I exported services in Dec by paying IGST, and filed GSTR-01showing Sales under Exports 6A.
However, I applied for LUT only in February.
I also tried filing a Refund application RFD 01-A for the same, but an error stating 'No outward supply tax filed for the selected return period' is being displayed.
So, how exactly should I claim Refund on the IGST paid?
