Exporters legally reduce the initial payment of GST on their inputs by making use of the Zero-Rated Supply provisions under the law of GST.
The two main techniques :
Export under Letter of Undertaking (LUT): The exporter posts an LUT (or Bond) with the GST authorities so that they can make the ultimate export without depositing Integrated GST (IGST). This way, their working capital is not frozen by the amount of tax. The GST previously paid on inputs (Input Tax Credit or ITC) is subsequently recovered as a refund.
Concessional Purchase Rate: Exporting merchants can ask their Indian suppliers to levy a substantially lower GST rate of 0.1% on goods acquired for the explicit purpose of export. This offsets the tax on the original purchase itself directly.
Indian exporters are presented with the perfect option to evade the payment of GST when they buy from local vendors. This is because, as per the current GST framework, the zero-rated supply provisions are available. They can decide to go either by way of a Letter of Undertaking (LUT) or a bond, which are documented exports, or by an export with an IGST refund.
Exporters can face big problems with their working capital when a GST amount is paid upfront on procurement before exports. By organizing the transactions through the use of India's zero-rated supply provisions, the exporters would be able to recover the taxes on inputs, or to totally void the upfront tax, thus, they will raise their liquidity and competitiveness.
Improved cash flow: GST 2.0 reforms make refunds more accessible and timelines shorter, thus reducing the waiting period for the return of working capital.
Reduced compliance burden: The LUT route helps in reducing the number of papers compared to IGST refund claims, thereby making the operational efficiency better.
Section 16 of the IGST Act, 2017, defines exports as zero-rated supplies. This section prescribes Zero-Rated Supply as supply to Special Economic Zones (SEZs) and exports.
The basic logic is to exempt Indian exports from the levy of domestic taxes ("tax-free exports"). This is done through two alternatives extended to the supplier:
Importantly, ITC can be claimed even if the last supply is zero-rated.
In layman's terms, exporters can do either of two legal things:
The company should submit annually a Letter of Undertaking declaring compliance with GST export regulations. The company can buy products from Indian suppliers and pay no IGST.
Working capital can be retained, and fewer refund documents will be required.
The company can file a claim for Input Tax Credit (ITC) on the purchases that are made to support exports of goods/services, which are actually zero-rated.
Usually, refunds are given out very fast; 90% provisional refunds can be issued shortly after the export acknowledgment.
First things first, get yourself registered with GST as an exporter.
The latest update in September 2025 GST rationalizes the Tax system, which overcomes the basic price, and streamlines the compliance of the exporters.
The rate cuts on manufacturing inputs and essential items are directly decreasing the exporter's expenses.
The government's efforts to introduce the refund process are turning working capital into a source of India's export competitiveness worldwide.
The fundamental concept of exporting under GST is zero-rating, where the final exported products or services are exempt from tax, and taxes incurred on inputs (Input Tax Credit or ITC) are returned. The most optimal method for an exporter to prevent GST on initial purchases is to supply without the payment of IGST by providing a Letter of Undertaking (LUT).

India’s post-2025 GST changes aim at supplying new energy to export-oriented industries and, consequently, to the economy by:
Exporters in India can either avoid the payment of GST on inputs followed by export by depositing a bond/obtaining LUT or swiftly recover the GST paid by utilizing the enhanced IGST refund routes. The utilization of working capital in the affairs of the company is hence made possible, and the export process is accelerated.
By leveraging the Letter of Undertaking (LUT) under the zero-rated supply provisions, exporters are legally entitled to receive goods from Indian suppliers without paying IGST, thus eliminating the blockage of working capital and minimizing the paperwork related to tax refunds.
In short, businesses have gained from recent GST 2.0 reforms, such as quicker refunds, the use of provisional credit, and the availability of simplified compliance. The exporters of India can utilize the liquidity to offer competitive prices, which will elevate their stature in the global markets. The letter of undertaking (LUT) route is, therefore, the most financially and operationally advantageous way by far for the majority of the authorized exporting agents in India, providing them with a hassle-free process, coverage throughout the year, and reduced administrative costs
Q1. What is "Zero-Rated Supply" under GST for Indian Exporters?
Zero-Rated Supply refers to the fact that while exporting goods or services from India, the GST rate charged is zero. This is not an exemption, but a legal requirement that all input taxes (GST paid on local procurements or services availed for export) are completely offset. This is done either by not paying IGST in advance (through LUT/Bond) or by claiming a full refund of the IGST paid.
Q2. How is Export under LUT different from claiming an IGST Refund?
They are the two lawful methods of dealing with Zero-Rated Supply:
LUT/Bond: You export without remitting IGST on the final exported product. You get to keep your working capital right away. You then claim a refund of the Input Tax Credit (ITC) paid on raw materials/services. This is usually the most cash-flow conducive method.
IGST Refund: You are charged IGST on the final export item. Your Shipping Bill serves as your application for a refund, and the refund is normally credited promptly (often 90% provisional refund) against the IGST charged on the export.
Q3. Which is a better route for a new exporter: LUT or IGST Refund?
The Letter of Undertaking (LUT) mode is usually preferred for optimal cash flow and the least amount of compliance. By not availing of IGST in advance, you retain funds and the related administrative work of seeking a refund of IGST of the final product. You need to claim ITC only on your inputs.
Q4. How long is the LUT/Bond valid?
The Letter of Undertaking (LUT) will normally be valid for a financial year. It should be filed and sanctioned electronically on the GST portal before the commencement of the financial year (or before the first export in the year) to maintain continuity of the zero-rated status.
Q5. Can I claim the Input Tax Credit (ITC) if I export under a Letter of Undertaking (LUT)?
Yes, certainly. This is an important advantage. Under LUT export, you pay no IGST on the final product but are still able to claim the refund of the ITC you incurred on all the goods and services that have been used to manufacture or supply the exported product.
Q6. What are the documents necessary for an immediate IGST refund?
The two most important documents are:
Q7. Need the supplier to do anything differently when selling to an exporter under LUT?
Yes. The Indian supplier, when they receive a copy of the exporter's valid LUT, will have to issue a "Supply for Export Under LUT" invoice, which charges zero (0%) IGST. They will have to report this transaction properly in their GSTR-1.
