There is no single “GST refund” route in India. The correct claim depends on why money or input tax credit became refundable: a zero-rated export or SEZ supply, input rates higher than output rates (inverted duty), an excess cash-ledger balance, tax paid above the legal liability, a wrong intra-State/inter-State classification, deemed exports, or an assessment, appeal or other statutory order. Most electronic claims are filed in FORM GST RFD-01, but each category has different eligibility tests, evidence and exclusions.
GST refund types at a glance
CBIC’s electronic refund framework groups claims by the event that created the refundable amount. The table below separates the refundable base and the person who normally claims it, so an unutilised ITC refund is not confused with a cash-ledger withdrawal or a tax overpayment.

| Refund category | What creates the refund | Typical claimant | Refundable base | Main evidence or control |
|---|---|---|---|---|
| Zero-rated export without payment of tax | Goods or services exported under a bond or Letter of Undertaking (LUT) | Exporter | Eligible unutilised ITC | Export invoices; shipping-bill or bill-of-export details for goods; invoice and remittance evidence for services |
| Export with IGST payment | IGST is paid on exported goods and the statutory export-return conditions are met | Exporter | IGST paid on the export | Shipping bill, valid GSTR-3/3B and export manifest/report |
| Supply to an SEZ unit or developer | Zero-rated supply to an eligible SEZ recipient | Usually the supplier, depending on the tax-payment route | IGST paid or eligible unutilised ITC | Invoices and SEZ endorsement or other prescribed proof |
| Inverted-duty refund | Input tax rates exceed output-supply rates, creating accumulated ITC | Registered supplier | Eligible unutilised ITC | Period-wise purchase and sales data; Rule 89(5) calculation |
| Deemed-export refund | A notified deemed-export supply where tax has been paid | Supplier or recipient, as allowed for the transaction | Tax paid on the qualifying supply | Deemed-export documents and proof of tax payment |
| Excess balance in electronic cash ledger | More money was deposited in the GST cash ledger than needed | Account holder of the ledger | Eligible cash balance | Ledger and payment records |
| Excess tax payment | Tax paid exceeds the amount legally due | Person who paid the tax | Excess tax, not merely unused ITC | Returns, invoices, liability reconciliation and payment proof |
| Wrong tax classification or an order | Tax paid as intra-State instead of inter-State, or vice versa; or a refund arises from assessment, provisional-assessment finalisation, appeal or another order | Supplier, recipient or person named in the order | Tax or amount specified by law or order | Original and corrected tax records, plus the relevant order |
CBIC Circular 125/44/2019-GST moved these categories into electronic FORM GST RFD-01 processing from 26 September 2019. The category selected in the application determines the statement, supporting documents and calculation that the tax officer can examine.

Export under LUT or bond: refund of unutilised ITC
An exporter can generally supply goods or services without charging IGST by exporting under a valid bond or Letter of Undertaking. The exporter then seeks a refund of eligible unutilised ITC accumulated during the relevant period. The amount is not an automatic repayment of every credit in the ledger: the statutory Rule 89 calculation and its exclusions apply.
#1 Best Overall
For goods, keep the export invoice matched to the shipping bill or bill of export. Customs must have the export manifest or export report before an export-goods refund application can be filed. For services, retain the export invoices and the applicable Bank Realisation Certificates (BRCs) or Foreign Inward Remittance Certificates (FIRCs) showing receipt of foreign exchange or the prescribed remittance evidence.
Export with IGST payment: shipping bill as the refund application
Under the alternative route, the exporter pays IGST and seeks its refund through the shipping-bill and return process. CBIC states that the shipping bill is treated as the refund application when the exporter has filed a valid return in Form GSTR-3/3B and the person in charge of the conveyance has furnished the export manifest or export report. In practical terms, an error in the return, shipping bill or manifest can stop the automated linkage even though the goods physically left India.
The IGST-paid route and the LUT route are not interchangeable for the same export. Do not claim an IGST refund on an export while also claiming the corresponding unutilised ITC or a drawback benefit that covers the same tax. Exported goods subject to export duty are excluded from the unutilised-ITC route. CBIC’s FAQ also identifies CGST/IGST drawback and an IGST refund on the same export as exclusions.

Service exporters normally use the LUT route when they do not charge IGST and claim eligible accumulated ITC. The refund file should connect each export invoice to the required remittance evidence, such as a BRC or FIRC, and to the period’s return data. A description such as “foreign client” is not a substitute for invoice-level evidence and the applicable export-of-service conditions.
Supplies to SEZ units and developers
Supplies to an eligible SEZ unit or developer are zero-rated, but the supplier still needs proof that the recipient is an SEZ unit or developer and that the goods or services were received for authorised operations. Where tax is charged and paid, the permitted refund route generally returns that tax; where the supply is made without tax, the supplier may seek eligible unutilised ITC. Obtain the prescribed SEZ endorsement and retain it with the invoice and return records.
What an inverted-duty refund means
An inverted-duty situation exists when the GST rate on inputs is higher than the rate on the outward supply. The business can accumulate ITC because its purchases carry more tax than it collects on sales. The refund addresses that eligible accumulation; it is not a refund of every credit balance held by the taxpayer.
Eligibility boundaries
- The claim concerns unutilised ITC attributable to the rate inversion and is calculated under Rule 89(5).
- Nil-rated or fully exempt outward supplies and other statutory exclusions do not become refundable merely because the ledger contains credit.
- The restriction discussed in CBIC Circular 135/05/2020-GST applies where the input and output supplies are the same. A rate difference alone should not be treated as a universal entitlement.
- Concessional-rate notifications can change the analysis. Check the notification governing the particular goods or services, not only the headline rate shown in an accounting system.
The formula is date-sensitive
Notification 14/2022-Central Tax amended the Rule 89(5) formula on 5 July 2022. CBIC Circular 181/13/2022-GST records that change. A spreadsheet or calculator built before that date may produce the wrong result, so apply the version of the rule and relevant notifications in force for the claim period.
Recommended Free Tools
Before filing, reconcile eligible input invoices, the output turnover used in the formula, credits already utilised, and the closing electronic credit-ledger balance. Preserve the working paper showing how the claimed amount was allocated to the inverted supplies; a single total without period and invoice support is difficult to defend.
A simple way to test the issue
Suppose a manufacturer buys an input taxed at 18 percent and sells the finished product at 5 percent. If the pattern persists, ITC can accumulate. That fact alone does not settle the claim: the taxpayer must still identify the qualifying supplies, remove excluded turnover and credits, apply the current Rule 89(5) method, and check whether a notification or the same-input/same-output restriction changes the result.
Excess cash, excess tax and excess ITC are different
Electronic cash-ledger balance
An electronic cash-ledger refund returns eligible money deposited into the GST cash ledger but not required to discharge tax, interest, penalty or other liabilities. It is a cash-balance claim. The supporting trail is the ledger, challans and liability reconciliation.
Tax paid in excess
“Excess tax” means tax was paid above the legal liability—for example, a return or payment calculation overstated the amount due. This is separate from an unused cash balance. Demonstrate the correct liability with invoices, amended records where permitted, returns and payment evidence, then claim the overpayment under the excess-tax category.
Unutilised ITC
An electronic credit-ledger balance is not cash. It can be refundable only under a statutory route such as zero-rated exports or inverted duty, subject to the applicable formula and exclusions. Selecting “cash ledger” when the amount is actually accumulated ITC sends the claim into the wrong legal category.
Other statutory refund grounds
Deemed exports
Deemed exports are notified domestic supplies treated specially for refund purposes even though the goods do not leave India. The supplier or recipient may claim where the law permits, but the file must establish the deemed-export status, tax payment and prescribed documentation.
Wrong intra-State or inter-State tax
If a supply was taxed as intra-State when it should have been inter-State, or the reverse, the original tax may be refundable after the correct tax is paid. Keep the original invoice, evidence supporting the correct place-of-supply treatment, the corrected tax payment and the return reconciliation together.
Assessment, provisional assessment and appellate orders
A refund can follow finalisation of a provisional assessment, an assessment order, an appellate decision or another order that directs or creates a repayment. The order is the foundation of the claim: quote its reference, calculate only the amount it covers and attach proof that any resulting liability adjustments have been made.

- Identify the legal trigger. Decide whether the claim is for an export, SEZ supply, inverted duty, deemed export, cash balance, excess tax, wrong tax classification or an order. Mark the relevant tax period and the person entitled to claim.
- Reconcile the underlying records. Match invoices to returns, ledger balances, shipping bills, remittances, SEZ endorsements, corrected tax payments or orders. Separate electronic cash-ledger money from electronic credit-ledger ITC.
- Check mutually exclusive benefits. For exports, confirm that the same goods or services are not receiving both an IGST refund and a drawback or unutilised-ITC refund that the law excludes.
- Prepare the category statement. Use invoice-period data for inverted duty, shipping-bill details for goods, invoice and BRC/FIRC details for services, and order or SEZ information where relevant.
- File RFD-01 electronically on the common portal. Select the exact refund reason, enter the period and amount, upload the prescribed statement and evidence, and submit subject to current portal instructions.
- Retain the complete audit file. Save the filed form, acknowledgement, calculation workbook, source invoices, ledger extracts and correspondence. The portal submission alone does not replace the underlying records.
- Respond to deficiencies promptly. If the officer requests clarification or issues a deficiency communication, answer the specific mismatch and correct the category or computation where required rather than uploading an unrelated document set.
Evidence checklist by refund type
- Exported goods: export invoices, shipping bills or bills of export, export manifest/report confirmation and return linkage.
- Exported services: invoices, contracts or service descriptions where needed, BRCs/FIRCs and the relevant return and ITC records.
- SEZ supplies: tax invoices, recipient details, authorised-operation endorsement and proof of tax payment or eligible ITC.
- Inverted duty: purchase and sales registers, rate mapping, Rule 89(5) working, turnover figures, credit-ledger extracts and exclusion checks.
- Cash-ledger refund: electronic cash-ledger statement, challans and outstanding-liability reconciliation.
- Excess tax: original and corrected liability calculations, invoices, returns and payment proof.
- Wrong tax head or order-based refund: place-of-supply analysis, corrected tax payment and the complete assessment, provisional-assessment or appellate order.
Common mistakes and how to correct them
Choosing the wrong refund reason
An ITC accumulation is not an excess-cash claim, and an overpayment is not automatically an inverted-duty claim. Reclassify the amount before submission and make the ledger treatment agree with the selected category.
Missing export-system linkage
For goods, verify that the shipping bill number, invoice data, return and export manifest are consistent. For services, check that the invoice and BRC/FIRC cover the same period and recipient. Resolve spelling, invoice-number and date mismatches before filing.
Using an obsolete inverted-duty calculator
Check the 5 July 2022 Rule 89(5) amendment and later notifications applicable to the goods or services. Preserve a dated version of the formula used and document every exclusion.

Ignoring limitation and current portal directions
Refund claims are subject to statutory time limits and procedural instructions that can change. Confirm the limitation rule for the specific ground, the applicable period definition and the portal’s current document requirements immediately before filing.
A practical decision path
- Did goods or services leave India, or was the supply made to an SEZ? Start with the zero-rated export or SEZ route.
- If not, did input rates exceed output rates and create eligible ITC? Test the inverted-duty rules and current Rule 89(5) formula.
- If the amount is money in the cash ledger, use the cash-balance route; if tax liability was overstated and paid, use excess tax.
- If the wrong tax type was paid, document the intra-State/inter-State correction.
- If an authority’s order creates the amount, file against that order and claim only what it supports.
- If none fits, identify the precise statutory “any other” basis before using that category.
The safest claim is therefore the narrowest accurate one: identify the event, use the matching RFD-01 category, calculate only the legally refundable base, and attach evidence that lets the officer trace the amount from invoice or order to return and ledger.
