2. A concise response (within 2,500 characters) could be as follows:
In my view, the demand is not legally sustainable if it is based merely on the inclusion of foreign exchange fluctuation income in the GSTR-9C reconciliation. The amount represents notional accounting income arising from year-end restatement of foreign currency monetary items in accordance with AS-11/Ind AS 21. It is an accounting adjustment and not consideration for any supply of goods or services.
GSTR-9C requires reconciliation of turnover as per the audited financial statements with turnover declared in GST returns. Consequently, items such as foreign exchange fluctuation gain appearing in the Statement of Profit and Loss are disclosed only for reconciliation purposes. Such disclosure does not determine taxability under the CGST Act.
GST is leviable only on a "supply" under section 7 of the CGST Act. A notional foreign exchange translation gain does not involve any supply, consideration, or independent transaction with a customer. It merely reflects the impact of exchange rate movement on outstanding foreign currency monetary assets or liabilities as on the balance sheet date.
It is also important to distinguish between:
(i) realized foreign exchange gain arising on actual settlement of an underlying taxable supply, which ordinarily forms part of the value of that supply in accordance with section 15 read with Rule 34 of the CGST Rules, and
(ii) unrealized/translation gain recognized at the year end under AS-11, which is purely notional and does not arise from any supply.
The Service Tax jurisprudence has consistently recognized that mere foreign exchange fluctuation or accounting entries, in the absence of an independent service, do not constitute a taxable service. The same principle supports the GST regime since the charging event continues to be "supply" and not accounting recognition.
Therefore, if the amount reflected in GSTR-9C is purely an unrealized foreign exchange translation gain recognized under AS-11, it is only a reconciliation item and cannot be subjected to GST merely because it appears as "Other Income" in the financial statements. The reply to the notice should clearly explain the accounting treatment, distinguish realized and unrealized gains, and emphasize that no taxable supply has occurred.
