Set up a company in Spain. Run it like an operation, not a filing.
A practical guide for founders, CEOs and boards on how to set up a company in Spain that can sell, hire and report from the start. With a senior team that coordinates the set-up with the notaries, law firms and advisers who carry out each step.

Incorporating a company in Spain is the easy part. Turning it into a business that signs contracts, invoices, hires and reports to the parent is where foreign companies setting up in Spain lose months.
The filings follow a known sequence. The decisions around them do not, and they belong to the board, not to the notary.
02 / Decisions
Five decisions before you incorporate.
Decision 01
What Spain is for in the group
An EU hub, a sales market or a talent centre each call for a different structure, team and budget. Agree the role first; the entity should follow it.
Decision 02
Build, buy or partner
A greenfield subsidiary gives full control but starts from zero. An acquisition or alliance can bring customers and people sooner, with integration work instead.
Decision 03
Governance
Decide who sits on the local board, which powers of attorney are granted and to whom, and how the subsidiary reports to the parent. Clear limits avoid both paralysis and surprises.
Decision 04
Capital and cash runway
The legal minimum capital is a floor, not a plan. Fund the subsidiary for its cash runway to break-even, including the weeks before the bank account and first invoices are live.
Decision 05
Who leads the country from day one
Someone must be accountable on the ground for daily decisions, signatures and the bank relationship. If that person is not hired yet, plan how the gap is covered.
03 / First 100 days
The first 100 days.
A phased operating plan keeps the incorporation, the bank and the business moving in parallel. The phases overlap; the sequence matters more than the dates.
Phase 1
Bank and cash
- Start bank onboarding early: KYC on foreign parents and beneficial owners can take weeks.
- Set payment flows, signatories and intercompany funding before the first invoice.
Phase 2
First customers and partners
- Turn the business plan into a pipeline of named customers and partners.
- Align contracts and pricing with what the entity can legally sign and invoice.
Phase 3
First hires
- Have the employer registration and the employment framework ready before the first offer.
- Hire the roles the plan needs first, not the ones easiest to fill.
Phase 4
A dashboard for the board
- Agree a short monthly report for the parent: cash, pipeline, hiring and open filings.
- Use it to decide, not only to inform.
We then support your team through its first months of operation. This is the core of our market entry service.
04 / Legal steps
The legal steps, in one box.
Indicative timelines; not a commitment.
- Vehicle: most foreign companies use a Spanish S.L. wholly owned by the parent (S.L.U.); €1 minimum capital since Ley 18/2022.
- NIE/NIF: NIE for foreign directors and shareholders, NIF for a foreign parent company: 2–6 weeks.
- Notary and registry: public deed before a Spanish notary, then filing with the Registro Mercantil: 1–3 weeks.
- Tax registration: census declaration (form 036) for corporate tax and VAT; general corporate tax rate 25%.
- Social Security: employer registration with the TGSS before the first hire. Together with tax: 1–2 weeks.
- Foreign investment: post-investment declaration to the Spanish Foreign Investment Register (form D-1A) where applicable.
- Common planning range to invoice and hire: around 6–12 weeks.
Actual timelines depend on authorities, banks and third parties and cannot be guaranteed. Your lawyers and notaries handle the filings; we coordinate the sequence and follow up on timing with each of them.
05 / What goes wrong
Where foreign companies lose time.
Delays rarely come from the law. They come from operations:
- 01No one accountable on the ground. Documents wait for signatures and nobody chases.
- 02Bank onboarding treated as an afterthought. Without an account there is no capital, no payroll and no invoicing.
- 03Structure chosen before the plan, then redone months later.
- 04Hiring before the employment framework is ready.
- 05No reporting line to the parent. The board learns about problems late.
- 06Confusing incorporation with an operating business. A registered company still needs customers, partners and people.
06 / Questions
Frequently asked questions.
How long does it take to set up a company in Spain?
The incorporation itself can take days to a few weeks. For a foreign-owned company, a common planning range is around 6–12 weeks until it can invoice and hire, though this depends on authorities and banks and is not guaranteed.
Do I need to be in Spain to incorporate?
Not necessarily: most steps can be done through a power of attorney. Running the company still requires someone accountable locally.
Should we open a subsidiary or acquire a company in Spain?
It depends on what Spain is for in the group and how fast you need customers and people. A subsidiary gives control from a clean start; an acquisition or alliance trades speed for integration work. See M&A.
What should be ready before the first hire?
Employer registration with the Social Security, the applicable employment framework, payroll and a bank account. Then hire against the business plan.
Does Year One Partners incorporate the company?
No. We coordinate with the notaries, partner law firms, banks and tax advisors who handle incorporation and filings; we do not act as a gestoría or provide a registered office.

Scope
What we are, and what we are not.
Senior strategic advice and interim leadership for setting up and operating in Spain. We are not a law firm, an audit firm or a regulated investment firm, and we do not provide legal, audit or regulated investment services. We coordinate specialists without replacing them. We do not provide staff, recruitment or placement services.
Interim mandate
Where you need someone in the seat on the ground, an interim mandate covers it: building the first customer and partner pipeline, coordinating the entity's set-up with the notaries and law firms who carry it out, hiring the first team and reporting to your board. Each mandate is a Year One Partners engagement, always led by our Founder & CEO; where the case requires it, he is supported by an independent senior collaborator working for Y1P, coordinated by him. Y1P remains responsible for the scope, the deliverables and how the work is organised.
