A mandatory National Identification Code, new tax thresholds, greater powers for municipalities and EU transparency requirements for online platforms: the short-term rental sector is entering the most heavily regulated phase in its history, with direct consequences for hosts, property managers and travel agencies.
For anyone managing short-term rentals in Italy, 2026 represents an unprecedented regulatory turning point. Over the past two years, lawmakers have developed a framework covering taxation, business classification, administrative obligations and property traceability.
The result is a much more tightly regulated sector, in which every booking now involves a series of compliance requirements concerning several different public authorities.
At the heart of this reorganisation is the National Identification Code, known in Italy as the CIN, introduced by Law No. 191/2023. This unique code identifies each individual property used for tourist accommodation or short-term rentals.
It replaces the previous regional identification codes and feeds into a single national database of accommodation facilities, the Banca Dati delle Strutture Ricettive (BDSR), managed by the Italian Ministry of Tourism.
From 2026, no property may be advertised or rented for tourism purposes without a valid CIN. The code must appear in every listing and must also be displayed outside the building. Failure to comply may result in fines of up to €8,000.
The Boundary Between Private Activity and Business Operations
One of the most significant changes concerns the distinction between private rental activity and commercial business operations. The 2026 Budget Law consolidates the applicable thresholds. Italy’s substitute tax regime for rental income, known as the cedolare secca, applies at a rate of 21% to one property selected by the taxpayer, while a 26% rate applies to any additional properties. The most important change, however, concerns the number of units being rented. From the third apartment used for short-term rentals during the same year, the activity is presumed to constitute a business. This triggers the obligation to obtain a VAT number, submit a Certified Notification of Business Activity, known as a SCIA, and register with the Italian Business Register. This change redefines the status of many operators and encourages the further professionalisation of the sector. Other obligations remain applicable regardless of the chosen tax regime. These include coordinating compliance across the CIN system, SCIA procedures, regional tourism portals, the police accommodation-registration platform Alloggiati Web, ISTAT statistical reporting and the collection and payment of local tourist taxes.
Municipal Powers and EU Regulation
The regulatory framework becomes even more complex at local level, where municipalities have acquired new urban-planning and regulatory powers. Although there is no nationwide ban on short-term rentals, several cities have introduced specific restrictions. Florence has prohibited new short-term rental properties within its UNESCO-listed area, while Milan has regulated the use of public land. Regarding remote check-in procedures, Italy’s Council of State has required guests to undergo real-time visual identification, calling into question the widespread use of unattended key boxes. At European level, two measures are increasing the traceability of rental activity. The DAC7 Directive requires platforms such as Airbnb, Booking.com and Vrbo to automatically transmit information on each host to the Italian Revenue Agency. This includes the host’s identity, tax identification number, number of nights rented and income received. The EU regulation on short-term rental transparency, applicable from 20 May 2026, also requires platforms to verify registration codes, periodically transmit data to the relevant authorities and remove non-compliant listings.
A Sector Undergoing a Structural Transformation
Taken together, these measures have a clearly stated objective: to reduce undeclared activity and provide greater transparency in a sector that has expanded rapidly and, at times, disorderly over recent years. For operators, the consequence is that managing short-term rentals through fragmented and manual processes has become one of the main sources of operational and compliance risk. The direction of travel is clear: Italy’s non-hotel accommodation sector is leaving behind its pioneering phase and moving towards a more structured and professional model. For property managers, agencies and individual hosts, understanding and managing the new regulatory framework is no longer a competitive advantage. It is now a minimum requirement for remaining in the market. Those who equip themselves with the appropriate tools and expertise will be able to transform regulatory complexity into a mark of reliability in the eyes of both property owners and guests.
