# Three Foundational Definitions
Every GST problem identifies (a) who is the supplier, (b) who is the recipient, and (c) whether each is a person. These three definitions sit at the very start of Chapter 2.
## 1. Supplier — Section 2(105)
Default meaning: The person supplying the goods/services/both — and includes an agent acting on his behalf.
### Special rule for specified actionable claims
For specified actionable claims (e.g., betting, online gaming, lottery, casinos), the supplier is deemed to be:
- The person who organises or arranges (directly or indirectly) the supply, including one who owns, operates or manages a digital/electronic platform for such supply;
- Whether such actionable claims are supplied by him or through him;
- Whether consideration in money or money's worth (including virtual digital assets) is paid/conveyed to him, through him, or placed at his disposal in any manner;
- All provisions of the Act apply as if this person is the supplier liable to pay tax.
> This is the legislative basis for taxing online gaming/betting platforms (e.g., fantasy sports apps) as suppliers — even though the bettor and counterparty are private individuals.
## 2. Recipient — Section 2(93)
Three-fold definition:
| Scenario | Recipient is |
|---|---|
| (a) Consideration is payable | The person liable to pay the consideration |
| (b) No consideration + supply of goods | The person to whom the goods are delivered or made available, or to whom possession or use of the goods is given/made available |
| (c) No consideration + supply of services | The person to whom the service is rendered |
> 'Recipient' also includes a person to whom the supply is made — including an agent acting on his behalf.
### Why three limbs?
In GST, sometimes the payer and the beneficiary differ (e.g., free samples, gifts, services rendered to a third party for the contracting party). The three limbs ensure every supply has a recipient identified.
## 3. Person — Section 2(84)
'Person' includes:
a. An individual
b. A Hindu Undivided Family (HUF)
c. A company
d. A firm
e. A trust
f. A Limited Liability Partnership (LLP)
g. A local authority
h. An Association of Persons (AOP) or Body of Individuals (BOI), whether incorporated or not, in India or outside India
i. Any corporation established by/under any Central, State or Provincial Act, or a Government company as defined in Section 2(45) of the Companies Act, 2013
j. Any body corporate incorporated under the laws of a country outside India
> (The list continues in the Act with central/state government, society, etc. — examiners may quote the full list.)
## Why this definition matters
- GST registration is based on aggregate turnover per person — so what counts as a 'person' decides whether you need separate registrations.
- Related person rules (Schedule I) depend on the concept of person.
- Distinct person concept (a single PAN's GSTINs in different States) builds on this base.
