Business advisory in Spain
for foreign investors

Setting up or running a business in Spain as a foreigner is not straightforward. The legal structure, the tax obligations, the contracts — things don't work quite the same way as they do back home. And mistakes made early can be costly and difficult to fix.

At Sol-4 Gestión, we've been advising foreign investors and entrepreneurs on the Costa Blanca since 2001. We work in English, we know the Spanish business and legal system from the ground up, and we give you the advice you actually need.

  • 25 years on the Costa Blanca
  • English, Spanish and German
  • Response within 24 hours
  • 2,500+ operations handled

What we do

We act as a dedicated business advisor for foreign clients on the Costa Blanca and across the Valencian Community — covering the full lifecycle of a foreign business in Spain, from day one through ongoing compliance and growth decisions.

01
Dedicated Advisor

Business advisor for foreign investors

Many foreign investors arrive in Spain with a clear idea of what they want to do, but without a full understanding of how the Spanish business environment works. Which structure to choose, what the real obligations are, where the risks lie — things other advisors often don't flag until they've already become a problem.

We review your situation, identify what needs to be in place legally and fiscally, and advise on the decisions that have long-term consequences: structure, contracts, tax position, liability. This is not off-the-shelf advice. It starts with understanding your business, your country of origin, and what you're trying to build in Spain.

02
Business Setup

Business advisory services

Our advisory work covers everything a foreign investor needs to operate legally and efficiently in Spain — from the first structural decision to ongoing compliance.

  • Advising on the most suitable legal structure (SL, branch, autónomo, holding)
  • Reviewing business plans from a Spanish legal and tax perspective
  • Guiding you through company incorporation and registry obligations
  • Advising on employment law, contract obligations and liability
  • Supporting commercial negotiations with Spanish partners or clients
  • Acting as your permanent point of contact in Spain for any business matter

Most clients need someone in Spain they can call when a decision has to be made. That's the role we play.

03
Consulting

Consulting services in Spain

We combine legal, tax, and business expertise to help you make decisions that are both compliant and commercially sound.

Legal & corporate

Company formation, corporate governance, contract review, commercial disputes and shareholder agreements — handled by professionals who know Spanish mercantile law.

Fiscal

Tax structure for foreign-owned businesses, corporate income tax, VAT obligations, cross-border taxation and double taxation treaty application.

Operational

Employment contracts, payroll compliance, labour law obligations and Social Security registration — the administrative side most foreign owners underestimate.

Strategic entry

If you're evaluating whether to establish a presence in Spain, we give you a clear picture of the requirements, costs, timelines and risks — before you commit.

What our clients say

Two decades of buyers, sellers and business owners on the Costa Blanca — here's what a few of them told us, in their own words.

★★★★★

We have relied on the services of Sol-4 for a number of years. We have found them very helpful and knowledgeable when dealing with our fiscal requirements and conveyancing. Having owned a property in Benimar-Rojales, it was very beneficial to have friendly and expert staff that were local to us. Sol-4 have provided us with excellent service over the years and we are happy to recommend them to anyone.

As a couple we have used Sol-4 Gestión for about 8 years and always been happy with the service and helpful advice given by Mar and all her team. Through setting up a business, house purchase, annual taxation, deaths and so much more they have helped us navigate the Spanish system with honest, direct and straightforward advice. We recommend Sol-4 Gestión completely.

Ever since my arrival in Benijófar in 2020 I have been using the services from Sol-4. This has been for the purchase of houses, assisting on legal matters and arranging all tax matters (Suma etc.). They also helped and assisted some of my friends who arrived in Spain. All of us are very happy to recommend the company and their services — they act very professionally and directly on a very personal level. Mar Bascuñana is a very professional lawyer and knows her cases in all details with the right advice. If you need professionals and help, at Sol-4 you are on the right address, and fully recommended by me.
