One company has Short paid service TAX in APRIL 2014 of Rs 10,000.00 and it has excess paid of ST of rs 10500.00 in july .

The question is as follows : 

can the interest @ 18% for MAY & June will also be adjusted in July Apart form ST and same can be shown in ST3 return.

Please note when service tax paid ,  Account code has not been taken for any interest as that time  it is not required . can we adjust the interst even if initially only we have chose the service provider account code........ not the interest account code.
