How Tax Time Can SAVE You Money, Not Cost You

Most Australians view tax time as a financial burden — just another bill that eats into your hard-earned income. But what if tax time could work in your favour? At SuperTax, we’ve helped thousands of individuals and businesses legally reduce their taxable income and keep more money where it belongs — in your pocket, in your super, or growing in your investment portfolio.

Here’s the truth: Every dollar you reduce from your taxable income saves you between 16 and 45 cents in tax, depending on your income bracket. That means if you earn $95,000 and reduce your taxable income by $10,000, you could save around $3,000 in tax. That’s money that could be used to boost your super, pay off debt, or invest for the future.

Let’s break down the smart ways to reduce your taxable income in 2025.

What Counts as Taxable Income in Australia?

Your taxable income includes more than just your salary. It can come from:

• Wages and salaries
• Bank interest and dividends
• Rental income
• Business profits
• Capital gains
• Foreign income
• Freelancing, gig work, YouTube income, and even cash jobs

But not all income is taxed the same way. Understanding the three types of income will help you save tax legally:

1. Assessable Income (Taxed)

• Salary and wages
• Bank interest, dividends
• Rental property income
• Business income and capital gains
• Foreign income (if you’re a tax resident)

2. Exempt Income (Not Taxed, But Declared)

• Some Centrelink payments
• ADF and AFP allowances
• Some education-related payments
• Certain insurance payouts

3. Non-Assessable, Non-Exempt Income (NANE)

• Genuine redundancy payments
• Super co-contributions
• Disaster recovery payments
• Tax-free portion of ETPs

Understanding these categories helps you stay compliant with the ATO while maximising deductions and minimising tax.

The 2024–25 Australian Income Tax Rates

Australia uses a progressive tax system, which means higher incomes pay a higher tax rate. For 2024–25:

• Taxable Income Tax Rate
• $0 – $18,200 Nil
• $18,201 – $45,000 16c for each $1 over $18,200
• $45,001 – $135,000 $4,288 + 30c per $1 over $45,000
• $135,001 – $190,000 $31,288 + 37c per $1 over $135,000
• $190,001 and over $51,638 + 45c per $1 over $190,000

Pro tip: The more you can move income out of higher brackets — using deductions or contributions — the more tax you save.

Super Contributions: A Goldmine for Tax Savings

Super is one of the most effective ways to reduce your taxable income while building your future wealth.

Concessional Contributions (Pre-tax)

• 2024–25 cap: $30,000
• Taxed at 15% (often lower than your marginal rate)
• Includes employer contributions, salary sacrifice, and deductible personal contributions
• Must lodge a Notice of Intent to claim personal deductions

Non-Concessional Contributions (After-tax)

• 2024–25 cap: $120,000
• No deduction available, but investment earnings grow tax-effectively
• May qualify for “bring-forward rule” to contribute up to $360,000 over 3 years

Tip: Salary sacrifice arrangements can lower your tax and grow your super automatically.

Work-Related Deductions to Lower Taxable Income

Many Australians miss hundreds (even thousands) in eligible deductions each year. Don’t leave money on the table.

Updated Deduction Opportunities for 2024–25:

Work-from-Home Expenses

• $0.70/hour fixed rate
• Covers phone, internet, stationery, electricity
• Detailed record-keeping is essential

Vehicle Expenses

• 88 cents/km method for up to 5,000km (no logbook needed)
• Logbook method available for larger claims

Self-Education Expenses

• Courses, textbooks, travel
• No longer subject to the $250 minimum threshold

Tools & Equipment

• Items under $300 — instant deduction
• Larger items — depreciated over time
• Small businesses: Up to $20,000 instant asset write-off

Investment-Related Deductions

• Property expenses (interest, maintenance, etc.)
• Ongoing advice fees
• Financial subscriptions

Commonly Missed Deductions

• Laundry for uniforms
• Work-related mobile phone usage
• Union or professional fees
• Income protection premiums
• Tax agent fees

Record-keeping is crucial. The ATO cross-checks over 350 data sources.

Don’t Forget About Tax Offsets

Tax offsets reduce the tax you owe, not just your taxable income. Some worth knowing:

• Spouse super contribution offset
• Zone tax offset (for regional/remote residents)
• Invalid or carer offset
• Early-stage investor offsets
• Foreign income tax offset
• Landcare and water facility offset

These offsets can significantly reduce your final tax bill — but they’re easy to miss without expert help.
