How do you hire a Mexico employee in 2026?
Mexico has no advance notice requirement. An employer can terminate immediately. But if you fail to include a probation clause in the written contract, the employee gains indefinite status from day one. That single drafting gap is the most common hire mistake in Mexico.

The Mexico hire process has five steps. Offer letter, work-authorisation check, written employment contract, IMSS registration, first payday.
The written contract must include a valid probation clause. Without it, the employee has indefinite status from day one.
Probation is 1 month for standard roles and up to 6 months for managers and specialists. Mexico has no advance notice requirement for either side.
What does the end-to-end Mexico hire process look like?
Five steps from accepted offer to first payslip: offer letter, work-authorisation check, written employment contract, IMSS registration, first payday.
The written contract is the critical step. A missing or invalid probation clause removes your ability to end the hire during probation without triggering severance.
| Step | What happens | Owner | Timing |
|---|---|---|---|
| 1. Offer letter | Written offer with role, salary, start date, and key terms | Client / Teamed drafts | Same day after verbal accept |
| 2. Work-authorisation check | Verify citizenship or FM3/FM2 visa with work authorisation for non-Mexican nationals | Teamed | Before the employee starts |
| 3. Written employment contract | Contract under the Ley Federal del Trabajo including valid probation clause, role, salary, working hours, and leave entitlement | Teamed (legal employer) | On or before day one |
| 4. IMSS registration | Register the employee with the Instituto Mexicano del Seguro Social; file the AFORE pension notice | Teamed | Days 1 to 5 |
| 5. First payday | First quincenal or weekly payslip issued; ISR withheld and remitted to SAT by the 17th of the following month | Teamed | End of first pay period |
-
Issue the offer letter
Send a written offer the same day as verbal acceptance. Include role, gross salary, start date, and any conditions such as work-authorisation or references. Note that Mexico has no advance notice requirement for either side.
-
Complete the work-authorisation check
Verify Mexican citizenship or confirm the non-national holds a valid immigration document permitting work. Retain a copy. This must happen before the employee starts.
-
Issue the written employment contract
The contract must include a valid probation clause or the employee has indefinite status from day one. Standard probation is up to 1 month; managerial and specialist roles can extend to 6 months. Teamed signs as the legal employer.
-
Complete IMSS and payroll registration
Register the employee with IMSS, file the AFORE pension notice, and collect the CURP, RFC, and CLABE bank details. This runs across days 1 to 5.
-
Issue the first payslip and file ISR
Run the first quincenal payroll at the end of the first pay period. Withhold and remit ISR to SAT by the 17th of the following month. The employee receives their payslip and is on the payroll record.
What must a Mexico offer letter include?
The offer letter is not the binding contract. It is the document the candidate decides against.
Include role title, reporting line, start date, gross monthly or fortnightly salary, working pattern, location, and any conditions such as work-authorisation or reference checks.
Three traps to avoid in Mexican offer letters:
- Quoting net salary. Mexico's payroll involves IMSS deductions and ISR withholding that change with salary level. Committing to a net figure creates problems when those calculations shift. Quote gross only.
- Describing probation in the offer letter but not the contract. The probation clause is only valid when it appears in the written employment contract signed by both parties. An offer letter reference to probation does not create a valid probation period. If the contract is missing the clause, the employee has indefinite status from day one.
- Promising benefits not yet agreed. Mexico law requires the Aguinaldo (Christmas bonus) of at least 15 days of salary and the prima vacacional (vacation premium) of at least 25% of vacation salary. Promising amounts above those minimums in the offer letter creates a contractual floor that is very hard to reduce later.
Teamed's standard Mexico offer letter template covers all required disclosures without overcommitting. Clients choose commercial elements. Teamed holds the legal-employer position and issues the contract under Mexican law.
Mexico work-authorisation checks
Mexican nationals can work freely. Non-Mexican nationals need a valid immigration document that authorises employment before they can start.
The employer must verify the document before the employee starts and keep a copy on file.
Mexican nationals
Citizens of Mexico have an unrestricted right to work. The employer checks and copies a valid national identity document (CURP card, passport, or INE voter card) before the start date. No government portal or online check is required.
Non-Mexican nationals
Foreign nationals must hold a valid immigration document that explicitly permits paid employment. The main categories are:
- Temporal Resident with permission to work (Residente Temporal con permiso para trabajar): issued by the Instituto Nacional de Migración (INM). Valid for up to 4 years. Most common route for company-sponsored hires.
- Permanent Resident (Residente Permanente): no work-authorisation condition. Residents with this status work freely.
- USMCA/T-MEC professionals: citizens of the United States or Canada in covered professional categories can obtain a work-authorisation entry under the trade agreement. Employer files the sponsorship form with INM before the employee enters.
The employer must verify the expiry date of any time-limited permit and run a follow-up check before it expires. An employee working beyond a permit's validity is an immigration compliance breach.
Foreign nationals who wish to carry out paid or unpaid activities in Mexico must hold a valid immigration document that includes permission to work. Employers must verify this document before the employee starts work and retain a copy in the employment file.

Ongoing checks for time-limited permits
Teamed tracks each permit expiry date and triggers a reminder before renewal is needed. A permit that lapses without renewal creates personal liability for the employee and potential administrative sanctions for the employer.
The Mexico written contract: what must it contain?
Every employee must have a written employment contract under the Ley Federal del Trabajo. There is no grace period.
The contract must be in place on or before day one. A verbal arrangement does not meet the requirement.
What the Mexico written employment contract must include under the Ley Federal del Trabajo (LFT):
- Names and addresses of both parties
- Whether the contract is indefinite, fixed-term, or for a specific project
- Start date of employment
- Place of work, or a note that the employee works across multiple sites
- Job title and brief description of duties
- Working hours and schedule: the maximum day-shift week is 48 hours through 2026
- Salary (gross) and payment frequency: the law sets a maximum interval of 15 days between payments for non-manual workers
- Annual leave entitlement: at least 12 days after the first year of service under the Vacaciones Dignas reform, plus a prima vacacional of at least 25% of vacation salary
- Probation period, if any: must be stated explicitly or it has no legal effect. Standard roles: up to 1 month. Managerial and specialist roles: up to 6 months.
- IMSS affiliation details once the employer code is active
- Aguinaldo (Christmas bonus) terms: the legal minimum is 15 days of salary paid before 20 December each year
- Any additional benefits agreed (savings fund, food vouchers, transportation allowance)
- Confidentiality and non-compete provisions, if applicable
Mexico's LFT requires the contract to be in Spanish. A bilingual version is permitted, but the Spanish text governs in any dispute. Teamed's standard Mexico contract is drafted in Spanish and covers all LFT requirements. Clients choose commercial terms; Teamed signs as the legal employer.

Frequently asked questions
How long does it take to hire someone in Mexico through Teamed?
Teamed can onboard a Mexican national within a few business days. The critical path is the written employment contract and IMSS registration. Non-Mexican nationals who need immigration work-authorisation must have that in place before the start date, which adds lead time depending on the permit category.
What is the probation period in Mexico and how does it work?
Standard roles have a maximum probation of 1 month. Managerial, technical, and specialist roles can use up to 6 months. The probation clause must appear in the written employment contract signed by both parties. If the clause is absent or improperly drafted, the employee has indefinite-term status from day one and full severance protection applies immediately.
Does Mexico require advance notice before terminating an employee?
No. Mexico has no advance notice requirement. An employer can terminate on the spot. Termination during a valid probation period for unsuitability requires no notice. After probation ends, dismissal without a just cause triggers the constitutional indemnity (3 months salary plus 20 days per year of service) but no notice period.
What annual leave does a Mexico employee receive?
After the first year of service, the minimum is 12 days of paid leave under the Vacaciones Dignas reform. Leave increases by 2 days per year through year 5. Employees also receive a prima vacacional (vacation premium) of at least 25% of their vacation salary on top of the leave days. Mexico has 7 official mandatory rest days per year.
What is the working week limit in Mexico in 2026?
The maximum day-shift working week is 48 hours through 31 December 2026. A reform published in May 2026 reduces this to 46 hours from 1 January 2027, then to 44 hours in 2028, 42 hours in 2029, and 40 hours in 2030. Employers must implement electronic time-tracking under the reform.
The probation clause is not a detail. It is the structure of the relationship for the first month. We have seen companies onboard their first Mexico hire, skip the clause because the contract was a template from another country, and then face a full severance exposure from week two. The contract has to be right before day one, not corrected after.
Mexico gives you 1 month to assess a standard hire. The clock runs from the contract date.
The written contract is not paperwork to sort later. It sets the terms from day one.
