Under Rule 50, if at the time of receipt of advance the nature of supply is not determinable, the supply is deemed to be an inter-State supply and IGST is payable.
However, while reporting such advance in GSTR-1, the system requires selection of the PoS (State) for interstate transactions.
If the nature of supply and consequently the actual place of supply is not determinable at the time of receipt of advance, which State should be reported in GSTR-1 for such advance liability?
