In Mexico, the Supreme Court of Justice of the Nation (SCJN) has issued a landmark decision:
Payroll CFDIs (Digital Tax Receipts via Internet) no longer require the employee’s signature to prove salary amounts and payments.
Until recently, many labor lawsuits debated whether it was necessary to keep printed, signed pay slips. Today, the Court has confirmed that:
- Payroll CFDIs are full legal proof in labor matters.
- Presenting a stamped CFDI in Court is sufficient to prove payment.
- CFDIs provide greater legal certainty than paper receipts.
What Did the Court Establish?
The jurisprudence 2a./J. 30/2020 (10th Epoch), published in the Semanario Judicial de la Federación, states that:
- Payroll CFDIs, stamped and validated by the SAT (Tax Administration Service), are entirely valid proof of payment.
- They are more substantial evidence than printed receipts, which may be disputed.
- The CFDI’s digital seal and verification chain ensure authenticity and integrity.
Impact Across Mexican Institutions
This ruling requires various institutions to recognize payroll CFDIs fully:
- Labor Boards and Courts: must admit CFDIs as sufficient proof of wage payment.
- SAT (Tax Administration Service): CFDIs are the only valid way to deduct payroll expenses and claim subsidies.
- IMSS (Social Security Institute): cross-checks CFDIs to verify contribution bases.
- INFONAVIT: relies on CFDIs for housing contributions and employee discounts.
- State Finance Departments: calculate the Payroll Tax (ISN) based on stamped CFDIs.
The printed, signed pay slip is now secondary. What truly matters for legal defense, tax compliance, and deductions is having properly stamped and stored payroll CFDIs.
What Should Companies in Mexico Do?
- Verify payroll CFDIs: make sure all are stamped adequately by the SAT and securely stored.
- Ensure delivery to employees: through email, internal portals, or proof of availability.
- Validate payment methods: deposits and transfers must match CFDI amounts and comply with the Federal Labor Law.
- Use reliable digital systems to guarantee the authenticity, traceability, and safekeeping of CFDIs.
- Train HR and payroll teams to apply and leverage this new criterion effectively.
In Mexico, payroll digitalization is no longer just about efficiency—it is now a legal shield. A properly stamped payroll CFDI not only protects companies in labor disputes but also ensures compliance with tax and social security obligations. The message is clear: the future (and the present) of payroll in Mexico is 100% digital.
