Seguridad Social (Spanish social security)
Spain's social-insurance scheme — 6.35% employee contribution on brut up to the base máxima.
Seguridad Social is Spain's social-insurance scheme — funds public health care, the state pension, and unemployment benefit (paro). For an employee on a standard contract, the combined employee share is 6.35% of brut earnings: 4.7% for the contingencias comunes (pension + sickness), 1.55% for desempleo (unemployment), and 0.1% for Formación Profesional.
The 6.35% applies up to the annual base máxima — €56,646 in 2025 — above which the cap kicks in and the percentage no longer rises. The employer pays a much larger share (~30%) on top, including a higher contingencias comunes rate (23.6%) plus FOGASA + accidents insurance.
On the bulletin (nómina) it appears as a separate line. The site's Spain calculator applies a flat 6.35% across the full brut as a v0 simplification; the base-máxima cap arrives in a future release.
