To answere the question the relevant fact as to why the bike was given as gift is to be clarified first .............was it as sales incentive to customers or to employees or there was other reasons????
The proviso to section 194B states that in case where the winnings are wholly in kind or partly in cash and partly in kind but the part in cash is not sufficient to meet the liability of deduction of tax in respect of whole of the winnings, the person responsible for paying shall, before releasing the winnings, ensure that tax has been paid in respect of the winning.
Having said so i do agree to the fact that it is necessary to determine why Gift was given.
