GST LUT Verification Details: Process, Status & Documents

GST LUT Verification Details: Process, Documents, Status and Common Issues

For businesses engaged in exporting goods or services from India, the GST Letter of Undertaking (LUT) is an important compliance requirement when exports are made without payment of Integrated Goods and Services Tax (IGST). An LUT allows an eligible registered taxpayer to undertake zero-rated exports without paying IGST upfront, subject to the conditions prescribed under GST law.

Understanding GST LUT verification details is important because an incorrectly submitted LUT, incomplete information, or a verification issue can create difficulties when maintaining export compliance or claiming eligible refunds of unutilised input tax credit.

This guide explains what GST LUT verification means, who can file an LUT, the information required, the online filing process, how to check the status, common verification problems, and important compliance points for exporters.

What Is GST LUT?

LUT stands for Letter of Undertaking. Under Rule 96A of the CGST Rules, a registered person who intends to export goods or services without payment of IGST may furnish a bond or LUT in Form GST RFD-11, subject to applicable requirements.

The LUT is essentially an undertaking by the exporter that the conditions associated with export without payment of IGST will be complied with. If the relevant conditions are not fulfilled, the tax and applicable interest may become payable in accordance with the GST provisions.

CBIC's Rule 96A specifically deals with exports of goods or services under bond or Letter of Undertaking.

What Is GST LUT Verification?

GST LUT verification refers to the process of validating and submitting the Letter of Undertaking through the GST system. During the process, the taxpayer provides the required undertaking and verifies the application using the applicable authentication method available on the GST Portal.

The purpose of verification is to establish that the LUT has been submitted by the registered taxpayer or authorised signatory and that the information furnished in the application is properly authenticated.

Depending on the taxpayer's constitution and the filing method available on the portal, authentication may involve Electronic Verification Code (EVC) or Digital Signature Certificate (DSC).

Why Is GST LUT Important for Exporters?

Exports are treated as zero-rated supplies under the GST framework, subject to the applicable conditions. An exporter may generally make eligible exports under LUT without payment of IGST and subsequently claim eligible refund of accumulated input tax credit, subject to the applicable refund provisions.

This can be useful for exporters because they do not have to fund the IGST amount on eligible exports and then wait for a refund of the tax paid on those exports.

CBIC's refund rules provide for refund of eligible unutilised input tax credit in cases involving zero-rated supplies made without payment of tax under a bond or LUT, subject to the prescribed conditions and formula.

Who Can File a GST LUT?

A registered taxpayer involved in eligible export supplies may use the LUT facility where the applicable GST conditions are satisfied.

Typical users of LUT include:

Exporters of goods
Exporters of services
Software and IT service companies
Consulting businesses providing services to overseas customers
Freelancers providing eligible services to foreign clients
Manufacturers exporting products outside India
Merchant exporters
Businesses supplying eligible goods or services to customers outside India

Whether a particular transaction qualifies as an export should be checked against the applicable GST provisions. Filing an LUT alone does not automatically make every transaction an export.

GST LUT and Export Without Payment of IGST

The main purpose of an LUT is to enable an eligible exporter to make qualifying exports without payment of IGST.

For example, assume an Indian software company provides eligible services to a customer located outside India. If the transaction qualifies as an export of services and the required conditions are satisfied, the company may furnish an LUT and supply the services without charging IGST, subject to applicable GST provisions.

The exporter can then follow the applicable refund process for eligible accumulated input tax credit.

GST LUT Verification Details Required

Before submitting an LUT, taxpayers should keep their GST registration and authorised signatory information ready.

Common information associated with LUT filing includes:

GSTIN
Legal name of the registered taxpayer
Business address
Details of the authorised signatory
Financial year for which the LUT is being furnished
Details required in the LUT undertaking
Witness details where applicable in the prescribed format
Digital authentication or electronic verification details

The exact fields and portal workflow may change as GST Portal functionality is updated. Taxpayers should therefore verify the current form and filing screens before submission.

How to File GST LUT Online

The GST LUT filing process is generally carried out online through the GST Portal.

Step 1: Login to the GST Portal

Step 2: Open the LUT Application

Navigate through the GST Portal to the section for filing the Letter of Undertaking. The exact menu labels may change with portal updates.

Step 3: Select the Financial Year

Select the relevant financial year for which the LUT is being furnished.

Step 4: Enter or Confirm the Details

Review the taxpayer and authorised signatory details displayed by the system. Enter the information required in the LUT application.

Step 5: Provide the Undertaking

The taxpayer confirms the undertaking prescribed under GST law, including compliance with the applicable export requirements.

Step 6: Add Witness Details Where Required

Where the prescribed form or portal workflow requires witness information, enter the relevant details carefully.

Step 7: Verify the Application

Complete the applicable verification process using the authentication method provided by the GST Portal.

Step 8: Submit the LUT

Submit the application after checking all details. Save the acknowledgement or ARN/reference generated by the system for future records.

GST LUT Verification Through DSC

Businesses that are required to use a Digital Signature Certificate should ensure that the DSC is properly registered and associated with the authorised signatory on the GST Portal.

Before filing, check:

Whether the DSC is valid
Whether the correct authorised signatory is selected
Whether the DSC utility or required browser component is functioning
Whether the certificate has expired
Whether the PAN details associated with the DSC are correct

A mismatch between the authorised signatory information and the digital signature can result in verification or submission problems.

GST LUT Verification Through EVC

Where EVC is available for the relevant filing, the taxpayer may authenticate the submission using the electronic verification mechanism provided by the GST Portal.

GST Portal guidance explains that EVC can be used for various forms, returns, statements and other filings for eligible categories of taxpayers.

The registered mobile number and email information should therefore be kept accessible during the verification process.

How to Check GST LUT Status

After submitting the LUT, the taxpayer should retain the acknowledgement/reference generated by the GST Portal.

The taxpayer can log in to the GST Portal and navigate to the relevant LUT section to review previously submitted LUTs and their available status or acknowledgement information.

Depending on the portal version and filing workflow, the terminology used for the status may change.

It is advisable to download and retain a copy of the submitted LUT and acknowledgement for the company's GST records.

What Does LUT ARN Mean?

ARN generally refers to the Application Reference Number generated by the GST system for certain applications and submissions.

When an acknowledgement or reference number is generated for an LUT filing, it should be preserved as evidence of the submission and used when communicating with the GST authorities or checking the filing details.

GST LUT Verification Pending

Sometimes a taxpayer may see a pending status or may not immediately find the expected acknowledgement after submission.

Possible reasons can include:

Temporary GST Portal issues
Incomplete submission
Authentication failure
Incorrect authorised signatory selection
DSC-related problems
Browser or technical issues
Portal processing delays
Incorrect information entered during filing

Before submitting another application, check whether the earlier submission was actually successful. Duplicate submissions can create unnecessary confusion in the compliance records.

Common GST LUT Verification Problems

1. DSC Not Detected

If the portal does not recognise the DSC, check whether the certificate is active and whether the required signing utility or browser configuration is working correctly.

2. Authorised Signatory Mismatch

If the person attempting verification is not properly registered as an authorised signatory, the filing may not proceed.

3. OTP Not Received

If OTP-based verification is available but the OTP is not received, check the registered mobile number and email address and confirm that messages from the GST system are not being blocked.

4. Incorrect Financial Year

Selecting the wrong financial year can cause compliance issues. Always review the selected year before final submission.

5. Technical Error on GST Portal

Portal-related errors may sometimes prevent successful submission. Taking a screenshot of the error message and recording the time of the attempted filing can be useful when raising a technical complaint.

GST LUT Validity

An LUT is generally furnished for a financial year. Exporters should therefore plan their LUT compliance around the applicable financial year and ensure that the LUT for the relevant period is furnished before making exports under the LUT route.

Businesses that regularly export should include LUT filing in their annual GST compliance calendar.

When Should GST LUT Be Filed?

The LUT should be furnished before making the relevant exports under the LUT facility. Rule 96A refers to furnishing the bond or LUT prior to export when the taxpayer chooses to export without payment of integrated tax.

Therefore, exporters should avoid waiting until after the first export transaction of a financial year to address LUT compliance.

What Happens If Export Conditions Are Not Met?

The LUT is not simply a formality. It contains an undertaking to comply with the applicable export conditions.

Rule 96A provides consequences where goods are not exported within the specified period or where payment for exported services is not received within the applicable period. The rule provides for payment of the relevant tax along with applicable interest, subject to the provisions and extensions that may apply.

For goods, Rule 96A refers to the specified export period from the date of invoice, while for services it refers to the applicable period for receipt of payment. Taxpayers should verify the current provisions for their specific transaction.

GST LUT for Export of Services

LUT compliance is particularly relevant for Indian businesses providing services to customers outside India.

Examples may include:

Software development services
IT support services
Digital marketing services
Accounting and bookkeeping services
Business consulting services
Design services
Engineering services
Professional services

However, merely receiving money from a foreign customer does not automatically make a transaction an export of services. The applicable conditions for export of services must be examined for each transaction.

GST LUT for Export of Goods

Businesses exporting physical products can also use the LUT mechanism where the applicable conditions are satisfied.

Export documentation should be properly maintained, including invoices, shipping documents, customs records and other relevant evidence.

CBIC's invoice rules specify that an export invoice where goods or services are supplied under bond or LUT without payment of IGST should carry the prescribed export endorsement.

Documents to Maintain After GST LUT Filing

Businesses should maintain an organised GST export file containing relevant documents such as:

Copy of the submitted LUT
LUT acknowledgement/reference
GST registration certificate
Export invoices
Shipping bills for goods exports, where applicable
Export-related agreements or purchase orders
Foreign remittance/payment records for services, where applicable
GSTR-1 records
GSTR-3B records
Input tax credit records
Refund applications and supporting documents, where applicable

Maintaining these records can make GST reconciliation and departmental verification easier.

GST LUT and GSTR-1

Export transactions should be correctly reported in the applicable GST returns.

Rule 96A also provides for electronic transmission of export invoice information furnished in GSTR-1 to the customs system for goods exports, along with confirmation of export being transmitted back to the common portal.

Therefore, businesses should ensure that export invoices reported in their GST returns are consistent with their shipping and commercial records.

GST LUT and GSTR-3B

Export turnover and input tax credit should also be appropriately reflected in the relevant GST return filings.

Differences between GSTR-1, GSTR-3B, books of accounts and export documentation can create reconciliation issues.

A monthly reconciliation process can help identify:

Missing export invoices
Incorrect invoice numbers
Incorrect taxable values
Incorrect GSTIN details
Unreported credit notes
Differences in export turnover
Input tax credit mismatches

GST LUT and Refund of ITC

One important reason businesses choose the LUT route is the possibility of claiming a refund of eligible accumulated input tax credit relating to zero-rated supplies, subject to the applicable GST refund rules.

The refund calculation is governed by the prescribed formula and eligibility requirements. Therefore, having an LUT does not by itself guarantee a refund of every amount appearing in the electronic credit ledger.

Businesses should reconcile their input tax credit and export turnover before filing a refund application.

GST LUT vs Export With Payment of IGST

Particular	Export Under LUT	Export With IGST
IGST paid upfront	No, where eligible	Yes
LUT required	Yes	Generally not for this route
Working capital impact	May be lower because IGST is not paid upfront	IGST is paid before applicable refund
Refund route	Eligible accumulated ITC may be claimed subject to rules	Refund of tax paid may be available subject to applicable provisions
Export documentation	Required	Required

Example of GST LUT Compliance

Suppose an Indian company provides eligible software development services worth ₹10 lakh to an overseas customer.

If the transaction satisfies the conditions for export of services and the company has furnished a valid LUT, it may supply the services without payment of IGST, subject to the applicable provisions.

The company should then:

Issue the appropriate export invoice.
Include the prescribed LUT-related export endorsement where applicable.
Report the transaction correctly in GST returns.
Maintain evidence supporting the export.
Track receipt of payment within the applicable period.
Reconcile the transaction with accounting and banking records.
Claim eligible ITC refund according to the applicable refund provisions, if applicable.

Common Mistakes in GST LUT Filing

Filing the LUT after starting exports instead of planning it in advance
Selecting an incorrect financial year
Using outdated authorised signatory details
Ignoring DSC or EVC verification problems
Not saving the LUT acknowledgement
Failing to reconcile export invoices
Reporting incorrect export values in GST returns
Not maintaining export documentation
Ignoring payment-receipt requirements for export of services
Assuming that every foreign-currency transaction automatically qualifies as an export of services

GST LUT Verification Checklist

Before completing GST LUT verification, use the following checklist:

GSTIN is active
Legal name is correct
Authorised signatory details are updated
Correct financial year is selected
Export activity qualifies for the LUT route
Required undertaking details are correct
Witness information is entered where required
DSC/EVC authentication is working
LUT submission is successfully completed
Acknowledgement/reference is saved
Export invoices contain the applicable endorsement
Export transactions are correctly reported in GST returns
Supporting export documents are preserved

Does GST LUT Need Departmental Approval?

The LUT filing process is designed to be handled electronically through the GST system. However, taxpayers should distinguish between successful filing/acknowledgement and any separate departmental communication or verification that may arise in a particular case.

If the portal displays an issue, deficiency, rejection or other communication, the taxpayer should respond according to the applicable procedure.

Can GST LUT Be Filed Without Exports?

A business should furnish an LUT when it intends to use the LUT route for eligible zero-rated exports. Filing an LUT should therefore be connected with a genuine business requirement to make qualifying exports without payment of IGST.

Businesses should not treat LUT filing as a substitute for establishing that a transaction actually qualifies as an export under GST law.

What If LUT Was Not Filed Before Export?

Rule 96A contemplates furnishing the LUT before making the relevant export. However, CBIC has also issued guidance dealing with situations where exports were made before LUT filing and has indicated that, in appropriate circumstances, the substantive benefit of zero-rating should not necessarily be denied merely because of a procedural delay, subject to the applicable facts and legal requirements.

Because the consequences can depend on the facts, businesses facing this situation should review the applicable provisions and obtain professional advice rather than assuming that a delayed LUT is automatically acceptable.

GST LUT for Freelancers and Small Businesses

Freelancers and small businesses providing eligible services to overseas clients should pay particular attention to LUT compliance.

For example, an Indian freelancer providing software development, design or consulting services to an overseas business may need to examine whether the transaction satisfies all conditions for export of services.

The freelancer should maintain:

Client agreement
Invoices
GST records
Bank/payment records
Foreign remittance evidence where applicable
LUT acknowledgement
GST return records

Proper documentation can be particularly important for businesses that operate with a small accounting team.

GST LUT Verification and Business Compliance

LUT compliance should not be treated as an isolated annual task. Exporters should connect their LUT records with their accounting, GST return filing and refund processes.

A practical compliance cycle can be:

File the LUT for the relevant financial year.
Verify the acknowledgement.
Issue export invoices correctly.
Record export transactions in accounting software.
Reconcile GSTR-1 with books.
Reconcile GSTR-3B with books and GSTR-1.
Track export documentation.
Monitor receipt of export proceeds where applicable.
Reconcile input tax credit.
Prepare eligible refund claims where applicable.
