Mexican Labor Law, IMSS, and Infonavit: What Employers Need to Know

Mexico labor laws require employers to provide statutory benefits, register employees with IMSS, contribute to Infonavit, and comply with applicable workplace and employment regulations.

If you’re planning to hire software developers, accountants, customer support representatives, or other professionals in Mexico, understanding these obligations is an important first step.

And while Mexican employment regulations may differ from those in the United States or Canada, they become much easier to navigate once you understand which institutions oversee what.

This guide covers the essentials, from employee benefits to social security registration and compliance considerations for foreign companies.

 

Mexico Labor Laws: The Basics for Employers

The Federal Labor Law (Ley Federal del Trabajo, or LFT) is Mexico’s primary employment legislation. It establishes the rules governing employment contracts, working hours, mandatory benefits, employee protections, and termination procedures.

These rules apply to employment relationships in Mexico, including those involving foreign-owned businesses and international teams.

 

What Are Employers Required to Provide?

Here’s a quick overview of the main employment obligations:

 

 

These are legal minimums, not optional benefits. Employers can offer more generous compensation packages, but they cannot replace statutory entitlements with alternative benefits.

 

What About Working Hours in Mexico?

Mexico approved a gradual transition toward a 40-hour workweek in March 2026.

The reform establishes the following schedule:

The transition cannot be used to reduce employee salaries or benefits. Employers must also follow the applicable rules for daily shifts, rest periods, and overtime.

Mexico’s Workweek Reform Reflects a Broader Latin American Trend

Mexico isn’t the only Latin American country moving toward shorter working hours. Ecuador and Venezuela already have a statutory 40-hour workweek, while Chile is gradually reducing its limit from 44 hours in 2024 to 40 by 2028. Colombia is also transitioning toward a 42-hour workweek in 2026.

Mexico’s transition to 40 hours by 2030 reflects this broader regional shift toward shorter working weeks. For international employers managing teams across Latin America, these differences make it important to review local working-hour requirements when planning schedules and staffing.

 

What Is IMSS in Mexico? Employer Obligations Explained

IMSS (Instituto Mexicano del Seguro Social) is Mexico’s public social security institution. It provides eligible employees with access to healthcare, maternity benefits, disability protection, retirement-related benefits, and coverage for occupational risks.

Think of IMSS as a central part of Mexico’s employment protection system, rather than an optional insurance benefit.

 

What Are Employers Responsible For?

Companies employing workers covered by Mexico’s mandatory social security system generally have four responsibilities:

1. Employer registration: Register the employing entity with IMSS.
2. Employee enrollment: Register workers under their Social Security Numbers (NSS).
3. Contribution payments: Calculate and pay applicable employer contributions while withholding and remitting the employee portion.
4. Ongoing reporting: Notify IMSS of new hires, terminations, and salary changes.

 

Most employee affiliation notices must be submitted to IMSS within five business days, although certain circumstances have different requirements.

Beyond meeting deadlines, employers should pay attention to three areas:

• Accurate salary reporting: IMSS contributions are based on a legally defined salary that may include certain benefits and compensation beyond base pay.
• Updated employee records: Changes in compensation or integrated benefits may require adjustments to the information reported to IMSS.
• Compliance risks: Incorrect salary information, missed registrations, or late payments can result in additional contributions, penalties, and other liabilities.

 

The takeaway: Employment contracts, payroll records, and IMSS reporting should remain consistent, especially as your team in Mexico grows.

What Is Infonavit? Understanding Employer Housing Obligations

Infonavit (Instituto del Fondo Nacional de la Vivienda para los Trabajadores) is Mexico’s national workers’ housing fund, established to help employees access housing financing and build housing-related savings.

Unlike IMSS, which administers social security benefits, Infonavit focuses on workers’ housing rights.

 

How Does Infonavit Work for Employers?

Employers are generally required to contribute 5% of each employee’s applicable integrated daily salary to the worker’s housing fund.

These contributions are:

• Paid by the employer, not deducted from the employee’s salary.
• Submitted every two months.
• Required regardless of whether the employee currently has a housing loan.

Employees with an active Infonavit loan may also have mandatory payroll deductions that employers must withhold and remit according to the applicable notices.

This creates two different responsibilities: making employer housing contributions and administering employee loan repayments when applicable.

 

How Is Infonavit Different From IMSS?

Which Workplace Regulations Apply to Office-Based Teams in Mexico?

Not every workplace regulation applies in the same way to every business.

For example, a company employing software developers in an office has different occupational risks from a construction company or manufacturing facility.

However, office-based and remote employees are still protected by Mexico’s workplace health and safety regulations.

Three standards are worth understanding:

 

NOM-035: Psychosocial Risks in the Workplace

NOM-035 focuses on identifying and preventing psychosocial risk factors, including excessive workloads, workplace violence, and harmful working conditions.

It applies across industries, although the specific requirements depend partly on the number of employees at each workplace.

For office-based teams, the standard is particularly relevant to how workloads, working hours, and workplace relationships are managed.

 

NOM-037: Remote Work and Employee Safety

If your company employs remote professionals in Mexico, NOM-037 deserves attention.

Under Mexico’s teleworking framework, employees generally qualify as teleworkers when they perform more than 40% of their work away from the employer’s workplace using information and communication technologies.

When the rules apply, employers must address requirements involving suitable work equipment, health and safety conditions, training, and documentation.

The Federal Labor Law also establishes responsibilities concerning telework-related equipment and certain expenses, including telecommunications and electricity.

 

What About NOM-017-STPS-2024?

The updated NOM-017-STPS-2024 standard governs personal protective equipment (PPE), such as safety helmets, protective gloves, and specialized footwear.

For employees performing conventional administrative or computer-based work, PPE is generally not required.

However, the standard becomes relevant when workplace activities expose employees to risks requiring protective equipment.

The determining factor is the actual occupational risk, not simply whether the employer operates in a particular industry.

Compliance Considerations for Foreign Companies Hiring in Mexico

Understanding employee benefits is relatively straightforward. The bigger challenge for foreign companies is often determining who will be legally responsible for administering them.

For example, suppose a US-based company wants to establish a customer support team in Mexico.

The company may want to manage the employees’ schedules, performance, and daily responsibilities directly. However, employment contracts, payroll, social security registration, and local legal obligations must still be handled through a legally compliant structure.

 

Can Companies Outsource Employment Administration?

Yes, but the legal arrangement matters.

Mexico’s 2021 labor reform restricted personnel subcontracting under the Federal Labor Law. Specialized service arrangements may be permitted when they meet specific conditions, including REPSE registration where required.

An Employer of Record or shelter-company arrangement may help with employment administration, but the provider’s business model must comply with Mexican law.

Before choosing a partner, companies should clarify three questions:

1. Who legally employs the workers? Identify the Mexican employing entity and its responsibilities.
2. Who manages compliance? Confirm who handles employment agreements, IMSS, Infonavit, payroll, and applicable reporting.
3. Who manages daily operations? Establish how responsibilities are divided between the local employer and the foreign company directing the team’s work.

 

Frequently Asked Questions

What are the main Mexico labor laws foreign employers should know?

The Federal Labor Law establishes the main rules governing employment relationships, including contracts, working hours, benefits, and termination. Employers must also follow the Social Security Law, Infonavit requirements, and applicable workplace safety standards. Additional obligations may depend on the type of work, employment arrangement, and size of the operation.

Do employers have to register office employees with IMSS?

Yes. Office employees covered by Mexico’s mandatory social security system generally must be registered with IMSS, regardless of whether they work in accounting, software development, customer support, or other professional roles. Employers must also report relevant employment changes and meet applicable contribution requirements.

What happens if an employer fails to make Infonavit contributions?

Failure to pay required housing contributions can result in outstanding liabilities, surcharges, penalties, and collection actions. Employers are responsible for maintaining accurate employee salary information and submitting the corresponding payments. When workers have active housing loans, additional withholding and repayment obligations may also apply.

Does NOM-017-STPS-2024 apply to regular office employees?

The standard applies when workplace risks require personal protective equipment. Employees working exclusively in conventional office environments generally do not need specialized PPE. However, employers should assess actual occupational risks, particularly when employees enter operational areas or perform activities requiring protection.

What happens if a foreign company doesn’t comply with Mexican labor laws?

Depending on the violation, companies may face labor disputes, administrative fines, retroactive social security contributions, and other financial or legal consequences. The relevant authorities and liabilities depend on the employment structure and the obligations involved. Working with a local partner can support compliance, but responsibilities should be clearly established in advance.
