I have entered into a collaboration agreement with a builder to build a three storied house by demolishing an old house in a South Delhi colony on a plot measuring about 600 square yards. According to the agreement I will retain the ground floor and second floor with terrace rights, the builder will take the first floor and pay me Rs 5 lakh. How is the capital gains tax calculated in such a case? How much should I invest in government bonds so that I need not pay capital gains tax?Atul, Delhi
