Electronic Invoicing in Italy
Is e-invoicing mandatory in Italy ?
Yes, electronic invoicing has been mandatory for all domestic Italian invoices since January 2019. In April 2022, a law decree extended this obligation to so-called "minor taxpayers" through a gradual rollout beginning in July 2022.
Who is affected?
The mandate applies to all VAT-registered businesses—both resident and non-resident—operating in Italy. All are required to comply with the e-invoicing regulations.
Compliance requirements
Electronic invoices must be generated and submitted via a certified platform connected to the Italian central invoicing and reporting system, Sistema di Interscambio (SDI).
