Expert Advice: Key Changes In Taxation Law

Tax law rarely changes overnight, but when it does shift, the effects ripple through households, businesses, and balance sheets faster than most people expect. In Australia, the 2025–2026 tax year marks one of those turning points. Between personal income tax cuts, tighter ATO compliance, changes to superannuation, and the quiet rise of data matching and AI-led audits, the rules Australians have relied on for years are being reshaped. We see this daily in practice from Mildura tradies caught out by GST drift, to family trusts under fresh scrutiny, to business owners assuming old strategies still hold water. This guide cuts through the noise and focuses on what actually matters, what has changed, and what Australians need to get right now, before small oversights turn into expensive lessons.

Australian Tax Updates – Key Changes for 2025-2026

Australia’s tax system is always evolving, and the 2025–2026 tax reforms are no exception. The government has introduced a set of tax cuts aimed at reducing the burden on working Australians, particularly those in the middle-income brackets.

1. Personal Income Tax Cuts: Effective July 1, 2026, the rate for the A$18,201–A$45,000 tax bracket will drop from 16% to 15%, and this rate will fall even further to 14% by 2027. For anyone living in an urban area, like Sydney or Melbourne, this change will have a meaningful impact. It’s a bit of relief for families juggling everyday costs, particularly with the rising cost of living.
   
   
2. Superannuation Guarantee (SG): From July 1, 2025, Australia’s Superannuation Guarantee rate will increase to 12%. This means more money is being put away for retirement, which is particularly important as we face an ageing population and greater demand for aged care. As someone who’s recently been thinking about retirement planning, I can say that a higher SG rate makes a real difference in building a strong super balance over time.
   
   
3. Super Balance Tax: A major change that will impact high-income earners is the Large Super Balance Tax (Division 296). Starting July 1, 2026, there will be an additional tax on superannuation balances over A$3 million. This tax will only apply to realised earnings (so no unrealised gains), which should give some peace of mind to those of us with a bit more in super. As a reminder, always check in with your financial advisor to ensure you’re on track, especially if you have a significant balance.
   
   

Tax Compliance and ATO Focus Areas

The Australian Taxation Office (ATO) has been ramping up its focus on high-risk areas. With increasing scrutiny, taxpayers are expected to be more diligent than ever.

1. Transfer Pricing: The ATO has been intensifying its efforts to review transfer pricing arrangements. For businesses operating internationally, this is critical. If you’re managing an Australian business with overseas dealings, now is the time to review your transfer pricing policies and make sure everything is above board. Transfer pricing audits are on the rise, and businesses must demonstrate that their pricing strategies align with the arm’s length principle.
   
   
2. Private Use of Company Money: Division 7A, which governs the private use of company money, is another area under the ATO’s microscope. If you’re running a business and using company assets or loans for personal purposes, you could be subject to hefty penalties. Always be cautious about how funds are used within your business to avoid any surprises at tax time.
   
   
3. High-Risk Trust Distributions: The ATO has been paying close attention to high-risk trust distributions, particularly when it comes to ensuring that trusts are distributing income properly. Trusts are often used for tax planning, but the ATO wants to ensure that income is being distributed according to the tax rules and not for the purpose of tax avoidance.
   
   

Corporate Taxation – Navigating Business Reforms

The Australian government has made significant changes to corporate taxation, aimed at driving business growth and ensuring companies contribute their fair share to the economy.

1. Corporate Tax Rate: The corporate tax rate for businesses with an annual turnover of less than A$50 million has been reduced to 25% for the 2025-2026 period. This reduction aligns with the government’s focus on supporting small and medium-sized businesses, which are the backbone of the Australian economy. For those who run a family business or a startup, this is a welcome change that can free up more resources for reinvestment.
   
   
2. R&D Tax Incentives: The R&D Tax Incentive has been expanded to encourage more businesses to invest in innovation. Small and medium-sized enterprises (SMEs) are now eligible for a refundable R&D tax offset, allowing them to claim back up to 43.5% of their R&D expenses. This is a great opportunity for businesses in the technology and manufacturing sectors to gain financial support for research and development efforts.
   
   
3. Small Business Deductions: For those of us running small businesses, there are also new deductions on offer. The government has introduced a temporary instant asset write-off for assets up to A$30,000. This means small businesses can immediately deduct the cost of assets, such as new equipment, from their taxable income. If you’re in the construction or retail sectors, this could mean major savings when upgrading equipment.
   
   

Indirect Taxes, and What the ATO Is Watching Closely

On paper, GST looks straightforward. Ten per cent on most goods and services. In practice, this is where many small businesses come unstuck.

We see it every year, especially around BAS season, when business owners realise too late that GST has quietly drifted off course.

Key GST pressure points in 2025–2026:

• Incorrect GST treatment on mixed supplies
  
  
• Claiming GST credits without valid tax invoices
  
  
• Errors in cash vs accrual reporting
  
  
• Online sales and platform fees (Shopify, Uber, Airbnb)
  
  

Common real-world scenario:
A Mildura-based trades business registers for GST after hitting the A$75,000 threshold. They invoice correctly, but forget to set aside the GST collected. Twelve months later, the ATO comes knocking. The tax bill lands right as work slows over winter. Cash flow tightens. Stress levels spike.

That situation is avoidable.

Simple GST checklist we use with clients:

• Register once turnover approaches A$75,000
  
  
• Separate GST into a dedicated bank account
  
  
• Reconcile BAS quarterly, not yearly.
  
  
• Review GST codes in Xero or MYOB every quarter.
  
  

“GST rarely causes problems overnight. It causes problems through small mistakes repeated for too long.”

Indirect Taxes Beyond GST

While GST dominates the conversation, other indirect taxes matter depending on industry and location.

Personal Income Tax – What Actually Changes for Australian Taxpayers

From 1 July 2026, the government’s staged tax cuts start to bite.

Taxable Income	Current Rate	From July 2026	From July 2027
A$18,201 – A$45,000	16%	15%	14%

For a full-time worker on A$45,000, that’s not life-changing money. But combined with rising wages and super contributions, it helps.

In regional areas like Mildura, where wages often trail capital cities,s but costs keep rising, every dollar counts.

Deductions That Still Matter

Despite talk of reform, tax deductions remain central to personal tax outcomes.

Common deductions that still hold up under ATO scrutiny:

• Work-related vehicle expenses
  
  
• Home office running costs
  
  
• Self-education is tied directly to income.
  
  
• Tools, uniforms, and protective gear
  
  

ATO red flags we see often:

• Claiming “work from home” without evidence
  
  
• Logbooks older than five years
  
  
• Split private and work expenses are guessed, not calculated.
  
  

Short rule of thumb:
If you can’t explain it in plain English, don’t claim it.

Wealth, Super, and Estate Tax Issues Australians Need to Watch

From 1 July 2026, individuals with super balances above A$3 million face extra tax under Division 296.

Key point that caused confusion early on:
Only realised earnings are taxed. Unrealised gains were dropped from the final design.

This matters for:

• SMSF trustees
  
  
• Business owners holding property in a superannuation fund.
  
  
• Long-term investors nearing retirement.
  
  

Planning timeline:

• 2024–2025: Review projected balances
  
  
• 2025–2026: Model contribution strategies
  
  
• From July 2026: Monitor realised gains carefully.
  
  

Estate Planning and Tax Exemptions

Australia does not have a formal estate tax, but tax still appears on death through:

• Capital gains tax events
  
  
• Superannuation death benefit tax
  
  
• Trust distribution consequences
  
  

We often see outdated wills and binding death benefit nominations causing tax outcomes no one intended.

International Taxation, Digital Business, and Transfer Pricing

The ATO has made it clear: transfer pricing applies to more than multinationals.

We now see audits involving:

• Australian companies with overseas contractors
  
  
• IP held offshore
  
  
• Related-party loans
  
  

If money moves across borders, documentation matters.

ATO expectations:

• Arm’s length pricing
  
  
• Commercial rationale
  
  
• Consistent reporting year to year
  
  

Digital Taxation and Global Reporting

Australia continues to align with OECD standards, including:

• Global minimum tax frameworks
  
  
• Expanded data sharing
  
  
• Digital platform reporting
  
  

Crypto, online marketplaces, and foreign income are no longer “grey areas”.

The ATO already receives data from:

• Banks
  
  
• Payment platforms
  
  
• Crypto exchanges
  
  
• Foreign tax authorities
  
  

Tax Compliance, Audits, and the Rise of Data Matching

ATO Compliance Focus for 2026

The ATO has flagged specific focus areas:

• Division 7A loans
  
  
• Trust income distributions
  
  
• Rental property deductions
  
  
• International dealings
  
  

Audits today are less about random selection and more about data mismatches.

How audits usually start:

1. Data mismatch detected
   
   
2. Review the letter issued.
   
   
3. Short response window
   
   
4. Audit escalates if unanswered.

AI, Data Matching, and How the ATO Now Spots Problems Early

The ATO no longer relies on chance. The days of audits being triggered by gut feel are gone. What we see now is pattern-based detection, powered by data and artificial intelligence.

From our side of the desk, this shift is obvious.

Clients receive letters not because they did something dramatic, but because something didn’t line up.

What the ATO’s systems now compare automatically:

• Bank interest vs tax return disclosures
  
  
• Property income vs land title data
  
  
• Ride-share and delivery income vs platform reports
  
  
• Crypto transactions vs exchange data
  
  
• Trust distributions vs beneficiary returns
  
  

Once a mismatch appears, the system flags it. A review follows. Silence escalates it.

“The ATO doesn’t need proof to ask questions. It only needs a pattern.”

Tax Avoidance vs Tax Evasion — Where Australians Get It Wrong

We hear this phrase often:
“I’m just doing what everyone else does.”

That thinking gets people into trouble.

Tax avoidance involves using the law as written.
Tax evasion involves hiding, omitting, or misrepresenting facts.

The ATO focuses less on labels and more on intent and behaviour.

Common Risk Areas the ATO Targets

• Income splitting through trusts withouta  commercial basis
  
  
• Repeated losses from “hobby” businesses
  
  
• Private expenses run through companies.
  
  
• Offshore income is not disclosed.
  
  

ATO View in Plain Terms

If it looks artificial, temporary, or circular, expect questions.

We advise clients to ask one simple question before implementing any strategy:

“Would this still make sense if tax wasn’t involved?”

If the answer is no, rethink it.

Environmental Taxes and Incentives — Quiet but Growing

Australia does not have a broad carbon tax, but environmental measures are spreading through targeted incentives and levies.

Examples include:

• Fuel efficiency incentives
  
  
• Electric vehicle FBT exemptions
  
  
• Renewable energy write-offs
  
  
• State-based environmental levies
  
  

These changes often sit outside income tax returns but still affect total tax outcomes.

EV and FBT Changes in Practice

The FBT exemption for eligible electric vehicles has been a game-changer for some businesses.

Who benefits most:

• Professional services
  
  
• Trades with metro travel
  
  
• Salary packaging arrangements
  
  

But eligibility rules are tight. We’ve seen clients assume exemption applies, only to find the vehicle price or use pattern disqualifies it.

Practical Planning Steps for Individuals and Small Businesses

For Individuals

• Review deductions before 30 June, not after
  
  
• Check PAYG withholding matches expected income.
  
  
• Confirm super contributions hit accounts on time.
  
  
• Update records for home office and vehicles
  
  

For Small and Medium Businesses

• Review Division 7A loan balances annually
  
  
• Reconcile GST quarterly
  
  
• Document trust distribution decisions
  
  
• Reassess structures every two to three years.
  
  

Short checklist we use internally:

• Structure still fit for purpose
  
  
• Compliance risk low
  
  
• Records are up to date.
  
  
• Strategy still commercial
  
  

As we approach the 2026 tax year, significant changes in Australia’s tax system offer both opportunities and challenges for individuals and businesses. Tax cuts, higher superannuation contributions, and tighter ATO compliance measures mean it’s essential to stay informed. These reforms can bring savings, but they also require careful planning to avoid mistakes and maximise benefits.

To make the most of these changes, it’s important to plan ahead and review your tax strategy now. Whether you’re an individual or a business, understanding these updates and seeking professional advice will help you navigate the new rules, stay compliant, and optimise your financial position moving forward.
