DESIGN AND IMPLEMENTATION OF A COMPUTERIZED TAX EVALUATION SYSTEM FOR CIVIL SERVANTS
(A CASE STUDY OF BOARD OF INTERNAL REVENUE)
ABSTRACT
          It is often easy to collect data about objectives of persons. However subsequent processing of such data presents problems especially when it involves numerous computations and retrieval of information.
          In the manual processing of large volumes of data too many mistakes can be made and much time wasted because of the ardors and cumbersome nature of associated tasks.
          This project is aimed at the design and implementation of tax evaluation system, for civil servant which will store all relevant information of a client, automatically processing the information of a scored generated document which the free pay allowance and tax due  for the client, retrieve and display relevant information with regard to the client’s tax evaluation.
The system has been designed to cater for the tax evaluation of employees in the Nigeria Civil Service, but it can be expanded to take care of other kinds of employment with very little modification.

INTRODUCTION
 1.1    BACKGROUND OF THE STUDY
          In the past, people have become used to machine built to perform a specific purpose, for instance, the typewriter can produce neat work, a musical instrument can produce a certain type of sound e.t.c. However computer does all these things, often more efficiently than the specific purpose machine mentioned above, hence we say that computer is a general purpose machine.
          Computer is probably best introduced on the basis of its purpose, which is data processing. Processing of data into information. Data is known as the raw materials on which a computer operates. There are facts recorded about people’s daily activities such as in business, science, education, government and other forms of organized human activities or endeavours. When some appropriate structures have been applied to data it becomes information.
          The use of computer in the area of tax evaluation recently has been seriously emphasized to the extent that both civil servants and the tax evaluators find way of using computer to solve most of taxation problems. Therefore this project tends to, design and implement a tax evaluation system for civil servants. It helps in eradicating the problems encountered in tax evaluation of civil servants by the Board of Internal Revenue Enugu, such as lack of uniformity of database, lack of up-to-date records of workers’ tax payment in the board, delay in supplying of information about worker’s, inconsistency of data items and time wasting.
 1.2    STATEMENT OF PROBLEM
          The major difficulties faced by evaluation department in the Board of Internal Revenue Enugu, are lack of uniformity of civil servants’ data-base in the board, lack of up-to-date record of civil servants, delay in supply of information management and information sharing, inconsistency of data items and time consuming in tax evaluation system in Enugu.
 1.3    PURPOSE OF THE STUDY
          The purposes of this study are:
(i)       To eradicate or minimize the problems encountered
(ii)      To computerize the manual method of processing
(iii)     To aid for easy processing of civil servants file with high level accuracy.
(iv)    To reduce errors in processing of the workers file.
(v)      To reduce the very large volumes of paper work.
 1.4    SIGNIFICANCE OF THE STUDY
          Computer has gained an available position in many spheres of human endeavours and every sector not yet touched by this vogue is struggling to catch up with the evolution.
          The introduction of computerized tax evaluation system for civil servants in Enugu is thus justified by three major benefits namely:  
(i)       It will eliminate all kinds of errors encountered in processing workers (civil servants) file.
(ii)      The staff in evaluation department will have more time for other tax assessment work in the department.
(iii)     There will be more confidence in computer generated result than that compiled by the staff which are more often suspicions as human being are prone to error and bias,
 1.5    SCOPE OF THE STUDY
The study of tax evaluation system for civil servants is quite an elaborate undertaking. Owing to certain factor that militates against a wholesome precaution of such an elaborate study, the researcher limits this study to the evaluation or assessment department in Board of Internal Revenue Enugu.
 1.6    ASSUMPTION
          It is assumed that the information giving by the staffs in the evaluation department in Board of Internal Revenue Enugu are true and it will help us in achieving our purpose of this research.
