## The 'Business' Test
For most supplies, GST kicks in only when the transaction is in the course or furtherance of business — a private/personal sale by an individual is NOT a supply.
### Definition of Business – Section 2(17)
'Business' includes:
(a) Any trade, commerce, manufacture, profession, vocation, adventure, wager or any similar activity, whether or not for pecuniary benefit.
(b) Any activity or transaction incidental or ancillary to (a).
(c) Any activity or transaction in (a) — whether or not there is volume, frequency, continuity or regularity.
(d) Supply or acquisition of goods including capital goods in connection with commencement or closure of business.
(e) Provision by a club, association, society of facilities or benefits to its members.
(f) Admission, for a consideration, of persons to any premises (zoo, cinema, exhibition).
(g) Services as the holder of an office accepted in the course of trade/profession.
(h) Activities of a race club (including book-maker, totalisator).
(i) Any activity or transaction by Central Government, State Government, or local authority in which they are engaged as public authorities.
### Key Insights
1. No profit motive needed: Even charitable, not-for-profit activities can be 'business' (relevant for NGOs, religious trusts running commercial canteens).
2. One-off transactions count: Volume / frequency / regularity not required.
3. Ancillary activities count: Sale of fixed assets (e.g. old company car) is incidental to business → covered.
4. Setup & closure activities count: Purchase of machinery before commencing business; sale of stock on closure — both are 'business'.
5. Government public functions are business for GST purposes — but most are then exempted by notification.
### Critical Exception – Import of Service
For import of services for consideration, the 'business' condition is NOT required (Section 7(1)(b)). Even a private individual importing a service must pay GST.
### Why This Matters
If the seller is a private individual not engaged in business, their sale is outside GST. But the moment they sell repeatedly, or as an extension of business, GST may attract.
