Spain Social Security Calculator

In 2025, Spanish employees contribute 6.48% of their gross salary to Social Security (Seguridad Social), which is automatically deducted from your paycheck. This breaks down as: 4.70% for common contingencies (CC — covers disability, maternity, retirement, survivors benefits), 1.55% for unemployment insurance (desempleo), 0.10% for vocational training (formación profesional), and 0.13% for the MEI intergenerational equity mechanism. These contributions are mandatory and apply to all employment earnings up to the maximum contribution base of €4,720.50/month. Employees are not typically given a choice in whether to contribute, though contributions are deductible from IRPF taxable income.

Spanish employers pay substantially more than employees — approximately 30.47% of the contribution base for indefinite (indefinido) employment contracts. This breaks down as: 23.60% for common contingencies (CC), 5.50% for unemployment insurance (desempleo), 0.60% for vocational training (FP), 0.20% for FOGASA (employee guarantee fund), and 0.57% for MEI. For context, if you're employed on a €2,500 gross salary, your employer pays an additional €761 per month in Social Security costs on top of your €2,500 gross, for a true all-in cost of €3,261/month. This is why total employment costs in Spain are high and may be why jobs are scarce or salaries appear lower than in lower-tax countries.

Since January 1, 2023, Spain reformed how self-employed workers (autónomos) pay Social Security through RETA (Régimen Especial de los Trabajadores Autónomos). Previously, autónomos could choose their contribution base freely (within limits) and pay a percentage. Now they declare their expected annual net income and are automatically placed into one of 15 income tranches (€0–€30,000+), each with a fixed monthly quota ranging from €200–€530/month. At the end of each fiscal year, the TGSS (Social Security administration) reconciles your estimated income against your actual declared income. If you earned more, you pay additional quota; if less, you receive a refund. This system aims to align contributions more closely with actual income and simplifies administration, though it removes flexibility.

The maximum monthly contribution base (base de cotización) for 2025 is €4,720.50/month, or €56,646 annually. This means even if you earn €60,000/month, Social Security contributions are calculated only on €4,720.50. Conversely, the minimum base is €1,323/month, aligned with Spain's SMI (Salario Mínimo Interprofesional — minimum wage). Most regular employees fall within this capped range. High earners benefit from the cap because above it, no additional SS contributions are owed — though note that other taxes like IRPF (income tax) apply to all income above the cap.

Yes, absolutely. Both employee Social Security contributions (withheld from your paycheck) and autónomo RETA quotas are fully deductible from your gross income when calculating your IRPF (Impuesto sobre la Renta de las Personas Físicas — personal income tax) liability. This means a €2,500 gross salary with €162 in Social Security contributions results in a taxable base of €2,338 for IRPF purposes. For autónomos, the RETA quota and any additional voluntary contributions are gastos deducibles (deductible expenses) and reduce your taxable net profit. This is an important tax relief that lowers your overall tax burden.
