I would only partly agree with Vishal. I studied your case law. It has as specific proviso for Interest u/s 234C stating that:
"
Provided that nothing contained in this sub-section shall apply to any shortfall in the payment of the tax due on the returned income where such shortfall is on account of under-estimate or failure to estimate--
(a) the amount of capital gains; or
(b) income of the nature referred to in sub-clause (ix) of clause (24) of section 2, and the assessee has paid the whole of the amount of tax payable in respect of income referred to in clause (a) or clause (b), as the case may be, had such income been a part of the total income, as part of the1[remaining instalments of advance tax which are due or where no such instalments are due], by the 31st day of March of the financial year:]
"
Although the income earned by the assessee in business income, nevertheless you cannot deny that the nature of such income is "capital gains" and one cannot predict the accrual of such income.
Although, I will have to say that, Such interest would not be payable only if the entire amount of tax was paid by 31-3-2015.
Further, interest u/s 234B has to be calculated after the calculation of interest payable in accordance with sec 234C. Hence, where no interest under section 234C arises, sec 234B interest would also not be attracted.
Therefore, if the assessee has duly paid the Basic Tax on MAt income on or brfore 31-3-2015, no interest under 234 B and C would arise.
