Cenvat credit accumulation

Anoop (CA Final) (330 Points)

25 September 2014  

dear experts,

If a company during construction phase, i.e., having no commercial operations, pays service tax on capital assets acquired + ST under reverse charge mechanism.   

Subsequently after 2-3 years on completion of construction, on commencement of operations:  
1. can the cenvat credit paid i.r.of capital goods be accumulated.?   
2. most importantly, in cases where a substantial amount S.T is paid on consultancy fees, can that be deferred for utilization, once the commercial operations commence..?  

 Thanks and Regards,
