Hiring Mexican Contractors

How a compliant contractor engagement works in Mexico

1. Verify genuine independence before drafting anything. A defensible Mexican contractor sets their own schedule, works without day-to-day supervision, uses their own equipment and serves multiple clients. If the role you are filling requires fixed hours, your tools and your management, it is employment in substance and should be structured as employment.
2. Sign a services agreement, not an employment-shaped contract. The contract should describe deliverables and fees for professional services, not schedules, benefits or exclusivity. Terms that mirror employment, such as paid leave or fixed working hours, are evidence against you if the relationship is ever examined.
3. Require registered invoicing through SAT. Contractors must be registered with SAT, Mexico's tax authority, and issue CFDI electronic invoices carrying their RFC tax ID for every payment, generated through the government-approved system. Paying against compliant invoices is both a tax requirement and part of the evidence that this is a business relationship.
4. Pay against invoices and keep the file. Pay through traceable channels, whether local transfer, international wire or a contractor payment platform, and archive contracts, invoices and correspondence. If the engagement drifts toward employment over time, convert it deliberately rather than letting the file convict you.

Misclassification and the 2021 reform

Mexico's 2021 labour reform banned subcontracting personnel for a company's core business activities and restricted external staffing to genuinely specialised services, provided by firms registered on REPSE, the labour ministry's public registry of specialised service providers. Using an unregistered provider creates joint liability: if the vendor fails its workers, its social security obligations or its taxes, the client can be held responsible, and the related expenses can lose tax deductibility.

For individual contractors the risk is reclassification. A contractor found to be an employee in substance can trigger retroactive salaries, social security contributions, vacation pay and bonuses, plus fines, and in some fact patterns a permanent establishment question for the foreign client. The savings from misclassifying rarely survive contact with the remedy, which is why the classification test belongs at the start of the engagement, not after a dispute.

Contractor or EOR: choosing the right instrument

Use a contractor for genuinely independent, project-shaped work: defined deliverables, the contractor's own methods and tools, no exclusivity. Use an employer of record when what you actually want is a full-time team member in Mexico: the EOR's local entity employs the person, carries IMSS enrolment, statutory benefits and payroll withholding, and invoices you one monthly amount, salary plus fee.

The EOR route costs more each month than paying an invoice, and it buys the thing the contractor route cannot: a legal employer standing behind the statutory obligations, so classification risk stops being yours to argue. Vendors in this site's index publish per-employee monthly pricing for Mexico, verified against their own pages where published. Nothing here is legal or tax advice; classification turns on the facts of each engagement and the contract terms control.

Common questions

Can a US company pay a Mexican contractor directly?

Yes. The contractor should be registered with SAT, invoice each payment as a CFDI electronic invoice carrying their RFC tax ID, and be paid through a traceable channel such as bank transfer or a contractor payment platform. The client keeps the invoices as its compliance record.

What makes a Mexican contractor an employee in substance?

Control: fixed schedules, direct supervision, the client's equipment, one client and open-ended integration into the team. Those facts support reclassification with retroactive salaries, social security and benefits, regardless of what the contract calls the relationship.

What is REPSE and does it affect individual contractors?

REPSE is the labour ministry's registry of specialised service providers, created by the 2021 reform for firms supplying services with their own personnel. It targets staffing arrangements rather than genuine individual professionals, but using an unregistered provider firm creates joint liability for the client.

When should we switch a contractor to an EOR arrangement?

When the engagement has become a job: full-time hours, your direction, indefinite duration. An EOR employs the person compliantly in Mexico with statutory benefits and withholding, converting an argument you might lose into a monthly line item you can budget.
