New CIN sanctions in Italy: Why hosts are turning to shared housing in 2026

Since the beginning of 2026, the Italian property market has been undergoing a true revolution. For over a decade, major cities like Rome, Milan, Florence, and Bologna have been overwhelmed by the frenzy of tourist rentals. However, facing the urgency of the housing crisis and the need to regulate a sector that had become uncontrollable, the Italian government has decided to act firmly. The entry into force of drastic new regulations is shaking up the habits of property investors.

The strict implementation of the Italy 2026 CIN (Codice Identificativo Nazionale) and the general tightening of the Italy short-term rental law are completely redrawing the accommodation landscape. At Roomlala, we observe a massive and extremely positive shift on a daily basis: fleeing new administrative constraints, costly safety standards, and an overwhelming tax burden, hosts are increasingly turning towards long-term rentals and shared housing in Italy. This strategic turnaround finally offers a real breath of fresh air for student housing in Italy, which was suffering from a dramatic shortage. An analysis of these new rules and the reasons why traditional renting is once again becoming the most profitable and stress-free investment.

Understanding the Italy 2026 CIN and the new sanctions

What is the Codice Identificativo Nazionale (CIN)?

To fully grasp the scale of the change, it is essential to understand what the CIN is. The Codice Identificativo Nazionale is a unique and mandatory code for anyone offering a property for rent for stays of less than 30 days. Although the idea of a national register sprouted a few years ago, it is in 2026 that the system became fully operational and unavoidable. This code is issued by the Ministry of Tourism via the Banca Dati Strutture Ricettive (BDSR).

Concretely, this code must appear absolutely everywhere: on online listings, on the rental contract, and even physically at the entrance of the building or flat. The objective of the Italian state is clear: to eradicate the underground economy, track every tourist overnight stay, and ensure that every host pays their local and national taxes. For hosts accustomed to a certain level of flexibility, this obligation represents additional administrative overhead, requiring complex online procedures and rigorous compliance.

Deterrent fines for offenders

What is truly making the short-term rental market tremble in 2026 are the sanctions associated with non-compliance with the CIN. The Italian legislator has not done things by halves. The absence of registration and possession of the CIN exposes the host to colossal fines ranging from 800 to 8,000 euros. Furthermore, simply possessing the CIN but forgetting to display it clearly on listings or outside the accommodation is punishable by a fine ranging from 500 to 5,000 euros.

Controls have intensified. Local authorities now cross-reference data from booking platforms with tax records. At Roomlala, we always remind our community that legal compliance is paramount. These fines, which can wipe out several months of rental income in an instant, are pushing many hosts to reconsider the viability of their business model based on transient tourism.

New mandatory safety standards

Beyond simple administrative registration, the new regulation imposes drastic safety standards for tourist rentals. In 2026, any flat rented for short-term stays must be equipped with combustible gas and carbon monoxide detectors. Furthermore, the presence of portable fire extinguishers compliant with the law, placed in strategic and easily accessible locations, has become a legal requirement.

These obligations, while legitimate for the safety of travellers, represent a significant installation and maintenance cost for hosts. It is necessary to call on certified professionals for installation and to schedule periodic checks. These additional fixed costs eat into the profitability of short-term rentals, making the model much less attractive than it was five years ago.

Host taxation Italy 2026: The end of the tourist Eldorado?

Lowering the professionalisation threshold: The threat of the Partita IVA

One of the major changes in host taxation in Italy in 2026 concerns the threshold from which a rental activity is considered professional. Previously, a host could rent up to four flats for short-term stays while maintaining their status as an individual. In 2026, this threshold was drastically lowered: from the third property rented on a short-term basis, the activity is automatically reclassified as a commercial activity (attività d'impresa).

This reclassification is a real earthquake. It forces the host to open a "Partita IVA" (the Italian VAT number), to register in the Chamber of Commerce's business register, and above all, to contribute to the Italian social security (INPS). The costs associated with accounting management (fees for an accountant) and mandatory minimum social contributions literally destroy the profitability of small investors who owned three or four small studios dedicated to tourism.

The tightening of the "cedolare secca"

Even for hosts who remain below the three-property threshold, taxation has become heavier. The very advantageous flat-rate tax regime, known as the "cedolare secca", has been revised upwards for short-term rentals. While it is maintained at 21% for the first property rented out, the tax rate automatically climbs to 26% for the second property.

This 5-percentage-point increase on gross income represents a significant shortfall at the end of the year. When you add to this the tourist tax to be collected and paid over, cleaning fees, tourist platform commissions, and the new safety expenses, the net yield of short-term rentals melts like snow in the sun. It is a mathematical fact: the risk and effort are no longer rewarded at their fair value.

The impact on the rental of individual rooms

A point of crucial vigilance concerns the very definition of "real estate property" by the Italian tax authorities. Many hosts thought they could bypass the rules by renting out one large flat, but dividing it to rent out three separate individual rooms for short-term stays. Beware, according to recent tax interpretations, the simultaneous and independent rental of several rooms with separate short-term contracts can, in some cases, accelerate the reclassification into a professional activity.

This is where the legal boundary is essential. Renting rooms by the night is akin to an "affittacamere" activity (professional guest rooms), subject to strict rules. Conversely, renting these same rooms to students for an entire university year falls under the standard residential rental regime, which is totally exempt from these new tourist constraints.

Why shared housing in Italy is becoming the number one alternative

A fundamental legal distinction that protects hosts

Faced with this repressive and fiscal arsenal, the solution for Italian hosts is clear: a return to long-term renting. It is vital to legally distinguish between tourist rentals (less than 30 days, subject to the CIN and hotel standards) and residential or student rentals. Classic Italian contracts, such as the "4+4" (open), the "3+2" (rent-controlled), or the transitional contract for students (from 6 to 36 months), completely escape the CIN regulation.

By opting for these medium or long-term leases, the host does not need to register with the Ministry of Tourism's database, does not have to install mandatory fire extinguishers (although basic safety remains essential), and does not risk any reclassification as a business, regardless of the number of properties they own. It is a return to administrative simplicity.

Stable profitability and an end to daily hassles

Shared housing in Italy currently offers the best yield/tranquillity ratio. While the rent per night may seem higher on paper, the economic reality is quite different once expenses are deducted. Shared housing allows one to rent a large flat by individual rooms to students or young professionals. The overall rent collected is often higher than that of a classic rental to a single family, while guaranteeing a 100% occupancy rate throughout the year.

Furthermore, the practical advantages are immense:

• No more constant turnover: No need to manage key handovers at 10 pm, flight delays, or lost travellers.
• Zero daily cleaning costs: Tenants look after their own living space themselves.
• Absence of seasonality: Income comes in every month, even in November or February, periods that are often slow for tourism.
• Reduced wear and tear on furniture: Unlike holidaymakers, long-term tenants take care of their home.

Case study: Giulia's successful transition in Florence

Let's take the concrete example of Giulia, the owner of a large 120 m² flat in the centre of Florence. Until 2025, she rented this property for short-term stays. With the arrival of the mandatory CIN, the prospect of having to pay 26% tax (because she owns another small studio), and the obligation to install costly safety equipment, she decided to change her strategy in 2026.

Giulia refurbished her flat to create four beautiful student rooms. She signed 12-month rental contracts. The result? She no longer has to worry about the CIN. She benefits from lighter taxation thanks to the student contract with capped rent (which allows, in certain municipalities, the cedolare secca to fall to 10%). Her annual net income increased by 15% compared to the previous year, and she has regained a real quality of life, freed from the stress of last-minute bookings.

Responding to a major societal crisis

This shift of hosts towards long-term renting is excellent news for Italian society. Student housing in Italy was going through an unprecedented crisis. In Milan, Bologna, or Rome, students sometimes had to camp in tents in front of universities to protest against exorbitant rents and the lack of supply, as housing was being cannibalised by tourism.

The year 2026 marks a turning point. The massive return of flats to the traditional rental market is helping to ease supply. Students and young workers are finally finding rooms in shared housing at decent prices. This market rebalancing is healthy and sustainable because it is based on a strong structural need and not on the fluctuations of international tourism.

The tax benefits of student contracts

To encourage this movement, the Italian state has maintained very attractive tax schemes for hosts who accommodate students. The "contratto per studenti universitari" (contract for university students), lasting from 6 to 36 months, is the perfect tool. When coupled with a territorial agreement (canone concordato), it allows the host to benefit from a reduction in property tax (IMU) and a tax rate on rental income reduced to just 10%, compared to the 21% or 26% for tourist rentals.

This is an irrefutable financial argument. Why risk fines of 8,000 euros and pay 26% tax on short-term rentals, when you can rent legally to students, with guaranteed demand and tax reduced to 10%? The calculation is quickly made for most savvy investors.
