The electronic certificates used on the Tax Agency's e-Office and Portal are going to change

On March 16, 2021 the Tax Agency will proceed to change the electronic certificates used to offer services to taxpayers. This change will allow users to continue accessing the services of the Tax Agency's Electronic Office without the risk of being prevented from accessing the browser they normally use.

The new electronic certificates will be signed by the certification service provider GlobalSign . These electronic certificates are recognized by major browsers and the Java virtual machine. The domains affected by this change are:

  • agenciatributaria.gob.es

  • agenciatributaria.es
  • aeat.es

In the case of entities that access from applications developed specifically to use the services of the Tax Agency it is necessary that they confirm that their systems will support the new electronic certificates when invoking the services. To do this, you will need to check whether your systems trust the certificates from the Certification Authority (CA) with which the new electronic certificates from the Tax Agency will be signed.

Attached below are the GlobalSign AC ROOT and AC INTERMEDIATE public keys so they can be downloaded and configured if needed.
