Italy

In Italy, fiskaly supports sending B2B e-invoices. E-invoicing is mandatory and regulated by the Agenzia delle Entrate (Revenue Agency). All B2B invoices must be exchanged via SDI (Sistema di Interscambio — Exchange System) in the FatturaPA (Electronic Invoice) XML format and have been legally required since January 2019.

fiskaly generates FatturaPA e-invoices and submits them to SDI for delivery. SDI validates and forwards the invoice to the recipient asynchronously — no network registration is required.

This page covers the Italy-specific requirements that complement the General Step-by-Step Integration, for onboarding a Taxpayer for e-invoicing.

💡Already using SIGN IT?

If you already have a SIGN IT integration, you don’t start from scratch — you extend your existing Taxpayer with the additional registration data and commission an E_INVOICE_SERVICE System. See E-INVOICE IT for SIGN IT customers for the full steps.

Make sure you have the following Taxpayer information ready before proceeding.

Italy-specific registration data — submitted under content.fiscalization.registration:

company_id — Numero Registro Imprese (Business Register number)
office — province code of the Camera di Commercio that issued the REA number, e.g. MI, RM
entry — REA number (6 or 7 digits)
legal_form — legal form of the entity (e.g. LIMITED_LIABILITY_COMPANY, JOINT_STOCK_COMPANY)
capital — registered share capital in EUR (e.g. "10000.00")
shareholder_status — SOLE_SHAREHOLDER or MULTIPLE_SHAREHOLDERS
liquidation_status — IN_LIQUIDATION or NOT_IN_LIQUIDATION
tax_regime — optional, ORDINARY (default) or FLAT_RATE_SCHEME (Regime Forfettario)

Standard Taxpayer fields — part of the Taxpayer itself (shared with SIGN IT if you use it):

content.name — registered legal name of the company or individual
content.address — registered legal address
content.address.region — Provincia (Province code, e.g. MI, RM); mandatory for SDI submission

📘Region is required for E-INVOICE

For e-invoicing in Italy, content.address.region (Provincia) is a required field on the Taxpayer. It is validated when the E_INVOICE_SERVICE System is commissioned — if the region is missing, commissioning fails. Make sure it is set or updated on the Taxpayer beforehand.

Recipient requirements

As described in the General Step-by-Step Integration, the recipient of an e-invoice is required to be a BUSINESS type and the invoicing block is required to be populated. For Italy, this means:

setting invoicing.type = SDI
providing a destination_code

Scenario	`destination_code`	`pec`
Recipient has a registered SDI inbox	7-char alphanumeric (e.g. `ABC1234`)	optional
Recipient is not registered with SDI	`"0000000"`	required
Recipient is outside Italy	`"XXXXXXX"`	not used

⚠️PEC required for unregistered recipients

Submitting destination_code = "0000000" without a pec address will fail before the invoice reaches SDI. Only B2B recipients are supported — B2C invoices are out of scope.
