The above table consists of tax slabs for persons who are above 60yrs who are termed as Senior Citizens. I would like to explain the calculation of tax here.
In the first slab a relaxation up to Rs.2, 50,000 is given to Senior Citizens so no tax I levied up to Rs.2, 50,000 for them.
Coming to the second slab where the total income exceeds Rs.2,50,000 but does not exceed Rs,500,000 then the tax is 10% of the amount by which the total income exceeds Rs.2,50,000 but does not exceed Rs.5,00,000 i.e. if suppose the income is Rs.2,60,000 then the tax is Rs.2,60,000 * 10% which is Rs. 26,000.
Coming to the next third slab where the total income exceeds Rs.5,00,000 but does not exceed Rs10,00,000 then the tax calculated is as follows i.e. if suppose the income is Rs.5,50,000 then the tax calculated is Rs.25,000 which is taken from the previous slab and then 20% of the amount which is exceeded by Rs.5,00,000, here the amount which is exceeded by 5,00,000 is Rs.50,000 so the tax is Rs.25,000+50,000*20%=Rs.35,000.
Coming to the fourth slab where the total income exceeds Rs.10,00,000 the tax is calculated as follows Rs.1,25,000à(5,00,00010,00,000=5,00,000*20%=100,000 taken from 3^{rd} slab+25000 taken from 2^{nd} slab) plus 30% of the amount which exceeds Rs10,00,000 i.e. if the income is Rs10,50,000 then the tax to be paid is 1,25,000+50,000*30%= 140,000.
