Short answerA LUT (Letter of Undertaking) lets an exporter ship goods or services without paying IGST upfront, instead of paying and then claiming a refund. You file it once a year on the GST portal (Form RFD-11) before exporting.
What an LUT does
It lets you export at zero-rate without blocking working capital in IGST that you’d otherwise pay and reclaim.
File yearly before exporting
Submit Form RFD-11 on the portal at the start of each financial year, before your first export of the year.
