We have a valid LUT Number. Ours is 100% export unit and we are filing GSTR-1 without payment of tax. We are not paying any IGST on export sales and whatever GST (ITC) we have paid on packing material and other services related with export is refundable within two years from the date of export. There are certain annexures to be filed for GST Refund. Can anyone send me the format of the annexures on my mobile number 982 1630 130 or on my email id trconsulttax@gmail.com.
