According to the Notice on Strengthening the Management of Tax Reduction and Exemption (Cai Shui [2008] No. 48), enterprises that install solar photovoltaic power generation equipment that meet the requirements are eligible for a 10% income tax deduction. From the Tax Preferential Catalogue, you may not be able to find the said preferential policies, but it is still in compliance with relevant policies. In addition, under the same Notice, enterprises that install non-renewable energy industry special equipment such as solar photovoltaic power generation equipment and those that purchase special solar photovoltaic industry equipment are eligible for a double tax deduction. Therefore, if an enterprise is in need of such a preferential policy, it can apply for the double tax deduction specified in the Notice. In addition, in order to better promote the development of new energy, the state has launched a series of energy-saving and emission reduction policies, such as providing subsidies for renewable energy projects, and reducing or exempting corporate income taxes, land use taxes and other taxes. Enterprises can refer to these policies when doing business.
