Hello dear,
In this case first of all there is transfer of capital asset therefore we have to check wether there is capital gain or not.
1) In the hand of the deceased ( A father ) transfer is an exempted transfer under section 47
(no treatment for transfer)
2) In the hands of Mr A we have to check the applicability of following sections
-section 49(1) which provide COA( i.e cost to the previous owner) in case transfer of capital asset without consideration and period of holding will be taken from the day when his father bought the asset ( not given by you)
assuming if purchased before 01/04/81 ( FMV being lower than purchase price) as per sec 55(2)
and please note for the purpose of head capital gain both land and building are seprate asset because
land is non depreciable, any capital gains/loss will be calculated as per provision of section 48
and
Building is deprecialble capital asset, capital gain/loss will be calculated as per section 50(1) & (2)
so it can aslo be said if A is taking land with building under same block and providing dep it will be wrong
and at the time of sale we have to check the applicability of sec 50(c)
since your full value of consideration seems to be lower than Stamp duty value, Stamp duty value will be take as full value of consideration.
and capital gain on land will be calculated as per provision of section 48 and gain or loss will be long term here fvc will be 2 crore
indexation will be done for the year when asset was first held by assessee
In case of builing gain or loss will be short term .... sec 50(1) & 50(2) here FMV will be 1.5 crore
In case there is unabsorbed depriciation due to business loss it can be carried forwrd without any limit. and u can check section 54 for exemption of capital gain :)
hope it will give you some idea
Thanks
