    Tax Registration: Model 036 or 037

    Go to official site

    Social Security Registration: RETA

    Go to official site

    Within 60 natural days (best to do it on the first day of the month), register at the RETA office in the General Treasury of Social Security. You can go to the TGSS office in C/ del Progrés, 28, or do this online with a digital certificate.

    !

    Expert tip

    "If you register before January 1st of the month, the full monthly contribution is charged for that month. If it's after, it’s prorated. Optimal: on January 1st."

    Choose Base of Contribution Based on Estimated Income

    Under the current system since 2023, the monthly contribution is adjusted to your actual net income. You must indicate an estimated annual income. This can be changed up to six times a year.

    !

    Expert tip

    "If you are a new self-employed individual, request the flat rate (€80 per month for the first 12 months extendable if below SMI). Select 'Flat Rate Request' during registration."

    Register with IAE (if applicable)

    Most self-employed individuals (annual income < €1 million) are exempt from the Business Activities Tax. If you exceed this threshold, you must register.

    !

    Expert tip

    "Almost all individual self-employeds are exempt from the IAE. You generally don't need to do any additional procedures with the Badalona City Hall in most cases."

    Consult for Available Support Programs

    Go to official site

    Catalonia offers subsidies and bonuses for new self-employed individuals through SOC (Service of Employment of Catalonia) and the Department of Enterprise. Check current calls for applications.

    !

    Expert tip

    "The SOC offers up to €10,000 in support for self-employed individuals from certain groups (youths under 30, women, long-term unemployed). As a resident of Badalona, you have access to the same calls as in the rest of Catalonia."

With the income-based contribution system, the monthly rate varies from €200 (very low earnings) to €590 (high earnings). If you are a new self-employed individual, you can apply for the temporary flat rate: €80 per month during the first 12 months, extendable if your net income is below the SMI.
Are there any support programs for self-employed individuals in Badalona or Catalonia?
Yes. In addition to the temporary flat rate offered at the national level, the Generalitat de Catalunya and the SOC offer subsidies for new self-employed individuals, especially youths under 30, women, and long-term unemployed. Check current calls on enterprise.gencat.cat.
Can I register as a self-employed individual in Badalona?
Yes. You can do the registration directly in Badalona: the AEAT Delegation is at Avenida del Maresme, 44, and the TGSS office is at C/ del Progrés, 28. There's no need to travel to Barcelona. Additionally, online procedures via a digital certificate don't require any travel.
Do I need a digital certificate for online registration?

Can I be self-employed and work as an employee at the same time?
Yes. Pluriactivity is legal. If you already contribute as a worker for another employer, there’s a bonus in the RETA contribution to avoid excessive double taxation.
