Airline Refunded GST to Passengers on Cancelled Tickets — GSTAT Says It Can Now Claim That Tax Back

When a flight gets cancelled, the airline doesn’t just refund the fare — it refunds the GST charged on it too. That created a genuine compliance puzzle for one carrier for a stretch of the COVID-19 period, and the GST Appellate Tribunal’s Ernakulam Bench has just settled how that tax comes back to the business that fronted it.

Between October 2019 and March 2021, Singapore Airlines’ Kochi branch saw flight cancellations push its refund obligations above its ticket sales for several tax periods. GSTR-3B doesn’t permit a negative net value, so the airline couldn’t fully net its credit notes against output tax within the return itself. It filed eight separate refund claims totalling ₹45,92,528 under the “excess payment of tax” category in Form RFD-01. The adjudicating authority rejected all eight, citing insufficient evidence of excess payment and no proof the refunded GST had actually reached passengers; the first appellate authority upheld that rejection, additionally citing a time bar under Section 34(2) and the absence of a one-to-one link between the airline’s agents and individual passengers.

The Tribunal, hearing all eight appeals together, disagreed on every count. It found that the ticket number and passenger name — present across the tax invoice, the credit note and the refund voucher — do establish exactly the documentary link the lower authorities said was missing. It found no unjust enrichment, since the full fare including GST was actually returned to passengers rather than retained by the airline. And because the tickets were overwhelmingly sold directly to individual travellers (B2C), the usual concern about a downstream recipient needing to reverse input tax credit didn’t arise for the bulk of the claim.

Sidebar: the procedural point that makes this case useful beyond airlines. The Tribunal confirmed that RFD-01 under the “excess payment of tax” category — rather than trying to force a negative adjustment through GSTR-3B — is the correct route under CBIC Circular No. 137/07/2020-GST wherever a taxpayer has no output liability left to absorb a credit note. That’s a fact pattern that comes up well beyond the airline sector, anywhere cancellations or returns routinely exceed a period’s fresh sales — hospitality, event ticketing, and subscription businesses with high cancellation volumes, among others.

Why It Matters

This is a useful precedent for any GST-registered business that issues credit notes for cancelled or returned supplies and finds itself unable to absorb the full value within GSTR-3B in the same period — a documentary trail built around a clear, traceable identifier (here, the ticket number) can carry a refund claim even without a formal, individually-signed acknowledgment from each end customer. It also reaffirms that the Section 34(2) proviso amended by the Finance Act 2025 (effective 1 October 2025) does not reach back to apply to transactions and refund claims from the pre-amendment period — relevant to any taxpayer with a live dispute over an older tax period.

Key Takeaways

• GSTAT Ernakulam allowed all eight appeals (APL/3/ERN/2026 to APL/9/ERN/2026 and APL/30/ERN/2026), setting aside the Joint Commissioner (Appeals)’s rejection.
• Refund claim: ₹45,92,528 across the eight periods, filed as “excess payment of tax” under Form RFD-01, per CBIC Circular No. 137/07/2020-GST.
• Ticket number + passenger name across the tax invoice, credit note and refund voucher was held sufficient documentary proof — no separate passenger acknowledgment required.
• No unjust enrichment found: the full fare, including GST, was actually returned to passengers.
• The Finance Act 2025 amendment to the Section 34(2) proviso (effective 1 October 2025) does not apply retrospectively to this pre-amendment period.
• The department has been directed to process the refund within two weeks, with interest from the date of the original application until payment.

Practical Implications

Any business issuing a high volume of cancellation-driven credit notes — not just airlines — should treat this order as a reminder to build and retain the specific documentary chain the Tribunal relied on: a consistent identifier (a ticket, booking or order number) linking the original tax invoice, the credit note, and proof that the GST component was actually passed back to the customer, not merely the base fare. Where a period’s credit notes exceed that period’s output liability, RFD-01 under “excess payment of tax” is the established route — attempting to force the adjustment through GSTR-3B’s return mechanics, which does not accept negative values, is the wrong path and risks exactly the kind of rejection seen at the first two levels here.

Action Checklist

• For clients in cancellation-heavy sectors (travel, hospitality, events, subscriptions): audit whether any past period’s credit notes exceeded that period’s output tax liability, and whether a refund claim was ever filed for the resulting excess.
• Where such a claim exists or is contemplated: confirm the documentary trail links a consistent identifier (ticket/booking/order number) across the tax invoice, credit note and proof of refund to the end customer — this is the evidentiary standard the Tribunal applied.
• File any such claim under Form RFD-01, “excess payment of tax” category, per CBIC Circular No. 137/07/2020-GST — not through GSTR-3B adjustment.
• For claims relating to periods before 1 October 2025, do not apply the Finance Act 2025 amendment to the Section 34(2) proviso — this order confirms it operates prospectively only.

FAQs

Does this order apply only to airlines?
No — the Tribunal’s reasoning turns on general GST refund principles (documentary linkage, no unjust enrichment, the correct refund route where GSTR-3B can’t absorb a negative value) that apply to any registered person with a comparable fact pattern, not on anything specific to air travel.

Can a business use this to claim refunds for any period going back indefinitely?
No — ordinary limitation periods under Section 54 continue to apply; this order addresses the merits of claims that were timely filed, and separately confirms that the 2025 amendment to Section 34(2) does not apply retrospectively. It does not reopen time-barred claims.
