While filing GSTR3B of August 2017, zero rated supply (export sales) with IGST paid was wrongly entered under outward taxable supplies (other than zero rated supplies).
When I contacted the GSTN, they informed that GSTR3B can not be revised & you can rectify the same while filing the GSTR1. But now, for releasing the refund of IGST paid on Exports, new circular has come that the IGST amount as per GSTR3B, Table 6A & data as per Shipping bill should match each other.
So kindly advice how can we get refund on above case?
