Goods and Services Tax (GST) is an indirect tax system introduced in India on 1st July 2017. It replaced many old taxes like VAT, service tax, excise duty, and others. GST made the tax system simpler and more transparent. Under GST, businesses that export goods or services have special benefits. One of the most important benefits for exporters is the facility of LUT in GST.
Export goods and services without paying IGST upfront. Learn what LUT in GST means, who can file it, documents required, and the step-by-step online process — all in one place.
LUT in GST stands for Letter of Undertaking — a declaration filed by registered exporters under the GST regime that allows them to export goods or services without paying Integrated GST (IGST) at the time of export.
Under Section 16(3) of the IGST Act, 2017, exporters are given two options — either pay IGST and claim a refund later, or furnish an LUT/Bond to export on a zero-rated basis without tax payment. Filing an LUT is almost always the smarter choice as it preserves working capital.
