015) — Food and courier delivery. Acquired by Germany's Delivery Hero.
- Wallbox (Barcelona, 2015) — EV charging hardware. NYSE-listed via SPAC in 2021.
- TravelPerk (Barcelona, 2015) — Business travel platform.
- Fever (Madrid, 2014) — Entertainment discovery, big in New York and London.
- Jobandtalent (Madrid, 2009) — Temp-work marketplace.
The Ley de Startups (Law 28/2022) — the "Startup Law" — offers ENISA-certified innovative startups the reduced 15% corporate tax rate for up to four years, plus meaningful stock-option tax reforms and easier hiring of foreign talent.
✍️ An Honest Note
EDITOR'S NOTE — Radim Kaufmann
Spain is easier to start a company in than it used to be — and harder to run a company in than the headline numbers suggest. The formation-in-a-week story is real: my own last S.L. took eight working days via CIRCE. But the ongoing side is where the friction lives. Autónomo social security for the working director eats €300+ a month before you earn a single euro. Quarterly VAT and quarterly income-tax pre-payments run in parallel. A gestor (part accountant, part bureaucratic translator) is not optional if you value your time. And the Spanish banking system, in my experience, treats every foreign-owned entity as a compliance problem to be interrogated for six weeks before onboarding. Do the S.L. if the market is right. Do it with a lawyer and a gestor from day one. Do not do it with a €1 balance sheet.
