Letter of Undertaking (LUT) in GST

Export without paying IGST by filing an LUT.

About Letter of Undertaking (LUT) in GST

A Letter of Undertaking (LUT) lets exporters supply goods or services abroad, and to SEZ units, without paying Integrated GST (IGST) upfront. Without an LUT, an exporter would have to pay IGST on exports and then claim it back as a refund, which blocks working capital. By filing an LUT in Form GST RFD-11 on the GST portal at the start of each financial year, eligible exporters can zero-rate their exports and avoid this cash-flow strain. The LUT is valid for the whole financial year and must be renewed annually. We file your LUT promptly so your exports remain tax-efficient from day one of the year.
