A company bought a piece of land on 29.07.15 for Rs. 40 lakh, it then entered into a joint development agreement on 01.08.15. Now on 1.4.17 the building is constructed and the land owner company gets 70% of constructed area. The stamp value of constructed area is 2 crore. Stamp value of land as on date of agreement was 45 lakhs..
Now in which year capital gain would arise?!.
What will be the sale consideration for the company!?
