you can calculate it yourself.
for income from 2.5L to 5L, its 10% of income,
for 5L to 10L its 20% share,
and above 10L its 30%.
Now, its calculated like this. eg. Suppose your income is 12L per year,
10% of 5L-2.5L = 10% of 2.5L = 25000/-
20% of 10L-5L = 20% of 5L = 100000/-
30% of 12L-10L = 30% of 2L = 60000/-
Now adding all three slabs i.e. 25000+100000+60000 = 185000/-
Means on 12L income per year you have to pay 185000 income tax.
