An overview of GST Letter of Undertaking (LUT)

GST Letter of Undertaking

Exporters before the introduction of GST LUT had to submit an export bond for the purpose of exports. The export bond required money which became difficult for the exporters who are already short on liquidity. Keeping the genuine hardships of exporters in mind, the government came out with a concept of Letter of Undertaking where exporter promises to pay IGST on a future date.  

What is a GST Letter of Undertaking (LUT)?

A GST Letter of Undertaking is commonly known as LUT. LUT is a form that is prescribed for an exporter to be furnished under form GST RFD 11 under Rule 96A of the CGST Rules. It is nothing but a declaration from the exporter’s end that he will fulfil all the mandatory requirements that have been prescribed under the GST law while exporting without having paid IGST due on him.

Legal Framework of LUT

Filing of LUT is a mandatory requirement for an exporter while making exports of goods or services or both without making payments of Integrated Goods and Services Tax (IGST). If the exporter does not take the route of LUT, then the exports can only be made through payment of IGST or by furnishing an export bond.   

Before the introduction of LUT, the exporter only has the option of export bond. Realising the need of increasing ease of doing business, the government came up with a concept of LUT. Initially, LUT was supposed to be filed at the respective GST office physically by the exporter but now, the government has taken this process of filing LUT online. The exporter can now file LUT online through his respective account in the GST portal by the following the below mentioned steps.

Eligibility for filing LUT

Every GST registered exporter of goods or services or both are eligible for the benefits of LUT except those exporters who have been prosecuted for any offence of tax evasion whose value exceeds Rupees 250 lakhs under CGST Act or IGST Act[1] or any other law.

It must be noted that those exporters who are not eligible for filing LUT for exports, then the only option left with them is to furnish an export bond.

The motive of the government behind introducing the facility of LUT was to expand the export base and provide relief to the exporters.

  1. The person wish to export goods or services or both.

However, if because of any of the abovementioned reasons, the exporter forfeits the benefits of GST Letter of Undertaking, he can still avail the benefit of export bond.
