The digitalization of fiscal and administrative processes has facilitated online procedures. One of the key elements to ensure the authenticity of these processes is the electronic signature or e-signature. In this article, you will learn what it is, how to process it, and what it is used for in the fiscal and business environment.

What is the electronic signature?

The electronic signature is a set of data in digital format that allows the identification of a person and validates documents or transactions online with the same legal validity as a handwritten signature. In Mexico, the Tax Administration Service (SAT) refers to it as e-signature, and it is used in various fiscal and legal procedures.

This tool works through cryptographic keys that ensure the security and authenticity of digitally signed documents, preventing fraud or alterations.

Who needs an electronic signature?

The e-signature is necessary for various individuals and entities that carry out fiscal and administrative procedures. Some of the most common cases include:

• Individuals and legal entities registered with the SAT: It is essential for filing tax returns, issuing electronic invoices, and carrying out other tax procedures.

• Business owners and entrepreneurs: It facilitates the signing of contracts and digital agreements, speeding up legal and administrative processes.

• Freelancers and independent professionals: It is necessary for issuing invoices and complying with tax obligations.

• Employees and officers of companies: In some companies, the electronic signature is a requirement for managing official documents and signing reports or contracts.

• People performing government procedures online: Such as registrations with the RFC, credit applications, or filing sworn statements.

How to process the electronic signature?

To obtain the e-signature, it is necessary to undergo a process with the SAT. The steps are as follows:

1. Gather the requirements:

   • Unique Population Registry Code (CURP)

   • Valid official identification

   • Recent proof of address

   • USB memory unit to store the generated files

2. Schedule an appointment with the SAT: Go to the SAT portal and select the e-signature application option to schedule an appointment at the nearest office.

3. Visit the SAT office: During the appointment, your biometric data (fingerprints, photograph, and signature) will be collected, and the e-signature files will be generated (key file, certificate file, and access password).

4. Download and store the e-signature: Once generated, the SAT will provide a digital file that you must keep in a safe place for use in future procedures.

What is the electronic signature used for?

The e-signature has various applications in both the fiscal and business fields. Some of its main functions are:

• Tax declarations and procedures: Allows the filing of annual tax returns, invoicing, and making requests to the SAT.

• Signing digital contracts: Companies and entrepreneurs can use it to sign agreements and contracts without the need to be present.

• Procedures before government institutions: It is used in processes such as registration in the Federal Taxpayers Registry (RFC) and other official procedures.

• Access to digital platforms: Various online services require validation through e-signature to ensure user authenticity.

Conclusion

The electronic signature is an indispensable tool for streamlining fiscal and business procedures with security and legal validity. Obtaining it is a simple process that offers great benefits to taxpayers and businesses.
