The landscape of fiscal incentives linked to property renovations has been clarified in recent years, and a targeted relief remains available for buyers of units that belong to buildings entirely renovated. In practical terms, the measure applies when developers or housing cooperatives complete comprehensive works and then sell
or assign the units within the required timeframe. Buyers who meet the conditions can access an Irpef deduction, but their entitlement depends on a set of formal requirements, precise documentation and specific payment methods. Understanding the rules in advance avoids losing the benefit at closing.
Who qualifies and what types of property are covered
Eligibility is limited to units that are part of an entirely renovated building where interventions consisted of restoration,
conservative rehabilitation or building renovation carried out by construction firms or housing cooperatives. The works must be finished and the producer must sell or assign the units within eighteen months of completion. The relief is available both for an primary residence and for other types of housing; it also extends to associated parking spaces and garages when the required pertinenziality (link to the housing unit) exists. For acquisitions made in 2026 the regime
provides a 50% deduction where the unit becomes the buyer’s main home and 36% for other uses, with a ceiling of 96,000 euro of eligible expenditure.
How the deduction is calculated
The calculation departs from actual invoice totals: instead of documenting renovation costs, the law accepts a forfait base equal to 25% of the sale price recorded in the deed of purchase or assignment. In practice, the tax benefit is computed on this forfait amount, not on detailed construction invoices, and the resulting deduction is split into ten equal annual instalments. It is therefore essential that the deed explicitly states the date when the works were completed and confirms that the unit belongs to a fully renovated building; absent this wording the buyer should obtain a formal declaration from the developer affirming the required conditions.
Garage and parking space rules
The incentive covers the construction or purchase of garages and parking places when they are tied to the dwelling by the necessary pertinenziality. The key constraint is that the garage must be of new construction realized as part of the redevelopment, not a mere change of use achieved through routine renovation. The same 50% and 36% rates apply in 2026 for garages linked to a primary or secondary house respectively, and the cap on eligible spend remains aligned with the general limit. The deed must record the pertinenziality, and the builder should supply a breakdown of costs attributable solely to the garage’s construction.
Payment methods and documentary precautions
Standard practice requires payment by bank or postal transfer (a bonifico) so that traceability supports the claim. However, if payment was not made by bonifico the benefit is not automatically lost: under administrative guidance (see circular n. 43/E of the tax authority) the buyer may rely on a notarized deed plus a substitute affidavit from the seller stating that proceeds were correctly recorded in the company accounting. This alternative is workable but demands meticulous verification of the seller’s accounting records and careful drafting of declarations.
Practical tips and legal framework
The rules rest on article 16-bis of DPR 917/1986, which defines deductible works and the administrative mechanics for recovering part of renovation-related costs. Historically the standard deduction was 36% with a lower cap per unit, but temporary enhancements and later measures have raised limits for certain periods; for the purchases governed by the current provision the operative ceiling to check is 96,000 euro. Other practical points: if the unit is partly used for professional activity the deductible share can be adjusted; a remaining deduction may be transferred to a buyer on resale if agreed; in case of death the right can pass to an heir who maintains physical possession. Before signing, buyers should ask a notary or tax professional to review the deed and to obtain any additional declarations from the builder to document completion date, building-wide intervention and cost breakdowns.
In short, the opportunity to obtain significant tax savings when buying units within completely renovated buildings and related garages is real, but it hinges on formal evidence: the completion date, the builder’s identity and declarations, the pertinenziality of parking areas, and the payment trace. Securing the right paperwork at the time of purchase and seeking professional guidance will protect the buyer’s claim to the Irpef deduction and prevent last-minute surprises.
