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

On 16 March 2021 the Tax Agency will change the electronic certificates used to provide services to taxpayers.This change will make it possible to continue accessing the Tax Agency's e-Office services without the risk of access being prevented by the browser normally used.

The new electronic certificates will be signed by the certification service provider GlobalSign.These electronic certificates are recognised by all major browsers and the Java Virtual Machine.The domains affected by this change are:

  • agenciatributaria.gob.es

  • agenciatributaria.es
  • aeat.es

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

These GlobalSign AC ROOT and AC INTERMEDIA public keys are attached below so that they can be downloaded and configured if necessary.
