An introduction to the importance of payment concepts in electronic bank transfers.

• Payment concepts are brief descriptions crucial for banks and users to identify and classify transactions.
• Choosing inappropriate words for these concepts can lead to issues, including with tax authorities like Mexico's SAT.

Guidance on how to properly draft payment concepts for bank transfers to avoid problems.

• Use banking apps from banks like BBVA, Santander, Citibanamex, HSBC, Banco Azteca, Banorte, and others with caution when transferring money.
• Adopt practices to draft payment concepts that are not suspicious or inappropriate.
• Provide clear and concise information that describes the transfer purpose to avoid ambiguity.

Explanation of how the tax authorities, such as Mexico's SAT, use advanced systems to detect suspicious or inappropriate terms.

• SAT has access to transaction details and uses advanced systems, including artificial intelligence, to detect potential illicit activities.
• It is crucial to abstain from using terms associated with illegal activities or that appear to be jokes.

Specific recommendations on what to include in payment concepts to avoid misunderstandings and investigations by tax authorities.

• Payment concepts should be clear and direct, such as 'medical services payment', 'school fee', or 'rent transaction'.
• Use complete and correct names, and avoid leaving the description field blank, as an empty concept can be problematic.
