GST LUT Form: A Comprehensive Guide for Exporters

Last Updated on September 17, 2026

The GST LUT (Letter of Undertaking) form is a necessary compliance requirement for exports in India. The GST LUT online filing makes exporting exempt from tax. Without paying IGST, you can fill out a form and ship products without questions while maintaining compliance with GST. In this guide, we cover what GST LUT is, its advantages and standing, supporting documents, its beneficiaries and application process, renewal, little-known points for exporters to consider, and potential mistakes to avoid.

What is LUT under GST?

A Letter of Undertaking (LUT) is a required certificate under India’s Goods and Services Tax (GST) system for exporters to ship goods or services without charging Integrated GST (IGST). The certificate is essentially a signed commitment by the exporter to comply with all the required GST provisions, along with a promise of dispatching shipments within the required timeframe. The LUT has to be furnished to the relevant GST office or filed online through the GST portal. With a LUT, exporters are not required to bear the immediate cash burden of tax payments and later claim refunds. The document is especially beneficial for companies that undertake frequent export transactions since it simplifies compliance procedures and enhances cash flow. The LUT is valid for one financial year and has to be renewed every year. In the absence of LUT, the exporters have to pay IGST, which will later be claimed, thus multiplying both administrative and financial difficulties.

A Letter of Undertaking (LUT) provides that the exporter may export goods or services without any advance payment of Integrated Goods and Services Tax (IGST) in respect of such exports and also claim refunds subsequently. Therefore, it gives a great deal of flexibility for exporters to export goods without paying such taxes in advance and claiming them through the assessment process as appropriate, just by submitting a LUT. This facilitates duty-free exports and improved cash flows through fewer compliance requirements.

Who Should File GST LUT?

Businesses wishing to export without paying IGST must file the GST LUT form. This encompasses firms of all stripes: manufacturers and traders, as well as traders supplying goods or services overseas. Whether SEZ exporting goods or services, compliant Suppliers of deemed export (e.g. those sold to SEZs), or exporters dealing with international organisations or embassies in natural mechanism. Nonetheless, from today onwards now in full Year-round activity

It is crucial that businesses who do not file LUT incur the cost of upfront IGST deductions in cash and lost productivity. By filing LUT, businesses can ease the burden of compliance and enjoy better cash flow: a prerequisite for surviving in today’s market.

Which Entities are Eligible to Apply for LUTs?

The following types of exporters are allowed to file a LUT under the Goods and Services Tax (GST) regime:

1. Registered Taxpayers Involved in Exports – Any person or entity registered under GST who is engaged in exports of goods or services can apply for an LUT. The LUT should be furnished before the export of goods or services.
2. Companies Exporting Under Zero-Rated Supply – Organisations exporting goods or services under zero-rated supply without paying IGST can benefit from this option. This includes direct exports and supplies to Special Economic Zones (SEZs).
3. Suppliers to SEZ Units/Developers – Local suppliers supplying goods or services to SEZ units or developers without the payment of IGST are entitled to file a LUT.
4. Deemed Exports (In Certain Cases) – Deemed exports are those transactions in which goods do not physically leave India but are treated as exports under GST law. Some types of deemed exports can be eligible to file a LUT.

Who is Not Eligible to File for LUT?

1. Businesses that primarily provide goods or services meant for local consumption and are not involved in exports or supply to Special Economic Zones (SEZs) are not eligible to apply for a LUT.
2. Exporters who have been charged with tax evasion, which means those individuals or entrepreneurs who have been prosecuted for tax evasion of ₹250 lakh or more, are not eligible to file a LUT. These businesses must submit a bond instead.

How to File GST LUT Online?

• Logging in at the GST portal: Visit the official GST portal at http://www.gst.gov.in. Log in with your username and password. Navigate to ‘Services’, access ‘User Services’, then click on ‘Furnish Letter of Undertaking (LUT)’.
• Choose Financial Year: You’ll need to file for a LUT in the section that’s relevant to that financial year. Getting the year right is essential to avoid processing errors. Any inaccuracies here can result in rejection or unnecessary time lags in exporting.
• Entering Business Details: The next step is to input business details. You must be the (GST) Registered Exporter. In addition, a self-declaration must be accepted, which confirms compliance with GST laws.
• Submitting Supporting Documents: The LUT document must be uploaded in PDF format and signed by an authorised person of the company. Attention must be paid to ensuring that the document is correctly formatted and matches business details. For example, supporting documents could be business registration certificates, PAN details and previous LUT filings-if applicable.
• Submitting with Digital Signatures: After filling in the required details, the LUT must be signed using a Digital Signature Certificate (DSC) or Electronic Verification Code (EVC). Once submitted, an acknowledgement message is generated, or you are assigned an ARN (Acknowledgement Reference Number). The ARN is used as proof that submission has been made and should be kept for future reference.
• Downloading and Storing LUTs: After submission, the exporter should download and store a copy of the LUT for future reference and review purposes. When checking anything arising from IMDRF, as shown above, it is beneficial to have the record Dip like this to provide elaboration or approval in the event counsel from GST authorities ever comes calling.

Before applying for LUT, exporters must obtain a valid GSTIN, as only registered taxpayers are eligible to submit LUT applications.

Before proceeding with exports, businesses should also ensure they have completed IEC registration online, as an Import Export Code (IEC) issued by the Directorate General of Foreign Trade (DGFT) is mandatory for carrying out international trade activities in India. Having both an active IEC and a valid LUT helps exporters operate smoothly and remain compliant with regulatory requirements.

To get a Letter of Undertaking (LUT) as per the Goods and Services Tax (GST) regime, exporters have to furnish certain documents affirming their eligibility and compliance standards. The LUT application can be filed online via the GST portal or, if required, offline by visiting the concerned GST office.

Documents Required for LUT Application

Validity and Renewal of GST LUT

The GST LUT is valid for one financial year. Exporters must renew it before expiry in order to continue making tax-free exports. Failure to renew may result in mandatory IGST payment on imports until a fresh LUT is filed.

The LUT renewal process is best done proactively, preferably a few weeks before expiry, to avoid disruptions in export operations. Enterprises should keep track of their LUT’s validity and ensure timely submission enforcement shall be smooth in all respects.

Benefits of Using LUT

Using a LUT allows exporters to increase operating efficiency, decrease expenses, and focus on international growth. Exporters who employ an LUT benefit from competitive leverage by promoting easier transactions and obtaining higher fiscal efficiency in foreign trade.

1. Relieves cash pressure by allowing exporters to avoid payment of Integrated GST (IGST) on goods and services.
2. Improves Cash Flow by eliminating the need to pay taxes in advance and wait for refunds, resulting in more liquidity.
3. Facilitates Regulatory Compliance as it reduces documentation and eliminates the complexity involved in filing IGST refund applications.
4. Streamlines the Export Process by allowing faster customs clearance of goods without any tax-related delays.
5. Cost Effectiveness because it helps exporters to save unnecessary costs associated with tax payment and refund procedures.
6. Increases Global Competitiveness, thereby facilitating better pricing of Indian goods and also improving the overall image of Indian exports at the world level market.
7. One-Year Validity: Once approved, the LUT is valid for the whole fiscal year, thus minimising the number of compliance checks.

Common Errors and Solutions

• Incorrect Financial Year Selection: Choosing the incorrect financial year while filing LUT will result in rejection. Accurate selection is essential. Exporters should check and double-check the year before submitting to ensure that they do not needlessly go down this path.
• Non-compliance with GST regulations: Exporters should file GST returns in a timely manner, as failure to comply can result in LUT rejection. It is essential to stay current on compliance. If an exporter fails to comply with the rules of GST, they may be subject to fines or receive a penalty from the authorities or even see increased restrictions on any future export transaction.
• Document Inconsistencies: Errors in documentation can result in longer processing times. In order to avoid rejection of the uploaded LUT the uploaded LUT should precisely match business info.

To avoid such problems, all documents, including the GST patch, business registration certification and earnings papers, should be consistent.

Important Things to Note about LUT Submission and Renewal

1. In order to guarantee tax-free exports from April 1, 2026, the LUT must be renewed by March 31, 2026.
2. The LUT holds good for a period of one financial year, i.e., from April 1, 2026, to March 31, 2027.
3. Approval Process: In general, immediately after online filing, subject to the requirement for additional verification.
4. Consequences of Non-Compliance: Not filing an LUT requires exporters to pay IGST and claim a refund.

By following this process, companies can easily renew their LUT for FY 2026-27, thus maintaining zero-rated exports without the burden of taxes.

Consequences of Not Filing LUT

Failing to file an LUT means that export IGST has to be paid before a product is exported. That can delay returning money that’s been paid on IGST, tying up working capital.

Moreover, such non-compliance may bring penalties or written notice from the tax authorities. For businesses that are heavily export oriented, not refiling LUT may bring both economic pressure and administrative errors into their production process.

Key Considerations for Exporters

Exporters should get to the LUT website for re-filing LUT before the close of the financial year. Exporters are sure to want these invoices as proof of exports, GSL transport sheets or labour contracts signed for every transaction by ship and truck loaded from the ship at berth. There is a need to watch carefully for all favourites long taken on trading through a modern network model

As the GST rules and regulations change and operative guidelines have unexpected minor twists or turning points, traders need to be well informed. Regular consultation with professional tax accountants or GST experts makes it possible for businesses to stay ahead of the compliance cycle.
