Social Security contributions (cotizaciones a la Seguridad Social) are mandatory monthly payments made by both employers and employees to the TGSS (Tesorería General de la Seguridad Social). They fund Spain's pension system, unemployment benefits, healthcare, sickness leave, maternity and paternity leave, and workplace accident insurance. In 2026, employer contributions are 30.65% of the contribution base in fixed rates plus the workplace accident premium, about 32% for office staff on a permanent contract.
In practice
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. In 2026 the combined rate for a permanent contract is about 32% employer (30.65% in fixed rates plus 1.50% for workplace accidents in office jobs) + 6.50% employee, so a worker on a EUR 40,000 gross salary costs approximately EUR 52,900 to the employer in total employment costs, before any other benefits.
Contribution Rates (2026)
General Regime (RGSS) — Standard Employee
| Concept | Employer | Employee |
|---|---|---|
| Common contingencies (contingencias comunes) | 23.60% | 4.70% |
| Unemployment (desempleo) — general | 5.50% | 1.55% |
| Unemployment — fixed-term contract | 6.70% | 1.60% |
| Professional training (formación profesional) | 0.60% | 0.10% |
| FOGASA (wage guarantee fund) | 0.20% | 0.00% |
| MEI (mechanism of intergenerational equity) | 0.75% | 0.15% |
| Total (permanent contract, before AT/EP) | 30.65% | 6.50% |
Additional contributions apply to:
- Overtime hours: 12% employer + 2% employee (overtime due to force majeure); 23.60% + 4.70% (all other overtime)
- 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 (1.50% for office staff)
MEI Surcharge (2023–2050)
The Mecanismo de Equidad Intergeneracional (MEI) was introduced in 2023 as a surcharge to build a Social Security pension reserve fund. In 2026, the MEI rate is 0.75% employer + 0.15% employee (total 0.90%). It rises by 0.10 points a year: 1.00% in 2027, 1.10% in 2028 and 1.20% in 2029 (1.00% employer + 0.20% employee), and stays at 1.20% until 2050.
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 1,221/month in 14 payments in 2026). In 2026 the minimum base is EUR 1,424.40/month for groups 4 to 7, and EUR 1,989.30, EUR 1,649.70 and EUR 1,435.20 for groups 1, 2 and 3.
- A maximum ceiling: EUR 5,101.20/month in 2026 (approximately EUR 61,214/year). Since 2025, the part of the salary above this ceiling pays the solidarity contribution (art. 19 bis LGSS): in 2026, 1.15% (0.96% employer, 0.19% employee) on the part between EUR 5,101.21 and EUR 5,611.32 a month, 1.25% (1.04% + 0.21%) between EUR 5,611.33 and EUR 7,651.80, and 1.46% (1.22% + 0.24%) above EUR 7,651.80. It does not increase pension entitlement, so there is still an effective cap on pensions.
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.
| Net income range | Monthly fee at the minimum base (2026) |
|---|---|
| Up to EUR 670/month | EUR 206 |
| EUR 670–900/month | EUR 226 |
| EUR 900–1,166.70/month | EUR 268 |
| EUR 1,166.70–1,300/month | EUR 300 |
| EUR 1,300–1,700/month | EUR 303 |
| EUR 1,700–1,850/month | EUR 360 |
| EUR 1,850–2,030/month | EUR 381 |
| EUR 2,030–2,330/month | EUR 401 |
| EUR 2,330–2,760/month | EUR 427 |
| EUR 2,760–3,190/month | EUR 453 |
| EUR 3,190–3,620/month | EUR 479 |
| EUR 3,620–4,050/month | EUR 504 |
| EUR 4,050–6,000/month | EUR 546 |
| Above EUR 6,000/month | EUR 607 |
The figures apply the 2026 total RETA rate of 31.50% to the minimum base of each bracket. The self-employed person may choose a higher base within the bracket (up to EUR 5,101.20 in the two top brackets).
RETA contributions cover common contingencies, professional contingencies (AT/EP), cessation of activity, professional training and the MEI. Cessation of activity cover (cese de actividad), the self-employed counterpart of unemployment benefit, has been mandatory since 2019 (LGSS art. 327.1); it provides a partial income replacement if the business stops, 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 2026, the maximum contributory retirement pension is EUR 3,359.60/month in 14 payments (EUR 47,034.40/year). Workers earning above the EUR 5,101.20 ceiling do not accrue additional pension entitlement on the excess earnings, even though that excess now pays the solidarity contribution.
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.
