The fee charged for admitting a person as a member in an institution is called admission fee or entrance fee. It is paid only once by the member, it is not of a recurring nature and should not be treated as income. There is another argument that though each member pays it only once, the institution receives it every year when new admission take place.
Therefore, it can be treated as revenue income. Here again if there is specific instruction to treat the entire or a portion of the amount as capital the relevant amount should be taken to Balance Sheet.
