Once ITC of compensation cess is validly availed under Section 16 of the CGST Act and utilised against output liability, there is no requirement to reverse the ITC merely because the Government has withdrawn compensation cess prospectively on those goods.
The withdrawal of cess applies from the date notified, and it does not retrospectively impact the eligibility of ITC already taken on stock purchased earlier.
Reversal obligation arises only if ITC is wrongly taken, or when goods/services are used for exempt supplies or non-business purposes [Section 17CGST Act]. Since the stock was purchased when cess was leviable, ITC was correctly availed.
Therefore, in GSTR-3B (GST-02), he should continue as usual – no reversal entry required.
Conclusion: You are not required to reverse the ITC of compensation cess already availed and utilised just because the cess has been removed later.
