As of 20 August 2026 the Italian Revenue Agency (Agenzia delle Entrate) maintains the Ecobonus incentive established by Law No. 296/2006 a cornerstone of the fiscal strategy to promote energy efficiency retrofitting of existing residential and commercial buildings. This measure permits taxpayers who incurred qualifying expenses during the preceding tax year to claim deductions through the annual tax return specifically referencing lines E61 and E62 of the Model 730/2026 or Section IV of the Modello Redditi PF. The regulation mandates the disclosure of detailed expense outlays and standardized identification codes for each intervention ensuring compliance with EU state aid regulations and domestic environmental fiscal policy. The Ecobonus forms an integral component of the European Unions Renovation Wave and Fit-for-55 packages aiming to reduce building-related carbon emissions by 55 percent by 2030. Proper documentation including original invoices contractor declarations and energy performance certificates must be retained by taxpayers for a minimum of five years to substantiate claims during potential audits conducted by the Financial Police (Guardia di Finanza) or the Revenue Agency verification units.
Key Takeaways
- Expanded Declaration Channels: Taxpayers may now utilize both the simplified Model 730 pathway via lines E61-E62 and the full Model Redditi PF Section IV to report Ecobonus-related expenditures increasing flexibility for diverse fiscal profiles and encouraging broader participation in the incentive scheme.
- Mandatory Documentation Retention: A strict five-year retention requirement applies to all supporting records including invoices technical certifications and intervention codes necessitating robust internal archiving systems for individuals and businesses alike to mitigate risks during tax assessments.
