Company Formation in Spain
Don’t let setting up your business turn into a legal or tax nightmare
Setting up a company in Spain requires legal, tax, labour and corporate expertise.
And while it might look straightforward at first glance, many businesses make mistakes during the early stages that lead to serious complications later on.
At GCO, we handle the entire company formation process from start to finish—so you can start operating sooner and with total peace of mind.
- Strategic advice on the most efficient legal structure
- Drafting of bylaws and notarial coordination

- Initial legal and tax advisory
Company Formation in Spain
It’s more than just paperwork. It’s the legal and tax foundation of your business.
Many businesses make costly mistakes right at this first step:
- What if you choose a legal structure that increases your tax burden?
- What if you miss a filing and the Tax Agency fines you months later?
- What if you sign bylaws that limit your ability to grow or bring in new partners?
- What if you lose weeks because documents were submitted incorrectly or in the wrong order?
- What if everything starts off wrong—and you end up having to redo it all, at double the cost?
Avoid mistakes that can stall your business, create unnecessary costs, or expose you to legal risk.

“Can’t we just do this ourselves—or use our usual advisor?”
Yes, and many entrepreneurs do. Or they rely on generalist advisors who offer standard templates.
The problem? Incorporation is the phase where key legal and tax decisions are made—decisions that will impact your business long-term.
Here’s what we do that most don’t:
- Help you choose the most tax-efficient legal structure, not just the default.
- Review your bylaws line by line to avoid clauses that might block you later.
- Ensure your company is ready to operate without unnecessary delays.
- Structure your tax setup from the start so you don’t overpay.
- Incorporation isn’t just paperwork—it’s strategy with legal consequences.
At GCO, we don’t replace your advisor—we complement them at the most critical stage, so you can focus on launching your business, not fixing mistakes.
