What is SDI?

All electronic invoices in Italy must be sent to Sistema di Interscambio.

SDI is a national online hub, which serves as an address to the corresponding government department.

What is required?

Italy uses the CTC (continuous transaction controls) system for e-invoices and the FatturaXML format for accounts payable and accounts receivable. Under the CTC SDI model, companies issue structured invoices in the tax authorities’ XML schema format, called FatturaPA. In B2G transactions, companies are obliged to issue a qualified electronic signature. This can be done by them or by a service provider. In the public healthcare sector, there is an additional flow of electronic orders via the NSO, which functions in the same way as the SDI. 

Who is obliged to use e-invoicing in Italy?

Electronic invoicing in Italy has been obligatory in B2G for all central administrations since 2014, with the implementation of European Directive 2014/55/EU, followed by fully being obligatory for the B2G sector the next year and B2B and B2C in 2019.

    Key benefits icon


    The Italian government is very strict with its e-invoicing system, and has applied a set of penalties for users: 

    • Wrong XML format invoice can result in between 90% and 180% of VAT amount penalty
    • Sending a wrong invoice to a client will amount in a penalty equal to 100% of VAT 

    From 1st of July, all Italian companies have been obliged to communicate cross-border invoices. There is an administrative penalty from EUR 2 to EUR 400 for each invoice not communicated correctly. However, if the invoice is issued and corrected within 15 days, the penalty is halved.

    The future of e-invoicing in Italy

    Being one of the pioneers in Europe for e-invoicing, Italy is always working to provide new regulations in order to ensure all sectors and users are covered. For example, from January 2024, microenterprises with revenue or fees of EUR 25,000 will be obliged to send electronic invoices to the SDI. The government and tax authorities regularly update technical specifications in order to further improve e-invoicing processes, thus maintaining Italy’s strong position in e-invoicing with a robust compliance model and system.
