Electronic Invoicing

CFDI - Electronic Invoicing in Mexico

mexico electronic invoice

Electronic invoicing in Mexico has transformed how companies manage tax obligations and optimize internal operations. Since the introduction of the CFDI (Comprobante Fiscal Digital por Internet), mandated by the Tax Administration Service (SAT), organizations are required to issue and receive electronic invoices, ensuring compliance with Mexico’s tax regulations.

As the foundation of electronic invoicing in Mexico, the CFDI has become essential for business growth and competitiveness in an increasingly digital landscape. To comply with SAT regulations, companies must adopt technological solutions that not only streamline the issuance of CFDIs but also validate them in real time and integrate efficiently with administrative processes. Meeting the electronic invoicing requirements set by the tax authority is critical to operating securely and avoiding penalties.

What is CFDI 4.0?

CFDI 4.0 is the current version of the Digital Tax Receipt via Internet, effective as of January 1, 2022. It is now mandatory for taxpayers to use this version to issue their electronic invoices, replacing the previous version in Mexico (CFDI 3.3).

CFDI 4.0 impacts all processes related to the issuance and reception of electronic invoices, as well as other related documents, such as withholding receipts, payment complements, Bill of Lading, and Payroll, among others.

Main changes in CFDI 4.0

The latest version of the electronic invoice (CFDI) introduces the following changes:

  • A new element affecting global/recapitulative invoices (this measure will directly impact ticket portals and Point of Sale invoicing solutions).
  • The inclusion of the receiver's Postal Code and tax regime.
  • The receiver's name is now mandatory and must be validated.
  • An attribute is added for primary sector cases.
  • A new attribute indicates whether the CFDI covers exports.
  • At the concept level, a new attribute indicates whether it is subject to tax.
  • The third-party account complement is replaced by a new element at the concept level.
  • Adjustments in validation rules.

The CFDI electronic invoice version 4.0 introduces a requirement for pre-validation of all tax data registered with the SAT, both for individuals and legal entities, before stamping any electronic voucher. Therefore, all taxpayers must ensure that their information registered with the SAT is correct and up to date. As an accredited PAC, we recommend verifying your tax details and generating a record of your current status.

Format of the Withholding and Payment Information Voucher version 2

The Withholding Voucher is a document that records tax withholdings and payments made by taxpayers residing abroad. This digital tax receipt affects various operations, such as payments related to dividends, trust leases, share sales, non-business trusts, interests, mortgage interests, payments to foreign entities, retirement plans, prizes, derivative transactions, and the financial sector.

The new version of the Withholding and Payment Information Voucher (version 2) includes the following changes:

  • An attribute for the place of issuance, similar to the CFDI.
  • A node for related CFDIs, as seen in the CFDI format.
  • Attributes for the issuer's tax regime, the receiver's Zip Code, and mandatory names for both issuer and receiver.
  • New attributes in the totals for profits and ISR (Income Tax), which are conditional.
  • A defined pattern for the FolioInt (reference).
  • Adjustments to validation rules and catalogs.

Payment Complement version 2

The Payment Complement, which must be issued together with the CFDI when payments are made in installments or deferred, also updates its format with the following new features:

  • A field to specify the total amount from the Payment nodes.
  • An attribute indicating whether the payment is taxable or not.
  • A new element detailing taxes, including Transferred and Withheld taxes.
  • The Payment Complement can now only be used with voucher type 'P'.
  • Updates to validation rules and catalogs.

CFDI Foreign Trade Complement

The foreign trade complement for CFDI is an annex to the electronic invoice that identifies exporters and importers while providing a more detailed description of traded goods. Its objective is to enhance security and fiscal control in international transactions. Beyond that, it also represents a step forward in standardizing electronic documents used in foreign trade. In fact, this complement could eventually replace the Electronic Value Voucher (COVE).

The CFDI for the exporting sector must include data related to the type of operation, customs declaration code, certificate of origin, exporter’s number, and exchange rate. Additionally, it must capture the tax registration identifier of the recipient in their country of residence (e.g., Tax ID in the United States), their address, and a description of the declared package with specific characteristics.

Foreign Trade Complement Version 2.0

The Tax Administration Service (SAT) released version 2.0 of the Foreign Trade Complement, which came into effect on January 18, 2024, according to the updated catalogs. Unlike the previous version, no new fields have been added, but four fields that were previously optional are now mandatory.

Full details on the structure, standards, and catalogs can be found in the technical documentation available on the SAT's web portal.

Key changes in the structure of the complement include:

  • New Prefix and Namespace: A new prefix and namespace have been defined for this version.
  • Foreign Trade Section: The default value of the “Version” field has been updated to 2.0, and the attributes “TypeOperation” and “Subdivision” have been removed.
  • Issuer Section: The “Domicile” node, previously optional, is now required.
  • Goods Node: This node is also now mandatory. Additionally, the “CustomsUnitValue” attribute has been expanded to 6 decimal places, and the “DollarValue” attribute to 4 decimal places.

The most recent update to this complement was announced on January 18, 2024, when the SAT reported improvements to the "original string sequence (xslt)" as well as updates to the “c_RegimenFiscal” and “c_Currency” catalogs in the Foreign Trade Complement.

Who is Affected by the Foreign Trade Complement?

Taxpayers involved in foreign trade operations, specifically in definitive exports under key A1 subject to alienation as per article 14 of the Federal Tax Code, must use this complement. This initiative is not limited to Mexico; the SAT has established interoperability agreements under the North American Free Trade Agreement, covering over 80% of the country’s exports.

These agreements with the tax authorities of the United States and Canada will enable Authorized Certification Providers (PAC) to verify the identity of the package recipient, check the invoice status, and access all transaction details. This will enhance security and fiscal control in the movement of goods, reducing the risk of counterfeiting and tax evasion.

Payroll CFDI Complement 4.0

A Payroll Digital Tax Receipt (CFDI) is a type of electronic invoice that reflects the amount paid by a company to its employee for services rendered during a specific period. This digital document must be stamped by an authorized PAC (Authorized Certification Provider) to have fiscal validity and can then be submitted to the SAT (Tax Administration Service).

This complement allows employers to detail the payments made to their employees, covering items such as salaries, bonuses, benefits, and deductions for taxes or social security. Its use is mandatory for all employers issuing payroll, as it promotes transparency in labor relations and ensures compliance with tax obligations.

Main Changes in CFDI 4.0

  • The date format for the attributes PaymentDate, InitialPaymentDate, FinalPaymentDate, and LaborRelatedStartDate is standardized according to Annex 20.
  • Validations for the version and form of payment have been removed.
  • New validations have been added for issuing the complement with CFDI version 4.0, including attributes like RegimenFiscalReceptor, ObjetoImp, ACuentaTerceros, InformacionAduanera, CuentaPredial, ComplementoConcepto, and Parte.
  • Additionally, as part of the integration with CFDI version 4.0, the recipient's RFC, name, tax regime, and zip code are now mandatory for issuing payroll receipts.

CFDI Complement for Airlines

Airlines in Mexico are required to issue Digital Tax Receipts via Internet (CFDI) for the sale of airline tickets, as established by the seventh transitory article of the First Resolution of Amendments to the Miscellaneous Tax Resolution.

To meet this legal requirement, EDICOM has developed the CFDI Airlines portal, a solution that automates the online sending of receipts requested by passengers and streamlines their reporting to the SAT.

CFDIs issued by airlines must comply with all tax requirements and be readily available to customers. Depending on their operational needs, airlines may generate various types of CFDIs, such as those for income, expenses, or payroll.

It is crucial for airlines to choose a reliable, SAT-certified provider for issuing electronic invoices. This not only ensures the security and validity of the CFDI but also optimizes the invoicing process, ensuring compliance with current tax regulations in Mexico.

How to Obtain the CFDI for Airline Tickets

Purchases at Counters, Offices, or by Phone
If the ticket is purchased at airport counters, sales offices, or by telephone, customers must provide their Federal Taxpayers Registry (RFC) and an email address. The airline has up to two business days from the payment date to generate and send the CFDI via email. If customers do not have the required information at the time of purchase, they can later provide the missing details to the airline to receive their electronic invoice.

Online Ticket Purchases
For tickets purchased through the airline's website, customers must access a link where they can enter their tax details. As with in-person purchases, the airline has up to two business days from the payment date to send the CFDI via email.

Purchases through Travel AgenciesWhen tickets are bought through travel agencies, the agency is responsible for managing the issuance and delivery of the CFDI. To streamline this process, EDICOM has developed a solution that enables agencies and large companies to automatically generate CFDIs for airline tickets.

How does the CFDI Airlines Portal work?

EDICOM's CFDI Airlines portal allows airline customers to generate their invoices simply and quickly. The process works as follows:

  • The customer accesses a secure web portal where they enter their ticket data and the tax information required for issuing the CFDI.
  • The EDICOM platform connects to the airline's management system, verifies the data provided, and generates the CFDI.
  • As an Authorized Certification Provider (PAC), EDICOM certifies the receipt and reports it to the SAT, granting it tax validity.
  • The customer receives the CFDI in XML format, along with a graphical representation in PDF, which can be downloaded or printed.
  • The portal is integrated with the airline's accounting management system, enabling automated administration of the issued CFDIs.

EDICOM has developed a secure portal that automates the online delivery of tax receipts to passengers who request them and facilitates filing these documents with the SAT. 

Airlines such as Volaris, American Airlines, Delta, Iberia, KLM, Lufthansa, and Air France rely on EDICOM's CFDI Airlines solution. This tool not only ensures compliance with SAT tax regulations but also optimizes the management process through complete automation.

CFDI Cancellation: How to Cancel Electronic Invoices

In 2018, Mexico's Tax Administration Service (SAT) took measures to prevent the improper cancellation of CFDIs, a widespread issue affecting numerous taxpayers. 
The implementation of the CFDI 4.0 scheme introduced new features to the cancellation system that has existed since 2018, making it mandatory to specify the reason for canceling each invoice.

In what cases can a CFDI be canceled?

The new tax cancellation policy introduced by the Mexican government aims to put an end to the bad practice of some companies canceling their electronic invoices without their customers' knowledge. This practice allows companies to omit income from their tax reports, affecting Income Tax calculations, while customers who have already paid for the service or product are unable to deduct the expense.

Additionally, if an error occurs in generating the CFDI—such as incorrect fiscal data for the recipient, mistakes in the amounts, or inaccuracies in the description of the product or service, or in the payment method—cancellations can be requested.

With the implementation of information and acceptance mechanisms, invoices can only be canceled if the recipient agrees to the cancellation. This ensures that customers have the assurance that, once a service has been paid for, the invoices covering that expense will not be canceled without their consent. It is also possible to automatically cancel invoices, credit and debit notes, as well as payroll and withholding documents.

As of January 1, 2022, it is mandatory to specify the reason for the invoice cancellation. The SAT has outlined four possible options:

  1. Voucher issued with errors with relation: Applies when an invoice contains errors in the product key, unit value, discount, or other details, necessitating reissuance. In this case, the original invoice is replaced, and the replacement invoice's folio is referenced during cancellation.
  2. Invoice issued with unrelated errors: Applies when the invoice contains errors in the product key, unit value, discount, or other details without needing to reference another invoice.
  3. The transaction was not carried out: Applies when an invoiced transaction does not materialize.
  4. Nominative operation related to the global invoice: Applies when a sale included in the global invoice for public transactions needs to be replaced by a nominative invoice upon customer request, requiring the cancellation of the original global invoice and issuance of the specific invoice.

How is the CFDI Cancellation process performed?

 

  1. The CFDI cancellation process under the new policy is included in the Miscellaneous Fiscal Resolution for 2017 and its Annex 19.
  2. Issuers must send a cancellation request to the recipient of the CFDI through the SAT Portal or via a certification provider's services.
  3. As of January 1, 2022, with the new CFDI 4.0 scheme, it is mandatory to indicate the reason for the cancellation. This requirement applies to all versions of the invoice or CFDI.
  4. If acceptance for cancellation is required, the invoice recipient will receive a notification in their Tax Mailbox, informing them of the cancellation request.
  5. From that point, the recipient has 72 hours to either accept or reject the cancellation of the CFDI. The response must be provided through the same Tax Mailbox. If, after the 72-hour period, the recipient has not responded, the SAT will assume that the cancellation of the CFDI has been accepted.

Mandatory Use of the Tax Mailbox

One of the most significant aspects of this new procedure is the mandatory use of the Tax Mailbox. This tool, created by the SAT to communicate directly with taxpayers, was previously used only sporadically. In fact, it is estimated that by the end of 2016, only about 2 million taxpayers, out of the 26 million issuing electronic invoices, were actively using it.

For handling cancellation requests, the EDICOM solution can automatically download these requests into the customer's internal management software, allowing for quick and convenient acceptance or rejection. This eliminates the need for constant access to the Tax Mailbox and optimizes the processing time of electronic documents.

Exceptions: Cancellation without acceptance

In certain cases, taxpayers may still cancel their CFDIs without requiring the recipient's acceptance. These exceptions are outlined in Article 29-A and include the following:

  • When the electronic invoice has a maximum amount of 5,000 pesos.
  • When it is a CFDI for payroll, expenses, transfers, or income issued to taxpayers under the Tax Incorporation Regime (RIF).
  • When the CFDI is issued using the Mis Cuentas (My Accounts) tool in the Factura Fácil (Easy Invoice) application.
  • When covering withholdings and payment information.
  • When issued for transactions with the general public under rule 2.7.1.24 or for residents abroad for tax purposes under rule 2.7.1.26.
  • When the cancellation is made within 72 hours immediately following the issuance of the CFDI.

EDICOM PAC: Automated solution for cancelling CFDIs

To cancel invoices, it is necessary to use the services of an Authorized Certification Provider (PAC) such as EDICOM. In this process, the PAC is responsible for certifying and reporting to the SAT the invoice for which the cancellation request is made. Once completed, the invoice is reflected in the SAT records as canceled, and users can verify it through the taxpayer portal.

EDICOM's CFDI Platform is fully compliant with the technical and legal requirements of the SAT. EDICOM has integrated an invoice cancellation service into its CFDI solution, streamlining day-to-day administrative management. With this system, users can cancel erroneous invoices instantly, easily, and efficiently. Moreover, this action can be performed for a single CFDI or in bulk.

The EDICOM cancellation service is available across all solutions. Users only need to click on the “cancel” option in the context menu for manual solutions. In integrated versions, users can simply utilize the method developed for automatic or mass cancellation of CFDIs, whether they are invoices, credit and debit notes, payroll, or withholding documents.

This solution allows taxpayers to fully leverage electronic invoicing, reducing the steps required for generating, issuing, and communicating receipts.

CFDI Mass Download Service

The CFDI Mass Download service enables companies to retrieve all their receipts directly from the SAT database. With the capacity to download up to 200,000 receipts per request, this solution integrates seamlessly with the EDICOM platform, providing users with easy, secure, and efficient access to their tax documents.

Key advantages of this service include:

  • Intuitive web interface: Users can submit download requests via a simple graphical interface, defining parameters that best fit their needs, allowing for quick and hassle-free management of CFDIs.
  • Recurring download scheduling: Automate the download of your CFDIs based on predefined parameters, eliminating the need for manual intervention for each request.
  • EDICOM integration API: For companies requiring advanced integration, EDICOM offers an API to automate download requests through WebServices, speeding up CFDI retrieval directly from your network infrastructure
