Goods and Services Tax (GST) is fundamentally a tax on supply. Unlike a traditional sales tax, which generally focused on the sale of goods, GST adopts a wider taxable-event concept covering supplies of goods, services and, in appropriate cases, both together. The legal question is therefore not merely whether a sale has occurred, but whether the transaction satisfies the statutory conditions of supply under the Central Goods and Services Tax Act, 2017 (CGST Act), the Integrated Goods and Services Tax Act, 2017 (IGST Act), and related rules and notifications.
For a tax professional, classification of a transaction as supply is the first stage of analysis. If there is no supply, GST ordinarily does not arise. If there is a supply, the professional must then determine the nature of the supply, the time and value of supply, the applicable rate, the place of supply, and the documentation and compliance consequences.
This chapter explains the statutory meaning and scope of supply, consideration, business purpose, transactions without consideration, composite and mixed supplies, principal–agent dealings, related-party transactions, imports, exports and the activities covered by the statutory Schedules.

Apply a systematic professional framework to transaction analysis.
1. The Taxable Event under GST
The taxable event is the event that gives rise to a tax liability. Under the GST framework, the principal taxable event is supply. Section 7 of the CGST Act provides the core statutory definition, while section 9 imposes central GST on intra-State supplies and the IGST Act governs inter-State supplies, imports and exports.
The concept is deliberately broad. It includes conventional transactions such as sale and purchase, but also covers transfer, barter, exchange, licence, rental, lease and disposal when the statutory conditions are met. This design prevents tax avoidance through contractual forms that do not use the word “sale”.
A transaction should therefore be examined by substance and statutory character rather than by its commercial label. Calling a transaction a “reimbursement”, “support arrangement”, “licence fee” or “deposit” does not by itself determine its GST treatment.
2. Statutory Meaning of Supply
In broad terms, supply includes:
sale;
transfer;
barter;
exchange;
licence;
rental;
lease; and
disposal.
These activities are generally supplies when made or agreed to be made for a consideration by a person in the course or furtherance of business. The statutory framework also includes certain transactions without consideration under Schedule I and specifically includes importation of services for consideration, whether or not connected with business.
The major elements may be represented as follows:

2.1 Supply for consideration
Consideration is an important element of the general rule. It may be monetary or non-monetary and may be provided by the recipient or by another person. A payment need not always be made directly to the supplier. For example, a third party may discharge an obligation on behalf of the recipient.
Consideration includes:
payment in money;
payment in kind;
set-off or adjustment;
exchange of goods or services; and
an act or forbearance undertaken in response to the supply.
A refundable deposit is generally not consideration merely because it is paid. It may become consideration if the supplier applies or appropriates it towards the supply. A security deposit that is retained because of breach or adjusted against dues requires examination of the contract and the actual conduct of the parties.
A grant or subsidy is not automatically consideration. Subsidies directly linked to the price may be included in value under section 15, subject to the statutory treatment of subsidies provided by governments. The legal nature and linkage of the payment must be examined carefully.
2.2 Supply in the course or furtherance of business
The general rule requires the activity to be in the course or furtherance of business. “Business” is defined widely and includes trade, commerce, manufacture, profession, vocation, adventure, wager and similar activities, whether or not undertaken for profit. It also includes activities connected with or incidental to the main activity and certain activities of public authorities and clubs or associations.
Profit motive is not essential. A non-profit organisation may make taxable supplies. Similarly, a single commercial adventure may qualify even if it is not part of a continuing enterprise.
The following factors help determine business connection:
regularity or organised nature of the activity;
commercial scale;
connection with the entity’s objects or operations;
use of business assets or resources;
intention and contractual structure; and
whether the activity produces or is intended to produce economic value.
A purely personal gift is ordinarily outside the general rule, unless a specific provision such as Schedule I applies. A transfer of business assets, however, may be taxable even without consideration when input tax credit has been availed.
2.3 Supply without consideration
Schedule I identifies specified activities that are treated as supplies even when no consideration is present. The principal categories are:
Permanent transfer or disposal of business assets where input tax credit has been availed.
Supply between related persons or between distinct persons in the course or furtherance of business, even without consideration.
Supply of goods by a principal to an agent, or by an agent to a principal, where the agent undertakes to supply or receive goods on behalf of the principal.
Importation of services by a person from a related person or from another establishment outside India, in the course or furtherance of business, even without consideration.
These rules prevent artificial avoidance by shifting value without issuing an ordinary invoice or by describing a transfer as internal.
3. Activities That Are Not Supply: Schedule III
Schedule III lists activities treated neither as a supply of goods nor as a supply of services. Important examples include:
services by an employee to the employer in the course of employment;
services by courts or tribunals;
functions performed by Members of Parliament, State Legislatures, constitutional office-holders and certain local authority functions;
funeral, burial, crematorium or mortuary services, including transportation of the deceased;
sale of land; and
sale of completed buildings, subject to the statutory exception concerning construction intended for sale before completion certificate or first occupation.
Actionable claims, other than specified taxable categories such as betting, gambling and lotteries, are also treated according to the statutory framework and should not be assumed to be taxable merely because value is transferred.
Schedule III is not an exemption schedule. An exempt supply is still a supply but is relieved from tax. An activity outside Schedule III is not a supply at all. This distinction affects registration, input tax credit, invoicing and reporting.
4. Schedule II: Classification as Goods or Services
Schedule II does not independently create a supply. Instead, where an activity is already a supply under section 7, it helps determine whether the supply is treated as goods or services.
Examples include:
transfer of title in goods: supply of goods;
transfer of the right in goods without transfer of title: supply of services;
lease, tenancy, easement or licence to occupy land: supply of services;
lease or letting of a building for business or commerce: supply of services;
treatment or process applied to another person’s goods: supply of services;
renting of immovable property: supply of services;
construction of a complex, building or civil structure intended for sale before completion or first occupation: supply of services, subject to statutory conditions;
development, design or software-related activities: generally analysed according to the facts and applicable classification rules.
The classification question is important because it affects place of supply, rate, time of supply and documentation.
5. Composite and Mixed Supplies
Commercial transactions often contain several elements. GST therefore distinguishes between composite and mixed supplies.
5.1 Composite supply
A composite supply consists of two or more taxable supplies of goods or services, or both, which are naturally bundled and supplied together in the ordinary course of business. One component is the principal supply. The entire composite supply is treated as a supply of the principal supply.
Illustration: transportation of goods, packing, loading, transit insurance and related handling supplied as one integrated service may constitute a composite supply where transportation is the principal supply.
Natural bundling is assessed objectively. Relevant indicators include:
ordinary business practice;
consumer expectation;
whether the elements are normally supplied together;
whether one element is ancillary to another;
the pricing and contractual structure; and
whether separate purchase is commercially realistic.
The principal supply is not necessarily the most expensive element. It is the predominant element that gives the bundle its essential character.
5.2 Mixed supply
A mixed supply consists of two or more individual supplies made together for a single price, where the combination does not constitute a composite supply. The entire bundle is treated as the supply attracting the highest rate of tax among its components.
Illustration: a festival hamper containing chocolates, cosmetics, juices and other independently marketable products sold for one consolidated price may be a mixed supply if the items are not naturally bundled.
The single-price requirement is significant. If items are separately priced and supplied independently, each supply may be taxed according to its own classification, subject to the contract and applicable provisions.

6. Principal–Agent Transactions
Principal–agent arrangements create difficult supply questions because the agent may act merely as an intermediary or may undertake a supply on behalf of the principal. Schedule I specifically covers supplies of goods between a principal and an agent in specified circumstances, even without consideration.
The focus is not solely on the title of the agreement. The professional should examine:
whether the agent has authority to receive or supply goods on behalf of the principal;
whether the agent issues invoices in its own name or the principal’s name;
whether the agent controls possession, title or risks;
whether the agent is merely arranging a supply or actually undertaking the supply;
whether goods are supplied by the principal to the agent for onward supply; and
whether the statutory principal–agent conditions are satisfied.
A commission agent who only arranges a sale may make a supply of agency service to the principal. Separately, movement of goods between principal and agent may be a deemed supply under Schedule I if the statutory test is satisfied. Each legal relationship must therefore be analysed separately.
7. Related Persons and Distinct Persons
GST contains special rules for transactions between related persons and distinct persons. Persons may be related where, for example, they are officers or directors of one another’s businesses, legally recognised partners, employer and employee, or entities under common control. The detailed statutory explanation must be applied to the facts.
Branches, establishments or registrations of the same legal entity in different States are treated as distinct persons. A supply between them can therefore be taxable even though there is no separate legal personality and even if no consideration is charged.
Examples include:
transfer of goods from a Maharashtra registration to a Karnataka registration;
provision of centralised accounting or information technology support by one registration to another;
allocation of common services by a head office to branch registrations; and
transfer of business assets between distinct registrations.
Valuation must then be determined under section 15 and the valuation rules. Input tax credit availability may influence the applicable valuation method in specified circumstances, but it does not eliminate the need to identify the supply and issue appropriate documentation.
8. Imports and Exports
8.1 Import of goods
Import of goods into India is treated as an inter-State supply under the IGST Act. IGST is generally collected at the customs stage, along with applicable customs duties. The importer must examine classification, customs valuation, place of importation and eligibility for input tax credit.
8.2 Import of services
Import of services generally requires three elements:
the supplier is located outside India;
the recipient is located in India; and
the place of supply is in India.
Importation of services for consideration is included even if it is not in the course or furtherance of business. Further, importation of services from a related person or from another establishment outside India, in the course or furtherance of business, may be treated as supply even without consideration under Schedule I.
The reverse charge mechanism may apply to specified imports of services. The recipient must verify the applicable notification, determine the taxable value and discharge tax correctly.
8.3 Export of goods and services
Exports are zero-rated supplies under the IGST framework, subject to statutory conditions. Export of goods generally requires the goods to be taken out of India. Export of services requires, among other conditions, that:
the supplier is located in India;
the recipient is located outside India;
the place of supply is outside India;
payment is received in convertible foreign exchange or in permitted Indian rupees; and
the supplier and recipient are not merely establishments of the same person, subject to statutory wording and exceptions.
Zero rating is different from exemption. A zero-rated supplier may generally claim input tax credit and seek refund in the prescribed manner, subject to compliance. The place-of-supply rules must be applied carefully because an apparently international transaction may fail the export conditions if the place of supply is in India or the parties are merely establishments of the same person.
9. Consideration in Difficult Transactions
9.1 Barter and exchange
Barter and exchange are expressly included in the scope of supply. If a consultant provides services in return for equipment, both legs may constitute supplies. The value must be determined under the valuation provisions rather than assuming that no GST applies because no cash changed hands.
9.2 Free samples and gifts
Free samples and gifts may have different treatments depending on whether they fall under Schedule I, whether input tax credit was availed, and whether they are supplied in the course of business. Section 17(5)(h) also restricts input tax credit for goods disposed of by way of gift or free samples, subject to statutory exceptions. The supply analysis and the input tax credit analysis must not be confused.
9.3 Employee-related transactions
Services by an employee to the employer in the course of employment are covered by Schedule III and are not supplies. Employer-provided benefits outside the employment relationship require separate analysis. The existence of a payroll deduction does not automatically establish a taxable supply; the contractual and statutory context matters.
9.4 Reimbursements and pass-through amounts
A reimbursement may be part of the value of the supplier’s own service, or it may qualify for treatment as a pure-agent expense under the valuation rules if all prescribed conditions are satisfied. Merely describing an amount as a reimbursement does not remove it from taxable value.
10. Professional Decision Framework
A tax consultant can apply the following sequence:
Identify the parties and their GST registrations.
Describe the transaction in commercial and legal terms.
Determine whether goods, services, money, actionable claims or immovable property are involved.
Test section 7 and the presence of consideration.
Test the business connection requirement.
Examine Schedule I for supplies without consideration.
Examine Schedule III for activities outside supply.
Use Schedule II to classify goods or services where relevant.
Determine whether the arrangement is composite or mixed.
Apply related-person, distinct-person, principal–agent and import/export rules.
Determine place of supply, time of supply, value, rate, exemption and reverse charge.
Preserve contracts, invoices, correspondence, valuation records and evidence of movement or payment.
This sequence separates the existence of supply from later questions. A common professional error is to begin with the tax rate before establishing whether a taxable supply exists.
Applied Case: Inter-State Head Office Support
Illustrative case.
Background
A company has GST registrations in Delhi and Tamil Nadu. The Delhi registration employs an information technology team that provides software maintenance, cybersecurity and help-desk support to the Tamil Nadu registration. The Delhi office allocates costs monthly, but the Tamil Nadu office makes no direct payment.
Problem
Is there a supply even though both registrations belong to the same company and no separate consideration is charged?
Analysis
The two registrations are distinct persons under GST. The support activities are services provided in the course or furtherance of business. Schedule I covers supplies between distinct persons in the course or furtherance of business even without consideration. The absence of a cash payment therefore does not prevent the existence of supply.
The company must determine the appropriate value under the valuation provisions, identify the place of supply and issue the required tax invoice. If the recipient is eligible for input tax credit and the statutory conditions are met, the economic tax cost may be neutral, but compliance obligations remain.
Outcome
The Delhi registration should treat the support as a taxable supply to the Tamil Nadu registration, subject to the applicable inter-State provisions. The transaction should be supported by service descriptions, allocation methodology, valuation records and appropriate documentation.
Learning Points
Separate GST registrations of one legal entity are distinct persons.
Consideration is not always required under Schedule I.
Economic neutrality does not remove invoicing and reporting duties.
Valuation and input tax credit are separate stages of analysis.
11. Governance, Technology and Contemporary Practice
GST decisions should be supported by a documented tax-control process. Enterprise resource planning systems can flag transactions between GST registrations, identify unusual free-of-cost movements and compare invoices with purchase orders. Artificial intelligence may assist in contract classification, anomaly detection and extraction of clauses, but it should not replace legal review.
A responsible tax function should:
maintain a transaction-classification matrix;
map contracts to GST treatment;
review related-party and branch transactions periodically;
reconcile e-invoices, e-way bills and returns;
retain evidence for export and zero-rated supplies;
monitor amendments, circulars, notifications and judicial decisions; and
record the reasoning for uncertain classifications.
Technology produces reliable results only when master data, tax codes and business processes are correctly configured. Automated classification can reproduce an incorrect assumption at scale, making governance and human oversight essential.
12. Challenges and Limitations
The meaning of supply is broad, but its application is fact-sensitive. Difficulties commonly arise from:
distinguishing a supply from a mere transfer of money;
deciding whether a payment is consideration or a deposit;
determining whether services are naturally bundled;
separating an agency relationship from an independent resale arrangement;
valuing transactions between related or distinct persons;
identifying the place of supply in cross-border services; and
reconciling contractual wording with actual conduct.
Judicial interpretation, departmental circulars, notifications and amendments may affect the treatment of particular sectors. A professional opinion should therefore state assumptions, identify the relevant legal provisions and specify the date on which the advice is based.
Chapter Summary
GST is imposed on the taxable event of supply. The general concept covers sale, transfer, barter, exchange, licence, rental, lease and disposal made for consideration in the course or furtherance of business. Consideration may be monetary or non-monetary, and a third party may provide it. Profit motive is not essential to business.
Schedule I identifies specified supplies without consideration, including certain transfers of business assets, supplies between related or distinct persons, principal–agent goods transactions and specified importation of services. Schedule II classifies an existing supply as goods or services, while Schedule III identifies activities treated neither as goods nor services.
Composite supplies are naturally bundled and taxed according to the principal supply. Mixed supplies are not naturally bundled and are taxed at the highest applicable rate among their components. Principal–agent, related-party and distinct-person transactions require analysis of legal authority, registration status, actual conduct and valuation rules.
Imports of goods are inter-State supplies, while imports of services depend on supplier location, recipient location and place of supply, with special rules for related-party services. Exports are zero-rated when statutory conditions are satisfied. Effective GST practice requires a sequential analysis of supply, classification, valuation, place, time, rate, documentation and credit.
