A Letter of Undertaking (LUT) is a vital document under the Goods and Services Tax (GST) law in India that allows exporters to supply goods or services without paying Integrated GST (IGST). Instead of paying tax upfront and later claiming a refund, businesses can file an LUT and export tax-free, making the process faster and more efficient.
The main purpose of the LUT is to ease the financial burden on exporters by eliminating the need to block working capital in tax payments. By filing this document with the GST department, exporters commit to complying with all GST regulations during exports. This facility is especially beneficial for businesses engaged in regular export activities, as it streamlines cash flow and reduces compliance costs.
Any registered taxpayer exporting goods, services, or both can file an LUT to enjoy zero-rated exports without paying IGST. However, businesses previously prosecuted for tax evasion above ₹250 lakh cannot use this facility. Filing LUT annually ensures uninterrupted benefits and is a key step for exporters to maintain smooth, tax-free export operations.
