🧾 What is a GST LUT?

A Letter of Undertaking (LUT) is a declaration that allows exporters to supply goods or services without payment of IGST, under Rule 96A of CGST Rules.

Instead of paying tax and later claiming a refund, LUT simplifies export compliance and improves cash flow. LUT must be filed annually before making zero-rated exports.
