Why Companies Outsource Payroll in Mexico
Companies expanding into Mexico often use local payroll providers to:

✔️ Stay updated with frequent regulatory changes

5 Common Red Flags to Watch For
1.- Lack of REPSE Registration
After Mexico’s outsourcing reform, any specialized outsourcing provider must be registered with REPSE.
Red flag: A provider who can’t show proof of REPSE compliance could expose you to fines.

2.- No Local Tax or Labor Law Expertise
Payroll rules in Mexico are complex — especially for profit sharing (PTU), vacation bonuses, and social security contributions.
Red flag: Providers who lack local accountants or fail to adapt to new tax reforms.
3.- Vague Contracts and Service Scope
A professional payroll agreement should clearly state:
- Who files reports
- Who is liable for tax errors
- How data privacy is handled
Red flag: Vague or generic contracts that leave you exposed if something goes wrong.
4.- Suspiciously Low Fees
If a payroll provider offers rates well below market, watch out — they may be cutting corners:
✔️ Misclassifying employees as contractors
✔️ Ignoring legal profit-sharing rules
✔️ Not paying social security contributions

5.- Poor Data Security Practices
Payroll data includes sensitive employee information.
Red flag: No clear policies for encrypting and storing payroll records. This can violate Mexico’s Federal Law on Protection of Personal Data.

Legal Risks of Choosing the Wrong Payroll Provider
🔴 Fines and Back Taxes:
If your provider mishandles withholdings, the SAT can audit and fine your company, not the provider.
🔴 Labor Lawsuits:
Improper calculation of overtime or severance can trigger lawsuits.
🔴 Permanent Establishment Risk:
Poor structuring can create unexpected tax obligations in Mexico.
