Running a business as a sole trader in Australia brings both excitement and challenges. A key hurdle that many business owners face is managing non-trading losses. These losses occur when a business activity – often not your main source of income – records a financial loss that you cannot immediately deduct from your other taxable income. The Australian Taxation Office (ATO) has strict rules on this, which is why it is important to know how you can defer such losses until your business becomes profitable.
The non-trading loss rules exist to prevent individuals from offsetting losses from activities that do not have a genuine commercial purpose against income from other ventures or sources (refer to the ATO’s detailed guidance). The positive aspect is that if you operate as a sole trader, you can defer these losses and apply them to future years when your business makes a profit.
What Are Non-Trading Losses?
Non-commercial business losses occur when you, as a sole trader or partner, suffer a financial loss from a business activity that is not related to your primary source of income. To qualify, your activity must exhibit business-like characteristics and have a commercial purpose. These losses cannot be offset against other taxable income in the same year unless certain exceptions apply or the business makes a profit.
If you cannot deduct your business losses in the current year, you can carry them forward and claim them once your business becomes profitable. This rule applies whether the losses are from an Australian or overseas source.
Understanding The Non-Commercial Loss Rules
According to the ATO, losses from activities that do not meet the requirements of a business cannot reduce your taxable income in the same year. Unless your business activity meets certain conditions, you must defer the losses and carry them forward to future years. This process is known as non-trading loss carryforward.
These rules ensure that only activities carried out with the intention of generating a profit can claim an immediate loss deduction, which is not used solely as a tax offset. For many sole traders, understanding these rules is essential – not only to manage current tax liabilities but also to guide future business planning and growth strategies.
Deferred Non-Commercial Losses
If you are unable to claim your business losses in the current financial year, you may have the option to carry them forward for future use. When your business makes a profit in the next year, you can apply some or all of your deferred non-commercial losses against that profit up to the amount of the profit. You can also claim deferred losses against other income in a later year if:
- You meet the ATO’s non-commercial loss criteria, and
- The Commissioner allows you to apply the losses.
Carry Losses Forward Indefinitely
There is no set time limit on how long you can carry your losses forward. You can carry forward losses indefinitely as long as one of these conditions applies:
- Your business makes a profit, allowing you to offset the losses carried forward against those profits,
- You meet the conditions for non-commercial losses, or
- The Commissioner authorises the losses to be offset.
Advantages And Challenges of Carrying Forward Non-Commercial Losses
There are both advantages and disadvantages to carrying back non-commercial losses. On the positive side, it allows you to carry forward losses indefinitely until your business becomes profitable, providing potential tax relief in future years. This approach can be beneficial when your business generates enough profit to absorb those accumulated losses.
However, it also poses some challenges. It can be difficult to meet the ATO’s strict requirements, and claims can be rejected if your business is not truly commercial. It is essential to keep detailed financial records and a clear, profit-focused business plan to demonstrate the purpose of your business.
Additionally, if you receive income from other sources or have other tax losses, combining these with deferred non-business losses can complicate your tax situation. This makes regular tax planning and professional guidance important for proper compliance and management.

Four Non-Business Loss Tests
Meeting the income and business activity requirements alone does not automatically qualify you for non-business loss reimbursement. You must also meet at least one of the four non-business loss tests:
Assessable Income Test: Your business must have earned at least $20,000 in assessable income, including gross earnings and capital gains. If your business has been in operation for less than a year, you can make a reasonable estimate of income for the entire year.
Profit Test: If your business has been in operation for more than five years, it must have reported a profit in at least three of those years, including the current one.
Real Estate Test: You meet this test if your business uses real estate worth $500,000 or more. This includes land, leasehold interests, and fixed buildings, but does not include private residences and fixtures owned by tenants.
Other Asset Test: If you have at least $100,000 worth of business assets (excluding real estate and vehicles) that are used in your business on an ongoing basis, you are eligible. This may include plant and equipment, trademarks, inventory or leased assets.
Key Points
- A non-trading loss is when your business incurs losses that cannot be immediately offset against other income.
- As a sole proprietor, you can defer these losses indefinitely until your business makes a profit.
- To use a deferred loss, you must either make a profit, comply with the non-trading loss rules, or seek the Commissioner’s discretion.
- Keeping accurate financial records, evaluating your business strategy and seeking advice from tax experts can help you optimise the management of deferred losses.
- Stay informed through government platforms such as the ATO and ASIC for current tax laws and compliance updates.
