The Tax Administration Service (SAT) informed that taxpayers whose status has been modified will not need to carry out additional procedures, according to an official statement. The validation of the electronic signature can be carried out on the official SAT website, specifically in the section for other procedures and services.
In case legal entities go to carry out procedures with a legal representative different from the original, they must present a certificate of incorporation and a notarial instrument that proves the legal representation. The e-signature, a unique encrypted file, has various applications, such as filing annual declarations, requesting tax refunds, issuing invoices, among other procedures with government agencies.
The e-signature has a validity of 4 years and can be renewed online up to 24 hours before it expires. The SAT has released the list of appointment availability for in-person assistance at its modules and decentralized offices throughout the country. Additionally, the SAT recently faced a massive failure by revoking the Advanced Electronic Signature of thousands of companies and taxpayers, despite the certificate still being valid, which created difficulties in carrying out tax procedures.
The SAT announced the restoration of the validation of the affected electronic signatures. To verify the validity of the e-signature, users must access the corresponding section on the platform, enter the requested data, and corroborate the information about the validity of the certificate. In case the e-signature is not valid, has been revoked, or relevant information has been lost, it is recommended to go to a SAT module with the required documentation to renew the process.
