Gaurav as the interest U/s 234C is levied for default of payment of tax on the income which you have earned if you dont have any income then no need to tax as there will be no liability. Now come to an example. if you have earned STCG in 3 Qtr then how you can pay that tax in 1st & 2nd installment of Adv tax. your need to pay your tax after u came to know of adv tax liabilty. when there isno liabilty no need to pay tax.

intt U/s 234B is levied for late payment of Adv Tax so STCG will not affect the interest because as er this section 100% adv tax is required to p\be paid till 31 Marchif you not pay the tax then you will required to pay
