Reimbursement at cost is only one part of the test
Rule 33 excludes qualifying pure-agent expenditure from the supplier’s value only where its conditions and definition are satisfied. A separate reimbursement line, a recovery equal to cost or the client’s willingness to pay is not sufficient on its own. Distinguish the supplier’s own service inputs from an additional third-party supply procured as the client’s pure agent.
Read the cumulative requirements
CBIC Circular 115/34/2019-GST dated 11 October 2019 reproduces rule 33’s requirements and applies them in an airline/airport-services context. The supplier must pay the third party as the recipient’s pure agent on the recipient’s authorisation, separately indicate that payment in its invoice, and procure the third-party supply in addition to its own-account services. The definition also requires a contractual agreement, no intended or actual title to the procured supply, no use for the agent’s own interest, and recovery of only the actual procurement amount in addition to the agent’s own service consideration. Sources were checked on 22 October 2026.
The circular’s airport application illustrates the rule; it is not a blanket ruling for every professional reimbursement. For a CA, CS, consultant or other supplier, check the actual engagement and expense documents against each condition. An authority fee paid for a client’s own application may be materially different from the consultant’s hotel, employee travel or software subscription used to deliver the consultant’s work.
Build the evidence before excluding the amount
The engagement should identify the expense the supplier is authorised to incur on the client’s behalf. Retain the actual third-party receipt, the party to whom the supply belongs, the legal liability where relevant, the payment trail and the invoice disclosure. A client-name receipt can support the analysis but does not by itself establish all conditions. Nor can an invoice label correct the absence of the actual agency arrangement.
Keep own service fees and eligible disbursements separate in the working. A genuine separately agreed handling or professional fee can remain taxable as the supplier’s consideration while the exact qualifying third-party payment is analysed for exclusion. Conversely, marking up the procurement recovery can defeat the actual-amount condition for that purported pure-agent recovery; do not exclude the entire marked-up amount or assume that only the markup needs tax without examining the structure.
Own costs are not converted into client supplies by rebilling
Where travel, accommodation, staff cost or another input is used for the supplier’s own work, applying the word reimbursement does not establish pure agency. Determine the actual valuation under the applicable provisions and contract. A service can have an inclusive commercial price or an agreed fee plus own-cost recovery; the tax calculation should reflect the correct taxable value, not merely the supplier’s revenue ledger title.
The examples assume ordinary taxable own-account services at 18%, an assumed applicable rate for those cases. They do not prescribe 18% for every profession, expense or underlying third-party supply. The third party’s GST treatment remains separate. Exclusion from the agent’s supply value does not mean that the underlying supply is tax-free or that the agent can treat the client’s input tax as its own credit. The circular expressly makes this separation in its stated airline example.
Reconcile advances, unused funds and the final invoice
A client may send money before the supplier incurs disbursements. Track receipt, actual authorised payment, eligible amount invoiced and unused balance refunded or still held. The unused balance is not an actual third-party expenditure. Advance timing, adjustments and tax on any own-service component require a separate time-of-supply review; the pure-agent label does not resolve those questions automatically.
Use an expense-by-expense decision column rather than a single yes/no flag for the entire client. A job can include one eligible client fee and several own expenses that do not satisfy rule 33. The invoice must keep the resulting tax base, GST, exact eligible recovery and total payable reproducible. Reconcile the disbursement control account to receipts and refunds so costs cannot be excluded once and also hidden in the taxable fee calculation.
Worked illustrations
The following cases use fictional figures and stated assumptions. Amounts are Indian rupees unless a different unit is expressly shown. They illustrate preparation controls and do not represent real client results.
Illustrative example 1: an exact authorised client fee
Assume professional fee ₹20,000 and an additional client statutory filing fee ₹5,000, with every pure-agent condition demonstrably satisfied for the latter. At the assumed 18% on the professional service, GST is ₹3,600. Invoice total is ₹20,000 + ₹3,600 + ₹5,000 = ₹28,600. The ₹5,000 is excluded on the stated rule conditions, not simply because it is a government fee.
Illustrative example 2: the consultant’s own travel
Professional service fee is ₹20,000 and an agreed recovery of the consultant’s own travel cost is ₹5,000. Assume the travel is used for the consultant’s own performance, pure agency fails, and the correct taxable service value under the stated contract is ₹25,000. At 18%, GST is ₹4,500 and invoice total ₹29,500. Charging tax only on ₹20,000 would omit ₹900 under these facts.
Illustrative example 3: a mixed-expense job
Assume own fee ₹30,000, the supplier’s own job travel recovery ₹3,000, and a separately evidenced ₹7,000 client disbursement satisfying every rule 33 condition. Taxable value is ₹33,000; GST at assumed 18% is ₹5,940. Total payable is ₹33,000 + ₹5,940 + ₹7,000 = ₹45,940. Do not give the entire expense bundle the same treatment.
Illustrative example 4: a separate handling service remains consideration
Assume own fee ₹20,000, a genuinely separate agreed handling-service fee ₹1,000, and exact qualifying client disbursement ₹5,000. Taxable own services total ₹21,000 and GST at assumed 18% is ₹3,780. Total payable is ₹29,780. This assumes the ₹1,000 is a separately identified service fee and does not disguise markup within the claimed actual disbursement.
Illustrative example 5: a marked-up recovery fails the stated structure
A supplier pays ₹10,000 but invoices a single ₹12,000 recovery described as pure-agent cost. Assume that structure fails rule 33 and the full ₹12,000 recovery forms part of an otherwise taxable ₹20,000 service arrangement. Taxable value is ₹32,000; GST at assumed 18% is ₹5,760 and total ₹37,760. Do not automatically exclude ₹10,000 or tax only the ₹2,000 markup without a different supported legal and contractual analysis.
Illustrative example 6: unused client advance is not a disbursement
Assume a separately tracked client disbursement advance ₹15,000. Actual authorised third-party payments satisfying rule 33 total ₹12,400. The unused ₹2,600 is returned: ₹15,000 − ₹12,400 = ₹2,600. Only ₹12,400 is supported as actual disbursement in this reconciliation; the supplier cannot retain and describe all ₹15,000 as an exact recovery. Any own-service advance needs its separate tax analysis.

Sixteen practitioner FAQs
1. Is every at-cost reimbursement excluded?
No. Actual recovery is one requirement; the other rule 33 conditions also need to be met.
2. Does a separate invoice line prove pure agency?
No. Separate disclosure is necessary under the stated rule but is not the complete test.
3. Is a client-name receipt sufficient by itself?
It is evidence of the transaction, but authorisation, agreement, title, own use and actual recovery still need review.
4. Are all statutory filing fees automatically excluded?
No. Establish the supplier’s actual agency role and the client expenditure, then apply all conditions.
5. Can the supplier’s own travel be pure-agent cost just because the client pays?
The own-use condition must be satisfied; rebilling alone does not change the nature of the travel.
6. Can one job contain both eligible and ineligible expenses?
Yes. Assess each expenditure separately and compute the tax base accordingly.
7. Does exclusion mean the third-party supply itself is exempt?
No. Exclusion from the agent’s value and taxation of the underlying supply are separate questions.
8. May the agent use the client’s input tax as its own automatically?
No. Identify the actual recipient and applicable credit conditions; do not duplicate or misattribute credit.
9. Can the agent earn a separate service fee?
Yes, on the stated genuine structure; its own consideration remains separately taxable as applicable.
10. Does a markup preserve exact-cost recovery?
A marked-up procurement recovery can fail the actual-amount requirement. Examine the real arrangement.
11. Can only the markup always be taxed?
No universal rule follows. Determine whether any part actually meets the exclusion conditions.
12. Does Circular 115 decide all professional expense cases?
No. It reproduces the rule and applies it to a particular airport/airline arrangement.
13. Is an unused client advance an actual expenditure?
No. Reconcile it to amounts paid and amounts returned or still held.
14. Does pure agency settle GST time-of-supply questions for advances?
No. Time-of-supply questions, including any own-service advance, require separate analysis.
15. Is 18% mandatory for every amount in these examples?
No. It is an assumed rate for the stated own-account services. Verify the real supply and rate.
16. What is the key invoice check?
The taxable value, GST, exact qualifying disbursements and total payable should reconcile to the contract and payment evidence.

Conclusion
Exclude a client expenditure only after documenting the complete pure-agent relationship. An expense-wise working separates eligible payments from own costs and makes the final tax base, advance balance and invoice total traceable.
