Every time a truck carrying merchandise travels through Mexico without the correct paperwork, it faces a very real risk: a fine ranging from $400 to $600 pesos for each incorrectly issued receipt, plus the possibility of the authorities seizing the cargo on the spot. The Waybill Supplement is precisely the document that prevents this scenario.
It’s part of the CFDI (Digital Tax Receipt) and serves to record information about the goods, their origin, destination, and mode of transport. If you move goods within Mexico, sooner or later you’ll need to know when it applies and what information you have to include.
The SAT (Mexican Tax Administration Service) requires it to certify the transport and legal possession of the goods, strengthen tax enforcement, and combat smuggling. Knowing the rules helps you issue the correct receipt and reduce risks during transport.
In this article, you’ll find out when issuing the supplement is mandatory, what information it must contain, how much an error costs with the SAT, and how a CFDI for goods entering the country differs from one for goods being transported. Let’s start with the essentials:
Key Points
Identify when you must issue the Waybill Addendum.
Properly record the goods, routes, and vehicles.
Avoid tax problems due to incomplete or incorrect data.
Fundamentals, Scope, and Tax Obligation
The Waybill Addendum integrates transport data into the CFDI (electronic invoice), identifies the goods, and documents their complete journey. You must issue it when transporting goods in the cases specified by the SAT (Mexican Tax Administration Service), regardless of whether you use your own vehicles or hire a third party.
Definition and Function within the CFDI
Think of the Waybill Addendum as a digital attachment that is added to an incoming or outgoing CFDI: it includes information about the goods, origin, destination, means of transport, and the people involved in the movement. Which of the two CFDIs you should use depends on your role in the operation:
If you provide the transport service, you issue an incoming CFDI with the addendum.
If you transport goods with your own vehicles, you issue an outgoing CFDI with the addendum.
If you have a foreign trade operation, review the additional requirements.
An important point: the addendum does not replace the CFDI (electronic invoice), it only supplements it with logistical data, and it is precisely what allows you to prove legal possession or the transfer of goods during an audit.
Important: The current version went into effect on July 17, 2024, according to information from the SAT (Mexican Tax Administration Service) regarding version 3.1. If you are still using an older version, your receipt is no longer valid.
Operations and taxpayers required to use the addendum: The addendum is valid almost regardless of how you move the merchandise: by truck, rail, sea, or air, according to the rules of each case, and it doesn’t matter if you use your own vehicles, hire a transport company, or make the transfer as part of a sale.
In a contracted operation, the transport company usually issues the CFDI for entry with the Bill of Lading. If you move your own goods, however, you are responsible for issuing the CFDI for transfer. In both cases, you need to provide the digital or printed representation of the bill of lading for the driver to show during the trip.
The information to be reviewed includes:
Tax ID (RFC) and names of the parties involved.
Origin, destination, and distance.
Type of transport and corresponding permit.
Weight, quantity, unit, and description of the goods.
Insurance, vehicle, and driver, when applicable.
The SAT (Mexican Tax Administration Service) website on the Bill of Lading Supplement compiles the complete assumptions, requirements, and issuance rules.
Reasons for SAT Control and Auditing
Behind this obligation lies a simple logic: the SAT wants to link the goods to a tax transaction and a specific route, comparing what is declared in the CFDI (Digital Tax Receipt) with what is actually being transported, who is sending it, who is receiving it, and where it is passing through. During an inspection, the tax authority may request the bill of lading to verify the legal possession, ownership, or transport of the goods, and this same information allows them to detect discrepancies between inventories, invoices, addresses, permits, and vehicle information.
Important: The SAT (Mexican Tax Administration Service) indicates fines of $400 to $600 for each receipt issued without the required addendum in the specified cases. This may not sound like much per receipt, but multiplied by each shipment that isn’t properly documented, the amount quickly adds up. That’s why it’s worthwhile to verify the catalogs, save the documents, and correct any data before starting the shipment, not after. Correct Issuance and Consequences of Non-Compliance: Issuing the correct CFDI (Digital Tax Receipt), capturing verifiable data, and keeping the shipment documentation is not optional: an error can cause fines, merchandise seizures, problems deducting expenses, and full tax audits. Essential Data It Must Contain: The Bill of Lading is integrated into CFDI 4.0 through the Bill of Lading 3.1 addendum, the current version for receipts applicable since July 17, 2024. Among the data you must include are…
