Below is the answer given by ICAI
As per Clause 16(b) of Form 3CD, the details of the Refund duty of custom, if admitted as due by the concerned authorities but not
credited to the profit and loss account, are to be stated. But the Credits/Claims which have been admitted as due after the relevant previous year need not be reported in Form 3 CD.
In the instant case, the action of T Ltd in not crediting the claim to the profit and loss account and also not reporting of the same in Clause 16(b) of Form 3CD is in order.
Further Clause 13(b) requires reporting when there has been any change in the method of accounting employed vis-a-vis the accounting method employed in the immediately preceding year. However, change in an accounting policy will not amount to a change in the method of accounting and hence such change in the accounting policy need not be mentioned under Clause 13(b). It may be noted that change in the method of valuation of stock will amount to a change in accounting policy. However, it should be disclosed in the financial statements.
