LUT Filing (Letter of Undertaking) is a declaration that allows exporters to supply goods or services without the payment of Integrated GST (IGST). By filing an LUT, eligible taxpayers can export without upfront tax payment, thus improving liquidity and cash flow. LUT must be filed at the beginning of each financial year on the GST portal and is available to businesses that have not been prosecuted for any serious tax offenses in the past. GST Refunds apply in various scenarios, such as excess tax paid, unutilized input tax credit (especially in cases of inverted duty structure or zero-rated supplies), and IGST paid on exports.
