What changed in 2026: the official SMI numbers

The Spanish Government published the SMI for 2026 in the BOE. For salaried workers the statutory SMI is set at:

• 1,221 EUR per month when paid in 14 payments (the common scheme in Spain), which equals
• 17,094 EUR per year gross.

These figures are the legal reference for minimum-pay contracts, salary clauses, and many collective agreements. They are the starting point for gross-to-net calculations but are not the only elements that determine take-home pay.

Official source: BOE (see the Sources section for the link to the legislative text).

How gross SMI translates to net pay: the main factors

There is no single net amount for everyone. Net pay depends on:

• Withholding for personal income tax (IRPF): the percentage applied by the employer to monthly pay depends on total expected income, personal and family situation (marital status, number of children or dependents), and other deductions or taxable benefits. Withholding is set using AEAT rules and tables.

• Social Security contributions (employee share): every employed worker contributes to general Social Security contingencies. The employer also contributes, but that does not reduce the gross salary shown in the contract. For 2026 you should check the Seguridad Social tables for exact percentages by contribution type; the maximum contribution base for some contingencies is 5,101.20 EUR/month (official reference provided).

• Specific deductions or items: meal allowances, transport, bonuses, or in-kind benefits can change the taxable base or be exempt under certain conditions.

Because withholding (IRPF) depends on personal circumstances and the AEAT withholding tables for 2026, our calculator provides an informative estimate; always compare the result with the official AEAT withholding calculation.

Social Security and employee contributions (2026 reference)

Two official numbers to keep in mind for payroll estimates:

• Maximum contribution base (reference): 5,101.20 EUR/month. This is the statutory cap used when calculating certain employer and employee contributions for higher earners; the SMI is well below this cap, but the maximum base matters for payroll administrators and collective agreements.

• Employee M.E.I. (work-related insurance) contribution: 0.15% (employee share value provided in the official facts). In practice, total Social Security contributions include several items (common contingencies, unemployment, vocational training, other specific contingencies) and splitting between employer and employee varies by item.

For the exact contribution percentages applicable to your contract and contingencies, consult the Seguridad Social website and the official contribution tables for 2026.

Practical examples (illustrative, not definitive)

Below are illustrative scenarios to show the kind of variation you can expect. Do not treat these figures as definitive withholding or final payroll amounts — they are simplified to explain mechanics.

• Single worker with no dependents paid SMI in 14 payments: gross 1,221 EUR/month. Social Security employee contributions will reduce gross to a lower taxable base; IRPF withholding may be low or zero depending on the overall annual income and personal situation.

• Worker with family responsibilities or additional deductions: the employer’s IRPF withholding can be lower because the AEAT calculation takes family credits and other allowances into account.

Remember: the precise IRPF withholding rate is determined using AEAT rules and is unique to each taxpayer.

How our SMI calculator helps

Our SMI calculator on calculadora-sueldo-neto.es lets you:

• Enter payment frequency (14 payments is standard for SMI) and gross monthly or annual pay.
• Input basic personal data that affects withholding (marital status, number of dependents, other income if any).
• See an indicative net pay after estimated Social Security employee contributions and an AEAT-based withholding estimate.

Call to action: Try the SMI calculator now to get a tailored simulation for your situation — remember: Informative simulation; official withholding must be compared with AEAT.

What the calculator does NOT do

• It does not replace AEAT’s official withholding calculations or a formal payroll slip prepared by your employer.
• It does not calculate employer-side costs (social charges paid by the company) in full detail unless explicitly selected.
• It does not provide legal or tax advice—only an informative estimate based on public rules and the data you enter.

How employers should apply the SMI in contracts and payroll

Employers must respect the SMI when setting gross salaries in contracts or collective bargaining. For payroll processing this implies:

• Ensuring the contractual annual gross does not fall below the legal SMI for the corresponding payment structure (12 vs 14 payments can change monthly amounts).
• Applying the correct Social Security contribution bases and rates for 2026 and the proper employee withholding according to AEAT’s instructions.

Payroll managers should consult BOE, Seguridad Social, and AEAT documentation to ensure compliance with 2026 rules.

Frequently asked questions

Is the SMI the same for all workers?

Yes: the SMI is the statutory minimum gross salary for full-time workers. Part-time work is pro-rated according to hours or the terms in the contract. Collective agreements can set higher minima for specific sectors.

Will I always pay IRPF if I earn the SMI?

Not necessarily. IRPF withholding depends on your total annual income, personal circumstances and applicable deductions. Many workers earning close to the SMI have low or zero monthly withholding, but the definitive liability is settled in the annual tax return if applicable.

Where can I check official tables for withholdings and contributions?

Consult AEAT (Agencia Tributaria) for IRPF withholding rules and tables, and Seguridad Social for contribution percentages and bases.
