Rule 4(7) of CCR 2004 is self explanatory as the same specifies the period of 1 year for the purpose of availment of CENVAT Credit in respect of any of the document issues under Rule 9. In case of reverse charge, CENVAT Credit is admissible on the basis of TR-6 challan as and when the tax is paid.
Hence, period of 1 year commences from the date of payment of Tax under reverse charge. Furthermore, where the Service Tax has been paid under reverse charge and CENVAT Credit has been availed within a period of 3 months from issue of invoice date, but the payment has not been made within 3 months, CENVAT Credit needs to be reversed or paid back. The same may be reclaimed when the payment has been made to supplier and henceforth period of 1 year limitation does not apply.
