Mexico offers a deep talent pool and access to North American supply chains, but employment compliance is highly formal. The Federal Labor Law (LFT) protects employees, local payroll combines federal income-tax withholding with several social-security components, and state payroll taxes vary by location. A compliant operating model therefore begins before the first offer is issued.

For 2026, employers must distinguish the general and northern-border minimum-wage zones, update payroll for the new UMA, comply with the fully effective “Chair Law,” and prepare for the phased reduction of the constitutional workweek toward 40 hours. This guide gives HR, finance and legal teams a practical baseline; collective bargaining agreements, state rules and individual facts may require additional analysis.

1. Mexico Employment Compliance at a Glance in 2026

Employment rights generally cannot be waived. In disputes, substance prevails over labels: calling a worker an “independent contractor” does not prevent employee status where personal, subordinated services are performed for pay.

2. Three Employment and Payroll Changes Requiring Action in 2026

1. New wage floors and UMA. From 1 January, the daily minimum wage is MXN 315.04 in the general zone and MXN 440.87 in the Northern Border Free Zone. From 1 February, the daily UMA is MXN 117.31. Employers should update wage tables, integrated salary calculations, social-security limits and HR systems without using UMA as a substitute for a statutory minimum wage.

2. Workweek reform and implementation planning. A constitutional reform published on 3 March 2026 establishes a gradual path from the historic 48-hour ceiling to a 40-hour workweek by 2030. Employers should map shifts, collective terms and overtime exposure, then follow the operative transitional timetable and secondary rules rather than assuming an immediate universal 40-hour ceiling on publication.

3. Workplace seating and newer workforce models. The full “Ley Silla” requirements have applied since December 2025: appropriate seats with backrests must be available and employees cannot be required to stand throughout the working day where the law applies. Platform operators must also assess the special labor and IMSS framework for digital-platform workers and complete monthly social-security processes.

3. Mexico’s Employment Law and Regulatory Framework

The Constitution and the LFT form the core labor framework. The Social Security Law, INFONAVIT Law, Income Tax Law, National Workers’ Housing Fund rules, retirement-system rules, occupational health and safety standards, and data-protection legislation add parallel obligations. Federal labor courts hear individual and collective disputes after the mandatory pre-litigation conciliation process, subject to statutory exceptions.

The Ministry of Labor and Social Welfare (STPS), IMSS, INFONAVIT, SAT and the Federal Center for Labor Conciliation and Registration each supervise different parts of the lifecycle. State authorities also matter, particularly for local payroll tax and some labor jurisdiction questions.

Collective rights require special care. Employees may organize, bargain collectively and strike. A collective bargaining agreement, internal work regulations or established benefit practice can improve statutory rights and may become enforceable. Due diligence should therefore cover not only the offer and individual contract but also union status, applicable collective instruments and workplace policies.

4. Recruitment, Offers and Onboarding

Job advertising and selection criteria should be job-related and non-discriminatory. Employers should avoid decisions based on ethnic or national origin, sex, gender, age, disability, health, religion, migratory status, pregnancy, family responsibilities, marital status, sexual orientation or another protected ground. Pregnancy testing and certificates of non-pregnancy are prohibited as hiring or retention conditions.

A practical onboarding file normally includes the signed employment agreement, identity and address evidence, CURP, RFC/tax information, social-security number, bank details, emergency contact, role description, compensation approval, benefits enrollment, privacy notice acknowledgements and required immigration authorization. Collect only necessary personal data, issue the relevant privacy notice and restrict access.

Before work begins, register the employee with IMSS using the correct salary base. Late or understated enrollment can create assessments, surcharges, benefit-capital claims and labor evidence against the employer. Offers should be conditional where appropriate and must not promise a start date that precedes immigration permission.

5. Employment Contracts, Contract Types and Probation

Employment conditions should be documented in Spanish, even if a bilingual version is also used. The written agreement should identify the parties, nationality and addresses; contract duration; services and workplace; working time; salary, payment method and date; training; rest and vacation; designated beneficiaries; and other agreed conditions. If bilingual texts differ, specify the controlling version, but mandatory Mexican rights still prevail.

Indefinite employment is the default. Fixed-term or project contracts require a genuine statutory basis, such as the nature of the work, temporary replacement or a defined project. Repeated unsupported renewals can be treated as indefinite employment.

A probationary period may generally last up to 30 days and, for directors, managers, administrators or specialized technical/professional roles, up to 180 days. Initial training may generally last up to three months, or six months for qualifying senior or specialized roles. These arrangements must be written, provide salary and social security, cannot be successive or renewed, and count toward seniority if employment continues.

6. Wages, Minimum Wage and Gross-to-Net Payroll

Employers must apply the wage zone where the work is performed and any higher professional minimum wage for the occupation. The 2026 general minimum of MXN 315.04 per day has an official monthly reference of MXN 9,582.47; the northern-border daily minimum of MXN 440.87 has a monthly reference of MXN 13,409.80. Contractual salary, collective terms or market commitments may require more.

Gross-to-net payroll starts with cash salary and taxable benefits. The employer withholds monthly income tax (ISR) using SAT’s 2026 progressive tariff and applies the employment subsidy when legally available. It also withholds the employee share of IMSS and processes court-ordered, INFONAVIT credit or other lawful deductions. Net pay is the residual; deductions need a lawful basis and should appear on the payroll receipt.

Illustrative payroll flow only: an employee earning MXN 30,000 monthly is not taxed at one flat rate. Payroll identifies taxable income, applies the relevant lower-limit amount, fixed quota and marginal percentage in the current SAT table, subtracts applicable credits or subsidy, calculates employee IMSS under the statutory salary base, then issues a CFDI payroll receipt. Exact results depend on pay frequency, benefits, absences, variable pay and tax status.

Salary should be paid directly and on time, commonly weekly for manual work and no less frequently than every 15 days for other work under the LFT. Employers must issue correctly stamped digital payroll receipts and retain the supporting calculations.

7. Working Time, Overtime and Records

Historically, the LFT distinguishes day work (maximum eight hours per day), night work (seven hours) and mixed work (seven and a half hours), with one rest day after six days of work. The 2026 constitutional workweek reform introduces a phased route toward 40 hours by 2030. Until each transition rule becomes operative, employers must apply the ceiling legally in force for the relevant date and arrangement, together with any more favorable contract or collective agreement.

Under the established overtime framework, extraordinary work is limited and the first nine overtime hours in a week are generally paid at double the ordinary hourly wage; time beyond that threshold is generally paid at triple rate and increases compliance risk. The employee’s ordinary daily hours, rest periods, shift classification and overtime authorization should be recorded reliably.

Sunday work attracts a premium of at least 25% where Sunday is an ordinary workday. Work on a mandatory rest day normally requires the regular daily wage plus double pay for the service performed—triple pay in total. Shift redesign for the workweek transition must not reduce salary solely because statutory weekly hours fall.

8. Public Holidays, Annual Leave and Other Statutory Leave

The federal mandatory rest days occurring in 2026 are:

An election day designated by federal or local electoral law may also be mandatory. The six-year presidential transition holiday on 1 October does not occur in 2026. Holy Thursday and Good Friday are not federal mandatory rest days unless an employer policy, agreement or collective instrument grants them.

After one year, employees receive at least 12 paid vacation days. The entitlement rises by two days per year until reaching 20 days, then by two days for each subsequent five-year service block. Employees may take at least 12 continuous days, subject to their choice under the LFT, and receive a vacation premium of at least 25%.

Employees also receive an annual aguinaldo of at least 15 days’ salary, payable before 20 December, with a proportional amount for partial-year service. Statutory maternity leave is generally six weeks before and six weeks after birth, with up to four prenatal weeks transferable after medical authorization; adoption leave is six paid weeks. Fathers receive five paid working days for birth or adoption. IMSS eligibility and documentation affect benefit funding.

9. Employer Social Security, Mandatory Benefits and Tax

IMSS contributions are not a single flat percentage. The employer calculates occupational-risk insurance by class and claims experience, sickness and maternity components, disability and life insurance, childcare and social benefits, retirement, severance at advanced age and old age, plus employee shares where applicable. Several bases, thresholds and rates use the UMA; the contribution salary (SBC) generally cannot exceed 25 UMA—MXN 2,932.75 per day from 1 February 2026.

Employers also contribute 5% of the relevant salary base to INFONAVIT and process employee housing-loan deductions. Retirement contributions are integrated into the social-security collection process. State payroll tax is separate and its rate and tax base depend on the state where payroll is attributable.

The SBC is broader than base cash salary and generally integrates regular payments and benefits, subject to specific exclusions and limits. Payroll should reconcile employment contracts, attendance, variable compensation, CFDI receipts, IMSS filings, SUA/SIPARE payment records and accounting entries.

Employee profit sharing (PTU) is generally 10% of the employer’s taxable profit, allocated under statutory rules. Individual PTU is capped at the more favorable of three months’ salary or the average PTU received by that employee in the preceding three years. New companies and other categories may qualify for exemptions; directors and general managers are excluded, while other senior employees have special allocation rules. Corporate taxpayers commonly pay within 60 days after the annual return deadline.

10. Local Employees and Foreign Employees

Foreign nationals need immigration status authorizing remunerated activity; an employment agreement does not itself grant work permission. The sponsoring entity may need an employer registration certificate with the National Immigration Institute, and changes of employer or activity can require notice or a new authorization.

The LFT generally requires at least 90% of an employer’s workforce to be Mexican. Where suitable Mexican personnel are unavailable for a technical or professional specialty, foreign specialists may be employed temporarily, generally up to 10% of that specialty, with an obligation to train Mexican workers. Physicians working for enterprises must generally be Mexican. Directors, administrators and general managers are treated separately for the quota calculation.

Foreign employees remain entitled to Mexican labor protections. Cross-border payroll should separately assess tax residence, permanent-establishment, social-security and treaty issues. Paying from abroad does not remove a Mexican entity’s or economic employer’s local obligations.

11. Remote Work, Data Privacy and Record Retention

The statutory telework regime generally applies where more than 40% of services are performed at the employee’s home or another chosen location using information technology. The agreement and policy should cover equipment, inventory, work-related telecommunications and electricity costs, supervision, schedules, occupational safety, data security, reversibility and the right to disconnect. NOM-037-STPS-2023 adds workplace safety and health requirements for telework.

Mexico’s private-sector data-protection framework requires a privacy notice, lawful processing, proportionality, security measures and procedures for access, rectification, cancellation and objection rights. Sensitive data—health, biometrics and union information, for example—deserves enhanced controls. International transfers and HR-system access should be documented.

Employers should preserve contracts, payroll CFDIs, wage and attendance records, social-security notices, leave, benefits, disciplinary evidence and termination documents for the longest applicable labor, tax, social-security or litigation period. A practical retention schedule should account for interrupted limitation periods and active disputes rather than relying on one universal term.

12. Termination, Severance and Final Settlement

An employer may terminate without liability only for a statutory justified cause and should deliver a written notice describing the conduct and relevant dates directly to the employee or through the labor court within the legal process. A generic performance statement or undocumented loss of confidence is rarely enough.

For unjustified dismissal, an employee may generally claim reinstatement or constitutional indemnity equal to three months of integrated salary. Back pay may accrue for up to 12 months, followed by statutory interest if proceedings continue. Twenty days of salary per year of service applies in specified statutory circumstances and should not be automatically added to every dismissal estimate. A seniority premium of 12 days per year, subject to its statutory wage cap, may also apply.

Illustrative risk reserve: assume an employee has three years’ service and an integrated daily salary of MXN 1,200. The three-month component alone is approximately MXN 108,000 using 90 days. If a qualifying 20-days-per-year component applies, it would be MXN 72,000 before considering the seniority-premium cap, back pay, accrued benefits, taxes or litigation. This is not a universal severance formula.

On resignation or any separation, calculate earned salary, proportional aguinaldo, unused or proportional vacation, vacation premium, PTU if due and other earned benefits. A voluntary resignation normally attracts a seniority premium only after at least 15 years of service; dismissal rules differ. Obtain a signed settlement and use the competent conciliation authority where ratification materially improves enforceability.

13. Hiring Model: Entity, EOR or Payroll Outsourcing

Mexico prohibits subcontracting personnel as a general rule. Specialized services are permitted only when they are outside the beneficiary’s corporate purpose and predominant economic activity and the provider satisfies REPSE and other requirements. Labels do not cure prohibited labor supply. Before using an EOR or specialist provider, review the actual service model, corporate purposes, registration, intercompany instructions and employee supervision.
