CALCULATOR
Autónomo cuota calculator 2026
Estimate your monthly Social Security contribution (cuota) as a self-employed autónomo in Spain, based on your net income and the tarifa plana flat rate.
Enter your net profit after the RETA flat-rate expense deduction: 7% for most autónomos, or 3% only if you're a company administrator/majority shareholder registered under that regime for ≥90 days this year (LGSS art. 308.1.c). If you're unsure which applies to you, confirm with a gestor or the Seguridad Social before entering a figure — the wrong percentage can put you in the wrong bracket.
Estimate only, based on the 2026 income-based RETA table (Orden PJC/297/2026, RDL 3/2026). Your actual cuota depends on your chosen contribution base and is subject to yearly regularización by the Seguridad Social. Not tax or legal advice.
