New SMI 2026: how the increase will affect company salaries in Spain

What changed for the SMI in 2026

The Spanish government published the new statutory minimum wage (SMI) for 2026 in the BOE. The official amounts are: 1,221 EUR per month when paid in 14 payments, which equals 17,094 EUR per year. (Source: BOE SMI 2026.) This article explains, for employees in Spain, how that increase can affect payroll, net take-home pay and what to check with your employer or the tax authorities.

Quick facts you should know

How the SMI increase affects gross wages

If your contract refers to the SMI or a wage tied to it, your gross salary will increase to meet the new legal floor. For many full-time workers paid by the month in 14 payments, the gross annual salary tied to the SMI is now 17,094 EUR. Employers must ensure that any contractual minimums, collective agreement minima or sectoral rules are respected alongside the SMI.

For part-time workers, the employer must apply a proportional calculation based on the agreed working hours. Collective agreements and specific contractual clauses can define different payment structures, but they cannot produce a gross annual salary below the legal SMI floor for the equivalent full-time job.

Impact on net pay (take-home salary)

Net pay depends on gross salary minus Social Security contributions and income tax withholdings. The SMI increase raises the gross base for those previously earning below the new floor, but it does not change withholding rules or tax brackets by itself. The actual effect on your take-home pay will depend on:

Because official withholding rates depend on individual circumstances, this article does not provide a single net-amount figure. Use the AEAT withholding tables or a payroll simulation tool to estimate net pay for your personal case.

Employer costs and company payroll budgets

When the SMI rises, employers who were paying wages at or near the previous minimum must increase gross salaries. That affects company payroll expenses in two ways:

For high earners, the Social Security maximum contribution base (5,101.20 EUR/month for 2026) limits how much contribution increases as salaries grow. For most workers near the SMI this cap is not relevant, but companies with a broad wage distribution must keep the base limits in mind when projecting payroll costs.

Special cases: part-time, temporary contracts and collective agreements

Always review your contract and the applicable collective agreement to confirm how the SMI update applies to your specific case.

Practical steps for employees

  1. Check your pay slip: confirm the gross monthly and annual amounts and the number of payments (12 or 14). The gross annual figure tied to the SMI in 14 payments should be 17,094 EUR.
  2. Review working hours: confirm whether your contract is full-time or part-time and whether the SMI is applied proportionally.
  3. Ask payroll for details: request an updated breakdown of Social Security bases and withholdings if your gross wage was adjusted.
  4. Use a payroll calculator for an indicative net figure: our salary calculator can simulate the effect of the SMI increase on net pay, but remember it is informative and must be compared with official AEAT withholding tables.

How to simulate your net salary (what to expect from a calculator)

A payroll calculator typically asks for gross salary, payment frequency (12 or 14 payments), social security contribution bases and personal tax data (marital status, dependents). Our simulation will:

Calculator limit: simulations are informative only. Official withholding for payroll is determined by the AEAT and the employer’s payroll department. Compare any simulation with official tables and your company’s payroll output.

Example (conceptual)

If your employer adjusts a monthly wage to match 1,221 EUR in 14 payments, your gross annual pay will be 17,094 EUR. From that gross amount, Social Security contributions (common contingencies, unemployment, training, etc.) and income tax withholdings will be deducted, resulting in your net pay. The exact net amount is individual and cannot be given here without personal data.

Conclusion and next steps

The 2026 SMI increase to 1,221 EUR/month in 14 payments (17,094 EUR/year) raises the legal wage floor and will affect gross wages and employer payroll costs where contracts reference the SMI. The precise impact on take-home pay depends on your personal tax situation and Social Security bases. Use official AEAT and Seguridad Social information and consult your payroll department to obtain exact figures.

Calculate an indicative net salary with our tool, but remember: the simulation is informative and must be checked against the AEAT withholding tables and your payroll department’s final figures.
