How to file Letter of Undertaking Online for Export in GST Form RFD?

Letter of undertaking is filed in Form GST RFD 11; It is also known as LUT. Filing of LUT is mandatory in order to export goods or service without payment of tax. In case the exporter has not furnished the LUT then he has to either pay the IGST on the goods or services exported or furnish an export bond.
