A foreign owner can still let an Italian home short-term in 2026, but the rules have tightened and the maths is more demanding than the headline yields suggest. Every short let now needs a national identification code, the CIN, displayed on the building and quoted in every listing. Rental income is taxed under the cedolare secca flat regime at 21% on one property you designate and 26% on the others, and from 2026 letting more than two units tips the activity into a taxed business. Rome remains one of Italy’s strongest short-let markets, with gross yields running from roughly 6% to 12% depending on the district, but high purchase prices compress the net return. This guide sets out what you must do, what you will pay, and what you can realistically expect to earn.
Short-term letting in Italy in 2026, at a glance
- A national code (CIN) is mandatory: it must appear on the building and in every advertisement, with fines from 800 to 8,000 euros for letting without one.
- Income is taxed under the cedolare secca at 21% on one designated property and 26% from the second property let in the same year.
- From 1 January 2026, letting more than two apartments short-term is presumed to be a business, with VAT registration and social contributions.
- In Rome, the tourist tax on a short let is 5 to 6 euros per guest per night, for up to ten nights.
- Rome runs an average nightly rate of roughly 140 to 200 euros and annual occupancy between about 64% and 77%, among the highest in Italy.
The rules you must follow
The starting point is the CIN, the Codice Identificativo Nazionale, a national identification code introduced by Law 191/2023. Since the end of 2024 it has been mandatory for every property offered for short-term or tourist rental: you obtain it through the national database, the BDSR, display it on the outside of the building, and quote it in every listing and advertisement. Booking platforms are required to show it and to remove listings that lack one. The penalties are real, from 800 to 8,000 euros for letting without a CIN, and a parallel obligation requires working gas and carbon-monoxide detectors and a fire extinguisher in each unit.
On top of the national code, Lazio operates its own regional code, the CIR, issued through the regional RADAR platform, and you register the activity with Rome through the municipal one-stop desk, either as a tourist lodging, a lighter declaration, or as a casa vacanze, a fuller one. A short lease here means a locazione breve, a rental of no more than thirty days, which does not need to be registered as a formal lease contract. One Rome-specific limit is already in force: inside the UNESCO-protected historic centre you can no longer convert a non-residential property, an old office or shop, into a holiday rental.
How Are Short Lets Taxed?
The cedolare secca is a flat substitute tax on rental income that replaces income tax and registration tax on the rent. For short lets it runs at 21% on a single property you designate each year in your tax return, and at 26% on any further properties let short-term in the same year. The choice of which property gets the 21% rate is yours, made in the return, and you would normally assign it to the unit earning the most. Where a platform such as Airbnb handles the payment, it withholds 21% at source as an advance, and you settle any balance when you file. For a non-resident owner this is usually simpler and lighter than ordinary taxation, which is part of the appeal.
When Does Letting Become a Business?
There is a line beyond which short letting is treated as a business rather than the management of private property, and 2026 moves that line. Through 2025 the threshold was more than four apartments let short-term in a year. From 1 January 2026 it falls to more than two: let three or more units short-term and the law presumes a business, which means a VAT number, registration with the business register, and social-security contributions, and the cedolare secca is no longer available. For an owner with a single prime apartment this changes nothing. For anyone thinking of building a small portfolio of lets, it is the single most important number to plan around.
What Does It Actually Yield?
Rome is a genuinely strong market on the top line. Average nightly rates run from about 140 to 200 euros depending on the season and the address, occupancy sits between roughly 64% and 77% across the year, and gross yields by district run from around 6% in Prati to 8% or more in the historic centre. Modelled net returns of around 7% to 8% on a well-run central apartment compare favourably with the 4% or so a traditional long lease produces. The caveat is entry price. The analytics firm AirDNA scores Rome at the very top for rental demand but low for investability, precisely because central purchase prices are high enough to compress the yield on otherwise strong revenue. A short let in Rome earns well; whether it earns well relative to what you paid depends entirely on the price of the asset.
Short-let or long lease: the trade-off
| On a central Rome apartment | Short-let | Long lease |
|---|---|---|
| Tax on rental income | cedolare secca 21%, 26% from the second unit let | cedolare secca 21% |
| Gross yield | about 6% to 12% by district | lower, but steadier |
| Modelled net yield | about 7% to 8% | about 4% |
| Admin and compliance | CIN, regional code, tourist tax, guest turnover | one tenant, minimal |
| Occupancy | seasonal, about 64% to 77% | full year |
What Does It Mean for a Foreign Owner?
For an overseas owner of a Roman apartment, short letting in 2026 can work well, but it is no longer a casual arrangement. It rewards a compliant set-up: a national and a regional code, the right municipal registration, the safety equipment, clean cedolare reporting, and either your own time or a professional manager to handle guests, the tourist tax and the platforms. The decision is less about whether the market is strong, it is, than about whether your specific apartment, at the price you hold it, and your appetite for the administration, make the net return worth it against a straightforward long lease. That is a calculation worth doing properly before you list.
You can see the kind of Rome home this applies to in an apartment for rent in the centre of Rome and in a guesthouse in the historic centre, both suited to exactly this kind of letting. We covered the same ground, with different numbers, in our earlier pieces on how much you can really earn from a short-term rental in Rome and on apartments in Rome as a short-let investment, and on what it costs to buy the asset in the first place in our guide to what a foreign buyer really pays in Italy.
