Communication to Suppliers 

Starting from March 31, 2015,  in compliance with law n. 244 of 24 December 2007 and the Legislative Decree. n. 66/2014, converted with amendments by law 23 June 2014 n. 89, the obligation of electronic invoicing in relations with the Public Administration comes into force. With the ministerial decree n. 55 of 3 April 2013 and the related annexes, available on the website InvoicePa (link in the External Links section) the methods for forming, issuing and transmitting the electronic invoice to the Public Administrations have been defined.

In compliance with current provisions, this body has identified the offices responsible for receiving electronic invoices, which can be downloaded in the attachment, and published them on the Index of Public Administrations website.

Each office receiving electronic invoicing is characterized by a Unique Code which must be indicated in the electronic invoice layout in section 1.1.4 Recipient Code. 

The invoices must also necessarily include, if validated, the Tender Identification Code (CIG) and the Single Project Code (CUP) communicated by the Administration to the supplier. Failure to indicate these codes prevents the organization from proceeding with the payment of the invoices. 

In order to correctly address the invoices to the competent offices for settlement, it is also required to indicate, in section 1.2.6 Administration Reference of the route, the internal code that identifies the management or sector/service responsible for the order or contract. These codes, for contracts in place as of January 2015, XNUMX, were communicated to interested parties by email. Contracts stipulated after this date will be the subject of new communications, together with the Univocal Office Code and CIG and CUP.

If the communication of the codes referred to in the previous points has not been received, please report it by e-mail to the inbox Bil.infofatturaelettronica@comune.milano.it.

Please also remember that the following elements must be indicated in the electronic invoice, although they do not constitute mandatory fields in the FatturaPA layout:

• contractual or order references, to be indicated in block 2.1.2 or block 2.1.3
• payment due date
• withholding tax of 0.5% foreseen by the Presidential Decree. n. 207/2010
• spending commitment if communicated by the Administration: in section 2.2.1.16.1 it is necessary to indicate "commitment" and in section 2.2.1.16.2 indicate the commitment number in the format communicated.

Finally, we would like to remind you that starting from January 2015, 17, transactions carried out with Public Administrations are subject to the payment split regime referred to in art. 633-ter Presidential Decree 1972/2.2.2. In section XNUMX Summary data on the invoice it is therefore necessary to indicate the code "S" which expresses this method of VAT payment in addition to the relevant regulatory reference.
