On June 1, 2021, the SAT announced that legal entities may continue to renew the e-signature from the website provided that the expiration date of the same does not exceed one year to the date of application.
To carry out the renewal from the portal, the following requirements must be met:
- Expired e-signature files (Certificate, private key and password).
- Have maintained the same legal representative and have an active e-signature.
- Download the Certificate application.
This procedure can be found on the SAT portal in the section Companies/other formalities and services/ Request for renewal of the Certified e-signature expired for legal entities.
