An exporter that supplies goods or services without paying IGST under a valid bond or Letter of Undertaking (LUT) may seek a refund of eligible unutilized ITC under the CGST Act and refund rules. Zero-rating does not make every GST-bearing expense creditable, and the refund is limited by a statutory formula rather than the entire electronic credit-ledger balance.
What zero-rating means for an exporter
Under India’s GST framework, exports of goods and exports of services that satisfy the statutory conditions are zero-rated supplies. Zero-rating affects the output tax treatment, but it does not remove the ordinary conditions for taking ITC. The Integrated Goods and Services Tax Act, 2017, section 16(2), states that “credit of input tax may be availed for making zero-rated supplies.” The same provision makes that right subject to the blocked-credit rules in section 17(5) of the Central Goods and Services Tax Act.

In practical terms, a registered exporter can generally use eligible GST charged on purchases and business services connected with its export activity. If those credits accumulate because the exports carry no output tax, the exporter may be able to recover the eligible unutilized amount through the refund process. Eligibility still depends on the transaction, the invoice, the accounting and return records, and the statutory exclusions applicable to the claim period.

Which GST credits can qualify?
Inputs used in the export business
Inputs are goods used or intended for use in the course or furtherance of business. Depending on the exporter’s activity, this can include raw materials, components, packing materials, consumables and other goods that are actually used to make, process, pack or otherwise supply the exported product. The goods must be connected with the registered business and supported by a valid GST tax document and the required return reporting.
#1 Best Overall
A purchase does not become eligible merely because the eventual sale is an export. The business should be able to show the connection between the input and the taxable business activity, preserve the supplier invoice and receipt records, and apply any required apportionment where goods are used partly for non-business or non-eligible purposes.
Input services used for exports
Input services can also generate ITC when they are used in the export business. Examples may include eligible freight, warehousing, professional, testing, repair, information-technology, communication or other operational services, depending on the facts and the applicable restrictions. The service must be received for business purposes, documented correctly and reported in accordance with GST requirements.
For a refund claim, the rules refer to net ITC availed on inputs and input services during the relevant period, subject to the rule-based exclusions. That wording is important: a credit may be valid for ordinary GST purposes yet not be counted in the same way for the accumulated-ITC refund calculation.
Capital goods require separate care
Capital goods should not automatically be included in the refund formula’s net-ITC figure. The statutory treatment and the facts of the claim must be checked before including GST paid on machinery, equipment or other capital assets. Keep capital-goods credits separately identifiable in the ledger and obtain current professional advice or a current rule-based interpretation before relying on them in a refund application.
Credits that remain blocked or require apportionment
Zero-rated status does not override section 17(5) of the CGST Act. Credits expressly blocked by that provision remain unavailable unless a specific statutory exception applies. The restriction must be tested against the nature and use of the expense, not against the fact that the exporter has overseas customers.
- Blocked categories: If the expense falls within a section 17(5) blocked-credit category, it cannot be claimed simply because it supports an export.
- Non-business use: Where goods or services are used partly outside the business, only the permitted business portion can be considered.
- Mixed supplies: Use the prescribed apportionment rules where an input or service supports both eligible and ineligible activities, or taxable and exempt supplies.
- Documentation failures: An invoice that does not meet GST requirements, an unreported purchase or an unsupported receipt can prevent or endanger the credit.
- Timing and reversals: Credits must be taken, reversed and reclaimed in accordance with the applicable statutory conditions and the return period in which the facts arise.
Maintain a clear schedule separating eligible inputs, eligible input services, blocked credits, capital goods and credits requiring apportionment. This makes both the monthly return and any refund reconciliation easier to defend.
Two export tax routes and their cash-flow effect
| Route | How the export is made | What is refunded | Important qualification |
|---|---|---|---|
| LUT or bond | Zero-rated supply made without payment of IGST | Eligible unutilized ITC, subject to section 54 and the refund rules | The broad accumulated-ITC route clearly supported for qualifying exports; the amount is formula-limited |
| Payment of IGST | IGST is paid on the zero-rated supply | Refund of IGST paid, where the route is available for the claimant and supply | Availability and operational conditions depend on current amendments, notifications and category restrictions |
The two routes are not interchangeable bookkeeping choices. Under an LUT or bond, the exporter preserves cash that would otherwise be paid as IGST but may accumulate credits and seek a refund of the eligible balance. Under the payment route, the exporter first pays IGST and seeks the applicable IGST refund instead. Before choosing, verify the current legal availability for the exporter, the type of supply, the destination and any notification-based limitation. CBIC materials have described both routes, but the payment route’s current scope must be checked against the latest law and notifications.
How the accumulated-ITC refund is calculated
For zero-rated supplies made without payment of tax under an LUT or bond, the refund rules prescribe a maximum amount based on export turnover, net ITC and adjusted total turnover. In simplified form:
Refund amount = (zero-rated turnover of goods + zero-rated turnover of services) × Net ITC ÷ Adjusted Total Turnover
This is a formula ceiling, not an automatic entitlement to the entire credit-ledger balance. The numerator and denominator must be built for the relevant claim period using the definitions and exclusions in the current rule.
Zero-rated turnover
For goods, use the export turnover recognized under the refund rules and reconcile it to the export invoices and shipping records. For services, the rules prescribe how export turnover is measured; the relevant service invoices, receipt of payment and other evidence must support the amount used.

Net ITC is the eligible ITC on inputs and input services availed during the relevant period, after applying the rule’s specified exclusions. Do not insert every credit appearing in the electronic ledger. Remove blocked, ineligible, reversed or otherwise excluded amounts and treat capital-goods credits only according to the current statutory treatment.
Adjusted total turnover
Adjusted total turnover supplies the denominator that allocates the eligible credit pool to the zero-rated turnover. It must be calculated using the rule’s definition and the same claim period. A mismatch between the turnover period, return figures and ledger period can produce an incorrect claim even when the exports themselves are genuine.
Restrictions that can reduce or prevent a refund
Export duty
Section 54(3) bars refund of unutilized ITC where the exported goods are subject to export duty. Check the tariff treatment of the actual goods rather than assuming that every export is eligible for accumulated-credit refund.
Drawback and other overlapping benefits
The law also contains restrictions involving specified drawback benefits and IGST-refund claims. The result depends on the particular benefit and the legal conditions attached to it. It is inaccurate to say that every drawback claim automatically bars every ITC claim. Identify exactly which drawback component or IGST refund is being claimed, then apply the current statutory restriction and notification.
Merchant-exporter concessions
Merchant exporters who purchase goods under specified concessional-rate notifications can face a narrower, rule-based refund treatment. The applicable CBIC circular addresses the claim category and procedure for ITC on those purchases and related eligible inputs or input services used for export. This is a conditional treatment for qualifying transactions, not an additional or universal credit available to all merchant exporters.
Documents and records to assemble
A defensible claim is built from a reconciled record set rather than from the ledger balance alone. Keep the following together for each claim period:
- GST registration details and the active LUT or bond, where the supply is made without payment of IGST.
- Purchase invoices for eligible inputs and input services, including supplier GST details, tax amounts and dates.
- Evidence that goods or services were received and used for the registered export business.
- Export invoices bearing the prescribed endorsement: either supply on payment of IGST or supply under bond/LUT without payment of IGST.
- Shipping bills, bills of export, export manifests or export reports for goods, together with transport and customs records where relevant.
- Service-export contracts, invoices, payment-realization evidence and other records needed to establish the service-export conditions.
- GSTR returns, purchase and sales registers, electronic credit-ledger extracts and a period-specific net-ITC schedule.
- Working papers for zero-rated turnover, adjusted total turnover, exclusions, reversals and any apportionment.
- Records identifying drawback, IGST refunds or other export incentives that could trigger an overlapping-benefit restriction.
How to file an LUT-route refund
- Confirm the route and period. Verify that the exports were made without payment of IGST under a valid LUT or bond and identify the exact tax period covered by the claim.
- Close the return data. Reconcile outward supplies, purchase credits, reversals and the electronic credit ledger to the relevant GST returns.
- Validate export evidence. Match each export invoice to shipping or customs evidence. For goods, the rules state that the refund application is filed after the export manifest or export report has been delivered.
- Compute the statutory formula. Determine zero-rated turnover of goods and services, net ITC and adjusted total turnover under the current refund rule. Exclude disallowed credits and amounts outside the claim period.
- Prepare the electronic application. Submit the prescribed FORM GST RFD-01 with the category-specific statements, declarations and supporting records required on the GST portal at the time of filing.
- Review the claim before submission. Check invoice numbers, shipping references, turnover totals, bank details, LUT or bond particulars and the amount requested against the formula ceiling.
- Track notices and preserve the file. Respond to any deficiency memo or clarification request with the same reconciled schedules and documentary trail, and retain the filed form and acknowledgements.
Portal fields, statement formats and documentary requirements can change. Use the current GST portal instructions and the latest CBIC notifications for the filing date rather than relying on an old screenshot or a prior-period workflow.

Common mistakes and how to correct them
Claiming the whole credit-ledger balance
The formula allocates eligible net ITC to zero-rated turnover. Recalculate the claim using the statutory numerator and denominator; do not request the unutilized ledger balance simply because it is visible online.

Mixing periods
Ensure that invoices, ITC availed, export turnover and adjusted total turnover belong to the same relevant period or are treated exactly as the current rule permits. A purchase register for one month paired with exports from another can distort the ratio.
Ignoring export-document timing
For goods, wait until the export manifest or export report has been delivered as required by the rules, then match the customs evidence to the invoice list before filing.
Assuming drawback always decides the outcome
Identify the precise drawback or IGST-refund benefit and apply the applicable restriction. Avoid both extremes: neither every drawback claim automatically disqualifies every ITC refund nor can overlapping benefits be ignored.

A practical eligibility checklist
- The claimant is GST-registered and made a qualifying zero-rated export.
- Each proposed credit relates to an eligible business input or input service.
- The tax invoice and receipt of supply are documented and reported correctly.
- No section 17(5) blocked-credit rule applies.
- Non-business, exempt or otherwise ineligible use has been apportioned or reversed.
- Capital-goods credits have been treated under the current statutory rule, not assumed to be part of net ITC.
- The export invoice carries the correct payment or LUT/bond endorsement.
- Shipping, manifest, service-export and payment evidence are available as applicable.
- Export duty, drawback and other IGST-refund interactions have been checked.
- The RFD-01 claim and calculation use the current portal format and refund formula.
What exporters should verify before relying on an answer
GST refund law is sensitive to amendments, notifications, export categories and the claimant’s records. In particular, verify the current availability of the payment-of-IGST route, the treatment of capital goods, merchant-exporter concessions, portal statements and any restriction connected with drawback or another IGST refund. A general explanation cannot determine the amount for a specific exporter without the invoices, returns, export evidence and claim-period calculations.
