Today this article will focus on “What is Letter of Undertaking under GST?”, Process for filling LUT under GST, Documents required for LUT under GST, and Eligibility criteria for filing LUT under GST (Goods and Service Tax).

What is Letter of Undertaking under GST?

Exporters might use a letter of undertaking to export products or services without paying taxes. All exports are subject to IGST under the new GST system, which can later be reclaimed via a refund against the tax paid. Exporters can avoid the hassle of seeking a refund and avoid the blockage of cash through tax payments by using a LUT (Letter of Undertaking).

Eligibility criteria for filing LUT under GST

All GST-registered exporters of goods and services must file a GST LUT. Exporters who have been charged with a crime or committed tax evasions totaling more than INR 250 lakhs under the CGST Act, the Integrated Goods and Services Act of 2017, or any other applicable legislation are ineligible to submit a GST LUT. They would need to provide an export bond in these circumstances.


Any registered person may submit an export bond or LUT under GST RFD 11 in accordance with the CGST Rules, 2017 without having to pay the integrated tax. They may apply for LUT if;

  • They are GST-registered and plan to provide goods or services to India, other countries, or SEZ (Special Economic Zone).
  • They want to sell items without having to pay the integrated tax.
