Einvoice details on Tax invoice

This discussion clarifies whether specific e-invoice details, such as the IRN, QR code, and acknowledgement number, are mandatory on tax invoices under GST. While initial queries suggested it wasn't explicitly stated as mandatory in all e-invoice rules, it was confirmed that Rule 46(r) of the CGST Rules makes printing the QR code and IRN compulsory if an e-invoice has been generated. Furthermore, FAQs clarify that the QR code cannot be printed on a separate sheet.
