In the GST regime, the taxability of reimbursed expenses hinges on one pivotal question: Are you acting as a “Pure Agent” or is the expense an “Incidental Cost” of your service?
1. The Legal Framework
The core of this issue lies in the valuation of supply.
- Section 15(2)(c) of the CGST Act: States that the value of supply includes incidental expenses (like packing, commission, or travel) charged by the supplier to the recipient.
- Section 15(2)(b) of the CGST Act: Any amount the supplier is liable to pay but which has been incurred by the recipient must be included in the value.
- Rule 33 of the CGST Rules: This is the “safe harbor” rule. It provides that costs incurred as a Pure Agent shall be excluded from the value of supply.
2. When is Reimbursement Taxable? (Incidental Expenses)
If an expense is incurred by the service provider to enable them to perform their main service, it is considered an “incidental expense.”
- Tax Treatment: It must be added to the taxable value of the invoice and GST must be charged at the rate applicable to the main service. The Reimbursement of expenses may be claimed through a separate invoice or may be addded as a separate line item in the main invoice. In either case it is taxable.
- Common Examples: * Travel and hotel stay of a Consultant/CA to a client’s site.
- Postage and courier charges incurred during the delivery of a service.
- Telephone or internet costs.
3. When is Reimbursement Non-Taxable? (The Pure Agent Concept)
Under Rule 33, for an expense to be non-taxable, you must qualify as a “Pure Agent.” This means you are merely a pass-through for the payment.
The 4 Essential Conditions to be a Pure Agent:
- Contractual Agreement: You have a written agreement to act as a pure agent to incur costs.
- No Title/Interest: You do not hold (and don’t intend to hold) any title to the goods/services procured.
- No Personal Use: You do not use the goods/services for your own interest.
- Actual Receipt: You receive only the actual amount incurred—no markup or “handling fees.”
The 3 Conditions for Exclusion from Value:
- The payment is made to a third party on the authorization of the recipient.
- The payment is separately indicated in the invoice.
- The supplies are in addition to the services provided on your own account.
Pro-Tip for the Post: Mention that the Third-Party Invoice should ideally be in the name of the Client (Recipient), but the payment is made by you.
4. Important Recent Clarifications
- Electricity Charges: The CBIC via Circular No. 206/18/2023-GST clarified that where a landlord is acting as a pure agent for the tenant in respect of electricity charges (paying the DISCOM and recovering it from the tenant at actuals), such charges are excluded from the value of rent.
Conclusion
To avoid litigation, professionals and businesses must ensure that “Pure Agent” arrangements are backed by clear engagement letters and separate line items in invoices. Failing to meet even one condition of Rule 33 can lead to the entire reimbursement being treated as a taxable supply.
