E-invoicing in Italy

In force

B2B e-invoicing mandatory since 2019 — the oldest mandate in the EU.

Timeline

1 Jan 2019	B2B and B2C e-invoicing mandatory via SdI
1 Jul 2022	Extended to flat-rate taxpayers

What you have to send

Format: FatturaPA XML
Transmission: Sistema di Interscambio (SdI)

Italy uses its own FatturaPA schema through SdI, not EN 16931 directly. Cross-border invoices into Italy from EN 16931 systems are the usual conversion pain point.
