Businesses involved in exports often hear about GST LUT Registration, but many are unsure about what it actually means and whether they need it. Without an LUT, exporters may have to pay Integrated GST (IGST) on exports first and then apply for a refund, which can impact cash flow and increase compliance efforts.
A Letter of Undertaking (LUT) offers an easier alternative. Eligible exporters can export goods or services without paying IGST upfront, helping them manage working capital more efficiently while remaining compliant with GST regulations.
This guide explains what GST LUT Registration is, who can apply, the required documents, the registration process, and the common mistakes to avoid.
What is GST LUT Registration?
A Letter of Undertaking (LUT) is a declaration submitted by eligible exporters under the GST law. It allows them to export goods or services, or make eligible supplies, without paying Integrated GST (IGST), subject to the applicable provisions and conditions.
Instead of paying IGST and later claiming a refund, eligible taxpayers can furnish an LUT and continue exports without the upfront tax payment.
