We receive quarterly advance payments from our members to whom we provide maintenances services. Service tax is applicable on these receipts. We also take the Cenvat Credit of these services which we have outsourced it to different agencies. The credit period for payment to these agencies is 30 days so the payments for service for April will be made on 31st May or 1st June. But we have collected the advances from members for April May June in the month of April.What is our Service tax laibility as on 30th April (for the month of April only or for the full quarter) secondly I would get the Cenvat credit for the same service in the month of May or June. So how do I adjust the two. Will I have to make the service tax payment for April since no Cenvat is available in April
