Application Of Data Mining Technology In Taxation

With the rapid development of computer technology,the combination of computer technology and traditional tax management has become a major direction for the current taxation department to carry out informational transformation of taxation work.Through the data mining technology,these idle data can be analyzed and extracted,and the potential knowledge and laws can be acquired.Tax audits are the most important and cumbersome matters,requiring tax officers to develop tax audit plans based on their tax history and business data.Therefore,the paper uses data mining technology to analyze the historical data and business data of the enterprises to realize the information operation of the tax base selection,and use the decision tree classification algorithm to determine whether the enterprise has tax evasion.First of all,the background and significance of data mining technology in taxation work are expounded.On this basis,the present research situation of data mining technology is analyzed.Secondly,the application of data mining technology in taxation is analyzed.And the characteristics of the tax processing data,the tax treatment and the steps of the tax audit case selection,the data collection,the classification of taxation data,are analyzed the key technology data mining and the decision classification algorithm of the taxation work in detail,carries on the demand investigation to the transaction processing business.Finally,The data mining module is realized by using the data of enterprise tax and tax audit data,which includes data preparation,attribute selection,decision tree generation,data representation and decision analysis.Through the use of the system,the taxation data of key industries,abnormal declaration enterprises and key tax source households are selected,and the tax audit cases are selected through the decision classification algorithm in the data mining module,and the key tax inspection objects are selected.It helps taxpayers to avoid duplication of cases,greatly improving the efficiency of tax regulation and effectiveness.
