📊 Financial breakdown of overtime
Overtime hours are the hours you work beyond your standard daily or weekly working schedule. In Spain, all overtime must be recorded daily by the employer and compensated either financially or through paid time off.
⚖️ Overtime categories and surcharge rates in Spain 2026
Spanish labor law states that the price of an overtime hour cannot be lower than your ordinary hourly rate:
- Standard overtime (horas comunes): Voluntary hours worked to cover production peaks or busy periods. The surcharge is determined by your collective bargaining agreement (typically between 25% and 75% above your ordinary rate).
- Force majeure overtime (fuerza mayor): Mandatory hours worked to prevent or repair damage from accidents, fires, floods, or urgent production issues.
- Night overtime: Standard night shift rules apply (usually a 25% surcharge minimum) if the overtime occurs between 22:00 and 06:00.
📐 Statutory limits on overtime hours
The Workers’ Statute limits standard overtime to a maximum of 80 hours per year for full-time employees. This limit is prorated for part-time workers. Overtime hours that are compensated with rest days within 4 months of being worked do not count toward this 80-hour limit. Force majeure hours are also excluded from this limit.
💰 Social security contributions on Spanish overtime
In Spain, overtime hours are subject to a special contribution rate to the social security system, paid by both the employee and employer:
| Overtime Category | Employee Deduction | Employer Contribution | Purpose |
|---|---|---|---|
| Force Majeure | 2.00% | 12.00% | Special hazard coverage |
| Standard Overtime | 4.70% (Contingencias Comunes) + 2.00% (Unemployment/Training) = 6.70% | 23.60% + 7.30% = 30.90% | General public contribution |
This social security deduction is taken from your gross overtime pay, reducing your net earnings.
📐 How to calculate your regular hourly wage
To find your regular hourly wage, divide your gross annual salary by the annual hours specified in your collective bargaining agreement (the legal maximum is 1,826 hours per year for a standard 40-hour week).
- Regular hourly rate (€25,000.00 / 1,800): €13.89
- Overtime rate (with a 50% surcharge): €20.83
- For 10 standard overtime hours: €208.30 gross earnings
