TL;DR
An EOR in Mexico is the legal employer of your hires, it holds its own Mexican entity, assumes all liability under the Federal Labor Law (LFT), and runs payroll without you needing a local entity. Payroll outsourcing assumes you already have a Mexican entity and handles only the processing layer.
The 2021 Subcontracting Reform fundamentally changed the legal landscape. Generic personnel-leasing is prohibited. Any EOR providing specialized services must hold active REPSE registration with the STPS, verify this before signing anything.
REPSE enforcement is now coordinated across multiple federal agencies: the STPS, SAT, IMSS, and INFONAVIT cross-reference records in real time. Non-compliance with any one of them creates exposure across all four.
Mexico's mandatory payroll obligations are calculated on the Salario Base de Cotizacion (SBC), the daily base salary integrated with proportional statutory benefits. Getting the SBC calculation wrong means systematically underpaying IMSS, INFONAVIT, and SAR.
Aguinaldo (Christmas bonus, minimum 15 days of base salary) must be paid by December 20 each year. PTU (profit sharing, 10% of taxable profits) is due by May 30. Both are employer obligations under the LFT, not discretionary perks.
Mexico's EOR-to-entity break-even point occurs at approximately 10–15 employees, earlier than most other emerging markets because entity setup costs are relatively low ($2,000–$8,000).
The PTU advantage of EOR: PTU is calculated on the EOR entity's local taxable profit, not your company's global profit. For high-margin global businesses, this is a material financial advantage.
Mexico is a strategically significant nearshoring destination. The USMCA gives it structural advantages for US-facing operations. The talent market, technology, finance, professional services, is deep, bilingual, and competitive. The Federal Labor Law (LFT) is one of the most employee-protective legal frameworks in Latin America.
For international companies, the employment model they choose determines their legal liability, market entry speed, tax exposure, and compliance posture. The choice is not between EOR and payroll outsourcing as competing products. They serve different stages of market engagement and different entity structures. Getting the distinction wrong is expensive.
This guide covers the Mexico-specific mechanics of both models, the 2021 Subcontracting Reform and its November 2025 enforcement update, the mandatory payroll obligations that apply regardless of model, and the financial framework for deciding which structure makes sense for your current situation.
EOR vs payroll outsourcing: the fundamental difference
The difference between an employer of record and a payroll outsourcing provider in Mexico comes down to one question: who is the legal employer?
Employer of Record model
An EOR operates as the legal employer of your workforce in Mexico through its own pre-existing, registered Mexican entity. The EOR drafts and executes LFT-compliant employment contracts, registers employees with IMSS, calculates and runs monthly payroll, files all statutory returns, administers mandatory benefits including aguinaldo and PTU, and manages terminations with correct LFT severance calculations. Your company retains day-to-day management of the employees' work. The EOR holds all legal, administrative, and compliance responsibility under the LFT.
No local entity required. The EOR's existing corporate infrastructure covers everything. This bypasses Mexican corporate tax registration and significantly mitigates Permanent Establishment risk.
Payroll outsourcing model
Payroll outsourcing is an administrative processing service for companies that already own a registered Mexican entity. The client company remains the sole legal employer. The payroll vendor calculates gross-to-net payroll, generates CFDI 4.0 digital payslips, and prepares tax files. Nothing more. Labour disputes, compliance errors, IMSS contribution discrepancies, all of these land on the client's Mexican entity directly.
Payroll outsourcing is not available to companies without a Mexican entity. It is not a market entry tool. It is an administrative efficiency tool for companies already operating in Mexico at scale.
A foreign company directing the work of Mexican employees through a payroll outsourcing provider, without holding its own Mexican entity as the registered employer, is not operating under a legal employment arrangement. It is creating the same undocumented payment and contractor misclassification exposure that the 2021 Subcontracting Reform was specifically designed to eliminate. |
The REPSE framework and the 2021 Subcontracting Reform
The 2021 reform rewrote Mexico's subcontracting rules entirely. Generic personnel-leasing, where a company placed workers with a client without independent business operations, was prohibited. The replacement framework permits subcontracting only for "specialized services or execution of specialized works."
Any third-party provider that places personnel at a client's disposal must obtain certification through the Registro de Prestadoras de Servicios Especializados u Obras Especializadas (REPSE), overseen by the STPS. This registration is not a marketing claim. It is the legal foundation required to operate.
The critical compliance check: authorities verify REPSE compliance by comparing the provider's registered specialized activities against the corporate purpose in the client's bylaws. If the activities overlap, if the EOR is providing personnel to work on the client's core economic activity, the subcontracting arrangement is deemed illegal regardless of how the contract is drafted.
Verify REPSE status directly on the STPS public portal (repse.stps.gob.mx) before engaging any EOR provider in Mexico. The registration number must be active, not expired. An EOR that hesitates to provide this verification is telling you something important.
The REPSE registration must match the specialized services the EOR actually provides. An EOR registered for IT services that provides HR and payroll support to a financial services client may face a compliance challenge on scope grounds. Confirm that the EOR's registered specialization covers the nature of work your employees will be performing. |
The November 2025 enforcement update
On November 24, 2025, the STPS introduced a new inspection protocol that changed how subcontracting compliance is audited. The reform established standardized criteria for nationwide inspections and introduced real-time cross-agency data sharing.
When the STPS identifies an inconsistency during a subcontracting inspection, the data is shared automatically with the SAT, IMSS, and INFONAVIT to verify payroll tax filings, social security registrations, and corporate tax deductions. The audit methodology operates across three mechanisms: specific subcontracting inspections covering service agreements, payroll history, and training records; workplace interviews with employees to confirm that actual duties align with the specialized services contract; and multi-agency reconciliation correlating corporate bank ledgers, CFDI payslips, and REPSE registrations.
The consequences of non-compliance: denial of corporate tax deductions for service invoices, loss of VAT recovery rights, substantial administrative fines, and potential criminal prosecution for tax fraud. These are not theoretical consequences, they are the enforcement outcomes the November 2025 protocol was specifically designed to produce.
The Mexico payroll stack: SBC, IMSS, INFONAVIT, and SAR
Mexico's employer contribution framework is calculated on the Salario Base de Cotizacion (SBC), the daily base salary integrated with proportional statutory benefits including the aguinaldo, vacation premium, and other fixed compensation paid to the worker. The SBC is the base for IMSS, INFONAVIT, and SAR contributions. Getting the SBC calculation wrong means every downstream contribution is also wrong.
IMSS contributions
IMSS covers six branches: illness and maternity, disability and life, work risk, childcare, retirement, and INFONAVIT. Combined employer IMSS rate: approximately 20–25% of SBC, depending on the work risk classification (siniestralidad) of the industry. All IMSS contributions are capped at 25 UMAs per day, approximately MXN 87,000/month equivalent in 2026. For employees above this salary, contributions stop increasing. The effective IMSS rate decreases as salary rises above the cap.
INFONAVIT and SAR
INFONAVIT: employer contributes 5% of SBC, capped at 25 UMAs/day. Remitted bimonthly through the SIPARE portal. If an employee has an active INFONAVIT mortgage, the employer must withhold designated loan payments from net salary and remit directly to the housing authority, this is a mandatory withholding obligation, not a voluntary deduction. SAR retirement savings: approximately 2% of SBC through the RCV/AFORE retirement branch. These are accounting and financial services obligations that require exact calculation monthly.
ISN: the state payroll tax
ISN (Impuesto Sobre Nominas) is a state-level employer payroll tax that varies by location:
State / City | ISN Rate |
Mexico City (CDMX) | 3.0% |
Monterrey (Nuevo Leon) | 3.0% |
Guadalajara (Jalisco) | 2.5% |
Tijuana (Baja California) | 2.0% |
Queretaro | 3.0% |
Other states | 1.0–4.0% |
ISN is calculated on the total employer payroll, not on employee net salary. For a MXN 50,000/month gross employee in CDMX, ISN adds MXN 1,500/month to employer cost. Multi-city teams pay different ISN rates per employee location. An EOR with genuine Mexico operations files ISN per-state correctly for every employee.
Aguinaldo, PTU, and the annual compliance obligations
Aguinaldo (Christmas bonus)
Article 87 of the LFT mandates an annual Christmas bonus equal to at least 15 days of base salary for every employee. Payment deadline: December 20. The LFT makes no exception for companies that had a difficult year, it is an obligation regardless of profitability. A qualified EOR accrues the aguinaldo monthly (approximately 4.1% of annual base salary) and ensures payment on or before the December 20 deadline.
PTU (profit sharing)
Under the Mexican Constitution, companies are required to distribute 10% of their annual taxable profits to employees. PTU is due by May 30 each year. Each individual employee's PTU payout is capped at the greater of three months of the employee's salary or the average PTU of the prior three years.
The EOR advantage on PTU: under a compliant EOR model, employees are legally employed by the EOR's Mexican entity. Their PTU allocations are calculated on the EOR entity's local taxable profit, typically limited to its service margins. The client's global corporate profits are not directly exposed to PTU liability. For high-margin international businesses, this is a genuine financial advantage.
2023 vacation reform and prima vacacional
The 2023 reform increased statutory minimum paid vacation from 6 to 12 days in the first year, scaling up with tenure. Additionally, Article 80 of the LFT mandates a vacation premium (prima vacacional) of at least 25% of the base salary earned during the vacation period. These entitlements accrue from the first year of employment and must be correctly modelled in payroll from day one.
EOR vs payroll outsourcing: side-by-side comparison
Dimension | Employer of Record (EOR) | Payroll Outsourcing |
Legal employer | EOR (via its Mexican entity) | Client company (via its Mexican subsidiary) |
Entity required | No, EOR provides the legal framework | Yes, registered Mexican entity mandatory |
Labour and civil liability | Assumed by the EOR | Retained by client entity |
REPSE registration | Mandatory, EOR must hold active REPSE | Not applicable, client employs directly |
Onboarding timeline | 2–4 weeks from signed agreement | 3–6 months (entity incorporation first) |
PE risk mitigation | Significant, client has no Mexican entity | Retained by client entity |
Pricing model | Fixed monthly fee per employee | Variable, based on payroll volume or headcount |
Termination management | EOR handles LFT severance calculations | Client entity manages directly |
PTU exposure | Limited to EOR entity profit margins | Based on client entity taxable profit |
Which model fits your stage?
The decision is not about which model is "better." It is about which one matches your current entity status, headcount, and how long you plan to be in Mexico.
Use EOR if:
You want to hire your first employee in Mexico next month without a 3–6 month entity setup process.
You are testing the Mexico market with under 10 hires and want compliance without the overhead of a company registration process in a foreign jurisdiction.
You need to hire talent in multiple Mexican states and do not want to manage state-level ISN registrations in each location.
You want the PTU liability limited to the EOR entity's profit margins rather than your global corporate profit.
You are a high-growth company that wants to keep options open before committing to a permanent Mexican entity.
Use payroll outsourcing if:
You already have a registered Mexican entity and want to outsource the payroll processing mechanics.
You have an internal HR and legal team comfortable managing LFT compliance, IMSS registrations, and termination procedures.
You are operating at 10+ employees in Mexico and have validated that the market is a long-term commitment.
You want full ownership of the employment relationship and are prepared to absorb the compliance liability directly.
Mexico's break-even point between EOR and entity-owned payroll occurs at approximately 10–15 employees. Entity setup costs run $2,000–$8,000 total, relatively accessible compared to India ($8,000–$25,000), the Philippines ($5,000–$15,000), or Brazil ($15,000+). Below 10 employees or during market testing, EOR delivers better total value. Above 15 committed employees, entity evaluation is rational. |

Final Thoughts
Mexico's employer of record market is not complicated to navigate once you understand the two critical facts: the 2021 Subcontracting Reform changed what is legally permissible, and the November 2025 enforcement update means non-compliance is now identified in real time across four federal agencies simultaneously.
An EOR with active REPSE registration, its own Mexican entity, and genuine expertise in LFT compliance removes the compliance burden from your company entirely. Payroll outsourcing is the right tool once you have built that entity and want to outsource the processing mechanics. Knowing which stage you are at determines which model to choose.

Frequently Asked Questions
What is REPSE and why does it matter for an EOR in Mexico?
REPSE (Registro de Prestadoras de Servicios Especializados u Obras Especializadas) is the mandatory registration required under the 2021 Subcontracting Reform for any provider placing personnel at a client's disposal in Mexico. An EOR operating in Mexico must hold an active, verifiable REPSE registration. Without it, the EOR is operating outside the legal framework the reform created, and any client using that EOR faces denial of corporate tax deductions, loss of VAT recovery rights, and potential criminal prosecution for tax fraud. Check the STPS public portal directly before engaging any Mexico EOR provider.
Can a company hire remote workers in Mexico without a local entity?
Yes, through an EOR with active REPSE registration and a genuine Mexican corporate entity. The EOR is the registered employer. The client has no Mexican entity, no IMSS registration, no corporate tax presence. This mitigates Permanent Establishment risk and removes the 3–6 month incorporation timeline from the market entry path. What you cannot do is pay Mexican employees directly from abroad, through a payroll outsourcing arrangement, without your own Mexican entity, that structure is not legally available without local incorporation.
What is the Salario Base de Cotizacion and why does it matter?
The SBC (Salario Base de Cotizacion) is the daily base salary integrated with proportional statutory benefits, specifically the daily equivalents of the aguinaldo, vacation premium, and other fixed compensation. It is the base on which all IMSS, INFONAVIT, and SAR employer contributions are calculated. An employer that calculates contributions on base salary alone, without integrating the benefit aliquots, is systematically underpaying IMSS and INFONAVIT. The discrepancy is flagged during IMSS audits and creates retroactive contribution liability.
How does PTU work under an EOR arrangement in Mexico?
PTU (Participacion de los Trabajadores en las Utilidades) requires employers to distribute 10% of annual taxable profits to employees. Under an EOR model, employees are legally employed by the EOR's Mexican entity, not by the client. PTU is therefore calculated on the EOR entity's local taxable income, which is typically limited to its service margins. The client's global corporate profits are not directly exposed to PTU liability. For companies with strong global profitability, this is a genuine financial advantage of the EOR model over direct entity employment in Mexico.
What is the talent management strategy consideration when choosing between EOR and entity in Mexico?
A talent management strategy for Mexico requires understanding that the EOR model and the entity model produce different employee experiences. Under EOR, the employer of record is a different company from the one directing the work, this is transparent to the employee but requires clear communication in the onboarding process. Under entity, your company is the registered employer directly. At the early market entry stage, this distinction matters less than compliance precision. At scale, the entity model gives you more direct control over the employment brand in Mexico.
How are terminations handled under the LFT?
Mexico's LFT is highly protective of employees. Unilateral termination without a just cause under the LFT requires indemnizacion triple: 90 days of integrated salary, 20 days per year of service, and a seniority premium of 12 days per year (capped at two times the minimum wage daily rate per year). Pro-rated benefits, aguinaldo, vacation premium, and unused vacation, are added on top. A qualified EOR calculates these amounts accurately, manages the LFT-compliant termination documentation, and drafts finiquito agreements to close the employment relationship cleanly.
