Hobby or Business? How to Tell When Selling Online in Australia Counts as a Business

You are running a business, not a hobby, if you sell with an intention to make a profit, in a businesslike way, repeatedly, and at a scale like others in your field; no single factor decides it. It matters because hobby amounts need not be declared to the ATO, while business income must be declared in your annual return. If you are buying stock to resell on Amazon.com.au month after month, you are very likely in business territory. This is general information, not tax or legal advice; confirm with the ATO or a registered tax agent.

What is a hobby, and what is a business?

Business.gov.au describes a hobby as "a pastime or leisure activity conducted in your spare time for recreation or pleasure". A business is an activity carried on to make a profit, with the other features below. The ATO publishes its own list of indicators that courts have looked at, and its rulings on hobbies say money from a hobby is generally not assessable income and its costs are not deductible. Use the business.gov.au summary as a starting point, and ask the ATO or a registered tax agent about a close case. Write down why you think your activity is a business, for example your plan, your stock purchases and how often you list, so the reasoning is on file if the ATO ever asks.

Selling your own unwanted things is a classic hobby-type activity. Buying products to resell, listing them on a marketplace, advertising them and reinvesting the proceeds is a different pattern.

What factors tell them apart?

Business.gov.au lists the following. None is conclusive alone:

For Amazon sellers the signals stack up quickly: a Professional plan subscription, repeated stock purchases, advertising spend, a brand registered with a trade mark, and a growth plan. A seller who clears out a wardrobe once is on the other side.

Does making a loss mean it is a hobby?

Not by itself. The ATO's rulings say that the presence of losses alone cannot support the conclusion that someone does not genuinely believe they will eventually make a profit. That is the ATO's approach to a start-up phase. But even for a genuine business, losses can be restricted. The ATO's "non-commercial losses" rules generally stop a loss from being used against other income, such as salary, in the year unless a test is met, and a deferred loss can usually be carried forward. Confirm the tests with a tax agent. The ATO can also issue a private ruling in uncertain cases.

What changes for tax if it is a business?

• Income. You declare your income to the ATO in your annual return and generally claim business expenses as deductions.
• ABN. Hobbyists are not eligible for an ABN, while a business can apply, and it is free.
• GST. You must register once GST turnover is A$75,000 or more, and you may register earlier. See GST for Amazon sellers in Australia.
• Records. Most business records must be kept for 5 years.
• Tax return. Every business must hold a TFN and lodge an annual tax return, and late lodgement or payment can attract penalties.

Income tax detail, sole trader versus company and deductions are in income tax for Amazon sellers in Australia.

What does this mean for opening an Amazon account?

Amazon's registration guide lets individuals choose "None, I am an individual" where it asks for a company registration number, so Amazon does not require an ABN for an individual account. That is Amazon's rule for the account. It does not decide your tax status. The ATO looks at what you are actually doing, not which Amazon plan you picked.

Without an ABN, businesses paying you must withhold 47% of payments, which is a reason hobbyists sometimes use a Statement by a supplier form. That rule is for payments from businesses to you, not for marketplace payouts, so ask your agent how it applies. Plan choice is covered in Amazon Australia Individual vs Professional, and the ABN question in do you need an ABN to sell on Amazon Australia.

What stays the same either way?

The Australian Consumer Law applies if you sell goods, whether the activity is a hobby or a business. Faulty goods, misleading descriptions and product safety rules do not wait for you to be a business. See Australian Consumer Law and Amazon returns and Product Safety for Amazon sellers in Australia.

Worked example: two sellers on Amazon

Sam clears out a cupboard and lists a dozen second-hand items over a few weeks, then stops. There is no plan to profit, no repeat buying, and no records beyond the sale confirmations. That looks like a private clear-out rather than a business, though a tax agent should confirm.

Priya orders 300 units of a kitchen product from a supplier, lists it on Amazon.com.au under a Professional plan, runs ads, reorders every two months and tracks her costs in a spreadsheet. Every factor on the table above points to a business. She should hold an ABN, declare her income, keep her invoices and watch her GST turnover against A$75,000.

Most real sellers sit between the two. Where you are unsure, treat the stronger signals as the guide and write down why you think the activity is, or is not, a business on the day you decide.

A short self-check

1. Is a profit the aim, even if it takes a year or two?
2. Do you buy stock to resell, repeatedly?
3. Do you track income and costs, and keep invoices?
4. Is your activity similar in scale to other sellers in your category?
5. Have you spent on a plan, ads, labels or a brand?

Mostly yes means treat it as a business. If you are still unsure, a registered tax agent can give you a view, and the ATO can give a private ruling for a formal answer.

FAQ

Is selling on Amazon a hobby or a business? It depends on what you do. Intention to profit, repeated activity, a businesslike set-up and scale are weighed together. Regular stock buying, listings and ads usually mean a business.

Do I have to declare hobby income to the ATO? Business.gov.au says amounts from a hobby need not be declared, and hobby losses cannot be claimed. If you are unsure which you are, get advice before deciding not to declare.

Can I get an ABN for a hobby? No. Business.gov.au says hobbyists are not eligible for an ABN, while a business can apply and registration is free. If you are unsure which side you are on, that is a sign to ask a registered tax agent before applying.

Is there a dollar amount where a hobby becomes a business? There is no single dollar figure in the test. The A$75,000 figure is the GST registration threshold, not a hobby cut-off.

What if I started as a hobby and it grew? The activity can change character as it grows. Keep records from the start, and talk to a tax agent about when you began carrying on a business.

Does the Australian Consumer Law apply to a hobby seller? Yes. If you sell goods, the law applies whether the activity is a hobby or a business, so faulty goods and misleading descriptions are your responsibility either way.
