Enactment of Goods and Service Tax has set up the goal of simplifying the tax implications and processes by facilitating portal for GST return filing. Centralised processes and portals are developed to administer the matters by single authority for taxes on commodity and services. In same manner for transactions within state, goods and services are dealt outside Indian boundaries. Discussing about creating market place outside India by trading products in other countries, exporting plays major role, which activity is continuously promoted by the Government of India for betterment of country.

In this regards, exporting from India may be routed in two ways for the purpose of exports. Export by payment of taxes applicable and claiming refund at a later stage in manner provided. The alternate to this is export without paying tax by furnishing the letter of undertaking (LUT) to the concerned authority. Here, we are discussing about what the letter of undertaking is and upcoming changes in the system.

In case the entity wants to choose second way, they are required to furnish an undertaking to the Government. The Letter of Undertaking (LUT) is prescribed to be furnished in form GST RFD 11 under Rule 96A, whereby the taxpayer (exporter) declares that he shall fulfil all the requirements prescribed under GST for this route on exports.

Unless the letter of undertaking is filed by the exporter, he shall make payment of GST applicable on goods or services being sent to importer. The eligibility criteria to furnish Letter of Undertaking are relaxed and to every person to export goods can choose this route, unlike to previous applicability where the condition of foreign inward and turnover was prescribed. Filing Letter of Undertaking will be mandatory to export goods or service or both without payment of Integrated Taxes (IGST). If the same has not been furnished, the export can only be made through payment of IGST on goods or service or both, as may be applicable.

    It is a very nicely written article about Letter of Undertaking ( LUT). I was looking for information on the same. It is good that GST Network is providing facility to furnish the LUT through online portal nowadays which was not the case earlier.

    Would supplies effected still qualify as exports if an entity inadvertantly didn’t furnish LUT
