Abstract

Over the past 10 years there has been many Tax software developed by software houses specifically customized to meet their client’s needs (Tax Consultants). However none of them has really answered the need for a system which is user friendly, multi-users, and secure. From our research most of the Tax Software developed in Indonesia has usually abandoned the Graphical User Interaction (GUI) layout. The layout of the buttons, menus, and input boxes are not well organized and can be confusing for new user. Second, although some of the new Tax Software developed already support multi-users capability, most of them still do not support it or only have partial support. Third, most of the Tax Software are developed using an old and traditional programming language such as DBASE, FORTRAN, DELPHI, and C. These old programming languages usually suffer from attack such as “buffer overflow” attack.

essential because we can visually develop our application from page design, debugging at run-time, database management, creating procedures in your database, and many other features. Visual Studio.net provides all those features without the need of third party tools that is why it is very convenient for the developer because they will not need to switch back and forth from one application to another application because Visual Studio.net has provide most of the functionalities which are frequently used.

Objectives

Our main objective in creating this thesis is to offer a breakthrough solution in existing Tax calculation system. This will overcome the previous system weakness which included massive data-input processing and unfriendly user interface. Our end-result system will simplify the process and reduce the workload since most of the process will be done in client side thus reducing server workload. This will enable faster processing and better quality deliverance.

Method

We are going to develop our application in two areas. First is by using traditional windows application system for internal usage which is only accessible by company’s staff. Second is by developing web application as an interface to interact with existing customers. This web application will be used for data delivery purpose and it will then be integrated with the internal windows application system.

Results

The result of this two system development is satisfaction by both customer and tax consultant who processes their yearly income. Customers now will need less time to get response from submitted data which can be used for them as analysis for their financial aspect and will give them longer to for preparation. Secondly all paper based report from both customers and tax processors can now be converted into soft-copy form thus reducing expense and space.

Conclusion

In conclusion hopefully this new system will bring great benefit to every aspect involved. By introducing new technology into traditional IT system, much benefit will be gained. One of the weaknesses in IT infrastructure in Indonesia is not up to date with the technology released. This habit of maintaining old infrastructure proved to be even more costly than restructuring the whole system using a more up to date technology. We hope that by introducing this new .NET technology which is very famous in Europe and US already, we will be motivated to give the best.
