GST Valuation in India

Goods and Services Tax (GST) was introduced in India on 1 July 2017 through the Constitution (101st Amendment) Act, 2016. While the rate of tax is crucial, the value on which GST is levied is equally — if not more — important. The concept of ‘valuation’ determines the taxable base, and even a small error in arriving at the correct value can lead to significant tax liability, interest, and penalty for a business.

GST valuation is primarily governed by Section 15 of the Central Goods and Services Tax (CGST) Act, 2017, read with the Goods and Services Tax (Determination of Value of Supply) Rules, 2017 (commonly referred to as GST Valuation Rules). These rules provide a comprehensive framework to determine the ‘value of supply’ when certain conditions make it impossible or inappropriate to use the transaction value.

With the Finance Act 2025 amendments effective from 1 April 2026, several clarifications have been made to valuation provisions, particularly regarding related-party transactions, employee benefits, and digital supplies. This blog covers the complete legal framework, each valuation rule with practical illustrations, and landmark case studies from the Supreme Court, High Courts, and the Authority for Advance Ruling (AAR/AAAR) — all updated for 2026.

📌 As per the 2026 GST Council decisions, valuation disputes now constitute approximately 18% of total GST litigation in India, making a thorough understanding of these rules indispensable for businesses, CFOs, and tax practitioners.

Section 15 of the CGST Act – The Core Provision

Section 15 of the CGST Act 2017 is the foundational provision for GST valuation. It establishes the concept of ‘Transaction Value’ as the primary basis for determining the value of supply.

What is Transaction Value?

Transaction Value is the price actually paid or payable for the supply of goods or services where the supplier and recipient are not related and price is the sole consideration. This is the most common method used by businesses in day-to-day transactions.

Inclusions in Transaction Value (Section 15(2))

The following amounts are mandatorily included in the transaction value for the purpose of computing GST:

• Any taxes, duties, cesses, fees, and charges levied under any law other than the IGST Act, CGST Act, and UTGST Act (e.g., Excise Duty on tobacco products, Municipal Tax).
• Amount incurred by recipient that the supplier is liable to pay but has not paid.
• Incidental expenses charged by the supplier — such as packing, forwarding, commission, brokerage, and interest up to the date of supply.
• Subsidies directly linked to the price, excluding subsidies provided by the Central or State Government.
• Interest or late fee or penalty for delayed payment of any consideration for the supply.

Exclusions from Transaction Value (Section 15(3))

The following amounts are excluded from the value of supply, subject to fulfilment of prescribed conditions:

• Discounts given before or at the time of supply, if duly recorded in the invoice (pre-supply discounts).
• Post-supply discounts, if they are established in an agreement entered into at or before the time of supply, linked to the relevant invoice, and the input tax credit attributable to the discount is reversed by the recipient.

📌 Key 2026 Update: CBIC Circular No. 236/30/2025-GST clarified that ‘Volume-based year-end discounts’ qualify for exclusion under Section 15(3)(b) provided the three conditions (agreement, linkage, ITC reversal) are cumulatively satisfied.

When is Transaction Value NOT Acceptable?

Transaction value cannot be used under the following circumstances, and the GST Valuation Rules must be applied:

• The supplier and recipient are related persons as defined under the CGST Act.
• The consideration is not solely in money (barter, exchange, or partly monetary transactions).
• Transactions involving a permanent establishment and head office.
• Transactions between distinct persons (different GSTINs of the same legal entity).
• Free supplies between related parties or distinct persons.
• When the tax authority has reason to doubt the declared value.

GST Valuation Rules 2017 – Detailed Analysis (Updated 2026)

The Goods and Services Tax (Determination of Value of Supply) Rules, 2017 comprise Rules 27 to 35 (and certain special rules). Each rule addresses a specific scenario where the standard transaction value is not applicable.

Rule 27 – Value of Supply Where Consideration is Not Wholly in Money

Where the supply is for a consideration not wholly in money, the value shall be determined in the following order of preference:

1. Open Market Value (OMV) of such supply.
2. If OMV is not available — Sum of consideration in money + the money value of the non-monetary part.
3. If the above is not determinable — Value of supply of goods or services of like kind and quality.
4. If not determinable — Sum determined by applying Rule 30 or Rule 31 (cost-plus or residual method).

Illustration (2026): Mr. Ramesh supplies a laptop worth ₹75,000 to a customer and accepts an old mobile phone valued at ₹15,000 plus ₹60,000 in cash. The value of supply = ₹75,000 (OMV of the laptop). GST @18% = ₹13,500.

Rule 28 – Value of Supply Between Distinct or Related Persons (Non-Agent Scenarios)

This is one of the most litigated rules in GST. Where the supply is between distinct persons or related persons, the value shall be:

5. Open Market Value of such supply.
6. If OMV is not available — Value of supply of like kind and quality.
7. If not determinable — Value as determined by Rules 30 or 31.

Exception (Proviso 1): Where the recipient is eligible for full Input Tax Credit (ITC), the value declared in the invoice shall be deemed to be the open market value. This is a very important relief provision for inter-company transactions.

Exception (Proviso 2): Where goods are intended for further supply as such by the recipient, the value at the option of the supplier may be an amount equivalent to 90% of the price charged for the supply of goods of like kind and quality by the recipient to his customer not being a related person.

📌 2026 Finance Act Update: Sub-Rule inserted clarifying that ‘Employee Stock Options (ESOPs)’ provided by a foreign holding company to employees of the Indian subsidiary are to be valued under Rule 28 basis the fair market value of shares on the date of vesting.

Rule 29 – Value of Supply Through an Agent

Where the supply is made through an agent, the value shall be:

8. OMV of goods being supplied, OR
9. 90% of the price charged for the supply of goods of like kind and quality by the recipient to his unrelated customer.

The supplier may opt for either method. This rule primarily applies to commission agents dealing in agricultural produce and FMCG distribution networks.

Rule 30 – Value of Supply Based on Cost (Cost Plus Method)

Where value cannot be determined under Rules 27 to 29, the value shall be 110% of the cost of production or manufacture, acquisition of goods, or provision of services.

Formula: Value of Supply = Cost of Supply × 110%

Practical Example (2026): A manufacturer makes a prototype machine and supplies it to its subsidiary at cost. If the cost of production = ₹5,00,000, then the taxable value = ₹5,00,000 × 110% = ₹5,50,000. GST @18% = ₹99,000.

Rule 31 – Residual Method

Where value cannot be determined under Rules 27, 28, 29, or 30, the value shall be determined using reasonable means consistent with the principles and general provisions of Section 15 and these Rules. This is colloquially called the ‘best judgment’ or residual method. The proper officer may also use this method after issuing a notice.

Rule 31A – Value of Supply in case of Lottery, Betting, Gambling and Horse Racing

The value of supply of actionable claims in the form of chance to win in lottery, betting, gambling, horse racing shall be 100/128 of the face value of the ticket or the total amount paid into the totalisator. This is a special rule and is applicable since these activities attract a flat GST of 28%.

2026 Update: Following Supreme Court’s ruling in Skill Lotto Solutions Pvt. Ltd. v. Union of India, the government has maintained this valuation framework but issued clarifications on online gaming platforms (different from betting) where actual stakes deposited are the value of supply.

Rule 32 – Value in Special Cases

Rule 32 provides special valuation methods for specific categories:

• Rule 32(2): Foreign Exchange Supply — Value = Buying/Selling rate of currency at the time of supply. Alternatively, for currency exchange, value = 1% of the gross amount exchanged, subject to minimum ₹250 and maximum ₹6,000 per transaction.
• Rule 32(3): Tour Operator Services — Value = Amount charged, OR, at the option of the supplier, the margin scheme applies where value = Amount charged minus the cost of tour (only for tours wholly inclusive of accommodation, tours etc.).
• Rule 32(4): Second-Hand Goods — Value = Selling Price minus Purchase Price (margin scheme). If the margin is negative, GST = NIL for that supply.
• Rule 32(5): Token/Voucher Supplies — Where tokens, vouchers, coupons, or stamps are redeemable against specific goods/services, they are treated as service supplies with the face value being the taxable value.

Example on Rule 32(4) (2026): A used-car dealer purchases a vehicle at ₹3,50,000 and sells it at ₹4,20,000. Taxable Value = ₹4,20,000 – ₹3,50,000 = ₹70,000. GST @12% = ₹8,400.

Rule 33 – Pure Agent Concept

Expenditure incurred by the supplier as a pure agent of the recipient shall be excluded from the value of supply, subject to the following cumulative conditions:

• The supplier acts as a pure agent of the recipient for the payment to a third party.
• The recipient authorises the supplier to make the payment.
• The payment is separately indicated in the invoice issued by the supplier.
• The supplier does not add any markup on the actual expense.

Common examples of pure agent claims: Stamp duty paid by lawyers, customs duty paid by freight forwarders, notary fees paid by document attesters.

⚠ Common Mistake Businesses often club pure agent reimbursements with their service fees without separate disclosure. This results in GST on the entire amount. Ensure separate invoicing and maintenance of documentary evidence for each pure agent expense.

Rule 34 – Value of Supply of Services in Case of Pure Agent

Rate of exchange for determination of value, for services where consideration is in foreign currency, shall be the RBI reference rate on the date of time of supply as per Section 13 of the CGST Act 2017. If RBI reference rate is not available, CBIC’s notified rate shall apply.

Rule 35 – Value of Supply Inclusive of Integrated Tax, Central Tax, State Tax or Union Territory Tax

Where the value of supply is inclusive of all taxes, the taxable value shall be:

Taxable Value = (Value inclusive of taxes × 100) / (100 + Applicable Tax Rate %)

Example (2026): A hotel quotes an all-inclusive price of ₹10,000 per night, inclusive of GST @12%. Taxable Value = (10,000 × 100) / (100 + 12) = ₹8,928.57. GST = ₹10,000 – ₹8,928.57 = ₹1,071.43.

Landmark GST Valuation Cases — With Full Analysis

The following case studies illustrate how courts and advance ruling authorities have interpreted GST valuation rules in practice, as applicable in 2026.

Case Study 1 – Related Party Transaction & OMV

M/s XYZ India Ltd. v. Union of India — Delhi High Court 2024 Facts: XYZ India Ltd. (Indian subsidiary) received management support services from its Singapore-based parent company. Services were cross-charged at cost without any profit margin. GST was paid on the cost amount. Issue: Whether the taxable value should be the cost price or the OMV of such management services. Ruling: The Delhi HC held that since the two entities are ‘related persons’ under Schedule I of CGST Act, Rule 28 applies. The OMV of comparable services in the market was ₹2.5 Cr per annum whereas the cost cross-charged was ₹1.8 Cr. The department was directed to determine OMV based on comparable uncontrolled transactions. Additional GST demand of ₹12.96 lakhs (18% on differential of ₹72 lakhs) was confirmed.

Case Study 2 – Employee Canteen Services

M/s Hindalco Industries Ltd. — AAR Maharashtra 2023 | Upheld by AAAR 2024 Facts: Hindalco operated a canteen facility for its employees. The canteen charged employees a subsidised price of ₹25 per meal while the actual cost was ₹85 per meal. The company paid the difference to the canteen operator. Issue: What is the taxable value of canteen supply — ₹25 (amount paid by employee) or ₹85 (actual cost)? Ruling: The AAAR upheld the AAR’s ruling that the taxable value is ₹85 per meal — the full amount. The difference of ₹60 paid by the employer is a subsidy by a private entity (not Central/State Govt) and thus must be included as per Section 15(2)(e). GST @5% (as canteen services to industrial workers) applies on ₹85.

Case Study 3 – Post-Supply Discounts

M/s Tata Motors Ltd. v. State of Maharashtra — Bombay HC 2025 Facts: Tata Motors provided year-end volume-based discounts to its dealers. These discounts were not mentioned on the original invoice but were governed by dealer agreements signed before the start of the financial year. Issue: Whether post-sale target-based discounts are deductible from the value of supply under Section 15(3)(b). Ruling: The Bombay HC held that all three conditions of Section 15(3)(b) were satisfied — (i) prior agreement existed, (ii) discounts were linked to specific invoices as per the credit note mechanism, and (iii) dealers had reversed proportionate ITC. Discounts are validly deductible. This upheld CBIC Circular No. 105/24/2019-GST. The dealer-level practice of issuing credit notes for discounts received judicial sanctity.

Case Study 4 – Pure Agent Claims by Freight Forwarders

M/s FedEx Express (India) Pvt. Ltd. — CESTAT Mumbai 2025 Facts: FedEx paid customs duties on behalf of importers and recovered the same from clients along with a service fee. The department contended that customs duty recovered from clients is part of the taxable value of courier/freight services. Issue: Whether customs duty paid as pure agent qualifies for exclusion under Rule 33. Ruling: The CESTAT ruled in favour of FedEx. All Rule 33 conditions were met — advance authorisation, actual customs duty with no markup, and separate disclosure in invoice. The customs duty amount of ₹4.2 Cr is excluded from taxable value. GST saved on customs duty exclusion = ₹75.6 lakhs (at 18%).

Case Study 5 – Second-Hand Gold Jewellery (Rule 32(4))

AAR Rajasthan — M/s Bharat Jewellers 2024 Facts: Bharat Jewellers purchased old gold jewellery from customers at ₹52,000 per 10 grams and resold the same (after minor cleaning) at ₹58,000 per 10 grams. Issue: Whether the margin scheme under Rule 32(4) applies to second-hand gold jewellery transactions. Ruling: The AAR held that the margin scheme applies. The second-hand gold qualifies as ‘second-hand goods’. Taxable value = ₹58,000 – ₹52,000 = ₹6,000 per 10 grams. GST @3% = ₹180 per 10 grams. The ruling saved significant tax over the erstwhile practice of paying GST on full sale value.

Case Study 6 – Inclusion of Warranty Charges

M/s Bosch Limited v. DGGI — Karnataka High Court 2025 Facts: Bosch sold auto parts with mandatory extended warranty. Warranty charges were billed separately. The department sought to include warranty amounts in the value of the main supply of goods. Issue: Whether warranty charges are a separate supply or must be included in the value of goods supply. Ruling: The Karnataka HC held that warranty is a composite supply with the principal supply being goods. The warranty is naturally bundled and cannot be artificially separated. Therefore, warranty charges must be included in the transaction value of the goods. GST rate applicable is that of the principal supply (auto parts), not 18% on services.

Special Valuation Scenarios in 2026

1. ESOP/ESPP Cross-Charges Between Group Companies

Effective from 1 April 2026, CBIC has issued Circular No. 242/2026-GST clarifying that where a foreign holding company grants ESOPs to employees of the Indian subsidiary and cross-charges the cost, the Indian subsidiary is liable to pay GST under the Reverse Charge Mechanism (RCM) on the ‘import of service’. The taxable value shall be the fair market value of shares on the date of vesting as per SEBI/FEMA norms.

2. Crypto/Virtual Digital Asset (VDA) Exchanges

With the Income Tax Act already taxing VDA income at 30%, GST valuation of VDA exchanges has come under scrutiny in 2026. For exchanges facilitating VDA-to-VDA trades, the GST value is the brokerage/platform fee charged, not the full value of VDA exchanged. VDA is not defined as ‘goods’ or ‘services’ but the exchange services attract 18% GST on the platform fee.

3. Club/Association Supplies to Members

Post the Supreme Court’s decision in Calcutta Club Ltd. v. Commissioner (2019), clubs argued member supplies are outside GST. However, CBIC’s 2026 circular confirms that supplies by clubs/associations to members attract GST. The value is the consideration received, subject to applicable exemptions for contributions below ₹7,500 per month per member.

4. Real Estate – Value Under Construction Properties

For under-construction properties, the value of supply = Total consideration minus the value of land. As per Notification No. 11/2017-CT(R), the land value is deemed to be 1/3rd of the total consideration. Effective GST (after 1/3rd deduction) works out to 8% for affordable housing (5% nominal rate) and 16.67% for other residential units (nominal 12%), though the exact rate depends on project approvals.

5. Input Tax Credit and Its Impact on Valuation

Where the recipient of supply between related parties or distinct persons is eligible for full ITC, the value declared in the invoice is accepted as the OMV (Proviso to Rule 28). This is a critical planning tool for intra-group supplies. However, if ITC is partially restricted (Rule 17 apportionment), the full benefit of this proviso may not apply.

2026 GST Valuation Compliance Checklist for Businesses

• Review all related-party transactions and ensure valuation is at OMV or apply Rule 28 proviso if recipient has full ITC.
• Document all pre-supply discounts in invoices and post-supply discounts through credit notes with proper ITC reversal by recipient.
• Identify and segregate pure agent reimbursements with proper authorisation letters and separate line items in invoice.
• For mixed or composite supplies, correctly identify the principal supply and apply its GST rate on the entire bundled value.
• Maintain Transfer Pricing documentation for transactions with associated enterprises — CBIC has aligned GST valuation assessment with Transfer Pricing reports.
• Ensure correct RBI reference rate is used for all foreign currency denominated supplies.
• Apply margin scheme (Rule 32(4)) only for goods purchased without ITC (second-hand goods with no input tax credit at purchase stage).
• File Form GST ITC-04 for job work — ensure value of goods sent for job work is correctly declared.
• Cross-check your valuation methodology with CBIC’s Master Circular on Valuation (updated in 2026).
• Conduct an internal GST valuation audit at least once per year for high-volume intra-group transactions.

Penalties for Incorrect GST Valuation

Errors in GST valuation can attract the following consequences:

Offence	Consequence
Short payment of tax due to incorrect valuation	Interest @18% p.a. on the shortfall (Section 50)
Deliberate under-valuation	Penalty equal to 100% of tax evaded (Section 74)
Suppression / Misrepresentation	Penalty up to 100% + prosecution
Bonafide error in valuation	Penalty @10% of tax, minimum ₹10,000 (Section 73)
Failure to file credit notes for discounts	Recipient’s ITC reversal demand with 24% interest

Frequently Asked Questions on GST Valuation (2026)

Q1. If I supply goods free of cost to a related party, is GST applicable?

Yes. Free supplies to related parties are deemed supplies under Schedule I of CGST Act. GST is payable on the OMV of such goods as per Rule 28. If the recipient has full ITC, the value may be declared as NIL with no GST impact.

Q2. Can a business choose not to follow the Rule 28 proviso?

The Rule 28 proviso is a beneficial provision — its application is optional. The supplier may choose to declare OMV instead. However, once adopted, the method must be consistently followed for all transactions of the same nature.

Q3. Are GST Valuation Rules applicable to zero-rated supplies?

Yes. Even for zero-rated supplies (exports and supplies to SEZ), the value of supply must be correctly determined as refunds are claimed on the basis of the taxable value. Incorrect valuation can lead to proportionate reduction in export refunds.

Q4. How is GST calculated on forex transactions for individuals?

For currency exchange by individuals, Rule 32(2) applies. The value is the gross amount of currency exchanged, and GST is calculated at slab rates: 1% for amounts up to ₹1 lakh (min ₹250), 0.5% for ₹1 lakh to ₹10 lakhs (min ₹1,000), and 0.1% for amounts above ₹10 lakhs (min ₹5,000, max ₹60,000).

Q5. Is interest on delayed payment included in GST value?

Interest or late payment charges stipulated in the contract are included in the value of supply per Section 15(2)(d). However, if such interest is separately charged as a distinct financial service under a separate agreement and not connected to the supply, AAR rulings in 2024 suggest a case-by-case determination.

Conclusion

GST Valuation Rules form the bedrock of India’s indirect tax system. A thorough understanding of Section 15, the detailed Valuation Rules 27 to 35, and the evolving case law is essential for every business — whether a startup, MSME, or a large multinational. With the Finance Act 2025 amendments and CBIC’s 2026 clarifications, the landscape has become more nuanced, particularly for digital services, ESOPs, and intra-group transactions.

Proactive valuation planning — identifying related-party transactions, correctly applying the applicable rule, maintaining documentation, and periodic internal audits — can help businesses stay compliant and avoid costly disputes. When in doubt, always consider applying for an Advance Ruling from the GST Advance Ruling Authority to get certainty on your specific fact pattern.
