Starting your own business is exciting. But every sole trader knows that early losses are common, so you might be wondering: “I made a business loss this year – can I use it to reduce my tax on other income?” The answer is: maybe! The ATO allows some sole traders to offset business losses under the non-commercial loss rules. Let’s break it down in simple, easy-to-understand terms.

A non-commercial loss happens when your business expenses are higher than the income it earns.
Even though it’s a real business loss, the ATO calls it a “non-commercial loss” for tax purposes. This doesn’t mean your business isn’t commercial – it just means that the loss can’t automatically reduce your other income, like your salary or wages, unless your business meets certain ATO conditions. These rules help ensure that only genuine businesses, with a real intention and ability to make a profit, can use losses to reduce other taxable income.
If your business doesn’t meet these conditions, the loss isn’t gone forever. You can defer it, which means saving it to offset future profits from the same business.
So, how do you know if your loss can be claimed now or used later? Let’s walk through the key requirements set by the ATO.
The ATO wants to make sure your activity is a real business, not just a hobby. You’ll usually meet this test if:
If your activity is more of a hobby than a business, you do not need to report the income to the ATO, and any losses cannot be offset against other income.
For more information on business vs hobbies, visit the ATO website and the Australian Business website.
Before you can offset a business loss, the ATO requires your total income to be below $250,000 for the financial year.
If this combined amount is $250,000 or more, you generally won’t be able to offset the loss – even if your business passes one of the Four Tests below. Instead, the loss will usually need to be deferred.
Once you meet the income requirement, the next step is to see whether your business passes one of the Four Tests.
To use a business loss against other income, you only need to pass one of these four ATO tests:
Your business earns at least $20,000 in a year. This shows your business is more than a side hustle.
What counts as assessable income?
If you were in business for less than a year, or you stopped carrying on your business during the year, you can make a reasonable estimate of what your assessable income would have been for the full year.
Your business passes this test if it has made a taxable profit in at least 3 of the past 5 years (including the current year). A few lean years don’t automatically disqualify you – the test looks at whether your business is generally profitable over time.
Important points:
Your business passes this test if it uses real property worth $500,000 or more for business purposes on an ongoing basis. This shows your business has a significant commercial presence. Examples include farms, warehouses, or commercial premises but not your home.
To check if your real property assets reach the $500,000 threshold, you can use either:
Your business passes this test if it owns ‘other’ business assets worth $100,000 or more. This shows your business has enough investment to be considered commercially serious.

Don’t worry, your loss isn’t gone forever. You can usually defer it to offset future profits from the same business.
There’s a special exception: If your loss-making business is in primary production (such as farming) or professional arts, the ATO treats these as “excepted business activities.”
You may be able to offset your loss against other income immediately if your assessable income from other sources is less than $40,000 (excluding any net capital gain).
