Hi,
Your mother will have to pay tax on the capital gain earned by her on the land sold by her. If there is a capital gain loss, then there will not be any tax payable.
To calculate the amount of capital gains, the indexed cost of the land as on 1 April 2001 will be reduced from the sale consideration received on sale of the land. You can use the Registrar's value of the land as on 1 April 2001 to find the capital gain.
The indexed cost of land will be the value of the land as on 1 April 2001, multiplied by the inflation index for the year of sale 2017 (i.e. 272) and divided by the inflation index for 2001 (i.e. 100).
If you reduced this indexed amount from the sale consideration, then you will get the amount of capital gains that you have earned from the sale of the land. If there is a gain, then tax is payable. If there is a loss, then no tax is payable. There are cases, where there is a capital loss since we will be taking a assumed value as on 1 April 2001.
If you want to save tax, then you can invest in a residential property or invest in NHAI or REC bonds.
The amounts gifted by your mother to her children and grandchildren will be exempt in their hands.
Trust this clarifies.
