Dears,

In our case we are calculating tax under sec 44AD as special business and tax comes to 30000/-. In our Tax calculation software  interest under sec 234 B & C are not calculated  why? in our software interest under sec 234B & C are calculated only when the income is taxable at normal rates. Is it correct or not? please quote the relevant section also?
