Abstract: Tax risk management is the core for building a scientific and rigorous tax collection and management system. In order to achieve better tax risk management, improve the scientific and applicability of tax risks and perfect the foundation of tax risk management, a tax risk management platform supporting risk ranking, risk query and risk indicator management that combines tax database and tax risk management is proposed. It can solve the problem that tax departments can not handle a large amount of data in the existing tax risk analysis platform, and is conducive to tax departments to find out various types of risks. It is conducive to the taxation authorities to identify various types of risks that may arise in the taxation process from a large amount of data, so that such risks can be avoided or reduced according to the risk tips.
