What is a digital certificate?
The electronic certificate is a digital signature installed onto your browser to certify your identity when you are online. It allows you to perform operations from your own computer (such as accessing your tax data, submitting tax returns online, making payments or requesting and collecting certifications directly from the Tax Agency website).
The electronic certificate is not requested through the Tax Agency's website but through the website of an issuing entity.
The procedure for obtaining a certificate that allows you to identify yourself on the AEAT website may vary depending on the issuing entity.Likewise, in the event of incidents in applying for or obtaining the certificate, it is necessary to contact the corresponding issuing entity, as the requirements and circumstances may vary from one issuing entity to another.All issuing entities have help options and services that can be accessed from their websites.
How does the electronic DNI work?
The AEAT website supports identification and signature by means of the electronic DNIs.To use it, you need certain pieces of hardware and software that can access the card's chip, and therefore access the certificates contained in it.In addition, the certificates must remain valid as they expire 24 months after the issuance of the DNI, if they are not renewed before at one of the Update Points of the DNI located in the issuing offices, and the PIN that protects access to the functionalities in the DNIe must be known.
When accessing an option on the web page that requires an electronic certificate, the browser must request the PIN and then display the certificate store to be able to choose the corresponding one (authentication or signature).
