Compulsory eletronic invoice B2B and B2C

From the normative aspects to reorganization of documental procedures

What is the electronic invoice?

The electronic invoice is a digital system ofemission, transmission and filing of invoices that allows us toabandon the use of paper and all the resulting print, sending and filing costs.

The new format that electronic invoices need to be manufactured, transmitted, archived and preserved is a digital format called XML (eXtensible Markup Language), a computer language that allows us to define and control the meaning of the elements that are in the document, checking the information so to be in line with the legal procedures.

We make available to our clients the material and the presentations regarding the meeting of the 1st of October about the electronic invoice and other useful documents to best deal with this change!

Let’s clarify some things

When will the electronic invoice begin to be compulsory?

From the 1st of january 2019 the electronic invoice (e-invoice) has become compulsary not only for operations with the public administration, but also foroperations between parties with VAT, wheter they may be people or firms (B2B), and for operations with parties without VAT (B2C). However, there are many important exceptions.

Who is not included in the compulsory use of the electronic invoice?

The electronic invoice is not compulsory for the so-called “minimum” taxpayers (also called “advantaged”. comm 1 and 2, art 27, decreto legge 98/2011) and for the so-called “flat-rated” (comm 54-89, art 1, legge 190/2014, legge di stabilità 2015), who can receive them.

Can I invoice a subject (firm or natural person) not resident in Italy with the e-invoice?
Right now it is not allowed. However, for the operations with foreign countries there is the compulsory communication of data, according to the new rule called “esterometro”.
If a subject excluded from the compulsory e-invoice is asked for it, is it obliged to make it?
No, even though it could.
When we start using the e-invoice, do we stop with the paper version?
They do not have to be issued anymore, except for the subject excluded from the compulsory e-invoice. However, the consumer can ask for the paper version of the invoice in the personal website area of the Agenzia delle Entrate.
Can a subject obliged to use the e-invoice design a professional to make and archive the e-invoices?
Yes, it is possible to designate a financial services licensed professional. Who decides to designate a professional can do so online or through the informatic systems of the Agenzia delle Entrate (Entratel/Fisconline) or presenting a form in a local office of the Agenzia delle Entrate.
Does the e-invoice modify the leght of time of registrations or VAT deposit?
No. E-invoices must be sent to the Sistema di Interscambio (Sdi) of the Agenzia delle Entrate, which becomes the reference of registrations and deposits. The terms of submitting the documents remain the ones already issued (moment of actualization of the operation and moment of payment of the tax).
When is an e-invoice considered to be sent?

The e-invoice is considered issued on the day that is written on the e-invoice itself. The date written in the e-invoice has to match the moment of the operation, event though the actual issuing to the Sistema di Interscambio (Sdi) may not be at the same time, but it has to be done in 24 hours from the date of the operation even though they will be accepted, in a first phase, the ones sent with “minimum delay”.

If the e-invoice gets rejected, what can I do about it?
If the e-invoice is rejected from the Sistema di Interscambio Sdi, the system sends over a message of rejection within five days from the dispatch. At that stage, the invoice is considered not emitted and the sender can: proceed (within 5 days from the rejection communication) to a new emission of the invoice, with the same date and number; or (wheter the first solution may result not applicable) send a document with a new number and date “269/5000 for which a connection to the previous invoice rejected by Sdi is shown and subsequently reversed with internal accounting variation (without transmission to SdI) in order to make the invoice’s timeliness clear with respect to the operation it documents”. Not to come across possible mistakes in periodic VAT payments, it is better to transmit the invoice to the System Sdi within 5 days before the end of the month or trimester.
