They incurred Rs.300000/- for modification cost for the Flat in financial year 2001-2002. The flat was sold in financial year 2010-2011 at Rs.14/- lacs. Part payment received in financial year 2010-2011 and balance received in financial year 2011-2012.What would be the gain and tax payable. How to save tax by depositing fund in govt.bond. Kindly help me so that the Govt. bond can be purchased in financial year 2011-2012 itself before 31/March. Thanks, mkrpillai.
