Simplify Your Export Business with GST Letter of Undertaking

A GST Letter of Undertaking (LUT) is a declaration submitted by an exporter to the GST authorities, allowing them to export goods or services without payment of integrated tax (IGST). By submitting an LUT, the exporter commits to fulfilling certain conditions, including bringing foreign exchange into India within the stipulated time period. This mechanism enables exporters to maintain better cash flow by avoiding tax payment at the time of export and subsequent refund claims.

Eligibility for submitting an LUT extends to all registered taxpayers who intend to export goods or services without payment of IGST, except those who have been prosecuted for tax evasion exceeding ₹250 lakhs. Status holders certified by DGFT under the Foreign Trade Policy automatically qualify, while other exporters must have a good compliance history with no tax defaults. Manufacturers and service providers exporting to specific countries like Nepal and Bhutan must use LUT even if they choose to pay IGST on other exports.

The key difference is that an LUT is a self-declaration without requiring any financial security, while a Bond requires bank guarantee or surety. Previously, only specified categories of exporters could use LUT, with others required to submit Bonds, but current regulations allow most exporters to use LUT. LUT is valid for a financial year, whereas Bond validity depends on the security amount. LUT processing is generally simpler and faster than Bond processing, making it the preferred option for eligible exporters.

Key obligations include receiving export proceeds in convertible foreign exchange or Indian rupees (where permitted) within the time limit specified under Foreign Exchange Management Act (typically within 9 months), maintaining proper records of exports made under LUT, reporting such exports correctly in GST returns (particularly in GSTR-1 and GSTR-3B), and paying applicable tax with interest if export proceeds are not received within the stipulated time. The exporter must also comply with all provisions of the GST law and fulfill any conditions specified in the LUT acceptance.

If LUT conditions are not fulfilled, particularly if export proceeds are not received within the stipulated time, the exporter becomes liable to pay the IGST that would have been applicable on the export, along with interest calculated from the date when the export was made. Repeated violations may result in the exporter being barred from using the LUT facility for future exports, requiring them to use Bond with bank guarantee instead. Non-compliance may also trigger departmental audits or investigations and affect the exporter's compliance rating under GST.

LUT benefits exporters by improving cash flow since they don't need to pay IGST upfront and then wait for refunds, eliminating the need for financial security or bank guarantee that would be required with a Bond. It simplifies compliance with a one-time submission valid for the entire financial year, reduces working capital requirements that would otherwise be blocked in tax payments, and streamlines the export process by avoiding documentation related to tax payment and refund claims. This mechanism makes Indian exports more competitive in the global market by reducing transaction costs.
