Self-employed quota FAQ

How is the self-employed quota calculated since 2023?

Since 2023 (RDL 13/2022), the quota is based on actual net income, not a freely chosen base. There are 15 brackets with minimum and maximum contribution bases. The quota results from applying 31.30% to the chosen base within your bracket.

Can I change my contribution base during the year?

Yes, up to 6 times a year if your income changes. Changes are requested through the TGSS RED system.

Is there a flat rate for new self-employed workers?

Yes. New self-employed workers (or those without registration in the previous 2 years) can opt for a flat rate of 80 EUR/month for the first 12 months, extendable for 12 more months if net income is below the minimum wage.
