After furnishing all details in the form, click Surrender ST-2. The assessee would be required to take a print out of the form that appears and submit the same to the Superintendent with a covering letter as well as Original ST-2.
The superintendent may check the books of the assesee to ascertain that all service tax has been duely paid by the assessee and no amount is payable by the assessee to the department. Obtaining a certificate from a Chartered Accountant in this regard may also help stating that no amount is due.
