Payroll outsourcing Mexico
for your local team
We manage the full payroll cycle for your Mexico-based employees. CFDI 4.0 invoicing, IMSS social security, INFONAVIT housing fund and income tax withholding. Direct contract, no SaaS intermediary.
What Mexico payroll outsourcing includes
When you outsource Mexico payroll to ADN Services, you get a dedicated accountant who runs your entire payroll cycle. Not a platform you log into. A team that does it for you, every week or every two weeks.
- Payroll calculation: base salary, overtime, bonuses, commissions
- CFDI 4.0 electronic payroll receipts (Mexico's required invoicing standard since 2022)
- Income tax (ISR) withholding calculation and monthly reconciliation
- IMSS employer and employee social security contributions
- INFONAVIT housing fund contributions and credit deductions
- SUA monthly filing for IMSS payments
- Employee registrations, terminations and salary changes in IDSE (IMSS portal)
- PTU (profit sharing) annual calculation
- Salary disbursement file for your bank or coordination of direct transfer
- Monthly reports for your finance team or external auditors
Why Mexico payroll is different from US or EU payroll
Mexico has a unique combination of employer obligations that catch most foreign companies off guard:
CFDI 4.0 invoicing
Every payroll receipt must be electronically stamped through an authorized PAC (tax stamp provider). No exceptions since 2022.
IMSS contributions
Total employer contribution is approximately 20-25% of salary depending on the risk category. Filed monthly via SUA.
Mandatory benefits
Aguinaldo (Christmas bonus, 15 days minimum), vacation days, vacation premium (25%), IMSS, INFONAVIT and PTU profit sharing.
REPSE for specialized services
If you provide specialized services to a Mexican company, you need an active REPSE registration. ADN has one.
Frequently asked questions
How fast can you start running our Mexico payroll?
Typically 5 business days from signed contract. We need your employees' payroll history for the current year, existing employment contracts, and access to your IMSS employer registration. We walk you through exactly what to send.
Do we need to set up a Mexican legal entity first?
Not necessarily. Depending on your setup, we can work with your existing entity or through our PEO/EOR structure. Tell us your situation and we will recommend the right approach. See our PEO Mexico and EOR alternative services for more detail.
What does Mexico payroll cost per employee per month?
Service fees depend on number of employees and payroll frequency. We provide a fixed monthly fee per employee so you can budget accurately. Mandatory employer costs (IMSS, INFONAVIT, etc.) are separate and pass through at actual cost. Contact us for a specific quote.
Can you handle payroll for employees in different Mexican states?
Yes. We handle multi-state payroll including correct calculation of ISN (Impuesto sobre Nominas), the state payroll tax that varies by state. We need the corresponding IMSS employer registration for each state where you have employees.
