Indian GST treats exports and qualifying supplies to a Special Economic Zone (SEZ) developer or unit as zero-rated supplies. A registered supplier generally chooses between two refund routes: pay IGST and seek a refund of that IGST, or supply under a bond or Letter of Undertaking (LUT) without paying IGST and seek a refund of eligible unutilized input tax credit (ITC). The correct route depends on eligibility, cash flow, export or SEZ evidence, return reconciliation and current statutory restrictions.
What “zero-rated supply” means under GST
Under section 16(1) of the Integrated Goods and Services Tax Act, 2017, zero-rated supply covers:
As an Amazon Associate I earn from qualifying purchases.
- Export of goods or services, or both; and
- Supply of goods or services, or both, to an SEZ developer or an SEZ unit.
This is different from an exempt supply. A zero-rated supplier can generally seek a refund connected with the supply, subject to the conditions in the IGST Act, the Central Goods and Services Tax (CGST) Act, the refund rules and applicable notifications. The tax treatment is therefore not simply “no tax and no credit”; the business must select and complete a permitted refund route.

The two statutory options can be stated simply: a registered person making a zero-rated supply may supply without payment of IGST under bond or LUT and claim eligible unutilized ITC, or pay IGST on the supply and claim a refund of the IGST paid.
#1 Best Overall
The two GST refund routes
| Decision point | Pay IGST, then claim IGST refund | Supply under LUT or bond, then claim ITC refund |
|---|---|---|
| IGST on outward supply | Paid before or with the export/SEZ supply | Not paid on the zero-rated outward supply |
| What the refund represents | IGST charged and paid on the zero-rated supply | Eligible unutilized ITC accumulated in relation to permitted zero-rated supplies |
| Main export evidence | Shipping bill for exported goods, plus valid return and export-manifest/report data | Prescribed export or SEZ evidence, ITC records and the refund application |
| Typical electronic application | For exported goods, the shipping bill is treated as the refund application when statutory conditions are met | FORM GST RFD-01 through the GST common portal |
| Cash-flow effect | Cash is used to pay IGST and is recovered only after the refund process | No IGST cash outflow on the outward supply, but accumulated credit remains tied up until the ITC refund is sanctioned |
| Key restrictions | Current return, customs and notification conditions must be satisfied | Export-duty, drawback and other statutory restrictions can prevent or limit the refund |
Neither route is automatically better for every exporter. Compare the timing of input payments, available working capital, the amount of accumulated ITC, customs and return readiness, and any restriction attached to the goods or the chosen drawback treatment.
Route 1: pay IGST and claim a refund
How the route works for exported goods
When goods are exported on payment of IGST, the exporter reports the relevant transaction in the prescribed GST return and export documentation. CBIC’s exporter FAQ explains that the shipping bill is treated as the refund application if the exporter has filed the prescribed valid return and the conveyance operator has furnished the export manifest or export report. Customs then processes the refund claim using the return information and export data.
This does not mean every shipping bill produces an automatic payment. Data must match across the GST return, invoice, shipping bill and customs export-manifest or report records. Errors in the GST identification number, invoice number, taxable value, tax amount, shipping-bill details or export status can stop or delay processing. Check the current customs and GST portal workflow because labels, validations and transmission arrangements can change.

Conditions to check before relying on the shipping-bill process
- The exporter is registered and has filed the required return for the relevant period.
- The shipping bill contains the correct exporter and invoice information.
- The goods have actually been exported and the conveyance operator has filed the export manifest or report.
- The IGST amount reported in the return agrees with the export documentation.
- The transaction is not blocked by a current statutory exclusion, notification or data mismatch.
When this route may suit a business
Paying IGST can be useful where the exporter has sufficient working capital and wants to recover the tax specifically paid on the outward export. It may also avoid waiting for a large pool of accumulated ITC to become refundable. The trade-off is the temporary cash outflow and the need for clean customs-to-return reconciliation.
Route 2: export under LUT or bond and claim unutilized ITC
What is refunded
Under this route, the exporter or qualifying SEZ supplier makes the zero-rated supply without payment of IGST under a bond or LUT and applies for a refund of eligible unutilized ITC. The credit can arise from GST paid on inputs and input services, but the refundable amount is governed by the applicable formula, records and statutory conditions. Not every balance in the electronic credit ledger is necessarily refundable.
Core statutory restrictions
Section 54 of the CGST Act identifies zero-rated supplies made without payment of tax as a permitted refund category, but it also states important limits. A refund is not available where the exported goods are subject to export duty. The stated provision also restricts a claim where the supplier has availed drawback in respect of central tax or claimed a refund of IGST paid on those supplies. The exact interaction with current drawback schemes, notifications and later amendments must be checked for the period and goods concerned.
The applicant must provide prescribed evidence establishing that a refund is due. Where the law requires it, the applicant must also establish that the tax burden has not been passed on to another person. Maintain a clear link between purchase invoices, eligible ITC, outward export or SEZ invoices, returns and the refund computation.

When this route may suit a business
An LUT or bond route avoids paying IGST on each outward zero-rated invoice, which can protect working capital. It is often considered where input taxes accumulate consistently and the business can support a detailed ITC-based claim. The business must nevertheless carry the compliance burden of preserving credit records and proving the eligible refund amount.
How to file a general GST refund claim
The GST refund rules identify FORM GST RFD-01 as the electronic application through the common portal for general refund categories, including eligible unutilized ITC claims. The procedure and attachments vary by category; an exporter should not assume that one checklist applies to every claim.
- Identify the legal category. Confirm whether the claim concerns IGST paid on exports, unutilized ITC for zero-rated supplies without payment of tax, an SEZ supply or another refund category.
- Confirm the relevant period and limitation. Use the applicable statutory time limit and current rules for that type of claim. Keep the calculation period consistent with the returns and invoices used.
- Reconcile the outward supplies. Match export invoices with shipping bills, export reports or manifests, and the relevant GST return data. For services, retain evidence required to establish the export or authorized SEZ supply.
- Reconcile ITC. Tie the refund computation to purchase invoices, the electronic credit ledger, filed returns and the eligible-credit formula. Remove ineligible, blocked or otherwise excluded credit.
- Prepare category-specific evidence. Include the documents and declarations prescribed for the route. SEZ claims have their own endorsement and admission requirements.
- Submit RFD-01 where required. Upload the application and supporting records on the GST common portal, complete the declaration and retain the acknowledgement and reference number.
- Monitor notices and deficiencies. Respond within the time stated in any notice, correcting data or supplying evidence without changing the underlying facts improperly.
- Track sanction or rejection. Preserve the order, calculation and payment details. If the claim is rejected or reduced, review the stated reason and the available statutory remedy.
Special evidence for exports and SEZ supplies
Export of goods
For refunds involving exported goods, the rules link filing or processing to delivery of the export manifest or export report. Keep the commercial invoice, GST invoice, shipping bill, export order or transport records where relevant, return data and customs acknowledgement together. The shipping-bill route for IGST-paid exports is distinct from an RFD-01 claim for unutilized ITC.
Supply of goods to an SEZ
The refund rules refer to admission of the goods in full for authorized operations and endorsement by the specified officer. Retain the endorsed evidence and ensure the supply is genuinely for the SEZ’s authorized operations.

For SEZ services, the rules call for evidence of receipt for authorized operations endorsed by the specified officer. A tax invoice alone should not be treated as conclusive proof of the required SEZ receipt or authorized use.
Timelines: 60 days, 90% provisional refund and seven days
The statutory text provides that a complete refund application should be acted on within 60 days. It also describes a provisional refund of 90% for qualifying zero-rated claims, subject to exclusions and prescribed safeguards. CBIC’s exporter FAQ describes a provisional process within seven days of acknowledgement for eligible claims.
These figures are conditional process standards, not guaranteed payout dates for every exporter. The 60-day period concerns a complete application; missing evidence, a deficiency memo, reconciliation problems, investigation or an ineligible claim can affect the outcome. The 90% and seven-day provisions depend on the claimant, claim category and safeguards in force at the relevant time. Check current law, rules, notifications and portal instructions before forecasting cash receipts.
Common failure points and practical fixes
Return and shipping-bill mismatch
Symptom: a shipping bill exists but the refund is not processed. Fix: compare the GSTIN, invoice number, invoice date, taxable value and IGST amount in the return and customs records; correct permitted return errors and confirm that the export manifest or report was filed.
Export manifest or report not available
Symptom: customs has no completed export status. Fix: obtain confirmation from the carrier or customs intermediary that the conveyance operator filed the manifest or report and that the shipment was marked as exported.
Using the wrong refund route
Symptom: the application requests an ITC refund even though IGST was paid on the same outward supplies, or claims IGST after using a no-tax LUT route. Fix: separate tax-paid supplies from LUT or bond supplies in the accounting and refund computation.
Ineligible or unsupported ITC
Symptom: the claimed amount exceeds the eligible credit supported by invoices and returns. Fix: reconcile the electronic credit ledger, remove blocked or unsupported credits, and retain a calculation that can be followed from source invoice to claim.
Drawback or export-duty restriction
Symptom: the claim concerns goods subject to export duty or a drawback/IGST combination restricted by section 54 or current notifications. Fix: check the treatment applicable to the exact goods, period and scheme before filing; do not assume a restriction described in older guidance is unchanged.
SEZ endorsement missing
Symptom: the supply is reported as an SEZ transaction but lacks the required authorized-operations admission or receipt endorsement. Fix: obtain the prescribed endorsement from the specified officer and keep it with the invoice and refund records.
Best Value
A decision framework for choosing the route
- Choose the IGST-paid route for consideration when the business can fund the tax outflow, the export data is reliably reconciled and recovering the exact IGST paid is operationally preferable.
- Choose the LUT or bond route for consideration when avoiding outward IGST improves cash flow and the business has substantial, traceable eligible ITC for a compliant refund claim.
- Pause and verify when drawback, export duty, mixed supplies, amended invoices, SEZ documentation or old refund restrictions are involved.
- Model timing, not only amount. A larger theoretical refund may be less useful if records are incomplete or the credit remains blocked for months; a tax-paid route may be costly if working capital is tight.
The law establishes the available routes, but it does not establish one universally financially preferable option. Use the taxpayer’s actual margins, credit balance, shipment cycle and compliance capacity.
Records to retain
- GST registration and LUT or bond records, where applicable;
- GST invoices, commercial invoices and export contracts;
- Shipping bills, bills of lading or airway bills and export-manifest/report evidence;
- SEZ specified-officer endorsements for authorized operations;
- Filed GST returns and electronic credit-ledger extracts;
- Input-tax invoices and the ITC eligibility reconciliation;
- Refund calculations, declarations, acknowledgements and portal correspondence;
- Customs, carrier and bank records that support the export transaction and receipt where relevant.
Keep records in a form that lets an officer trace each claimed amount from the outward supply to the return, customs or SEZ evidence and the underlying credit.
What to verify before filing
GST refund law and portal procedures are amended periodically. Before submitting a claim, verify the current version of section 16 of the IGST Act, section 54 of the CGST Act, the refund rules, relevant notifications and customs instructions. Historical clarifications, including CBIC Circular No. 125/44/2019-GST dated 18 November 2019, should not be treated as a complete statement of current restrictions without checking later amendments.

Bottom line
GST refunds for Indian exporters are built around a choice: pay IGST and seek that tax back, or export and make qualifying SEZ supplies under LUT or bond and seek eligible unutilized ITC. The route, evidence and restrictions differ. Accurate returns, matching shipping or SEZ records, defensible ITC calculations and current-law checks are what turn a zero-rated transaction into a successful refund claim.
