Valuation Rules under GST: Open Market Value, Related-Party Supplies, and Pure Agent Concept
Determining the correct value on which Goods and Services Tax (GST) is levied is one of the most critical aspects of tax compliance under Indian indirect tax laws. While the transaction value forms the default basis of assessment under Section 15(1) of the Central Goods and Services Tax (CGST) Act, 2017, there are numerous legal scenarios where the actual contract price cannot be accepted at face value.
When transactions occur between related parties, when non-monetary consideration is involved, or when a taxpayer acts merely as a intermediary paying expenses on behalf of a client, standard transaction pricing principles fail. In such circumstances, Chapter IV of the CGST Rules, 2017 (Rules 27 to 35) mandates specific valuation mechanisms.
This comprehensive guide delves deep into the statutory framework governing GST valuation rules, exploring Open Market Value (OMV), related-party transactions, Rule-wise determination steps, and the intricacies of the Pure Agent concept.
1. Statutory Foundation of Valuation Under GST
Section 15 of the CGST Act, 2017 Explained
Section 15 forms the core framework for assessing the taxable value of goods or services. It is divided into three primary segments:
Section 15(1) – Transaction Value Basis: The value of a supply of goods or services shall be the transaction value, which is the price actually paid or payable for the said supply, provided two conditions are cumulatively satisfied:
The supplier and the recipient are not related.
The price is the sole consideration for the supply.
Section 15(2) – Mandatory Inclusions in Transaction Value: The value of supply must explicitly include:
Duties, Taxes, and Cess: Any taxes, duties, fees, and charges levied under any law other than CGST, SGST, UTGST, or IGST (e.g., municipal taxes, custom duties).
Third-Party Payments by Recipient: Any amount that the supplier is legally liable to pay, but which has been incurred by the recipient of the supply and not included in the price.
Incidental Expenses: Charges such as packing, commission, freight, inspection, and loading charged by the supplier to the recipient prior to or at the time of delivery.
Interest, Late Fees, or Penalties: Fees levied for delayed payment of consideration for any supply.
Direct Subsidies: Subsidies directly linked to the price (excluding subsidies provided by the Central Government and State Governments).
Section 15(3) – Exclusions of Discounts: Discounts are deductible from the taxable value only if:
Pre-supply discounts: Given on or before the time of supply and recorded on the face of the tax invoice.
Post-supply discounts: Given after supply provided there is a pre-existing agreement established before or at the time of supply, specifically linked to relevant invoices, and Input Tax Credit (ITC) attributable to the discount is reversed by the recipient.
Section 15(4) & Section 15(5) – Mandate for Determination Rules: Where transaction value cannot be accepted under Section 15(1), the valuation must be determined in accordance with Chapter IV of the CGST Rules.
2. Understanding Open Market Value (OMV) under GST
Definition of Open Market Value (Explanation to Chapter IV Rules)
Open Market Value (OMV) of a supply of goods or services means the full amount of money value (plus applicable GST) that the supply would fetch in the open market if sold to an unrelated person where price is the sole consideration.
Key Criteria for OMV Determination:
The transaction must be between unrelated entities.
Money consideration must be the sole factor influencing the transaction.
The supply being evaluated must occur at or around the same time as the benchmark supply.
Distinction Between “Open Market Value” and “Like Kind and Quality”
To apply GST valuation rules correctly, one must differentiate between Open Market Value and Supply of Goods or Services of Like Kind and Quality:
| Parameter | Open Market Value (OMV) | Goods/Services of Like Kind & Quality |
| Primary Definition | Price of identical goods/services sold to unrelated parties in open market conditions. | Price of similar goods/services performing similar functions with closely resembling characteristics. |
| Identity | Identical in all respects (brand, model, quality, reputation). | Substantially similar in nature, quality, quantity, functional utility, and reputation. |
| Applicability Priority | Primary valuation step under Rule 27(a) & Rule 28(1)(a). | Secondary valuation step under Rule 27(b) & Rule 28(1)(b) when OMV is unavailable. |
3. Valuation Rules in Non-Monetary Consideration (Rule 27)
When the consideration for a supply is not wholly in money (e.g., barter systems, exchange offers, trade-ins), Rule 27 of the CGST Rules dictates a strict sequential order of valuation methods.
Sequential Breakdown of Rule 27:
Rule 27(a): Open Market Value: The OMV of such supply.
Rule 27(b): Money Consideration + Monetary Value of Non-Money Element: If OMV is not available, the value is the total of money consideration plus the monetary value equivalent to the non-monetary consideration (if known at the time of supply).
Rule 27(c): Like Kind and Quality: If value cannot be determined under (a) or (b), it is based on the value of supply of goods or services of like kind and quality.
Rule 27(d): Cost/Residual Method: If none of the above work, determination takes place by adding a 10% markup to cost of production/provision (Rule 30) or using reasonable best-judgment principles (Rule 31).
Practical Example: Laptop Exchange Scheme
Scenario: A customer buys a new laptop priced at ₹80,000 in exchange for an old laptop and pays ₹50,000 in cash.
Analysis under Rule 27:
Method 1 (OMV): If the retailer sells the exact same laptop to open-market customers without exchange for ₹80,000, then ₹80,000 is the taxable value under Rule 27(a).
Method 2 (Money + Equivalent Value): If OMV is unavailable, but the old laptop’s market scrap/trade value is established at ₹30,000, then Taxable Value = ₹50,000 (Cash) + ₹30,000 (Monetary Value of Old Laptop) = ₹80,000 under Rule 27(b).
4. Valuation of Related-Party Supplies & Distinct Persons (Rule 28)
Transactions between related entities or distinct entities under GST are scrutinised closely because transfer pricing can easily distort revenue realization.
Definition of Related Persons under GST (Explanation to Section 15)
Persons are deemed to be “related persons” under GST if:
They are officers or directors of one another’s businesses.
They are legally recognized partners in business.
They are employer and employee.
Any person directly or indirectly owns, controls, or holds 25% or more of the voting stock or shares of both of them.
One of them directly or indirectly controls the other.
Both of them are directly or indirectly controlled by a third person.
Together they directly or indirectly control a third person.
They are members of the same family (includes spouse, children, dependent parents, grandparents, brothers, and sisters).
Distinct Persons under Section 25(4) and 25(5)
Establishments of the same legal entity registered under different GSTINs across different States (or multiple GSTINs within a State) are classified as “Distinct Persons”. Stock transfers, branch transfers, or cross-charges between distinct persons constitute a “supply” under Schedule I even if done without consideration.
Valuation Hierarchy under Rule 28
Under Rule 28, the value of supply between related or distinct persons (other than an agent) follows this hierarchy:
Open Market Value (OMV) of such supply.
If OMV is not available, the value of supply of Like Kind and Quality.
If value is not determinable under above clauses, apply Rule 30 (Cost + 10%) or Rule 31 (Residual Value) sequentially.
Provisos to Rule 28: Critical Flexibility Options
Rule 28 provides two very important relief provisions that simplify valuation for corporate groups:
Proviso 1: The 90% Valuation Option for Resale
Where goods are supplied by a supplier to a related recipient who intends to supply the same goods as such (without further processing), the value declared by the supplier can optionally be 90% of the price charged by the recipient to their unrelated customer.
Example: Head Office (HO) supplies a TV to its branch. The branch sells the TV to an unrelated retail customer for ₹1,000,000.
Valuation: The HO can legally value its transfer to the branch at 90% of ₹100,000 = ₹90,000.
Proviso 2: The Full Input Tax Credit (ITC) Safeguard Clause
Statutory Text Interpretation: “Provided further that where the recipient is eligible for full Input Tax Credit, the value declared in the invoice shall be deemed to be the open market value of the goods or services.”
Impact: This proviso acts as a tax neutrality mechanism. If the receiving branch/related party can claim 100% ITC of the GST charged on the transaction, tax revenue to the government remains cost-neutral. Therefore, tax authorities accept whatever value is declared on the invoice—even nominal values like ₹1 or zero—as the valid Open Market Value.
5. Cost-Based Valuation (Rule 30) and Residual Best-Judgment Valuation (Rule 31)
When valuation cannot be established via OMV, Like Kind/Quality, or special options, statutory fallback rules apply.
Rule 30: Value Based on Cost (110% of Cost)
If the value of a supply of goods or services cannot be determined by any preceding rules, the value shall be 108% to 110% (specifically 110%) of the:
Cost of production or manufacture (for goods), OR
Cost of acquisition (for traded goods), OR
Cost of provision (for services).
$$\text{Taxable Value under Rule 30} = \text{Total Cost} \times 1.10$$Rule 31: Residual Method (Best Judgment Valuation)
If valuation cannot be achieved using Rule 30, the value shall be determined using reasonable means consistent with the principles and general provisions of Section 15 and Chapter IV Rules.
Service Flexibility: Suppliers of services are allowed to skip Rule 30 and apply Rule 31 directly after failing Rule 27 or Rule 28.
Data Sources: Best judgment can utilize industry benchmarks, standardized cost tables, independent valuation reports, or historical pricing models.
6. The Pure Agent Concept in GST Valuation (Rule 33)
In corporate, legal, logistical, and custom-clearance operations, service providers frequently incur expenditure on behalf of their clients. Including such pass-through reimbursements in the taxable value of the provider’s service would unfairly inflate tax liability. Rule 33 resolves this by providing the Pure Agent framework.
What is a “Pure Agent”?
A Pure Agent is a person/entity who enters into a contractual agreement with the recipient of supply to incur expenditure or costs in the course of supply, without claiming any title or economic ownership over the underlying goods or services.
Statutory Conditions to Qualify as a Pure Agent (Rule 33)
To exclude reimbursement expenses from the taxable value of service, all four of the following statutory conditions must be cumulatively fulfilled:
Contractual Authorization: The supplier acts as a pure agent of the recipient when they make the payment to the third party based on clear contractual authorization.
No Ownership Rights: The supplier neither intends to hold nor holds any title or interest in the goods or services procured as a pure agent.
No Personal Use: The supplier does not use the goods or services so procured for their own personal/corporate consumption.
Actual Amount Recovery: The supplier receives only the actual amount incurred to procure such goods or services (no markup/margin added).
Conditions for Exclusion from Taxable Value
In addition to qualifying as a Pure Agent, the transaction must meet these operational criteria:
The payment made by the pure agent is separately indicated in the invoice issued to the recipient.
The supplies procured by the pure agent from the third party are in addition to the core services provided on their own account.
Comparative Case Analysis: Pure Agent vs. Compound Service Charge
To avoid tax litigation, businesses must clearly distinguish between pass-through expenses incurred as a Pure Agent and incidental operational expenses incurred while rendering services.
Real-World Example 1: Customs Brokerage Service (Qualifies as Pure Agent)
Facts: A Freight Forwarder/Customs House Agent (CHA) helps an importer clear cargo. The CHA pays ₹50,000 as Customs Duty and Port Charges directly to government authorities on behalf of the importer. The bill issued by the port is in the importer’s name.
Invoice Structure:
CHA Agency/Professional Service Fees: ₹15,000
Reimbursable Port Charges & Customs Duty (as Pure Agent): ₹50,000
Tax Treatment: GST is applicable ONLY on ₹15,000. The ₹50,000 pass-through cost is excluded under Rule 33.
Real-World Example 2: Corporate Travel Agent (Fails Pure Agent Test)
Facts: A travel agency books hotel rooms and airline tickets using its corporate credit account to deliver an all-inclusive event management service. The agency marks up the ticket prices by 10% and invoices a single flat fee without itemizing original third-party bills or getting explicit authorization for separate disbursement.
Tax Treatment: Fails Rule 33 due to markup and absence of separate agency authorization. GST applies on the entire invoiced amount.
7. Special Valuation Rules (Rules 31A, 32, 34, and 35)
The CGST Rules provide dedicated, specialized valuation rules for specific industries and transaction structures:
Summary of Specialized Valuation Provisions
8. Judicial Precedents & Circulars Governing GST Valuation
Tax courts and the Central Board of Indirect Taxes and Customs (CBIC) have repeatedly clarified valuation ambiguities:
CBIC Circular No. 199/11/2023-GST (Head Office – Branch Office Head Office Costs/Cross Charge):
Clarified that in respect of HO-Branch transactions where recipient branch is eligible for full ITC, any value declared on the invoice by HO (including zero value) is acceptable under Proviso 2 to Rule 28.
If HO does not issue an invoice for internally generated administrative services, the value can be deemed as NIL.
M/s Columbia Asia Hospitals Pvt Ltd (AAAR Karnataka):
Held that employee costs incurred at Head Office for management services rendered to distinct branch units must be included in the valuation of cross-charge services under Rule 28, as HO and branches are distinct persons.
Intercontinental Consultants and Technocrats Pvt. Ltd. (Supreme Court Benchmark):
While decided under the erstwhile Service Tax regime, its core principle remains foundational to Rule 33: Tax can only be levied on the consideration for the service provided, not on pass-through expenses incurred purely as an agent without value addition.
9. Comprehensive Compliance Checklist for GST Valuation
To prevent audit flags, demands, and litigation under Section 73/74 of the CGST Act, corporate accounts and tax teams should apply this review checklist:
[ ] Identify Related/Distinct Parties: Check if transactions involve related persons, holdings, subsidiaries, joint ventures, or distinct state registrations under Section 15.
[ ] Verify Full ITC Status: Determine whether the recipient entity is eligible for 100% Input Tax Credit. If yes, leverage Proviso 2 to Rule 28 for valuation flexibility.
[ ] Document OMV Benchmarks: Maintain contemporaneous market price listings, product catalogs, or third-party quotations whenever using Open Market Value under Rule 27 or Rule 28.
[ ] Audit Pure Agent Contracts: Ensure written agency contracts exist before making pass-through payments. Ensure third-party invoices are issued directly in the recipient’s name and billed without markups.
[ ] Check Non-Monetary Consideration: Review barter deals, old-product trade-in schemes, and promotional offers to ensure non-monetary value is calculated into taxable value under Rule 27.
[ ] Review Post-Supply Discounts: Confirm that volume rebates and post-supply discounts comply with Section 15(3)(b) with pre-existing agreements and recipient ITC reversal.
[ ] Validate Rule 30/31 Calculations: For internal cost allocations where recipient ITC is restricted, verify that cost computations accurately include direct overheads plus the mandatory 10% markup.
Conclusion
Understanding GST valuation rules is essential for maintaining tax compliance, preventing litigation, and optimizing tax positions. By systematically evaluating transactions under Section 15, applying Chapter IV CGST Rules sequentially, and properly structuring pass-through costs under the Pure Agent framework, tax managers can ensure robust compliance while avoiding unexpected tax exposure.
