Employer cost and net salary for hiring in Spain 2026

Practical summary

This guide explains, focused on Spain and fiscal year 2026, how to estimate the total cost an employer assumes when hiring and how the employee's net salary is determined. It includes official references (BOE and the Spanish Tax Agency, AEAT) and step-by-step instructions to run an informative simulation with our calculator.

Key facts (2026)

Components of the employer cost

To estimate how much the company pays to hire a person you must consider at least these elements:

1) Agreed gross salary

This is the contractual amount before deducting employee contributions or taxes. It can be annual (for example, 17,094 EUR/year if contracted at the 2026 SMI in 14 payments) or monthly.

2) Employer Social Security contributions

The employer must pay contributions to Social Security covering common contingencies, unemployment, vocational training, workplace accidents, and other items depending on the contract and regime. Exact rates and their application depend on contribution groups, contract type, sector and applicable reductions. To know the rates in force and their breakdown, consult the BOE resolution on contributions (BOE cotizaciones 2026).

We do not invent percentages here: the correct method is to apply the official rates published in the BOE and, when applicable, consider reductions or exemptions for specific types of hiring.

3) Other employer obligations and indirect costs

Some costs are not legally mandatory but are common and should be included in a realistic estimation of total cost.

4) Employee contributions and income tax withholding (which affect net pay)

The net salary the worker receives equals gross salary minus employee Social Security contributions and personal income tax withholding (IRPF). The Agencia Tributaria publishes rules and tables to calculate IRPF withholding; the withholding depends on personal circumstances, dependents, contract type and other variables (AEAT retenciones IRPF).

Step-by-step estimation method (without inventing rates)

1) Define the gross salary to be paid (e.g., SMI 2026 = 17,094 EUR/year in 14 payments). 2) Consult the BOE for the applicable employer contribution rates for the employee's contribution group and apply those percentages to the regulatory base to calculate the employer's Social Security quota (BOE cotizaciones 2026). 3) Calculate employee Social Security contributions (employee-side rates) that will be deducted from gross; include the MEI of 0.15% when applicable as indicated by the rules. 4) Calculate IRPF withholding following AEAT rules: taxable base, withholding rate according to tables and personal circumstances (AEAT retenciones IRPF). 5) Add to gross salary any employer-borne items (non-prorated extra pay, insurance, etc.). Result: total annual/monthly cost for the employer.

Illustrative example (method only)
