Mexican Labor Law for U.S. Companies
Hiring in Mexico
What do U.S. companies get wrong about Mexican labor law?
Four assumptions imported from the U.S. cause most of the damage: that employment is at will, that work can be outsourced freely, that contractors stay contractors, and that benefits are what the offer letter says. In Mexico none of those hold — employment is protected by statute, subcontracting of core activities is prohibited, classification follows substance, and benefits including profit sharing accrue by law.
The practical consequence is that employment structure has to be designed before the first hire, not corrected afterward. Retrofitting a workforce built on U.S. assumptions is one of the most expensive corrections in a Mexican operation — and it usually surfaces at the worst possible moment, during a dispute, an audit, or a sale.
What usually drives exposure
Six assumptions that
do not travel south
At-will employment does not exist
Mexican labor law protects the employment relationship. Terminating without a legally recognized cause — and without the documentation to prove it — entitles the employee to statutory severance. U.S. managers routinely assume a notice period and a release will suffice.
Outsourcing of core activities is prohibited
The 2021 reform banned subcontracting personnel for a company’s core business. Only genuinely specialized services may be subcontracted, and the provider must be registered in REPSE. Structures that were standard before 2021 can now create joint liability.
Profit sharing is mandatory
Employees are entitled to a share of the employer’s taxable profits (PTU), subject to a statutory cap introduced with the reform. It is a payroll-driving obligation that must be modeled into the business case, not discovered in the first distribution year.
Misclassifying contractors
Whether someone is an employee is determined by the substance of the relationship — subordination, schedule, tools, direction — not by the contract label. A long-running "independent contractor" who works like an employee generates back social security, benefits, and severance exposure.
Union and collective bargaining obligations
The reform, reinforced by USMCA labor commitments, strengthened freedom of association and requires legitimate worker support for collective agreements. Protection contracts inherited from a prior operator or a seller are a liability rather than a shortcut.
Benefits are statutory, not discretionary
Vacation and vacation premium, Christmas bonus, seniority premium, and social security contributions are set by law and accrue regardless of what the offer letter says. Compensation designed on U.S. assumptions consistently understates true employment cost.
Hiring engineers in Mexico
Contractor, EOR,
or your own entity?
Most U.S. tech companies start nearshore hiring with contractors because it is fastest. The legal question is not what the contract says but what the relationship looks like — and who ends up paying severance and profit sharing if a labor court decides the contractor was an employee all along.
| Independent contractor | Employer of record (EOR) | Your own Mexican entity | |
|---|---|---|---|
| Who is the legal employer | Nobody on paper — until a labor court decides otherwise | The EOR’s Mexican entity | Your Mexican subsidiary |
| Misclassification exposure | High when the work looks like employment: set hours, your direction, exclusivity, your tools | Lower — but the 2021 reform bars subcontracting personnel for your core activity | Low, if contracts and payroll are set up correctly |
| Who pays severance | None for a genuine contractor; if reclassified, whoever is found to be the employer — possibly the U.S. company | The EOR, normally recharged to you under the service contract | Your subsidiary, per the Federal Labor Law |
| Profit sharing (PTU) | Not owed — unless reclassified | Owed by the EOR on its own profits | Owed by your subsidiary (exempt in its first year) |
| Permanent-establishment risk for the U.S. parent | Possible if people habitually act or sign for the parent | Reduced, not eliminated | Managed through the structure and intercompany agreements |
| Usually fits | Genuinely independent, project-based work | A small team, fast start, testing Mexico before committing | A long-term team doing core engineering work |

Where counsel matters
The employment
lifecycle
Design the structure
Decide who employs whom, whether any function can lawfully be subcontracted, and what the loaded cost of each role actually is under Mexican law.
Paper it correctly
Employment agreements, IP and confidentiality assignment, internal workplace regulations, and registration with social security and housing funds.
Keep the record
Performance documentation, policy acknowledgments, and payroll practices that make a later termination defensible rather than automatically costly.
Separate cleanly
Cause analysis, severance calculation, negotiated separation and ratification before the labor authority so the release actually holds.

Common questions
Hiring in Mexico,
answered
The questions U.S. HR and legal teams ask us most before building a workforce in Mexico. For your specific plan, a 30-minute call is the fastest path.
Not cleanly. Hiring people who work in Mexico generally requires a Mexican employer of record — either your own entity registered with the social security institute, or a third-party arrangement. Paying someone in Mexico from the U.S. payroll as a contractor is the most common shortcut and the most common source of exposure: it can create misclassification liability and, separately, permanent-establishment risk for the U.S. parent. If hiring is imminent, entity formation usually needs to start first.
REPSE is the public registry of specialized services providers created by the 2021 labor reform. A company that provides specialized services or works to another company must be registered in it, and the client must verify that registration. You need it if you provide such services to others; if you are the client, your obligation is to confirm your providers are registered and that what they provide is genuinely specialized rather than personnel for your core activity. Getting this wrong exposes the client to joint liability for the provider’s labor obligations.
It depends entirely on whether there is legally recognized cause and whether you can prove it. With proven cause, the obligation is limited to accrued amounts. Without it, the employee is entitled to statutory severance — commonly three months of salary plus twenty days per year of service, seniority premium where applicable, and accrued benefits, with back pay accruing while a dispute is pending. In practice most separations are negotiated and ratified before the labor authority, which is why the documentation built during employment matters more than the termination letter.
Employees are entitled to participate in the employer’s taxable profits, distributed annually. The 2021 reform introduced a cap: the individual entitlement is limited to the higher of three months of the employee’s salary or the average of what that employee received in the previous three years. Newly incorporated companies are exempt during their first year of operation. Because PTU is calculated on taxable profit, corporate and transfer-pricing structure directly affects it — which is one more reason the entity structure and the employment plan should be designed together.
They are treated very differently than in the U.S. Post-employment non-competes sit in tension with the constitutional freedom to work and are generally difficult to enforce as written; confidentiality and trade-secret protections are the more reliable instruments. Intellectual property created by employees does not automatically vest in the employer in the same way U.S. work-for-hire doctrine assumes, so express assignment language in the employment agreement is essential rather than optional.
A genuinely independent contractor is not owed statutory severance. The risk is reclassification: Mexican labor law presumes an employment relationship wherever someone provides personal, subordinated work, and courts look at substance — set hours, direction from your team, exclusivity, your equipment — not at the contract label. If a contractor is reclassified, statutory severance applies (commonly three months of salary plus twenty days per year of service, seniority premium where applicable and accrued benefits, with back pay possible during a dispute), and it is owed by whoever is found to be the employer, which can be the U.S. company itself. Under an employer of record, the EOR is the employer and pays severance, normally recharging the cost to the client.
Usually safer on misclassification, but not risk-free. Since the 2021 reform, subcontracting personnel to perform a company’s core activity is prohibited, and the client can be held jointly liable for a provider’s labor obligations — so an EOR arrangement for engineers doing your core product work needs to be structured and documented carefully. An EOR also reduces, but does not remove, permanent-establishment risk for the U.S. parent. It is a reasonable bridge for a small team; for a long-term engineering team, your own entity is usually the more stable structure.
