SMI 2026 calculator: how your payslip looks if you earn the minimum wage in Madrid
What changed for the SMI in 2026 (quick facts)
- Tax year: 2026.
- Official SMI (2026): 1,221 EUR per month in a 14-payment structure; 17,094 EUR gross per year. (Source: BOE SMI 2026.)
- Social Security maximum contribution base (reference): 5,101.20 EUR/month.
- Employee MEI (mutual insurance contribution as provided): 0.15% (see employer/employee contribution rules applicable to your contract).
These values set the gross reference you must enter into any net-salary simulator for Spain. The rest of the payroll calculation depends on Social Security contribution bases and the IRPF withholding that applies to your personal situation.
How to simulate your net pay for Madrid (step-by-step)
- Open the calculator on calculadora-sueldo-neto.es and choose "Spain" as country and "Madrid" as autonomous community. The region matters because regional tax allowances and withholding rates can affect IRPF.
- Select payment frequency: 14 payments (prorated extra months) to match the official SMI 2026 format.
- Enter gross amounts using the SMI values: 1,221 EUR/month and 17,094 EUR/year.
- Fill in personal data that affect withholding: marital status, number of dependent children, other income, and whether you have tax residency or special circumstances. These determine the IRPF withholding rate.
- Leave employer-side figures as defaults unless you know the exact employer contributions or special mutual insurance arrangements; the calculator will show both employee and employer costs separately.
- Run the simulation. The output will show monthly and yearly net pay, Social Security employee contributions, and the IRPF withholding estimated for your profile.
Note: This tool performs an informative simulation. Always compare the estimated withholding with the official calculation from the Agencia Tributaria (AEAT) or the payroll issued by your employer.
What deductions appear on an SMI payslip (explained, Spain-focused)
- Social Security contributions: deducted from the employee’s gross pay and calculated on the contribution base. The SMI establishes the gross salary but the actual contribution base used by Social Security depends on how the contract and complements are structured. The official maximum contribution base for reference in 2026 is 5,101.20 EUR/month, but SMI wages are far below that cap.
- Mutual insurance (MEI): the provided reference is 0.15% for the indicated employee MEI contribution. Specific occupational mutuals or contractual agreements can alter this element.
- IRPF (withholding tax): depends on personal circumstances (marital status, dependents, other income, deductions) and regional specifics (Madrid). For many workers earning the SMI, the IRPF withholding may be very low or zero because annual taxable income is close to or below basic allowance thresholds; however, the final withholding must be determined case-by-case.
- Other withholdings: garnishments, voluntary contributions to pension plans, or other deductions appear only if applicable.
Example: what inputs to use (ready-to-copy)
- Gross monthly salary (14 pays): 1,221 EUR
- Gross annual salary: 17,094 EUR
- Region: Community of Madrid
- Payment frequency: 14 payments
- Personal situation: fill according to your real data (married/single, dependents, other income)
Enter these values into the calculator to obtain a net monthly amount and the breakdown of deductions. Remember that the calculator provides an informative estimate; the only binding amounts are those shown on your official payroll and those calculated by AEAT for tax withholdings.
Why the calculator result may differ from your payroll
- Employers sometimes include salary concepts (commissions, overtime, allowances) that change the contribution base.
- Company agreements, collective bargaining agreements or sectoral supplements can modify gross pay.
- Your actual IRPF withholding is set by the employer using AEAT tables and the personal information you provided on form 145. If that form is outdated or incomplete, withholding may be incorrect.
Practical tips to maximize net pay (within legal rules)
- Keep your personal data for tax withholding (form 145) updated with HR: marital status, dependents and other relevant information.
- Check whether any non-payable allowances or reimbursement items are being counted as salary; those can sometimes be excluded from the contribution base.
- If you think withholding is too high, consult AEAT or ask HR to review your withholding basis; formal changes must comply with tax rules.

Important limits and legal note (Spain-focused disclaimer)
This article provides an informative explanation and a guide to simulate net salary under the Salario Mínimo Interprofesional (SMI) in tax year 2026 for Spain. The SMI values above are taken from the BOE (official state bulletin). The calculator on this site offers an estimate; it does not replace the official withholding calculation performed by Agencia Tributaria (AEAT) or the formal payroll issued by your employer. For binding tax determinations, consult AEAT publications or a qualified tax advisor.
Calculator limit reminder: this is an informative simulation; official withholding must be compared with AEAT.

Frequently asked questions (short)
Is the SMI 1,221 EUR per month in all of Spain?
Yes: the official SMI for 2026 is 1,221 EUR/month in 14 payments nationwide (17,094 EUR/year) according to the BOE. Local cost-of-living does not change the statutory SMI amount, but other allowances and tax treatments can vary by region.
Will my IRPF be zero automatically if I earn the SMI?
Not automatically. Many workers at SMI levels have low or zero withholding, but the exact IRPF depends on individual circumstances. Use the calculator and verify with AEAT or your payroll department.
