Dear Experts, My brother and sister are holding Stocks of various Companies from 1980s. They will be giving these Stocks to me by appropriate way either by Gift OR by transfer. And I am planning to sell/dispose it of in market immediately and its current market value are high. In this situation, will I be liable to pay Capital Gain Tax? Else, how do I have to receive these Shares from them if I have to avoid tax on selling of Shares. Regards.
