Agenzia delle Entrate Authentication

Connecting your tax account in Italy

To activate live taxation in Italy, you connect your OpenFiskal app with your Italian Revenue Agency account. This authorises OpenFiskal to handle your Italian tax account credentials on your behalf. This step is part of the Go-Live-Flow and must be completed before going live.

What is AdE authentication?

AdE stands for Agenzia delle Entrate, the Italian tax authority. During authentication:

• Enter your Fisconline credentials
• OpenFiskal establishes a secure connection
• The system can operate in compliance with Italian RT requirements

What credentials are required?

On the “Step 1: Revenue Agency Credentials” screen, you must enter:

• Fisconline password
• Fisconline PIN
• Tax code of the authorised person

These three elements establish authentication.

How do I get a Fisconline account?

If you do not yet have an account:

1. You must request one from the Revenue Agency. There is three ways to do this: Online via the AdE portal, in person at a local office, or via the AgenziaEntrate App.
2. Activation may require personal identification.
3. You will receive:

• The initial password immediately.
• The PIN at a later stage (immediate part + deferred part).

Please note: Credentials expire

Important feature in Italy: The Fisconline credentials used for this integration expire every 90 days. This means:

• They must be renewed periodically (Every 60 days is recommended).
• If they are not updated, authentication will be interrupted.
• Operational blocks may occur until renewal.

Appointments and Company Access

It is not mandatory for the Legal Representative to authenticate personally. They can appoint an employee or accountant as an Appointed Operator ("Gestore Incaricato"):

1. The Legal Representative logs into the AdE Area Riservata.
2. They navigate to "Il tuo profilo" → "Incarichi" → "Gestisci incarichi come rappresentante legale."
3. They enter the company's tax code, then select "Aggiungi gestore incaricato."
4. They enter the tax code of the Appointed Operator and confirm.
5. Once the appointment is active, the appointed person can request their own Fisconline credentials (if they don't already have them) and use those to authenticate in OpenFiskal.

Procedure in OpenFiskal

1. Enter your Fisconline password.
2. Enter your Fisconline PIN.
3. Enter your tax code.
4. Click on ‘Save credentials’.
5. Proceed with the Go-Live-Flow.

Once this step is complete, the system is authenticated and you can proceed with:

• Operating mode activation
• RT configuration
• Commissioning

What happens if authentication fails?

The most common causes:

• Incorrect PIN
• Expired password
• Credentials not renewed after 60 days
• Unauthorised tax code
• Delegation not active

In these cases:

• Check direct access to the Revenue Agency portal.
• Check the status of delegations.
• Renew credentials if necessary.

In summary

AdE authentication is the technical link between: OpenFiskal ↔ Revenue Agency

Without this step, you cannot go live. You need:

• Fisconline password
• PIN
• Authorised tax code
• Valid credentials (remember: 60-day expiry)
