The term Superbonus refers to the strengthening of existing tax deductions for Ecobonus energy upgrades, Sismabonus seismic interventions and Bonus Edilizia for the installation of photovoltaic systems.
Specifically, this strengthening occurs due to the raising to 110% of the tax deduction already in force, on the meeting of certain criteria and solely for expenses incurred between 1 July 2020 and 31 December 2021 (for AICP associations and other bodies with the same purpose, and solely for the Ecobonus, the 110% deduction is applicable until 30 June 2022).
