Designated authorised dealer requirement ensures remittance routing, account vintage, source documentation and Form A-2 declaration for compliance. Remitters under the Liberalised Remittance Scheme must route capital account remittances through a single designated branch of an Authorised Dealer, maintain the remitting bank account for the prescribed minimum period, and, for new customers, submit enhanced due diligence including the previous year's bank statement or Income Tax Assessment Order/Return to verify source of funds. Remitters must furnish Form A-2 declaring the purpose and ownership of funds and confirming funds will not be used for prohibited or regulated purposes under the Scheme.
