Ross1000 explained: who must send ISTAT guest data in Italy, and the rules region by region (2026)

What is Ross1000 and what is it for?

Every month ISTAT publishes statistics on guest movements in accommodation: how many guests arrive, how many nights they stay, where they come from. ISTAT doesn’t collect those figures directly. The Regions do, acting as intermediate collection bodies, and they ask everyone who hosts guests to report the data through a portal.

Ross1000 is the portal several Regions use for this, presented as the “Osservatorio Digitale del Turismo” (digital tourism observatory). You record arrivals and departures, the system calculates arrivi (arrivals) and presenze (nights spent), and the Region sends ISTAT the data in aggregate form. In some regions Ross1000 also handles other communications, such as opening and closing periods or the registration of tourist landlords.

Ross1000 region by region

There’s no single national portal: each Region decides who must report, on which portal and by when. The table sums up the rules we checked on the official websites.

L.R. means legge regionale, a regional law. What really changes from one region to another, in short:

• Lazio: the duty covers accommodation businesses and anyone offering hospitality in homes for tourist use. After registering on Ross 1000-Lazio you can fill in ISTAT form C/59 by hand or import an XML file from your property software. On the deadline, the regional page on art. 28 of L.R. 13/2007 speaks of sending within the month after arrival, while the April 2026 guidelines say by the 5th of the following month: to be safe, work to the 5th.
• Piedmont: when you register a tourist let you receive the Piemonte Dati Turismo credentials by email, and the data goes to the Province or Metropolitan City.
• Lombardy: you log in with SPID, CIE or CNS (Italy’s digital identity, electronic ID card and national services card), and the duty also covers anyone letting for tourist purposes, with fines of €250 to €2,500 for each month missed or incomplete.
• Veneto: the Region uses Ross1000 both for tourism statistics and for the duties of tourist landlords.
• Emilia-Romagna: access with SPID, CIE or CNS comes after the Region’s activation email, and you must also declare months with zero movement.
• Sardinia: tourism data is also collected through Ross1000; check access and deadlines on the Region’s portal.
• Liguria: since 1 April 2025 the duty covers every furnished apartment let for tourist use, with access to Ross1000 through SPID, CIE or CNS.
• Calabria: arrivals and nights flow into the Region’s Tourism and Mobility Observatory, which publishes them alongside other sources.
• Marche: the Istrice-Ross1000 portal belongs to the regional tourism observatory, and the duty also covers apartments let for tourist use.
• Abruzzo: since 2026 landlords register their lets with the Region’s Modulo Locazioni and then manage them on Ross1000.

Turismo5 (Tuscany)

In the provinces of Florence, Pistoia and Prato the data goes to Turismo5, not Ross1000. For the Metropolitan City of Florence, accommodation businesses, agriturismi (farm stays) and tourist lets must enter guest movements in real time with the Check in function; when you start, the statistics office gives you a code beginning with FI to create your credentials. Turismo5 can also prepare the police registrations and calculate the tourist tax. In Pistoia and Prato, check the instructions on your Province’s website.

Who must send the data?

The duty always covers accommodation businesses, hotel and non-hotel: hotels, B&Bs, affittacamere (rooms to let), case vacanze (holiday homes) and campsites. In many regions it also covers tourist lets and short-term rentals run by private individuals: that’s the case in Lazio, Lombardy and Marche, while Liguria and Emilia-Romagna expressly include furnished apartments let for tourist use. In Piedmont, anyone starting a non-business tourist let receives the credentials to report guest flows right after registering.

If your Region isn’t in the table, look on the regional website for the tourism observatory page (in Liguria and Marche it’s called exactly that, osservatorio turistico) or the statistics office: there you’ll find who must report, which portal to use and how to get credentials. If you’re starting from scratch, how to start a short-term rental in Italy shows where this step fits, and the guide to opening a B&B in Italy covers guesthouses.

What data do you send?

• Arrivals: how many guests arrived, and on which day.
• Nights: the nights guests spent in the property.
• Origin: for Italian residents, their Comune (municipality) of residence; for foreign guests, their country.
• Availability: rooms or beds occupied, days open, temporary closures.
• Zero movement: even in months without guests you must declare that there were no arrivals, or that the property was closed.

Some regional portals ask for extra information about guests, such as the booking channel or means of transport. Check which fields are mandatory in your Region.

How does reporting work, step by step?

1. 01

   Get access

   Once your activity has started (through the Comune’s business desk, the SUAP, or a notice to the Comune, depending on regional rules), the Region enables you on the portal. In Lombardy, Emilia-Romagna, Liguria and Marche you log in with SPID, CIE or CNS; in Piedmont credentials arrive by email after registration; in Lazio you register on the Ross 1000-Lazio platform.

2. 02

   Set up the property

   Check the property’s details, number of rooms and beds, and opening periods. In Lombardy the property profile also shows the CIR, the regional code you need to obtain the national CIN.

3. 03

   Record arrivals and departures

   You can enter each guest by hand or import a file from your property software: many Ross1000 portals accept TXT or XML files. The Regions recommend doing it every day.

4. 04

   Close the month by the deadline

   Check that every day is filled in, declare any days without movement or closures, and confirm by your Region’s deadline.

If you live abroad, logins can be the practical hurdle: SPID, CIE and CNS are Italian credentials, while Piedmont and Lazio work with a username and password. Ask your Region which access routes it accepts, or let a local manager or an automated service handle the monthly reporting with the property’s credentials.

Ross1000 vs Alloggiati Web: what’s the difference?

What they share is where the data comes from: the same guests, with the same dates. Typing them twice into two different portals is the quickest way to create inconsistencies, and since 20 May 2026 platforms also send the authorities the nights booked and the number of guests under the EU short-term rental regulation. For every duty that comes with a stay, see our guide to Italy’s short-term rental law.

How do you automate Ross1000 with Maurice?

With automatic Ross1000 and ISTAT reporting, Maurice sends the data to your region’s portal automatically, without manual logins: you enter the property’s credentials once, and guest movements go out from the data collected at online check-in. The portals it works with today:

• Ross1000 and related portals in Lazio, Piedmont, Lombardy, Veneto, Emilia-Romagna, Sardinia, Liguria, Calabria and Abruzzo;
• Istrice-Ross1000 in Marche;
• Turismo5 in Tuscany, for the provinces of Florence, Pistoia and Prato.

Campania is coming soon. Is your region missing? Contact the Maurice team and we’ll check the portal it uses with you. The same data feeds Alloggiati Web automation, and the regional portal is always available to you to check what was sent.
