Service tax input

If it qualies as capital goods as per defiition , credit can be availed in the year 11-12. But without a proper invioce credit cannot be taken.
 

Thanks Mr Unnikrishan... it is an eligible capital good and the same has proper invoice...

Any other document necessary to support our claim both to Department and Auditors

No other document is required

Dear friend

Credit of Capital goods and input materials always can be taken as when material is received in your premises and not depends upon the payment.

So if the invoice is cancelled then either  you would not get the delivery or you will be issued other invoice as the case may be. If Asset is not delivered then there is no question of cretit availment
