GST Refund Problems Faced by Exporters

GST Refund Problems Faced by Exporters in India – Causes and Solutions 2026

Table of Contents:-

GST refund problems faced by exporters in India commonly arise because of mismatches between GST returns and Customs records, incorrect shipping bill details, missing Export General Manifests, incomplete documentation, ineligible input tax credit and errors in refund applications.

Exporters of goods and services may be eligible for GST refunds under the zero-rated supply provisions of the Integrated Goods and Services Tax Act, 2017, read with Section 54 of the Central Goods and Services Tax Act, 2017 and the applicable GST Rules.

However, refund processing depends on the chosen export mechanism, return filing, documentation, electronic validation and satisfaction of the applicable statutory conditions.

October 2026 update: CBIC Circular No. 263/09/2026-GST dated 26 October 2026 clarifies important matters relating to receipt of export proceeds in qualifying repatriable INR accounts, permitted set-offs and recovery of export refunds where foreign-exchange realisation requirements are written off by authorised dealer banks. Circular No. 264/10/2026-GST also addresses the treatment of certain earlier refund restrictions.

This guide explains why IGST refunds get blocked, how exporters can correct ICEGATE errors, the difference between refunds under LUT and with payment of IGST, and how to prepare a defensible refund application.

EzyBiz India Consulting LLP assists exporters with GST refund claims, invoice reconciliation, RFD-01 preparation, departmental queries, refund rejection and related GST compliance.

GST Refund Problems Faced by Exporters – Overview

Why Do Exporters Face GST Refund Delays?

GST export refunds require matching of invoices, GST returns, Customs information and, where applicable, evidence of foreign-exchange realisation.

Errors in one or more of these records may prevent electronic validation or result in departmental scrutiny.

Types of GST Refund Available to Exporters

Exporters may claim refunds through different routes, including refund of IGST paid on eligible exports or refund of accumulated input tax credit on zero-rated supplies made without payment of IGST.

The correct procedure depends on the type of supply, legal eligibility and option exercised by the exporter.

Difference between Goods and Services Refunds

Export-of-goods refunds often involve Customs and ICEGATE validation. Export-of-services refunds depend on applicable RFD-01 procedures and evidence supporting the statutory export-of-services conditions.

Exporters should not assume that the shipping-bill refund process applies equally to every export of services.

GST Refund on Exports with Payment of IGST

Shipping Bill as a Deemed Refund Application

Under Rule 96 of the CGST Rules, the shipping bill is generally treated as the refund application for eligible IGST paid on exported goods, once the prescribed conditions are satisfied.

This mechanism does not ordinarily require a separate RFD-01 application for the original IGST amount paid on exported goods.

GSTR-1 and GSTR-3B Requirements

The exporter should correctly report export invoices in Table 6A of GSTR-1 and the relevant zero-rated supply information in GSTR-3B.

Data must pass the relevant validations for transmission to Customs and subsequent refund processing.

Role of ICEGATE and Customs

ICEGATE validates GST data against shipping bills, export manifests and other relevant Customs records.

When the prescribed checks are completed, the refund can proceed through the Customs refund system, subject to any applicable withholding or verification.

See the official ICEGATE FAQs for export refund validation requirements.

GST Refund under LUT without Payment of IGST

What Is a Letter of Undertaking?

An eligible exporter may furnish a Letter of Undertaking (LUT) and undertake zero-rated supplies without payment of integrated tax, subject to the applicable conditions.

This route can reduce upfront tax-related working-capital requirements.

Refund of Accumulated Input Tax Credit

Eligible exporters making zero-rated supplies without payment of IGST may claim refund of accumulated ITC under Section 54(3) and Rule 89.

The refund must be determined using the applicable statutory formula and eligible input tax credit.

RFD-01 Filing and Refund Period

The refund application is generally filed electronically in FORM GST RFD-01 with prescribed statements, declarations and supporting evidence.

The exporter should verify the relevant refund period, applicable limitation and return-filing requirements before filing.

For application assistance, see our GST Refund Services.

Mismatch between GSTR-1 and Shipping Bill

Incorrect Shipping Bill Number or Date

A mismatch between shipping bill particulars in GST returns and Customs data can prevent validation of an IGST refund claim.

Exporters should compare the exact shipping bill number, date and port code against the GST return records.

Incorrect Invoice Number or GSTIN

Differences in invoice numbers or GSTIN details may result in an ICEGATE validation error.

The tax invoice declared in the GST return should be appropriately reconciled with the export invoice details in Customs records.

Correcting Export Information through GSTR-1

Where legally permissible, exporters can use the relevant amendment facility, including Table 9A of GSTR-1, to correct export invoice and shipping bill particulars.

The appropriate amendment depends on the nature of the error and the statutory time limits.

ICEGATE IGST Refund Error Codes and Solutions

SB001, SB003 and SB005 Errors

These errors commonly relate to invalid shipping bill details, GSTIN mismatches or invalid invoice numbers.

The exporter should reconcile GST return data and Customs records and use the appropriate correction mechanism.

SB002 and SB006 EGM Errors

SB002 generally indicates that the required export manifest has not been filed. SB006 generally relates to the absence of a gateway EGM.

Exporters may need to coordinate with the shipping line, airline, carrier or relevant Customs authority to resolve these issues.

SB004 and Other Validation Statuses

SB004 ordinarily indicates that the relevant record has already been received and validated, rather than necessarily representing a new substantive mismatch.

The exporter should review the complete validation status and refund scroll before concluding that the refund has failed.

ICEGATE Code Indicative Meaning Action
SB000 Successfully validated Track refund scroll and payment
SB001 Invalid shipping bill details Reconcile shipping bill number, date and port
SB002 EGM not filed Contact carrier or shipping line
SB003 GSTIN mismatch Reconcile GSTIN across records
SB004 Record already received Check previous validation and scroll
SB005 Invalid invoice number Correct invoice mismatch where permitted
SB006 Gateway EGM unavailable Coordinate gateway EGM correction

Refer to the ICEGATE official troubleshooting FAQs for individual error-code guidance.

Missing EGM and Customs Export Confirmation

What Is an Export General Manifest?

An Export General Manifest or corresponding export report is filed by the responsible carrier or conveyance operator under Customs procedures.

It supports confirmation that the relevant goods were exported.

What Happens When EGM Is Not Filed?

The IGST refund may remain pending because the prescribed Customs validation is incomplete.

Filing GST returns alone does not resolve an outstanding EGM requirement.

How to Correct Gateway EGM Issues

Exporters using Inland Container Depots should verify whether the gateway EGM has been filed and correctly linked to the shipping bill.

Where necessary, coordinate the correction through the shipping line, carrier and Customs authorities.

GSTR-1 and GSTR-3B Mismatch in Export Refund

Mismatch in Export Turnover

Refund processing may be affected where export turnover disclosed in GSTR-1 and GSTR-3B does not reconcile.

Exporters should review taxable values, amendments, relevant periods and the reporting method applied.

Incorrect IGST Amount

Where the IGST amount reported in GST returns does not align with the export claim, the electronic validation or refund computation may be affected.

Review the payment records, export invoices and applicable return tables.

GSTR-1A and Amended Export Details

Rule 96 recognises amendments made in GSTR-1A, where applicable, in the process of matching export information.

Exporters should assess the relevant period and the legally available correction route before making changes.

Speak With Our Tax Experts

Documents for Export of Goods

Depending on the refund category, documentation may include export invoices, shipping bills, EGM records, GST returns, LUT, prescribed statements and tax payment evidence.

Additional records may be necessary where invoices have been amended or Customs discrepancies exist.

Documents for Export of Services

Relevant records may include service agreements, invoices, GST returns, FIRC/BRC or other permitted evidence of receipt, and prescribed refund statements.

The exact documents depend on the nature of the services and applicable export-of-services requirements.

How to Upload Supporting Documents

Arrange documents in a clear and consistent order and ensure they match the refund computation.

Check the GST Portal’s current attachment and file-size requirements before submitting RFD-01.

Read our Tips for Uploading Documents at the Time of GST Refund.

Foreign Remittance and FIRC/BRC Problems for Exporters

Receipt of Export-of-Services Consideration

The definition of export of services under Section 2(6) of the IGST Act includes a condition relating to receipt of payment in convertible foreign exchange or in Indian rupees where permitted by RBI.

Exporters should maintain reliable evidence of the relevant payment and its connection with the invoice.

Payments through SNRR and INR Nostro Accounts

CBIC Circular No. 263/09/2026-GST dated 26 October 2026 clarifies that qualifying receipts through repatriable INR accounts, including SNRR and INR Nostro arrangements, may satisfy the payment condition for export of services.

The actual transaction and banking arrangements must comply with applicable FEMA and RBI requirements.

Set-Off of Export Receivables and Import Payables

The same circular addresses RBI-permitted set-off arrangements for export receivables against import payables.

Exporters should retain the underlying contracts, invoices, bank records and relevant documentation supporting the permitted settlement.

Refer to CBIC Tax Information Portal – Circular No. 263/09/2026-GST for the official clarification.

Rule 96B and Non-Realisation of Export Proceeds

When Can Export Refund Be Recovered?

Rule 96B addresses recovery of refunds relating to export of goods where sale proceeds are not realised within the applicable FEMA period, including extensions.

The amount and consequences depend on the statutory conditions and actual extent of non-realisation.

RBI Time Limits and Authorised Dealer Banks

Circular No. 263/09/2026-GST clarifies that the applicable export-realisation period is determined by the relevant RBI framework, including extensions where permitted.

Exporters should obtain appropriate banking records demonstrating receipt, extension or any valid write-off.

Effect of Approved Write-Offs

The October 2026 circular clarifies that where the requirement of realisation has been written off by the authorised dealer bank under the relevant framework, recovery under Rule 96B should not be pursued on that ground.

This does not automatically dispense with other GST compliance or documentary requirements.

Refund Rejection Due to Ineligible Input Tax Credit

GSTR-2B and Purchase Register Mismatch

Refund claims may be scrutinised where purchase records and GSTR-2B contain differences.

Exporters should identify supplier reporting issues, ineligible credits and the statutory conditions for availing ITC.

Blocked Credit and Capital Goods

Input tax credit restricted under Section 17(5) must be excluded where applicable.

The Net ITC definition used in the standard Rule 89 export refund formula generally covers inputs and input services, not capital goods.

Refund Formula and Turnover Calculation

Calculate the eligible refund using the applicable Rule 89 formula and prescribed adjustments.

Export turnover, adjusted total turnover, relevant tax period and eligible ITC must be reconciled with the returns and books.

Refund Rejection, Deficiency Memo and Appeal

Deficiency Memo in FORM GST RFD-03

Where prescribed deficiencies are identified, the officer may issue FORM GST RFD-03.

The exporter should review the defects and determine the appropriate filing response under the applicable procedure.

Show Cause Notice in FORM GST RFD-08

Where refund rejection is proposed, the officer may issue RFD-08 and provide an opportunity to respond using RFD-09.

Prepare a point-wise response supported by the export documents and relevant legal provisions.

Appeal against Refund Rejection

Where an adverse appealable refund order is issued, the exporter should examine available remedies under Section 107 and the applicable limitation provisions.

The exporter should also consider relevant ITC re-credit requirements and avoid pursuing inconsistent remedies.

GST Export Refund Reforms and Circulars in October 2026

Circular 263/09/2026-GST – Export Proceeds

Circular No. 263/09/2026-GST provides guidance concerning export payment arrangements, permitted INR receipts and the impact of valid bank write-offs on Rule 96B recovery.

Businesses with outstanding export receivables should examine whether this clarification affects their particular refund position.

Circular 264/10/2026-GST – Earlier Refund Restrictions

CBIC Circular No. 264/10/2026-GST addresses the effect of the omission of Rule 96(10) and specified corresponding restrictions under Rules 89(4A) and 89(4B), following the Supreme Court’s decision in Goodluck India.

Exporters with historical disputes involving these provisions should review the circular, the judgment and the procedural status of their cases before seeking relief.

Importance of Current Rules over Outdated Guides

GST refund law and Customs processing procedures have undergone several changes since the introduction of GST.

Exporters should use the version of the statute, rules, circulars and portal instructions applicable to the relevant transaction and claim.

Practical Examples of GST Export Refund Delays

Example 1 – Incorrect Shipping Bill Number

Suppose a manufacturer declares a shipping bill number incorrectly in GSTR-1.

The Customs system may fail to validate the relevant invoice. The exporter should reconcile the source documents and correct the GST reporting through the permitted amendment procedure.

Example 2 – EGM Not Filed by Carrier

Suppose export invoices and tax payments are correctly reported but the responsible carrier has not filed the required EGM.

The exporter should coordinate with the carrier and Customs authorities because filing the GST return alone will not cure this defect.

Example 3 – Export Service Payment through INR Account

Suppose an Indian IT services exporter receives payment from a foreign client through a qualifying repatriable INR banking arrangement.

The exporter should review Circular No. 263/09/2026-GST, relevant RBI requirements and banking evidence before determining whether the payment condition for export of services is satisfied.

GST Refund Reconciliation and Internal Controls

Monthly Export Refund Reconciliation

Prepare a monthly reconciliation linking export invoices, GSTR-1, GSTR-3B, shipping bills, EGM status, foreign remittances and refund claims.

Separate claims under LUT from refunds of IGST paid to avoid confusion.

Maintain an ICEGATE Error Tracker

For goods exports, maintain a shipping-bill-wise tracker showing validation codes, mismatch reasons, correction dates and payment status.

Document communication with GSTN, Customs and carriers where relevant.

Maintain a Complete GST Refund Audit Trail

Keep tax invoices, books of account, return acknowledgements, refund workings, Customs documents, banking evidence and departmental correspondence.

Our Accounting and Bookkeeping Services can support ongoing reconciliation and record-keeping.
