Digital payroll and CFDI: controls worth reviewing

Payroll stamping through CFDI is an obligation that affects all companies in Mexico that have workers. In 2026, requirements have become stricter and errors in stamping can have significant tax and labor consequences.

What is the payroll CFDI?

The Digital Tax Invoice (CFDI) for payroll is the tax document that supports the payment of salaries and other benefits to workers. It must be issued for each payroll payment and contains detailed information about the worker's income and deductions.

Changes in CFDI 4.0 for payroll

Version 4.0 of the CFDI, which came into force in 2023, introduced important changes for payroll stamping. The most relevant include the obligation to include the worker's RFC (the generic RFC is no longer accepted for workers with RFC), validation of the worker's name against the RFC in the SAT registry, and inclusion of the postal code of the worker's tax address.

The most common errors in payroll stamping

Incorrect or unvalidated RFC. It is the most frequent error and can result in the expense not being deductible for the company. All worker RFCs must be validated in the SAT registry before stamping.

Incorrect classification of income. Each income item has a specific code in the SAT catalog. Incorrect classification can generate inconsistencies that the SAT detects in its automatic reviews.

Incorrectly calculated deductions. ISR, IMSS and INFONAVIT must be calculated precisely. Errors in these calculations can generate differences that result in SAT or IMSS requirements.

Consequences of non-compliance

A poorly issued payroll CFDI can result in payroll expenses not being deductible for ISR purposes, SAT fines, and labor contingencies if the worker cannot prove payment of their benefits.

EFES may support administration and review of these processes within an agreed scope. No service removes employer responsibility or replaces applicable legal and tax validation.
