All registered companies in Italy are required to submit annual financial reports in XBRL format to the Italian Chambers of Commerce through the InfoCamere portal. The companies are required to use XBRL elements from the Italian GAAP taxonomy to tag their financial data and convert it into the digital format.
To comply with the Chamber of Commerce XBRL mandate, Italian companies need to tag the numbers in their financial statements and block-tag the notes to accounts.
The Italian GAAP taxonomy supports a fixed set of financial disclosures. Companies may leave untagged any information for which there is no available taxonomy element.
