Every year in our Mildura office, we see the same pattern. In early June, the phone starts ringing. “Is there anything we can still do before 30 June?” Sometimes there is. Sometimes the window has narrowed.
Reducing taxable income is not about last-minute scrambling. It is about steady planning across the financial year. The 2025–2026 year brings updated tax brackets, tighter ATO data matching, and changes to super rules. With the right structure, you can legally reduce tax, improve cash flow, and strengthen long-term wealth.
Below, we outline practical strategies we use with clients across Sunraysia — from employees and tradies to business owners and investors.
Understanding the 2025–2026 Tax Framework
How Marginal Tax Rates Affect Real Decisions
Australia’s tax system is progressive. You pay higher rates only on the portion of income above each threshold. Yet many people still believe earning more pushes all income into a higher bracket. That is not how it works.
The key principle is simple:
Taxable Income = Assessable Income – Allowable Deductions
When you reduce taxable income, you reduce the amount taxed at your highest marginal rate.
For example, consider a professional earning $155,000:
|
Scenario |
Taxable Income |
Marginal Rate Applied to Top Portion |
Approx. Tax Impact |
|
No planning |
$155,000 |
37% |
Higher exposure |
|
$10,000 deduction |
$145,000 |
Reduced top-rate exposure |
~$3,700 saved |
That $10,000 deduction effectively avoids tax at 37% plus Medicare levy. This is why timing and structure matter.

What Counts as Assessable Income and Deductions?
Assessable income typically includes:
- Salary and wages
- Bonuses and commissions
- Rental income
- Dividends
- Capital gains
Common deductions include:
- Work-related expenses
- Investment interest
- Income protection insurance
- Super contributions
- Accounting fees
The formula is straightforward. The execution requires planning.
Superannuation — The Strongest Tax Lever Available
Superannuation remains one of the most effective tools for reducing taxable income.
Salary Sacrifice and Concessional Contributions
For 2025–2026, the concessional contribution cap is $30,000. Contributions are generally taxed at 15% within the fund.
Compare this to personal marginal tax rates:
|
Income Level |
Personal Marginal Rate |
Super Contributions Tax |
Tax Advantage |
|
$120,000 |
30% |
15% |
15% difference |
|
$155,000 |
37% |
15% |
22% difference |
|
$250,000+ |
45% |
30% (Div 293 applies) |
Still lower than 45% |
Example:
A local agribusiness manager earning $150,000 salary sacrifices $15,000.
- Personal tax avoided: approx. $5,550
- Contributions tax: $2,250
- Net tax saved: approx. $3,300
That saving compounds over time.
Carry-Forward Contributions Before 30 June 2026
If your super balance is under $500,000, you may access unused concessional caps from the previous five years.
This works well for:
- Business owners after a profitable year
- Farmers following a strong harvest
- Professionals receiving large bonuses
Checklist before 30 June 2026:
- Confirm unused caps via ATO online services.
- Check total super balance.
- Ensure contributions clear your fund before 30 June.
Every year, someone transfers funds on 30 June and misses the deadline. We advise acting by mid-June.
High-Income Earners and Division 293
If income exceeds $250,000, Division 293 adds another 15% tax on concessional contributions.
Even so:
- Total super tax may be 30%.
- Top marginal personal tax remains 45% plus Medicare levy.
Super still offers tax efficiency. Planning contributions carefully becomes more important as balances approach higher thresholds.
Maximising Work-Related Deductions
The ATO’s three golden rules apply:
- You must have spent the money.
- The expense must relate directly to earning income.
- You must keep records.
H3: Working From Home Claims
For 2025–2026, you can choose:
- Fixed rate method (67 cents per hour), or
- Actual cost method.
To substantiate claims, keep:
- Diary records of hours worked.
- Utility bills.
- Internet statements.
In regional areas like Mildura, where travel distances are large and remote work is common, WFH claims are legitimate. However, claiming 100% of internet costs rarely reflects reality.
Vehicles, Tools, and Education
You may claim:
- Immediate deduction for tools under $300.
- Depreciation for higher-value assets.
- Travel between work sites.
- Self-education directly related to current employment.
Example:
A local electrician travels between multiple client sites daily. Using a logbook showing 70% business use, he claims fuel, servicing, registration, and depreciation proportionately.
Accurate records reduce audit risk.
Timing Strategies That Shift Your Tax Position
Sometimes tax planning is about the calendar.
Prepaying Deductible Expenses
The ATO allows prepayment of up to 12 months of certain expenses.
Common prepaid items:
- Investment loan interest
- Income protection premiums
- Professional memberships
- Accounting fees
Example:
An investor prepays $10,000 in loan interest in June 2026. That full amount reduces 2025–2026 taxable income.
This strategy suits those expecting lower income next year.
Deferring Income
If you sit near a higher bracket, deferring income may help.
Possible options:
- Delay discretionary bonuses.
- Defer issuing business invoices.
- Time capital asset sales.
We assisted a Mildura contractor who delayed a $35,000 invoice until July. That decision kept him below a higher threshold in the current year.
Small timing adjustments can produce meaningful results.
Investment Planning and Tax Outcomes
Negative Gearing Explained
Negative gearing occurs when investment expenses exceed income.
The loss can offset salary income.
Example:
|
Item |
Amount |
|
Rental income |
$25,000 |
|
Expenses |
$35,000 |
|
Net loss |
$10,000 deduction |
That $10,000 reduces taxable income.
However:
- Cash flow must be sustainable.
- Long-term capital growth should justify the strategy.
Tax benefits should support investment decisions, not drive them.
Capital Gains Tax (CGT) Strategy
Holding assets longer than 12 months generally qualifies for a 50% CGT discount.
Example:
|
Capital Gain |
Holding Period |
Discount |
Taxable Gain |
|
$100,000 |
18 months |
50% |
$50,000 |
Other CGT planning strategies:
- Offset gains with capital losses.
- Spread asset sales across financial years.
- Consider super contributions in high-gain years.
Timing matters.
Investment Bonds and ESIC Opportunities
Investment bonds:
- Taxed internally at up to 30%.
- Withdrawals after 10 years may be tax-free.
- No personal reporting after the 10-year period.
Early Stage Investment Companies may offer:
- 20% tax offset.
- CGT exemptions in some cases.
These strategies suit higher-income investors and require careful assessment.

Structuring for Families and Business Owners
Discretionary Family Trusts
Trusts allow income distribution to beneficiaries in lower tax brackets.
Example scenario:
Rental income of $80,000 distributed between two adult children studying full-time can reduce overall family tax compared to one high-income parent receiving it.
Key considerations:
- Trust must be established before asset purchase.
- Annual trustee resolutions must be completed before 30 June.
Bucket Companies
A trust may distribute profits to a company taxed at 25% or 30%.
Benefits include:
- Retaining profits at lower tax rates.
- Reinvesting earnings within the company.
- Managing personal tax exposure.
Proper documentation is essential.
Debt Recycling
Debt recycling converts non-deductible home loan debt into deductible investment debt.
Typical steps:
- Reduce home loan principal.
- Redraw funds for investment.
- Claim interest on investment portion.
This strategy requires discipline and strong cash flow management.
Levies, Offsets, and Small Adjustments
Medicare Levy Surcharge
Singles earning above $90,000 and families above $180,000 may face the surcharge without private hospital cover.
Comparison example:
|
Scenario |
Surcharge Cost |
Basic Hospital Cover |
Net Outcome |
|
No cover |
1–1.5% of income |
$0 |
Higher cost |
|
With cover |
$0 surcharge |
Premium payable |
Often lower overall |
For many, hospital cover costs less than the surcharge.
Offsets and Spouse Contributions
Offsets reduce tax payable dollar-for-dollar.
Examples:
- Low Income Tax Offset (up to $700).
- Spouse super contribution offset (up to $540).
Small contributions can generate measurable savings.
Mortgage Offset Accounts
Interest earned in savings accounts is taxable.
Interest saved in a mortgage offset account is not taxed.
For many families, shifting savings into an offset account improves after-tax returns without increasing risk.
Record-Keeping and Avoiding ATO Scrutiny
The ATO uses data matching across:
- Banks
- Employers
- Super funds
- Investment platforms
You must keep records for five years, including:
- Receipts
- Logbooks
- Contribution confirmations
- Bank statements
Common pitfalls we see:
- Claiming private expenses as work-related.
- Missing super contribution deadlines.
- Failing to finalise trust resolutions on time.
Preparation reduces stress and penalties.
Reducing taxable income is not about clever tricks. It is about steady, informed planning.
In regional communities like Mildura, income can fluctuate with seasons, harvests, and business cycles. That makes forward planning even more important.
Start early. Review regularly. Keep proper records. Seek advice when needed.
Tax planning rewards those who stay ahead of the curve rather than chasing the clock in June.
