Advance tax in case of mat

Adv tax is paid on estimated future income and MAt is caluclated at flat rate of 18.5% on book profit.....pls reframe ur question as 2 are diffrent issues

If my estimated future income is Rs.10 lac & I claim 80IB 100% Deduction 3rd year & while calculating MAT @ 18.5% on estimated book profit of Rs.10 lac then I have to pay 18.5% of 10 lac i.e.1.90 lac X 30 % Advance Tax = Rs.57,000/- as on 15-12-12  is this correct.

it should be 10lacs * 60% as advance tax for corporate assessee as its the 2nd due date for advance tax andalso refer section 205-210 and sec 234B n 234C
