Advance money forfeiture: post-change forfeitures taxed as income to seller, pre-change forfeitures reduce asset cost for capital gains. Forfeited advances received in negotiations for transfer of a capital asset reduce the cost of acquisition, fair market value or written down value for capital gains computation if forfeited before 01.04.2014; forfeitures on or after 01.04.2014 are taxable to the seller as Income from Other Sources and are not deductible from the asset's cost. Buyer-side forfeitures generally do not qualify as capital loss; extinguishment of rights (e.g., forfeiture of shares for non-payment of calls) can give rise to short-term capital loss.
