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.

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.
