Searching for a Mexico PEO usually means one of two things: a US company wants to employ people in Mexico without an entity, or it wants to offload Mexican payroll and HR administration. Either way, the US co-employment model the word PEO describes does not transfer cleanly, because Mexico's 2021 labour reform prohibited general subcontracting of personnel. What remains lawful is a registered specialized service provider, or a true employer of record structure, and the difference decides whether the arrangement survives an inspection.
Why the US PEO model does not map to Mexico
A US PEO operates through co-employment: the client already has its own registered entity and shares employer responsibilities with the PEO. An employer of record, by contrast, becomes the sole legal employer in the worker's jurisdiction, which is what a foreign company with no Mexican entity actually needs. Mexico adds a layer neither US term captures: since the 2021 reform to the Federal Labor Law, supplying personnel to work in someone else's core business is prohibited. Only specialized services or works that fall outside the client's corporate purpose and main economic activity may be subcontracted, so a provider simply leasing you staff for your main line of business is on the wrong side of the law.
REPSE registration and the inspection regime
Providers of specialized services must register with REPSE, the public registry run by Mexico's labour ministry, the STPS. The obligation has teeth: an inspection protocol published on 24 November 2025 sets out three inspection types, including REPSE verification visits and targeted subcontracting reviews, with inspectors checking that the registration is valid, that the arrangement is lawful and that what workers actually do on site matches the subcontracting agreement. Before signing with any Mexico PEO or EOR, ask for its REPSE registration and check that the services described in the agreement genuinely sit outside your core activity; a mismatch between paper and practice is exactly what the protocol targets.
What employing in Mexico costs
Employer social security contributions to IMSS are calculated at varying rates against limits based on multiples of the UMA reference unit; for a low-risk company the employer's annual contribution tops out around MXN 227,286 per employee at the contribution ceiling, and the occupational risk premium varies by industry. Mexico City levies a 4% payroll tax on the employer, and other states impose similar taxes at their own rates. The floor is moving too: the general daily minimum wage rose 13% to 315.04 pesos from 1 January 2026, with a higher rate of 440.87 pesos in the northern border zone. A serious quote itemises IMSS, state payroll tax and the provider fee separately.
Choosing the structure that fits
If you have no Mexican entity, what you need is an employer of record that lawfully employs the worker itself and, where the arrangement amounts to a specialized service, holds a REPSE registration that matches what the workers will actually do. If you already have a Mexican entity and want administrative relief, managed payroll for your own entity avoids the subcontracting question entirely. What you should not buy is undifferentiated staff leasing into your core business, whatever it is branded, because the 2021 reform prohibits it and the inspection protocol now actively looks for it. Contracts and registrations control; nothing on this page is legal or tax advice.
Questions people ask about mexico peo
Is a PEO legal in Mexico?
US-style co-employment has no direct Mexican equivalent. Since the 2021 reform, supplying personnel into a client's core business is prohibited; only specialized services outside the client's corporate purpose may be subcontracted, and the provider must be registered with REPSE.
What is REPSE?
The registry of specialized service providers run by Mexico's labour ministry, the STPS. Providers of specialized services or works must register, and inspectors verify that registrations are valid and that on-site work matches the registered services.
What is the minimum wage in Mexico in 2026?
The general minimum wage rose to 315.04 pesos per day from 1 January 2026, and to 440.87 pesos per day in the northern border free zone.
PEO or EOR for a first hire in Mexico?
With no Mexican entity, an EOR structure is the fit: it is the sole legal employer and carries the compliance duties. A PEO-style shared arrangement presumes you already employ the person through your own registered entity.
