Italy and other EU member states also offer tax incentives for installing photovoltaic systems. In May 2020, Italy introduced the “110% superbonus” tax deduction for energy efficiency and seismic renovation of residential buildings, offering a tax exemption amounting to 110% of the renovation costs. There are three available tax exemption methods: (i) an income tax credit; (ii) suppliers covering the entire cost and receiving a tax exemption; and (iii) transferring the tax exemption amount to offset loans from banks or insurance companies.[50] Under this policy, the installation of residential photovoltaic systems can receive a tax credit of up to EUR 48,000.[51] Starting in 2024, Italy’s super subsidy policy will lower the tax-exempt rate to 70%.[52]
