A sparkling jewel of Italy, Lake Como draws visitors from around the world, but renting out a property here involves more than just handing over the keys and wishing guests “buona vacanza.” Property owners must navigate a maze of new compliance rules, especially since 2024, when Italy introduced the National Identification Code (CIN) for short-term rentals. The CIN, automatically assigned by the Italian Ministry of Tourism, instantly became the hottest accessory for every rental in Lake Como.
It isn’t just for show—each property must display this code at its entrance and include it in every advertisement, from glossy online listings to the simplest flyers. Forgetting or skipping this vital detail can cost dearly, with fines ranging from €500 to €5,000, which is more than the price of a luxury dinner for ten on the lakefront.
Obtaining the CIN requires registration through the Turismo5 online portal. Only after approval can a property owner begin renting legally. This code acts as a unique fingerprint, ensuring every short-term rental is tracked and accounted for across Italy. While the CIN grabs the spotlight, it is only one piece of the compliance puzzle.
The CIN is your property’s unique fingerprint—register through Turismo5 and unlock the legal path to renting in Lake Como.
Another important code, the CIR, must also be displayed on all listings and advertisements. Missing these details can turn a property owner’s dream of easy rental income into a bureaucratic headache. Hosts must also collect and remit a tourist tax, which varies by season and guest number, and this tourist tax compliance is strictly enforced by local authorities.]
Starting in 2026, the rules get even tighter. The government will reduce the maximum number of apartments an individual can rent under the non-business, flat-rate tax regime from four to two. The first property gets a 21% flat tax rate, the second jumps to 26%, and if someone rents out more than two apartments, the activity is classified as a business, requiring VAT registration and a host of additional obligations.
This rule only applies to contracts of 30 days or less, so longer-term leases are counted differently.
The compliance journey does not end there. In Lombardy, which includes Lake Como, every short-term rental host must submit a SCIA declaration through the Impresa in un Giorno website before starting operations. After this, hosts must visit the local police headquarters to gain access to the Allogiati Web portal, where guest details are registered within 24 hours of arrival.
Safety standards are strict, and only basic services such as cleaning and linen provision are permitted unless the owner is registered as a business. While the process may seem overwhelming, it helps keep Lake Como a sparkling and safe haven for both guests and hosts.
