This discussion explores whether investing long-term capital gains (LTCG) into an under-construction property, where full payment is made within six months but possession is delayed for over three years, qualifies for tax exemption under Section 54 of the Income Tax Act. Based on Madras High Court rulings, the focus is on the investment aspect rather than immediate occupation or possession. The key takeaway is that making the investment within the stipulated timeframe is crucial for claiming the exemption, even if the property isn't ready for occupation.
