💡 Key Takeaways: Export Refund GST
- Exports of goods and services qualify as zero rated supplies under Section 16 of the IGST Act, meaning no tax burden is passed to foreign buyers.
- Exporters can claim an export refund gst through two distinct routes: Exporting under LUT GST (claiming unutilized ITC) or Exporting on payment of IGST (claiming tax refund).
- When exporting under LUT without payment of IGST, refund of unutilized Input Tax Credit (ITC) is calculated using the statutory formula under Rule 89(4) of CGST Rules.
- Filing a valid Letter of Undertaking (Form GST RFD-11) prior to exporting is mandatory to claim refund without paying upfront integrated tax.
- Provisional refund equal to 90% of the eligible claim is granted within 7 days of receiving Form RFD-02 acknowledgment for LUT exports.
Exporting goods and services from India is a cornerstone of economic growth, and the GST framework is specifically structured to ensure Indian exports remain globally competitive. Under GST law, exports are classified as zero rated supplies. This fundamental principle ensures that taxes paid on input materials or services do not become a cost burden for foreign trade.
However, many businesses struggle with selecting the right refund mechanism or navigating the mathematical adjustments required for an export refund gst claim. This guide breaks down the legal pathways, Rule 89(4) calculations, and the online procedure to claim your unutilized Input Tax Credit (ITC) seamlessly on the GST Common Portal.
Two Options for Claiming GST Refund on Exports
Section 16(3) of the IGST Act provides exporters with two distinct mechanisms to claim tax benefits on zero-rated exports:
| Feature | Option 1: Export under LUT/Bond | Option 2: Export on Payment of IGST |
|---|---|---|
| Upfront Tax Outflow | Zero (No tax paid on export invoice) | High (IGST paid using cash/credit) |
| Prerequisite Document | Filing Form GST RFD-11 (LUT GST) | Direct IGST Payment entry in GSTR-3B & GSTR-1 |
| Type of Refund Claimed | Refund of Unutilized Input Tax Credit (ITC) | Refund of Integrated Tax (IGST) paid |
| Filing & Processing Route | File Form GST RFD-01 on portal with Statement 3/3A | Automated processing via Customs ICEGATE system |
| Eligible Credit Scope | Inputs & Input Services (Capital Goods excluded) | Full IGST amount paid on export invoice |
Rule 89(4) Formula for Refund of Unutilized ITC
When you export goods or services without payment of tax under a Letter of Undertaking, your accumulated credit ledger holds unutilized ITC from domestic purchases. To claim this refund under Section 54(3), the portal applies the statutory mathematical formula prescribed under Rule 89(4) of the CGST Rules:
Where key variables are defined as follows:
- Turnover of Zero-Rated Supplies: Total value of zero-rated export supplies of goods and services made during the relevant period under LUT/Bond without payment of tax.
- Net ITC: Total input tax credit availed on inputs and input services during the tax period (excluding capital goods credit and ITC claimed under other specific refund sections).
- Adjusted Total Turnover: Sum of total turnover in the state/UT, excluding exempt supplies and non-zero-rated turnover.
Step-by-Step Procedure to Claim Export ITC Refund
Follow these steps on the GST Services Portal to file your application for unutilized credit refund:
1. Ensure Online Filing of Form GST RFD-11 (LUT)
Before executing any zero-rated exports without paying tax, navigate to Services → User Services → Furnish Letter of Undertaking (LUT). Complete Form RFD-11 for the current financial year. An ARN will be generated immediately.
2. File GSTR-1 & GSTR-3B Returns
Report all export invoices in Table 6A of Form GSTR-1 with “Export under LUT/Bond”. Ensure that shipping bill numbers, port codes, and invoice dates are entered accurately. File your corresponding GSTR-3B return for the period.
3. Prepare Offline Statement 3 / 3A Excel File
Download the Offline Tool for Refund on Exports. Enter invoice-wise shipping bill details, BRC/FIRC numbers (for export of services), FOB values, and taxable values. Validate and generate the JSON file.
4. Initiate Form GST RFD-01 Application
Log in to the GST portal, go to Services → Refunds → Application for Refund. Select “Refund of unutilized ITC on account of exports without payment of tax” and select the tax period. Upload the JSON file and auto-populate Net ITC and turnover details.
5. Verification, CA Certificate & DSC Submission
Verify bank details. If the claim exceeds ₹2 Lakhs, attach a Chartered Accountant certificate in Annexure 2 disproving unjust enrichment. Submit using Digital Signature Certificate (DSC) or EVC.
