Introduction: Why Exports Under GST Matter

Exports are a crucial pillar of India’s economy, and under the GST regime, they receive preferential treatment as zero-rated supplies. This ensures that Indian exporters remain globally competitive by allowing Input Tax Credit (ITC) refunds on inputs used for exports, even when no GST is charged on the export itself.

Understanding exports under GST in India is vital for businesses aiming to manage cash flows, avoid refund delays, and remain compliant while maximizing tax benefits. This 2025 guide breaks down export treatment under GST, compliance procedures, documentation, refund mechanisms, and best practices to safeguard your claims and avoid pitfalls.

Exports are Zero-Rated Under GST

Exports, defined as the supply of goods or services from India to a place outside India, are treated as zero-rated supplies under Section 16 of the IGST Act. This means:

✅ No GST is charged on the export invoice.
✅ Input Tax Credit (ITC) on inputs/services used for exports is fully claimable.
✅ Exporters can claim a refund of unutilized ITC or claim a refund of IGST paid on exports.

This treatment ensures that GST does not add to the cost of exported goods or services, maintaining global competitiveness for Indian exporters.

Export Modes and Compliance Options

Exporters can choose between two methods for GST compliance:

1️⃣ Export Under Bond or LUT (Without Payment of IGST)

• No IGST is charged on exports.
• Exporters must furnish a Letter of Undertaking (LUT) or a bond on the GST portal.
• Refund of unutilized ITC on inputs/services can be claimed.

Best for liquidity management as no upfront tax is paid.

2️⃣ Export on Payment of IGST and Claim Refund

• IGST is paid on the export invoice at applicable rates.
• A refund of the IGST paid can be claimed post-export and customs clearance.
• Refunds are typically faster but require upfront tax payment.

Suitable for businesses with ample working capital or needing quicker refunds.

Essential Compliance for GST Exports

To qualify exports as zero-rated:

✅ The place of supply must be outside India.
✅ The transaction must be treated as an export under Section 2(5) of IGST Act.
✅ Goods must physically leave India; services must meet export conditions under GST.
✅ Correct HSN codes and SAC codes must be used for GST and customs reconciliation.

Refund Process and Required Paperwork

To claim GST refunds on exports:

✅ File export invoices accurately on the GST portal.
✅ Submit LUT on the GST portal annually for exports without IGST payment.
✅ File GSTR-1 (reporting exports) and GSTR-3B (summary returns) consistently.
✅ Maintain shipping bills, export invoices, EGM (Export General Manifest), and proof of export.
✅ Use Form RFD-01A to claim refund of unutilized ITC, if applicable.

Timely filing and clean documentation ensure faster refunds and reduce audit risks.

Customs Interface for Exporters

Pre-Shipment Requirements

✅ Obtain Import Export Code (IEC).
✅ File a shipping bill through ICEGATE/customs, detailing the export consignment.
✅ Engage a Customs House Agent (CHA) for efficient clearances.
✅ Ensure HSN codes match GST filings and customs declarations.

Post-Shipment Process

✅ Let Export Order (LEO) issued by customs, marking the shipment as exported.
✅ Risk-based checks under customs may apply.
✅ Maintain export-related documentation for potential audit follow-ups.

Best Practices and Pitfalls to Avoid

✅ Use correct HSN codes on export invoices for GST and customs alignment.
✅ Maintain detailed LUT records and proofs of export for compliance and refund validation.
✅ Reconcile GST returns with export documentation regularly.
✅ File returns on time; delays can impact refund processing.
✅ Keep audit trails and export-related records for 72 months as required under GST law.
✅ Monitor GST notifications for changes in export refund rules or rates.

Common Pitfalls:

❌ Missing LUT renewal annually, leading to unnecessary IGST payment.
❌ Incorrect invoice data causing refund rejections.
❌ Non-reconciliation between shipping bills and GST returns.
