Mexico is one of Latin America’s largest talent markets, and its payroll system is detailed, multi-layered, and strictly enforced. Foreign employers hiring in Mexico need to get familiar with social security contributions, mandatory bonuses, digital payroll receipts, and state-level taxes before they process their first payment. This guide walks through everything you need to run compliant payroll in Mexico in 2026.
How payroll is structured in mexico
Mexico’s federal labor law (Ley Federal del Trabajo) sets the baseline for wages, benefits, and employer obligations nationwide. Payroll compliance sits across several agencies: IMSS (Instituto Mexicano del Seguro Social) for social security, INFONAVIT for housing contributions, SAT (Servicio de Administración Tributaria) for income tax, and state revenue authorities for local payroll taxes.
Every employer must register with IMSS and obtain a registro patronal before processing payroll. This registration number is used for declaring and paying social security contributions and is central to all payroll administration.
Pay frequency
The standard pay frequency in Mexico is bi-weekly (quincenal), with payments made on the 15th and last day of each month. Some employers use a weekly schedule, but bi-weekly is the legal default and the most common structure in practice.
Salary base of contribution (sbc)
The Salario Base de Cotización (SBC) is the figure used to calculate IMSS and INFONAVIT contributions. It isn’t limited to base salary and must include regular bonuses, commissions, and other recurring payments. The SBC can’t fall below the minimum wage, and all contribution calculations flow from it.
Minimum wage in 2026
Mexico’s general minimum wage from January 1, 2026 is MXN 315.04 per day. Employers operating in the Northern Border Free Zone (Zona Libre de la Frontera Norte, ZLFN) must apply the higher rate of MXN 440.87 per day. These figures set the floor for the SBC.
Mandatory employer contributions
Mexico’s employer contribution burden is substantial, and it’s spread across several funds. All rates below apply to the SBC unless otherwise noted.
Imss (social security)
The employer’s total IMSS contribution typically falls between 15% and 25% of SBC, depending on the company’s risk classification and salary levels. The key components include:
| Component | Employer rate |
|---|---|
| Sickness and maternity (fixed quota) | Fixed quota per worker |
| Disability and life insurance | ~1.75% of SBC |
| Work risk insurance | 0.54%+ (varies by risk class) |
| Retirement (CyV) | 3.15%–7.513% (graduated, based on salary vs UMA) |
| Childcare (IMSS daycare) | 1% of SBC |
Employees also contribute to IMSS at approximately 1.65% of SBC.
Infonavit (housing fund)
Employers contribute 5% of each employee’s SBC to INFONAVIT, Mexico’s national housing fund. This is deposited into an individual housing subaccount and can be used by the employee toward a home purchase or left to accumulate.
SAR (retirement savings)
Employers deposit 6.5% of SBC into each employee’s AFORE retirement account as part of the Sistema de Ahorro para el Retiro. Employees contribute an additional 1.125% of SBC. These deposits are made alongside IMSS contributions and managed through the same declaration process.
State payroll tax (isn)
Each Mexican state levies its own payroll tax (Impuesto Sobre Nóminas, ISN) on employer wage bills. Rates typically range from 2% to 4%. Mexico City (CDMX) applies a 4% ISN rate in 2026. This is an employer-only obligation, paid monthly to the relevant state revenue authority.
Cfdi payroll receipts
Every pay period, you must issue a CFDI (Comprobante Fiscal Digital por Internet) digital payroll receipt to each employee. This is a legally required electronic document, generated through an authorized PAC (fiscal digital service provider) and stamped with a digital seal. Failing to issue CFDIs is a compliance violation with SAT and can result in penalties.
The CFDI must accurately reflect gross salary, all deductions, and net pay. It serves as the official payroll record for both tax and labor purposes.
Isr income tax withholding
Employers in Mexico are responsible for withholding income tax (ISR, or Impuesto Sobre la Renta) from employee salaries each pay period. The 2026 monthly tax brackets cover 11 tiers, with marginal rates ranging from 1.92% to 35% depending on the employee’s monthly income level. Employers apply the appropriate bracket, withhold the calculated amount, and remit it to SAT.
Each February, employers must issue every employee an annual tax statement (constancia de percepciones y retenciones) covering the prior year’s income and withholdings. This document is used by employees when filing their own annual tax returns.
Mandatory bonuses and benefits
Mexican labor law mandates several benefits that are paid or tracked through payroll. These aren’t optional: they’re statutory obligations, and most are linked to the employee’s daily wage.
Aguinaldo (christmas bonus)
Employers must pay a minimum of 15 days of salary as an aguinaldo by December 20 each year. Employees who haven’t completed a full year of service receive a proportional payment based on the months worked. The aguinaldo is one of Mexico’s most closely enforced payroll obligations.
Prima vacacional (vacation bonus)
When employees take their annual leave, they’re entitled to a vacation bonus (prima vacacional) of at least 25% of the wages corresponding to those leave days. It isn’t a separate year-end payment. It’s due at the time vacation is taken.
Annual salary review
Mexican law prohibits employers from reducing employee salaries. Wages are typically reviewed and adjusted upward annually, often aligned with changes to the minimum wage or inflation indicators. Even for commission-based roles, the base component can’t be cut.
Annual leave entitlements
Following the “Vacaciones Dignas” reform enacted in 2023, Mexico significantly increased statutory leave entitlements. The current schedule is:
| Years of service | Annual leave days |
|---|---|
| Year 1 | 12 days |
| Year 2 | 14 days |
| Year 3 | 16 days |
| Year 4 | 18 days |
| Years 5–9 | 20 days |
| Years 10–14 | 22 days |
| Every 5 years thereafter | +2 days |
These are minimum entitlements. You can offer more, but can’t go below these figures.
Public holidays and overtime
Mexico has 8 mandatory national public holidays per year. Employees who work on a public holiday must receive triple pay: their regular daily wage plus double that amount as a bonus. This applies to all employees regardless of payroll structure.
Working hours and the 2026 reform
The current standard working week in Mexico is 48 hours for day shifts, 45 hours for mixed shifts, and 42 hours for night shifts. A constitutional amendment passed in March 2026 reduces the standard to 40 hours per week for all shifts. The phased implementation begins in January 2027, so employers should plan payroll structures and staffing models accordingly ahead of that date.
Payroll deadlines and filing calendar
Staying on top of Mexico’s payroll calendar matters. Missed deadlines trigger fines and surcharges across multiple agencies.
| Obligation | Deadline |
|---|---|
| IMSS contributions | Declared and paid by the 17th of the following month |
| ISN (state payroll tax) | Paid by the 10th or 17th of the following month (state-dependent) |
| ISR withholding | Withheld monthly; annual reconciliation in February |
| CFDI receipts | Issued each pay period |
| Annual tax statement (constancia de percepciones) | Issued to each employee by February 28 |
How foreign companies can run payroll in mexico
Foreign companies without a Mexican legal entity can’t register directly with IMSS or process local payroll. The two main options are establishing a local entity or partnering with an Employer of Record (EOR).
Setting up a mexican entity
Registering a Sociedad Anónima de Capital Variable (SA de CV) or a SAPI de CV establishes a legal presence in Mexico and triggers full employer obligations: registro patronal registration, IMSS and INFONAVIT contributions, SAT registration, ISN filings, CFDI issuance, and all the payroll compliance covered in this guide. This route makes sense for companies with significant long-term headcount in Mexico.
Using an Employer of Record
For companies that want to hire in Mexico quickly without setting up a legal entity, an EOR becomes the legal employer in Mexico and takes on all employer obligations: IMSS registration, CFDI issuance, tax withholdings, mandatory bonus payments, and statutory reporting. The foreign company manages the employee’s day-to-day work, while the EOR handles local compliance. This is especially useful for smaller teams or initial market entry.
If you’re working with independent workers rather than employees, hiring through contractors is another option, though Mexico’s misclassification risks are real and the rules around contractor status should be reviewed carefully.
Common payroll pitfalls in mexico
A few areas where foreign employers frequently run into trouble in Mexico:
SBC miscalculation: Including only base salary in the SBC and omitting regular bonuses or commissions is one of the most common errors. Any fixed, recurring extra payment must be factored in.
Late aguinaldo: The December 20 deadline for the Christmas bonus is non-negotiable. Missing it exposes employers to labor complaints and potential penalties.
ISN oversight: State payroll taxes are easy to overlook when setting up payroll, particularly for remote teams spread across multiple states. Each state has its own rate, filing deadline, and revenue authority.
CFDI errors: A CFDI that doesn’t accurately reflect the employee’s earnings or deductions is invalid. This creates problems with SAT and can affect employees’ ability to file their own taxes correctly.
Vacation bonus timing: The prima vacacional is owed when vacation is taken, not at year-end. Employers who batch this payment incorrectly can end up in arrears.
