I understand the Long Term Capital gain from selling house can be invsted in 54EC bonds within 6 months to avoid taxes. I also heard about a provision called Capital Gain Savings Account can be opened to explore the possiblity of investment like new house etc and can be parked there for 3 years. Assuming I park the money in the Capital Gain Savings account and after a year I don't find properrty can I be allowed to invest the amount in 54 EC bond and allowed to claim excemptio?.
