You can pay less tax legally in Australia by claiming every deduction you are entitled to, using the right business structure, contributing to super within the caps, timing income and expenses, and planning before 30 June rather than after. Legitimate tax planning uses the law as intended and is very different from tax evasion. Innovative companies should also look at the R&D Tax Incentive, a refundable offset that can return up to 43.5 percent of eligible spend.

Every year, Australian business owners hand the ATO more money than they legally need to. Not through fraud or error — but through inaction, poor structure, and the simple failure to plan ahead. If your tax bill feels shocking every June, that’s a sign your current approach is reactive rather than strategic. In this post, I’m sharing the eight most powerful and entirely legal strategies I use with my clients to reduce their tax burden — and keep more of what they earn working for them.

Why Most Business Owners Overpay Tax

The Australian tax system is complex, but it is also remarkably generous to those who understand and use its rules. The problem is that most business owners are focused on running their business — not on optimising their tax position. They rely on an accountant who processes their returns but doesn’t proactively advise on structure. They make decisions in isolation — buying assets, paying family members, withdrawing from their company — without understanding the tax implications. And they wait until after 30 June to think about tax, by which point most opportunities have already closed.

The good news is that every strategy I’m about to share is available to you right now. We’ve written about the biggest tax mistakes Australians make — read that too, because avoiding mistakes is just as important as implementing strategies.

Strategy 1: Operate Through the Right Business Structure

Your business structure is the foundation of your tax position. Operating as a sole trader when you’re earning over $100,000 is almost always costing you money. As a sole trader, every dollar of profit is taxed at your personal marginal rate — up to 47% including Medicare levy.

Moving to a company capped at 25–30%, or a discretionary trust that allows income splitting across the family group, can dramatically reduce your effective tax rate. This is the single biggest lever most business owners can pull — and it requires proper advice to implement correctly without triggering CGT or stamp duty on the transition. See our approach to tax planning here.

Strategy 2: Income Splitting Through a Family Trust

A family (discretionary) trust allows the trustee to distribute income to multiple beneficiaries — each taxed at their own marginal rate. This is one of the most powerful income-splitting tools available in Australia.

For example: if your business generates $250,000 in profit and you have a spouse earning $60,000 from other sources, you can distribute income from the trust to fill their lower tax brackets, to adult children who are studying or working part-time, and to a bucket company. Done correctly, you might reduce your effective tax rate from 47% to an average of 28–32% across the family group — a substantial annual saving.

The ATO’s Section 100A rules apply here — distributions must not be made to a low-rate beneficiary where the economic benefit is enjoyed by a higher-rate beneficiary. Proper documentation and genuine arrangements are essential.

Strategy 3: Use a Bucket Company to Cap Your Tax Rate

When all family members are already fully utilising their lower tax brackets, the next dollar of trust income faces the top marginal rate. The solution is a bucket company — a corporate beneficiary that receives excess trust distributions and pays company tax at 25% instead of the 47% that would otherwise apply.

On a $100,000 distribution to a bucket company vs an individual in the top bracket, the tax saving is $22,000. Over multiple years, these savings compound significantly. The funds in the bucket company can then be invested — in shares, property, or back into the business — providing further returns on the tax saved.

Strategy 4: Maximise Superannuation Contributions

Superannuation is the most tax-advantaged long-term savings vehicle in Australia, and it’s one that business owners consistently under-utilise. Here’s why it’s so powerful:

• Concessional contributions (employer contributions, salary sacrifice, personal deductible contributions) are taxed at 15% inside the fund — compared to your personal marginal rate of up to 47%
• The 2026–27 concessional cap is $30,000 per person per year
• If you have unused concessional cap from the past five years (and your super balance is under $500,000), you can make catch-up contributions — potentially contributing much more in a single year
• Spouse contributions and contributions on behalf of a spouse can also provide tax offsets

A business owner making a $30,000 concessional contribution who would otherwise be taxed at 47% saves approximately $9,600 in tax on that contribution — and the money continues to grow in a tax-advantaged environment. Read about the 2026 payday super changes affecting employers.

Strategy 5: Instant Asset Write-Off and Accelerated Depreciation

Australian tax law provides generous deductions for businesses that invest in assets. The instant asset write-off allows eligible small businesses to immediately deduct the full cost of qualifying assets rather than depreciating them over time. This brings forward the tax deduction — reducing your taxable income in the year you acquire the asset.

For a business purchasing a $50,000 piece of equipment in June 2026 and claiming it as an immediate deduction at a 25% tax rate, the net cost after tax is $37,500. The timing of asset purchases — particularly around the end of the financial year — can have a meaningful impact on your tax bill. Read our complete guide to the instant asset write-off for 2026.

Strategy 6: Pre-Year-End Tax Planning

June is not when tax planning happens — it’s when tax planning concludes. The real work is done in March through May, when there’s still time to act on what you find. Pre-year-end planning involves:

• Reviewing your profit to date and projecting year-end position
• Deciding on trust distributions before 30 June
• Making super contributions before 30 June
• Prepaying deductible expenses where appropriate (e.g. insurance, subscriptions, interest on investment loans)
• Reviewing capital assets — selling underperforming assets before year-end to crystallise losses that offset gains
• Timing invoices and purchases to shift income and deductions between years where appropriate

Business owners who engage in proactive pre-year-end planning consistently pay less tax than those who don’t. The best time to start is now — for the 2026–27 year, get your planning conversations happening in March or April 2027, not June.

Strategy 7: Income Splitting With a Spouse or Family Member

Beyond trust distributions, there are several legitimate ways to direct income to a spouse or family member in a lower tax bracket:

• Employ your spouse: If your spouse works in the business — even part-time in an administrative capacity — paying them a salary that reflects the market rate for their services is tax deductible. The salary is taxed at their lower marginal rate.
• Superannuation contributions for a spouse: You can make non-concessional contributions to your spouse’s super and receive a tax offset of up to $540 if their income is under $37,000.
• Shareholding in a company: If a family member holds shares in your company, dividends can be paid to them proportional to their shareholding — subject to the family trust rules and the company’s constitution.

These strategies must reflect genuine commercial arrangements. The ATO scrutinises salary payments to family members — the amount paid must be commercially reasonable for the work performed.

Strategy 8: Work With a Proactive Advisor, Not Just a Compliance Accountant

Perhaps the most impactful “strategy” of all is not a tax technique — it’s choosing the right accountant. There is a significant difference between an accountant who prepares your returns and an advisor who actively works to reduce your tax burden year-round.

A proactive tax advisor will:

• Review your structure annually and recommend changes as your circumstances evolve
• Contact you before 30 June with specific, actionable recommendations
• Model the tax impact of major decisions before you make them (buying a property, hiring staff, restructuring)
• Keep you informed of ATO changes and new legislation that affects your position
• Help you build long-term wealth through tax-efficient investing, not just manage last year’s tax

Most of my clients tell me the same thing when they first come to Pinnacle: their previous accountant was perfectly competent at compliance but never proactively reached out to suggest ways to save money. That reactive approach costs business owners dearly over time.

Frequently Asked Questions

Is it legal to minimise tax in Australia?

Absolutely. The High Court of Australia has affirmed the right of taxpayers to arrange their affairs in a way that minimises their tax liability, provided they do not engage in fraud, evasion, or arrangements that fall within the general anti-avoidance rules (Part IVA of the ITAA 1936). Every strategy in this article is legal, well-established, and used by thousands of Australian business owners.

How much can I realistically save?

It depends entirely on your income, structure, and family situation. Business owners earning over $200,000 in business profit who are operating under a suboptimal structure often save between $20,000 and $60,000 per year once properly structured. The savings grow as income grows. Speak to Mina for a specific assessment of your situation.

When is the best time to start tax planning?

The best time was when you first started your business. The second best time is right now. For the current financial year (2026–27), there’s still time to implement most of these strategies — but don’t wait until June. Many opportunities close at year-end and cannot be applied retrospectively.

What is the difference between tax minimisation and tax evasion?

Tax minimisation (or avoidance) is legal — it involves arranging your affairs within the law to reduce the tax you owe. Tax evasion is illegal — it involves deliberately hiding income, falsifying records, or making fraudulent claims. Everything in this article is legal tax minimisation. If an advisor suggests something that feels like it crosses a line, get a second opinion.
