I had sold a house in May 2008 and in Nov 2008 purchased a residential plot. After indexation Calculation no capital gain tax was not there and I was told that I should build a house on this plot within three years. Now I want to sell this residential plot (no house has been built on it yet) and buy a built up house instead. What shall be the whole situation with regard to Capital Gain tax in the first transaction and the second transaction. Please help
