Direct answer: Under the optional deemed-valuation mechanism in CGST Rule 32(3), an air travel agent’s ticket-booking service is valued at 5% of basic fare for domestic bookings and 10% for international bookings. Those percentages determine service value; they are not GST rates on the airline ticket. The rule defines basic fare by the portion on which airlines normally pay commission to the agent.
Position checked on 22 October 2026 using ICAI’s April 2026 compilation of the CGST Rules, Rule 32(1) and (3). This article covers the agent’s booking-service valuation. It does not determine the airline’s passenger-transport tax, the agent’s tax rate or place of supply, cancellation adjustments, or the treatment of every additional incentive or customer fee.
Identify the service and the agent’s valuation method
Start by separating the airline’s ticket supply from the agent’s booking service and any distinct services charged by the agent. A customer’s total payment can contain the ticket amount, airport or statutory charges and service fees. It is not automatically the agent’s booking-service taxable value under the deemed method.
Rule 32(1) provides the supplier option for the specified valuation mechanism. Document the basis used and the actual service being valued. Do not import the financial-year non-withdrawal language expressly found in the money-changing limb of Rule 32(2) as if it were text of the air-agent limb. Equally, do not treat the option as permission to omit supplies or change a method without a documented legal and reconciliation review.
Build basic fare from airline evidence
The statutory definition matters more than a customer-facing label. Retain the airline’s fare breakup and evidence identifying the part on which commission is normally paid. A component called surcharge is not automatically included or excluded solely by its name. The examples expressly state which components qualify; those facts must be verified for a real booking.
Actual commission received on one discounted or promotional booking is not necessarily the statutory basic fare. Avoid solving backwards from that commission and a guessed commission rate. Keep the ticket identifier, domestic/international classification, currency, qualifying basic fare and evidence together so the calculation can be reproduced.
Use separate domestic and international subtotals
| Booking category | Verified qualifying basic fare | Deemed booking-service value |
|---|---|---|
| Domestic | Domestic basic fare subtotal | 5% of that subtotal |
| International | International basic fare subtotal | 10% of that subtotal |
| Mixed batch | Keep the two subtotals separate | 5% of domestic plus 10% of international |
Classify the booking from the underlying itinerary and applicable transaction facts rather than from the customer’s address or the airline’s brand name. A mixed desk or monthly settlement needs both categories, not a blanket rate applied to all ticket collections. Where a multi-sector or unusual itinerary needs a classification conclusion, document it before applying the percentage.
Then carry the computed service value to a separate GST review. The value may be smaller than ticket collections and different from the commercial commission. These are not reasons to apply the valuation percentage twice. Determining the actual GST payable requires the applicable rate, exemption, place-of-supply and invoice analysis after valuation.
Other fees and adjustments remain separate review items
A separately charged convenience, advisory or customer-handling service should be identified and assessed rather than silently disappearing inside a deemed booking value. The same applies to airline incentives and other settlement lines: reconcile what each payment relates to and avoid a universal assumption that all amounts are either automatically covered or automatically additional.
Ticket cancellation, reissue and later fare correction also need a dated evidence trail and any applicable invoice or credit-note analysis. A reduced airline settlement does not by itself authorise an arbitrary negative booking-service value in the current return. Resolve the original booking and adjustment documents without duplicating the supply.
The six examples compute only deemed booking-service value, not actual GST. They assume the supplier uses the relevant optional mechanism, the domestic/international classification is established and the qualifying basic fare has been verified. Gross ticket amounts are illustrative collection figures, not airline tax computations.
Worked illustrations
These illustrations use fictional facts and expressly stated assumptions. Amounts are Indian rupees unless a different currency or unit is specified. They are independent examples, not findings about any actual client.
Illustrative example 1: Domestic basic fare differs from gross ticket collection
A domestic ticket has qualifying basic fare of ₹20,000 and total customer ticket collection of ₹26,000. Deemed agent booking-service value is ₹20,000 × 5% = ₹1,000. Applying 5% to the ₹26,000 collection would give ₹1,300 and overstate that value by ₹300.
Illustrative example 2: International booking uses the international fraction
An international ticket has qualifying basic fare of ₹80,000 and gross ticket collection of ₹1,10,000. Deemed agent service value is ₹80,000 × 10% = ₹8,000. The ₹8,000 is not the actual GST charge and does not determine the airline’s passenger-transport liability.
Illustrative example 3: A mixed monthly booking desk
Verified basic fares in a batch are ₹1,50,000 domestic and ₹2,50,000 international. Domestic service value is ₹7,500 and international service value ₹25,000. Total deemed booking-service value is ₹32,500. Keep the two calculations visible instead of applying a single percentage to the ₹4,00,000 combined basic-fare amount.
Illustrative example 4: Identify commission-bearing components rather than guessing
A domestic booking comprises ₹40,000 qualifying basic fare, ₹15,000 of another fare component and ₹5,000 of other ticket charges. Airline evidence establishes that only the ₹40,000 is the relevant commission-bearing portion on these facts. Deemed service value is ₹2,000. Applying 5% to all ₹60,000 would give ₹3,000, overstating value by ₹1,000. This is not a blanket rule about every surcharge.
Illustrative example 5: Group tickets and actual commission are separate records
Five domestic tickets each have ₹12,000 qualifying basic fare. Aggregate basic fare is ₹60,000 and deemed booking-service value ₹3,000. The actual commercial commission happens to be ₹2,000. Under the assumed deemed method, do not replace ₹3,000 with that ₹2,000 settlement line or treat the ₹1,000 difference as an arithmetic error.
Illustrative example 6: Find an international-booking classification error
A register contains ₹2,00,000 domestic and ₹1,00,000 international qualifying basic fares. Correct value is ₹10,000 + ₹10,000 = ₹20,000. A system that marks all ₹3,00,000 domestic calculates ₹15,000, understating value by ₹5,000. Correct the source classification and preserve the adjustment trail; review any reporting correction separately.

Sixteen practitioner FAQs
1. Is 5% the GST rate on every domestic flight ticket?
No. Rule 32(3)’s 5% is a fraction used to value the agent’s booking service under the deemed mechanism.
2. What is the international valuation fraction?
Ten per cent of the qualifying basic fare under the stated mechanism.
3. Does gross customer collection equal basic fare?
Not automatically. Verify the airline’s commission-bearing portion within the statutory definition.
4. Is the label basic on a ticket conclusive?
Retain supporting airline evidence of the part on which commission is normally paid; a label alone may not resolve the statutory test.
5. Are fuel surcharges always excluded?
Do not make a blanket assumption. Check whether the actual component forms part of the relevant commission-bearing fare.
6. Is actual commission itself the deemed service value?
Not under the stated calculation. Apply the fraction to verified basic fare and reconcile commercial commission separately.
7. Can the agent use one fraction for a mixed booking batch?
Keep domestic and international basic-fare subtotals separate before calculating the total value.
8. Does the airline’s brand determine whether a booking is international?
Do not classify solely by brand. Use the underlying itinerary and relevant transaction facts.
9. Does the customer’s residence determine the Rule 32 category?
Not by itself. Classification and the separate place-of-supply analysis require their own facts.
10. Does this valuation settle the airline’s tax liability?
No. The agent’s booking service and the airline’s passenger-transport supply are distinct analyses.
11. Are separately charged customer services automatically omitted?
No. Identify the actual service and analyse its treatment rather than assuming the booking valuation covers every charge.
12. Are all airline incentives automatically additional taxable value?
Avoid a universal conclusion. Determine what the payment relates to and reconcile it with the supplies already valued.
13. Can a cancellation be posted as any chosen negative value?
No. Retain the underlying booking and adjustment documents and assess applicable correction requirements.
14. Does the money-changing annual option restriction automatically govern air agents?
Do not import the specific clause (2) wording into clause (3). Document the actual applicable valuation provision.
15. Do the examples calculate GST payable?
No. They calculate deemed service value; the applicable tax rate and other GST conditions require separate review.
16. Which register fields best prevent errors?
Ticket identifier, category, verified basic fare, source evidence, computed service value and links to settlements and adjustments.
