The Real Net Income Contribution System (RETA)
Under Royal Decree-Law 13/2022, all self-employed workers in Spain (trabajadores autonomos) must pay Social Security contributions based on their projected net annual business yields (rendimientos netos reales).
Annual Regularization (Regularizacion Anual)
At the close of each fiscal year, the Seguridad Social cross-references registered contributions with actual tax declarations submitted to the Agencia Tributaria:
- If you overpaid during the year relative to your actual earnings, the Seguridad Social refunds the excess automatically.
- If your earnings exceeded your chosen tier base, you will receive an adjustment notice to settle the difference.
- Contributions paid to RETA are 100% deductible from gross income when calculating Personal Income Tax (IRPF).
