Sir, When you are using the word reversal it appies only when the credit is not available on account of various grounds i.e.
1. Capital goods removed as such
2. Capital goods wrritten off or provision has been made to write off
3. Capital goods removed after use
4. capital goods removed as scrap.
If it is the case, the cenvat credit has to be reversed. If there is no balance in the CENVAT credit (Capital goods) A/C, then such amount should be reversed from CENVAT credit (Inputs) A/C. If that is also not available then you have to pay the amount through PLA/GAR-7 challan. Such amount should be debited to asset account and the asset balance will increase, where we can claim depreciation as per AS-6.
Suppose if you are speaking about utilisation of credit during the second year then the provision shall be as follows:
At the time of purchase you will be transferring the amount (i.e 50% which can be utilised) to CENVAT credit deferred A/C. Now you have to canel this account by debiting the CENVAT credit receivable A/c, so that it can be adjusted for payment of Excise duty/ Service tax liablity.
I didnt understand about the internal accounting problem in your company. Can you please elaborate this so that i can help you to some extent
