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 12 months after registration in the RETA. After that, the contribution is calculated based on estimated net earnings for the current year (effective from 2023).
Can I combine unemployment with becoming self-employed?
Yes. You can claim full unemployment benefits to invest in your business or partially combine it. Check with your SEPE office before registering.
What specific support does Asturias offer for self-employed individuals?
IDEPA offers the Asturias Emprende program with free advice and access to incubators. It also administers the Asturian Entrepreneurship Fund with soft loans for new self-employed individuals. There are special deductions in the Asturian self-employment tax for industrial and technological sector self-employed, aligning with the regional economic restructuring.
Which IAE chapter should I choose?
The IAE chapter identifies your economic activity to Hacienda. Choose the one that best describes what you do. The AEAT has an online search tool on its e-Sede portal. If you have multiple activities, you can register under several chapters simultaneously.
When do I start paying self-employed contributions?
Starting from the first day of the month in which you register. If you register on the 1st, pay the full monthly contribution for that month. If you register mid-month, pay a proportional part. That's why it's better to register on the first day of the month.
