A Taxpayer (formerly “Entity”) provides a particular Organization UNIT  (formerly “Asset UNIT”) with the relevant taxpayer data, and consists of two main parts:

Taxpayer information (type: COMPANY / INDIVIDUAL, name and address), and

Country-specific fiscalization details (fiscalization). For Italy, these include:

• The business tax id number (Codice Fiscale) and vat id number (Partita IVA), and 

• The tax identification number and Fisconline credentials of the authorized user — i.e., the individual who is entitled to operate on behalf of the business and holds Fisconline credentials.
