17 March 2018  

A flat bought in 1981 was sold in 2018.

Can the LTCG be invested in the following manner to get "complete" capital gains exemption?
1. Purchase of a new flat with 75% of the sum received
2. Purchase of capital gains bonds with 25% of the sum received
 

Secondly, is this investment to be made before Mar31,2018 or before the return filing date to claim exemption in AY2018-19?
