Sir,
Rule 4 (7) of CENVAT Credit rules, 2004 provides that the CENVAT credit in respect of input service shall be allowed, on or after the day on which the invoice, bill or, as the case may be, challan referred to in rule 9 is received.
However proviso to this rule provides that in respect of input service where whole or part of the service tax is liable to be paid by the recipient of service, credit of service tax payable by the service recipient shall be allowed after such service tax is paid.
The second proviso to the above rules provides that in case the payment of the value of input service and the service tax paid or payable as indicated in the invoice, bill or, as the case may be, challan referred to in rule 9 is not made within three months of the date of the invoice, bill or, as the case may be, challan, the manufacturer or the service provider who has taken credit on such input service, shall pay an amount equal to the CENVAT credit availed on such input service, (except an amount equal to the CENVAT credit of the tax that is paid by the manufacturer or the service provider as recipient of service), and in case the said payment is made, the manufacturer or output service provider, as the case may be, shall be entitled to take the credit of the amount equivalent to the CENVAT credit paid earlier subject to the other provisions of these rules
