Pls let me know that I had taken service from vendor in the month of march 2013 and the vendor issued service tax invoice but the vendor not paid so far tax. Vendor is not registered in service tax and the vendor saying that the service tax input whatever we claimed earlier that amount should be paid to service tax cell on behalf of him by us it is correct procedure or else any procedure to pay service tax by us on behalf of vendor because we had claimed in put in the month of march 2013 and paid the balance tax.
