With that capital gain ,I am about to buy another house ,but as this capital gain money is not sufficient to buy and needed more money, and We are still in process to get money. Registration of new house is not done and will happen after all money is given to seller.
Problem is March is coming what should I do for tax submission.
No need to worry, till return filed for AY 2019-20. If amount not paid to purchase new house, deposit the gains amount to CGAS, 1988 account of any nationalized bank.
