The tax system of actually is the basis for government revenue by which the funds raisedrnwill provide opportunities throughout the economy for development and growth. Strong taxrnsystem, in turn, requires more than anything else timely and complete information as onernof its prerequisites. The lack of information can slow down the efficiency of taxation andrnthis in turn has impact on the process of national development.rnWhile rapid access to accurate information is critical to the tax operation, in the Ethiopianrntax system, there have been reports that access to information was difficult and has been arnpersistent problems for a long time. Such problem has also been prevalent at Region J 4rnFinance Bureau which is the case area of this studyrnMost of the information required for tax related activities are obtained based on searchesrnacross several files of taxpayers. The fact that the information is not readily available andrnmust be extracted from files increase the response time for action and increase the risk ofrnerror due to lost or misplacement of original documents. These circumstances pose furtherrndifficulties which deter the chasing of tax arrears.rnThis study, therefore, was undertaken to address the tax information handling problems inrnthe Region J 4 Finance Bureau, with the view of exploring the application of the featuresrnand capabilities provided by objects-oriented techniques in tackling the information accessrnproblemsrnSurvey instruments, consisting of questionnaire, interview as well as documentaryrnanalysis, were used to collect required data for the study. Analysis made on the basis of therndata gathered revealed enough evidence to establish the weaknesses of the existing taxrninformation handling. The analysis has also helped in pinpointing the system's requirementrnas well as identification of possible solution.rnAs one alternative solution for tackling the problems in the existing manual system,rndevelopment of a computer based database system is identified. In this connection, anrnattempt is made to demonstrate the application of object-oriented development techniques (rnas an appropriate technique ) to develop a database through prototyping. Further,rnrecommendations are made for considerations by the Bureau to fully benefit from thernsolution suggested by way of identifying the prototype database into fully operationalrndatabase.
