Frequently asked questions

How long does the 80€ Tarifa Plana last?
The 80€/month Tarifa Plana applies for the first year of registration in RETA. After that, contributions are calculated based on estimated net earnings (the real income-based system, effective since 2023).
Can I combine unemployment with becoming self-employed?
Yes. You can fully capitalize your unemployment benefits or partially combine them with starting a business. Check the conditions at your SEPE office before registering.
What specific support does Castilla y León offer for self-employed individuals?
The Junta offers the Rural Entrepreneurship Program, which includes additional grants for self-employed individuals setting up businesses in municipalities with fewer than 2,000 inhabitants. There are also tax reliefs on the regional income tax for new self-employed individuals in their first year and micro-loans from ADE without collateral for projects under 25,000€.
What IAE chapter should I choose?
The IAE chapter identifies your economic activity with the Tax Agency. You must select the one that best describes what you will do. The AEAT has an online search tool on their e-Services platform. If you have multiple activities, you can register for several chapters simultaneously.
When do I start paying self-employed taxes?
Starting from the first day of the month following your registration. If you register on January 1st, you pay the full monthly contribution that month. If you register mid-month, you only pay a proportional amount. That's why it's best to register at the beginning of the month.
