The rules governing short-term rentals in Italy have been recalibrated by the recent budget changes and the updated guidance from the Agenzia delle Entrate. This article walks through the essential points every private host, property manager and platform should know, focusing
on the new two-unit threshold, the mechanics of the flat-rate tax known as cedolare secca, and the practical duties imposed on intermediaries. For clarity, short-term rental refers to agreements for residential properties that last no more than 30 days, often including ancillary services such as cleaning or linens when not crossing into full hospitality operations.
Because the legislation distinguishes occasional private letting from organized commercial activity,
hosts must assess how many apartments they operate. The law and official guidance establish bright-line rules that affect taxation, reporting and administrative obligations. The legal framework includes the budget law (art. 1 comma 17, L. 30 dicembre 2026, n. 199) and subsequent updates to the tax authority’s guide published in April 2026. Understanding these changes early helps avoid surprises such as forced reclassification as an enterprise or application of different tax
rates and compliance duties.
Main fiscal change: the two-unit threshold and presumption of business
The cornerstone of the reform is the two-unit threshold. As of 1 January 2026, taxpayers who allocate more than two apartments to short-term letting in a tax year are presumed to be carrying on an entrepreneurial activity. This legal presumption shifts the burden: three or more units typically trigger obligations typical of a business, including bookkeeping duties and the likely need to register for a partita IVA. The rule aims to better separate casual hosts from scale operators and to align fiscal treatment with the degree of organization and economic scale of the activity.
For many small hosts who operate one or two apartments, the classification remains as a private activity and the simplified rules continue to apply. However, exceeding the threshold is not a trivial counting exercise: it changes tax categories, exposes the operator to potential local regulatory controls, and may require compliance with regional or municipal authorizations that apply to commercial accommodation providers. Host planning should therefore include both tax and local regulatory checks.
Tax mechanics: cedolare secca rates and taxable base
Rates and progressive structure
The cedolare secca remains a central option for taxable income from short lets, but the 2026 framework introduces differentiated treatment by unit count. The regime allows a 21% rate for income from a single unit selected by the taxpayer and a 26% rate for the second unit; draft texts and commentary also indicate higher marginal rates (for example 30%) may apply to third and fourth units, signaling a steeper progression for those beyond the two-unit limit. Choosing to apply the flat-rate tax means replacing standard income taxation (IRPEF and add-ons) and those related registration and stamp duties for amounts covered by the option.
How the base is calculated
The taxable base is the full contract gross rent, including fees for included services such as cleaning or linen when these are charged as part of the price rather than separately billed. The gross corrispettivo is therefore central to tax calculation. Note that electing the cedolare secca removes the right to increase the rent, including any ISTAT-linked updates, for the duration of the option. Owners should model net returns under both ordinary taxation and the flat-rate route before deciding.
Intermediaries and platforms: reporting, withholding and exceptions
Digital platforms and agencies play a formal role as reporting nodes. Updated guidance from the Agenzia delle Entrate (April 2026) requires intermediaries who mediate contracts or handle payments to transmit contract data including address, duration, CIN (Codice Identificativo Nazionale) and gross consideration. Transmission deadlines remain strict: reports are due by 30 June of the year following the contract, with correction rules where needed. The goal is a unified database that lets the tax authority monitor volumes and compliance across the short-term rental market.
When intermediaries collect or disburse rents, they act as tax substitutes and must apply a 21% withholding on the gross amounts as an advance payment, remitting it via F24 with the specific code 1919. The guidance clarifies exceptions: no withholding applies if payment is made by check directly to the owner or when the intermediary provides only payment processing services without contractual intermediation. Non-EU platforms face parallel obligations for communication and data retention, as set out in the updated manual.
Sanctions, practical advice and next steps
Failure to comply with reporting or withholding rules exposes intermediaries and hosts to administrative penalties: omissions or inaccurate communications fall under Article 11, paragraph 1 of D.Lgs. 471/1997, while incorrect withholding handling may trigger sanctions under Article 14 of the same decree. Hosts who manage one or two units will often find the cedolare secca simplest, but those approaching or exceeding the threshold should reassess the activity’s legal form, check local authorizations and consult a tax professional to evaluate conversion to an enterprise and the opening of a partita IVA.
In practice, review your portfolio now: count apartments per tax year, map how rents and services are invoiced, and confirm platform reporting workflows. Early alignment with the new rules reduces risk and lets compliant operators use transparency as a market advantage.
