A delayed Indian GST export refund usually traces to one of four things: the wrong refund route, inconsistent shipping-bill and return data, an incomplete portal workflow, or a formal verification or deficiency process. First establish whether you exported goods with IGST paid (the Rule 96 route) or exported without payment and are claiming accumulated input tax credit (the Rule 89 route). The documents, systems and authority handling the claim differ, so troubleshooting the wrong route can create further delay.
Start by identifying which export-refund process applies
“GST export refund” is not one single application. Indian GST law uses two principal mechanisms for exports of goods, and they do not use the same trigger or data flow.

| Question | Goods exported with IGST paid | Exports made without payment of tax |
|---|---|---|
| Primary legal route | Rule 96 | Rule 89 |
| How the claim starts | The shipping bill becomes the refund application after the required export report or manifest and a valid GSTR-3B are available. | The exporter files electronic FORM GST RFD-01 for refund of accumulated or unutilized ITC. |
| Records that control the claim | Shipping bill, export manifest or report, GSTR-1 export-invoice data and GSTR-3B. | RFD-01, the relevant returns, invoices and evidence supporting the accumulated ITC and zero-rated supplies. |
| Principal processing flow | Customs-linked electronic processing, subject to possible tax-officer or Customs verification. | Processing by the jurisdictional tax authority under the refund procedure. |
| Typical first diagnostic | Reconcile shipping-bill fields with GSTR-1 and confirm the export report and GSTR-3B are present. | Read the RFD-01 record and any deficiency memo, then check the ITC and supporting-return figures. |
For services exports, Rule 96 directs the applicant to use RFD-01 and the Rule 89 procedure rather than the shipping-bill mechanism used for goods. Do not assume that a services claim will move through the same Customs data path as a goods claim.

The shipping bill is not immediately a complete application
Under Rule 96, the shipping bill is treated as the refund application only after the export manifest or report has been filed and the exporter has furnished a valid GSTR-3B return. The shipping-bill information and the export invoices reported in GSTR-1 are sent through the Customs-designated electronic system for confirmation.
#1 Best Overall
A mismatch changes the deemed filing date
If the shipping bill and GSTR-1 information do not match, the application is deemed to have been filed only on the date the mismatch is corrected. This is why a claim can appear to have been “submitted” from the exporter’s perspective while the legal filing date used for processing is later. Check invoice number, date, taxable value, tax amount, port and other identifying fields against the exact export documents, then correct the record that is wrong rather than editing a matching record merely to force a result.
Customs credits the registered bank account after processing
Once the required return and export information is received, Customs processes the claim and credits the amount to the bank account in the exporter’s registration particulars that was intimated to Customs. A bank-account discrepancy can therefore become a payment-stage problem even after the underlying export data has been accepted.
How the Rule 89 unutilized-ITC refund differs
When exports are made without payment of tax, the exporter normally claims the refund of unutilized ITC electronically in FORM GST RFD-01. The application is evaluated as a refund claim, not as an automatic shipping-bill payment. The officer may examine the period, eligible turnover, net ITC, invoices, return data and other supporting records under the Rule 89 process.

Conversely, a clean RFD-01 does not repair a Rule 96 mismatch, because the two routes draw on different records and processing systems.
Why GST export refunds are delayed or blocked
1. Export or return information is missing
Rule 96 requires both a valid GSTR-3B and the export manifest or report. It also relies on export invoices in GSTR-1 reaching Customs in a form that matches the shipping bill. If one return is not filed, an export report is absent, or an invoice is omitted or reported differently, the electronic chain cannot complete.
2. The portal cannot find IGST paid for the period
The GST Portal message “No Outward Supply tax file for the selected return period” indicates that IGST was not shown as paid on the relevant export supply in GSTR-3B for that period. Review the filed return, not just a saved draft, and verify that the export supply and IGST amount were reported in the period selected for the refund workflow. If the return itself is wrong, use the correction method available for that return and period; do not create a duplicate refund application to compensate for missing tax data.
3. A draft or earlier application already exists
The portal may prevent a second claim for the same category and period when an earlier application is saved or submitted. The message “Refund has been already applied for this month. Kindly exclude” can also appear when the selected period overlaps an existing claim. Go to Services → Refunds → My saved/filed application and inspect both drafts and submitted applications. Record the ARN, category, period and status before deciding whether to continue, withdraw where permitted, or respond to the existing record.

4. A preceding period has not been dealt with
For the same refund type, the portal guide generally expects claims to be filed sequentially by return period, subject to stated exceptions. A later-period claim may therefore be blocked if an earlier period has neither a claim nor the filing the portal expects. Check the current on-screen guidance, identify the missing period and determine whether a substantive claim or a nil filing is appropriate. Portal behavior can change, so rely on the instruction displayed for the current filing rather than an old screenshot or an informal workaround.
5. The officer has issued an RFD-03 deficiency memo
An RFD-03 is not a request to keep resubmitting the same application. Rule 89 directs the applicant to rectify the deficiencies listed in the memo and file a fresh refund application. The portal guidance confirms that a fresh application can cover the same period after an RFD-03.
6. The claim has been withheld for verification
Rule 96 permits withholding in several situations, including a request from the jurisdictional tax officer, a Customs determination involving violation of export law, or a risk-based decision that the exporter’s credentials, including ITC, should be verified. Certain withheld claims are transmitted electronically to the tax officer for processing under Rule 89. A “withheld” status therefore requires you to identify the stated hold basis and the authority named in the communication; it is not evidence that the refund has been finally rejected.
A practical resolution workflow
- Classify the claim. Confirm whether the shipment was made with IGST paid under Rule 96 or without payment of tax with an RFD-01 claim under Rule 89. For a services export, use the RFD-01/Rule 89 path.
- Capture the case record. Write down the ARN, refund category, return period, date of filing, latest portal status and every formal communication, including an RFD-03, notice or withholding message. “Pending” alone does not establish the reason for delay.
- Reconcile the source records. For a Rule 96 goods claim, compare each shipping bill with the corresponding GSTR-1 export invoice and verify that the relevant GSTR-3B was filed and that the export manifest or report is available. Correct the specific mismatch identified by the system or authority.
- Inspect the portal workflow. Open Services → Refunds → My saved/filed application. Check for an existing draft, a submitted application for the same category and period, a missing earlier-period filing, or a period in which IGST was not reported as paid on the export supply.
- Handle an RFD-03 correctly. Make a deficiency-by-deficiency checklist, attach the corrected records and file a fresh application rather than a duplicate. Preserve the original ARN, filing date, RFD-03 date and fresh-application date.
- Follow a withholding communication. Identify whether the hold refers to Customs, the jurisdictional tax officer or risk-based verification. Respond through the channel specified in the communication and provide only the records requested, with a reconciliation that lets the officer trace each export and ITC figure.
- Check payment details. For a Rule 96 claim that has cleared processing, verify the bank account in the exporter’s registration particulars that was intimated to Customs. A successful data match does not make an incorrectly registered account payable.
What to do after an RFD-03 deficiency memo
Read the memo as a correction list
Separate factual errors from missing evidence. For example, one deficiency may concern an invoice or return figure, while another may require a document or explanation. Correct the underlying return or record where law and the filing system permit it, and prepare a short index showing where each correction is supported.
File fresh, not duplicate
After rectification, submit the fresh RFD-01 application for the same period through the refund workflow. Do not treat the old ARN as still live merely because it remains visible in the portal. Keep both records so that an officer can connect the fresh claim to the memo.
Rank #4
Preserve the limitation calculation
Rule 89 excludes the period between filing the original application and communication of the deficiency memo when calculating the two-year period for the corrected fresh claim. Retain proof of both dates. This does not remove the need to file within the applicable statutory period; it provides a specific exclusion when that period is calculated.
How to interpret common portal situations
| Portal situation | What it usually signals | Next check |
|---|---|---|
| “Refund has been already applied for this month. Kindly exclude” | An existing claim or draft overlaps the selected category and period. | Review My saved/filed application, then continue the existing record or select a period that is not already claimed. |
| “No Outward Supply tax file for the selected return period” | The system cannot find IGST reported as paid on the relevant export supply in GSTR-3B. | Open the filed GSTR-3B for that period and reconcile the export supply and IGST amount. |
| Later period cannot be selected | A preceding period may be missing for the same refund type. | Check current sequential-filing instructions and deal with the earlier period before filing the later one. |
| Claim shown as withheld | Customs, a tax officer or risk controls have triggered verification or another Rule 96 hold. | Read the hold communication and respond to the authority and basis specified there. |
These messages are workflow clues, not final legal findings. The ARN record and formal communication control the case-specific explanation.
When interest may be available
Section 54(5) of the CGST Act provides interest where a qualifying refund is not paid within 60 days of receipt of the application. The rate is set by notification, and statutory conditions apply. The 60-day rule is therefore not an automatic promise of interest on every delayed export refund. Establish the correct route, receipt date, completeness of the application and any deficiency or withholding event before making an interest claim. A Rule 96 mismatch that defers the deemed filing date can materially affect that analysis.

For a prolonged hold, a disputed reconciliation or an RFD-03 requiring substantive correction, an Indian GST practitioner or tax adviser who routinely handles export refunds can help prepare the response and coordinate with the named authority. They cannot replace the underlying return and Customs records, so engage them with the complete case file rather than only a screenshot of the status.
Final decision rule
Do not submit another refund application until you know which route you are using and whether an application already exists. Rule 96 goods claims are driven by consistent shipping-bill, manifest, GSTR-1 and GSTR-3B data; Rule 89 claims depend on the RFD-01 and the evidence supporting unutilized ITC. Correct the exact data or deficiency identified, preserve the dates that govern filing and interest, and follow the authority named in any verification or withholding communication.
