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

The next November 21, 2025 The Tax Agency will proceed to renew the electronic certificate of the Electronic Office.

In the case of entities that access from applications developed specifically to use the services of the Tax Agency, it is necessary to confirm that their systems will accept this new electronic certificate, since the ROOT CA and the INTERMEDIATE CA that signs the new electronic certificate of the Electronic Office change. To do this, they will need to check if their systems trust these new Certification Authorities.

Attached below are the AC ROOT and AC INTERMEDIA public keys, which can be downloaded and configured if necessary.

Also attached is the new certificate from the Electronic Headquarters.
