Identification of persons and entities

The Web Companies help service does not support the submission of returns with persons or entities misidentified ( NIF of partners, administrators, investee entities, etc.).

Therefore, it is recommended to use the identification help service in advance, which is available on the AEAT website, where you can consult the identification both individually and in bulk.

In those cases in which completion of identification data from third countries is possible (using a country field or mark similar to this purpose), validation against the AEAT census will not be carried out.
