Starting a business in Spain isn’t hard. Getting it right is.
Every year, many entrepreneurs and companies enter the Spanish market full of ideas… and short on information. What begins as an opportunity often ends up bogged down in red tape, unexpected costs, and poorly designed structures.
What’s the issue?
The legal framework is complex. The bureaucracy is slow. And mistakes are expensive.
This guide isn’t just another step-by-step checklist. It’s a practical roadmap to help you make smart decisions from day one, avoid unnecessary risks, and build a company that can grow in Spain without costly setbacks.
Let’s start with what no one tells you: why do so many international ventures fail in Spain?
Spain is a great place to invest. But it’s also a place where local rules and systems can overwhelm even the best ideas if you’re not well prepared.
Here are the most common mistakes:
Choosing the wrong legal structure.
Many companies set up an SL (Limited Liability Company) thinking it’s the easiest option… until they try to scale, bring in new partners, or repatriate profits.
Overlooking tax implications — both local and international.
Without proper planning, companies end up paying more taxes than necessary.
Working with advisors who don’t know the Spanish system.
A trusted advisor from your home country may not understand Spain’s legal and tax environment. That leads to delays, compliance issues, and financial penalties.
Neglecting labor obligations.
In Spain, you can’t hire without first addressing labor risk prevention, collective bargaining agreements, and social security requirements.
Bottom line? Starting a company in Spain without expert guidance is like driving through an unfamiliar city without GPS. You might eventually get there… but it won’t be fast, smooth, or stress-free.
So, how do you set up a company in Spain properly — and profitably?
Here’s a breakdown of the process, step by step — each with critical decisions that will shape your company’s future.
1. Choose the right legal structure
SL, branch, subsidiary, sole trader… There’s no “best” option — just the one that fits your goals, partners, liabilities, and international footprint.
Strategic tip: Depending on your expansion plans, a branch or subsidiary may offer more flexibility than a local SL. And sometimes, paying slightly more in taxes saves you significant administrative headaches.
2. Obtain your NIE and digital certificate (yes, do this first)
All foreign shareholders or directors need a NIE (Foreigner Identification Number).
You’ll also need a digital certificate to handle essential tasks online — including tax filings and company registration.
Don’t underestimate this step. Delays in obtaining your NIE can set your timeline back by weeks.
3. Draft the bylaws, set the share capital, and register your company name
This is where the real planning begins. Your bylaws define how your business will operate:
Who makes the decisions? What happens if a partner wants to leave? Will you include drag-along or preemption rights?
Common mistake: Using a generic template. You might save €300 now… and lose thousands later because a poorly drafted document blocks key decisions.
You’ll also need to:
- Request official approval of your company name from the Central Commercial Registry.
- Open a bank account in the company’s name and deposit the minimum share capital (€3,000 for an SL).
- Obtain a bank certificate confirming the deposit, which you’ll need for the notary.
If you’re not based in Spain, you’re probably wondering whether this can all be done remotely. The short answer: yes, but with some caveats. We break it down in more detail here: Setting up a business in Spain: Can you do it without traveling?
4. Sign the deed before a notary and register your company
Once you have all the paperwork ready, it’s time to sign the deed of incorporation before a notary.
Then the company must be registered with the Provincial Commercial Registry.
Once that’s done, your company legally exists.
But hold on — until you have your definitive tax ID (NIF) and your tax registration is complete, you can’t start invoicing or operating.
5. Tax and labor registration: this is where operations begin
Your company must:
- Register with the Tax Agency (Agencia Tributaria) and get your definitive NIF.
- Declare its business activity (IAE code).
- Register with the Register of Intra-Community Operators if you plan to operate within the European Union
- Register with Social Security if you’ll have employees.
Key point: Mistakes here can trigger fines. Spain’s tax system includes numerous forms and strict deadlines (036, 037, 303, 111, 347…).
6. Social Security registration and hiring employees
If you plan to hire staff — now or in the future — you must:
- Obtain a Social Security Employer Code (CCC).
- Register and enroll each employee before their first day.
- Comply with occupational risk prevention regulations.
- Apply the correct collective bargaining agreement based on your activity and region.
You’ll also have to handle:
- Payroll and social contributions (TC1, TC2 forms).
- Quarterly tax filings for employee withholdings (Form 111).
- Personal income tax (IRPF) withholdings.
Critical point: Spain’s labor laws are protective. Any mistake in hiring, dismissals, or contributions could lead to significant fines or legal disputes.
After you set up? It’s time for ongoing management
Starting your company is just the beginning. From here, you’ll need to:
- Maintain accounting in line with the Spanish General Accounting Plan.
- File monthly, quarterly, and annual tax returns.
- Legalize company books and submit annual accounts.
- Manage the employment relationship: contracts, payroll, inspections, and more.
