Last updated: 15 April 2026. If your business has excess Input Tax Credit stuck because of exports, inverted duty structure, or overpayment, you can claim a GST refund. The whole process runs through Form GST RFD-01 on the GST portal. For export and inverted duty claims, 90% of the refund gets provisionally credited within 7 days of acknowledgment.
Applicability Note: This guide is based on GST refund provisions under Section 54 of the CGST Act and Rules 89-96 of the CGST Rules as applicable in April 2026. Refund procedures and validations on the GST portal are updated periodically. Always verify the current position on gst.gov.in or with a GST professional before filing.
Who should care?
- Exporters of goods and services — both with and without payment of IGST
- Manufacturers and traders with inverted duty structure (input tax rate higher than output tax rate)
- Businesses that made excess tax payments or have surplus in the electronic cash ledger
- Suppliers to SEZ units and developers
1. Types of GST Refunds You Can Claim
Section 54 of the CGST Act covers refund of tax in several situations. The refund type you select in Form RFD-01 has to match your actual claim. Selecting the wrong type is one of the most common reasons applications get rejected.
| Refund Type | Who Can Claim | Rule | Key Requirement |
|---|---|---|---|
| Export with IGST payment | Exporters who paid IGST on exports | Rule 96 | Shipping bill filed, IGST shown in GSTR-1 Table 6A |
| Export without tax payment (ITC refund) | Exporters under LUT/Bond | Rule 89 | Valid LUT (Form RFD-11) for the FY, export invoices in GSTR-1 |
| Inverted duty structure | Businesses where input tax > output tax | Rule 89(5) | Accumulated ITC due to rate inversion, not blocked goods |
| Excess cash ledger balance | Anyone with surplus in electronic cash ledger | Section 54(1) | Balance visible in cash ledger on the portal |
| Supplies to SEZ | Suppliers to SEZ units/developers (without IGST) | Rule 89 | SEZ endorsement on invoices |
| Deemed exports | Suppliers to EOU, advance authorisation holders, etc. | Rule 89 | Endorsement from the recipient |
2. Step-by-Step: How to File Form GST RFD-01
Step 1: Renew your LUT (for exporters)
If you export without payment of IGST, you must have a valid Letter of Undertaking (LUT) for the current financial year. File Form GST RFD-11 on the portal before filing your first export refund of the year. LUTs expire every 31 March — renew by April each year.
Step 2: Log in and navigate to the refund section
GST Portal → Services → Refunds → Application for Refund → Select the relevant tax period.
Step 3: Select the correct refund type
This is critical. Read the dropdown options carefully. For exports without IGST, select "Refund of unutilised ITC on account of export without payment of tax." For inverted duty, select "Refund of unutilised ITC on account of accumulation due to inverted tax structure."
Step 4: Fill in turnover and tax details
The portal auto-populates some fields from your GSTR-1 and GSTR-3B. Verify each number manually — the auto-populated data can have discrepancies that cause rejection.
Step 5: Upload supporting documents
- Exports: Shipping bills, FIRC/BRC (bank realisation certificate for services), invoice copies
- Inverted duty: Statement of invoices (Statement 1A from the portal), purchase invoices showing higher GST rate
- Claims above Rs 2 lakh: Chartered Accountant's certificate certifying no unjust enrichment
Step 6: Submit and note the ARN
Sign with DSC or EVC and submit. You receive an ARN (Application Reference Number). Save it — you will need it to track your refund status.
3. Refund Processing Timeline
| Stage | Timeline | Form |
|---|---|---|
| Acknowledgment by officer | Within 15 days of filing | RFD-02 |
| Provisional refund (90%) | Within 7 days of acknowledgment | RFD-04 |
| Deficiency memo (if documents incomplete) | Within 15 days | RFD-03 |
| Final order | Within 60 days of filing | RFD-06 |
| Payment credited to bank | After RFD-05 payment order | RFD-05 |
90% provisional refund under Section 54(6) applies to export refunds and inverted duty structure claims. In practice, most of your money comes back within 3 weeks if the documentation is complete.
4. The 7 Most Common Refund Mistakes (and How to Avoid Them)
Mistake 1: Selecting the wrong refund type
The RFD-01 dropdown has multiple options that sound similar. Selecting "excess cash ledger" when you meant "ITC refund for exports" will get your application rejected. Double-check the category before submitting.
Mistake 2: Expired or missing LUT
Exporters filing zero-rated supply refunds without a valid LUT for the current FY. The LUT (Form RFD-11) is valid for one financial year only — renew it every April. Filing a refund without a valid LUT can delay processing by months.
Mistake 3: GSTR-1 and GSTR-3B mismatch
If the turnover or tax amounts in your GSTR-1 do not match GSTR-3B, the portal flags your application. Reconcile both returns before filing the refund claim.
Mistake 4: Including blocked ITC under Section 17(5)
ITC on motor vehicles, food and beverages, club memberships, and other items blocked under Section 17(5) cannot be part of a refund claim. Maintain a separate ledger for blocked credits and exclude them from the refund computation.
Mistake 5: Missing bank realisation certificate (for service exports)
For service export refunds, the FIRC or BRC from your bank is mandatory proof that foreign exchange was received. Without it, the refund is held until realisation is proven.
Mistake 6: FOB value mismatch with Shipping Bill
In practice, the GST portal cross-validates the FOB value declared in the Shipping Bill against the taxable value reported in GSTR-1. Significant mismatches between these values commonly trigger deficiency memos or delays in processing, and in some cases lead to outright rejection. Ensure your export invoices, GSTR-1 declarations, and Shipping Bills all report consistent values. If a discrepancy exists due to currency conversion or amendment, document the reason clearly in your refund application.
Mistake 7: Filing after the 2-year deadline
Under Section 54(1), the refund application must be filed within 2 years from the relevant date. For goods exports, the relevant date is the date of export (date the ship/aircraft leaves India). For services, it is the date of receipt of foreign exchange or date of invoice, whichever is later. For inverted duty, it is the end of the financial year. Miss this deadline and the claim is permanently time-barred.
5. How to Track Your Refund Status
Login to the GST portal → Services → Refunds → Track Application Status → Enter your ARN. The portal shows the current stage: Filed → Acknowledged → Provisional Refund Sanctioned → Final Order → Payment Credited.
An automated refund tracking dashboard is now available on the portal that shows all stages with timestamps.

Frequently asked questions
What is the minimum GST refund amount I can claim?
The refund amount must be at least Rs 1,000 per tax head (CGST, SGST, or IGST). Claims below this threshold are not processed.
Can I get a GST refund for inverted duty structure on all goods?
No. The government has notified certain goods where inverted duty refund is not available — most notably, items like woven fabrics and knitted fabrics where the inversion was created by rate changes. Check the current notification list on cbic-gst.gov.in before filing.
How long does a GST refund take to get credited to my bank?
If documentation is complete, the 90% provisional refund should reach your bank within 3-4 weeks of filing (7 days for acknowledgment + 7 days for provisional sanction + bank processing). The remaining 10% is released after the final order within 60 days. In practice, delays beyond 60 days are common if there are deficiencies or queries.
What should I do if my GST refund is rejected?
The rejection order (Form RFD-06) must state the reasons. You can file an appeal before the Appellate Authority within 3 months of the rejection order. Review the reasons carefully — many rejections are procedural (wrong type, missing documents) and can be avoided by re-filing correctly.
Do I need a CA certificate for every refund claim?
A Chartered Accountant's certificate is mandatory only for claims exceeding Rs 2 lakh. The certificate must confirm that no unjust enrichment has occurred — meaning the tax burden was not passed on to the buyer. For claims below Rs 2 lakh, a self-declaration is sufficient.
