E-invoicing in Italy

Live Confidence: high Checked 21 Jul 2026
ModelClearance · SdI (Sistema di Interscambio)
Required formatFatturaPA XML (schema 1.2.x; technical specs v1.9.1)
TimelineSince 2019

Who is in scope

B2G + B2B + B2C. All VAT-registered persons established in Italy, no turnover threshold since 1 Jan 2024 (includes forfettari). Non-established/non-resident businesses are NOT obliged to issue via SdI (they may opt in); their transactions are captured through the resident counterparty's cross-border TD reporting. B2C healthcare services are excluded by law.

Key dates

  • 31 Mar 2015 B2G e-invoicing via SdI mandatory for all public administrations (D.M. 55/2013).
  • 1 Jan 2019 B2B and B2C e-invoicing via SdI mandatory for all Italian-established VAT taxpayers (Law 205/2017 / DL 119/2018), above a turnover floor.
  • 1 Jul 2022 Cross-border transaction data (ex-'esterometro') moved onto SdI using FatturaPA TD-type documents.
  • 1 Jan 2024 Turnover-based exclusion removed entirely — flat-rate (forfettari) and minimi taxpayers fully in scope. No thresholds remain.
  • 1 Jan 2025 Permanent prohibition on sending B2C healthcare invoices through SdI (patient-confidentiality carve-out), made definitive rather than annually renewed.
  • 15 May 2026 FatturaPA technical specifications v1.9.1 usable from this date (successor to v1.9, in force 1 Apr 2025, which added TD29 and RF20 cross-border exemption regime).
  • 31 Dec 2027 EU derogation authorising mandatory e-invoicing expires (Council Implementing Decision (EU) 2024/3150 of 10 Dec 2024). Renewal or ViDA transition required.
What practitioners get burned by

Two traps. (1) The EU derogation runs out on 31 Dec 2027 — Italy must renew it or fold SdI into the ViDA framework; anyone writing a multi-year roadmap should not assume SdI is permanent in its current form. (2) FatturaPA is NOT natively EN 16931 — it is a national XML with an Italian CIUS, so cross-border ViDA alignment will require change. Also note the technical specs are a moving target (v1.9 from 1 Apr 2025 added TD29/RF20; v1.9.1 from 15 May 2026) — a 'live since 2019' framing hides real annual integration work.
