This renewal does not affect users of the Agency's electronic headquarters, who will be able to continue accessing it as usual .

On November 17, 2022 the Tax Agency will proceed to renew the electronic certificate of the electronic headquarters.

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 this new electronic certificate, since the Intermediate CA that signs the new electronic certificate of electronic headquarters changes. To do this, you will need to check whether your systems trust this new INTERMEDIATE AC.

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

• Root Certification Authority ( AC ROOT ) of the domain certificate sede.agenciatributaria.gob.es

• Intermediate Certification Authority ( INTERMEDIA AC ) of the new certificate for the domain sede.agenciatributaria.gob.es

The new certificate for the electronic headquarters is also attached.
