The GST Network (GSTN) has made massive strides in automating refund processing, especially provisional claims under Rule 91. But here's the thing: the system is only as good as the data you feed it. And most businesses don't know what that means for their cash flow.
In this guide, we'll walk you through everything — from understanding how the 90% provisional GST refund 2026 process works, to filing the right forms, avoiding common rejections, and getting your money back faster. Our team at GetMyCA has helped 150+ clients successfully recover GST refunds ranging from ₹1.8 lakh to ₹4.2 crore.
GetMyCA is a leading business consultant in New Delhi, helping entrepreneurs and exporters with GST refunds and compliance since 2015. Our experts have processed 240+ refund projects across pharma, footwear, utensils, corrugated box, and rexine manufacturing sectors.
What is GST Refund Automation and the 90% Provisional Claim?
Under Rule 91 of the CGST Rules, businesses filing for a GST refund can receive 90% of the claimed amount on a provisional basis within 7 days of the acknowledgement of a complete application. This is designed to ease working capital pressure on exporters and inverted duty structure businesses while the full verification is underway.
Legal Framework Under CGST Act
The provisional refund mechanism is governed by Section 54(6) of the CGST Act, 2017, read with Rule 91 of the CGST Rules. The balance 10% is released after the proper officer completes documentary verification and is satisfied with the claim.
Post the 2024-2025 GSTN upgrades, the refund process is now largely automated through the GST portal (gst.gov.in). Applications, acknowledgements, deficiency memos, and payment orders are all system-generated — cutting down the human touchpoints that used to cause delays.
Who Is Eligible for a GST Refund in 2026?
Not every business can file a GST refund claim. Here's who qualifies under current rules:
Exporters of goods or services (zero-rated supplies) — with or without payment of IGST
Businesses with accumulated ITC due to an inverted duty structure (input tax rate higher than output tax rate)
UN bodies, embassies, and persons making supplies to Special Economic Zones (SEZs)
Businesses where excess tax was paid due to an error
Deemed exporters supplying to EOU/STPI/EHTP/BTP units
How to File a GST Refund Claim in India? (Step-by-Step, 2026)
Here's the exact process our team follows for clients — whether they're a corrugated box exporter in Delhi or a footwear manufacturer in Agra. Follow these steps carefully.
Log in to the GST Portal: Visit gst.gov.in and navigate to Services > Refunds > Application for Refund. Choose the correct refund type (ITC on exports, inverted duty structure, etc.).
Select the Tax Period: Pick the relevant monthly or quarterly period for which you're claiming the refund. Make sure your GSTR-1 and GSTR-3B for that period are filed and reconciled.
Upload Supporting Documents: Attach shipping bills (for exports), invoices, bank realisation certificates (BRCs), and the statement of invoices as applicable. Mismatch here is the #1 reason for deficiency memos.
Submit Form RFD-01: This is the primary refund application form. The system auto-populates certain fields from your GSTR-1 data. Review carefully before submitting.
Receive ARN and RFD-02 Acknowledgement: Within 15 days, if your application is complete, you'll get an Application Reference Number (ARN) and the RFD-02 acknowledgement. The 7-day provisional refund clock starts here.
Provisional Refund Credit (RFD-04): If eligible, 90% of the refund is credited to your bank account provisionally via Form RFD-04. This typically happens within 7 days of RFD-02.
Final Order and Balance Payment (RFD-06): After verification, the balance 10% is released through Form RFD-06. If there's a discrepancy, you'll receive an SCN (Show Cause Notice) instead.
Case Study: We helped a Delhi-based pharma exporter recover ₹38.2 lakh in IGST refund within 19 days using the automated route — compared to the 4-month wait they'd experienced previously. The key? Clean GSTR-1 data and pre-matched shipping bills.
What Documents Are Required for a GST Refund Claim?

Shipping bill amounts not matching GSTR-1 export figures — leading to system mismatch errors
BRC/FIRC submitted after filing instead of before — causing provisional refund holds
CA certificate not mentioning 'no double claiming of ITC' — mandatory wording post-2024
Incorrect bank account linked on GST portal — refunds get stuck in failed payment queue
How Much Does GST Refund Processing Cost in 2026?
Filing a GST refund yourself is technically free (no government fee). But the hidden costs of errors, delays, and working capital blockage are significant. Here's what the numbers actually look like.

For a business with ₹20 lakh blocked in GST refunds, a 60-day delay at a typical borrowing cost of 12% p.a. means ₹40,000+ in opportunity cost — far more than professional filing fees.
