The purpose of this paper is to consider the meaning of existence of Japanese Income Category System in Income Tax Act in recent years. The Japanese national tax system is based on the principle that“ Income” should be taxed. And taxable income of individuals is divided into some categories based on “Earning Capacity”. The amount of each of the categories of income is computed, and they are aggregated as“ Ordinary Income Amounts". This system was enacted in 1950's, so there is the separation of the taxation theory from the present business situations, and not always suitable. We should recognize the importance of responding to the changing business environment surrounding individuals' economic activities.
