Time, Place and Value of Supply

Introduction

GST is fundamentally a tax on supplies. A transaction can be taxed correctly only when three questions are answered:

  1. When does the liability arise?
  2. Where is the supply treated as occurring, and which authority is relevant?
  3. What value is taxable?

These questions are governed principally by the Central Goods and Services Tax Act, 2017 (CGST Act), the Integrated Goods and Services Tax Act, 2017 (IGST Act), the corresponding State or Union Territory GST laws, rules, notifications and judicial interpretation. This chapter explains the general statutory framework. Since GST law is frequently amended, professional practice requires checking the law applicable on the relevant date.

Learning Objectives

After completing this chapter, the learner should be able to:

  • determine the time of supply of goods and services;
  • explain the treatment of advances, vouchers, reverse charge and continuous supplies;
  • identify the place of supply for domestic, imported, exported and cross-border transactions;
  • distinguish intra-State and inter-State supplies;
  • compute taxable value, including taxes, incidental expenses, subsidies, discounts and reimbursements;
  • apply valuation rules to related parties, agents, branches and pure agents;
  • analyse digital and remote services; and
  • maintain an auditable record of tax decisions.

1. The Three-Dimensional GST Analysis

A tax invoice is not by itself a complete tax analysis. A professional should establish the following sequence:

QuestionMain issuePrincipal provisions
What is supplied?Goods, services, composite or mixed supplyCGST Act sections 7–8
When?Time of supply and tax periodCGST Act sections 12–14
Where?Place of supply and nature of taxIGST Act sections 7–13
At what amount?Value of taxable supplyCGST Act section 15 and valuation rules

The place of supply does not generally determine whether an activity is a supply; it determines the jurisdictional character and whether CGST plus SGST/UTGST or IGST is payable.

2. Time of Supply of Goods

2.1 Forward-charge supplies

For goods supplied on a forward-charge basis, the general time of supply is the earliest of:

  • the date of issue of invoice, or the last date on which the supplier is required to issue it; and
  • the date on which payment is received.

For this purpose, payment is generally the earlier of entry in the supplier’s books or credit to the supplier’s bank account. Special rules apply where the supplier receives an amount up to ₹1,000 in excess of the invoice amount; the excess may be assigned to the date of invoice at the supplier’s option.

A major practical distinction is that, for ordinary supplies of goods, receipt of an advance does not ordinarily trigger tax liability because the relevant exemption has removed the advance requirement for such goods. The invoice and statutory time-of-supply provisions must nevertheless be checked, particularly for special categories and notified supplies.

2.2 Reverse charge for goods

For goods taxable under reverse charge, the time of supply is determined under the special statutory rule, generally linked to the earliest of:

  • receipt of goods;
  • the date of payment, as determined by the law; or
  • the date immediately following the prescribed period from the date of the supplier’s invoice.

Because reverse-charge notifications and statutory amendments affect the precise rule, the recipient should verify the current provision for the specific notified supply.

2.3 Vouchers

For a voucher, the time of supply is the date of issue if the supply is identifiable at that point; otherwise, it is the date of redemption. For example, a voucher redeemable only for a specified restaurant meal may be taxed at issue, whereas a general-purpose voucher may be taxed at redemption, depending on the legal character and facts.

2.4 Residual rule

Where the time of supply cannot be determined under the principal rules, the residual provision applies. In practice, this may refer to the date of entry in the recipient’s books or the date of payment, as prescribed.

3. Time of Supply of Services

3.1 Forward charge

For services supplied on forward charge, the time of supply is generally:

  • if the invoice is issued within the prescribed period: the earlier of invoice date or payment date;
  • if the invoice is not issued within that period: the earlier of completion of service or payment date; and
  • where neither rule determines the time: the date on which the recipient records the service in its books.

The statutory invoice period differs according to the applicable category of supplier and service. The supplier must therefore connect the invoicing system with actual completion and payment events.

3.2 Advances for services

An advance received for a taxable service generally creates a tax liability to the extent prescribed by the time-of-supply rules. For example, if a consultancy firm receives ₹118,000 as an advance inclusive of GST at 18%, the taxable value is:

Taxable value = 118,000 ÷ 1.18 = ₹100,000

GST is ₹18,000, subject to the applicable legal conditions. The assumption is that the entire advance relates to the taxable service and the rate is 18%.

3.3 Continuous supply of services

A continuous supply involves periodic or recurrent services supplied under a contract for more than the statutory period or where payment obligations are periodic. The time of supply depends on the contractually determinable due date, the invoice date where the due date is not determinable, or the payment date where neither is determinable. If payment is linked to completion of an event, liability arises when that event occurs.

Examples include annual maintenance contracts, leased equipment support and recurring professional retainers.

3.4 Reverse charge for services

For services taxable under reverse charge, the recipient must apply the special rule, commonly based on the earliest of:

  • payment date;
  • the date immediately following the prescribed period from the supplier’s invoice; or
  • the date of entry in the recipient’s books, where applicable.

This is important for imported services and domestic notified services. A recipient should not wait indefinitely for a supplier’s invoice before examining reverse-charge liability.

3.5 Change in rate of tax

When the rate changes between supply, invoice and payment, section 14-type rules determine the applicable rate by examining the timing of the supply, invoice and payment. A tax professional should prepare a three-date matrix rather than applying the new rate automatically.

4. Place of Supply and Jurisdiction

4.1 Intra-State and inter-State supplies

A supply is broadly inter-State when the location of the supplier and the place of supply are in different States, different Union Territories, or one is in a State and the other in a Union Territory. Imports and exports are treated under the IGST framework. Intra-State supplies generally attract CGST and SGST/UTGST.

The supplier’s registration location is not always the place of supply. The statutory rule applicable to the transaction must be applied.

4.2 Goods: movement involved

Where the supply involves movement of goods, the place of supply is generally the location where movement terminates for delivery to the recipient. It is not necessarily the location from which the goods are dispatched.

Where goods are supplied without movement, the place of supply is the location of the goods at the time of delivery. For goods assembled or installed at site, it is the place of installation or assembly.

Goods supplied on board a conveyance, such as an aircraft or vessel, are generally located at the place where they are taken on board.

4.3 Bill-to and ship-to transactions

In a bill-to/ship-to arrangement, the principal supplier directs delivery to a third party. The statutory place-of-supply rule attributes the supply to the principal recipient’s location in the prescribed manner. Documentation should clearly identify the contractual parties, delivery instruction and movement trail.

4.4 Imported and exported goods

The place of supply of imported goods is the location of the importer; for exported goods, it is the location outside India. Customs valuation and IGST at import are separate but connected compliance areas.

4.5 Services supplied to a registered person

For services supplied to a registered person, the place of supply is generally the location of that person. The supplier should obtain and validate the recipient’s GSTIN rather than relying only on an address in a purchase order.

4.6 Services supplied to an unregistered person

For services supplied to an unregistered person, the place of supply is generally the recipient’s location when the address is available; otherwise, it is the supplier’s location, subject to specific rules.

4.7 Specific service rules

Specific place-of-supply provisions override the general rules for services such as:

  • services relating to immovable property: location of the property;
  • restaurant, catering, personal grooming, fitness and similar services: location where performed;
  • training and performance appraisal: recipient’s location for registered recipients and place of performance in specified cases for others;
  • admission to events: place where the event is held;
  • organisation of events: recipient’s location for registered recipients and event location in specified cases for others;
  • transportation of goods: recipient’s location for registered recipients and prescribed location for others; and
  • passenger transportation: prescribed embarkation or recipient-based rules.

4.8 Cross-border digital services

Online information and database access or retrieval services (OIDAR) include electronically supplied services such as online databases, cloud-based digital content and automated software access. The location of an unregistered recipient must be established through prescribed indicators, such as billing address, internet protocol address, bank details, SIM-card country or other reliable evidence.

A non-resident OIDAR supplier supplying non-taxable online recipients in India may have registration and compliance obligations. A human-intensive consultancy delivered by video conference is not automatically OIDAR merely because technology is used; classification depends on the statutory nature of the service.

4.9 Export of services

A service qualifies as an export only when the statutory conditions are satisfied, including supplier location outside India, recipient location outside India, place of supply outside India, receipt of payment in permitted foreign exchange or Indian rupees where allowed, and parties not being merely establishments of the same person. Export treatment should not be assumed from the fact that the customer pays from a foreign bank account.

5. Value of Supply

5.1 Transaction value

Where the supplier and recipient are not related and price is the sole consideration, the taxable value is normally the transaction value: the price actually paid or payable for the supply.

The value includes amounts the supplier is liable to pay but which are incurred by the recipient and not included in the price, as well as incidental expenses such as commission, packing and amounts charged for activities performed before delivery. Interest, late fee or penalty for delayed payment is included in value when actually received.

Government subsidies directly linked to price, other than subsidies provided by the Central or State Governments, are included.

5.2 Taxes and excluded items

GST itself is excluded from taxable value when charged separately. However, other taxes, duties, cesses and fees imposed under laws other than GST may be included if charged separately by the supplier.

A deposit is not consideration unless the supplier applies it as payment for the supply. This distinction prevents every refundable security deposit from being taxed merely because money has changed hands.

5.3 Discounts

A discount shown on the invoice at or before the time of supply is excluded from value. A post-supply discount is excluded only when:

  • it is established under an agreement entered into at or before the time of supply;
  • it is specifically linked to relevant invoices; and
  • the recipient reverses the related input tax credit.

A commercial credit note does not automatically reduce GST liability. The statutory conditions and recipient’s credit reversal must be documented.

5.4 Related persons and distinct persons

Valuation rules apply where parties are related, supplies occur between distinct persons, or price is not the sole consideration. Related persons include, among others, officers or directors of one another’s businesses, legally recognised partners, employer and employee, persons controlling or controlled by one another, and persons under common control.

Branches, establishments and registrations of the same legal entity in different States are distinct persons. The absence of a conventional sale price does not mean that the transaction has no GST value.

The valuation rules generally proceed through:

  1. open market value;
  2. value of like kind and quality;
  3. cost-based value, commonly cost plus 10%; or
  4. a reasonable method consistent with GST principles.

For certain services, the supplier may use 90% of the price charged by the recipient to an unrelated customer for like services, where the prescribed conditions are met. Recipient eligibility for full input tax credit can also affect valuation options under the rules, but it does not eliminate the need for records.

5.5 Pure agent and reimbursements

A reimbursement is not automatically excluded from value. An amount paid by a supplier on behalf of the recipient may be excluded when the supplier acts as a pure agent, including conditions that the supplier:

  • has a contractual arrangement to act as pure agent;
  • does not hold or intend to hold title to the goods or services procured;
  • does not use them for its own interest; and
  • recovers only the actual amount from the recipient.

The third-party supply must also be separately indicated in the invoice and the recipient must be liable to pay the third party. For example, a lawyer recovering a court fee paid in the client’s name may qualify, but a courier or travel expense incurred for the lawyer’s own performance may be part of the taxable value.

5.6 Exchange rates

Foreign-currency transactions require conversion using the notified accounting or customs method applicable to the transaction and date. The invoice, books and return should be consistent, and the chosen rate should be supported by records.

5.7 Valuation formula for tax-inclusive amounts

If a price is inclusive of GST, the taxable value is calculated as:

Taxable value = Tax-inclusive amount × 100 ÷ (100 + GST rate in percent)

For a tax-inclusive price of ₹236,000 at 18%:

Taxable value = 236,000 × 100 ÷ 118 = ₹200,000
GST = ₹36,000

The formula assumes that the entire amount is taxable and that the GST rate is 18%.

6. Integrated Worked Application

Illustrative facts: Alpha Machinery, registered in Maharashtra, sells equipment to Beta Industries, registered in Karnataka. Alpha dispatches the equipment from Maharashtra to Beta’s Karnataka plant. The invoice value before GST is ₹500,000. Packing charged separately is ₹10,000. A price-linked discount of ₹20,000 is shown on the invoice. GST rate is 18%.

Analysis:

  • Movement terminates in Karnataka; the place of supply is Karnataka.
  • Supplier location and place of supply are in different States; the supply is inter-State.
  • Taxable value is:
₹500,000 + ₹10,000 − ₹20,000 = ₹490,000
  • IGST is:
₹490,000 × 18% = ₹88,200
  • Invoice total is ₹578,200.

The discount is deductible because it is shown at or before supply and linked to the transaction. If the discount had been offered later, the section 15(3) conditions would need to be examined.

7. Illustrative Case Study: Digital Group Services

Background: Orion India Pvt. Ltd. receives automated cloud-hosting access from Orion Singapore. It also receives strategic advice through monthly video conferences from an independent consultant in the United Kingdom. The Singapore entity and Indian entity are under common control.

Problem: Determine whether GST arises, identify the place of supply and decide how valuation should be approached.

Analysis: The Singapore cloud service is an imported service if the statutory conditions are satisfied. Since the parties are related establishments or persons, the ordinary third-party price may not be available; the valuation rules for related or distinct persons must be considered. Reverse charge may apply to the Indian recipient.

The UK consultancy is not automatically an OIDAR service merely because meetings occur online. Its classification is based on the substantive service. If the consultant is outside India and the Indian company receives the service in India, import-of-service and reverse-charge consequences must be examined. The contract, invoice, payment evidence, place-of-supply analysis and related-party relationship should be retained.

Approach: Orion should create a transaction file containing the agreement, supplier status, GSTIN or foreign registration details, service description, user location, invoice date, payment date, valuation basis and reverse-charge computation. It should separately test whether input tax credit is available.

Outcome: The correct result depends on classification and statutory conditions, not merely on the location of the server or the use of video conferencing.

Learning points: Technology changes the delivery mechanism, but it does not replace the statutory tests for supply, time, place, value and recipient status.

8. Professional Controls and Common Errors

Common errors include treating every advance as taxable for goods, ignoring reverse charge, using the billing address without applying the place-of-supply rule, reducing GST for unsupported post-supply discounts, and excluding all reimbursements as pure-agent payments.

Best practice includes:

  • maintaining a time-of-supply matrix for invoice, completion, payment and advance dates;
  • classifying customers as registered, unregistered, related or distinct persons;
  • mapping each service category to its specific place-of-supply rule;
  • documenting discounts and recipient input-tax-credit reversals;
  • separating principal consideration from pure-agent recoveries;
  • reconciling invoices, e-invoices, ledgers, returns and payment records; and
  • reviewing amendments, circulars, notifications and court decisions before filing.

AI tools can assist with invoice classification, anomaly detection and contract extraction, but professional responsibility remains with the tax adviser. Sensitive invoices and contracts should be processed under approved data-governance controls, with human review of exceptions and legal interpretation.

Challenges and Limitations

GST outcomes can be difficult where contracts contain several supplies, delivery is split across locations, services are continuously performed, parties are related, or digital consumption is difficult to locate. Place-of-supply rules may produce results different from commercial intuition. Valuation disputes often concern whether an amount is consideration, a subsidy, a reimbursement or a genuine discount. These issues require evidence, not only accounting entries.

Chapter Summary

Time of supply identifies the tax period in which liability arises. Goods and services have different rules, with special provisions for advances, vouchers, continuous supplies, reverse charge and rate changes. Place of supply determines whether a transaction is intra-State or inter-State and provides the jurisdictional link for goods, services, imports, exports and digital supplies. Value of supply normally begins with transaction value but requires adjustments for incidental expenses, subsidies, discounts, taxes, interest, related-party dealings and pure-agent reimbursements. Accurate GST advice therefore depends on coordinated legal classification, contractual analysis, invoice control, valuation evidence and awareness of current amendments.
