What is the tax free threshold and how does it work?
The tax free threshold is the amount of income you can earn before you owe income tax. In Australia, that figure is $18,200, based on the ATO’s individual income tax rates. Every dollar below this point is tax-free for income tax purposes. Above it, only the income above the threshold is taxed at the applicable rate.
The scale matters. Around **3.5 million individuals reported income consistent with sole trader activity in ATO taxation statistics. If you are working under an ABN, freelancing, contracting, or building a business on the side, the tax free threshold for sole trader income can affect how much you keep.
This is where many sole traders go wrong. Some over-claim, some under-claim, and some miss related sole trader income tax obligations entirely. If payroll is part of your setup, Payroller’s guide to payroll for sole traders is a practical place to start.
How the $18,200 threshold is structured
The rule here is simple: the tax-free threshold Australia** uses applies to individuals, not business names. If your taxable income sits below the threshold, your income tax bill is generally nil.
Once you earn above the threshold, income tax applies only to the portion above it. You do not lose the whole threshold when your income rises. That means earning slightly above the threshold does not make all your income taxable.
How the low income tax offset extends your effective tax-free income
The low income tax offset, often called LITO, can reduce the income tax you owe after the tax-free threshold has been applied. The ATO’s low income tax offset details set out how LITO works, including the maximum offset and phase-out range.
In plain English, a sole trader with taxable income around $20,000 may pay no income tax once LITO is calculated. But LITO is applied through your income tax return. You do not tick a separate box during the year as a sole trader.
Who is eligible to access the tax free threshold
Australian residents for tax purposes can usually access the threshold. For sole traders, eligibility depends on your individual tax status, not whether your business made a profit.
If you are unsure where you sit, start with your residency status, your total taxable income, and whether you operated as a sole trader during the financial year.
How does the tax free threshold apply differently to sole traders?
The tax free threshold applies to individuals, not to business structures. Because a sole trader and the individual are the same legal entity, the threshold applies to your net business income after expenses, not your gross revenue. That distinction matters. A sole trader may receive more than the threshold in payments, yet still have taxable income below it after legitimate business deductions.
Why sole traders are taxed as individuals, not businesses
As a sole trader, you do not lodge a separate company tax return for the business. You report your business income in your individual income tax return.
Your ABN identifies your business activity, but it does not create a separate taxpayer. If you are still setting up your business identity, this guide to setting up as a sole trader with an ABN explains the basics.
This is why the tax-free threshold Australia uses applies to you personally. Your business name, trading name, or ABN does not get its own threshold.
Gross revenue versus taxable income for sole traders
Gross revenue is the money your business receives before expenses. Taxable income is what remains after allowable deductions.
Example:
- You earn $30,000 in sole trader revenue
- You claim $15,000 in legitimate business deductions
- Your taxable business income is $15,000
- Your income tax on that amount may be nil
That is very different from an employee earning the same gross amount. Employees cannot reduce taxable income in the same way simply by incurring business operating costs.
How multiple income sources affect your threshold entitlement
All assessable income is combined before the threshold applies. If you run a business and also work a part-time job, both income streams count.
This also includes personal services income, freelance income, bank interest, and investment income. Your sole trader income tax position depends on the total picture, not just the money paid into your business account.
Can a sole trader claim the tax free threshold, and how?
Yes, a sole trader can claim the tax free threshold, but the process looks different from an employee’s. An employee claims it by ticking a box on a Tax File Number declaration form with their employer. A sole trader has no employer to submit that form to, so the threshold is applied when they lodge their annual income tax return.
How the threshold is applied when lodging a sole trader tax return
Your tax-free threshold claim happens through your tax return. You declare all assessable income, claim eligible deductions, and the ATO applies the threshold and any tax offsets to your final taxable income.
You do not submit a TFN declaration to yourself. There is no payroll form for your own sole trader earnings.
What documentation you need before lodging
Clean records make lodgement easier and reduce the chance of missed income or overstated deductions.
Keep these records ready:
- Income records from invoices, receipts, and payment platforms
- Expense receipts and supplier bills
- Bank statements for business transactions
- BAS records if registered for GST
- Payroll records if you employ staff
- Records of any tax withheld from employment income
Your income tax return should show the full financial year, not just what sits in your account at tax time.
Common mistakes when claiming the threshold as a sole trader
The most common mistake is treating business income in isolation. If you earned wages, casual pay, investment income, or freelance income under another ABN, it still feeds into your taxable income.
Other mistakes include:
- Claiming private expenses as business deductions
- Forgetting bank interest or dividends
- Treating GST collected as business income
- Assuming no tax payable means no lodgement obligation
If you want to avoid repeat errors, Payroller’s guide to common small business tax mistakes gives practical examples.
Do sole traders still need to lodge a tax return below $18,200?
Often, yes. Even if your taxable income is below $18,200, lodgement may still be required. The ATO may require an income tax return if you ran a business during the financial year, had tax withheld from income, or have another tax liability. The ATO’s lodgement requirements explain when you need to lodge.
When lodgement is mandatory regardless of income
If you operated as a sole trader at any point during the financial year, the ATO generally expects you to lodge. That applies even if your business made little or no profit.
You may also need to lodge if:
- Tax was withheld from wages or other payments
- You are entitled to a refund
- You had reportable fringe benefits or other assessable income
- You have a Medicare levy liability
How running a business triggers a lodgement obligation
Sole trader tax obligations are wider than income tax payable. Running a business means the ATO needs your income, expenses, and net income reported through your return.
If you held an ABN but did not trade, your position may differ from someone who actively issued invoices or received business payments. The cleanest approach is to keep records that show exactly what happened during the year.
What happens if you do not lodge when required
If you do not lodge when required, the ATO can issue failure-to-lodge penalties. You may also delay refunds from tax withheld through employment or other income.
Lodgement is not only about paying tax. It is also how the ATO calculates offsets, refunds, Medicare levy outcomes, and future PAYG instalments.
What other taxes apply near the tax free threshold?
The tax free threshold only applies to income tax. It does not remove Medicare levy, GST, or PAYG obligations. A sole trader may have no income tax after offsets yet still face another payment or reporting requirement. The most common near-threshold issue is the Medicare levy, which can apply based on taxable income and personal circumstances.
How the Medicare levy applies to sole traders near the threshold
The Medicare levy is separate from income tax. The ATO’s Medicare levy guidance explains the levy rate and low-income thresholds.
For example, a sole trader on $22,000 may have no income tax after LITO but still need to factor in Medicare levy exposure. That can surprise people who focus only on the tax-free threshold and ignore the rest of the assessment.
PAYG instalments and when they kick in
**PAYG instalments are prepayments toward your expected tax bill. The ATO decides whether you enter the system based on your prior tax position.
You do not opt into PAYG instalments simply because you are a sole trader. Once you are in the system, the payments can help smooth cash flow instead of leaving your full tax bill until lodgement.
GST registration and its independence from income tax thresholds
GST works separately from income tax. Registration is based on turnover, not taxable income after deductions.
This matters because a sole trader can sit below the income tax threshold yet still need to track GST if their turnover reaches the registration threshold. GST collected from customers should be kept separate from your own income planning because it belongs to the ATO.
What income counts toward the tax free threshold for sole traders?
All assessable income** counts, not just business income. That includes money earned from employment, rental income, investment returns, government payments, and other taxable income sources alongside your sole trader business. Everything is pooled into a single taxable income figure before the threshold, deductions, and offsets are applied.
Types of assessable income a sole trader must declare
Your income tax return needs to include all taxable income sources. Common examples include:
- Sole trader business income
- Salary or wages
- Casual employment income
- Bank interest
- Dividends
- Rental income
- Government payments that are taxable
- Freelance or contracting income
- Personal services income
If you receive income through different accounts or platforms, it still counts. The ATO’s data-matching systems make unreported income easier to detect.
How deductions reduce taxable income toward the threshold
Business deductions reduce taxable income, not gross income. This is one of the most useful concepts for sole traders near the threshold.
Say you earn $25,000 in business revenue and claim $10,000 in legitimate deductions. Your taxable income from the business becomes $15,000 before adding any other income sources.
If you want the wider rate picture once your income exceeds the threshold, Payroller’s guide to individual income tax brackets in Australia is a useful next read.
Income sources sole traders commonly forget to include
The most commonly missed items are small, irregular, or paid outside the main business bank account.
Watch for:
- Interest on savings accounts
- Dividends from shares
- One-off freelance work
- Payments through online marketplaces
- Income earned under another business name
- Taxable government payments
- Tips, bonuses, or referral payments
GST collected from clients is different. It is not income you keep, so it should not inflate your taxable income calculation.
How can sole traders optimize their tax position around the threshold?
The most effective strategy is maximizing legitimate deductions so your taxable income stays as close to the threshold as possible, where the facts support it. This is about timing, record-keeping, and knowing which expenses genuinely relate to earning income. Payroller helps by giving you cleaner income and payroll records during the year, not just after the year ends.
Timing income and expenses to manage taxable income
Timing can affect which financial year income or expenses fall into. If you are close to the LITO phase-out range, timing an invoice or paying a deductible expense before year-end may affect your final tax position.
Keep it practical and ethical:
- Invoice when work is complete and payment terms make sense
- Record income when it is earned or received according to your reporting method
- Pay genuine business expenses when they are needed
- Avoid buying items only for a tax deduction if they do not help the business
Good timing is planning. Poor timing is guesswork.
Deductions sole traders most commonly miss
Sole traders often miss deductions because they do not track small expenses during the year. Those small amounts can add up.
Common deductions include:
- Home office running costs
- Motor vehicle use for business travel
- Professional subscriptions
- Business insurance
- Accounting and bookkeeping fees
- Software subscriptions
- Equipment and tools
- Training related to your current business activity
- Phone and internet use for business
The rule is direct: the expense must relate to earning your assessable income. If it has both business and private use, claim only the business portion.
Using offsets and concessions available to low-income sole traders
The low income tax offset can reduce your income tax after your taxable income is calculated. Sole traders may also access the small business income tax offset, also known as the unincorporated small business tax offset. It applies to tax attributable to business income and is capped annually.
This is where real-time records help. If you only calculate net income after the financial year closes, you lose the chance to make informed choices before lodgement.
Payroller supports that habit by helping you track income records, payroll, and PAYG amounts in one place. It gives you a clearer view of where you stand before tax time, without relying on manual spreadsheets.
What are the most common tax mistakes sole traders make around the threshold?
The most frequent mistake is treating the $18,200 threshold as a clean “earn this and you owe nothing” rule. In practice, related sole trader tax obligations can still apply. Lodgement, Medicare levy, PAYG instalments, deductions, and combined income from multiple sources can all change the final outcome.
Assuming no tax means no lodgement obligation
No income tax payable does not automatically mean no income tax return. If you ran a business, had tax withheld, or triggered another reporting requirement, you may still need to lodge.
This is where many new sole traders get caught. They focus on the threshold and forget the reporting side.
Forgetting to include all income sources
A common scenario looks like this:
- You earn $16,000 from your sole trader business
- You also earn $5,000 from casual employment
- Your combined income is $21,000
- You are above the threshold before deductions and offsets are assessed
If you only looked at the business income, you would make the wrong call.
Miscalculating the threshold after deductions versus before
The threshold applies to taxable income, not gross revenue. That works in your favor when you have valid business expenses.
The reverse can also hurt you. If you forget to claim deductions, you may report higher taxable income than necessary. If you over-claim, the ATO can question the return and ask for records.
