The big question for any business owner in Australia—sole trader or company—really boils down to one thing: how your profits are taxed. As a sole trader, every dollar you earn is taxed at your personal marginal rate. As your business grows, so does your tax bill. In contrast, a company pays a flat corporate tax rate, which can be a game-changer for reinvesting profits and scaling up.

Choosing Your Business Structure: Key Tax Differences
Deciding to operate as a sole trader versus a company is one of the most important financial calls you'll make. It directly shapes your tax bill, how protected your personal assets are, and your capacity to grow. The simplicity of being a sole trader is tempting, but the tax realities are worlds apart from a company structure.
Let's cut through the noise and focus on what really hits your bottom line: the tax treatment of your profits.
Tax Treatment: As a sole trader, your business profit is your personal income, so it's taxed at ever-increasing individual rates. Company profits are taxed at a flat corporate rate (25% for most small companies), which is lower than the personal rates on higher profits, creating a clear advantage for keeping more money in the business to fuel growth.
Legal Liability: When you're a sole trader, there's no legal distinction between you and the business. Your personal assets—your house, your car—are on the line. A company is a separate legal entity, which acts as a shield to protect your personal wealth from business debts.
Administrative Burden: Sole traders have it easy here with minimal setup and compliance. Companies demand formal registration with ASIC, annual reviews, and much more rigorous record-keeping. It's more work, no doubt about it.
It's a classic balancing act. The sole trader route offers simplicity but comes with high personal risk. A company provides that crucial legal protection but at the cost of more admin.
The core decision hinges on balancing immediate simplicity against long-term financial efficiency and legal protection. As your business grows, the tax benefits of a company structure often become too significant to ignore.
For sole traders, the tax pain kicks in as you become more successful. At 2025–26 rates, a sole trader with $180,000 of profit pays about 28% of it in tax overall (including the Medicare levy, after the small business income tax offset), and 39% on each extra dollar. A company with the same profit (as a base rate entity) is taxed at a flat 25% on the profit it keeps, although you pay top-up tax when profits are paid out to you as dividends. That gap widens as profit grows, which is why the structure question matters for growing businesses.
The biggest financial question when comparing a sole trader to a company comes down to one thing: how each dollar of profit gets taxed. This isn't just a small detail on a tax form; it's the core difference that could save—or cost—you thousands over the life of your business. The structure you choose directly dictates how much cash stays in your pocket and how much you can reinvest.
For a sole trader, the maths is simple. Your business profit is your personal income. It gets lumped in with any other income you earn and is taxed at your marginal personal income tax rate. As your business grows and your profits climb, you inevitably get pushed into higher tax brackets, meaning the ATO takes a bigger slice of every new dollar you make.
A company, however, is a completely separate legal and tax entity. It pays tax on its profits at a flat corporate rate, which for most small businesses in Australia is 25%. That base rate entity rate applies if the company's aggregated turnover is under $50 million and no more than 80% of its assessable income is passive income (such as interest, rent, dividends and net capital gains); otherwise the rate is 30%, so a company that mainly holds investments pays 30%. This separation is what creates a clear tax advantage, especially for businesses that want to keep profits in the tank to fund future growth.
A Real-World Profit Scenario
Let's make this tangible. Imagine you're a skilled plumber in Sydney having a great year, clearing $80,000 in profit, with no other income. As a sole trader, that entire $80,000 lands on your personal tax return. At 2025–26 rates, income tax plus the 2% Medicare levy comes to $16,388. Because your turnover is under $5 million, the small business income tax offset (16% of the tax on your business income, capped at $1,000) brings that down to about $15,388. In 2026–27, when the 16% tax rate drops to 15%, the same profit costs about $15,120.
Now, let's see what happens if that same business is structured as a company. The $80,000 profit is taxed at the flat 25% base rate entity rate, resulting in a $20,000 tax bill, so at this profit level the company actually pays more tax than the sole trader. The crucial part is what happens next. The company now holds the remaining $60,000. That money can be used to buy new equipment, hire staff, or invest in marketing—all without you personally paying any more tax on it until it's paid out to you. (In practice you'd also pay yourself a salary, which is deductible to the company and taxed in your hands.)
Here's the key takeaway: As a sole trader, every dollar of profit is taxed at your personal rate, straight away. With a company, profits left inside the business are taxed at the flat corporate rate, and you pay personal tax only on what you take out as salary or dividends (with a credit for the company tax already paid on franked dividends).
Tax Liability At Different Income Levels
This difference in tax treatment becomes much more dramatic as your income rises. Because personal tax rates are progressive, a sole trader's tax burden accelerates far more quickly than a company's. For a closer look at how the brackets work, check out our detailed guide on Australian sole trader tax rates.
To really see the impact, let's run the numbers and compare the tax payable at different profit levels. This shows the potential savings a company offers if you plan on retaining profits in the business.
Tax Liability Comparison: Sole Trader vs Company
This list breaks down the tax payable for each structure at 2025–26 rates (2026–27 in brackets), assuming the profit is your only income, the sole trader claims the full $1,000 small business income tax offset, and the company is a base rate entity that keeps all its after-tax profit in the business.
$80,000 profit: sole trader about $15,388 ($15,120) including the Medicare levy; company $20,000. The sole trader pays about $4,612 less.
$150,000 profit: sole trader about $38,838 ($38,570); company $37,500. The company pays about $1,338 less.
$250,000 profit: sole trader about $82,638 ($82,370); company $62,500. The company pays about $20,138 less.
The numbers tell a clear story. If all the profit stays in the company, the company structure only pulls ahead once profit passes roughly $140,000 (2025–26 rates, after the offset). The sharper comparison is at the margin: a sole trader pays 32% (30% plus the Medicare levy) on each dollar of profit from $45,001 to $135,000 and 39% from $135,001 to $190,000, against 25% in a company. So the more profit you can leave in the business to reinvest, the bigger the saving. For any business owner focused on scaling up, this is a critical point to be aware of.
What Happens When You Take the Profits Out
The company rate isn't the end of the story. When the company pays you a dividend out of taxed profits, it can attach franking credits for the 25% tax it has paid. You include the dividend plus the franking credit in your taxable income, pay tax at your marginal rate and get a credit for the company tax. If your marginal rate is higher than 25% you pay top-up tax; if it's lower, the excess credit is refunded. For example, if the company in the $80,000 scenario pays out all $60,000 as a fully franked dividend and you have no other income, you declare $80,000 ($60,000 plus the $20,000 franking credit). Your tax and Medicare levy at 2025–26 rates is $16,388, so the $20,000 credit leaves a $3,612 refund, and the total tax is the same as a sole trader pays before the small business income tax offset (which companies can't claim). In other words, the company saving comes mainly from profits you leave in the business, not from money you take home. See our guide to franking credits.
Navigating Deductions And Business Expenses
On the surface, both sole traders and companies can claim deductions for legitimate business costs. But that’s where the similarities end. The real story behind the tax benefits of a company versus a sole trader emerges when you dig into the strategic planning opportunities a company structure unlocks.
Sure, both can deduct everyday expenses like rent, supplies, and marketing. However, the company’s status as a separate legal entity opens up powerful avenues for reducing taxable profit that a sole trader simply can't access.
When you're weighing up these structures, understanding how to properly claim everything you're entitled to is essential. For sole traders, knowing the full scope of available small business tax deductions can make a huge difference to your final tax bill, ensuring nothing gets missed.
The game changes with a company, though, as it introduces deductions that are completely off the table for a sole trader.
Strategic Deductions for Companies
A massive advantage for a proprietary limited company is its ability to pay its owners (who are also directors) a salary, superannuation, and even director's fees. These aren't just drawings; they are treated as legitimate business expenses.
This directly reduces the company's taxable profit before the 25% corporate tax rate is even applied.
For example, paying yourself a director's salary provides a steady personal income while simultaneously lowering the company's tax bill. On top of that, the compulsory superannuation contributions paid on that salary are also a deductible expense for the business. It’s a tax-efficient way to pull money out of the business while building your own retirement nest egg. The salary is taxed in your hands at your marginal rates, so the aim is to balance salary against profit retained in the company. (Sole traders aren't locked out of super either: they can claim a deduction for personal super contributions within the concessional cap, $30,000 for 2025–26 and $32,500 from 1 July 2026.)
The ability to treat owner remuneration and superannuation as deductible business expenses is a fundamental tax benefit of the company structure. It allows you to strategically lower company profit while building personal wealth in a tax-effective manner.
The Personal Services Income Trap
Both structures run into the same wall if most of your income is a reward for your personal skills or effort, for example a contractor billing one client by the hour: the Personal Services Income (PSI) rules. If you don't pass the results test or another personal services business test, the PSI rules apply whether you're a sole trader or work through a company. A company can't keep that income at the 25% rate: it must pay it to you as salary, or it's attributed to you and taxed at your marginal rates. You also can't deduct rent, mortgage interest, rates or land tax for your home, or payments to an associate (such as your spouse) for non-principal work, including super for that work. Read more about personal services income.
A company structure does force a clearer separation between business and personal finances, which tends to make record-keeping cleaner. But the company's money isn't yours. If you take money out other than as salary, director's fees or dividends (for example a loan, or the company paying your personal bills), Division 7A can treat it as an unfranked dividend taxed at your marginal rate, unless it's repaid or put under a complying loan agreement by the company's lodgement day (the benchmark interest rate is 8.77% for 2026–27). See our guide to Division 7A loans.
Comparing Asset Protection And Legal Liability
While the tax benefits are a massive part of the sole trader vs company debate, we can't stop there. For a lot of business owners I speak to, this next point is actually more important than saving a few dollars on tax. It's about personal liability, and it hits right at your financial security and peace of mind, especially as your business starts to grow and take on bigger risks.
As a sole trader, the law sees absolutely no difference between you and your business. You are one and the same. This means if your business gets into financial strife or someone decides to sue you, your personal assets are fair game. We're talking about your family home, your car, your savings – it's all on the line to settle business debts.
This complete lack of separation is hands down the single biggest risk of being a sole trader. If you're in an industry with a higher chance of things going wrong, like construction or professional consulting, this unlimited liability can be a constant source of stress.
The Company's Corporate Veil
Now, flip the coin. A company is a separate legal entity. This isn't just fancy legal talk; it creates a genuine barrier, often called the 'corporate veil', that stands between the business's finances and your personal finances. It's one of the most powerful reasons to incorporate, completely separate from any tax advantages.
What this legal wall means is that if the company racks up debt or gets sued, the liability is generally capped at the assets the company itself owns. Creditors can go after the business bank account or its equipment, but your personal assets are safely tucked away on the other side of that veil.
The corporate veil is your personal financial shield. It means a business failure doesn't have to become a personal financial catastrophe, giving you the confidence to take calculated risks and grow your venture.
Where Limited Liability Stops
Personal guarantees: banks, landlords and suppliers often ask small company directors to guarantee the company's debts personally, so you're liable for those debts anyway.
Director penalties: directors can be made personally liable for the company's unpaid PAYG withholding, GST and super guarantee charge under the ATO's director penalty regime.
Insolvent trading: directors can be personally liable for debts the company incurs while it's insolvent.
Breaches of director duties: directors have legal duties under the Corporations Act 2001 and can face penalties and compensation claims if they breach them.
Your own actions: the company doesn't protect you from liability for your own negligence or fraud.
A Practical Liability Scenario
Let's make this real. Imagine a business lawsuit goes badly and results in a $100,000 liability.
Sole Trader Outcome: The business only has $30,000 in assets. The creditors can, and will, legally come after the owner for the remaining $70,000. This could mean being forced to sell your car or, in the worst case, bankruptcy and losing your family home.
Company Director Outcome: The company has the same $30,000 in assets. The creditors can only claim that $30,000. Assuming the director has acted lawfully and hasn't given a personal guarantee, they are not personally on the hook for the $70,000 shortfall. Directors can still be personally liable for insolvent trading and, under the ATO's director penalty regime, for the company's unpaid PAYG withholding, GST and super guarantee charge.
This stark difference shows exactly why asset protection is a critical piece of the sole trader vs company tax benefits conversation. The legal shield a company provides is often invaluable, laying a much safer foundation for long-term, sustainable growth.
Understanding Compliance Costs And Administration
Beyond the tax rates themselves, the day-to-day admin is a huge factor that hits your two most valuable resources: your time and your money. For many new ventures, the sheer simplicity of being a sole trader is its biggest selling point. The setup is dead simple—often just an Australian Business Number (ABN)—and the ongoing compliance is just as straightforward, usually just rolling everything into your personal tax return.
A company, on the other hand, is a completely different beast when it comes to admin. Getting started means a formal registration with the Australian Securities and Investments Commission (ASIC), which costs $636 for a proprietary company (from 1 July 2026). And that’s really just the first step on a much more demanding compliance journey.
The Ongoing Demands Of A Company
Running a company means committing to a whole host of ongoing regulatory requirements. These aren't just 'nice-to-haves'; they're legal obligations, and ignoring them comes with hefty penalties. The administrative price tag you pay for the tax and liability benefits is significantly higher.
Here’s a taste of the key ongoing obligations you’re signing up for:
Annual ASIC Review: Every year, you have to pay an annual review fee just to keep your company registered.
Separate Tax Returns: You’ll need to prepare and lodge a separate, more complex company tax return each year. We break this down in our guide on how to lodge a company tax return.
Stricter Record-Keeping: Corporate law demands that you keep meticulous financial records. This isn't just about receipts; it includes formal minutes of meetings and resolutions from the director.
All this extra work almost always translates into higher fees from your accountant. On top of that, ASIC charges an annual review fee of $342 for a proprietary company (from 1 July 2026), and the company needs its own tax return and financial statements each year. For many growing businesses the tax savings and asset protection make the trade-off worth it, but it's worth costing out before you switch.
It all boils down to a fundamental trade-off: Do the potential tax savings and asset protection a company offers actually outweigh the extra costs and administrative headaches? This is exactly where getting professional advice is non-negotiable for making a smart financial decision.
Ultimately, the right choice really depends on the scale of your business, your risk profile, and where you see it going. A sole trader structure is perfect for low-risk, simple operations where keeping costs and complexity down is the number one priority. A company is built for businesses with big growth plans, those who need to protect their personal assets, and are ready to take on the administrative load that comes with it.
Ownership, Raising Capital and Selling
Ownership: a sole trader business belongs to one person. If you want to bring in a partner, you have to change structure (for example to a partnership or a company). A company can have several shareholders, each owning a set number of shares, ideally with a shareholders agreement covering who decides what.
Raising capital: a sole trader can only fund the business with their own money or personal borrowing. A company can also issue new shares to investors without changing the business itself.
Selling or passing on the business: a sole trader sells the business by selling its assets, and the business ends when they stop trading or die. A company carries on regardless of who owns it, so it can be sold by transferring the shares, and the business doesn't end when an owner leaves.
What Happens When You Close the Business?
A sole trader can stop trading at any time: you lodge your final BAS and tax return, cancel your ABN and GST registration, and you remain personally responsible for any debts the business still owes. A company has to be formally ended. If it's solvent, has no liabilities, has assets worth less than $1,000, isn't carrying on business and all members agree, the directors can apply to ASIC for voluntary deregistration. Otherwise it needs to be wound up by a liquidator. Directors remain liable for any director penalties even after the company is deregistered.
Making The Right Choice: When To Switch To a Company
Deciding when to jump from a sole trader to a company structure isn't just about tax; it’s a strategic pivot for your business's future. The beautiful simplicity of being a sole trader is perfect for getting off the ground, but there are clear signals that it’s time to evolve.
Ignoring these signs can mean handing over unnecessary tax to the ATO, putting your personal assets on the line, and artificially capping your growth potential.
This isn’t about hitting a single magic number. It's about a combination of factors reaching a tipping point. The key is spotting these triggers before they become problems, ensuring your business structure is a springboard for your long-term goals, not an anchor holding you back.
Key Triggers for Incorporation
Thinking about making the switch? Keep an eye out for these classic scenarios. If one or more of these sounds familiar, it’s a strong sign that a company structure is the next logical move.
Your Profit Is Hitting Higher Tax Brackets: From $45,001 a sole trader pays 32% (including the Medicare levy) on each extra dollar of profit, and from $135,001 it's 39%, compared with the flat 25% company rate. Once your profit consistently exceeds what you need to live on, leaving the surplus in a company can save real tax. This is the most common financial trigger we see.
You Need to Protect Your Personal Assets: As your business grows, so does its risk profile. If you've built up personal wealth—like a family home or an investment portfolio—the unlimited liability of a sole trader structure becomes a huge, unacceptable risk. A company creates a legal firewall.
You Want to Reinvest Profits Into the Business: A company is a far more tax-efficient vehicle for growth. It lets you keep post-tax profits (taxed at just 25%) in the business to fund expansion, buy assets, or hire staff, without that money first being hit at your higher personal tax rate.
The decision to incorporate is fundamentally a forward-looking one. It’s about building a foundation that can handle increased profit, greater risk, and future complexity, turning your successful operation into a scalable and protected enterprise.
You're Bringing on Partners or Investors: If the plan is to bring other people into the business, a company structure is usually the cleanest option. It provides a clear framework for issuing shares, defining ownership, and managing control in a way a sole trader setup simply can't.
Recognising these triggers is the first step; the next is taking action. If you're ready to look into this more deeply, our guide on how to set up a PTY LTD company in Australia lays out a clear roadmap for the incorporation process. Making this change at the right time is absolutely crucial for locking in the best possible financial outcomes.
Can a Sole Trader Hire Employees?
Yes, a sole trader can hire employees. You'll need to register for PAYG withholding with the ATO, report pay through Single Touch Payroll, pay super guarantee (12%) for eligible staff (from 1 July 2026, super must reach the employee's fund within 7 business days of payday under Payday Super), and take out workers compensation insurance in your state. However, this is where a sole trader's unlimited liability becomes a serious risk. Once you have employees, you're responsible for their safety at work and exposed to claims such as unfair dismissal or workplace injuries. Because there's no legal wall between you and the business, any liability from your role as an employer lands on you personally. This is one of the main reasons businesses incorporate before building a team: the company is the employer, so most employment-related claims are made against it rather than against your personal assets.
Changes from 1 July 2027: for capital gains that accrue from that date, the 50% CGT discount is replaced with cost base indexation and a minimum tax of 30% on certain gains. Gains that accrued before 1 July 2027 keep the 50% discount, and different rules apply to new residential builds. See the ATO's capital gains tax reform page.
Your Questions Answered
As a sole trader, you take 'drawings' from the business whenever you like. Drawings aren't deductible and don't change your tax, because you're taxed on the business profit itself. As a company director it's more formal. You can pay yourself a salary or director's fees, which are deductible to the company but bring you into the payroll system: PAYG withholding, Single Touch Payroll reporting and super guarantee (12%, paid with each pay under Payday Super from 1 July 2026). That income is taxed at your marginal rates. You can also pay yourself dividends out of after-tax profit, usually with franking credits for the company tax already paid. Taking money out any other way, such as a loan you don't repay, can be treated as an unfranked dividend under Division 7A.
If a sole trader sells a business asset at a profit, the capital gain is added to their personal income for the year. They can often use the 50% CGT discount if they've owned the asset for at least 12 months, halving the taxable gain. A company gets no such discount: the whole capital gain is taxed at the company rate (25% or 30%). Both structures can use the small business CGT concessions (the 15-year exemption, the 50% active asset reduction, the retirement exemption and the small business rollover) if they meet the basic conditions, such as aggregated turnover under $2 million or net assets of no more than $6 million. For a company the rules are stricter (for example, it needs a significant individual), and a gain paid out to shareholders is generally taxed again in their hands unless an exemption applies. This is definitely not a DIY calculation, so get professional advice before selling significant assets. For sole traders, the 50% discount is replaced by cost base indexation for gains that accrue from 1 July 2027 (see the 2027 CGT changes).
Making the jump isn't just paperwork; it's a formal process with real financial implications. You register a new company with ASIC (and get it its own TFN, ABN and, if needed, GST registration), then transfer your business assets, such as equipment, client lists and goodwill, from your name to the company. That transfer can trigger tax: moving assets can crystallise a capital gain, and stamp duty may apply in some states. Rollovers such as the small business restructure rollover (for businesses with turnover under $10 million) can defer the income tax consequences if the conditions are met. Because of this, get professional guidance so the transition is structured properly and you don't get hit with unexpected tax during the changeover.
The four main structures are sole trader, partnership, company, and trust. A sole trader is simplest and cheapest but offers no liability protection. A company provides limited liability at a flat tax rate but costs more to run. A trust offers tax flexibility and asset protection but is complex to administer. The right choice depends on income, risk profile, and growth plans.
Base rate entities (companies with aggregated turnover under $50 million and no more than 80% of their assessable income from passive sources such as interest, rent and dividends) pay 25%. All other companies pay 30%. Shareholders pay income tax on dividends, with franking credits offsetting the tax already paid at the company level.
Consider a company when the business consistently makes more profit than you need to live on, so you can leave the surplus in the company at 25% instead of paying 32% to 47% on it personally (including the Medicare levy); when you need protection from business creditors; when you plan to bring in investors; or when you want to reinvest earnings. If all the profit stays in the company, it comes out ahead of a sole trader once profit passes roughly $140,000 (2025–26 rates). Remember that personal services income is taxed at your marginal rates whichever structure you use.
A family trust (discretionary trust) holds assets for a class of beneficiaries. The trustee decides each year how much income to distribute to each beneficiary. By directing income to members in lower tax brackets, the trust can reduce the overall family tax burden. Income retained in the trust is taxed at the top marginal rate plus the Medicare levy (47%).
Ongoing costs include the ASIC annual review fee ($342 a year for a proprietary company from 1 July 2026), preparing and lodging the company tax return and financial statements, and potentially payroll and BAS compliance. Accounting fees vary widely with activity levels and complexity, so get a quote before you switch.
