A guide to Italy’s B2B e-invoicing mandate

Country compliance and e-invoicing mandates can make it tricky for organisations to understand what’s expected of them and how to navigate the wealth of information available on the subject. Tungsten Network cuts through the complexity, addressing the most common issues related to the Italian B2B mandate and how we can help.


Why Italy has introduced the B2B mandate and what this means for you

Italy has one of the largest VAT gaps of any EU Member State, standing at a 35 Billion euros in 2015. In an effort to combat fraud and tax leakage, the Italian government has mandated a clearance model system as opposed to post audit.

If your organisation pays taxes in Italy and you send or receive invoices in Italy this applies to you.

This means all invoices must be submitted for registration, in a predefined Fattura XML format, through an online government portal, the Sistema di Interscambio (SdI), before becoming a legal tax document.

The deadline for the mandate came into effect on 1 January  2019 and the legislation is very clear about the consequences of non-compliance: if an invoice that is issued in any other way than electronically via the SdI in the Fattura XML format, it is not considered as issued, and therefore is subject to penalties (equal to 90 – 180% of the associated VAT dollar amount.)

This SdI process is mandatory for all B2B and B2C suppliers who are taxpaying entities in Italy

Get ahead of the deadline… choose Tungsten Network as
your Intermediary

As recognised experts in compliance we’ve become an intermediary for the Italian Government mandate on preclearance e-invoicing.

In practice this means we simply ‘punch out’ the e-invoice information (no paper, PDFs or EDI) from the AR department to the Sistema di Interscambio (SdI) in their chosen format (Fattura XML). Once processed, we then retrieve and deliver it to the AP department for payment.

A brief history and the Italian requirements:

  • B2G e-invoicing has been mandatory in the FatturaPA XML format since 2014
  • Invoices are transmitted through a government portal, the Sistema di Interscambio (SdI)
  • In 2016, the government also made the SdI available for B2B e-invoices, but adoption was limited
  • Fast forward to 2018, a Budget Bill was passed to make B2B e-invoicing mandatory for any organisation registered to pay tax in Italy
  • The deadline for compliance was January 1st 2019
  • All organisations must find an intermediary to pass the Fattura XML file (invoice payload) to the SdI before issuing to the recipient
  • Failure to invoice in this ‘pre-clearance’ way means the invoice is treated as if it was never issued
  • Those who fail to comply face a penalty potential of 90 – 180% of the associated VAT amount
