I have purchased residential flat (1 BHK) 10 years back at 20 lacs, now I am planning to sell at 65 lacs. Same time I will be booking a flat in same area (2BHK) which will cost me around 100 lacs. The new flat purchase agreement will happen in May, 2012. The possession of new flat is December, 2014. As per construction status of new flat I will be have to pay Rs. 40 lacs immediately and pending as per progress. Request you to let me know if this will attract any capital gain tax? 1. As I will be selling house in 2011-12 and purchasing new in 2012-13. 2. As per builder the possession will be in December, 2014, but I think it may be happen by March 2015.
