The Agenzia delle Entrate portal

The AdE exposes a coherent set of online services around the SdI: a free invoice entry and consultation portal (Fatture e Corrispettivi), a taxpayer-side fiscal dashboard (Stanza del Contribuente), the integrated tax payment F24, the SDIcoop cooperative API for accredited intermediaries, and the B2G registry IndicePA for public entities.

Fatture e Corrispettivi

The flagship service offered free by the AdE since 2019. Covers the full invoice lifecycle for taxpayers without an ERP or commercial intermediary.

• Manual entry of a PA or PR fattura via a guided form, automatic generation of FPR12-compliant XML.
• XML upload pre-generated by an ERP, server-side XSD checks before sending to the SdI.
• Consultation of invoices received and sent over the last 18 months (free for viewing only, no legal conservazione sostitutiva).
• Notifiche — ricevute (RC, NS, MC, EC) delivered to a dedicated inbox, CSV export.
• Corrispettivi telematici — section dedicated to B2C transactions transmitted by certified cash registers (RT — Registratori Telematici).
• Delegation to an intermediary — option allowing a commercialista to manage the account on the taxpayer's behalf.

Stanza del Contribuente

Personal Italian taxpayer dashboard, giving a unified view of fiscal obligations and interactions with the AdE.

• Pre-filled returns (modello 730 for employees, modello Redditi PF for self-employed).
• Global fiscal situation (taxes paid, upcoming deadlines, received communications).
• Cassetto Fiscale — official archive of all fiscal documents issued by the AdE for the taxpayer.
• Digital domicile of the taxpayer (digital domicile per Art. 3-bis CAD).
• Declared notification channel preference (PEC vs portal), usable by public authorities.

F24 — integrated tax payment

The Modello F24 is the unique electronic form for tax payment in Italy. It allows offsetting between credits and debits across several tax types (IVA, IRPEF, IRES, IRAP, INPS, INAIL, local taxes).

• F24 Ordinario — for individual taxpayers, filed via Fatture e Corrispettivi or directly via Entratel/Fisconline.
• F24 EP (Enti Pubblici) — for public entities, covering social contributions, withholdings and other transfers to the State.
• F24 Accise — excise duties on energy, alcohol, tobacco.
• F24 Elide — for rare codici-tributo (registration of tenancy contracts, registration duties).
• XML format — F24 schema v2.0, CAdES-BES electronic signature required for transmission via Entratel.

SDIcoop — cooperative API

Programmatic interface for accredited intermediaries to interact machine-to-machine with the SdI. Distinct from the Fatture e Corrispettivi portal.

• SOAP 1.2 — historical endpoint, WSDL published by the AdE, operations RiceviFatture, RiceviNotifiche, RicercaFatture.
• REST API (V2 since 2022) — JSON, OpenAPI 3.0 published, simpler to integrate for modern ERPs.
• mTLS authentication — qualified SSL/TLS certificate installed at the intermediary, key pair registered with the SdI during accreditation.
• Throughput limits — 60 requests/min nominal, burst up to 300/min for 5 min; beyond that, HTTP 429 throttling.
• Webhook notifiche — the AdE pushes ricevute to an HTTPS URL declared by the intermediary (configuration mandatory since 2023).

Detailed documentation of operations, schemas and examples in the dedicated SDIcoop page.

IndicePA — B2G registry

IndicePA (www.indicepa.gov.it) is the official registry of Italian public entities for electronic B2G. It lists more than 22,000 bodies: ministries, local authorities, schools, hospitals, ASLs, fiscal agencies, ENPALS, INPS, INAIL, etc.

• Codice IPA — 6-7 character identifier of each public entity. Format UFXXXX or similar.
• Codice Univoco Ufficio (CUF) — service-level sub-identifier within an entity, required for routing PA invoices (FPA12) to the correct receiving desk. 6-character alphanumeric format.
• REST API — IndicePA exposes a REST API allowing ERPs to verify the existence and conformity of a CUF before sending a B2G invoice.
• Synchronisation — base updated daily, 24h cache recommended on the integrator side.
• FatturaPA B2G (FPA12) — systematically uses the CUF in CodiceDestinatario, not an intermediary CD.
