Employer costs in Spain: social security, payroll taxes and the true cost of hiring

A foreign company decides to hire its first employee in Spain. HR runs the numbers based on the agreed gross salary — and then discovers the actual total employment cost is 30–35% higher. This gap between gross salary and total cost catches almost every international employer entering the Spanish market for the first time. This guide breaks down every component of the employment cost in Spain, so you can model it accurately before you hire.

The structure of employment costs in Spain

The total cost of an employee in Spain has three main components:

• Gross salary agreed in the employment contract
• Employer social security contributions — paid by the employer on top of the gross salary
• Additional statutory costs: pay in lieu of holidays, extra payments, severance provisions

The employee also pays social security contributions and income tax (IRPF) — but these are deducted from their gross salary and are not an additional cost to the employer. What the employer pays is the gross salary plus the employer’s social security contributions.

Employer social security contributions in Spain

Spain’s social security system is funded by contributions from both employers and employees, calculated as a percentage of the employee’s contribution base (base de cotización) — essentially the gross salary, within statutory minimum and maximum bands.

The contribution base has a statutory minimum (linked to the Minimum Interprofessional Wage — SMI, €1,134/month in 2025) and a maximum (€4,909.50/month in 2025). Salaries above the maximum cap have contributions calculated only up to the cap — making high earners relatively cheaper from a social security perspective.

The full cost model: an example

The 14 salary payments

Spanish employment law establishes a minimum of 14 salary payments per year — 12 monthly payments plus two mandatory extra payments (pagas extraordinarias), typically in June and December. The extra payments are equal to one month’s salary each and are included in the annual gross salary. Some collective bargaining agreements or individual contracts pro-rate the extra payments across 12 monthly instalments (paga prorrateada) instead of paying them as lump sums — but the total annual amount is the same.

Statutory leave and its cost implications

Spanish labour law establishes minimum leave entitlements that affect the real cost of employment:

• Annual paid holiday: minimum 30 calendar days (22 working days) per year — employees are paid their normal salary during leave, so this represents 30 days of paid salary with no productive output
• Public holidays: 14 days per year (8 national + up to 6 regional/local) — paid but non-working
• Sick leave (baja por enfermedad): the employer pays 60% of the contribution base from days 4–15 of illness; from day 16, Social Security takes over (75%). Temporary incapacity can last up to 365 days, creating significant indirect costs for extended absences
• Maternity/paternity leave: 16 weeks each, paid by Social Security — the employer typically bears no salary cost during this period but must manage the absence

Severance costs: Spain’s most misunderstood employment cost

Spain has one of Europe’s more generous severance frameworks — and it is frequently underestimated by foreign employers:

Dismissal for objective reasons (economic, technical, organisational)

• Severance: 20 days’ salary per year of service, capped at 12 months’ salary
• Notice period: 15 days (or payment in lieu)
• Requires formal written notice and documentation of the objective reasons

Unfair dismissal (despido improcedente)

• Severance: 33 days’ salary per year of service for periods worked after 12 February 2012; 45 days for periods before that date — capped at 42 months’ total
• The employer chooses between paying severance or reinstating the employee
• If the employer fails to follow the correct dismissal procedure — even for a justified dismissal — the dismissal is automatically classified as unfair

For financial planning purposes, foreign employers should model a severance provision of 33 days per year of service as a contingent liability from the moment of hiring. For a mid-level employee earning €40,000 gross with 5 years of service, the severance exposure on unfair dismissal is approximately €18,333.

Collective bargaining agreements (convenios colectivos)

Most Spanish employees are covered by a sector-level collective bargaining agreement (convenio colectivo) — a legally binding agreement between employer associations and trade unions that sets minimum conditions for the sector. The convenio establishes:

• Minimum salary scales by professional category — which often exceed the SMI significantly
• Additional leave entitlements beyond the statutory minimum
• Specific overtime, shift, and night work premiums
• Additional severance provisions in some sectors

Foreign employers must identify which convenio colectivo applies to their Spanish employees based on their activity sector and the employees’ professional category. Applying the wrong convenio — or ignoring it — creates retroactive salary and benefit claims.

Options for foreign companies hiring in Spain

Option 1: incorporate a Spanish entity and hire directly

The standard route: the Spanish SL or branch is the legal employer. Full control over the employment relationship, lower cost per employee at scale, but requires payroll infrastructure and monthly compliance obligations (Modelo 111, Social Security filings, SEPE notifications).

Option 2: Employer of Record (EOR)

An EOR is a third-party company that becomes the legal employer in Spain on behalf of the foreign company. The EOR handles all payroll, social security, and compliance obligations — the foreign company directs the day-to-day work of the employee. EOR services are well-suited for companies hiring one or two employees in Spain before committing to a local entity, or for short-term project-based hiring. Cost: typically a monthly fee of €400–€800 per employee on top of all employment costs.

Option 3: engage as autónomo (self-employed)

Engaging a Spanish worker as a self-employed contractor rather than an employee eliminates employer social security contributions and most statutory obligations — but only if the relationship is genuinely self-employed. Spanish labour law applies a presumption of employment when there is exclusivity, fixed hours, use of the company’s tools, and direction and control by the company. False self-employment (falsos autónomos) is an active enforcement priority of Spain’s Labour Inspectorate, with significant penalties for reclassification.

Frequently asked questions

Is there a minimum wage in Spain?

Yes. The Salario Mínimo Interprofessional (SMI) for 2025 is €1,134 per month in 14 payments — €15,876 per year gross. No employee can be paid less than this amount. Many sector convenios set higher minimums for specific professional categories.

Do foreign employers need a Spanish payroll system?

Yes, if they are the legal employer. Spanish payroll must comply with specific formats for payslips (nóminas), Social Security filing (Sistema RED), and withholding tax declarations (Modelo 111). Most foreign companies either use a Spanish payroll provider or outsource the full payroll function to a local asesoría or accounting firm.

What are the penalties for payroll non-compliance in Spain?

Spain’s Labour Inspectorate (Inspección de Trabajo y Seguridad Social) actively audits payroll compliance. Penalties for undeclared or incorrectly declared employment range from €626 to €6,250 per infraction for serious violations, with surcharges for unpaid Social Security contributions plus interest at 7.25% per annum. Repeat violations and deliberate non-compliance can result in sanctions at the upper end of the range.
