- A new web service is available from January 27, 2026, on the “Fatture e Corrispettivi” portal to integrate the Codice Unico di Progetto (CUP) into electronic invoices related to publicly incentivized purchases.
- Buyers or their intermediaries can add or correct the CUP in invoices if it was missing or incorrect and not properly reissued by the seller.
- The service allows users to view, insert, or delete CUPs for invoices issued from June 1, 2023, onwards, specifying if the CUP applies to the whole invoice or a single line.
- Once a CUP is included by the seller at issuance, it cannot be changed, but corrections can be made using the new service.
- The Italian Revenue Agency has published a guide on its website for using these new features.
