The company certificate, now in digital format


The FNMT-RCM issues different types of digital certificates, which depending on their recipients , can be:

  • From natural person
  • From legal entity
  • From an entity without legal personality

In this case, a company would be interested in the second one. Currently, the FNMT-RCM issues electronic certificates of legal entities recognized in the tax field. Therefore, the accreditation procedure can only be carried out through the Post Office, in addition to the already existing procedure in the offices of the Tax Agency, the Autonomous Community of Navarre or the National Securities Market Commission.

It links to its subscriber (taxpayer) some signature verification data and confirms its identity. The subscriber of the same will be a legal entity, understood as a group of persons grouped together to form a unit with its own purpose, which, as an entity, acquires legal capacity and capacity to act different from that of the members that compose it.
