    Registration with the Tax Office (Model 036 or 037)

Frequently asked questions

How long does the €80/month Flat Rate Tariff last for self-employed?
The €80/month Flat Rate Tariff applies for the first 12 months of registration in the RETA. After that, the fee is calculated based on the estimated net income for the current year (real income-based system, in force since 2023).
Can I combine unemployment with becoming self-employed?
Yes. You can capitalize unemployment (claim 100% of unemployment benefits once to invest in your business) or partially combine it. Consult your SEPE office before registering.
What specific aids does Andalusia offer for self-employed?
Andalusia Emprende offers free advice in all municipalities, access to CEEIs, training, and accompaniment during the first year. The Andalusia Government also manages FSE subsidies for new self-employed workers who were unemployed and has specific programs for rural areas and agricultural self-employed workers.
Which IAE chapter should I choose?
The IAE chapter identifies your economic activity with the Tax Agency. You must choose the one that best describes what you will do. The AEAT has a search tool on its electronic headquarters. If you have multiple activities, you can register in several chapters simultaneously.
When do I start paying the self-employed fee?
From the first day of the month when you register. If you register on the first day, you pay the full fee for that month. If you register mid-month, you pay the proportional fee. That's why it's recommended to register on the first day of the month.
