Letter of Undertaking
Annual filing that lets exporters export without paying IGST.
LUT (Form RFD-11) is filed annually by exporters of goods or services. Without LUT, exporters must pay IGST and claim refund — wastes 60-90 days. With LUT, exports are zero-rated and ITC is refunded directly.
Every exporter — IT services, goods, software, online services to foreign clients.
