ROSS1000 ISTAT: practical 2026 guide for vacation rentals and short-term lets in Italy

ROSS1000 (Rilevazione sull'Offerta del Sistema Turistico Statistico — '1000 properties' edition) is the system through which Italian accommodations report tourist movement data (arrivals and overnights) to ISTAT, via the Regions and Autonomous Provinces. It is a mandatory statistical filing required by the National Statistical Programme (PSN) and the Italian Tourism Code, and applies also to non-professional short-term rentals.

In this practical guide we cover what ROSS1000 is, who must file it, what data is needed, monthly deadlines, fines and how to automate filing from your PMS — a critical topic for short-term-rental property managers.

What ROSS1000 is in practice

ROSS1000 is a national web application provided by Sviluppo Toscana on behalf of ISTAT, adopted by many Italian Regions (Tuscany, Liguria, Emilia-Romagna, Marche, Umbria, Calabria and others). Other Regions use equivalent systems (Turismo5 in Trentino-South Tyrol, Stat in Veneto, Roperin in Sardinia, etc.) but the principle is the same: every month the manager enters arrivals, overnights, origin and guest type for each day.

Who must file ROSS1000

The obligation covers every accommodation registered at regional level, including:

• Hotels, residences, hostels, agriturismi, B&Bs, guesthouses, hostels, refuges.
• Vacation houses and apartments (CAV), professional and non-professional.
• Tourist short-term rentals up to 30 days in many Regions (Tuscany, Liguria, etc.) — including private hosts with a single unit.
• Open-air facilities: campsites, tourist villages, marinas.

Check your Region's guidelines to see whether short-term rentals are included: in some Regions the statistical obligation kicks in only above a certain annual threshold or if you have a VAT number.

How to access ROSS1000

1. Verify on the regional tourism portal that your property has an active CIR (Regional Identification Code).
2. Request ROSS1000 credentials from your Region/Province (some issue them automatically with the CIR, others on request).
3. Log into the portal (in many Regions the URL is ross1000.regione.<code>.it) with username/password or SPID/CIE.
4. You'll find the property pre-loaded with master data from the SCIA / CIR.

What data you must report every day

• Number of arrivals (guests checking in that day).
• Number of overnights (sum of nights accrued by all guests already on site).
• Guest origin: foreign country or Italian province.
• Notes on extraordinary movements (groups, events).

Data is entered by calendar day. If you host a guest from May 15 for 4 nights, that's 1 arrival on the 15th and 1 overnight for each of the nights from the 15th to the 18th.

Monthly deadlines: the day-5 rule

In most Regions using ROSS1000, monthly data must be consolidated and submitted by the 5th day of the following month. Example: May data is closed by June 5. Some Regions enforce weekly or bi-weekly deadlines — always check your Region's resolution.

ROSS1000 lets you enter data daily, weekly or as a single end-of-month batch. Best practice is daily entry or, even better, automatic syncing from your PMS.

Fines for missed or incorrect ISTAT filings

Statistical-reporting fines are governed by D.Lgs. 322/1989 and regional acts. Typical amounts per missed monthly filing range from:

• €516 to €5,164 for liable individuals (D.Lgs. 322/89, art. 11).
• €1,032 to €10,329 for legal entities (companies, cooperatives, organisations).
• Additional regional sanctions for repeated delays and CIR/CIN suspension in the most serious cases.

Regions cross-check ROSS1000 with CIN, Alloggiati Web and municipal tourist tax: significant discrepancies between the three systems are the first audit trigger.

ROSS1000 vs Alloggiati Web vs tourist tax: three distinct flows

• Alloggiati Web (State Police): public-security report with personal data of every guest, within 24 hours of arrival.
• ROSS1000 (ISTAT/Region): aggregated statistical report of arrivals and overnights, by the 5th of the following month.
• Tourist tax (Municipality): payment of the tax due by the tourist, with municipal deadlines (typically quarterly).

The three flows are independent and all mandatory. You must file ROSS1000 even if you have already submitted Alloggiati Web and paid the tourist tax: data is not transferred between systems.

FAQ — frequently asked questions about ROSS1000

Do I need to declare months without guests?

Yes. Months with zero overnights must be declared as 'zero movement'. Failing to declare a zero month counts as a missed filing.

What if I notice an error after submission?

ROSS1000 lets you correct data even after the deadline, but repeated corrections are flagged. Better to close the month cleanly on first submission.

Should I register one unit per apartment or per building?

Each unit with a separate CIR has its own ROSS1000 record. Multiple apartments = multiple monthly filings.

Is ROSS1000 data public?

Aggregated data feeds public ISTAT tourism statistics, but per-property data is covered by statistical secrecy (D.Lgs. 322/89, art. 9).

How to automate ROSS1000 with a PMS

Manually entering arrivals and overnights for 20-50 units every month is one of the most time-consuming tasks for a property manager. The leading Italian PMSs (Krossbooking, Slope, Beddy, Octorate, Wubook) and several international PMSs (Smoobu, Lodgify, Avantio) integrate direct ROSS1000 transmission — and equivalent regional systems — via web service.

Optimal flow: the PMS receives bookings from OTAs, records check-ins, computes daily arrivals and overnights and transmits data to the regional portal automatically before the deadline. The host only verifies a monthly report.

HopySuite integrates with PMSs that handle ROSS1000 transmission and amplifies value on the conversational side: WhatsApp pre-check-in messages collect guest data and origin in a structured way, reducing the errors that generate discrepancies between Alloggiati Web and ROSS1000. The result is a complete, compliant and automated check-in in minutes.

Monthly checklist for ROSS1000 compliance

1. By the 1st of the month, verify that all properties are active in the regional portal.
2. Reconcile PMS data with Alloggiati Web and tourist tax: arrivals and nights must match.
3. Submit ROSS1000 data by day 5 (or per the regional deadline).
4. Save the transmission receipt as PDF and archive it with the CIR/CIN.
5. Note any extraordinary movements (groups, events, closures).

Conclusion

ROSS1000 is one of the three pillars of Italian short-term-rental compliance, alongside Alloggiati Web and CIN. Underestimating it means accumulating silent statistical fines that surface only during cross-checks. Automating it from your PMS, pairing it with a conversational workflow that collects clean guest data and keeping the three systems aligned is today the only way to scale beyond 10-15 units while staying fully compliant with limited operational hours.
