LUT Full Form GST Mein — Matlab aur Kise Chahiye

  • In summary


    A Letter of Undertaking (LUT) lets eligible GST-registered exporters of goods or services make qualifying exports without paying Integrated Goods and Services Tax (IGST) upfront, subject to the conditions under GST law. This can help you preserve working capital instead of waiting for a refund after paying tax.


    • An LUT is generally used by eligible exporters making supplies without payment of IGST, including qualifying supplies to a Special Economic Zone (SEZ).
    • File the LUT online through the GST portal before making the relevant supplies, and retain the acknowledgement and Application Reference Number (ARN).
    • An LUT generally applies for the financial year in which it is furnished, so you need to submit a fresh one for each financial year.
    • If you are not eligible to furnish an LUT, a bond may be required. Check the current rules and your circumstances before filing.

    The details below are intended to help you plan the export process. Eligibility, documentation, deadlines, and consequences for non-compliance depend on the applicable provisions and your transactions; confirm them on the GST portal or with a qualified tax professional.

What is a GST LUT?

  • An LUT is an undertaking furnished by an eligible registered taxpayer to export goods or services, or make eligible supplies to an SEZ, without payment of IGST, subject to the prescribed conditions. It is submitted online through the GST portal. If you do not qualify to furnish an LUT, you may need to provide a bond instead.


    For an exporter, the key practical benefit is cash flow: you do not have to pay IGST upfront on qualifying supplies and then wait for a refund. The LUT does not remove other export-related requirements, such as issuing appropriate invoices, maintaining records, and meeting the conditions for a supply to qualify as an export.

When should you apply for an LUT, and what was the process before GST?

  • You should furnish an LUT before making qualifying exports without payment of IGST. The current process is online through the GST portal. Before this online process was introduced, exporters used a manual process involving the prescribed form and submission to the relevant authorities, which could add time and administrative effort.


    A bond is different from an LUT and may involve non-judicial stamp paper and additional security requirements. Check the current process for your case rather than relying on older manual instructions.

Eligibility criteria for LUT registration

To furnish an LUT, you generally need to be registered under GST and intend to make qualifying exports of goods or services, or eligible supplies to an SEZ, without payment of IGST. Eligibility is subject to the restrictions set out under the applicable GST rules.


A person prosecuted for tax evasion involving an amount of Rs. 2.5 crore or more may not be eligible to furnish an LUT and may need to provide a bond instead. Verify the current legal threshold and its application to your circumstances before relying on it.

Documents required for GST LUT registration

  • GST registration certificate: Keep a copy of your GST registration details available.
  • Authorised signatory identification: Keep the identity details required for the person signing the application.
  • Authorised signatory details: Have the authorised signatory’s Permanent Account Number (PAN) and, where you are filing for a business entity, the authorisation that permits the person to act on its behalf.
  • Previous LUT, if applicable: Keep a copy of the previously accepted LUT for reference.

For step-by-step guidance on accessing your registration details, refer to GST certificate download. Before applying, check your business loan eligibility if you are also planning funding for export operations; the loan application requirements are separate from the documents needed for an LUT. 

The jurisdiction for submission of an LUT

The relevant GST jurisdiction is generally linked to the taxpayer’s registration and principal place of business. However, the LUT is furnished online through the GST portal rather than by routinely submitting it to a local office in person. Use the portal’s current workflow and follow any instructions shown for your registration.


For estimating tax on relevant transactions, you can also use a GST calculator, while confirming the correct tax treatment under the applicable rules.

Validity of an LUT

An LUT generally remains valid for the financial year in which it is furnished. If you want to continue making eligible exports without payment of IGST in the next financial year, you should furnish a fresh LUT.


The export and payment conditions attached to an LUT also matter. Goods should generally be exported within three months from the invoice date and that payment for exported services should generally be received within one year from the date of the LUT, subject to the applicable provisions and any permitted extensions. Where conditions are not met, tax and interest may become payable, and the LUT facility may be affected.


Because statutory timelines, extensions, and consequences can depend on the transaction and current rules, confirm the relevant time limits before acting.

Step-by-step process to file an LUT in GST

  • Log in to the GST portal using your taxpayer credentials.
  • Navigate to the LUT filing option for the relevant financial year and open the prescribed form.
  • Enter the required details, complete the declarations, and review the information before submission.
  • Sign and submit the application using the verification method available to your taxpayer type, such as a Digital Signature Certificate (DSC) or Electronic Verification Code (EVC), as applicable.
  • After submission, save the acknowledgement and the Application Reference Number (ARN) for your records.

Check that the authorised signatory is correct and that the information matches your GST registration. Keep the acknowledgement with your export records so your team can retrieve it if questions arise.

Who can sign the LUT application

The application should be signed by the primary authorised signatory or another person authorised to sign on behalf of the taxpayer, such as a proprietor, working partner, managing director, or another duly authorised person. The accepted signing method depends on the type of taxpayer and the portal requirements; companies and limited liability partnerships may be required to use a DSC.


After submission, retain the ARN and download the acknowledgement. These records help you demonstrate that the LUT was furnished and provide a reference if you need to follow up on the application.

Status of an LUT application on the GST portal

The portal may display different statuses as an application progresses. Some examples are:


  • Submitted: the application has been filed.
  • Pending Clarification: a clarification has been requested.
  • Pending Order: a response has been submitted, or the response period has passed, and an order is awaited.
  • Approved: the undertaking has been accepted.
  • Rejected: the undertaking has not been accepted.
  • Deemed Approved: the application is treated as approved under the applicable process when the authority does not act within the prescribed time.
  • Expired: the LUT validity period has ended.

There is a three-working-day period for deemed approval. Verify the current portal rules and status definitions before relying on a specific timeline.

Advantages of filing an LUT for exporters

  • Cash flow: You can avoid paying IGST upfront on qualifying exports, helping preserve funds for payroll, suppliers, production, and other operating costs.
  • Simpler refund administration: Using an LUT can avoid the need to pay IGST first and then seek a refund for eligible exports, although other refund or compliance processes may still apply.
  • Operational planning: A valid LUT and organised export records can help your finance team plan invoices, filings, and supporting documents.
  • International competitiveness: Preserving working capital may help you manage pricing and delivery commitments in overseas markets.

Exploring the LUT bond

A bond is an alternative for an exporter who cannot furnish an LUT but wants to make eligible exports without payment of IGST, subject to the applicable rules. A bond may require a financial security or bank guarantee and can involve additional documentation. The precise conditions depend on the case, so confirm the requirements before choosing this route.

LUT vs bond: key differences

An eligible exporter can generally furnish an LUT online, while an exporter who does not qualify may need to furnish a bond. The main differences are summarised below.


FeatureLUTBond
Who can use itEligible registered exporters who are not barred from the facilityExporters who are not eligible to furnish an LUT
FormatUndertaking submitted online through the GST portalBond document; non-judicial stamp paper and related formalities may apply
Financial securityGenerally no bank guarantee is required for an LUTA bank guarantee or other security may be required, subject to the applicable rules and case

Do not assume that a single security percentage or processing timeline applies to every bond. Ask a tax professional to confirm the requirements for your export activity.

Timeline for LUT or bond processing

Furnish an LUT before making the qualifying supplies for which you intend to use the facility, and allow time to resolve any portal issues or requests for clarification. A bond may require additional steps, including execution on the required stamp paper or provision of security. Processing time depends on the application, the documents submitted, and the applicable procedure.


Once an LUT is furnished, save the acknowledgement and check the portal for the relevant status. Avoid relying on a fixed number of working days unless the current portal guidance confirms it for your case.

Contents of a Letter of Undertaking

The LUT application generally records the exporter’s details and the undertaking to comply with the conditions under GST law. Be ready to provide or confirm the following information where requested by the portal:


  • Exporter’s name and principal place of business.
  • Goods and Services Tax Identification Number (GSTIN).
  • The applicable financial year or validity period.
  • The required declarations and undertakings under GST law.
  • Details and signature of the authorised signatory, along with the date and place where required.
  • Witness details if requested by the current form or process.

How to apply for an LUT in GST

To apply, log in to the GST portal, open the LUT form for the relevant financial year, complete the declarations, sign using the method applicable to your taxpayer type, and submit it. Download the acknowledgement and retain the ARN with your business records. If the portal requests clarification, respond within the stated time and keep a copy of your response.

Manage export cash flow and business growth

For an exporter, avoiding upfront IGST on qualifying supplies can help preserve working capital, but you still need to fund production, shipping, payroll, supplier payments, and other operating expenses. Build your cash-flow forecast around export receipts, GST filing dates, and the annual LUT renewal so that compliance tasks do not disrupt day-to-day operations.


If export orders, production costs, shipping, or delayed customer payments put pressure on your working capital, you may compare external funding with your forecast cash flow and repayment capacity. Bajaj Finance Business Loan offers loan amounts from Rs. 2 lakh to Rs. 80 lakh and repayment tenures from 12 to 96 months, subject to eligibility, approval, and applicable terms. The available options include a Term Loan, Flexi Dropline Loan, and Flexi Hybrid Loan.


Before starting an application, check your pre-approved business loan offer. A loan is optional and should be considered only if the repayment schedule fits your business’s expected cash flow.

Frequently asked questions

Overview

Who needs to file a GST LUT?

A registered taxpayer who exports goods or services, or supplies to a Special Economic Zone, and wants to do so without paying IGST needs to file a GST LUT. 

Is a GST LUT mandatory for all exporters?

No. A GST LUT is not mandatory for every exporter. It is a facility that lets a registered exporter supply without paying IGST. The other route is to pay IGST on the export invoice and claim a refund later, which keeps funds blocked until the refund comes. An exporter who is not eligible for an LUT has to furnish a bond to export without paying tax. Ask a tax professional which route suits your business.

Can I file a GST LUT for software exports?

Yes, if you are registered under GST and the supply qualifies as an export of services. A software company serving a client abroad may furnish an LUT and export without payment of IGST, provided the supply meets the statutory conditions for an export of services. These include the required supplier and recipient locations, place-of-supply conditions, and receipt of payment in convertible foreign exchange or in Indian rupees where permitted by the Reserve Bank of India. Confirm that your particular service and transaction qualify before filing.

How many witnesses are needed to file a GST LUT?

Two. As per one guide, the form asks for the name, occupation and address of two independent and reliable witnesses, who should not be connected with the business. These details are needed when you file the LUT for the first time. Check the portal for the current requirement before you file.

Can a GST LUT be filed offline?

No. As per one guide, an LUT is now furnished only online through the GST portal. A bond is different, because it is submitted on non-judicial stamp paper and may involve manual processing. After you file the LUT, download the acknowledgment with the ARN and keep it as proof.

Can a freelancer or consultant file a GST LUT?

Yes. Any person registered under GST who exports services can file a GST LUT, including a freelancer, a consultant or a small business with clients abroad. The person should not be barred by a prosecution for tax evasion of Rs. 2.5 crore or more. The LUT lets the invoice be raised without IGST, and a fresh LUT is needed for every financial year.
