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 after registration in RETA. After that, contributions are calculated based on net earnings estimates for the current fiscal year (the real-income-based system since 2023).
Can I combine unemployment with self-employment?
Yes. You can claim full unemployment benefits or partially combine them while starting your own business. Check conditions at SEPE before registering.
What specific support programs does Asturias offer for self-employed individuals?
IDEPA offers the Asturias Emprende program with free advice and access to incubators. It also manages the Asturian Entrepreneurship Fund, providing soft loans to new entrepreneurs. There are special tax deductions for industrial and technological sector self-employment in line with regional economic restructuring.
Which IAE chapter should I choose?
The IAE chapter identifies your business activity for Tax Agency purposes. Choose the one that best describes what you will be doing. The AEAT has an online search tool on its website. If you have multiple activities, you can register under several chapters simultaneously.
When do I start paying the self-employed tax?
Starting from the first day of the month in which you register. If you register on the 1st, pay the full monthly fee for that month. If you register mid-month, pay a proportional amount. That’s why it’s best to register at the beginning of the month.
