If TDS is deducted and deposited the same at the time of payment instead of against bill though the bill is received earlier then it will be any fault according to rule? also it has been observed that this process for deduction of TDS is being followed by our company for a long period. So should we change the mode of deductioin and payment of TDS. Will be there any Interest on TDS for not being deducted at the time of bill raised?
