Policy basis: Article 91 II of the Regulations for the Implementation of the Enterprise Income Tax Law of People's Republic of China (PRC). Characteristics of enterprise income tax 1. The tax basis is taxable income. The tax basis of enterprise income tax is the net income of taxpayers after deducting costs, expenses, taxes, losses and other expenses, which is not equal to the accounting profit realized by enterprises. 2. The calculation of taxable income is very complicated. Enterprise income tax is based on net income. Therefore, the calculation of taxable income needs to involve the collection and distribution of costs and expenses in a certain period of time. Because the government often regards income tax as an important tool to adjust national income distribution and implement economic and social policies, in order to treat taxpayers' different income items differently, it is necessary to exclude some income from taxable income by not counting items. Due to the above two reasons, the calculation procedure of taxable income is more complicated. 3. Taxation is based on the principle of affordability. Enterprise income tax is based on the taxpayer's production, business income and other income, and the principle of affordability is implemented, that is, more income, greater affordability, and more taxes; Low income, poor affordability and low tax revenue; No income, no affordability, no taxes. This method of linking the income tax burden with the taxpayer's income is convenient to embody the basic principle of tax fairness. 4, the implementation of the annual collection and management law, which comprehensively reflects the business performance of enterprises through profit income, usually calculated and measured on an annual basis. Therefore, enterprise income tax is based on the taxable income of the whole year, paid in advance monthly or quarterly, and settled at the end of the year, which is consistent with the accounting year and accounting period, which is conducive to the consistency of tax collection and management and enterprise accounting period. Third, the role of enterprise income tax Enterprise income tax plays an important role in organizing fiscal revenue, promoting social and economic development, and implementing macro-control. Enterprise income tax regulates the profit distribution relationship between the state and enterprises, which is the most important aspect of China's economic distribution system and the premise and basis for dealing with other distribution relationships. The role of enterprise income tax is mainly reflected in two aspects: 1 and the role of fiscal revenue. Enterprise income tax is the second largest main tax in China and plays a very important role in organizing national tax revenue. 2. Macro-control function. Enterprise income tax is the most important tax for the state to implement preferential tax policies. There are many preferential tax measures, such as tax reduction and exemption, tax rate reduction, additional deduction, accelerated depreciation, investment credit, income reduction and so on. It is the main policy tool to implement national industrial and social policies and macro-control. As an important means of national macro-control, enterprise income tax not only organizes fiscal revenue for the country, but also promotes China's industrial restructuring and sound and rapid economic development.
