This discussion clarifies the Goods and Services Tax (GST) liability for advance payments made to Goods Transport Agencies (GTA) and advocates under the Reverse Charge Mechanism (RCM). While RCM liability generally arises on the date of payment, the key question is how to report these transactions in GSTR-1. The consensus is that when GST is paid, it must be declared, although the specific column for reporting advance RCM payments in GSTR-1 requires further clarification.
