Transfer of funds into an external platform would not result in any profit/gain as it involves only transfer of funds to self. Further no transaction has been undertaken / executed resulting in any transfer of any asset.
Any foreign remittance by resident individuals under Liberalised Remittance Scheme (LRS) framed by RBI may trigger TCS (Tax Collection at Source) provisions which requires collection of tax at 5% (10% in case of non-PAN / Aadhar cases) where the total foreign remittance including the transfer of funds exceeds INR 7,00,000 per annum. In this regard, transfer of funds into Stockal platform by way of foreign remittance may attract TCS.
Please note that this is not a tax liability.
