Understanding 'Supply' and 'Goods'
From the TAXATION 1 curriculum
TL;DR
In taxation, 'supply' refers to any transfer of ownership or right, often for consideration, while 'goods' are generally tangible personal property. Understanding these definitions is crucial as they determine when and what transactions are subject to Goods and Services Tax (GST). Incorrectly identifying a supply or classifying an item can lead to significant tax compliance issues.
1. The Mental Model
Think of 'supply' as any economic activity where something valuable changes hands, and 'goods' as the physical items that often change hands. If it's not a service, it's probably goods.
2. The Core Material
In GST legislation, the terms 'supply' and 'goods' have specific, broad definitions that often go beyond their everyday meanings. Getting these right is fundamental to determining tax obligations.
What is a 'Supply'?

A supply is the central concept for GST. If there's no supply, there's no GST. It's broadly defined to include almost any form of economic activity, not just sales.
Here's what generally constitutes a supply:
- Provision of goods: Selling a car, giving away merchandise.
- Provision of services: Haircutting, consulting, legal advice.
- Any other thing done: Granting a right, leasing property, allowing use of intellectual property.
Key characteristics of a supply:
- For consideration: This means something is given in return (money, another good/service, etc.). Most commercial supplies are for consideration.
- In the course or furtherance of an enterprise: The activity must be part of a business or economic activity.
- Even without consideration: Some specific types of supplies, like certain fringe benefits, can be supplies even if nothing is given in return.
The definition is incredibly wide to capture almost all commercial transactions.
What are 'Goods'?

Goods are generally tangible personal property. This means physical items you can touch and move.
Here's what typically falls under 'goods':
- Personal property: Cars, computers, clothing, furniture.
- Animals: Livestock.
- Fixtures: Items attached to land, like machinery bolted down, but only if they are to be severed from the land.
- Gas and electricity: Although not traditionally "tangible" in the same way as a car, legislation often specifically includes them.
What are NOT goods?
- Real property (land and buildings): These are treated separately under GST law, even though they are tangible.
- Services: Actions performed for others.
- Money: Currency itself isn't a good when used as a medium of exchange.
- Intellectual property rights: Patents, copyrights, trademarks are usually considered services or "other things done."
Here's a simple decision flow to help you classify:

A["Is it a physical item?"] -->|Yes| B["Can it be moved?"]
B -->|Yes| C["Is it land or an attached building?"]
C -->|No| D["It's likely Goods"]
B -->|No| E["Is it to be severed (e.g., fixture sold separately)?"]
E -->|Yes| D
E -->|No| F["It's likely Real Property"]
A -->|No| G["Is it an action or right?"]
G -->|Yes| H["It's likely a Service or Other Supply"]
G -->|No| I["Review specific legislation for exceptions (e.g., gas/electricity)"]
3. Worked Example
Imagine you own "TechRecycle Ltd," a business that refurbishes and resells used electronics.
Scenario: You purchase a batch of old laptops from "OfficeClearance Co." for \$5,000. You then spend \$1,000 on parts and labor to fix them up. Finally, you sell the refurbished laptops to "Student Bargains Inc." for \$8,000.
Let's break down the 'supply' and 'goods' aspects:
-
Your purchase from OfficeClearance Co.:
- Supply: OfficeClearance Co. making a supply to you.
- Goods: The old laptops are clearly tangible personal property, so they are goods.
- Consideration: \$5,000.
-
Your refurbishment efforts (parts and labor):
- Parts: If you buy new screens or RAM, these are goods supplied to you by your supplier.
- Labor: If you hire a technician, their work is a service supplied to you. If your employees do the work, their wages aren't a supply for GST purposes (but the finished refurbished laptop will be).
-
Your sale to Student Bargains Inc.:
- Supply: You are making a supply to Student Bargains Inc.
- Goods: The refurbished laptops are still tangible personal property, so they are goods.
- Consideration: \
