In this in-depth article we will clarify everything there is to know about Ecobonus 2025. The guide we provide below is applicable to individuals and businesses and, among other aspects, defines the conditions for applying for the benefits.
Learn all the updates provided by the 2025 Budget Law for building bonuses.
Italian Ecobonus 2025: what it is
The Italian Ecobonus benefit consists of the recognition of tax deductions to the extent of 50% of expenses incurred for the reduction of energy demand and thermal improvement of the building on units used as main residences. These expenses are to be divided into annual installments of equal amount, within a maximum limit of deduction for interventions for the recovery of the building heritage (Article 16-bis of Presidential Decree 917/86 TUIR).
The 2025 Budget Law introduces several changes to the regulations of almost all tax benefits provided for building renovation. The regulations reshape the terms of use and the deduction rates, providing more advantageous conditions for real estate units used as primary residences.
These are reductions from Irpef (personal income tax) or Ires (corporate income tax) granted for interventions that increase the level of energy efficiency of buildings.

Who is eligible for Ecobonus 2025?
The relief is for all taxpayers, both residents and nonresidents, who own the property being worked on.
Individuals who are eligible for the relief:
- Holders of a right in rem to the property;
- Condominium owners, for work on common condominium areas;
- Tenants;
- Those who have the property on loan;
- Business income holders, but only with reference to the capital buildings they use in the course of their business activity.
A cohabiting family member or member of a civil union of the property owner is also eligible for the bonus, in addition to a separated spouse who has been assigned the property in the other spouse’s name, and a more uxorio cohabitee for expenses incurred since January 1, 2016.
In these cases, however, it is essential that the invoice be issued in the name of the person commissioning the work, being part of these categories.
What falls under the Italian Ecobonus and spending limits
The 50% deduction covers interventions involving energy upgrading of real estate units on private and common parts, as well as capital properties subject to business activities in which the following expenses (with the deduction limit next to them) are included as examples:
- Interventions on the envelope of existing buildings (deduction limit € 60,000);
- Installation of solar panels for hot water production (deduction limit €60,000);
- Purchase and installation of windows including frames and replacement of winter air conditioning systems (deduction limit €60,000);

- Purchase and installation of solar screens (deduction limit €60,000);
- Energy upgrading of existing buildings (deduction limit €100,000).
As a reminder, like the other building bonuses, supplies of goods and services put in place to carry out energy upgrades to buildings are subject to reduced VAT at 10%.
Energy saving deductions reduced from 50% to 36% from 2025
From 1 January 2025, the Budget Law has provided for a reduction in the deduction from 50% to 36% for interventions carried out on second homes and in any case on units not used as a primary residence.
This reduction also involves the following years with a gradual reduction for 2026 and 2027 to 36% for primary residences and 30% for second homes.
Another change introduced in the Chamber: interventions to replace winter air conditioning systems with fossil fuel-fired single boilers are excluded from any deduction provided for the years 2025, 2026 and 2027
