What is Letter of Undertaking (LUT) in GST For Exporters?

Imagine you’re an exporter navigating the waters of international trade. The Letter of Undertaking (LUT) in GST acts like a helpful guide, easing your journey. It’s a simple promise that lets you export goods without paying taxes upfront. It’s like a smooth path through the sometimes choppy seas of taxation, making your life easier as you ship your products worldwide.

What is the Letter of Undertaking in GST?

LUT stands for Letter of Undertaking, which serves as a document for exporters to facilitate the export of goods or services without the requirement of paying taxes upfront. With the implementation of the Goods and Services Tax (GST), all exports are subjected to Integrated Goods and Services Tax (IGST). However, exporters can reclaim the IGST paid through a refund process.

Many exporters encounter challenges in obtaining tax refunds, making alternative options like LUT highly appealing. By furnishing an LUT, exporters can bypass the need for tax payment and the subsequent refund process. This not only saves time and effort but also prevents funds from being tied up in tax payments.

The process of filing an LUT is straightforward and can be done online, offering exporters a hassle-free experience. According to the CGST Rules, 2017, any registered person can submit a bond or LUT in form GST RFD 11 to export goods without paying integrated tax.
