How to renew your electronic certificate
When an electronic certificate is close to its expiration date, it is necessary to renew it before reaching the deadline. The certificate is invalidated on the same day that indicates the expiration date.
Depending on the certifying body and the type of certificate, it may or may not be renewable online. To renew the electronic certificate, you must access the web pages of the authorized certifying entities, specifically the entity issuing the electronic certificate. Therefore, the renewal of the certificate is a process outside the Tax Agency.
The National Mint and Stamp Factory ( FNMT ) only allows the renewal of natural person and representative certificates for sole and joint administrators.
To request electronic renewal it is necessary to authenticate with the same electronic certificate that you want to renew. The certificate must work correctly and the request must be made within 60 days before its expiration.
It should also be taken into account that if the certificate to be renewed was obtained by identifying yourself with another digital certificate or was previously renewed, a new certificate cannot be issued without proving your identity in person at a Registry Office.
If the issuing entity is FNMT , access section "Renew" and follow the instructions in step 1 "Previous configuration" , to avoid technical incidents.
Next, complete steps 2 and 3, "Request renewal" and "Download the certificate" , respectively. Additionally, after completing the process, it is recommended to make a backup copy of the certificate.
The renewal process may vary depending on the certifying entity that issues the certificate. You can consult the website of the corresponding issuing entity or contact its technical support.
