What Is Payroll in Mexico?
Payroll in Mexico refers to the comprehensive process of compensating employees while complying with Federal Labor Law, social security obligations through IMSS (Instituto Mexicano del Seguro Social), and tax withholding requirements under SAT (Servicio de Administración Tributaria). Employers must calculate gross wages, process mandatory benefits like aguinaldo and vacation bonuses, withhold ISR income tax, and issue CFDI payroll receipts.
The system integrates federal labor regulations with social security contributions, housing fund payments (INFONAVIT), and retirement savings (AFORE). Mexican payroll requires strict documentation, electronic invoicing compliance, and careful management of statutory benefits that significantly impact total employment costs beyond base salaries.
How Payroll Works in Mexico: A Step-by-Step Overview
Mexican payroll operates under strict legal frameworks requiring employers to register with IMSS, SAT, and INFONAVIT before hiring. Employers establish employment contracts specifying salary, benefits, and working conditions, then process payroll according to agreed payment frequencies while calculating mandatory benefits and statutory deductions.
Each pay period involves calculating gross salary including bonuses and overtime, determining employer contributions (IMSS, INFONAVIT, SAT), withholding employee portions and ISR tax, generating CFDI electronic payroll receipts, and distributing net pay while remitting taxes and social security contributions. The process requires precise calculation of integrated salary (salario integrado) used for benefit and contribution computations.
Payroll Cycle and Salary Payment Regulations in Mexico
Mexican Federal Labor Law permits weekly, bi-weekly, or monthly payment frequencies depending on employment terms and industry practices. Payment cycles are typically weekly for operational staff and bi-weekly or monthly for administrative and professional employees.
Employers must pay salaries on the agreed date in Mexican pesos, either through bank deposits or cash. Each payment requires a CFDI (Comprobante Fiscal Digital por Internet) electronic receipt issued through SAT-certified systems. Late payments trigger legal penalties and mandatory interest payments to employees, making punctual payroll processing critical for compliance.
Payroll Calculation Process: How Salaries Are Computed in Mexico
Salary calculation in Mexico begins with gross salary (salario ordinario) including base pay, commissions, and overtime at legally mandated rates (double time for first 9 hours beyond 48 weekly, triple time thereafter). Employers calculate integrated salary (salario integrado) by adding aguinaldo, vacation premium, and other benefits prorated daily.
ISR income tax is withheld based on SAT progressive tables considering employee deductions and tax credits. IMSS contributions (employee and employer portions) are calculated on integrated salary up to legal maximums. INFONAVIT housing contributions and other deductions are processed before determining net salary. All calculations must comply with SAT and IMSS formulas, with results documented in CFDI payroll receipts.
Salary Structure and Payroll Components in Mexico
Mexican salary structures incorporate base compensation plus mandatory benefits creating significant cost differences between gross salary and total employer costs. The integrated salary concept combines regular wages with prorated mandatory benefits for social security calculation purposes.
Total compensation packages include aguinaldo (Christmas bonus), vacation bonuses, profit sharing (PTU), and potentially food vouchers, transportation allowances, and savings fund contributions. Understanding the distinction between ordinary salary and integrated salary is essential for accurate payroll processing and cost planning.
What Are the Standard Earnings Components in Mexico?
Standard earnings in Mexican payroll include both regular compensation and mandatory benefit payments:
- Base Salary (Salario Base): Agreed regular wages per employment contract
- Overtime (Tiempo Extra): Double time for hours 49-57 weekly, triple time beyond
- Aguinaldo: Mandatory year-end bonus of minimum 15 days’ salary
- Vacation Premium: 25% bonus on vacation days (minimum 12 days after first year)
- Commissions and Bonuses: Performance-based variable compensation
- Food Vouchers (Vales de Despensa): Tax-advantaged benefit up to legal limits
- PTU (Profit Sharing): Mandatory 10% of company profits distributed to employees
Payroll Deductions in Mexico: What Gets Deducted from Employee Salaries?
Mexican payroll deductions include statutory withholdings and authorized voluntary deductions:
- ISR (Income Tax): Progressive federal income tax withheld using SAT tables
- IMSS Employee Portion: Social security contributions for health, disability, and life insurance
- INFONAVIT Loans: Housing loan repayments deducted from qualifying employees
- FONACOT Loans: Worker credit institute loan repayments
- Pension Fund (AFORE): Retirement savings contributions
- Union Dues: Trade union membership fees when applicable
- Other Authorized Deductions: Salary advances, garnishments, or voluntary savings
Understanding Salary Taxes and Statutory Obligations in Mexico
Mexican employers navigate complex statutory obligations including IMSS social security contributions, INFONAVIT housing fund payments, state payroll tax (ISN in some states), and federal ISR withholding. These obligations significantly exceed employee gross salary, typically adding 25-35% to total employment costs.
Compliance requires timely payment to multiple authorities, accurate CFDI generation, and detailed reporting through IDSE (IMSS) and SUA (Sistema Único de Autodeterminación) systems. Penalties for non-compliance include fines, interest charges, and potential criminal liability for severe violations.

Income Tax in Mexico: Rates, Withholding, and Filing
ISR (Impuesto Sobre la Renta) operates as Mexico’s progressive federal income tax with rates from 1.92% to 35% applied to monthly income brackets. Employers withhold ISR using SAT-published monthly tax tables, accounting for employment subsidies (subsidio al empleo) that reduce tax burden for lower earners.
The tax year runs January 1 to December 31, with employees filing annual returns by April 30 of the following year. Employers provide annual tax statements and must issue CFDI payroll receipts documenting all withholdings, ensuring employees can reconcile annual tax obligations.
How Does Income Tax Withholding Work in Payroll?
ISR withholding in Mexico requires employers to calculate tax using SAT monthly tables that consider gross taxable income minus authorized deductions like social security contributions. The calculation determines base tax, then applies employment subsidy credits (subsidio para el empleo) that reduce or eliminate tax for lower income ranges.
Withheld ISR must be paid to SAT by the 17th of the following month through electronic payment systems. Employers document withholdings in CFDI payroll receipts and provide annual statements to employees for tax return filing. Accurate withholding prevents employee tax liabilities and demonstrates compliance during SAT audits.
Tax Slabs, Rates, and Filing Requirements in Mexico
Mexican ISR applies progressive monthly tax rates to employment income:
| Monthly Income (MXN) | Tax Rate |
|---|---|
| $0.01 – $7,735.00 | 1.92% |
| $7,735.01 – $65,651.07 | 6.40% – 30.00% |
| $65,651.08 – $115,375.90 | 32.00% |
| $115,375.91 – $134,119.41 | 34.00% |
| $134,119.42+ | 35.00% |
Employers withhold monthly and remit by the 17th of the following month. Employees file annual returns by April 30, reconciling withheld tax with actual annual liability.
Social Security and Statutory Contributions in Mexico
IMSS (Mexican Social Security Institute) administers comprehensive social insurance covering healthcare, disability, life insurance, retirement, and childcare services. Employers and employees share contribution costs calculated on integrated salary, with employers bearing approximately 85% of total social security costs.
INFONAVIT manages housing fund contributions enabling employees to access mortgage financing. Combined with AFORE retirement savings and workers’ risk insurance, these statutory contributions create substantial employer obligations beyond base wages. Registration with IMSS is mandatory before hiring, with monthly payment deadlines strictly enforced through significant penalties for late or incorrect contributions.
Payroll Compliance: What Employers Must Follow in Mexico
Mexican payroll compliance demands strict adherence to Federal Labor Law, SAT tax regulations, IMSS social security rules, and CFDI electronic invoicing requirements. Non-compliance triggers severe penalties including fines up to 350 times minimum wage, interest charges, and potential criminal prosecution for serious violations.
Essential compliance requirements include:
- CFDI Generation: SAT-certified electronic payroll receipts for every payment
- IMSS Registration: Timely registration and monthly contribution payments
- Labor Law Adherence: Proper calculation of aguinaldo, vacation, profit sharing, and overtime
- Record Retention: Five-year retention of payroll records, contracts, and attendance documentation
- IDSE Reporting: Monthly reporting of salary modifications and workforce changes to IMSS
What Payroll Challenges Do Global Companies Face When Hiring in Mexico?
International companies entering Mexico face complexity in understanding integrated salary calculations that significantly impact social security costs beyond base wages. The CFDI electronic invoicing system requires SAT-certified software and specific technical implementations unfamiliar to foreign payroll systems.
Additional challenges include managing multiple authority relationships (SAT, IMSS, INFONAVIT), calculating mandatory benefits like aguinaldo and PTU profit sharing, navigating state-specific payroll taxes, understanding labor law termination requirements with constitutional protections, and implementing proper overtime calculations. Language barriers, different fiscal year considerations, and Mexico’s unique tax credit systems further complicate international payroll operations.
In-house Payroll vs Payroll Outsourcing vs Employer of Record (EOR): Which Is Right for You?
Companies operating in Mexico choose between managing payroll internally, outsourcing to local specialists (maquiladoras de nómina), or employing workers through EOR providers. In-house payroll requires significant investment in SAT-certified software, IMSS expertise, and continuous regulatory monitoring.
Outsourcing transfers processing complexity to Mexican specialists while maintaining legal employer status. EOR solutions provide full employment management where the EOR becomes the legal employer, handling all payroll, benefits, compliance, and labor law obligations. Selection depends on workforce size, market commitment, compliance risk tolerance, and internal capabilities for managing Mexican employment regulations.
How Does Payroll Outsourcing Work in Mexico?
Payroll outsourcing in Mexico involves engaging licensed maquiladoras de nómina to process payroll while your company remains the legal employer. The provider calculates salaries, generates CFDI receipts, processes IMSS and INFONAVIT contributions, withholds ISR, and manages statutory reporting.
You provide employee data, hours, and variable compensation information each period. The outsourcing partner ensures Federal Labor Law compliance, manages relationships with SAT and IMSS, and handles aguinaldo, vacation, and PTU calculations. This model reduces administrative complexity and compliance risk while preserving direct employment relationships, typically costing between $50-150 MXN per employee per payment period.
How Does Payroll Through Employer of Record (EOR) Work?
An Employer of Record in Mexico becomes the legal employer, assuming complete responsibility for employment contracts, payroll, IMSS registration, SAT compliance, and labor law obligations. The EOR manages recruitment, onboarding, employment documentation, all payroll processing, mandatory benefits, and termination procedures under Mexican law.
Your company directs daily work activities while the EOR handles employment relationships, mitigating legal risks associated with wrongful termination claims and labor law violations. This enables market entry without establishing a Mexican entity or navigating complex incorporation requirements. EOR services typically charge 18-30% of gross salary, providing comprehensive employment management and compliance assurance.
How Much Does Payroll Cost in Mexico?
Mexican payroll costs extend significantly beyond employee gross salaries due to substantial employer statutory contributions. Total employment costs typically reach 130-140% of base salary when including IMSS (20-25%), INFONAVIT (5%), SAR (2%), state payroll tax (2-3%), and mandatory benefits.
In-house payroll requires SAT-certified software ($200-1,000 USD monthly), specialized staff ($800-2,000 USD monthly salaries), and continuous training. Outsourced payroll services cost $50-150 MXN per employee per period plus setup fees. EOR solutions charge 18-30% of gross salary covering all employment obligations, compliance, and risk management. Additional costs include legal advisory services and periodic compliance audits.
