Property purchase and capital gain related query

Ideally, to save capital gains tax u/s. 54; your mother should purchase the property (or any other) from you or builder by way of registered agreement (with stamp duty paid), within 2 years from sell of the house property.

Thanks for your reply sir. it means if this newly purchase under construction property won`t complete in 2 years than we will have to pay capital gain tax after that?

First of your mother should be owner/co-owner of the property.

Once she has invested her shares in the property, and in case, the construction is delayed by builder; she can still claim for capital gain exemption. Various courts have allowed the exemption in similar cases where the situation had been beyond control of assessee.
