Italy rental regulations: tax and registration rules

In Italy, the legal and fiscal landscape for rental properties is characterized by strict registration requirements and complex taxation rules for short-term stays. According to rulings from the Corte di Cassazione, a rental contract that is not registered within the legal timeframe is considered null. However, late registration can retroactively validate the agreement and rectify this nullity, provided the necessary taxes are paid.

For the growing short-term rental market, such as those managed via Airbnb, tax obligations depend on the chosen regime. Owners can opt for the ordinary IRPEF progressive rate or a flat-rate regime (for revenues under €65,000) with rates of 15% or 5% for the first three years. Additionally, the role of a co-host does not automatically transfer tax liability; the income remains attributable to the property owner unless the co-host operates under a specific legal title like sub-leasing.

Local regulations also add layers of complexity, with cities like Rome and Milan imposing specific limits on rental days and registration requirements to manage urban housing.
