Checking whether we can register as self-employed: the starting point

Before entering into the formalities of how to become self-employed in Spain, We need to confirm something basic: if we comply with the requirements for self-employment. This step is key to avoid problems later on and to start safely.

- Have the legal right to work in Spain, whether by nationality, residence or specific authorisation.
- To have a NIE or DNI in force.
- Be clear about what activity you are going to develop, as this will influence the next steps.
For many migrants, this is a time to review their administrative situation calmly. Not all residence authorisations allow for self-employment, so it is important to check before starting the process or find out how to modify the permit if necessary.

Once we confirm that we can do this legally, the path becomes clearer and we can move forward with greater peace of mind.
Registering with the tax authorities: defining our activity and starting in order

One of the central steps in how to become self-employed in Spain is the registration with the Inland Revenue. This formality marks the official start of our economic activity and allows us to issue invoices legally. Beyond the paperwork, this is the moment when we name and shape what we are going to do.

- Choose the IAE heading that best describes what we do.
- Define the tax system to be applied to our income.

Taking the time to understand this point - or seeking advice if we need it - is an investment in peace of mind. Because starting out with clarity is one of the best ways to taking care of our professional stability.
Social Security registration: protecting us while we are self-employed

Once the activity has been initiated with the tax authorities, we must:
- Register with the Special Regime for Self-Employed Workers (RETA).
- Choose the contribution basis based on our estimated revenues.
- Inform us about discounts or reduced fares available at the start of the activity.
This step often generates doubts because it involves a fixed monthly cost, but it is important to see it for what it is: a form of protection. Quoting is not only an obligation, it is also a way to take care of ourselves in the long term and to give stability to our professional project.

- Setting clear boundaries between work and personal life.
- Recognise when we need to stop or reorganise loads.
- Understand that saying no to certain assignments is also a professional decision.
