Design And Implementation Of Diversified Tax Declaration System

In this dissertation, the author has implemented a commerce tax and insurance declaration system based on Yunnan’s diverse land tax digital declaration systems. This system is based on OOP and J2EE, using B/S three (N) tier architecture, and can apply declaration using multiple methods including banks and the Internet. The system has user friendly interface, and is stable, complete and has trustable performance. The system satisfies the third phase objective of State Bureau of Taxation’s golden tax plan. Currently the system has smoothly gone live in the whole province and received excellent feedback.This dissertation introduces basic concepts of diverse digital declaration system and real world use cases both domestic and foreign. The author also analyzes tax payer’s detailed declaration situation, the requirement of Yunnan land taxation system, and business requirements of several commercial banks requirements carefully. After the analysis, the author made plans and combined various business and departments successfully. Then the author introduces related technologies and architecture used in the system. The system uses data aggregation systems built with J2EE stack, B/S three (N) tier architecture and browser technology. The system not only has guaranteed the unified standard of business and data processing, but also satisfies different department and faculty’s needs by flexible configurations. A complete, efficient, shared, tightly controlled and secure system is built. The principle of system design is dividing system into three parts according to the goal of implementation and function requirement:system management, configuration modification, trading control etc. The business part has implemented user authorization, tax declaration, audition, order put, discarding, account verification etc. The business part has implemented declaration information query, trading information query, public message querying etc. At the end, the author illustrates the implementation methods used by the diverse digital declaration system, and made future plans for next step of research.
