Consideration for transfer in cases of understatement: fair market value may be adopted where related-party transfer or material understatement exists. Where the acquirer is connected with the transferor and the officer believes the transfer was made to avoid capital gains tax, the full value of consideration may be taken as the asset's fair market value on the transfer date with prior approval; similarly, a material understatement of declared consideration may justify treating consideration as fair market value, subject to specified exceptions for government transfers and values determined or approved by the Central Government or the Reserve Bank of India.
