"Titular del certificado no consta como asociación activa"
The error "The certificate holder is not listed as an active association" pops up when accessing the formality "Registration of collegiate bodies and associations" in "Social partnership", with a certificate that does not correspond to any association or college that the Tax Agency has a signed agreement with.
If being accessed by a social partner, remember that the proper option in this case is "Registration and management in the social partners register".
If being accessed by a collegiate body or association, make sure they have a signed agreement.If it is not, you can request it from the Tax Agency in writing, specifying the complete identification details of the entity (professional association) and the person who will be acting in representation thereof in the signing of the agreement, the territorial scope of the entity's activity and a description of the activities conducted.Then you can add the collegiate bodies from "Upload from register".To add more associations at a later date, go to "Register collegiate bodies/associations".
