Guest Reporting in Italy: How to Stay Compliant with Alloggiati Web and ISTAT in 2026
Guest reporting in Italy is required for all hosts, with deadlines as tight as 24 hours after check-in. You must send data to Alloggiati Web, file monthly ISTAT reports by region and collect tourist tax. In Trentino, homes with a CIPAT code also report through ISTAT Alloggi, using web service credentials from ISPAT. This guide covers every 2026 rule and how automation removes the manual work.
Key Takeaways
Guest reporting in Italy means all hosts must send guest data to Alloggiati Web within 24 hours of check-in. You must keep the receipts for at least 5 years.
ISTAT reporting is required across Italy but differs by region. In Trentino, private hosts with a CIPAT code must ask ISPAT for web service credentials to automate ISTAT Alloggi reports.
Tourist taxes in Italy are set by each municipality. They can vary by city, number of nights, guest age and property type, so each property needs its own setup.
Since 2026, Italian law requires ID checks for self check-in to happen when the guest arrives at the property. The check must start on-site, not rely only on uploaded documents.
Hosts who do not set up their Alloggiati Web credentials or regional ISTAT link risk fines. This is true even if they already use an online check-in platform.
What Italian hosts must report and to whom
Italy requires hosts to report guest data to two separate systems.
The first is Alloggiati Web, the national portal run by the Polizia di Stato. You must send guest data there within 24 hours of check-in.
The second is ISTAT, the national statistics institute. It gets data through regional systems that differ by property location. In Trentino, the platform is ISTAT Alloggi, run by the Autonomous Province of Trento.
ISTAT Alloggi applies only to private apartments and vacation homes with a CIPAT code. CIPAT stands for Codice Identificativo delle Strutture Ricettive, which the Province assigns at registration. Hotels, B&Bs and licensed hospitality businesses use a separate flow called STU, not this platform.
Hosts must also collect tourist taxes and pay them to their local municipality. Rates can vary by city, number of nights, guest age and property type.
Nearly all accommodation businesses in Italy must also send electronic invoices to the Italian Tax Authority through the Sistema di Interscambio.
Italian hosts usually need to manage duties such as:
Alloggiati Web guest reporting within 24 hours of check-in
ISTAT statistical reporting by the 5th of the following month
ISTAT Alloggi reporting via CIPAT code for private operators in Trentino (DTU flow)
Tourist tax collection and municipal reporting
Electronic invoicing via Sistema di Interscambio
Storage of submission receipts for 5 years
Identity verification for remote and self check-in scenarios
How ISTAT Alloggi works in Trentino and how to get credentials
In most of Italy, ISTAT reports go through regional portals with different formats and rules. Automation can cover about 90% of Italian territory.
Some regions, such as Puglia and Umbria, need a ready-to-upload file. The platform creates the file, and the host uploads it by hand once a month.
In Trentino, private hosts with a CIPAT code use ISTAT Alloggi. It offers three ways to send data. You can type data by hand on the DTU Trento portal after logging in with SPID, CPS, CNS or eIDAS. You can import a data file for the period. Or you can use a web service through accredited property management software.
Only the web service removes manual work fully. But it needs its own credentials from ISPAT, the provincial statistics office. These are separate from the SPID or CPS login you use for manual access.
To request them, download the Softwarehouse form from the Istat Alloggi – Materiale utenza page on the Province of Trento website. Fill it in, sign it and send it by certified email to [email protected].
If these credentials are not set up in the platform, the link cannot be validated. Automated reporting will not work, even if the rest of your check-in setup is active.
For Trentino hosts, getting and activating credentials usually involves steps such as:
Download the Softwarehouse form from the Istat Alloggi - Materiale utenza section of the Province of Trento website
Complete the form with operator details and a valid email address for communications
Receive Username and Password from ISPAT for web service activation
In ISTAT Alloggi, go to Import > Software, select your accredited provider, enter the relevant CIPAT codes, and click Update
Enter the ISPAT credentials in your platform's Statistics connection settings
Guest data is transmitted automatically to the Province after each check-in from that point forward
Identity verification requirements for remote check-in in 2026
Italian law on ID checks for self check-in changed a lot in 2026.
After a Council of State ruling in 2025, Italian authorities confirmed that check-in does not need staff on site. But it does need a visual ID check at the exact moment the guest arrives. Uploading documents before arrival is no longer enough.
The compliant method uses a QR code at the property entrance. When the guest arrives and scans it, a biometric ID check starts right at the door.
Access details, like door codes or smart lock access, are released only after the check succeeds. If a staff member meets guests in person, the ID check stays optional.
A compliant remote ID check workflow may include steps such as:
Guest arrives at property and scans QR code at entrance
Biometric identity verification triggered on-site
System confirms identity in real time
Smart lock or access code released only after verification
Guest reporting to Alloggiati Web triggered automatically
Submission receipt stored for legal traceability
Frequently Asked Questions
How do I get ISTAT Alloggi web service credentials in Trentino?
ISPAT, the Trento statistics office, issues the credentials on request. Get the Softwarehouse form from "Istat Alloggi - Materiale utenza" on the Province's website. Sign it and send it by certified email to [email protected]. Enter the Username and Password in your platform, and link your CIPAT codes to your provider in ISTAT Alloggi. Without this, automated reporting cannot be validated.
What is the difference between ISTAT Alloggi and Alloggiati Web in Italy?
They are two separate duties. Alloggiati Web is the national portal of the Polizia di Stato, where all hosts must send guest data within 24 hours of check-in. ISTAT Alloggi is a Trentino statistics platform for private homes with a CIPAT code. It uses the DTU flow, not the STU channel used by hotels and licensed B&Bs.
What is a CIPAT code and who needs one in Italy?
CIPAT stands for Codice Identificativo delle Strutture Ricettive. The Autonomous Province of Trento assigns this code when a private rental is registered. It applies to tourist apartments and vacation homes in Trentino and is needed for all provincial filings, including ISTAT Alloggi. Hosts outside Trentino do not use a CIPAT code and report through their own regional ISTAT portals.
What happens if guest data is not submitted to Alloggiati Web within 24 hours?
Missing the 24-hour deadline can lead to fines and possible inspections. If data was not sent on time, the advice is to send it by official certified email to the right authorities. Changing check-in dates to resend data is a common workaround, but it is not fully compliant.
Is ISTAT reporting the same across all Italian regions?
No. ISTAT reporting differs by region, with different portals, formats and rules based on property location. In Trentino, private hosts use ISTAT Alloggi with a CIPAT code and need web service credentials from ISPAT to automate it. For regions such as Puglia and Umbria, automation can create a ready-to-upload file that the host sends to the regional portal once a month.
