GST on air travel in India has a split that confuses even experienced finance teams: domestic flights attract 5% GST (effectively no ITC for most businesses because the 5% rate is collected net of ITC at the airline end), while international flights issued through Indian agents can attract 18% GST on the agent’s commission or service fee. Claiming ITC incorrectly on group flight invoices is one of the more common causes of demand notices from GST officers. Here’s what actually applies.

TL;DR — the short answer

For domestic group flights in India: GST is levied at 5% (economy) or 12% (business class) on the base fare. The 5% rate is a ‘blocked credit’ rate under GST law — airlines collect and pay it but businesses generally cannot claim input tax credit on it for business travel. The 12% business-class fare does allow ITC in principle, but comes with its own conditions. For international flights booked through an Indian travel agent or OTA: the agent’s service fee or commission is typically subject to 18% GST, and ITC on that 18% component can be claimed by a registered business buyer — subject to GSTR-2B matching and the standard conditions. The air ticket fare itself (international sector) is exempt from GST on the base fare portion. This split is widely misunderstood and regularly causes ITC disallowance in group travel invoices. Always verify the treatment with your company’s CA or tax consultant, and cross-check on the CBIC website (cbic.gov.in).

GST structure on domestic flights — why the 5% is mostly not claimable

Under Schedule II to the CGST Act and the GST rate notification, passenger air transport by domestic carriers (economy class) is taxed at 5% GST. This sounds like a standard GST rate on which you should be able to claim ITC — but there’s a specific block under Section 17(5) of the CGST Act that restricts ITC on ‘travel benefits extended to employees on vacation’, which is how routine business travel can sometimes fall into a grey zone.

More importantly, the 5% domestic air GST operates as an effective composite rate. Airlines collect 5% but the ITC chain between airlines and their input vendors is structured such that very little GST credit flows up to the airline level in the first place (airlines have significant exempt and zero-rated services mixed with taxable ones). The legislative intent of the 5% economy domestic rate is explicitly to be collected without enabling a full ITC cascade.

For a company booking group domestic flights:

The invoice from the airline or OTA will show 5% CGST+SGST or 5% IGST on the fare. For an economy group ticket, this is generally not available as ITC for the purchasing business under most interpretations of Section 17(5) and the related notifications. Your company’s CA should confirm the current prevailing CBIC clarifications — GST policy has seen multiple amendments and circulars.
If the group travels business class domestically, the rate is 12% and ITC conditions are different (12% does not fall under the same blocked-credit analysis as 5%). But business-class domestic is uncommon for most group travel.
OTA or agent service fees on domestic bookings are usually subject to 18% GST separately and ITC on those 18% service fees is generally available to registered businesses, subject to GSTR-2B matching.

GST on international flights — the 18% that confuses everyone

International air travel (where the origin or destination is outside India) is technically zero-rated for GST on the base fare — the airline’s revenue from carrying passengers internationally is treated as an export of service and does not carry Indian GST on the ticket fare. This is why your Air India or IndiGo international ticket fare does not show 5% or 18% GST on the actual ticket line item.

What does carry 18% GST is the Indian travel agent’s service fee or OTA platform charge on that international booking. When you book an international group flight through an Indian IATA agent or an OTA like MakeMyTrip or Cleartrip, their service fee / convenience fee / commission component is subject to 18% GST, and that 18% invoice is what a business buyer can potentially claim as ITC.

This creates an important practical implication for corporate travel desks managing group international bookings: you want to ensure the agent’s invoice separately and clearly shows the 18% GST on the service fee, with a valid GSTIN on the invoice, so the credit is traceable in GSTR-2B. Invoices that lump the service fee into an opaque ‘total’ make ITC claims difficult and often lead to disallowance during scrutiny.

GSTR-2B matching: the step most companies get wrong

GSTR-2B is the auto-populated ITC register that shows what your suppliers have reported as GST collected from you in their GSTR-1 filings. ITC claims are now validated against GSTR-2B — if the amount does not appear in your GSTR-2B, claiming it in GSTR-3B opens you up to scrutiny and potential demand notice under Rule 36(4) of the CGST Rules.

For group flight bookings, the GSTR-2B matching problem often arises in these scenarios:

Multiple invoice fragments: A group booking of 15 pax sometimes generates individual tickets (15 separate invoices) or a group invoice depending on the airline’s billing system. If your accounts team books 15 individual tickets but the airline reports a single consolidated invoice in GSTR-1, there’s a mismatch to reconcile.
Booking through sub-agents: If your company’s travel desk uses a sub-agent (who in turn buys from an IATA consolidator), the GST liability and invoice chain can have multiple layers. The invoice you receive may not be the entity reporting in GSTR-1. This is a common source of ITC disallowance on travel invoices.
OTA invoices with split GST components: Some OTAs issue one invoice with the base fare, a convenience fee, and a dynamic insurance fee — each potentially with different GST treatment. If the accounts team claims ITC on the full invoice total without parsing the GST-applicable components, the claim is often partially wrong.
Missed filing by the supplier: If the airline or agent forgets to file GSTR-1 for a particular month, or files late, the credit will not appear in GSTR-2B in time for your filing cycle. This can create a cash-flow impact — you either delay claiming the credit or claim provisionally and risk scrutiny.

Common ITC disallowance errors on group flight invoices

Based on the GST audit notices that have emerged on travel-expense ITC claims, here are the most frequent errors:

Claiming ITC on 5% domestic economy fares: As explained above, this is often blocked under Section 17(5). If your company has been consistently claiming ITC on domestic economy flight invoices, it is worth reviewing with your CA — this is a common audit focus area.
Employee names on invoices instead of company GSTIN: If the flight ticket is issued in the employee’s name and the GSTIN on the invoice is the employee’s (or absent), the company cannot claim ITC on it. Group flight invoices must show the company’s GSTIN as the recipient. For group bookings, ensure the invoice is issued to the company, not to individual employee names.
Place of supply errors on mixed-city group departures: Groups that depart from multiple cities (some from Mumbai, some from Bangalore on the same trip) may have invoices with different place of supply, affecting whether CGST+SGST or IGST applies and which state’s input credit you can offset against.
Claiming on invoices above two financial years old: ITC claims have a time limit under GST law. If a group travel invoice from a prior year resurfaces late in the reconciliation process, the claim window may have lapsed.

If you’re a travel manager or finance controller for a company that does regular group travel, the safest practice is to run all group flight invoices through a reconciliation with GSTR-2B before claiming ITC, and to have your CA explicitly opine on which GST components are claimable for your specific business category. The cbic.gov.in circulars and the GST Council’s FAQ on travel services are the authoritative starting points.

What the invoice from an airline or OTA should show for a valid ITC claim

For a group flight invoice to support a valid ITC claim (on the claimable components), it should include:

Supplier’s GSTIN: Airline or agent’s registered GSTIN on the invoice header
Recipient’s GSTIN: Your company’s GSTIN — not the individual employee’s name
HSN/SAC code for air transport services (9964 for passenger transport is the relevant SAC)
Clearly split line items: Base fare, airport development fee or user development fee, GST-applicable service fee, GST rate and amount for each component separately
Invoice number and date that can be cross-referenced in GSTR-2B

Many OTA invoices and even some airline invoices do not meet all these criteria as standard output — you may need to specifically request a GST-compliant tax invoice from the supplier, especially for large group bookings. MakeMyTrip, Cleartrip and Ixigo all have a GSTIN input field during booking that generates a proper B2B tax invoice in most cases. IndiGo and Air India’s direct booking portals also support GST invoice generation with your company GSTIN — do not skip this step at booking for any group travel. See also our article on Air India Express group booking portal which walks through where the GSTIN field appears in that flow.

For ongoing corporate group travel management, consider using FlightGPT Partner — the B2B portal lets your travel desk manage bookings with structured invoice outputs and track group PNRs. Also check FlightGPT for route comparisons when planning which carrier to book for your group, as fare levels affect the total invoice size and thus the absolute ITC quantum.

Bottom line

The ITC landscape on group flight invoices is genuinely complex — domestic economy at 5% is largely blocked, agent service fees at 18% are generally claimable, and international fare base is zero-rated with only the agent’s fees in the 18% ITC bucket. The single biggest risk in practice is claiming ITC on components that are blocked or not matched in GSTR-2B. Run a clean GSTR-2B reconciliation before every quarterly filing if your company has significant group travel spend, and get explicit CA sign-off on the treatment. The cbic.gov.in portal, particularly the GST Council FAQs and sector-specific clarification circulars, is the authoritative source for the current rules.

Frequently asked questions

Can a company claim GST input tax credit on domestic economy flight tickets for employee group travel?

Generally, ITC on domestic economy flight tickets (taxed at 5% GST) is blocked for most businesses under Section 17(5) of the CGST Act. Business-class domestic tickets (12% GST) have different ITC eligibility. The current treatment should be confirmed with your CA and cross-checked against the latest CBIC circulars on cbic.gov.in, as interpretations can shift with council decisions.

What GST rate applies to the travel agent’s service fee on international group flight bookings?

An Indian travel agent’s service fee on international flight bookings is typically subject to 18% GST (as a supply of service). The base international fare itself is zero-rated (export of service by the airline). It is the 18% on the agent’s fee that a registered business can typically claim as ITC, subject to GSTR-2B matching.

Why do group flight invoices get flagged in GST audits more than individual ticket invoices?

Group invoices often have higher aggregate values, making them audit targets. Additionally, group bookings more frequently involve sub-agents, split PNRs, or invoices issued in individual employee names rather than the company’s GSTIN — all common sources of ITC disallowance. Always ensure the invoice shows your company GSTIN as the recipient before filing the claim.

What is the GSTR-2B matching requirement for flight ITC claims?

GSTR-2B is your auto-populated ITC register. ITC can only be claimed safely when the supplier (airline or agent) has reported the supply in their GSTR-1 and it appears in your GSTR-2B. If the credit does not appear there — due to the supplier filing late or filing errors — claiming it provisionally in GSTR-3B can attract scrutiny under Rule 36(4). Reconcile GSTR-2B against your invoices before each filing cycle.

What should a GST-compliant group flight invoice include to support an ITC claim?

The invoice must show the supplier’s GSTIN, your company’s GSTIN as the recipient, the correct SAC (9964 for passenger transport services), separate line items for each GST-applicable fee component with the rate and amount, and an invoice number that will appear in your GSTR-2B. Request this explicitly at booking on the airline’s direct site or OTA — most support GSTIN entry during checkout.

Is there a time limit for claiming ITC on flight invoices?

Yes, GST law sets a deadline for claiming ITC — it must be claimed by the earlier of the filing of the annual return for the relevant financial year or 30th November of the following year (as of current rules). Invoices from prior financial years may have their ITC claim window lapsed. Verify the current time limits on cbic.gov.in or with your CA, as amendments have shifted these deadlines in past GST Council meetings.
