Frequently asked questions

How long does the Tarifa Plana of 80€ last for self-employed individuals?
The Tarifa Plana of 80€/month applies during the first year of registration in the RETA. After that period, contributions are calculated based on estimated net earnings for the current year (the income-based contribution system, which has been in effect since 2023).
Can I combine unemployment with becoming self-employed?
Yes. You can claim your full unemployment benefit to invest in your business or partially combine it. Check the conditions at your SEPE office before registering.
What specific support does Castilla and León offer for self-employed individuals?
The Autonomous Government has a rural entrepreneurship program that includes additional subsidies for self-employed individuals setting up in municipalities with fewer than 2,000 inhabitants. There are also tax reductions on the regional income tax for new self-employed individuals during their first year, and ADE offers interest-free micro-loans for projects under 25,000€.
Which IAE code should I choose?
The IAE code identifies your economic activity to the Tax Office. You must choose the one that best describes what you will be doing. The AEAT has a searchable database on their website. If you have multiple activities, you can register for several codes simultaneously.
When do I start paying self-employed contributions?
Starting from the first day of the month in which you are registered. If you register on the 1st, you pay the full monthly contribution. If you register mid-month, you pay a proportional amount. That’s why it is better to register on the first day of the month.
