Simplifying GST LUT Form: Essential Guide

The Letter of Undertaking (GST LUT form) under Goods and Services Tax (GST) allows eligible exporters to supply goods or services without paying Integrated GST (IGST) upfront. Submitting the GST RFD-11 form on the GST portal removes cash-flow bottlenecks and eliminates the need for a bank guarantee.

This guide explains every stage of the GST LUT application process—eligibility checks, documentation, GST LUT online submission, GST LUT renewal online, and common pitfalls. By following the steps below, you can complete your application with confidence and keep your exports IGST-free all year.

What Is a GST LUT Form (GST RFD-11)?

A GST LUT form is an online declaration that exporters file in lieu of paying IGST on outward supplies. Technically called Form GST RFD-11, it is submitted once a year on the GST portal. When approved, the LUT lets you export without blocking working capital in tax refunds. Only GST-registered taxpayers meeting the GST LUT eligibility criteria may file it.

The application requires e-signing a self-declaration in the prescribed GST LUT declaration format and listing two Indian witnesses. Once granted, the LUT remains valid for the entire financial year—this is the official GST LUT validity period. Timely renewal is essential to avoid IGST on future export invoices.

GST LUT Eligibility Criteria

Any exporter of goods or services registered under GST can apply, provided no prosecution for tax evasion above ₹2.5 crore has occurred in the last five years. Special Economic Zone (SEZ) units and developers also qualify for filing an LUT without bank guarantee. Separate applications are required for every distinct GSTIN under the same PAN, and branches in different states must file individually.

If you fail to meet these criteria, you may export under a bond with bank guarantee instead. Annual renewal before 1 April is compulsory to keep IGST-free benefits active.

GST LUT Validity Period & GST LUT Renewal Online

A sanctioned LUT is valid until 31 March of the same financial year. File your renewal in March to enjoy uninterrupted IGST-free exports from 1 April. Missing the GST LUT filing due date forces exporters to pay IGST and later claim refunds—an avoidable cash-flow hit.

Cost of Filing GST LUT & Service Options
