LUT for Exporters: Annual Renewal, Invoice Checks and Refund Documentation

Introduction

Businesses exporting goods or services need to manage GST documentation carefully. Along with commercial invoices, shipping records, payment evidence and accounting entries, exporters must determine how their supplies will be treated under the GST framework.

A Letter of Undertaking, commonly known as an LUT, allows eligible registered taxpayers to export goods or services without paying Integrated Goods and Services Tax (IGST) at the time of making the supply, subject to the applicable conditions. This option can help businesses avoid paying IGST upfront on qualifying exports while maintaining eligibility to claim a refund of eligible unutilised input tax credit, subject to the law.

However, filing the LUT is only one part of export compliance. Businesses also need to monitor its validity, prepare export invoices correctly, preserve evidence of actual exports, track payment receipts and reconcile their GST returns with refund calculations.

A structured process helps exporters identify missing documents early and reduces avoidable delays when preparing refund applications.

What Is an LUT Under GST?

An LUT is a Letter of Undertaking furnished in Form GST RFD-11 under Rule 96A of the Central Goods and Services Tax Rules, 2017. It is used by eligible registered persons who intend to make qualifying exports without payment of IGST.

Exports are treated as zero-rated supplies under the GST framework, subject to the applicable provisions. Eligible exporters generally have the option to supply under an LUT without payment of IGST and seek a refund of eligible accumulated input tax credit, subject to the statutory conditions and restrictions.

The LUT is not a general exemption from GST compliance. Exporters must continue to maintain proper records, issue appropriate invoices, report transactions correctly and comply with the conditions applicable to export supplies.

The relevant legal provisions are available through Rule 96A of the CGST Rules and the CBIC GST guidance on exports.

Who Should Consider Filing an LUT?

An LUT may be relevant to a GST-registered business that intends to make eligible export supplies without payment of IGST. This can include manufacturers exporting products, merchant exporters, service providers serving overseas clients and businesses supplying qualifying goods or services to recipients outside India.

Before filing, the business should confirm that it meets the applicable eligibility conditions. The facility is subject to restrictions under the relevant notifications and rules, including specified circumstances involving prosecution for tax evasion.

Exporters should also distinguish between an export of goods, an export of services and other cross-border transactions. A transaction does not automatically qualify as an export merely because the customer is located outside India. The relevant statutory conditions must be satisfied.

1. Understand the Annual Validity of an LUT

An LUT is generally valid for the financial year in which it is furnished. Filing an LUT in one financial year does not automatically extend its validity to the following year.

For example, an LUT furnished for FY 2026–27 generally covers the applicable period within that financial year. An exporter intending to continue making eligible exports under LUT in FY 2027–28 should complete the filing process for the new financial year.

Businesses should not wait until an export order is ready for dispatch to check the LUT status. The finance or compliance team should include LUT renewal in its annual GST calendar and confirm that the new filing is completed before making supplies under the intended arrangement.

2. How to File an LUT on the GST Portal ?

The LUT is furnished online through the GST Portal in Form GST RFD-11. The exporter should use the appropriate GST registration credentials and select the financial year for which the application is being made.

The usual process involves the following steps:

1. Log in to the GST Portal using the registered taxpayer credentials.

2. Navigate to Services, then User Services, and select Furnish Letter of Undertaking (LUT).

3. Select the relevant financial year.

4. Complete the required declarations and other fields displayed in the form.

5. Upload the previous LUT if requested by the portal.

6. Provide the required witness details where applicable in the online form.

7. Submit the application using the permitted verification method.

8. Download and preserve the acknowledgement and ARN generated by the portal.

The exact fields and screen sequence may change as the GST Portal is updated. Follow the current instructions displayed during filing.

According to the GST Portal's official Furnishing of Letter of Undertaking user manual, the process is performed through the online Form GST RFD-11 workflow. An online acknowledgement should be retained as evidence of filing.

3. Review Export Invoices Before Issuing Them

An export invoice should accurately describe the transaction and contain the particulars required under the applicable GST invoice rules. The invoice should also reflect the correct export treatment.

For supplies made under an LUT without payment of IGST, the invoice should carry the prescribed endorsement indicating that the supply is meant for export under bond or Letter of Undertaking without payment of integrated tax.

The exporter should check the following details before issuing the invoice:

For export of goods, invoice details should be capable of being reconciled with shipping documents and customs export records. For export of services, the invoice should be supported by the service agreement, scope of work, delivery evidence and payment records, as applicable.

A mismatch in the invoice date, invoice number, recipient details or taxable value can complicate reconciliation later. These details should be checked before the invoice is finalised rather than corrected only when a refund application is prepared.

4. Maintain the Right Documents for Export of Goods

Exporters of physical goods need a document trail connecting the sale, dispatch, customs clearance and accounting records. The exact documents depend on the nature of the goods, the shipping arrangement and the export transaction.

A typical document checklist includes:

• Export tax invoice containing the required particulars and endorsement.

• Purchase order, sales contract or customer order confirmation.

• Packing list, where applicable.

• Shipping bill and relevant customs export records.

• Bill of lading, airway bill or other transport documentation.

• Export general manifest or other relevant evidence of export, where applicable.

• Foreign remittance and bank realisation records, where available and relevant.

• Credit notes, debit notes and records of cancelled or amended transactions.

• Sales register and corresponding accounting entries.

• GST returns and refund working papers.

The purpose of retaining these documents is to demonstrate that the transaction was recorded consistently from the original order through the actual export and subsequent settlement.

For refund claims involving export of goods, ensure that the export and tax reporting information can be reconciled with the applicable customs and GST records.

5. Maintain Supporting Evidence for Export of Services

Export of services requires a different supporting-document approach because the supply may not involve physical movement of goods through customs.

A service provider should preserve records that demonstrate the nature of the service, the overseas recipient, the contractual relationship, the delivery of the service and the consideration received or receivable.

Depending on the transaction, supporting documents may include:

• Signed service agreement, statement of work or purchase order.

• Export invoice and invoice-level accounting entries.

• Project reports, deliverables, email approvals or service acceptance records.

• Correspondence identifying the recipient and the services supplied.

• Bank statements and inward remittance advice.

• Foreign inward remittance certificate or other bank documentation, where available and relevant.

• Applicable payment-platform statements for overseas collections.

• GST returns and refund calculations.

• Records supporting the determination that the supply qualifies as an export of services.

The exporter should assess the statutory definition of export of services, including the conditions relating to the supplier, recipient, place of supply, permitted consideration and establishment of the parties. Receiving money from a foreign customer alone does not establish that every transaction qualifies as an export of services.

6. Monitor the Conditions Under Rule 96A

Filing an LUT creates an undertaking to comply with the conditions applicable to exports made without payment of IGST. Exporters should monitor the prescribed timelines and investigate transactions that remain incomplete.

Rule 96A contains conditions relating to export of goods and receipt of payment for export of services. Broadly, where goods are not exported within three months from the date of the export invoice, or payment for exported services is not received within one year from the invoice date in the circumstances covered by the rule, the exporter may become liable to pay the applicable tax with interest within the prescribed period, unless a permitted extension or other applicable relief is available.

The rule also contains provisions regarding extensions and restoration of the facility in specified circumstances. The precise treatment depends on the facts and applicable legal provisions.

The compliance team should therefore maintain a pending-export tracker rather than relying only on completed invoice records.

Do not assume that every delayed shipment or delayed payment automatically results in the same tax outcome. Review the relevant facts, available extensions and applicable CBIC clarifications before deciding the treatment.

7. Prepare Documents for Refund of Unutilised Input Tax Credit

An exporter supplying under LUT without payment of IGST may be eligible to claim a refund of unutilised input tax credit, subject to the conditions, restrictions and calculation methodology prescribed under the GST law.

A refund application should be supported by a consistent set of records. The exact documents depend on the type of refund, the nature of the exports and the applicable portal requirements.

Before preparing the claim, review:

For export of goods, refund-related details may need to be reconciled with shipping bills and customs records. For export of services, invoice details, eligible turnover, payment evidence and the prescribed documentation should be reviewed carefully.

The exporter should also verify whether the refund route being used is appropriate for the transaction. A refund of unutilised ITC under an LUT is different from a claim for refund of IGST paid on exports.

8. Reconcile GST Returns With Export Records

Export transactions should be recorded consistently across the sales register, GST returns, accounting system and refund workings.

Before filing returns or submitting a refund claim, compare the invoice-level data with the reported outward supplies. Identify differences caused by amendments, credit notes, cancelled invoices, changes in export values or missing supporting records.

A monthly reconciliation should answer the following questions:

• Have all reportable export invoices been recorded in the correct period?

• Are invoice numbers, dates and taxable values consistent across the books and returns?

• Have amendments and credit notes been reflected appropriately?

• Do export turnover figures agree with the supporting sales and export records?

• Is the input tax credit included in the refund calculation eligible and supported?

• Are any invoices awaiting export, payment or documentation?

• Have previous refund deficiencies or outstanding queries been resolved?

A documented reconciliation helps the business identify problems before the refund application is submitted. It also provides a clear record for internal review and any subsequent departmental query.

9. Common LUT and Export Documentation Mistakes

One common error is assuming that an LUT automatically continues into the next financial year. Since the LUT is generally valid for the financial year in which it is furnished, exporters should schedule a fresh filing for the next year.

Another problem is issuing export invoices without the prescribed endorsement or retaining invoices without the supporting commercial documents. This can make it harder to establish the connection between the supply, export and accounting entries.

Businesses may also overlook pending service payments, incomplete shipping records, mismatches between invoice values and customs records, or differences between GST returns and refund workings.

Refund applications can become difficult to support when the business calculates eligible ITC without first checking the underlying purchase records and applicable restrictions. Similarly, an exporter should not assume that every input tax credit appearing in its records can automatically be included in a refund claim.

The best approach is to maintain a standard checklist, assign responsibility for each document and close discrepancies before filing.

10. Annual LUT and Monthly Export Compliance Checklist

Exporters can separate annual LUT filing from recurring transaction checks to avoid missing important requirements.

The checklist should be adapted to the business's export model. A goods exporter may need more detailed shipping and customs tracking, while a service exporter may need a stronger system for contract records, delivery evidence and payment monitoring.
