The CIN, the National Identification Code, is mandatory for every property used for short or tourist lets. It is requested on the Ministry of Tourism’s national accommodation database, must be displayed outside the property and quoted in every listing — on the manager’s site as on the portals. In Tuscany it has absorbed the earlier regional code, which is no longer used on its own. Without a CIN the fines are heavy and the portals remove the listing; it is the first thing we check when we take on a house.
The same law that introduced the CIN requires working combustible-gas and carbon-monoxide detectors in short-let properties, plus certified portable extinguishers in adequate number. These are the owner’s obligations, not the guest’s or the manager’s, but they need checking every season: an expired detector is the same as none.
Guest registration: within twenty-four hours of arrival — or on arrival, for shorter stays — the details of every guest must be sent to the police headquarters through the State Police’s Alloggiati Web portal. It is the obligation most often missed when someone else does the check-in: whoever welcomes the guests has to collect the documents, and someone has to transmit them that evening. That is one more reason our check-in is in person.
ISTAT: the Tuscany Region collects tourist flows every month — arrivals and overnight stays by nationality — through its own reporting system. Months with no guests must be reported too. It is not a tax, but failing to report is fined, and the data is how the region actually counts tourism in private homes.
The tourist tax is set by each municipality: amount per night, exemptions, maximum number of nights, periods of application. The owner collects it from the guest, pays it to the municipality on the set dates and files the return — now annual under national law, with local schedules on top. It must be shown as a separate item, never folded into the rate. On some portals the portal itself collects and remits it; the filing obligation remains.
How we handle it: CIN requested, displayed and quoted in every listing; detectors and extinguishers covered by the periodic property check; in-person check-in with documents transmitted within twenty-four hours; ISTAT and tourist tax on one calendar of deadlines, receipts in the monthly statement. The rules change — this guide is current as of September 2026 — and they change municipality by municipality: if you own a villa in Tuscany and are not sure you are compliant, write to us and we will tell you in one phone call.
