Section 2 at a Glance
Section 2 begins with an important interpretive rule: the definitions apply throughout the Act unless the context otherwise requires. Therefore, when another provision uses a defined expression, the statutory definition should normally be checked before relying on its ordinary commercial meaning.
1. How Section 2 Should Be Read
Section 2 is not one single definition. It is a collection of statutory definitions covering people, transactions, tax concepts, records, authorities, supplies, goods, services, turnover, registration-related concepts and several specialised GST expressions.
The words used in Section 2 frequently connect with provisions elsewhere in the Act. For example, “aggregate turnover” affects registration and composition questions; “goods” and “services” affect the classification of a supply; “recipient” and “supplier” can affect liability; and “input tax” and “input tax credit” are central to credit eligibility.
The phrase “unless the context otherwise requires” is also important. It prevents the definitions from being applied mechanically where the surrounding statutory provision clearly requires a different contextual interpretation.
2. Important Definitions Every GST Professional Should Know
2.1 Aggregate Turnover — Section 2(6)
Aggregate turnover broadly brings together the taxable supplies, exempt supplies, exports and inter-State supplies of persons having the same PAN, computed on an all-India basis. Central tax, State tax, Union territory tax, integrated tax and cess are excluded. Inward supplies on which tax is payable by the recipient under reverse charge are also excluded from the supplier's aggregate turnover.
Why it matters: The concept is used in several GST provisions, particularly registration thresholds, composition eligibility and other compliance tests.
2.2 Goods — Section 2(52)
“Goods” covers movable property, subject to the exclusions and inclusions specified by the definition. The definition specifically includes actionable claims and certain items connected with land where the statutory conditions are satisfied, while excluding money and securities.
2.3 Services — Section 2(102)
Services are defined broadly as anything other than goods, money and securities, with the specific inclusion concerning activities relating to the use of money or its conversion where separate consideration is charged.
The definition is deliberately broad. Therefore, a transaction does not become a non-service merely because it is not described as a traditional professional or commercial service.
2.4 Person — Section 2(84)
The term “person” is wider than an individual. It includes entities such as companies, firms, LLPs, associations or bodies of individuals, HUFs and certain other legal or juridical persons.
2.5 Recipient — Section 2(93)
The definition identifies the recipient differently depending on whether consideration is payable. Where consideration is payable, the person liable to pay it is relevant. Where there is no consideration for goods, the definition uses the person to whom the goods are delivered, made available, or whose possession or use is involved as specified.
2.6 Supplier — Section 2(105)
The supplier is the person supplying the relevant goods or services or both. The definition works together with the charging, registration, invoice and place-of-supply provisions.
2.7 Input Tax — Section 2(62) and Input Tax Credit — Section 2(63)
Input tax is the tax covered by the statutory definition in relation to a registered person. Input tax credit is the credit of input tax. These definitions form the starting point for the detailed eligibility and restriction provisions under Chapter V.
2.8 Exempt Supply — Section 2(47)
The definition covers supplies attracting nil rate or supplies that are wholly exempt under the relevant GST provisions and also includes non-taxable supply. This definition becomes important when applying provisions dealing with common input tax credit and exempt turnover.
2.9 Electronic Commerce and Electronic Commerce Operator — Sections 2(44) and 2(45)
GST law separately defines electronic commerce and the electronic commerce operator. These definitions support the special compliance framework applicable to specified supplies made through electronic platforms.
2.10 Input Service Distributor — Section 2(61)
The definition of Input Service Distributor has undergone an important change. From 1 April 2025, the definition expressly covers input-service invoices, including invoices for services liable to tax under specified reverse-charge provisions, received for distinct persons and requiring distribution of the eligible input tax credit in the manner provided in Section 20.
2.11 Online Gaming, Online Money Gaming and Specified Actionable Claim
The law introduced specific definitions for online gaming, online money gaming and specified actionable claims in the 2023 legislative changes. These definitions were part of the statutory framework introduced to address betting, gambling, casinos, horse racing, lottery and online money gaming.
2.12 Local Authority — Section 2(69)
The definition identifies specified constitutional and statutory bodies that qualify as local authorities. It is not enough for an organisation to be casually described as a “local body”; the statutory definition has to be examined.
3. Major Amendments to Section 2 — Legislative Timeline
Section 2 has not remained unchanged since 1 July 2017. Several amendments have modified, omitted or inserted definitions. For professional work, it is therefore important to identify the version of the definition applicable to the relevant tax period.
Effective 1 Feb 2019
Effective 29 Mar 2018
Effective 1 Jan 2020
Effective 1 Oct 2023
Effective 1 Apr 2025
1 Apr & 1 Oct 2025
4. GST Council Recommendations Behind Important Changes
4.1 Input Service Distributor — GST Council Meetings
The change to the ISD definition was preceded by detailed consideration in the GST Council. The 50th GST Council Meeting considered whether the ISD route should become mandatory for distribution of common input-service credit and specifically considered common services subject to reverse charge. The Council authorised the Law Committee to formulate the required law amendments.
The 52nd and 53rd Council records subsequently contain the proposed revised wording for Section 2(61) and related amendments to Section 20 and Rule 39. This is a useful example of how a GST Council recommendation moves through legal drafting and ultimately becomes an effective statutory amendment through the Finance Act and commencement notification.
4.2 Online Gaming — 51st GST Council Meeting
The 51st GST Council considered amendments concerning online gaming, online money gaming and specified actionable claims. The proposal included insertion of definitions in Section 2 and corresponding changes to the CGST Act framework. These changes were subsequently enacted and made effective from 1 October 2023.
5. Important Notifications and Official Gazette Trail
For Section 2, the amendment trail should be read as a chain rather than as a single document. A professional historical review should normally identify the following:
| Change | Legislative instrument | Commencement | Practical significance |
|---|---|---|---|
| 2018 amendments to Section 2 | CGST (Amendment) Act, 2018, Section 2 | 1 Feb 2019 through Notification No. 02/2019-Central Tax | Several definitions changed or were omitted. |
| Online gaming definitions | CGST (Amendment) Act, 2023 | 1 Oct 2023 through Notification No. 48/2023-Central Tax | Inserted online gaming, online money gaming and specified actionable claim definitions. |
| ISD definition | Finance Act, 2024, Section 11 | 1 Apr 2025 through Notification No. 16/2024-Central Tax | Expanded the statutory definition of ISD. |
| Additional Section 2 changes | Finance Act, 2025, Section 121 | Parts effective 1 Apr 2025 and 1 Oct 2025 | Further modified ISD wording and introduced local-fund/municipal-fund explanations and unique identification marking. |
Official Gazette publication is important because it provides the formal legislative or notification trail. For a legal opinion, audit defence or departmental proceeding, the applicable Act, amendment provision and commencement notification should be retained together.
6. Circulars and Administrative Clarifications Relevant to Section 2
Circulars do not rewrite Section 2. They provide administrative clarification on how particular definitions and related provisions are to be understood or applied in specified situations.
Circular No. 159/15/2021-GST — Intermediary
This circular is relevant when analysing the concept of “intermediary” under the GST framework. The clarification emphasises the distinction between a person who arranges or facilitates the main supply and a person who supplies goods or services on his own account.
Circular No. 230/24/2024-GST — Advertising services
The circular discusses situations where an advertising company facilitates the provision of media space and explains the intermediary analysis by reference to the statutory definition. This demonstrates why the precise wording of a definition can materially affect the GST treatment of a cross-border service.
CBIC FAQs — Aggregate Turnover and Other Definitions
CBIC FAQs have also addressed practical application of definitions such as aggregate turnover, government, local authority, goods and services. These FAQs are useful for understanding administrative explanations, but for a formal legal position the Act, Rules, notifications, circulars and applicable judicial decisions should be examined together.
7. Practical Examples — How Section 2 Changes the GST Answer
A company has ₹18 crore turnover in Telangana and ₹5 crore in Karnataka under the same PAN. For a provision that uses “aggregate turnover”, looking only at the Telangana GSTIN can produce the wrong result. The definition operates on the statutory PAN-level, all-India basis.
A supplier has ₹19 lakh of outward supplies and receives ₹4 lakh of inward legal services on which the recipient is liable to pay GST under reverse charge. The ₹4 lakh inward supply is not simply added to the supplier's aggregate turnover merely because GST is payable on it. The definition specifically excludes inward supplies on which tax is payable under reverse charge.
A contractor supplies machinery and separately provides installation and maintenance. The classification of the components requires the statutory definitions of goods and services, followed by the provisions governing composite or mixed supplies where applicable. Calling the entire arrangement “service” merely because it is under one contract may be insufficient.
A company has a head office and branches in several States. The head office receives common input services such as audit, software or professional services. From 1 April 2025, the revised ISD definition specifically addresses relevant input-service invoices, including specified reverse-charge services. The company therefore needs to examine the ISD registration and distribution provisions rather than treating the old mechanism as unchanged.
An online platform receives money or money's worth from players in expectation of winning money or money's worth. The statutory definitions introduced in 2023 become directly relevant to determine whether the activity falls within the specialised GST framework for online money gaming and specified actionable claims.
An organisation may describe itself as a local body in its internal documents. That description alone does not decide whether it is a “local authority” for GST. Section 2(69) contains the statutory test, and the 2025 amendments added explanations concerning local fund and municipal fund. The legal status must therefore be tested against the definition.
Suppose a GST audit examines FY 2018-19. The officer and taxpayer should not automatically use the present wording of every definition. If the issue concerns a definition amended from 1 February 2019, the exact transaction date and the effective date of the amendment become important.
8. Professional Method for Using Section 2 in Audit and Compliance
- Identify the exact defined expression. Do not rely on a general dictionary meaning.
- Check the clause number. Similar terms can have separate statutory meanings.
- Check the relevant date. Historical amendments can change the applicable definition.
- Read the linked provision. A definition normally operates with the section that uses it.
- Check Rules and notifications. Definitions often connect to prescribed procedures or thresholds.
- Check circulars where available. Administrative clarification may explain application in a particular fact pattern.
- Check judicial interpretation for disputed issues. A statutory definition and its judicial interpretation should be considered together where litigation is involved.
- Document the amendment trail. For an audit file, keep the relevant Act, Gazette/notification and supporting circular or clarification.
