Step by step

  • 1

    Check urban compatibility of the location

    Go to official site

    Before leasing or purchasing, check with the Zaragoza city hall whether the location allows the activity you want to develop. This step saves you from unnecessary delays and costs.

    Register with the Tax Office and Social Security

    Go to official site

    If you are not already registered as an individual entrepreneur, do it first. Use Model 037 at AEAT and register in RETA through Importass. This step is necessary before you can proceed with opening.

    Expert tip

    "If your company or association has already been incorporated, you only need the CIF of the entity and the registration in the Tax Office."

    Apply for a responsible declaration or business license at the Zaragoza city hall

    Go to official site

    For many commercial and service activities, you can just file a responsible declaration of opening with the Zaragoza city hall. For more impactful activities (bars, workshops, industries) you need a full business license. In Aragon, opening procedures are handled by the municipal hall and in some cases by the Government of Aragón. The Aragon Enterprise portal offers information on the necessary procedures according to your activity type.

Frequently asked questions

What is the difference between a business license and a responsible declaration?
A responsible declaration allows you to open immediately, assuming that all legal requirements are met. The city hall can verify this later. A business license requires prior inspection by the city hall and may take several months. For most commercial activities with no special impact, a responsible declaration is sufficient.
How much does a business license cost in Zaragoza?
The cost of a business license varies according to the Zaragoza City Hall and type of activity. For harmless activities (offices, small shops) the municipal fee usually ranges from 100€ to 300€. For more classified activities (food service, workshops) it may exceed 1,000€ due to required technical reports.
Can I open a business from home in Spain?
Yes. Many services, consultancy or online sales can be carried out from your private residence. In this case, the 'business location' is your home and you usually do not need a municipal license if there is no public service provision. However, you must register with the tax office and social security.
What happens if I open without a business license?
Opening without the required business or responsible declaration can lead to municipal fines ranging from hundreds to thousands of euros, as well as premises sealing. City halls have activity inspectors who conduct periodic checks.
Do I need to do works to adapt the location?
If the location needs works, you must apply for a works permit or prior communication of works with the city hall before starting work. Minor works (painting, light installations) usually can be applied through prior communication. Major works require a technical project and works permit.
