Overview

GST Letter of Undertaking (LUT) is a formal declaration submitted by exporters on the GST Portal allowing them to export goods or services without paying Integrated GST (IGST) upfront. By filing LUT using Form GST RFD-11 before the export, businesses avoid locking up working capital in tax payments and streamline export operations. It must be filed every financial year and is valid only if the exporter has no significant GST prosecution history or pending tax liabilities.
