CBIC Notifies Faster, System-Based GST Refunds: 90% Provisional Refund for Exporters from 1 November 2026

Exporters have long complained that the cash they are owed back as GST refunds takes too long to arrive, tying up working capital that could fund the next shipment. The Central Board of Indirect Taxes and Customs (CBIC) has now moved to fix the process in software rather than in paperwork. Notification No. 05/2026-Central Tax, dated 26 October 2026, amends the Central Goods and Services Tax (CGST) Rules to make refunds faster and largely automatic — most notably a system-generated 90% provisional refund for low-risk export (zero-rated) and inverted-duty claims. The core changes take effect 1 November 2026, with the amended Rule 89(2) and the simplified FORM GST RFD-01 following on 1 December 2026.

This is the rules-level step that turns the 57th GST Council's refund recommendations into operating law. For exporters, it is the single most important working-capital change of the quarter.

What Happened

Notification 05/2026-Central Tax amends CGST Rules 86, 89, 90, 91 and 92 to compress and automate the refund workflow:

• 10-day acknowledgement (down from 15). The proper officer must issue an acknowledgement in FORM GST RFD-02, or a deficiency memo in RFD-03, within 10 days of a refund application being filed.
• Deemed acknowledgement. If neither an acknowledgement nor a deficiency memo is issued within those 10 days, the portal deems the application acknowledged. The 60-day clock under Section 54(7) of the CGST Act then runs from the date of filing.
• Automatic 90% provisional refund. For claims flagged low-risk by the system — covering zero-rated supplies (exports) and the inverted duty structure — the portal generates the provisional refund order in FORM GST RFD-04 within three working days of acknowledgement, without an officer re-validating the claim.
• Auto-sanction of excess cash ledger balance. Refund of a balance lying in the electronic cash ledger is generated by the system in RFD-06, after adjusting any outstanding demand, with the payment order (RFD-05) issued through the portal.
• Simplified RFD-01. From 1 December 2026, the refund application form is simplified and scanned-document uploads are trimmed for zero-rated and inverted-duty claims.

Why This Matters

Under the old flow, a refund could sit for weeks before an officer even acknowledged it, and the full amount was released only after manual scrutiny. By making a 90% provisional release the default for clean, low-risk export claims, CBIC shifts the burden: the money moves first, and detailed verification happens around it. For an exporter running on letters of credit and tight shipment cycles, getting 90% of a refund within days of acknowledgement — instead of a lump sum months later — is a direct improvement to cash flow and borrowing costs.

The risk-based design is the key. The system decides who is "low-risk," so clean compliance history, matched invoices and consistent filings are what unlock the fast lane.

Who's Affected

• Merchandise exporters claiming refund of accumulated input tax credit (ITC) on zero-rated supplies made without payment of IGST (under LUT/bond).
• Exporters and manufacturers with an inverted duty structure (inputs taxed higher than outputs) claiming accumulated-ITC refunds.
• Service exporters filing zero-rated refund claims.
• Any registered person with an excess balance in the electronic cash ledger.

What Exporters Should Do Now

• Confirm whether your refund claims are flagged low-risk on the GST portal; resolve any mismatches, red flags or pending demands that could push you into manual review.
• Reconcile GSTR-1, GSTR-3B, shipping bills and eBRC/realisation data so that invoice and export data match cleanly before you file.
• Clear any outstanding demands — the system adjusts them before releasing a provisional or cash-ledger refund.
• Brief your accounts team that acknowledgement (or deemed acknowledgement) now lands in 10 days, so the 60-day sanction clock starts sooner; track it.
• From 1 December 2026, use the simplified RFD-01 and expect fewer document uploads for zero-rated and inverted-duty claims.
• Treat the 90% provisional refund as provisional: keep documentation ready, because the remaining 10% and any final adjustment still follow verification.

The Bigger Picture

This notification is part of a wider CBIC package issued around 26–27 October 2026 to operationalise the 57th GST Council's recommendations — covering refunds, registration, input tax credit and adjudication. For exporters, the refund-automation piece is the one with the most immediate commercial effect, and it sits alongside the RBI's new FEMA 2026 export-import regime and the upgraded eBRC in reshaping how export proceeds and tax credits are tracked and returned. The direction of travel is clear: fewer manual touchpoints, more system-driven decisions, and faster release of legitimate refunds — provided your data is clean.

Frequently Asked Questions

When does the 90% provisional refund start? The amendments to Rules 86, 89 (except 89(2)), 90, 91 and 92 take effect 1 November 2026. The amended Rule 89(2) and the new simplified FORM GST RFD-01 apply from 1 December 2026.

Is every export refund eligible for the 90% provisional release? No. It applies to claims the system assesses as low-risk for zero-rated and inverted-duty cases. Higher-risk claims still go through officer scrutiny.

What is "deemed acknowledgement"? If the officer does not issue an acknowledgement or a deficiency memo within 10 days of filing, the portal treats the claim as acknowledged automatically, and the statutory sanction timeline starts from the filing date.

Does this change the amount of refund I am entitled to? No. It changes the speed and mechanics of release, not the underlying eligibility or quantum.

Conclusion

For exporters, Notification 05/2026-Central Tax is about one thing: getting your own money back faster. The upside is real — up to 90% released within days for clean claims — but it rewards exporters whose filings reconcile and whose risk profile stays low. The weeks before 1 November are the time to tidy up mismatches so your first post-reform refund lands in the fast lane.
