TDS

This is the case relating to non-deduction of TDS.In case if we have not deducted TDS on RENT PAID , but subsequently we idenfied the non-deduction after 6 months.

During the six month, TDS rate is amended and new TDS rate came into force.

Can we deduct the TDS at the previous rate on the old bill value (onwhich no TDS is deducted) and at a new rate on the current rent payment in one current bill?

Can we do so in reality??
