hiii,

A payment was made on 8/10/2012 but forgot to deduct TDS and the same was deducted and deposited on 5/12/2013 without the interest payment.

Now a notice has been received from the department for payment of interest. Kindly advice whether the interest calculation is to be made till Dec'12 or till date.
