Hello sir,

This is regarding TDS and long term capital Gain tax for sale of house property. I bought house in 2009 and sold in 2016. The long term capital gain on this sale is around 6 lacs. the trans details are

Agree for sale  - 29/02/2016

TDS deducted -  12/03/2016                        Rs. 570000

Sale deed         -23/05/2016

Capital gain       - 6 lacs

Agreement of this sale done in last FY and sale deed on this FY. I have to deposit the capital gain in CGtax saving scheme.

I need clarification tht whether I have to deposit the CG before july 31st of 2016 and file return or  I can do it before next year return file date (31/07/2017) as sale deed done in 23/05/2016. Which date I have to considered, TDS date or sale deed date.
