Salario Mínimo Interprofesional en 2026: how much you earn per month and per year

What is the SMI (Salario Mínimo Interprofesional)?

The Salario Mínimo Interprofesional (SMI) is the legal minimum gross salary in Spain. For 2026 the official SMI is set at 1,221 EUR per month when paid in 14 payments, which results in a gross annual amount of 17,094 EUR. These numbers are the statutory floor for full‑time workers; collective agreements and employer decisions can set higher minimums for particular sectors or regions.

Monthly vs annual SMI: how the 14-payment system works

• Gross monthly amount in 14 payments: 1,221 EUR.
• Gross annual amount: 17,094 EUR (1,221 EUR × 14).

Many employees in Spain receive 14 payments: 12 monthly payments plus two extra payments (commonly called the July and December extras). If an employer pays the annual SMI across 12 monthly instalments, the monthly gross equivalent is the yearly total divided by 12. For the 2026 SMI that is:

• 17,094 EUR ÷ 12 = 1,424.50 EUR gross per month (if the employer spreads the annual SMI over 12 months).

Which system applies to you depends on your contract and company practice. Both methods are valid as long as the total gross pay for the year meets or exceeds the statutory annual SMI equivalent.

Part‑time work, prorated SMI and temporary hires

For part‑time workers the SMI is prorated according to the number of worked hours compared with a full‑time reference. Likewise, a worker who is employed only part of the year will receive the proportional fraction of the annual SMI for the days worked. Collective agreements and employment contracts must reflect the correct prorated amounts.

If you change jobs mid‑year or have several short contracts, your pay for each contract must meet the prorated minimum for the period worked.

From gross SMI to take‑home pay: what reduces the gross amount

Gross SMI is the starting point. Two main deductions reduce gross pay to net pay:

• Social Security contributions: employee contributions to Social Security are withheld at source. For 2026 the maximum contribution base used by the Social Security system is 5,101.20 EUR/month; this cap affects high earners but does not change the calculation for someone earning the SMI. Employee contribution types include standard contingencies, unemployment, professional training and others. The specific percentage withheld depends on the rules and contribution bases in force; these vary by concept and can change with regulations.

• Personal income tax (IRPF) withholding: employers withhold an estimated portion of income tax from wages. Withholding percentages depend on personal circumstances (marital status, number of dependents, other income sources, deductions, tax residency) and on the gross amount. Many employees earning the SMI have low or very low IRPF withholding rates; some may see negligible withholdings, while others with additional income could have higher withholding.

Note: taxable and withheld amounts are subject to official rules and individual situations. For precise withholding rates consult the Agencia Tributaria (AEAT) tables or use an up‑to‑date payroll calculator.

Employee “MEI” contribution (small special item)

As a specific 2026 datapoint, the employee contribution item labelled MEI is 0.15% for the year. This is one of the items that may appear on payroll slips and reduces gross pay marginally. Its application depends on the nature of the contract and the exact payroll concept descriptions.

Example scenarios (gross figures only)

• Standard full‑time with 14 payments: gross monthly 1,221 EUR; total gross for the year 17,094 EUR.
• Same annual total paid in 12 months: gross monthly 1,424.50 EUR; total gross for the year 17,094 EUR.

These examples show gross amounts; net (take‑home) pay will be lower after Social Security and IRPF withholdings, which vary by individual circumstances.

Social Security maximum base and what it means

The Social Security maximum contribution base for 2026 is 5,101.20 EUR/month. This figure is relevant mainly for higher salaries because contributions on earnings above this base are not required. It does not affect SMI earners directly, but it is an official ceiling used to calculate employer and employee contributions for higher pay brackets.

How to know what you will actually receive (net pay)

Because Social Security contributions and IRPF depend on personal circumstances and specific payroll items, the only reliable ways to get your expected net salary are:

• Check your payslip: it must show gross pay, each deduction and the resulting net pay.
• Use an up‑to‑date net salary calculator that applies current Social Security and withholding rules to your situation.
• Consult your payroll or HR department if you have questions about how your pay is split (14 vs 12 payments), extra payments, or prorated amounts.

Practical tips for employees earning the SMI

• Confirm with your employer whether you receive 14 or 12 payments and request a written breakdown of the annual total.
• Keep payslips — they are the definitive record for gross pay, deductions and net pay.
• For part‑time or temporary work, verify the prorated calculation to ensure you receive at least the legal minimum for the hours/days worked.
• If you have multiple jobs, total your annual gross income to understand possible IRPF implications.
