Sir, I have sold a residential house for Rs.44,00,000/- in 2011 November. The plot was purchased in 1981 for Rs.1,00,000. House was constructed in 2010-11 and sold in 2011 November. How can I save the income tax. Should I purchase a residential house for the amount or can I purchase two different sites for the amount Rs.44,00,000/- or can I construct a house on a site which I already own.
