A business loss can be frustrating, particularly when you have invested real time, money and effort into building an income-producing activity. For Australian sole traders and partners, the key question is often whether that loss can reduce other income, such as salary, wages or investment income, in the same tax return.
The answer is not always straightforward. Australia’s non-commercial loss rules can prevent a business loss from being offset immediately, even where the underlying expenses would otherwise be deductible. Understanding the rules early can help you prepare accurate records, avoid an unexpected adjustment at tax time and make better decisions about cash flow and business structure.
Start with the distinction between a deduction and an immediately usable loss
A deductible business expense and a loss you can offset against other income are related, but they are not the same thing.
A sole trader may incur legitimate expenses in carrying on a business, such as stock costs, advertising, insurance, professional fees, rent, software subscriptions or the business portion of vehicle and home office costs. Those expenses still need to satisfy the ordinary deduction rules and be properly substantiated.
However, if deductions from a particular business activity exceed its assessable income, the activity has made a tax loss for the year. The non-commercial loss rules then determine whether that loss can be used immediately against the individual’s other assessable income.
These rules generally apply to individuals carrying on a business:
- as a sole trader
- as a partner in a partnership
- through one or more separate business activities.
They are designed to limit the immediate use of losses from activities that do not yet show sufficient commercial characteristics under the relevant tests.
This does not mean every loss-making activity is a hobby, and it does not mean the expenses are automatically private or non-deductible. It means the timing of the tax benefit may be restricted.
A company’s tax losses are subject to a different set of rules. Trust structures can also require separate analysis. If you operate through a company, trust or a combination of entities, it is important not to assume the individual non-commercial loss rules apply in the same way.
Confirm that you are genuinely carrying on a business
Before applying the non-commercial loss rules, it is necessary to establish that the activity is actually a business.
An activity can be small, new or temporarily unprofitable and still be a business. Equally, having an ABN, a separate bank account or a social media page does not, on its own, prove that a business is being carried on.
The overall facts matter. Relevant practical indicators often include whether the activity is conducted in a businesslike way, whether there is a genuine purpose of making a profit, the scale and repetition of transactions, the level of planning and record-keeping, and whether the activity resembles similar commercial operations.
For example, a graphic designer who actively markets services, issues invoices, enters client contracts, maintains business records and seeks regular paid work may be carrying on a business even if the first year produces a loss. By contrast, occasional sales from a personal hobby may not have developed into a business for tax purposes.
This distinction matters because hobby expenses are not deductible merely because the hobby produces some income. The non-commercial loss rules only become relevant after an activity is properly characterised as a business activity.
It is also important to identify the activity accurately. A taxpayer may operate more than one activity, and a loss from one should not automatically be blended with income from another simply because both are conducted under the same ABN.
In some situations, similar business activities may be grouped when applying the rules. Whether activities are sufficiently similar depends on the facts, including their nature, the products or services offered, customers, operations and commercial relationship. This is an area where careful advice can be valuable.
The income requirement and the four commercial tests
For many sole traders and partners, the first gateway is the income requirement.
The requirement looks at the combined total of the individual’s taxable income, reportable fringe benefits, reportable superannuation contributions and total net investment losses. The relevant total must be less than $250,000 for the individual to access the standard commercial tests.
If the income requirement is met, the business activity only needs to satisfy one of four tests for the loss to be available against other income in that year.
The assessable income test
This test is met where the business activity produces at least $20,000 of assessable income for the income year.
Where an activity began or ceased during the year, a reasonable full-year estimate may be relevant. This can assist a new or discontinued activity, but it is not a licence to use unrealistic projections. The estimate needs to be reasonable in the circumstances.
For many service businesses, this is the most practical test. A consultant, tradesperson, online retailer or freelancer may have deductible start-up and operating costs that exceed income in an early year, while still generating enough assessable income to satisfy this test.
The profits test
The profits test focuses on the activity’s track record. Broadly, it is met where the activity has made a tax profit in at least three of the past five income years, including the current year.
A tax profit is not necessarily the same as a cash surplus. Tax calculations can be affected by timing differences, depreciation deductions, stock movements and other tax adjustments. It is therefore worth reviewing the tax results rather than relying only on management accounts or bank balances.
This test can be especially useful for businesses with an occasional poor year after an established history of profitability.
The real property test
The real property test looks at real property, or interests in real property, used on a continuing basis in the business activity. The relevant value must be at least $500,000.
The law allows the market value of the property to be used where it exceeds the reduced cost base. However, a dwelling and associated land used mainly for private purposes are excluded, as are fixtures owned by a tenant.
This test is more likely to be relevant to some primary production, property-intensive or land-based businesses than to professional service businesses.
The other assets test
The other assets test is met where the value of certain assets used on a continuing basis in the activity is at least $100,000.
Assets that may count include depreciating assets, trading stock, qualifying leased assets and certain intellectual property rights. The relevant value depends on the type of asset. For example, depreciating assets are generally considered using their written-down value rather than their original purchase price.
Not every business asset counts. Cars, motorcycles and similar vehicles are specifically excluded from this test. Real property considered under the real property test is also not counted again here.
Where an asset is used partly for the business activity and partly for another purpose, only the relevant business-use portion is considered.
When an exception or the Commissioner’s discretion may help
Some businesses do not need to satisfy the income requirement and one of the four tests.
An exception may apply where the activity is a primary production business or a professional arts business, and the individual’s assessable income from unrelated sources, excluding any net capital gain, is less than $40,000.
Professional arts businesses are defined narrowly. They include businesses carried on by authors of literary, dramatic, musical or artistic works, performing artists and production associates. The exception should not be assumed simply because a person works in a creative field.
Where the exception does not apply and the business activity does not meet the ordinary pathway, the Commissioner of Taxation has a discretion that may allow the loss to be claimed in the current year.
The discretion is not automatic. It is intended for limited circumstances, including:
- special circumstances outside the operators’ control, such as drought, flood, bushfire or another natural disaster
- a genuine lead time inherent in the nature of the business activity
- an activity that has a commercially viable path to meeting a test or producing a tax profit, supported by objective evidence.
For special circumstances, it is not enough that conditions were difficult or that the business simply performed below expectations. The circumstances need to be outside the operators’ control and sufficiently connected to the activity failing a test or making a profit.
For lead-time businesses, the issue is the inherent nature of the activity, not the fact that the business started small, lacked working capital or took time to build a customer base. Independent industry evidence, forecasts, contracts, production data and expert material may be important.
An application is required for the Commissioner’s discretion. It should be prepared carefully, with evidence that directly addresses the legal basis for the request. A well-organised submission is generally far more persuasive than a broad statement that the business is expected to become profitable.
What happens when a loss is deferred?
A deferred non-commercial loss is not necessarily lost forever.
Instead, the excess deductions are treated as available in a later year when the same activity continues. The deferred amount can generally be applied against future assessable income from that activity. It may also become available against other income in a later year if the activity then meets the applicable requirements or the Commissioner exercises the discretion.
This is why accurate tracking matters. Deferred losses should be recorded separately for each relevant business activity, rather than being treated as one general pool of losses.
Consider a sole trader who runs a small specialty food business while also working part-time as an employee. The business has deductible operating costs and produces a tax loss in its first year. The owner meets the income requirement but does not satisfy any of the four tests, and there are no grounds for the Commissioner’s discretion.
The owner cannot use that business loss to reduce employment income in that year. The loss is deferred. If the food business grows and later satisfies a test or produces sufficient income, the deferred amount may be available in accordance with the rules applying in that later year.
The immediate tax outcome may be disappointing, but it does not alter the need to claim legitimate expenses correctly, maintain supporting documents or monitor the activity’s commercial progress.
Practical steps to prepare with confidence
Non-commercial loss issues are easier to manage when they are considered before lodgment, rather than after the tax return has been prepared.
A sensible annual review should include the following steps:
Identify each business activity separately.
Consider whether activities are genuinely separate or whether similar activities may be grouped.
Confirm the activity is a business, not a hobby.
Keep evidence of business planning, marketing, contracts, invoices, pricing, customer engagement and the intention to make a profit.
Calculate the tax result for the activity.
Do not rely solely on cash flow. Include tax adjustments, depreciation, stock movements and any relevant apportionment of shared costs.
Check the income requirement.
Include all components that form part of the required calculation, not just taxable income.
Test the activity against each commercial test.
The assessable income test is often the first place to start, but the profits, real property and other assets tests should not be overlooked.
Review whether an exception applies.
This can be particularly relevant for eligible primary production and professional arts activities.
Consider the Commissioner’s discretion early.
If special circumstances or an inherent lead time may be relevant, gather independent evidence while it is available.
Maintain a deferred-loss schedule.
Record the amount deferred, the business activity it relates to and how it is treated in later income years.
Good bookkeeping is central to this process. Clear income and expense coding, reconciled bank accounts, supporting invoices, asset registers and year-end reports make it easier to calculate the result properly and respond if the ATO requests information.
The key takeaway
A business loss does not automatically reduce your salary, investment income or other personal income in the year it arises. For sole traders and partners, the non-commercial loss rules can affect when a tax deduction delivers a benefit, rather than whether the underlying business expense is valid.
The best approach is to assess the rules alongside your annual tax planning, keep reliable records and avoid making assumptions based only on cash flow or turnover. If your activity is new, seasonal, asset-intensive or affected by events outside your control, tailored advice can make a meaningful difference to how the rules are applied.
