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 from your registration in the RETA. After this period, contributions are calculated based on estimated net earnings (effective since 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 the conditions at your SEPE office before registering.
What specific support does Castilla y León offer for self-employed individuals?
The Junta has a rural entrepreneurship program that includes additional subsidies for self-employed individuals setting up businesses in municipalities with fewer than 2,000 inhabitants. There are also tax rebates on the regional IRPF for new self-employed individuals in the first year and ADE offers micro-loans without collateral for projects under 25,000€.
What IAE code should I choose?
The IAE code identifies your economic activity with Hacienda. Choose the one that best describes what you do. The AEAT has a search tool on its website. If you have multiple activities, you can register under several codes simultaneously.
When do I start paying self-employed contributions?
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 prorated amount. That’s why it’s best to register on the 1st.
