Italy's FatturaPA specifications v1.9 add TD29 and RF20, usable from 1 April 2025

What changed in detail

The Agenzia delle Entrate published version 1.9 of the technical specifications for FatturaPA electronic invoices and the Sistema di Interscambio (SdI). Allegato A, the technical specifications document, was updated on 31 January 2025, and the agency’s page states that the documentation is usable from 1 April 2025.

Version 1.9 makes these changes:

• a new document type, TD29, for the buyer’s (cessionario or committente) communication to the Agenzia delle Entrate that a supplier has failed to invoice, or has invoiced irregularly, under article 6, comma 8, of D.Lgs. 471/1997;
• a new tax-regime code, RF20, for the EU cross-border VAT franchise scheme of Directive (EU) 2020/285, implemented in Italy by D.Lgs. 180/2024;
• in SdI check 00460, removal of the EUR 400 total limit on simplified invoices issued by forfettario or franchise-scheme suppliers;
• revised SdI checks 00404 and 00409, and updated product codes for fuel.

What it means

Version 1.9 put into the invoice format two legal changes that already existed. Buyers who used to report a supplier’s missing or irregular invoice outside the SdI flow can file it as a TD29 document. Small suppliers using the EU franchise can identify themselves with RF20 (record). The agency’s page says “utilizzabile” (usable), not mandatory.

Version 1.9 is no longer the latest. The agency has since published version 1.9.1, usable from 15 May 2026. Its changes are technical maintenance, such as a new check for VAT-group tax codes and accreditation procedures, and add no new document type. The TD29 and RF20 codes from v1.9 remain part of the format.
