Why we ask this
A Letter of Undertaking (Form GST RFD-11) lets exporters and SEZ suppliers make zero-rated supplies without paying IGST upfront and then claiming a refund. That keeps working capital free instead of locked up with the department for months. The LUT is filed on the GST portal once per financial year, so the GSTIN and the target FY drive which form is filed.
