The company tax rate can look like a Roman victory, but a lower headline rate doesn’t automatically mean more money in your pocket. If you’re weighing the sole trader vs company tax rate australia 2026, the practical question is how much you’ll have left after business profit becomes personal take-home income.

In 2025-26, an eligible base rate entity company pays tax at 25%, while other companies pay 30%. As a sole trader, your business profit is taxed as your personal income. Those figures don’t tell the whole story, though. How much profit you need to draw, what you can leave in the business, and the extra costs and obligations of a company can all affect the result.

This guide compares how tax works for each structure and outlines the details to consider for your circumstances, including how company profits reach you. Use it to prepare more specific questions for a tax adviser. The aim is a practical roadmap, not a rushed verdict based on headline rates.

Sole trader vs company tax rate in Australia: why the headline comparison misleads

It’s understandable to think one rate should settle the question. But for a business owner in Perth, the relationship between business profit and personal income depends on your structure, other income and how you use business funds. The sole trader vs company tax rate australia 2026 comparison is a useful starting point, not a verdict.

A company tax rate applies to the company’s taxable income. It doesn’t, by itself, show the owner’s final personal tax outcome.

Question	Sole trader	Company
Who pays tax on business income?	The individual owner.	The company, as a separate taxpayer.
What income is assessed?	Business profit forms part of the owner’s taxable income, alongside other relevant income.	The company’s taxable income is assessed separately from the owner’s personal income.
When can the owner use business funds?	The owner and business aren’t separate taxpayers for business income tax purposes.	Company funds belong to the company. Paying money to an owner, such as through salary or dividends, has its own tax treatment.

What does “sole trader tax rate” mean?

A sole trader isn’t a separate taxpayer from the person who owns the business. The business’s taxable profit is included in that individual’s taxable income, and the tax payable depends on their overall circumstances, including other income and applicable deductions. Australia uses marginal tax rates, so one headline rate can’t describe every sole trader’s final bill. Check the ATO’s current 2025-26 resident tax brackets for the applicable rates.

What does “company tax rate” mean?

A company is a separate taxpayer and pays tax on its own taxable income. The rate can depend on whether it meets the ATO’s base rate entity criteria. For 2025-26, eligible base rate entities pay 25%, while other companies pay 30%. Check current eligibility with the ATO rather than assuming a company qualifies based on its size alone.

The company’s tax bill is only one part of the comparison. If profits are later paid to you as salary or dividends, your personal tax position may also matter. Australia’s dividend imputation system explains how franking credits can be relevant when dividends are taxed, helping account for tax already paid by a company.

For a clearer picture of the structure, consult a private company guide alongside current ATO information. Use it to understand how a company works, not as a recommendation that its tax rate will leave you better off.

How Australian sole trader and company tax works in 2025-26

For a fair comparison, keep three figures separate: business profit is what remains after business income and deductible expenses are accounted for; taxable income is the amount assessed for tax after relevant adjustments; and cash available to you is what you can actually use personally. These figures are related, but they aren’t interchangeable. This distinction matters more than comparing rates in isolation.

How a sole trader’s business income is taxed

A sole trader’s net business income is included in the owner’s individual tax return, along with other relevant income. For Australian resident individuals, the 2025-26 income tax brackets are:

• A$0 to A$18,200: 0%
• A$18,201 to A$45,000: 16%
• A$45,001 to A$135,000: 30%
• A$135,001 to A$190,000: 37%
• Above A$190,000: 45%

These are marginal rates. Each rate applies to the relevant portion of taxable income, not automatically to every dollar you earn. Most resident taxpayers also pay a 2% Medicare levy, although thresholds, exemptions and other circumstances can affect the amount. Check the ATO’s current guidance for your position. The 15% rate on income from A$18,201 to A$45,000 applies in 2026-27, not 2025-26, so check that you’re using the correct year’s figures.

How company profit and owner payments are taxed

A company calculates and pays tax on its own taxable profit. For 2025-26, the company rate is 25% for an eligible base rate entity and 30% for other companies. Eligibility includes an aggregated turnover below A$50 million and base rate entity passive income of 80% or less. Companies don’t receive an individual tax-free threshold. Confirm the criteria against current ATO guidance before applying a rate.

Company profit left in the company isn’t automatically the owner’s personal income. If the company pays you a salary, that income is assessed personally. If it distributes dividends, those have their own personal tax treatment. Franking credits can reflect tax already paid by the company and may be relevant when a shareholder reports a dividend. Retained profits aren’t permanently taxed only at the company rate.

Sole trader vs company: compare the tax outcomes that affect your take-home income

The useful comparison isn’t simply which rate looks lower. It’s how tax, access to business money, administration and your plans fit together. That’s why the sole trader vs company tax rate australia 2026 question needs your circumstances, not just a headline figure.

Consideration	Sole trader	Company
Tax treatment	Business profit is included in the owner’s individual taxable income.	The company is taxed on its taxable profit; salary and dividends received by the owner have separate personal tax implications.
Access to business funds	The owner can use business income directly, while still meeting tax and business obligations.	Company money belongs to the company. Taking funds personally needs to be handled and recorded appropriately.
Administration	Generally simpler to operate and report.	Includes separate company reporting and additional administration.
Planning focus	Consider personal income, cash needs and business record-keeping.	Consider owner payments, reinvestment plans and the responsibilities of running a company.

When a sole trader structure may suit your circumstances

A sole trader structure may suit you if you value a more straightforward setup and want direct access to business income. That simplicity doesn’t guarantee a lower tax bill. Your taxable income also reflects your other income and circumstances, so compare the full personal picture rather than business profit in isolation. Keep reliable records and consider whether your plans for growth could change the structure or administration you need.

When a company structure may be worth examining

A company may be worth examining if you plan to leave some profit in the business for reinvestment or want a structure that separates the company’s finances from your personal finances. But a lower company rate, where it applies, doesn’t automatically mean more personal take-home income. Salary is generally treated as your personal income. Dividends also affect your personal tax position, with franking credits potentially reflecting tax already paid by the company. Retained profit may defer personal tax until money is paid to you, but it doesn’t mean that profit will only ever be taxed at the company rate.

Factor in company administration and how you’ll draw funds. Business risk, personal cash needs and future plans also belong in the decision. There’s no single profit level that automatically makes incorporation the right move. Illustrative calculations can mislead if their assumptions don’t match your circumstances.

For a broader, lawful approach to planning, explore business tax minimisation services. A useful comparison should account for your income, intended drawings, reinvestment plans and the tax rules that apply when you make the decision.

A practical 2026 checklist for comparing your business structure

Before choosing a structure, give your tax adviser a clear picture of how your business works and what you need from its profits. Use this checklist to make a comparison more specific than a generic rate chart.

The best structure depends on more than its headline tax rate.

Information to gather before comparing structures

1. Organise your business records. Bring current information on business income and deductible expenses so the profit estimate starts with complete figures, not a rough guess.
2. Estimate expected business profit. Note the amount you expect for the period being compared, and explain any seasonal patterns or unusual changes that could affect it.
3. List your other personal income. Include income outside the business that may affect your individual tax position.
4. Set out your cash plans. Record how much you expect to draw for personal use, how much you might leave in the business, and whether you plan to reinvest retained profits.
5. Flag what may change. Note expected growth, changes to your role or personal income, and questions about company administration or changing structures. Ask your tax adviser whether other specialist advice may be needed before making a change.

Questions to ask your tax adviser

Ask for a side-by-side comparison using the same business assumptions for each structure. This helps show which differences come from the structure itself, rather than from changing estimates or inconsistent inputs. For the sole trader vs company tax rate australia 2026 decision, ask:

• What is the estimated total tax under each structure, including the effect of my other personal income?
• How much money could I access personally after tax, based on the drawings and reinvestment plans I’ve provided?
• For the company option, how would salary, dividends, franking credits and retained profit affect the comparison?
• Which assumptions, eligibility tests and current tax rules drive the result, and what could change it?
• What extra administration should I plan for, and what should I check before changing structures?

Ask your adviser to explain the result in plain language, not just give you a figure. If an assumption is unclear, pause and clarify it. For small business owners in Perth, advice should reflect actual income, cash needs and plans rather than treating a rate chart as a one-size-fits-all answer.

Bring your figures and questions to a discussion about your business and personal tax position. A useful comparison should clarify what the result means for the money you can use and the responsibilities you’ll take on.

Choose your next step: get a tailored sole trader vs company tax comparison

You’ve seen why the headline rate can’t settle the decision on its own. A useful comparison brings together the tax treatment for each structure, how and when you can access business funds, and the administration each option involves. The sole trader vs company tax rate australia 2026 question is best answered using your expected profit, other personal income, planned drawings and reinvestment intentions.

What a personalised comparison should clarify

A tailored comparison should show its assumptions rather than present a result without explaining how it was reached. It should consider your business plans and relevant tax circumstances, then explain how each structure may affect estimated tax, money available to you personally and the responsibilities of operating the business.

It should also distinguish between profit taxed in a company and money you receive personally, including the possible effects of salary, dividends and franking credits. The result depends on your circumstances and the rules that apply at the time. Rates and eligibility criteria can change, so confirm current ATO guidance before acting on a structure decision.

Incorporating doesn’t automatically reduce your overall tax or leave you with more take-home income. A company may suit particular plans, such as retaining profit for reinvestment, but administration and access to funds matter too. A clear explanation should cover potential benefits and trade-offs without promising a guaranteed saving.

Take a clear next step with a Perth-area adviser

If you’re a business owner in Perth and still feel stuck, bring your current business figures, personal income details and plans for the business to a tax discussion. Ask what assumptions the comparison uses and how the result could change if your drawings or reinvestment plans shift. That gives you a more useful roadmap than a generic rate chart.

Frequently Asked Questions

Is the company tax rate lower than the sole trader tax rate in Australia in 2026?

Sometimes, but it isn’t a like-for-like comparison. For 2025-26, eligible base rate entity companies pay 25% on company taxable income, while other companies pay 30%. Sole traders pay tax on business profit as part of their individual taxable income, using marginal rates. In the sole trader vs company tax rate australia 2026 comparison, remember that company tax isn’t the owner’s final personal tax. Check current ATO rates and eligibility before deciding.

How much tax does a sole trader pay in Australia in 2025-26?

It depends on the sole trader’s total taxable income and circumstances. For Australian resident individuals in 2025-26, rates are 0% up to A$18,200, then 16% to A$45,000, 30% to A$135,000, 37% to A$190,000, and 45% above that. These are marginal rates, not one rate applied to every dollar. Most resident taxpayers also pay the Medicare levy, subject to applicable thresholds and exceptions. Check current ATO guidance.

Can a company owner pay themselves a salary or dividends?

Yes. A company owner may receive salary, dividends, or both, but the tax treatment differs. Salary is generally part of the owner’s personal taxable income, and paying wages can involve payroll and withholding obligations. Dividends are reported under applicable rules; franking credits may reflect tax already paid by the company. The details depend on the arrangement and current rules, so check ATO guidance and get tailored tax advice before setting up payments.

Do sole traders pay tax on every dollar their business earns?

No. Tax isn’t generally calculated on gross business revenue alone. A sole trader works out business income after eligible business expenses, then reports net business income in their individual tax return. The resulting taxable income may also reflect other income and relevant adjustments. Which expenses can be claimed depends on the circumstances and tax rules, so keep complete records and confirm that any deduction is allowable with current ATO guidance or a tax adviser.

What happens if a company keeps its profits instead of paying them to its owner?

Profit retained in the company is still assessed as the company’s taxable income and taxed at the applicable company rate. Keeping it in the business doesn’t automatically make it the owner’s personal income. If the company later pays salary or distributes dividends, those payments can have personal tax consequences. The eventual outcome depends on the payment type, the owner’s circumstances and current rules, so don’t assume retained profit is permanently taxed only at the company rate.

When should a sole trader consider becoming a company?

Consider reviewing the structure when your business plans, reinvestment needs, risk profile, cash requirements or administration capacity change. There isn’t a universal income threshold that makes incorporation right for everyone. Compare likely tax outcomes alongside how you’ll access business funds and manage company responsibilities. For owners in Mount Pleasant, Applecross, Attadale, Brentwood, Booragoon, South Perth and Como, tailored tax and business advice can help make the decision clearer.

Is changing from a sole trader to a company automatically a way to pay less tax?

No. A company may pay tax at a different rate on its profit, but that doesn’t guarantee lower total tax or more personal take-home income. Consider how you’ll pay yourself, whether profits will stay in the business, and the company’s extra administration. Your other income, eligibility for a company rate and individual circumstances all matter. Before changing structure, ask a tax adviser to compare both options using the same assumptions and current rules.
