17 July 2011  

 I entered into agreement to sell a landed property on 1-3-2011 and I received token money of 2 lakhs on 1-3-2011 . 

The total sale price is to be paid by purchaser by 31-03-2013 in 3 installments .

Registry to be done at 3rd instalment . There will be a capital gain of Rs.1.5 lakhs from sale .

My query is when will Capital gain become due to be paid -- now or after full payment is made or after date of registry ?
