An entity cannot be registered for GST unless it is carrying on an enterprise (GST Act s 23-5; 23-10). The term “carrying on an enterprise” is defined in s 9-20 as an activity, or series of activities done in the form of a business.
This is the general concept for being registered for GST. And, specifically, under the GST Act an “enterprise” does not include an activity done as a private recreational pursuit or hobby (GST Act s 9-20 (2)(b)).
The term “business” is statutorily defined in the GST Act as including any profession, trade, employment, vocation or calling, but does not include occupation as an employee.
However, the term “hobby” is not defined by the GST Act and must take its ordinary meaning.
Various ATO rulings over the years (MT 2006/1; GSTD 2006/6) have used “hobby” interchangeably with income tax laws interpreted by courts and regulators.
With this in mind, it is clear that the ATO determines that the same rules apply to hobbies from both an income tax perspective and a GST perspective. A recent media release issued by the ATO has specifically dealt with this similarity.
The ATO has warned of GST reviews in situations where an entity has irregular activities which generate little income and no profits. Clearly, their first group of taxpayers to review would be businesses who have deferred non-commercial losses by not meeting the assessable income test ($20,000).
Even though there is a GST turnover threshold of $75,000, an entity may choose to register for GST as long as they are carrying on an enterprise (or in this case, a business)
If you are currently operating at a loss but claiming GST credits, this may bring an ATO review for GST. You may need to show the ATO that you are operating a business and the following documents may be necessary to present to continue claiming GST credits:

The legislation defines “enterprise” as a business-type activity; private recreational or hobby-type activities are excluded.
Especially where income is low, activity irregular, or there are no signs of a commercial intent — the ATO may challenge GST-credit claims and demand repayment.
Regular activity, marketing, records, turnover, profit-potential — these are the sorts of indicators the ATO expects to see for a business, not a hobby.

A hobby is treated as a private recreational pursuit — not a business. As per the GST Act, only an “enterprise” qualifies for GST registration and claiming input tax credits; a hobby does not.
No — if the ATO determines the activity is a hobby rather than a genuine business enterprise, GST credits claimed on purchases may be disallowed, even if the person is registered.
They may check for business-type features: regularity and repetition of the activity, marketing or advertising efforts, a business plan, commercial scale or intent, and whether there is a realistic expectation of profit.
They may be subject to ATO review or audit, required to amend past Business Activity Statements (BAS), repay improperly claimed credits, and potentially face penalties for non-compliance.
You should take steps to document and demonstrate that the activity is a genuine enterprise: register for GST (if turnover exceeds threshold), keep a business plan, invoices, marketing materials, records of revenue and expenses, and show you are operating on a commercial, profit-oriented basis.
No. Under the GST Act, an entity cannot be registered for GST unless it is carrying on an “enterprise”. A private recreational pursuit or hobby is not considered an enterprise for GST purposes.
Changed to this company in 2019 from former accountant and love their approach of organizing everything for me face to face with Xero set up plus being able to call as much as I need for set annual fee.
