Step by step

  • 1

    Check the premises' urban planning compatibility

    Go to official site

    Before renting or buying, check with the City Hall of Cadiz if the premises allow the activity you want to develop. This step saves you from unnecessary trouble and expenses.

    Register with the Tax Agency and Social Security

    Go to official site

    If you're not already registered as self-employed, do it first. Model 037 at the AEAT and registration in the RETA through Importass. Without this step, you can't proceed with the opening.

    Expert tip

    "If you already have a SL or SA established, you only need the company tax ID and the company's registration in the AEAT."

    Submit the responsible declaration or business license at the City Hall of Cadiz

    Go to official site

    For most commercial and service activities, a responsible declaration of opening is sufficient. For activities with greater impact (bars, workshops, industries), you need a complete business license. The Andalusian Regional Government has Single Business Windows (VUE) in the Chambers of Commerce of each province. They allow you to submit the opening and municipal permits in a coordinated manner. You can also do it online through the regional government's portal.

Frequently asked questions

What's the difference between a business license and a responsible declaration?
The responsible declaration allows immediate opening, assuming the owner complies with all legal requirements. The City Hall can verify this later. The business license requires a prior inspection by the City Hall and can take months. For most commercial and service activities, the responsible declaration is sufficient.
How much does a business license cost in Cadiz?
The cost of a business license varies depending on the City Hall of Cadiz and the type of activity. For harmless activities (offices, small shops), the municipal fee is usually between €100 and €300. For classified activities (hospitality, workshops), it can exceed €1,000 for the required technical reports.
Can I open a business from home in Spain?
Yes. Many service, consulting, or online sales activities can be done from a private residence. In that case, the 'premises' are your home, and if there's no public attendance, you usually don't need a municipal license. However, you must register with the Tax Agency and Social Security.
What happens if I open without a business license?
Opening without the required license or declaration can result in municipal fines ranging from hundreds to thousands of euros, or even the premises being sealed. Municipalities have inspectors who conduct regular checks.
Do I need to adapt the premises with construction works?
If the premises require construction works, you must submit a building license or prior notification of works at the City Hall before starting the works. Minor works (painting, light installations) usually require a prior notification. Major works need a technical project and a building license.
