if deductor forget deduct tds on any payment to contractor(in Q3 2013-14)which is a singal transaction in that period. but he recall that in next quarter.
in that case whether deductor should file Tds return Q3 or consider it in Q4 return.
i think for that we should file Q4 TDS return with payment of interest Of 1% (in case of forgot)deduct TDS.
