Non Payment of Advance Tax

One of my friend has only Capital gain income for the AY 2018-19. And it's not long term. It's kind of speculation. He has not paid any Advance Tax for the AY. What is the consequences of non payment of Advance Tax ? He suspects that his tax liability crosses the limit of Rs. 10,000. He wants to pay the entire tax liability before July 31st while filling Return of Income. Is it only the payment of interest or is there any Criminal liability for non payment of Advance Tax.?
