I have registered my flat for 22 lakhs in 2017, now sold it in august 2021 for 78.3 lakhs. I have registered another new flat in feb 2021 for 56 lakhs . Can I avail complete LTCG exemption on 78.3 lakhs ? is the new flat cost should be more or equal to LTCG value or it should be same as total sale price of old property to avail maximum tax exemption?
