Social Security Contributions in Spain

Overview of Social Security Contributions

Spanish employers bear a significant Social Security payroll tax burden. For every employee, both the employer and the employee pay contributions to the TGSS (Tesorería General de la Seguridad Social), Spain’s Social Security treasury. The employer is responsible for calculating both shares, deducting the employee’s portion from salary, and remitting the total to the TGSS by the last working day of the following month.

For foreign companies establishing operations in Spain, the employer Social Security cost is frequently underestimated. The combined rate — approximately 30.5% employer + 6.47% employee — means that a worker on a EUR 40,000 gross salary costs approximately EUR 52,000–53,000 to the employer in total employment costs, before any other benefits.

Contribution Rates (2025)

General Regime (RGSS) — Standard Employee

Additional contributions apply to:

• Overtime hours: 12% employer + 2% employee (voluntary OT); 23.60% + 4.70% (structural OT, same as common contingencies)
• Workplace accident insurance (AT/EP): Variable rates by occupational category (epígrafe de AT/EP), ranging from approximately 0.90% to 7%+ depending on the sector’s accident risk profile

MEI Surcharge (2023–2033)

The Mecanismo de Equidad Intergeneracional (MEI) was introduced in 2023 as a surcharge to build a Social Security pension reserve fund. In 2025, the MEI rate is 0.58% employer + 0.12% employee (total 0.70%). This rate increases progressively: it rises to a total of 1.2% by 2029.

Contribution Base (Base de Cotización)

Contributions are calculated on the worker’s contribution base, which is the gross salary including all salary items but subject to certain exclusions. The contribution base has:

• A minimum floor: Cannot be less than the minimum contribution base for the worker’s professional category (which, for most categories, is tied to the SMI — EUR 1,134/month in 2024).
• A maximum ceiling: EUR 4,720.50/month in 2024 (approximately EUR 56,646/year). Earnings above this ceiling do not generate additional contributions. This also means there is an effective cap on pension entitlements.

Items Included in the Contribution Base

All salary items: base salary, supplements, overtime pay (with special rules), extraordinary payments.

Items Excluded from the Contribution Base

• Travel and subsistence allowances within AEAT-exempt limits
• Social benefits (company canteen, transport vouchers up to EUR 1,500/year, health insurance premiums up to EUR 500/worker/year)
• Pension plan contributions up to limits
• Redundancy compensation up to the statutory minimum (20 days/year, max 12 months)

FOGASA (Wage Guarantee Fund)

The Fondo de Garantía Salarial (FOGASA) is financed by the employer’s 0.20% contribution. FOGASA pays workers’ outstanding wages and severance when their employer is declared insolvent. FOGASA’s coverage is capped at:

• Unpaid salaries: Up to 120 days, capped at double the SMI/day
• Severance pay: Up to 20 days/year of service, capped at 1 year, with a daily cap

FOGASA does not substitute the employer’s obligation in non-insolvency cases; it is a last-resort fund.

RETA: Contributions for Self-Employed (Autónomos)

Self-employed workers (autónomos) pay contributions under the RETA (Régimen Especial de Trabajadores Autónomos). Since January 2023, Spain moved to a contribution-by-real-income system — autónomos now report their expected net income for the year and pay contributions based on a 15-bracket table, with regularisation at year-end.

RETA contributions cover common contingencies, professional contingencies (AT/EP), cessation of activity, and professional training. Notably, RETA still does not automatically include unemployment benefit — autónomos must opt in to cessation of activity coverage (cese de actividad), which provides a partial income replacement if the business fails, subject to conditions.

Filing: Sistema RED and CCC

Código de Cuenta de Cotización (CCC)

Before hiring, the employer registers with the TGSS and obtains a CCC (Código de Cuenta de Cotización) — the employer’s Social Security registration number. Companies with employees in multiple autonomous communities need a CCC for each territory.

Sistema RED

Monthly contribution settlements are filed electronically through the Sistema RED platform using the RLC (Relación de Liquidación de Cuotas) and RNT (Relación Nominal de Trabajadores) documents. Large companies file monthly; smaller companies may have slightly different deadlines. The payment deadline is the last working day of the month following the accrual month.

Bonus Schemes (Bonificaciones)

Employers hiring certain priority groups (unemployed over 45, young people under 30, persons with disabilities, long-term unemployed, victims of domestic violence, etc.) may be entitled to reductions in Social Security contributions for defined periods. The applicable bonuses change frequently; always verify current regulations before planning a hiring campaign.

International Posting and Double Contributions

Workers posted from Spain to another country (or posted into Spain from abroad) must determine which country’s Social Security system applies:

• Within EU/EEA: EU Regulation 883/2004 coordinates systems. A posted worker can remain on the home country system for up to 24 months with an A1 certificate.
• UK post-Brexit: A bilateral Social Security agreement between Spain and the UK applies, preventing double contributions and preserving pension coordination for periods worked in both countries.
• Non-EU countries: Spain has bilateral agreements with around 30 countries. Workers from countries without an agreement may face double contribution obligations unless specific exemptions apply.

Frequently Asked Questions

Can a company delay Social Security payments without penalty? Social Security contributions carry daily interest from the deadline. A formal aplazamiento (payment deferral arrangement) can be requested from the TGSS, subject to conditions. Unilateral delay generates automatic surcharges: 10% if paid within the following month, 20% after that, plus interest.

Are employer Social Security contributions deductible for Corporate Tax? Yes. Social Security contributions paid by the employer are a labour cost and fully deductible from the corporate tax base under standard accounting principles.

What is the maximum pension a worker can receive given the contribution ceiling? The maximum pension is linked to the maximum contribution base. In 2024, the maximum contributory retirement pension is approximately EUR 3,175/month. Workers earning above the EUR 4,720 ceiling do not accrue additional pension entitlement on the excess earnings.

If a worker is on sick leave, who pays the Social Security contributions? During incapacidad temporal (sick leave), the company continues to pay Social Security contributions for the worker’s administrative registration. However, from day 16 onwards, INSS or the mutual insurance society pays the daily sick benefit directly to the worker; the employer’s contribution base payment continues.

Do foreign companies without a Spanish entity have Social Security obligations? Yes, if they hire or retain workers in Spain. A foreign company with an employee habitually working in Spain must register as an employer with the TGSS and pay contributions. Failure to do so does not exempt the obligation — it merely creates a backlog of unpaid contributions subject to interest and penalties.
