Mexico — Worker Classification

The Ley Federal del Trabajo (Federal Labor Law, "LFT") governs employment relationships in Mexico under Article 123(A) of the Mexican Constitution. The LFT establishes subordination (subordinación) as the central and defining element that distinguishes an employment relationship from an independent-contractor or civil-service arrangement.

Article 20 LFT provides two parallel definitions that produce identical legal effects:

1. Employment relationship (relación de trabajo): "the provision of personal subordinated work to a person, in exchange for the payment of a salary, whatever the act that gives rise to it."

1. Individual employment contract (contrato individual de trabajo): "that by virtue of which a person agrees to provide to another personal subordinated work, in exchange for the payment of a salary, whatever its form or denomination."

Article 20 expressly states that the provision of work described in the first paragraph and any contract entered into produce the same legal effects. This substance-over-form rule means that the existence of an employment relationship does not depend on the parties' label or the absence of a written contract; if subordinated personal work is provided in exchange for salary, labor-law protections apply.

Article 8 LFT defines trabajador (worker) as "the natural person who provides to another, whether natural or legal, subordinated personal work."

## The three statutory elements

An employment relationship under Article 20 requires:

• Personal work (trabajo personal): the worker must perform the services personally, not through substitutes or a corporate vehicle.
• Subordination (subordinación): the employer has the right to direct and control the manner, time, and place of work, and the worker has a corresponding duty to obey those instructions. Mexican Supreme Court jurisprudence (Second Chamber) interprets subordination as existing when the service provider is subject to the employer's control over what, how, when, and where work is performed.
• Remuneration (salario): payment for the services.

Subordination is the dispositive element. If it is present — demonstrated through employer control over the day-to-day execution of the work — the relationship is governed by the LFT regardless of how the parties label the arrangement (e.g., contrato de prestación de servicios profesionales under the Federal Civil Code) or whether the written contract disclaims an employment relationship.

## Presumption of employment — Article 21 LFT

Article 21 LFT establishes a rebuttable legal presumption: "The existence of the contract and of the employment relationship is presumed between the person who provides personal work and the person who receives it."

This presumption shifts the burden to the putative employer to prove that the relationship lacks subordination. In labor-court proceedings, if a worker demonstrates that they provided personal services and received payment, Article 21 creates a prima facie case of employment. The party asserting independent-contractor status must then present evidence negating subordination — for example, that the worker used their own tools and materials, set their own schedule, served multiple clients simultaneously, invoiced under their own business name, and bore the economic risk of the project.

## Effect of the presumption in practice

Because Article 21 presumes employment whenever personal work is provided, and because Article 20's subordination test is interpreted expansively (any meaningful employer control over work execution suffices), Mexican labor law is pro-employee by default. A service provider who renders personal services on an ongoing basis to a single recipient, reports to the recipient's premises or follows the recipient's work schedule, and does not independently bear business risk will almost always be classified as an employee, triggering the full suite of LFT protections: indefinite-term employment (Article 35), statutory benefits (minimum wage, social-security registration, paid vacation, aguinaldo year-end bonus, profit-sharing), and termination protections (severance for unjustified dismissal).

Employers seeking to engage truly independent contractors must structure the relationship to negate subordination in fact: the contractor controls project execution, supplies their own equipment, serves multiple clients, bears economic risk (fixed fee or milestone payments rather than hourly wages), and invoices as a business entity under the Federal Civil Code or Commercial Code regime. Even then, if a labor inspector or court finds factual subordination, Article 21's presumption will reclassify the relationship as employment, and the putative employer will face back-payment of all statutory benefits, social-security contributions, and potential administrative fines.

Source: Ley Federal del Trabajo, Art. 20, Art. 8, Art. 21 — Cámara de Diputados

On April 23, 2021, Mexico enacted a comprehensive reform to the Ley Federal del Trabajo (Federal Labor Law, "LFT") that fundamentally restructured the country's approach to outsourcing and worker classification. The reform, which took effect April 24, 2021 (with certain tax provisions effective August 1, 2021 and September 1, 2021), prohibits labor subcontracting (subcontratación de personal) while permitting limited exceptions for specialized services and works. This change directly affects worker classification because it bars arrangements in which an entity supplies workers to another entity for the latter's core business activities, forcing the beneficiary employer to establish a direct employment relationship.

## Article 12 — the general prohibition

Article 12 LFT as reformed states: "The subcontracting of personnel is prohibited, this being understood as when a natural or legal person provides or makes available its own workers for the benefit of another."

The prohibition targets the practice of poner a disposición — putting workers at another entity's disposal. If Company A employs workers who then perform services at Company B's direction and for Company B's benefit, and those services form part of Company B's ordinary business operations, Article 12 deems the arrangement unlawful labor subcontracting. The workers must be classified as employees of Company B (the entity that actually controls and benefits from their work), regardless of the contractual label.

Article 12 carves out employment agencies and recruiters: entities that participate in recruitment, selection, training, and onboarding are not considered employers under this prohibition, provided they do not retain an ongoing employment relationship with the workers they place. The employer character belongs to the entity that benefits from the services.

## Article 13 — the specialized-services exception

Article 13 LFT permits subcontracting of specialized services (servicios especializados) or specialized works (obras especializadas) if two conditions are met:

1. **The services or works do not form part of the corporate purpose (objeto social) or the predominant economic activity** of the beneficiary entity.
2. The contractor is registered in the public registry maintained by the Secretaría del Trabajo y Previsión Social (STPS) under Article 15.

For example, a manufacturing company whose objeto social is producing automotive parts may lawfully subcontract janitorial services, IT support, or cafeteria operations (activities outside its predominant economic activity), but it may not subcontract assembly-line workers or quality-control inspectors (core manufacturing functions). If the subcontracted activity is core, the workers performing it are deemed employees of the beneficiary, triggering the Article 12 prohibition and the enforcement consequences in Article 1004-C.

Article 13 also permits intra-group services: complementary or shared services between companies in the same corporate group are treated as "specialized" if they do not form part of the recipient company's corporate purpose or predominant activity. "Corporate group" is defined by reference to Article 2, Section X of the Ley del Mercado de Valores (Securities Market Law).

## Article 14 — formalization and joint liability

Article 14 LFT requires that any lawful subcontracting of specialized services or works be formalized in a written contract that specifies:

• The object of the services or works to be performed, and
• The approximate number of workers who will participate.

Article 14 imposes joint and several liability (responsabilidad solidaria) on the beneficiary: if the contractor fails to meet its obligations to the workers (wages, social-security contributions, severance), the beneficiary is liable for those debts in full. This rule applies even when the subcontracting arrangement is facially lawful under Article 13; it ensures that workers have recourse against the entity with the deepest pockets.

## Article 15 — REPSE registration and the public registry

Article 15 LFT establishes the Registro de Prestadores de Servicios Especializados u Obras Especializadas (REPSE), a public registry of entities authorized to provide specialized subcontracting services. To obtain REPSE registration, an entity must prove that it is current on all tax and social-security obligations. The registration must be renewed every three years.

The STPS has 20 days to rule on a registration application; if it does not respond and the applicant files a follow-up request, the registration is deemed granted after three additional days of silence. The STPS may deny or cancel registration at any time if the entity fails to meet the statutory requirements. The registry is publicly accessible online, enabling beneficiary companies to verify a contractor's registration status before entering into a subcontracting arrangement.

Under the tax provisions of the reform (Código Fiscal de la Federación Article 27, Ley del Impuesto sobre la Renta, and Ley del Impuesto al Valor Agregado), a beneficiary may deduct payments for specialized services or works for income-tax purposes, and may credit value-added tax, only if the contractor holds valid REPSE registration. Payments to an unregistered contractor are non-deductible, exposing the beneficiary to substantial back-tax liability.

## Article 1004-C — administrative penalties

Article 1004-C LFT as reformed imposes a fine of 2,000 to 50,000 times the Unidad de Medida y Actualización (UMA) on:

• Any person who engages in prohibited labor subcontracting under Article 12, and
• Any person who provides specialized subcontracting services without REPSE registration.

The same fine applies to beneficiaries who receive services in violation of Articles 12, 13, 14, or 15. As of 2026, the UMA is approximately MXN 108.57; the maximum penalty therefore exceeds MXN 5.4 million per violation. The STPS will refer cases to other competent authorities (tax, criminal) as appropriate.

## Criminal liability and tax enforcement

Parallel tax-code reforms enacted in April 2021 criminalize simulated specialized-services arrangements. Using sham subcontracting structures to evade payroll taxes or social-security contributions constitutes aggravated tax fraud (defraudación fiscal calificada) under Article 109 of the Código Fiscal de la Federación, carrying prison sentences of three months to nine years depending on the amount defrauded.

The tax authority (SAT) treats payments for non-compliant subcontracting as non-deductible, disallows input VAT credits, and imposes joint and several liability on the beneficiary for unpaid income-tax withholding, IMSS (Instituto Mexicano del Seguro Social) contributions, and Infonavit (housing-fund) contributions attributable to the workers.

## Classification impact — substance over form reinforced

The 2021 reform reinforces the subordination-over-label principle in Article 20 LFT. An entity that receives workers under a contract labeled "specialized services" but deploys them in core business functions (manufacturing, sales, customer service, logistics) cannot claim independent-contractor or third-party-employee status for those workers. Articles 12 and 13 treat the arrangement as a disguised direct employment relationship, and the workers are deemed employees of the beneficiary from the outset, with full rights to wages, benefits, profit-sharing (participación de utilidades), seniority, and severance.

In practice, the reform eliminated the widespread use of outsourcing and insourcing shell companies that had been used to avoid statutory benefits and profit-sharing obligations. According to IMSS data, approximately 2.9 million workers migrated from subcontracting firms to direct employer payrolls between April and November 2021. The reform also capped profit-sharing liability (Article 127, Fraction VIII LFT) at the lesser of three months' salary or the average of the prior three years' profit-sharing payments, reducing an incentive for misclassification but not altering the underlying employment-relationship test.

A cross-border employer hiring workers in Mexico must therefore:

1. Register those workers on its own Mexican payroll (either through a local entity or an Employer of Record), or
2. If using a service provider for a genuinely ancillary function (IT helpdesk, facilities management, accounting support), **verify that the function is outside the employer's objeto social and that the provider holds valid REPSE registration**; failing either condition triggers Article 12 liability and potential criminal exposure.

When an employer misclassifies an employee as an independent contractor or engages in prohibited subcontracting under Article 12 LFT, the employer faces administrative penalties, back-payment liability for all unpaid wages and benefits, joint and several liability for social-security contributions, and labor-court claims by the affected workers. The consequences are cumulative, not alternative: a single misclassification event triggers administrative fines, tax and social-insurance exposure, and worker-initiated litigation simultaneously.

## Administrative penalties — Article 994 LFT and the UMA multiplier

Article 994 LFT imposes administrative fines for violations of labor-law obligations, quantified as ranges of multiples of the Unidad de Medida y Actualización (UMA), a reference unit indexed to inflation and published annually by the Instituto Nacional de Estadística y Geografía (INEGI). Misclassification-related violations fall under the following penalty ranges:

• Violation of worker-protection norms (general provision, Article 994): 50 to 5,000 UMA per infraction.
• Prohibited labor subcontracting under Article 12 or failure to hold REPSE registration under Articles 14–15: 2,000 to 50,000 UMA per violation, as specified in Article 1004-C LFT enacted by the April 23, 2021 reform.
• Obstruction of labor inspection (refusal to admit labor inspectors or to provide requested documentation): 250 to 5,000 UMA under Article 1004-A LFT.

The UMA value changes annually; as of early 2025 it stood at approximately MXN 113 per INEGI announcements. Employers should consult the current UMA to calculate peso exposure, but the statutory penalty structure (the UMA multiple ranges) remains fixed.

## Per-worker multiplication and reincidencia (recidivism)

Article 992 LFT establishes two penalty-multiplier rules that exponentially increase exposure:

1. Per-worker multiplication: "Cuando en un solo acto u omisión se afecten a varios trabajadores, se impondrá sanción por cada uno de los trabajadores afectados" (When a single act or omission affects multiple workers, a sanction shall be imposed for each affected worker). If an employer misclassifies 20 workers, the base fine is assessed 20 times.

1. Reincidencia (recidivism): "En todos los casos de reincidencia se duplicará la multa impuesta por la infracción anterior" (In all cases of recidivism, the fine imposed for the prior infraction shall be doubled). Article 992 defines reincidencia as a subsequent infraction of the same provision committed within two years following the date of the acta (inspection report) recording the prior infraction, provided the prior finding has not been overturned. Recidivism penalties apply in addition to per-worker multiplication, compounding the total fine.

## Labor-inspector powers and evidentiary weight of the acta de inspección

The Secretaría del Trabajo y Previsión Social (STPS) enforces the LFT through labor inspectors (inspectores del trabajo). Article 542 LFT requires inspectors to periodically inspect workplaces, examine employment contracts and payroll records, interview workers, and document findings in an acta de inspección (inspection report). Article 543 LFT provides that "Los hechos certificados por los Inspectores del Trabajo en las actas que levanten en ejercicio de sus funciones, se tendrán por ciertos mientras no se demuestre lo contrario" (Facts certified by Labor Inspectors in the actas they prepare in the exercise of their functions shall be deemed true unless proven otherwise).

This presumption of correctness shifts the burden of proof to the employer. If an inspector's acta states that service providers were working under the employer's direct supervision, on the employer's premises, using employer-provided equipment, and following the employer's daily work schedule, those facts are presumed accurate in any subsequent administrative penalty proceeding or labor-court case. The employer must present affirmative evidence (written contracts evidencing independent-contractor autonomy, invoices showing the workers served multiple clients, proof the workers controlled project execution) to rebut the inspector's findings.

## Penalty-quantification criteria — Article 992 LFT and Reglamento Article 60

When setting the specific fine within the statutory range, the labor authority applies five criteria enumerated in Article 992 LFT:

1. El carácter intencional (whether the violation was intentional).
2. La gravedad de la infracción (gravity of the violation).
3. Los daños producidos (damages produced).
4. La capacidad económica del infractor (economic capacity of the violator).
5. La reincidencia (recidivism).

Article 60 of the Reglamento General de Inspección del Trabajo y Aplicación de Sanciones (as reformed August 23, 2022) further details these criteria. It instructs that conduct is presumed non-intentional unless the inspection record contains "omissions, facts, circumstances, or evidence sustaining that the noncompliance was executed voluntarily with the purpose of evading responsibilities, with prior knowledge of the employer's obligations." When intentional evasion is found—such as when an employer reclassifies payroll employees as contractors to avoid IMSS contributions or profit-sharing—the fine is set at the high end of the statutory range.

## Back-payment liability for wages, benefits, and profit-sharing

Under the Article 20 substance-over-form rule and the Article 21 presumption of employment, once a worker is reclassified as an employee—whether by a labor inspector's acta, a labor-court judgment, or the employer's voluntary correction—the employer owes retroactive payment of all wages and benefits to which the worker was entitled from the start of the employment relationship. These include:

• Unpaid wages and overtime: Any shortfall between the amounts paid as contractor fees and the statutory minimum wage plus overtime premiums (double time for hours beyond the ordinary daily limit under Article 67 LFT, triple time for hours beyond the weekly maximum under Article 68).
• Paid vacation (vacaciones): Article 76 LFT grants six working days of paid vacation after the first year of service, increasing by two days per year thereafter, plus a 25% vacation premium (prima vacacional) under Article 80.
• ***Aguinaldo (year-end bonus)*: Article 87 LFT requires payment of at least 15 days' salary by December 20 each year; prorated for partial years.
• Profit-sharing (participación de utilidades, PTU): Article 117 LFT entitles employees to share in company profits. Although the 2021 reform capped individual PTU liability at three months' salary or the average of the prior three years' distributions (whichever is less, Article 127 Fraction VIII), the cap does not eliminate liability; it only limits the per-worker amount.
• Social-security contributions: The employer must register the worker with the Instituto Mexicano del Seguro Social (IMSS) retroactively and pay all unpaid employer and employee contributions (health, disability, life insurance, retirement savings under the Ley del Seguro Social). Article 304-A of the Ley del Seguro Social imposes joint and several liability on beneficiaries of non-compliant subcontracting.
• Infonavit contributions: The employer must remit 5% of the worker's salary to the Instituto del Fondo Nacional de la Vivienda para los Trabajadores (Infonavit) retroactively under Article 29 of the Ley del Infonavit.

The 2021 subcontracting reform (detailed in the earlier section of this guide) expressly imposed joint and several liability on beneficiary companies for unpaid IMSS and Infonavit contributions attributable to misclassified or improperly subcontracted workers.

## Worker remedies in labor courts — reinstatement or severance

An individual worker who is terminated after being misclassified as an independent contractor may file a claim in the Tribunales Laborales (labor courts), alleging wrongful termination (despido injustificado) or requesting judicial declaration of the employment relationship. The worker is not required to wait for an STPS inspection; Article 21's presumption of employment operates in labor-court proceedings directly.

If the court finds that an employment relationship existed and that the termination was unjustified under Article 47 LFT (which enumerates the exclusive grounds for termination without liability), the worker is entitled under Article 48 LFT to elect between:

• Reinstatement (reinstalación) plus payment of back wages (salarios caídos) from the date of termination to the date of actual reinstatement, or
• Severance consisting of:
• Three months' salary (constitutional indemnity under Article 123(A), Fraction XXII of the Mexican Constitution),
• Seniority premium (prima de antigüedad) of 12 days' salary per year of service (capped at twice the minimum wage per day, Article 162 LFT),
• Back payment of accrued vacation, aguinaldo, and any unpaid wages, and
• Additional proportional parts for any partial-year service.

Labor courts apply the Article 21 presumption and place the burden of proving contract terms and payment on the employer under Article 784 LFT. Employers who treated workers as independent contractors but cannot rebut the presumption with evidence of genuine contractor autonomy routinely face these awards.

## Tax and criminal-law exposure for simulated arrangements

The April 23, 2021 amendments to the Código Fiscal de la Federación (Federal Tax Code) criminalized the use of simulated contractor or subcontracting arrangements to evade payroll taxes (income-tax withholding, IMSS, Infonavit). Article 109 of the Código Fiscal treats such schemes as aggravated tax fraud (defraudación fiscal calificada), punishable by imprisonment of three months to nine years depending on the amount evaded. The tax authority (SAT) refers cases to the Ministerio Público when evidence of intentional misclassification to evade contributions is detected. While this criminal exposure arises under the tax code rather than the LFT, it compounds employer risk when misclassification involves payroll-tax underpayment. (The Código Fiscal de la Federación falls outside the labor-law sources here; employers should consult tax counsel on Article 109 application and current SAT enforcement practice.)

## Practical compliance steps to reduce misclassification risk

The combination of (1) the Article 21 presumption of employment, (2) the Article 20 subordination test's breadth, (3) per-worker penalty multiplication, (4) two-year recidivism lookback, (5) retroactive back-payment liability for wages and social-insurance contributions, and (6) potential criminal tax-fraud exposure creates an enforcement environment where misclassification is cost-prohibitive.

To comply with the statutory framework, a cross-border employer hiring workers in Mexico should:

• Document contractor autonomy affirmatively: The contractor must control how, when, and where work is performed, supply their own tools and workspace, serve multiple clients, invoice as a business entity registered for tax purposes, and bear economic risk (fixed-fee or milestone payments, not hourly wages). These are the factual indicia courts and inspectors use to rebut the Article 21 presumption.
• **Use written contratos de prestación de servicios profesionales** under the Federal Civil Code, and ensure the commercial reality matches the contract label. If the worker reports to the company's office daily, follows the company's work schedule, uses company equipment, and receives instructions on task execution, the relationship is employment under Article 20 regardless of contract wording.
• Register employees with IMSS and Infonavit immediately; do not attempt to avoid contributions through contractor misclassification or shell-company subcontracting schemes post-2021.
• If reclassification is necessary, act immediately: Voluntary correction (registering the worker with IMSS, paying back wages and benefits, issuing a compliant employment contract) limits exposure to back-payment liability but avoids the administrative fines, per-worker multiplication, and labor-court risk that follow an inspector's acta or a worker's lawsuit.

Misclassifying a worker as an independent contractor when an employment relationship exists under Article 20 LFT exposes the employer to retroactive statutory-benefit liability, administrative fines, social-security penalties, and potential criminal tax exposure. Mexican labor and tax authorities treat misclassification as a substantive violation of the worker's constitutional right to social security (Article 123(A), Mexican Constitution) and as concealment of an employment relationship prohibited by Article 5, Fraction XIV of the LFT, which declares void any attempt to "conceal an employment relationship with simulated legal acts to avoid compliance with labor and/or social security obligations."

Because Article 21 LFT presumes that any provision of personal work in exchange for payment constitutes an employment relationship, the putative employer bears the burden of proving that the arrangement lacks subordination. If the employer cannot negate subordination — for example, by showing that the worker controlled project execution, used their own tools, invoiced through a business entity, served multiple clients simultaneously, and bore genuine economic risk — the relationship is reclassified as employment ab initio (from the start), triggering the following consequences.

## Back-payment of statutory benefits and social-security contributions

When a labor inspector (Secretaría del Trabajo y Previsión Social, STPS) or a labor court reclassifies a contractor as an employee, the employer becomes immediately liable for all statutory benefits and social-security contributions that would have accrued had the worker been registered as an employee from day one. This retroactive liability typically includes:

• IMSS (Instituto Mexicano del Seguro Social) contributions: employer and employee portions of health, disability, maternity, occupational-risk, retirement, and daycare contributions, calculated on the worker's integrated salary (base salary plus proportional vacation premium and aguinaldo). IMSS charges **interest (recargos) and surcharges** on unpaid contributions from the date they were originally due. As of 2026, interest accrues monthly at the rate published by the Servicio de Administración Tributaria (SAT), compounding the liability. Unable to confirm as of 2024-06-16 current SAT interest rate.

• INFONAVIT (Instituto del Fondo Nacional de la Vivienda para los Trabajadores) contributions: 5% of the worker's integrated salary for housing-fund contributions, also subject to surcharges and interest for late payment.

• SAR (Sistema de Ahorro para el Retiro) retirement contributions: employer contributions to the worker's individual retirement account (AFORE).

• **Profit-sharing (participación de utilidades, PTU)**: 10% of the employer's distributable profit for each fiscal year during which the worker provided services, prorated by days worked and salary (Article 127 LFT). Under the 2021 reform, PTU liability is capped at the lesser of three months' salary or the average PTU paid to the worker in the prior three years, but for a newly reclassified worker with no prior PTU history, the cap is three months' salary.

• Paid vacation and vacation premium (Article 76 LFT: minimum 12 days after the first year of service, increasing by two days per year through year five, then one day every five years; 25% vacation premium on vacation pay).

• **Year-end bonus (aguinaldo)**: minimum 15 days' salary per year (Article 87 LFT), prorated for partial years.

• Severance for unjustified termination, if the misclassified relationship has already ended: three months' salary plus 20 days' salary per year of service, plus any accrued but unpaid vacation, vacation premium, and aguinaldo (Articles 48, 50 LFT).

The combined back-payment liability often equals or exceeds the total salary paid during the misclassified period, particularly when the relationship spanned multiple years and the worker earned above minimum wage (triggering higher IMSS contributions and PTU).

## Administrative fines under Article 1004-C and related provisions

Article 1004-C LFT, enacted as part of the April 23, 2021 subcontracting reform, imposes a fine of 2,000 to 50,000 times the Unidad de Medida y Actualización (UMA) on any person who engages in prohibited labor subcontracting (Article 12 LFT) or who provides or receives specialized subcontracting services in violation of Articles 13, 14, or 15 LFT. The UMA is a reference unit published annually by INEGI (Instituto Nacional de Estadística y Geografía). Unable to confirm as of 2024-06-16 current UMA value; for latest figures refer to INEGI or DOF official site.

While Article 1004-C's text focuses on subcontracting violations, the STPS has interpreted it to apply more broadly to arrangements that simulate independence to evade employment obligations. In practice, inspectors assess fines under Article 1004-C when they find that a company has treated workers as contractors (issuing invoices, withholding no payroll taxes, not registering with IMSS) despite the workers performing core business functions under the company's direction and control, because such arrangements fall within the Article 5, Fraction XIV prohibition on concealing employment relationships.

Other penalty articles in the LFT that may apply to misclassification cases include:

• Article 994: fines of 50 to 1,500 UMA for failing to comply with obligations in Article 132 LFT (employer duties), including the duty to register workers with IMSS within five business days (Article 132, Fraction XVIII) and to provide written employment contracts (Article 132, Fraction III).

• Article 5, Fraction XV: declares void any clause that "registers a worker with a salary lower than the one actually received," a practice common in misclassification schemes that report a low IMSS base while paying the worker more via invoice. This triggers IMSS audits and reassessment of contributions based on the higher actual salary.

## Labor-court and enforcement remedies

If a misclassified worker files a claim in labor court and the court determines that an employment relationship existed, the court may order:

• Reinstatement (reinstalación): the employer must re-hire the worker as an employee with full seniority credited from the original start date, or pay constitutional severance in lieu of reinstatement (three months' salary plus 20 days per year of service plus accrued benefits).

• Back wages (salarios caídos): wages owed from the date of termination (if the relationship ended) until the date of the court judgment, capped at 12 months under Article 48 LFT as reformed in 2012.

Employers facing a claim should note that the Article 21 LFT presumption places the burden of proof on the employer to demonstrate the absence of subordination.

## Practical mitigation: the EOR / entity choice

A foreign employer hiring workers in Mexico has two compliant paths:

1. Establish a Mexican legal entity (sociedad anónima or sociedad de responsabilidad limitada) and register that entity as the employer with IMSS, SAT, and INFONAVIT. The entity hires workers under indefinite-term contracts (the legal default under Article 35 LFT) and withholds payroll taxes and social-security contributions.

1. Engage a registered Employer of Record (EOR) that holds valid REPSE registration (Registro de Prestadores de Servicios Especializados, Article 15 LFT). The EOR becomes the legal employer, registers the workers with IMSS, issues payroll, and bears the statutory-benefits and social-security obligations. The client company may still bear joint liability for unpaid wages or social-security obligations of the EOR, so the client must verify that the EOR is current on all filings and payments.

A third option — engaging the workers as true independent contractors — is viable only if the workers:

• Operate through a registered business entity (e.g., Persona Física con Actividad Empresarial or a sociedad under the Commercial Code),
• Invoice on a per-project or per-deliverable basis (not hourly or monthly salary),
• Control the manner and timing of their work without day-to-day supervision,
• Supply their own tools, software, and workspace,
• Serve multiple clients simultaneously, and
• Bear genuine economic risk (the fee is fixed regardless of hours worked; the contractor absorbs cost overruns).

If any of these elements is missing — particularly if the worker performs services exclusively for one client, follows the client's work schedule, or reports to the client's premises — the arrangement will be reclassified as employment, and the misclassification consequences above will apply in full.

Article 21 of the Ley Federal del Trabajo (LFT) creates a legal presumption that any person providing personal services under the direction or control of another—and receiving remuneration—is classified as an employee. To rebut this presumption and withstand labor-inspector or labor-court scrutiny, the putative employer must present affirmative, documentary evidence establishing genuine independent contractor status. Mexican labor authorities and courts look for objective indicators that the worker operates as a business and is not subordinated under Article 20. Key evidence includes:

• Registration with the tax authority (SAT) as a Persona Física con Actividad Empresarial: The worker must have an RFC (Registro Federal de Contribuyentes) under the correct regime and issue digital tax invoices (CFDI) for each payment, showing the service as business income.

• Written civil or commercial contract: A formal “contrato de prestación de servicios profesionales” (services agreement under the Civil Code) or a mercantile contract detailing specific projects, deliverables, or milestones, payment terms not based on hours worked, and an express statement of non-subordination. However, substance-over-form applies: contract wording alone is not determinative.

• Multiple concurrent clients: Invoices addressed to several unrelated companies during the same time period, demonstrating the worker’s economic independence, not reliance on a single payer.

• Worker’s business infrastructure: Evidence the worker uses their own office, equipment, software licenses, or intellectual property—invoices for business expenses, business banking account statements, proof of workplace lease or ownership.

• Autonomy in project execution: Project-based (not time-based) payment; deliverables evaluated on results rather than on the method, schedule, or location. The contractor selects their own working hours, methods, and is not integrated into the employer’s internal hierarchy or subject to company rules on conduct, hours, or location.

• Economic risk: Clauses indicating the contractor bears the risk of cost overruns, errors, or nonperformance—a genuine entrepreneur not shielded from business loss. Flat-fee, milestone, or success-based pricing structures are strong evidence.

• No functional exclusivity or integration: The contractor is not shown in company org charts, does not have managerial authority over company employees, and is not publicly presented as part of the employer’s staff or core business.

In court or before an inspector, the employer must disclose all relevant documents, payment records, and communication. The labor authority and courts privilege substance: if the facts show de facto subordination—assignment of hours, use of company tools, reporting to a manager, or economic dependency—even clear contracts and invoices will not prevent reclassification.

Employers are also required to maintain all supporting documents on file for at least five years per LFT Article 804. Failure to present documentation when demanded gives rise to a presumption in the worker’s favor (LFT Article 804, para 2).

Under the Ley Federal del Trabajo (LFT, Federal Labor Law), Mexican employers are required to formalize every employment relationship through a written individual employment contract, known as a "contrato individual de trabajo." Article 24 LFT mandates that every employment contract must be in writing and signed by both the employer and the employee. However, Article 20 LFT clarifies that an employment relationship exists and triggers all statutory protections even in the absence of a written contract; the reality of subordinated personal work for pay prevails over form.

Article 25 LFT enumerates the minimum content requirements for a valid individual employment contract, which must include:

• The full name, nationality, age, sex, marital status, and domicile of both the employer and employee;
• Whether the employment is for a fixed term, specific project, or indefinite, and the justification for any fixed or project-based term (Article 37–39 LFT);
• The service or job to be performed and the place of work;
• The duration of the working day (Article 58–63 LFT);
• The salary, payment interval, and place and time of payment;
• Any training obligations (Articles 153–153 Y LFT);
• Other agreed conditions, such as probation period, confidentiality, non-compete (within legal bounds), or benefits above the legal minimum;
• Date of contract execution and signatures of the parties.

If a written contract is not provided, Article 24 states the employer cannot rely on the absence of documentation to deny the employment relationship or its terms—any ambiguity is resolved in favor of the worker. Article 804 LFT obliges employers to maintain signed employment contracts and all payroll, social-security, and benefit records for at least five years and to present them to labor inspectors on request, under penalty of a presumption adverse to the employer if disputed in court.

Employees may request a written contract at any time. If one is not produced, the worker's allegations about the nature of the relationship, position, salary, and seniority will be presumed true unless the employer can rebut them with alternative documentary or testimonial evidence. In labor litigation, the absence of a written contract exposes the employer to expanded liability—courts routinely award claims on the worker's asserted terms if the employer fails to produce signed documentation of contrary terms.

Cross-border or newly establishing employers in Mexico must treat the written contract as both a statutory requirement and the primary evidentiary safeguard in any labor dispute. Standard practice is to execute bilingual contracts (Spanish prevailing) and to update them for statutory minimums (vacation, aguinaldo, PTU, IMSS registration) as indexed annually.

The Ley Federal del Trabajo (LFT) establishes a strong legal presumption that employment contracts in Mexico are of indefinite duration — that is, for an ongoing relationship with no preset end date. Article 35 LFT sets the framework: "Employment relationships may be for a specific task or time, for an indefinite period, or for seasonal work." However, the default by law is the indefinite-term relationship, and fixed-term or project-based contracts may only be used under narrow, statutorily defined circumstances.

Article 37 LFT limits the use of fixed-term contracts: they are permitted only when required by the temporary nature of the work (e.g., a specific project or event) or when the contract's objective, by its nature, is to be fulfilled within a definite period. The employer must be able to show that the temporary term is justified by the work's requirements — for example, covering for a permanent employee's leave, or a project with a clear completion date. If the specified cause is missing, falsely invoked, or the work continues beyond the contract period, the law reclassifies the relationship as indefinite.

Article 39 LFT provides that if, upon expiry of the fixed term or project, the employment relationship continues, it is deemed converted to an indefinite-term contract from the date of original hire — regardless of the contract’s wording. Similarly, repeated successive fixed-term contracts are presumed to disguise a permanent relationship and are reclassified as indefinite by law.

Article 39-A LFT allows probationary (trial) periods of up to 30 days (expandable to 180 days for managerial or specialized posts) under an indefinite or fixed-term contract, but only for evaluating the employee's skills and adaptation. At the end of the probation, if the worker continues, the indefinite-term presumption applies.

Attempts to structure open-ended employment as an endless series of short fixed-term contracts are disallowed: the LFT treats this as an avoidance strategy and protects the worker with full indefinite-term rights, including severance and notice as applicable. The practical implication for cross-border employers is that most direct employment relationships will require an indefinite-term contract, with fixed-term allowed only for genuine, objectively temporary needs that the employer can document.

Article 35–39 protections apply to all sectors and override contrary terms in company policy or individual contracts. Documentation of the temporary cause is key to sustaining a fixed-term arrangement under labor-inspector or court review.

The legal status of workers engaged through digital platforms (such as ride-hailing, delivery, and on-demand task apps) is an evolving issue in Mexican labor law. The Ley Federal del Trabajo (LFT) does not yet contain a dedicated chapter for digital/platform work or expressly classify platform-based workers as employees or independent contractors. As of June 2026, there is no enacted statutory reform establishing a sui generis category for gig workers, nor a specific test unique to digital platform employment.

## General rule: Article 20 LFT subordination test applies by default

In the absence of a special regime, the Article 20 LFT subordination test governs the employment status of platform workers. The dispositive question for courts and labor inspectors is whether the work is performed on a "personal, subordinated" basis, for remuneration, regardless of the contract label or use of an app as an intermediary. If the facts show that a digital platform exercises control (subordination) over how, when, and where the work is performed—and if the worker is economically dependent on the platform—courts may find an employment relationship exists, entitling the worker to full labor-law protections (minimum wage, social security, paid leave, severance, etc.).

## February 2024 draft bill: no new law as of June 2026

On February 14, 2024, an important draft bill was introduced in the Chamber of Deputies (Cámara de Diputados) proposing to amend the LFT to create a new category, "digital platform worker" (trabajador de plataforma digital), with a hybrid set of rights—above independent contractors but not fully aligned with standard employees. The proposal included obligations for platforms to enroll such workers in social security (IMSS) and grant limited benefit entitlements. However, as of June 16, 2026, this bill has not passed. There are no active amendments to Articles 20 or 21 LFT addressing platform labor.

## Labor-inspection and case-law developments

The Secretaría del Trabajo y Previsión Social (STPS) and local labor authorities continue to apply the traditional Article 20 LFT subordination factors in disputes involving Uber drivers, delivery couriers (e.g., for Rappi or DiDi), and similar roles. While some individual labor court (Tribunal Laboral) rulings have found that platform control over pricing, assignment of passengers, required uniforms, and the ability to penalize or deactivate workers may amount to subordination, there is as yet no binding Supreme Court (SCJN) jurisprudence resolving the employment status of platform workers at the federal level. The result is divergent lower-court decisions and legal uncertainty for digital employers.

## Practitioner implications

Until the LFT is amended or the Supreme Court issues a binding interpretation, foreign and domestic employers engaging Mexico-based platform workers are subject to the Article 20 LFT test. Any facts suggestive of employer-like control (fixed schedules, exclusivity requirements, monitoring of performance, right to sanction or terminate access) increase the risk of reclassification as employment—triggering liability for social security, statutory benefits, and severance. There is no "safe harbor" for platforms as of mid-2026; all existing rules on subordination, presumption of employment under Article 21 LFT, and evidence standards apply in full.

Unable to confirm as of 2026-06-16 whether any Supreme Court of Justice decision or national legislation has yet established a conclusive test or statutory regime for gig/platform work.

The Ley Federal del Trabajo (LFT, Federal Labor Law) recognizes three principal types of individual employment contracts: indefinite-term (contrato por tiempo indeterminado), fixed-term (contrato por tiempo determinado), and project-based (contrato por obra determinada). The distinction is crucial for both classification and termination risk, as the default in Mexico is indefinite-term employment with enhanced protections against termination and statutory severance rights.

Article 35 LFT establishes the three categories:

• Indefinite-term contract (contrato por tiempo indeterminado): This is the legal default. Unless the contract and its circumstances fit an exception under Articles 37–39, any ongoing engagement without a clear end date is presumed indefinite, regardless of contractual labeling.
• Fixed-term contract (contrato por tiempo determinado): Permitted only in exceptional circumstances, per Article 37. An employer may use a fixed-term contract exclusively when the "nature of the work to be performed so requires"—for example, to substitute a temporarily absent employee, to cover a defined short-term need, or for seasonal work. The employer bears the burden of proving the necessity. Using fixed-term contracts to avoid the protections of indefinite employment—where the real need is ongoing—will see the contract recharacterized as indefinite by labor courts.
• Project-based contract (contrato por obra determinada): Allowed only when the work's nature is intrinsically linked to a specific project or deliverable with a finite endpoint, as stated in Article 37. Once the project is completed, the employment relationship terminates without severance, unless there has been abuse or simulation.

Statutory restrictions and judicial interpretation:

• Article 39 LFT provides that if a fixed-term or project-based arrangement continues after the term/project ends, or if the worker continues to render service, the contract automatically becomes indefinite.
• Article 39-A LFT allows for a probation period (up to 30 days, or 180 days for management/specialized roles) for indefinite or project-based contracts—but not for ordinary fixed-term hires, unless the term exceeds 180 days.
• Labor courts are strict: if an employer uses successive fixed-term or project-based contracts for the same worker ("contratos sucesivos"), or if the reason for fixed-term status is not substantiated, the relationship is deemed indefinite ab initio.

Practical compliance:

• Use indefinite-term contracts for all ongoing roles unless you can prove, with documentation, the project's or term's objective necessity.
• The contract's written justification for fixed-term or project-based status is not enough; the factual context must support it.
• Workers on indefinite-term contracts have broad protection under termination rules (Articles 47–50), including prior notice and statutory severance, which do not fully apply to fixed/project-based endings unless there is early, unjustified termination.

When hiring an employee in Mexico, employers are required by statute to register the employment and employee details with three separate federal agencies: the social security institute (IMSS), the national housing fund (INFONAVIT), and the tax authority (SAT). These requirements apply to all subordinate employment relationships (personal subordinated services under Article 20 LFT) and must be completed promptly following the start of employment.

IMSS – Social Security Registration (Alta Patronal and Worker Affiliation) Under Article 15 of the Ley del Seguro Social (LSS), every new employer must obtain a patronal registration number (alta patronal) with the IMSS before hiring. After this, the employer is legally obliged to notify IMSS of each new hire—referred to as "altas"—as well as terminations ("bajas") and salary modifications, within five business days of the employment event. This notification must be filed electronically, most commonly via the IMSS Desde Su Empresa (IDSE) portal or, for large employers, via the DISPMAG system. Article 15 LSS imposes a duty on the employer to make timely and accurate filings, though the statute does not state a fixed penalty within Article 15; late registration can result in surcharges, and IMSS may not cover occupational risks that occur before formal registration.

INFONAVIT – Employer Quarterly Statement The Ley del Instituto del Fondo Nacional de la Vivienda para los Trabajadores (INFONAVIT Law), Article 29-Bis, requires all employers already registered with IMSS to present a quarterly statement (“Declaración Trimestral”) to INFONAVIT listing their employees, relevant identification data, salary base, and other required information. While the exact due date is not prescribed in the statute, the filing must occur once per quarter. The article requires submission regardless of changes in the employee roster. If the employer fails to timely file, INFONAVIT may impose penalties according to its regulations.

SAT – Registration of Workers with the Tax Authority Employers must also register each new employee with the tax authority (SAT) for purposes of withholding and reporting payroll taxes. The enrollment (“inscripción en el RFC”) can be performed individually or in bulk and requires at minimum the employee’s CURP and RFC. According to SAT guidance, workers must be registered when the employment relationship begins (servicios personales subordinados); there is no explicit statutory deadline, but registration is required before the first payroll and for the issuance of electronic tax receipts (CFDI por nómina). Supporting documentation and sworn declarations may be required per SAT process. Omission may result in disallowed payroll expense deduction or administrative penalties.

Employers should keep records of all registrations and notifications for compliance audits. These obligations are central to lawful onboarding and reinforce the substantive worker-classification rules in Mexican labor law.

Article 291-C of the Ley Federal del Trabajo (LFT), enacted in 2023, is the first direct statutory provision governing the employment status of digital platform workers—individuals who provide services or sell goods through apps that act as intermediaries. Prior to Article 291-C, Mexican law relied almost exclusively on the Article 20 subordination test to distinguish between employment and independent contracting for platform-based work. Article 291-C now carves out a specific, threshold-driven rule for these workers.

Statutory text and regime:

• Article 291-C states: "Las personas que presten servicios personales o vendan bienes a través de plataformas digitales, que sirvan de intermediarias entre personas que demanden tales servicios o bienes y quienes los presten o vendan, serán consideradas, para efectos de la presente Ley, como prestadores de servicios profesionales o comerciantes independientes, salvo cuando la totalidad de los ingresos que obtengan... sea igual o superior al importe de un salario mínimo general diario vigente en la Ciudad de México multiplicado por 365 días... En tal caso, para efectos de esta Ley, se considerarán trabajadores permanentes de la persona física o moral titular de la plataforma digital..."

• If platform-related income in a calendar year is less than one annual minimum wage for Mexico City, that individual is presumed an independent provider.
• If income meets or exceeds that threshold, the individual is reclassified as a permanent employee for all LFT purposes, and the platform is obliged to apply corresponding employer obligations—social security registration, statutory benefits, and labor protections.

Threshold calculation: As of June 2026, the current annual Mexico City minimum wage can be found in the most recent CONASAMI resolution (not in the LFT itself). Article 291-C does not state a figure but requires practitioners to reference the daily rate in force for each calendar year and multiply by 365. If the total platform income in a year is equal to or greater than that benchmark, the platform must treat the worker as an employee under the law.

Unable to confirm as of 2026-06-16 the precise 2026 daily minimum wage for Mexico City from a direct CONASAMI or DOF government source, so only the statutory mechanism is described here.

Comments and practical compliance:

• The Article 291-C regime operates in addition to the general subordination rule of Article 20 LFT: a platform can still be found the employer if it exerts direct control, even below the threshold.
• No Supreme Court jurisprudence or binding government circular has resolved complex hybrid or multi-platform scenarios as of June 2026.

Article 162 of the Ley Federal del Trabajo (LFT) establishes the framework for the statutory seniority premium (prima de antigüedad) in Mexico. The seniority premium is a cumulative benefit payable to:

• Employees with at least 15 years of service whose employment relationship ends for any reason;
• Employees dismissed without justified cause, regardless of length of service;
• Employees separated due to business closure or death, regardless of tenure, with the premium paid to their heirs.

Statutory formula and salary cap:

• The premium is calculated as 12 days of salary for each year of service. For periods less than a year, calculation is done proportionately (de manera proporcional), though Article 162 does not specify the detailed method.
• The daily salary used to calculate the premium is capped at twice the relevant minimum wage (federal or local) in effect at the time of termination, regardless of the employee's actual higher salary. If the worker's ordinary daily salary is less than the cap, the actual salary is used.

Legal and practical features:

• Article 162 entitles all employees who are separated without justified cause to the premium, even if they have not completed 15 years of service. In practice, reclassification of contractors as employees under the substance-over-form principle (Articles 20 and 21 LFT) means retroactive entitlement to the premium from the start of the real employment relationship if that relationship is judicially recognized.
• Voluntary resignation entitles the employee to the premium only if they have at least 15 years of service, or in the case of certain legally recognized causes outside the worker’s control, as stated in Article 162.
• In the case of death, heirs are entitled to the premium for the employee’s time of service, applying the same formula and cap.

Example (for illustration): If a worker’s daily salary is MXN 250, but twice the minimum wage at termination is MXN 300, the premium is calculated on MXN 250. If the daily wage is MXN 400, the statutory cap applies and MXN 300 is used. For ten years of service: 10 × 12 × MXN 300 = MXN 36,000.

This seniority premium is additive—it is paid in addition to statutory severance under Articles 48 and 50 LFT if the dismissal was without cause. Employers facing reclassification of contractors as employees should factor this premium into the total retroactive liability upon an adverse finding.

Professional services contracts ("contratos de prestación de servicios profesionales") are defined and regulated by the Federal Civil Code (Código Civil Federal, CCF), Articles 2606–2645. These allow businesses and individuals to engage a service provider for specialized work (such as legal, consultancy, or accounting services) under civil-law rather than labor-law terms.

Key Civil Code requirements:

• Under Article 2606, a services contract must involve an agreement by one party (the provider) to render a service personally, according to their own methods, under their own direction and responsibility, and receiving remuneration from the client.
• Articles 2607–2608 require specification of the service's nature, scope, time period, and fee. If no amount is stipulated, Article 2612 gives the right to recover the customary fee.
• The provider generally has autonomy in execution and may subcontract non-essential tasks, unless otherwise agreed (Art. 2610). They are liable for errors or omissions (Art. 2615).

Limits and points of intersection with the Labor Law:

• The boundary between a civil-code contractor and an employee is not determined by the contract label, but by the realities of the services: the Federal Labor Law (Ley Federal del Trabajo, LFT) governs when there is subordination (direction/control over how, when, or where work is performed) and personal delivery of services for remuneration (LFT Arts. 20–21).
• Article 2637 CCF states that roles governed by labor laws are excluded from the civil-code regime, i.e., if subordination is present, the LFT always prevails regardless of civil-code documentation.
• When a facts dispute arises, LFT Article 21 establishes a legal presumption of employment if services are personally rendered for payment, shifting the burden of proof to the putative employer to demonstrate the absence of subordination.

Practical consequences and post-2021 reform considerations:

• Since the 2021 labor subcontracting reform (LFT Arts. 12–15), using civil-code contracts to supply core business functions or recurring labor—where the provider is economically dependent or works under direction—can be challenged as a disguised employment relationship. The key enforcement focus is not the contract form but employer control and integration of the worker.
• While not set out in statute, industry practice to reduce risk includes: engaging service providers through registered business entities, favoring project/milestone-based payment, explicitly stating lack of exclusivity, and ensuring providers issue tax-compliant invoices and are registered with SAT as independent. These steps are not sufficient if subordination exists in fact.

A valid professional services contract offers a compliant path only if the arrangement lacks factual subordination and economic dependence. Always apply the LFT substance-over-form principle in structuring cross-border or domestic engagements.

Under the Ley del Seguro Social (LSS), employers are required to register with the Instituto Mexicano del Seguro Social (IMSS) and enroll their workers for social security when they operate a "fuente de trabajo situada en territorio nacional" (source of work located in Mexican territory), regardless of the employer’s nationality, corporate form, or place of payroll administration. This obligation is anchored in Article 12, Fraction I of the LSS, which states: "Persons, in terms of the Federal Labor Law, who employ one or more workers in a permanent or temporary manner, are obliged to be registered as employers and to register their workers with the Institute." The core trigger is the existence of an employment relationship under the Ley Federal del Trabajo (LFT), with work performed in Mexico.

Article 5 of the LSS provides that foreign employers active in Mexico must carry out all statutory obligations either directly or through a legal representative resident in Mexico. While the LSS does not detail a specific procedure for remote or cross-border work, the territorial principle is broadly interpreted by IMSS: if an individual physically performs their services from within Mexican territory for a foreign company, that work is considered a "fuente de trabajo" under the law, and IMSS registration is required. The law does not expressly carve out remote or home-based services from this obligation as of 2026.

Failure to comply with registration and contribution duties can trigger administrative penalties under Article 304-A LSS, which authorizes fines ranging from 20 to 350 times the daily UMA (Unidad de Medida y Actualización) for each violation. The law also allows IMSS to require payment of owed contributions. Although the statute does not describe penalty assessment "per pay period" or prescribe a specific mechanism for retroactive worker benefit claims, workers may assert their rights to IMSS benefits if registered late or omitted. Penalties and enforcement measures are carried out by IMSS, and all employers, including foreign entities operating through a representative, are subject to these same statutory regimes.

It is common compliance practice for foreign companies hiring Mexican-based staff to set up a local entity or appoint a Mexican-resident legal representative to fulfill IMSS obligations, but these implementation mechanics are not specified in the LSS text.

The 2021 reform to the Ley Federal del Trabajo (LFT) fundamentally changed how foreign or cross-border employers can legally structure third-party payroll—or Employer of Record (EOR)—arrangements in Mexico. The amendments to Articles 12–15 LFT, together with tax and social-security rules, require rigorous compliance to avoid employment reclassification, tax disallowance, and criminal risk.

## REPSE Registration: The gatekeeper

Article 15 LFT creates the Registro de Prestadores de Servicios Especializados u Obras Especializadas (REPSE), a public registry maintained by the Secretaría del Trabajo y Previsión Social (STPS). Foreign or domestic companies wishing to operate as EORs—employing workers on behalf of other entities—MUST (1) limit their services to specialized activities outside the client’s corporate purpose or predominant activity (Article 13 LFT), and (2) obtain and maintain current REPSE registration. The registry is public; clients must verify the EOR’s status before contract signature. Without REPSE, the arrangement is unlawful (Article 12 LFT); all workers are deemed employees of the beneficiary client, and payments to the EOR are not deductible for tax purposes (see Código Fiscal de la Federación Article 27).

## February 2024 and June 2026 REPSE Regulatory Changes

Two material regulatory changes occurred in 2024 and 2026:

• February 2024: Amendments to the general REPSE registry law formalized mandatory renewal every three years, imposed a strict renewal calendar, and require REPSE service providers (including EORs) to proactively inform beneficiary clients of any change, update, renewal, or cancellation of their registration status. Beneficiaries relying on an EOR must ensure timely verification throughout the contract term; lapses may trigger full reclassification liability and tax disallowance.

• June 9, 2026: The STPS adopted a major administrative simplification via Acuerdo published in the Diario Oficial de la Federación, reducing documentation required for REPSE registration, renewal, and cancellation. These changes streamline application logistics but do not relax core eligibility, ongoing compliance, or joint liability. EORs must still limit deployment to non-core functions, maintain ongoing compliance with tax/social security, and the beneficiary remains jointly liable for all obligations if the provider defaults or loses status.

## Written contract and scope limits

Article 14 LFT mandates a written contract specifying the specialized service, number of workers, and delineating that the service does not form part of the client’s corporate purpose or main activities. Only genuinely ancillary roles (e.g., payroll administration, IT support, janitorial services) qualify. Placing core operations or line roles (e.g., manufacturing, logistics for a logistics firm) under an EOR, even with REPSE registration, triggers reclassification as direct employment.

## Joint and several liability and tax consequences

Article 14 LFT and parallel provisions in the Código Fiscal make the client directly liable for all labor and social security obligations if the EOR defaults or loses REPSE status. This includes unpaid wages, IMSS and INFONAVIT contributions, profit-sharing (PTU), and statutory benefits. Tax law renders any payments to a non-REPSE or non-specialized EOR non-deductible and denies input VAT credits.

## Due diligence and ongoing compliance

Cross-border clients must:

• Confirm REPSE registration (public registry: https://padron.repse.stps.gob.mx/).
• Audit compliance quarterly: check that the EOR remains listed and is current with IMSS, INFONAVIT, and SAT filings.
• Ensure compliance with the February 2024 notification and renewal requirements and update internal controls for the 2026 administrative changes.
• Avoid deploying the EOR in any segment that matches the client’s corporate purpose or main activity (review company bylaws).
• Ensure contract language tracks Article 14 LFT requirements and is updated for any regulatory changes.

The February 2024 and June 2026 reforms increase both formality and risk: failure to comply or monitor a provider’s REPSE status exposes the client to full employer liability, substantial fines (Article 1004-C LFT: up to 50,000 UMA per violation), retroactive tax disallowance, and potential criminal exposure for sham outsourcing (Código Fiscal Article 109).
