234c interest - mat vis-a-vis capital gains

No, Advance tax liability arises even if the total income contains capital gains....so no deduction for the same for computing Interest u/s 234B and 234 C.

Question is posted now clearly...earlier it was not.....

as per first proviso to sub-sec (1) of section 234C, interest will not be applicable, if any shortfall in the payment of tax due is on account of under-estimate or failure to estimate the amount of capital gains..

According to me, profit on sale of asset included in books profits cannot be reduced while calculating Interest under section 234C. This is because the section mentions the word "Capital gains". Profit on sale of asset is covered under the head "Profit on Business/profession". The same is not specifically covered by section 234C.
