In accordance with the policy objectives of tax cut and fee reduction and the reform of taxation legislation，China’s tax policy adjustment in 2018 is relatively large. Among them，the main types of taxes including value-added tax，personal income tax and corporate income tax have implemented policy adjustments such as lowering the tax rate，preferential tax rate structure and increasing deductions. Stamps tax，property taxes，urban land use taxes and other taxes have also introduced relevant tax cut policies. The policies of environmental protection taxes，tobacco leaf tax，ship tonnage tax，farmland occupation tax and vehicle purchase tax have been improved in the legislation. From the perspective of taxation operation，the tax revenue growth in 2018 is characterized by high in the first half and low in the second half. The tax structure still maintains the status of domestic value-added tax，corporate income tax，personal income tax and domestic consumption tax as the main body.
