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

Since the beginning of 2026, the Italian real estate market has been undergoing a true revolution. For more than a decade, major cities like Rome, Milan, Florence, or Bologna have been overwhelmed by the frenzy of tourist rentals. However, faced with 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 real estate investors.

The strict implementation of the CIN Italy 2026 (National Identification Code) and the general tightening of the short-term rental law in Italy 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 a tax system that has become overwhelming, hosts are increasingly turning toward 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. Here is a breakdown of these new rules and the reasons why traditional renting is once again becoming the most profitable and peaceful investment.

Understanding the CIN Italy 2026 and new penalties

What is the National Identification Code (CIN)?

To fully grasp the scale of the change, it is essential to understand what the CIN is. The National Identification Code is a unique and mandatory code for anyone offering a property for rent for periods of less than 30 days. Although the idea of a national registry sprouted a few years ago, it was 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).

In concrete terms, this code must appear absolutely everywhere: on online listings, on the rental agreement, and even physically at the entrance of the building or apartment. The goal 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 flexibility, this obligation represents additional administrative burdens, requiring complex online procedures and rigorous compliance.

Deterrent fines for offenders

What is truly shaking up the short-term rental market in 2026 are the penalties associated with non-compliance with the CIN. The Italian legislator has not taken half measures. The lack of registration and possession of the CIN exposes the host to colossal fines ranging from 800 to 8,000 euros. Furthermore, the mere fact of 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 apartment rented on a short-term basis 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 guests, represent a significant installation and maintenance cost for hosts. It is necessary to call on certified professionals for installation and schedule periodic checks. These additional fixed costs nibble away at the profitability of short-term rentals, making the model much less attractive than it was five years ago.

Host taxation in Italy 2026: The end of the tourist El Dorado?

Lowering the professionalization threshold: The threat of the Partita IVA

One of the major changes in host taxation in Italy 2026 concerns the threshold from which a rental activity is considered professional. Previously, a host could rent up to four apartments on a short-term basis 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 true earthquake. It forces the host to open a "Partita IVA" (the Italian VAT number), to register in the Chamber of Commerce business register, and above all, to contribute to the Italian social security (INPS). The costs associated with accounting management (fees for a certified 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 under the three-property threshold, the tax burden has increased. The very advantageous flat-rate tax regime, known as the "cedolare secca," has been revised upward for short-term rentals. While it is maintained at 21% for the first rented property, 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 new safety expenses, the net yield of short-term rental melts like snow in the sun. It is a mathematical fact: risk and effort are no longer rewarded at their true value.

The impact on the rental of individual rooms

A crucial point of 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 a single large apartment, but by dividing it to rent three distinct individual rooms on a short-term basis. Be careful, 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 as a professional activity.

This is where the legal boundary is essential. Renting rooms by the night is akin to an "affittacamere" type activity (professional guest rooms), subject to strict rules. Conversely, renting these same rooms to students for an entire academic year falls under the classic residential rental regime, 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 rentals. It is vital to legally distinguish tourist rentals (less than 30 days, subject to the CIN and hotel standards) from residential or student rentals. Classic Italian contracts, such as the "4+4" (free market), the "3+2" (regulated rent), 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 on the Ministry of Tourism's database, does not have to install mandatory fire extinguishers (although basic safety remains a must), and risks no reclassification as a business, regardless of the number of properties they own. It is a return to administrative simplicity.

Stable profitability and the end of daily hassles

Shared housing in Italy now offers the best yield/tranquility ratio. While the nightly rent may seem higher on paper, the economic reality is quite different once expenses are deducted. Shared housing allows for renting a large apartment 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 guests.
• Zero daily cleaning fees: Tenants maintain their own living space.
• Absence of seasonality: Income comes in every month, even in November or February, which are often slow periods for tourism.
• Reduced wear and tear on furniture: Unlike vacationers, long-term tenants take care of their home.

Use case: Giulia's successful transition in Florence

Let's take the concrete example of Giulia, the owner of a large 120 m² apartment in the center of Florence. Until 2025, she rented this property on a short-term basis. 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 remodeled her apartment to create four beautiful student rooms. She signed 12-month rental agreements. The result? She no longer has to worry about the CIN. She benefits from reduced taxation thanks to the regulated student rental contract (which allows, in some municipalities, for the cedolare secca to drop to 10%). Her annual net income increased by 15% compared to the previous year, and she regained a true quality of life, freed from the stress of last-minute bookings.

Student housing in Italy: A boon for young people and security with Roomlala

Responding to a major societal crisis

This shift of hosts toward long-term rentals 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 homes were being cannibalized by tourism.

The year 2026 marks a turning point. The massive return of apartments to the classic 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 relies 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 incentives for hosts who house students. The "contratto per studenti universitari" (contract for university students), with a duration of 6 to 36 months, is the perfect tool. When it is 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 only 10%, compared to the 21% or 26% for tourist rentals.

This is an irrefutable financial argument. Why risk 8,000-euro fines and pay 26% taxes on short-term rentals when you can rent legally to students, with guaranteed demand and taxes reduced to 10%? The math is quickly done for the majority of savvy investors.
