Please note carefully, you should do deferintiate Salary person IT wise such as:-
a) Central Government & State Government Employees of any organisation may give more Tax and they must have less benefits under IT because they are having other source of income .
b) Small business man (1 - 20 Lacs) have some other tax benefits as they are also having other source of income.
c) Private sector employees may under less IT rules as they are getting No. 1 income & do not have any other source of income. These people are most harrased. Because they are have to work harder & harder to stay in pvt. co. & do the performance. If you tax them heavily then how they sustain.
Because now days everything is going against there limits like house rent, conveyance, eatables etc
