Short-term rental rules in Italy

Request the CIN for each property on the Ministry of Tourism's BDSR portal. Show it in every online listing and on a sign outside the building. Operating without it can be fined €800 to €8,000.

Some regions also issue their own code (such as CIR in Lombardy or CITRA in Liguria). Where they do, you may need to show both.

If you run short-term rentals as a business, you also need to file a SCIA (certified start-of-activity notice) with your comune.

Some cities restrict new short-term rentals in historic centres (Florence, for example) or ban key boxes on the street. Check your comune's rules before you start.

Send every guest's ID details to the police through the Alloggiati Web portal within 24 hours of arrival (within 6 hours for stays shorter than a day). The rules on identifying guests remotely have changed with recent court rulings, so check the current guidance.

Most regions also ask you to send guest statistics, usually through a regional portal.

Every unit must have working detectors for flammable gas and carbon monoxide and a portable fire extinguisher, placed where guests can reach them.

Private hosts can choose a flat tax instead of normal income tax: 21% on one short-term rental property and 26% on the second. When a platform collects the payment, it withholds part of the tax upfront.

From 2026, letting three or more apartments short-term in the same year is treated as a business: you need a VAT number (partita IVA) and INPS registration, and the flat tax no longer applies.

Many comuni charge an imposta di soggiorno per person per night. Collect it and pay it to the comune; in some cities the platform collects it for you.

Since 20 May 2026, platforms must check that listings show a valid registration number (the CIN, in Italy) and share booking data with the authorities.
