A query needed to be solved urgently

@ Seena, Pay the amount with interest. Either you can pay it by separate challan or pay in this months challan. What is important is how you will represent the same in the service tax return, at the time of filing.

Now since,  you have taken the service tax credit by mistake on the same invoice, twice while calculating the s.t.duty liability  for the month of Dec, while preparing s.t. return, take the credit of that invoice only once for Dec. Which will lead to shortfall of payment made for the month of Dec 2012. Now, you should have made the payment before 6th of Jan (E-payment), but you are paying on 5th of Feb. i.e. you will have to pay interest for one month along with the shortfall amount and accomodate the same at the time of filing s.t.return

Hope the matter is clear.

Also if needed, wait for other's comment, to get more clarity.
