Pankaj, Please see if you can help out on this. A commercial property was acquired in Nov 2005 for Rs.4 lakh and sold in Apr 2012 for Rs.8 lakh. i.e LTCG of 4 lakhs. I have reinvested the gains of Rs. 4 lakhs into a new residential house which is currently under construction and will be ready by end 2012. Currently, I am owning in two adjoining 1BHK flats which have been combined but is actually one house with a single kitchen and common entrance, but registered as two units. Q1- Am I eligible for reinvesting the amount to buy a new residential property, as I have one house only, but registered as two? Q2 - Is 8 lakhs or gain of 4 lakhs to be invested? If I need to invest 8 lakhs, can I put the diffference into a capital gains bond instead of putting into the new house? Q3 - Is there any need to show these calculations in the income tax returns?
