Application Of Block-chain In Tax Collection And Management Of Individuals In China

At the beginning of 2019,China's new personal income tax law began to be implemented.The policies of special deduction,taxpayer identification number of natural persons,tax credit and so on show that the state wants to strengthen the policy orientation of tax collection and management of natural persons.Since the reform and opening up,with the continuous improvement of people's living standards,the base of high-income groups in China is also rising.There are various tax avoidance methods for such groups.The difficulty of tax collection and management leads to a large loss of national tax revenue.In order to meet the needs of tax reduction and fee reduction of enterprises and the effective implementation of the new personal income tax law,it is urgent to strengthen the tax collection and management of natural persons.In recent years,block chain technology has developed rapidly.Its de-centralization,distributed storage,consensus mechanism,intelligent contract,asymmetric encryption and other technical characteristics provide a new solution for identity authentication and information management.Block chain ensures the transparency and reliability of transaction records and data,and provides the possibility of "Block Chain + Taxation" model.The State Administration of Taxation has also seen these characteristics of block chain technology,and set up a research team on block chain in June 2017.In the future,block chain technology is likely to play a significant role in reducing the cost of tax collection and management and improving the efficiency of tax collection and management.It will also play a significant role in achieving tax equity and promoting social harmony.Under this background,the study of block chain and natural person tax collection and management conforms to both policy orientation and the development of the times.Based on the existing literature and data,this paper is mainly divided into five parts.The first part combs the theory of natural person tax collection and management,and the working mechanism and technical characteristics of block chain technology,which lays the foundation for the later research.The second part analyses the current situation and problems of tax collection and management of natural persons,and the joint point of block chain technology and tax collection and management.Especially after the promulgation and implementation of the new personal income tax law,the change of tax collection and management mode of natural persons and the possible policy effects are analyzed,and the necessity and feasibility of block chain technology in tax collection and management of natural persons are explored.The third part draws lessons from the experience of some countries in tax collection and management of natural persons,and using block chain technology for information management,hoping to get some inspiration for the design of this model.In the fourth part,based on the previous analysis,a model of natural person tax collection and management system based on block chain technology is designed to solve the problem of information asymmetry in natural person tax collection and management.The fifth part puts forward the main challenges and suggestions of the natural person tax collection and management system model based on block chain technology in the application process.This paper takes the technical means of Taxation Collection and management of natural persons urgently needed to be strengthened as the core.I use literature analysis,theory combined with practice,qualitative and quantitative analysis,experience,model design and other methods.This paper studies the possibility,necessity and obstacles of integration of block chain technology and tax collection and management of natural persons in China.Finally,some practical suggestions are put forward for the implementation of the policy.
