The decision to buy a house goes far beyond choosing the right layout: it requires a clear understanding of the tax framework that surrounds property transactions. In practice, taxes at purchase, possible reductions for a primary residence, the consequences of choosing between VAT or a registration tax regime, and the recurring
levies on a second home all affect the final budget. This introduction frames the fiscal elements you will face and why each one matters when planning the purchase or ownership of a property.
Knowing which levies apply, how they are calculated and what formal steps unlock incentives can save significant money. This article examines the main duties at acquisition, explains the price-value regime and walks
through the requirements for the first home incentive. It also describes the ongoing charges for a secondary dwelling, and the practical renting options—such as agreed rents and the cedolare secca—that can reduce tax exposure.
Taxes at purchase and the price-value option
When you sign the deed, the tax treatment depends largely on the seller’s status and on whether the sale is subject to VAT or to the registration
tax. If the seller is a private person or a company that sells without VAT, the registration tax is typically applied on a proportional basis (ordinary rate 9%), while the mortgage and cadastral taxes are often fixed amounts. If the sale is subject to VAT, reduced rates may be available (for example 4% for a qualifying first home or 10% in many other cases). Understanding which levy applies avoids unpleasant surprises at closing.
The price-value regime is a practical tool that often lowers the tax base: by opting for this regime in the deed, the fiscal value is aligned with the property’s cadastral value rather than the market price. If the declared price does not exceed the cadastral benchmark, the tax authorities cannot challenge that declared amount for tax purposes. To use this option you must explicitly declare it in the deed and meet specific requirements, such as buying the dwelling for residential use and not triggering exclusions linked to sales by VAT-registered developers.
First home: eligibility, obligations and deadlines
Buying with the first home benefit can substantially reduce upfront levies, but it demands precise conditions and timely declarations. Typical rules include not owning another property in the same municipality (unless you commit to sell within stated deadlines), transferring your official residence to the new home within a set period (commonly 18 months), and ensuring the property is not classified among luxury categories. These conditions must be declared at the time of the final deed, because the advantage applies only to the completed transfer and not to preliminary agreements.
Timing is particularly important: rules about how long you have to sell an existing home vary with circumstances. If the previously owned house was purchased without special benefits, it generally must be sold before acquiring the new property; if it was bought using a first-home benefit, you may have additional time to dispose of it. Be aware that from 2026 the allowable period in some cases extends to two years. Missing these deadlines typically results in loss of the benefit and an obligation to pay the unpaid taxes plus interest and penalties.
Second home: recurring costs and renting strategies
Owning a second property generates ongoing fiscal duties that need planning. The main recurring charges are IMU (a municipal property tax calculated on the revalued cadastral income multiplied by statutory coefficients and municipal rates), TARI (a waste service charge payable regardless of actual use), and taxation under IRPEF rules depending on whether the property is left vacant or is rented out. If the property is not rented, tax rules often apply a notional income; if it is leased, the rent either contributes to your total taxable income or can be subjected to alternative tax regimes.
Tax treatment of rental income
Rental receipts can be handled in different ways. Without opting for any special regime, the gross rent usually forms part of your overall taxable income under IRPEF. Alternatively, landlords can choose specific regimes that simplify taxation and sometimes lower the effective rate. Selecting the right option depends on your overall tax profile, expected rental income and whether you prefer predictable flat taxation to variable progressive taxation.
Benefits of agreed rent and the cedolare secca
Leases agreed under local frameworks (canone concordato) offer practical fiscal advantages: municipalities often apply reduced IMU rates or other concessions, and you may be eligible for a favorable cedolare secca rate (commonly 10% for agreed rents) versus higher rates on open-market contracts (for example 21% under the ordinary flat-rate option). If the landlord does not opt for the cedolare secca, the agreed-rent regime usually allows larger deductions on the rental income when calculating IRPEF, lowering the taxable base. Comparing these alternatives helps optimize net returns and overall tax exposure for a second dwelling.
In short, tax choices at purchase and during ownership materially influence the cash needed and the long-term cost of a property. Taking time to identify whether VAT or registration tax applies, evaluating the price-value regime, respecting the rules for first home benefits and choosing an appropriate rental strategy can produce substantial savings and reduce future surprises.
